The initiative is intended to weatherize owner-occupied, single family homes and multi-family units (6 units or fewer) that are located in areas with high rates of unemployment, underemployment, and poverty as defined by the 2010 census and are identified by the Urban Weatherization Initiative Board of Directors. Legislative Background The Urban Weatherization Initiative Program is administered by the Department’s Office of Urban Assistance as authorized under the provisions of the Urban Weatherization Initiative Act (30 ILCS 738) (Act) and is overseen by the Weatherization Initiative Board. The Act authorizes DCEO to plan, establish, administer, and expand the delivery of weatherization services to eligible households within the identified areas. Funds for the Residential Weatherization Program are made available to the Department from the Build Illinois Bond Fund. Program Design This overview provides a general idea of how the program works and a review of the rules and procedures which will govern the Residential Weatherization Program (RWP). How the Program Works The Residential Weatherization Program is geared to assist families residing in communities where 20% or more of the population is living in poverty and that suffer from disproportionately high rates of unemployment, underemployment, and poverty as identified by the 2010 Census. In addition, this grant will service areas with high concentrations of families with income equal to or less than 60% of the Area Median Income. Although most dwellings waste energy, different types of houses and apartments have different energy issues that can include heat loss; cold air seeping in through cracks, around doors, walls, and ceilings. Depending on the circumstance and condition of the dwelling, weatherization services include: Addressing of air filtration with weather stripping, caulking, thresholds, minor repairs to walls, roofs, ceilings, and floors; Insulating attics, walls, and floors; Repairing windows and doors; Replacing non-repairable windows or doors; Repair or replacement of inefficient heating and cooling units; Repair or replacement of water heaters; and Pipe, duct, or pipe and duct insulation. I.1 The Weatherization Program has seven basic steps: 1. A potential applicant will apply at a location identified by the Grantee by completing an application for the program. 2. The Grantee determines if the potential applicant meets the eligibility requirements based on the income specifications as set by the legislation. 3. A Home Energy Audit will be conducted on the home, and the weatherization measures that will save the most energy are printed on a Work Order. The Supervisor will be responsible for reviewing, approving and signing off on all work orders completed before any work is initiated on the home. 4. All work orders will be competitively bid out by the Grantee in groups of 5-10. Those contractors who have won the bid will take the Work Order and complete the weatherization repairs, using high-quality materials that meet federal energy savings standards. 5. A HVAC (Heating Ventilation and Air Conditioning) certified contractor will inspect the furnace to make sure that it is safe and in good working order and make the necessary repairs, retrofits, or replace the furnace. The Architectural contractor will complete work on the shell of the unit to reduce conductive and/or air infiltration heat loss. 6. A post-work audit will be completed by an auditor separate from the auditor who completed the initial assessment 7. The office of Urban Assistance will randomly select a number of jobs to assess for Quality assurance Mechanical Systems Heating system work in the weatherization program is completed by an experienced HVAC/mechanical contractor. The intent is to put the client's HVAC system in good operational order for the least amount of money. This means that the work must pay for itself in future energy savings. Architectural Shell Work Architectural shell work (insulation, air-sealing, etc.) will be completed by a skilled architectural contractor, as well as those who have secured their Building Performance Institute (BPI) Residential Building Envelope Whole House Air Leakage Control Installer via the Weatherization Training Specialist Program. The applied work will help reduce future energy costs of the client and increase comfort, and health and safety of the dwelling and family. I.2 SECTION II PROGRAM ELIGIBILTY AND BENEFITS SECTION II PROGRAM ELIGIBILITY AND BENEFITS RWP Eligibility Eligibility for RWP is limited to households at or below 60% of the Annual Median Income level as specified in Exhibit RWP Income Guidelines Section II. This income test will be based on the household's income (inclusive of the owner(s) as identified on the mortgage or renter(s) as identified on the Lease Agreement) for the past 3 months which must be documented via pay check stubs. (30 ILCS 738/) Urban Weatherization Initiative Act states that weatherization services will only be provided to: 1) a family unit whose income is at or below 60% of the Annual Median Income as identified in the 2010 Census; 2) owner-occupied single family homes in the areas which have been identified by the Board of Directors that meet the income level identified via the 2010 Census; and 3) multi-family (6 units or fewer) in the areas which have been identified by the Board of Directors that meet the income level as specified via the 2010 Census. “For Sale” Status or Foreclosure A home may not be weatherized if the unit is for sale, or in the process of being sold. This would include a sign in the yard, or other public posting. If the Grantee discovers that the home is listed “For Sale” during the process of Weatherization, all work should be stopped, and the Job should be closed out. The process should be well documented with narrative and/or digital photos of a for sale sign, if applicable, and placed in the file. Additionally, a Notice to Cease Weatherization Services will be forwarded to the assigned grant manager, homeowner and/or renter. A home may not receive Weatherization services if it is in the process of foreclosure. Prioritization Applications will be based on income eligibility as identified in the Urban Weatherization Initiative Act Definition of Income For the purpose of the RWP, income is defined as including money, wages and salaries before any deductions. Income also includes regular payments from social security, railroad retirement, unemployment compensation, strike benefits from union funds, worker's compensation, veteran's payments, alimony, and military family allotments; private pensions, government employee pensions (including military retirement pay), and regular insurance or annuity payments; dividends, interest, net rental income, net royalties, periodic receipts from estates or trusts, and net gambling or lottery winnings. Note: Child support payments are considered as income. Income excludes, (1) capital gains, (2) any assets drawn down as withdrawals from a bank, (3) the sale of property, a house, or a car, (4) one-time payments from a welfare agency to a family or person who is in temporary financial difficulty, (5) tax refunds (6) gifts, (7) loans, (8) lump-sum inheritances, (9) one-time insurance payments, or (10) compensation for injury, less than $10,000.00. Income also excludes non-cash benefits, such as the employer-paid or union-paid portion of health insurance or other employee fringe II.1 benefits, food or housing received in lieu of wages, training stipends for Title V Senior programs or WIA (JTPA), and such federal noncash benefit programs as Medicare, Medicaid, Food Stamps, school lunches, and housing assistance. Note: Earned Income of dependent minors (children under 18 years of age) and college scholarships are not considered as income and are excluded. Categories of Weatherization Measures There are three common categories of weatherization measures for the Residential Weatherization Program. The three common categories are Retrofit Measures, Air Sealing Measures, and Health and Safety Measures. All measures must be placed in one of these following categories: 1. Retrofit Measures: These measures address conductive heat losses of a structure or generate heat for the structure. Any measure that produces an energy savings is a Retrofit Measure. All Retrofit Measures generate a Savings-to-Investment Ratio (SIR). The Retrofit measure MUST include all Tasks that are necessary to install that measure. An example would be that a replacement heating system would include the furnace, mounting blocks, plenum, thermostat, wiring, any transition ductwork, etc. These items would all be detailed and listed separately within a Retrofit package, but would be included in the SIR calculation. 2. Air Sealing Measures: These measures stop outside air or conditioned inside air from penetrating the thermal boundary of the home. The result of completing these measures is determined by the air sealing measurements completed with the use of a Blower Door. Air leakage estimates are used to calculate a single Air-Sealing SIR rating for the home. Because of this all air infiltration measures installed on the home are combined together to generate a single SIR value. Some examples of Air-Sealing measures would include weather stripping, caulking, foam, thresholds, door sweeps, sash locks, etc. 3. Health and Safety Measures: These measures are to be identified during a health and safety check before weatherization services are initiated in order to protect the applicant, their family, and the workers performing the weatherization services/repairs: Identification of operable smoke and carbon monoxide detectors Identification of leaking fuel supply lines; Identification of improper or ineffective Water Heater venting (such as installing a chimney liner that is NOT part of a new furnace installation); Identification of conditions that may lead to or promote biological concerns and unsanitary conditions; Identification of minor electrical repairs/upgrades that are needed before weatherization repairs can be initiated; Identification of the need to have correction of moisture and mold creating conditions when necessary to ensure the long-term stability and durability of the weatherization measures and the clients long-term health and safety (gutters and sump pumps are not allowed); and Identification of needed water heater repair. II.2 Water Heater Replacement/Health and Safety Water Heater Repair Repair work on a water heater includes the gas valve, venting, burner adjustment, burner door replacement, minor repairs, etc. The Water Heater Repair costs do NOT include the installation of a chimney liner (or Class B flue), if needed. If the chimney liner is part of a Retrofit measure for a new heating system, then the cost is included in the cost of the Retrofit. Gas lines, sediment traps, flexible connectors, temperature/pressure discharge pipes, temperature/pressure valves, or gas shut off valves are not allowed to be replaced unless they are damaged or leaking. If any of the previously mentioned items are necessary to install, their costs cannot exceed a $200 Water Heater Repair limit. RENTAL UNITS When Weatherization Services are being requested on a rented dwelling, there will be no cost assessed to the owner of the dwelling, however the owner of the residence must reside in the building per the statute. In addition, the applicant must submit a copy of the Lease Agreement, along with a written and notarized letter of authorization from the owner granting approval for a home energy audit to be completed on the property. Once the audit has been conducted and before any weatherization service is performed on the home, the Applicant must submit a second written and notarized letter of approval from the owner of the property, authorizing the Grantee to perform the work as specified via the Work Order. All authorizations must be stored in the applicant file accordingly. Multi- Family Housing Units (maximum of 6 units) As identified in the Urban Weatherization Initiative Act (30 ILCS 738), owner-occupied multi-family housing units (6 units or fewer) are eligible to receive weatherization services if occupied by income-eligible tenants. The allowable expenditures for work on multi-family housing units (up to a maximum of six units) are derived by multiplying the maximum material and labor limit ($6500.00 per unit) times the number of income-eligible units within the building. The maximum expenditure for the Site (building) is then spread equitably between all units within the building. Vacant units are to be counted as eligible units if the Landlord has signed and agreed to rent the vacant unit(s) to income eligible clients up to 30 days of the initial assessment of the property. The Landlord must show proof of deposit received from the renter in the form of a certified check, along with a signed Rental Agreement in order to have the vacant unit(s) included in the allowance. In order to weatherize an entire multi-family housing unit, at least two-thirds (66%) of the building’s units or apartments must be occupied by income-eligible tenants, unless the landlord provides a rental agreement and a deposit check from the soon to be renter stating they will occupy the residence within 30 days of the assessment. The only exception to the two-thirds (66%) rule is when the residence is a duplex. In a duplex, one unit (50%) must be income-eligible. Example: in a triplex, two units (66%) would need to be income-eligible; in a four or five unit building, three units (66%) would need to be incomeeligible; in a six unit building, four units (66%) would need to be income-eligible. II.3 Furnace Assistance As identified in the Urban Weatherization Initiative Act (30 ILCS 738) a heating unit can be replaced if it is nonrepairable and the total cost for purchase and insulation does not exceed the total maximum allowance of $6500.00. This benefit will only be available to those income eligible households whose utility services have not been disconnected. If the total cost exceeds the maximum allowable expense, no work will be completed by the RWP. The family will be referred to the LIHEAP Furnace Assistance Program that is operated through the Illinois Home Weatherization Assistance Program (IHWAP). The Furnace Assistance component will only be operated from October 1 through April 30. No furnace work will be performed on any furnace in a home that has been condemned or otherwise deemed uninhabitable by the State or any unit of local government or by any department or subdivision of the State or local government. In addition, no work will be done on any furnace in any household that is pending foreclosure sale within 90 days. A post-work audit will be conducted within 15 working days to ensure that all work was completed in a safe and effective manner. Only one furnace replacement benefit per dwelling is allowed for a period of 10 years. Agencies will need to keep an electronic file listing the address of households receiving a furnace and maintain their records for a period of 10 years. If a replacement heating system is required, a 90% plus “two pipe” (sealed combustion) system must be installed. An 80% plus system is only to be installed if the contractor has provided sufficient documentation as to why a 90% plus system could not be installed, and a waiver must be approved by the grant manger and a copy maintained in the applicant file. If an 80% plus system is installed in a location that uses a masonry chimney, a metal flue liner must also be installed. A flue liner must be installed for the water heater if a 90% system is installed, and the water heater remains as a stand-alone (orphaned) unit. The heating contractor must complete a heating system sizing calculation to ensure that a properly sized heating system is installed. Copies of these calculations are to be maintained in the client file. A Health and Safety review shall be done in conjunction with the assessment and one (1) copy will be provided to the homeowner or renter and one (1) copy will be placed in the Applicant file. If any health or safety concerns are identified, no weatherization services will be performed. This program will not pay to repair health and/or safety problems identified. The Applicant may reapply once the health and/or safety concern(s) have been properly addressed and proof of repair(s) are provided. All proof of repairs must be placed in the applicant’s file, this must include receipt of services completed and paid for. The furnace section of the Applicant client file must contain: a completed Furnace Assistance Final Inspection form a copy of the contractor’s itemized invoice II.4 for furnace replacements, a written estimate for documentation of needed repairs vs. the new furnace costs to compare and validate repairs the home ownership documentation which may include, but is not limited to: a copy of the deed; the property tax bill; a mortgage payment book coupon; an authorization statement from the executor of a blind trust, or other legal documentation on home ownership that has been filed with the County Clerk. a sizing chart for furnace replacement if an 80% plus furnace was installed, the file must contain an OEA-approved waiver documenting as to why a 90% plus system could not be installed, Any work completed exceeding the mechanical cost limits that do not have prior authorization from OEA are considered disallowed costs. the Contractor Release of Lien the Contractor Assurance & Guarantee of Work the Contractor Checklist (signed and dated by the HVAC contractor) the Assessment Worksheet the Client Information Worksheet the Furnace Assistance Rating Sheet II.5 SECTION II PROGRAM ELIGIBILITY AND BENEFITS EXHIBITS RWP Income Guidelines Mechanical Cost Waiver Form RWP INCOME ELIGIBILITY GUIDELINES Illinois Housing Development Authority 60% AMI Effective December 31, 2012 Family size 1 PERSON 2 PERSON 3 PERSON 4 PERSON Chicago $30,960 $35,340 $39,780 $44,160 East St. Louis $29,100 $33,240 $37,380 $41,500 Kankakee $26,100 $29,820 $33,540 $37,400 Peoria $28,020 $31,980 $36,000 $39,960 Rockford $25,680 $29,340 $33,000 $36,660 (for each additional family member add the following) Chicago-$4,380 East St. Louis- $4,140 Kankakee- $3,720 Peoria- $3,960 Rockford- $3,660 Residential Weatherization Program Mechanical Cost Waiver Failure to complete the Mechanical Cost Waiver in its entirety will delay the time frame for processing.

Grantees are to publicize the date, time, and location where applications will be accepted. This information must be publicized at least two (2) weeks in advance of the application acceptance period. It is expected that a minimum of 1 outreach program is sponsored by the Grantee, prior to the application period and a minimum of four (4) outreach activities that include speaking with the community providers are planned. Outreach responsibilities include, but are not limited to: Ensuring persons within the service area are notified about the program via planned presentations at a location that is accessible to the public Publishing information pertaining to the RWP in the local newspapers and other media outlets Distributing approved RWP marketing material to local churches, community providers, etc. Coordinating with and referring to other energy-related services Providing energy-related consumer education throughout the agency's service area Further, outreach is intended to let the general public know of the weatherization services offered by the Grantee. As the Residential Weatherization Program is operated on a first come first served basis and does not have a prioritization system, Grantees must develop outreach procedures that ensure the families within their service areas are aware of the Residential Weatherization Program. As such, it is important that each Grantee develop positive working relationships with those groups in the community that are in regular contact with the general population. Grantees are expected to maximize their efforts to inform potential applicants, neighborhood organizations, and local units of government about the Residential Weatherization Program. Distributing approved weatherization brochures and local agency printed information shall be done to encourage community members to apply to the program. Outreach to potential applicants shall be done on an equitable basis to all communities within the Grantee’s targeted service areas. Each Grantee is expected to maintain a visit log that documents the audience, date, and time of all outreach visits that promote the Residential Weatherization Program. Each Grantee shall prepare written materials that describe how the program operates, the application period, where applications will be accepted, the application process, along with eligibility requirements and type of income documentation that is required. III.1 SECTION IV INTAKE SECTION IV INTAKE Every Grantee must establish an intake system that will collect and secure the data needed to certify each applicant as eligible for weatherization services. The Residential Weatherization Program application is the official and only application form that is to be used. All intake services must be performed according to the instructions prescribed by the Residential Weatherization Program as identified in the Residential Weatherization Program Procedure Manual. During intake, an applicant may be deemed ineligible, pending eligibility, or eligible as detailed in Section V of the procedure manual. It must be noted that all intake and weatherization services are free of charge to the applicants. Intake responsibilities cover the following areas: General instructions The Residential Weatherization Program Application Completion of the RWP checklist Income Verification Completion of the Applicant Health and Safety Questionnaire Completion of Consent Forms General Instructions All applicants must be provided a program overview as detailed in Section I of the procedure manual. During the application process, all households must be given the opportunity to apply for the program, regardless if they do not have all the necessary information at the time of application. In the event the applicant is without all required documents, the applicant will be categorized as “pending eligibility” and be allowed a grace period of ten (10) calendar days to supply the necessary documentation. A letter specifying specific documents and any outstanding information will be given to each applicant. If the applicant does not provide the required documentation within the 10 day grace period, the application must be denied. Grantees are reminded that information received on all applicants is confidential and is obtained only for use by the Residential Weatherization Program. Grantees are hereby advised NOT to give out information about the applicant or his/her application to anyone outside of the applicant or DCEO which will be used for report purposes only. All documents received from applicants must be date stamped. Residential Weatherization Program Application Instructions: Please PRINT all responses clearly and legibly. Please note that applications are not to be completed in pencil. DO NOT USE CORRECTION FLUID TO MAKE CORRECTIONS. To make corrections, draw a horizontal line through the mistake and write corrections to the side of the box. Application Date: Enter the date the application is taken. This will be eight-digit number. The first two digits represent the month (e.g., January will be 01, February will be 02, etc.). The second two digits will represent the day of the month (01/31). The final four digits represent the calendar year. Example: February 18, 2012, will be recorded as 02/18/2012. IV.1 Grantee Name; Applicant Name and Address: Enter the Grantee Name, Applicant Name, Address, and Zip Code. Enter the Applicant Last name, First name. County/ Area: Indicate the County that the dwelling is located. Also indicate the area which the dwelling is located. Home Phone and Alternate Phone: Indicate the primary and alternate phone numbers. Dwelling Type: Indicate the type of dwelling with a check mark: Single Family Unit means a structure containing no more than one household unit. Two to Six Dwelling Unit means a structure containing 2-6 units within the dwelling Ownership: If an applicant owns his/her home, documentation must be provided by the household to verify home ownership. If the applicant rents, the landlord must supply proof of property ownership. This documentation may include a copy of the deed, property tax bill, mortgage payment book, or an authorization statement from the executor of a blind trust, etc. If the applicant rents, the landlord must provide a copy of the rental agreement These forms must be placed in the applicant’s file and a copy given or mailed to the applicant and/or landlord. Applicant must indicate appropriate category with a checkmark Own – Yes or No Rent – Yes or No Property Owner’s name and Address: List the owner’s name and address. Owner must reside in the building in order for the applicant to be eligible. List of Household Member(s): This area should contain all of the information for all household members. If there are more than 6 members in the household, you must use an additional application or supplemental sheet to record the additional household information. Total Number of Household Members: Add names of household members and enter total. IV.2 Income Verification Documents: Check all that is applicable and attach supporting documents. Family income may not exceed 60% Area Median Income for the number of residents per household. At the time of application, gross income documentation must be provided for each person in the household who has received income during the last 12 months. If a household is on a fixed income (income that does not change), it is acceptable to verify one payment as income and multiply the amount by twelve to obtain an annual amount. Examples of fixed income include: SSA and SSI VA Benefits IDHS payments (TANF, AABD, RRA) Pensions Documentation must be based on at least three months income prior to the date of the application. For example, the previous year’s tax return may not be acceptable, unless it was filed near the time that the RWP application was completed. If an applicant does not have proof of income for the full 3 months, the best and quickest way to handle this is to have the applicant go to the source of the income(s) and have the source complete an Income Statement. Social Security Administration (SSA): When using the award letter as documentation, subtract the monthly Medicare amount from the gross monthly amount to get the 30-day income. Be careful not to confuse SSA benefits with those of Supplemental Security income (SSI). Some monthly amounts may change. Unemployment: Enter the previous 30-day/3 month total of payments for unemployment. Supplemental Security Income (SSI): Enter the total of payments from SSI, excluding Medicare payments. Temporary Assistance for Needy Families (TANF): Enter the total of payments from TANF for the most previous 3 month period. Other: Enter the total of all other sources of income not listed above. The Following are Not Considered as Income: Reimbursements for vocational rehabilitation transportation and maintenance Reimbursement for other expenses incurred (such as for medical expenses) Scholarships, student living allowance, student grants, or student loans Loans Sale of property Sale of house or car Tax refunds One-time insurance payments or compensation for injury IV.3 One-time payments e.g., Death Benefits, Circuit Breaker Benefits, LIHEAP, etc. Foster Parent reimbursement (Note: Do not count children as household members) Food Stamps Job Training Partnership Act Earned Income of dependent minors (children under 18 years of age) 3 Month Household Income: Enter the previous 3 month and annual gross total of all money, wages, and salaries (before any deductionsexcluding food or rent in lieu of wages). Wages earned by child care and other odd jobs should also be entered on this line. ANNUAL INCOME: Indicate the total annual income Social Security Number: Enter the household member’s Social Security Number. Hard copy proof of SSN may include a copy of the Social Security card, a copy of a valid driver’s license that shows the Social Security Number, or any other form of government-issued identification that shows both name and number. The Department of Commerce and Economic Opportunity (DCEO) is committed to protecting the privacy of its vendors, grantees and beneficiaries of programs and services. At times, DCEO will request social security numbers (SSNs) or other personal identifying information. Federal and state laws, rules and regulations require the collection of this information for certain purposes relating to employment and/or payments for goods and services, including, but not limited to, grants. DCEO also collects confidential information for oversight and monitoring purposes. Applicant Signature: The Applicant must sign the form indicating that all information presented is accurate. If the applicant cannot read the Acknowledgement on the application, the Intake Worker is responsible for reading and explaining the information. The application must then be signed and dated by the applicant. If another person provides the information for the applicant, that person (18 years or older) shall sign the applicant’s name, then their own name and indicate their relationship to the applicant (e.g., John Jones by Mary Smith, daughter). If the person giving the information is other than an immediate household member, the applicant must give written permission for the application to be signed by the person. The applicant/signer must then enter the date. If applicants are unable to sign their name to the application and have no representative to sign for them, applicants must sign with an X. The intake staff must then initial the applicant’s X. IV.4 The intake staff must present a copy of the application to the applicant and place a copy in the applicant file.

Homeowner’s Signature________________________ Homeowner Phone # __________________________ Date________________ SECTION V DETERMINATION Section V DETERMINATION Determination of Client Eligibility Intake is the initial step in the application process which ensures that the household is eligible for weatherization services. Intake instructions require all documentation to be date-stamped based upon the date of receipt. This is imperative as it will establish the beginning of the processing timeline. At intake one of three actions may occur .The application will be deemed ineligible, pending eligibility, or eligible. If the application is deemed ineligible, a letter will be forwarded citing the reasons for ineligibility and a copy will be placed in the applicant’s file. If additional documents are required, the application will be identified as “Pending Eligibility” until all documents are submitted to the intake staff. A letter citing what documents are outstanding will be forward to the applicant and a copy placed in the applicant’s file. If it is determined that required documents are missing, the applicant must submit those documents to the intake staff within ten (10) calendar days from the date of the letter. If the information is not submitted within the required time frame, the application will be deemed ineligible, and the intake worker will forward a letter of ineligibility to the applicant within two (2) business days, while citing their ineligibility as a result of the applicant’s failure to forward the required documents. The intake worker has eight (8) calendar days to determine an applicant’s initial eligibility. Once it is determined that an applicant is eligible, the intake worker will draft a letter citing the applicant’s eligibility for the program and the next steps that will follow. After review, the intake worker will forward the letter, along with all supporting documents, to the supervisor for final eligibility determination. The supervisor must provide final eligibility determination by signing off on the eligibility letter within 48 hours of the intake worker’s initial approval. A copy of the eligibility letter must be placed in the applicant’s permanent file before being forwarded to the applicant. Please note that the final eligibility determination is for the agency's protection. By having two people review the file, it is less likely a site-visit or audit will discover ineligible clients. For this reason, final eligibility determination for each applicant must be made by the supervisor as previously stated. Determination responsibilities include the following: Reviewing the application form to ensure that it is thoroughly completed Assuring all documentation is provided with the application Intake worker will ensure all documentation provided is valid Once the intake worker provides initial application approval, the supervisor must review and approve final eligibility V.1 Work-Flow for Eligible Clients Once intake is completed within ten (10) business days, a home energy audit must be completed within ten (10) business days from the date of the final eligibility determination. The intake process and audit must be completed within thirty (30) days from the date the intake process began. Work-Flow for Pending Eligible Clients Once the intake staff is in receipt of all requested documents, she/he must determine the applicant’s eligibility with 24 hours of receipt of documents. The intake worker must then forward the eligible application to the supervisor for final eligibility determination. The supervisor must make final eligibility determination within 48 hours of receipt of the application, after which the auditor will be allowed 10 days to complete the audit. Assuring Documentation is Present The applicant has seven (7) days from the date of the notice of pending eligibility to supply the necessary documentation or the application will be denied. For this reason, it is recommended that pending files be organized by date. Based upon varying circumstances, it may be warranted that assistance be provided to the applicant, by the intake worker, in an effort to obtain the requested documentation. All efforts to assist with securing documentation must be documented and placed in the client file. When documentation has not been received within the required timeframe, the Grantee must forward written correspondence to the applicant indicating that the application has been denied weatherization funding, as a result of their failure to submit the requested information and a copy placed in the file. Verifying Household Income Information: The number of persons documented in the file as receiving acceptable types of income listed is to be verified with the application information. Determination of Unit Eligibility: In addition to determining a client's income eligibility, it is also necessary to assure proper documentation is obtained and proper procedures are followed for weatherizing various dwelling types. Prior to authorizing the work, then the grantee must follow the requirements below per dwelling type: Single Family Owner-Occupied: Dwellings shall be assisted if they are occupied by an incomeeligible owner. The owner must supply proof of property ownership. Single Family Renter-Occupied: For dwellings occupied by income-eligible renters, a rental agreement signed by the landlord is required. The weatherization process cannot move forward until the Rental Agreement is signed. V.2 NO ARCHITECTURAL WORK IS TO BE DONE ON ANY UNIT WHERE THE HEATING SYSTEM HAS BEEN DETERMINED TO BE UNSAFE. 2-6 Unit Rentals. If 50% of the 2-unit building is occupied by income-eligible renters, and the building has a common foundation, then the entire building may be weatherized. If this is the case, then the landlord must sign a rental dwelling unit agreement. If only one of the units in a 3 to 6 unit building is occupied by an income-eligible client, then the one unit shall be eligible for weatherization and treated as a single family renter-occupied unit. The “66% or greater” rule applies in the case of 2,3, 4,5, and 6-units. However, no furnace work may be done on a central heating system. NO ARCHITECTURAL WORK IS TO BE DONE ON ANY UNIT WHERE THE HEATING SYSTEM HAS BEEN DETERMINED TO BE UNSAFE. Multi-Unit Buildings. Entire multi-unit buildings (2 to 6 units) shall be assisted if: (1) more than 66% of the tenants are income-eligible for Urban Weatherization Initiative (2) the grantee has obtained written permission from the landlord; (3) the grantee has received written or email approval from their Grant Manager approving the Multi-Family Building Plan; and (4) the landlord has signed the Rental Agreement. SRO, Group Home, and Shelters. Residents of a privately owned or not-for-profit operated single room occupancy (SRO) building, group home, or shelter are not eligible for weatherization services under the Urban Weatherization Initiative. Re-determination of Eligibility If actual weatherization work has not begun on the unit within 6 MONTHS from the date eligibility determination was made, the income eligibility must be re-determined. Unless a substantial amount of information on the application has changed, a new application will not need to be completed. In this case, sign and enter this date to complete the application. If the client is over-income or otherwise determined ineligible after re-determination, the application is denied. It is not necessary to re-determine client eligibility if work has begun within the required timeframe on the mechanical system. Re-weatherization Prohibition Agencies are prohibited from weatherizing any housing unit that received Urban Weatherization Initiative assistance previously. V.3 SECTION VI URBAN WEATHERIZATION INITIATIVE: WORK AUTHORIZATION SECTION VI URABN WEATHERIZATION INITIATIVE: WORK AUTHORIZATION All Urban Weatherization Initiative contractors are required to be certified with the State of Illinois, insured, and bonded before starting on any contractual weatherization work. Client Notification The Intake Worker will forward the residential occupant a copy of the Final Eligibility Determination Letter which must detail the following: The date which the final eligibility was determined; The date which the home energy audit must be completed; The start and conclusion dates in which the weatherization work on the home must be completed; Information pertaining to the post-work audit, i.e. the date of completion and auditors name; and finally agency contact information in order for the applicant to express concerns or make inquiries regarding weatherization services being received. As previously indicated in Section 5-Determination, the Home Energy Audit must be completed within 10 days of the final eligibility determination. The weatherization work on the home must be completed by the contractor within 45 days after the award has been accepted. The Post-work Audit must be completed within 14 calendar days after the weatherization services have been completed. Multi-Family Building Approval Process Before any weatherization services are initiated, the owner of the building must provide written consent authorizing the Grantee and subcontractors permission to perform the work. This form gives the Grantee, along with the contractors, permission to complete the home energy audit, as well as the weatherization services on the property. In addition, a notarized letter from the owner stating that the owner will not raise the rent on the property for 5 years after completion of the weatherization services on the home. Prior to scheduling work on multi-family buildings, Grantees are required to obtain written approval from the Urban Weatherization Initiative Grant Manager prior to commencing weatherization services. The Grantee must complete a Multi-Family Building Plan, place a copy in the file, and submit a copy to grant manager for approval. The following information must be included in the Multi-Family Building Plan: 1. 2. 3. 4. 5. 6. 7. 8. Name of owner of the property Address of building Total number of units Apartment numbers of all income eligible units Heating system type/configuration Estimated materials and labor costs for each unit Photos of the units to be weatherized. Work that will be completed on the property. In addition, the grantee must tender copies of the final eligibility determination letter in conjunction with the Multi-Family Building Plan for approval before work commences. VI.1 Work Authorization Flow Process for Single Family Homes Work Authorization Flow Process for Multi Family Homes VI.2 Reversing Approvals and Denials The following criteria shall determine the status of the dwelling unit should a client vacate the dwelling unit after work on the unit has started, or before work on the unit has been completed: 1. If a client is a homeowner, work shall be discontinued, and the unit shall be counted as a completion. 2. If the landlord signs an agreement to rent to another low-income eligible client within thirty (30) days of vacation, and presents a new rental agreement, along with a notarized rent guarantee, work shall be continued and the unit shall be counted as a completion. 3. If the landlord refuses to sign the agreement, work shall be discontinued. Urban Weatherization Initiative: Timelines Work Authorization includes the responsibility of the Grantee to follow the required timelines as described below: Eligibility Determination: The Grantee has up to 30 CALENDAR DAYS from the date an application is received to determine eligibility and notify the client of their application status. If documentation is incomplete at time of application, the applicant has at least ten (10) CALENDAR DAYS to provide the necessary information. If the required documentation is not provided, the application will be denied. NOTE: Timeframes for eligibility determination for clients residing in Multi-family buildings is the same. Home Energy Audit: The audit for architectural, shell (basic), and mechanical systems work shall be done prior to beginning any weatherization work. It is required that both the architectural shell and mechanical systems assessments be done at the same time. Six Month Re-determination: If actual audit weatherization work (materials installed) has not begun on the unit within 6 months from the date eligibility determination was made, the income eligibility must be re-determined. Unless a substantial amount of information on the application has changed, a new application will not need to be completed. If the client is over-income or otherwise determined ineligible after re-determination, the application is denied. It is not necessary to re-determine client eligibility if work has begun within the required timeframe. Failure to re-determine the income, if more than 12 months has elapsed since work began, will result is disallowed Weatherization costs. Work Began: Under the above guidelines, actual weatherization work must begin within 6 months of the date eligibility determination was made. No work can begin on a multi-family unit building until it is determine that the cost to weatherize will not exceed $19,500 in repairs, and all required documents are forwarded to the grant manager and written approval is provided. The final costs for mechanical work must be determined before architectural work begins to avoid exceeding per unit costs maximums.

The audit monitoring will be performed by the assigned grant manager or other DCEO staff. 4 Procurement Monitoring will evaluate the Grantee’s implementation of the Procurement Policy. Procurement Monitoring will include but not be limited to; Contractor file reviews and material/labor bid survey review. This review may also include a Weatherization Material and Labor price review. If Urban Assistance determines that the procured prices are too high, those costs may be disallowed and only approved up to an acceptable cost by DCEO standards. 5 Urban Assistance’s staff will review and ensure that staff of the Grantee provides oversight to the data entry of certified payroll and conduct employee interviews to that Residential Weatherization Program Compliance is adhered to at the contractor/crew level as developed by RWP. This monitoring may also include data entry review of payroll information into any electronic systems utilized for certified payroll. The grant manager will monitor for ensuring that Davis Bacon wage compliance is maintained. VII.5 6 Lead Safe Weatherization Monitoring will be conducted to ensure compliance with mandated Lead Safe Weatherization Practices and training of such statutes. 7 EPA Lead Renovator (RRP) Compliance Monitoring will be conducted to ensure compliance with mandated EPA Lead Renovator practices and training of such statutes. Residential Weatherization Program– Monitoring Details The dwelling units inspected will be selected randomly from a list of eligible clients that will allow for a comprehensive sample of weatherization services being provided. Monitoring visits may focus on problem areas as identified in previous monitoring visit reports to ensure that prior deficiencies have been remedied. Recommendations or required corrective action will be issued to grantees based on findings identified during said monitoring visits and such requirements/recommendations will be detailed on a monitoring visit report provided to the grantee. Any measure or repair initiated by the Grantee that is not in compliance with the Residential Weatherization Initiative’s policy and procedures will result in disallowed cost. Deficiencies identified during Urban Assistance monitoring that results in Major findings or repetitious Minor findings will be considered justification for re-inspection of the dwelling. Continuous/systematic deficiencies identified by Urban Assistance will require immediate action by the respective Grantee and the development of a corrective action plan, with designated times frames to remedy identified and documented issues of non-compliance. Findings Matrix Minor Findings: All areas of noncompliance with the Residential Weatherization Program policy and procedures not considered Major will be referred to as Minor findings. Minor findings may include but are not limited to substandard work, missing attic insulation measuring sticks, incorrect documentation, etc. Minor Findings will require a response from the Grantee, detailing the corrective action taken to alleviate the deficiency identified, if specifically noted in the Monitoring Review Report. When similar Minor Findings are found on two or more consecutive Monitoring Visits, those Minor Findings will be elevated to Major Findings, and the grantee will be required to develop a Corrective Action plan, or modify one which may already in effect. Minor Findings could result in the requirement of additional training for the grantee and/or contractor personnel, or other disciplinary actions leading up to termination. VII.6 Major Findings: 1. Any of the following criteria constitutes a Major Finding; The health and safety of clients, grantee’s staff and contractor/crew staff, or the structural integrity of the building is compromised by the work completed with Residential Weatherization Program Funds. A health and safety problem is created by, exacerbated by, or not corrected by the delivery of Residential Weatherization Program’s funded services. The omission of a required procedure that addresses health and safety concerns that are within the scope of weatherization. Weatherization jobs that are paid for with Residential Weatherization Program Funds ; yet are not applied to the dwelling. Expenditure of Residential Weatherization funds for items that exceed the stated cost limits, without prior written authorization by the Grant Manager. Additional funds that exceed the cost limit specified will be considered as disallowed costs and deleted from the line item cost of Residential Weatherization or refunded to the Residential Weatherization Program. All fiscal files, records, and documentation must be revised accordingly. Poor quality workmanship that significantly affects the performance of weatherization measures. Expenditure of Residential Weatherization Program funds on Retrofit measures that are not approved under RWP, or required for mitigation of health and safety concerns. Expenditure of Residential Weatherization funds on Retrofit that were not approved and identified in the scope of work. Any action or lack of action that would threaten the integrity of the Residential Weatherization Program and/or discredit its ethical standards. A monitoring visit report from an Urban Assistance Grant Managers that contains Major Findings: Requires an immediate response from the grantee receiving the finding as defined in the Monitoring Visit Report generated by the Residential Weatherization Program. When feasible, or construed to be necessary, a corrective action plan should accompany the grantee’s response. Requires that corrective action must be taken VII.7 Could result in disallowed costs that the grantee would have to refund to Residential Weatherization Program. Could result in an increased monitoring frequency by Urban Assistance grant manager. Could result in the requirement of additional training for the grantee and/or grantee’s contractor personnel as specified by the Residential Weatherization Program. Could result in the recommendation of High Risk status or Grant Default Status for the grantee receiving the Major Finding. Subsequently, special conditions will be placed on the grantee’s grant agreement(s). Continued Major Findings may result in the termination of the grantee’s grant agreement with DCEO. High Risk Status or Grant Default Status: The occurrence of a substantial number of, or repeated, Major Findings may result in a decision by the Grant Manager to place a grantee on High Risk status or Grant Default status. If a grantee is placed on High Risk status or Grant Default Status, special conditions will be placed on the grant which will affect their ability to receive Residential Weatherization Program funds. Those special conditions will include but not be limited to additional reporting requirements as specified by the Residential Weatherization Program and a detailed corrective action plan to remedy monitoring deficiencies and limited or total restrictions on the availability of cash requests from the appropriate Residential Weatherization Program grant, or all RWP funding. If a grantee is placed on High Risk status or Grant Default Status, the grantee will be placed on probationary status for up to two years following the date of the probation period initiation. Failure to comply with the special conditions placed on the grant agreement and/or continued noncompliance or Major Findings will be grounds for termination of the grant agreement between the grantee and DCEO. After failing to comply with the Residential Weatherization Program grant conditions, or the correction of grant deficiencies, an administrative meeting will be convened between grantee and the Grant Manager. VII.8 Notwithstanding any of the above, Urban Assistance may suspend or terminate a contract without prior written notice upon a finding of substantial non-compliance or substantial breach of grant agreement. Additional Requirements 1. The Grantee will comply with all other program components outlined by Residential Weatherization Program’s policy and procedures. 2. If a materials inventory is utilized, a first-in, first-out perpetual inventory system must be used by the Grantee to track and account for all weatherization materials. The inventory should be carried as an asset on the fiscal records of the Grantee, and adjusted as used for the residential weatherization completion of an applicant’s dwelling. A physical count of all inventory, including hand tools and equipment, is to be done once per quarter to verify the accuracy of the physical count of the perpetual inventory record. This must be filed and presented to the Grant Manager during the review. 3. The Grantee will weatherize homes according to the guidelines and agreement established by the Residential Weatherization Program to ensure the highest quality of work and most efficient energy conservation measures are conducted. 4. Additional sub-contractual agreements are prohibited, with the exception of labor to install weatherization materials without the prior written approval from Urban Assistance Administrative staff. 5. The Grantee will ensure that approved bidding procedures are followed when purchasing materials and procuring labor under this work statement. These procedures are outlined by the Residential Weatherization Program. Quality Control The Grantee will ensure that services agreed upon through grant agreement with the Residential Weatherization Program are provided in a quality manner. Specific procedures to monitor review and evaluate assessments, workmanship and, audit and post-work audit will be on file for review. Production The grantee will weatherize all homes assigned for weatherization, and utilize allocated funds made available via Residential Weatherization Program for each respective RWP grant. The grantee agrees to spend all budgetary funding within the designated county as identified by the Residential Weatherization Program. VII.9 1. The Grantee will weatherize an appropriate number of homes to utilize all funds made available by each Residential Weatherization Program Grant. The grantee will ensure that funds are spent in the county to which they were allocated. 2. The Grantee will submit a production plan as specified in the awarded Grant. The production plan will provide specificities, and agreement to revise the plan on record with the Residential Weatherization Program as needed or required by RWP. Production-Related Costs 1. The Grantee will not exceed $6,500 on “Weatherization” work on any home weatherized. Costs per completed unit shall include program support costs and actual costs of materials and labor applied. 2. The mechanical costs for a weatherization unit may not exceed $2600. The Mechanical costs for a unit that contains a boiler or conversion/gravity heating system replacements may not exceed $3200. Mechanical costs for an Energy Related unit may not exceed $3,500. In certain instances such as a home with no existing ductwork, or an existing boiler system with complete radiator and pipe replacement, a case-specific cost waiver must be applied for through the Office of Energy Assistance. Expenditures in excess of the amounts listed above will result in disallowed costs. 3. The Grantee agrees not to exceed the maximum per unit costs for the weatherization which has been established in writing by the Residential Weatherization Program. Exceptions to this policy will not be honored, unless a written waiver has been obtained from the assigned grant manager. 4. Administrative funds will be earned at a final rate of the amount of the grant that was properly expended. For example: If a grantee was only able to complete 80% of a grant’s production, they would only be able to receive a total reimbursement of 80% of the administrative funds for that grant. Performance The Grantee will provide complete weatherization services to all eligible households throughout the identified service areas. This will be a critical factor in evaluating the overall performance of the Grantee under the Residential Weatherization Program. The Grantee will ensure that required efforts and provisions are made to recruit and provide weatherization services to all eligible households throughout the targeted service area. These activities of the Grantee will serve as an instrument to effectively measure overall performance of the Grantee. General Residential Weatherization Requirements 1. Under no circumstances is the Grantee to complete the Architectural portion of a home without first making certain that there are no fuel leaks are present, the heating system is operating safely and/or the water heater is properly venting. VII.10 2. No Weatherization material is to be left at the job site for the client to install. If a weatherization material cannot be installed, notation is to be made on the Work Order as to why installation was not possible. Uninstalled material is to be returned to the warehouse or vendor with a credit for the material made to the Residential Weatherization Program. 3. Weatherization waste byproducts should be remediated on a daily basis and are to be removed from the job site once the work is completed. 4. The Grantee will ensure that the Grant Manager is provided an accounting journal that has completed entries of all current negotiated/competitive prices for all materials and labor. The Accounting Journal’s entries should adhere to the following: a. Not have reference to installation of storm doors. Storm doors are not to be installed in the program. b. Reference replacement windows, doors, and storm windows as Retrofit Measures, not as Health and Safety or Air-Sealing Measures. All windows (including storm windows/inserts) must receive a positive Savings to Investment Ratio greater than a value of “1”. 5. All duct work (except duct insulation as a Retrofit) is considered an Incidental Repair Measure and a mechanical cost. 6. Switching primary fuel sources can only be done after approval in writing is provided by the assigned grant manager 7. When primary sashes (on a site-built home) are not assessed for replacement or when the window did not receive a positive SIR (greater than “1”) for replacement, the check rails of the window at the point of the sash lock shall meet and be flush. 8. This may require that the lower sash be planned on the bottom to allow the checkrails to be flush with one another at the sash lock. It is prohibited to shim and “space” sash locks. 9. If rolled metal is used for the heat barrier on attics insulated with cellulose, the barrier must be fastened securely to the attic joist in such a manner as to not allow the barrier to collapse and touch the heat source. Batt insulation may not be used as a heat barrier. All heat barriers must be anchored in such a manner as to provide a three-inch air space between the barrier and the heat producing source. 10. Duct repair refers to situations where major duct work installation is required to balance the heat delivery of the furnace. This usually occurs when a replacement furnace is installed and the existing duct work is oversized or major pieces of the duct system are missing. Duct repair includes supply and return air registers. Duct replacement with the installation of a new furnace is considered as part of the overall Retrofit measure costs. Duct installation on an existing HVAC system is considered as an Incidental Repair measure and is subject to the appropriate limits. VII.11 11. Electrical refers to the installation of electrical wiring needed to allow the installation of insulation. The installation of electrical wiring includes all junction boxes and conduit needed to complete the work. All electrical work must be completed by a certified electrician. 12. Plumbing refers to the installation or correction of plumbing problems that may cause any weatherization measure not to be installed. Plumbing also includes the repairing of the plumbing pipe if the water or sewage is backing up and creating a moisture problem for installed weatherization material. 13. Roof refers to the replacement or repair of roofing so that insulation may be installed. Limitations do apply. Please contact your assigned grant manager for prior approval. 14. Water heater work refers to no fuel leaks are present and the water heater is properly venting. 15. New furnaces installed by the Residential Weatherization Program are to have the flue gases checked for Carbon Monoxide and Oxygen after installation and the tape of the Post-test included in the client file and taped to the gas appliance. These two (2) measurements will indicate whether the new furnace is operating to manufactured specifications. The heating system efficiency and Oxygen percentages will vary depending on the individual manufacturer and system design specifications. On new heating system installations, the PMI manual is to be attached to the HVAC system, and available for inspection. Furnace filter racks are to be installed in accordance with the system’s PMI manual. 90 Plus Furnace Installations – 90 plus heating systems will be installed only as 2-pipe systems with separate exterior combustion air intake and flue gas exhaust. The Oxygen (O2) and Carbon Monoxide (CO) measurement will be taken at the flue on the outside of the house. Normally the furnace will be side-vented through the foundation of the home. If the furnace is vented through the roof and it is difficult to access or hazardous, the flue test may be omitted. When the flue has been drilled, the hole is to be sealed with high temp RTV sealant, nylon plug, or butyl-backed Adhesive tape. Standard adhesive aluminum tape is not to be used. In cases where The Oxygen and/or Carbon Monoxide measurements do not fall within the perimeters established by the manufacturer, the mechanical contractor is to correctly adjust the furnace to proper specifications. 80 Plus Furnace Installations: The Carbon Monoxide (CO) measurement will be taken at the furnace, unless the manufacturer specifies that drilling the flue will invalidate the warranty. No draft test is needed on these power vented systems. 80% furnaces may only be installed with a waiver from the assigned grant manager. Appropriate forms, documentation, and digital photos are required. The maximum material cost for the 80% furnace may not exceed $750. VII.12 SECTION VIII ASSESSMENT ASSESSMENT Assessment Overview The assessment is one of the most important steps in the weatherization process. It is the first point at which the agency enters the client's home and determines the structural condition of the home. The auditor’s job is to conduct a thorough review of the home so that the weatherization measures to be installed will save the most energy, while ensuring the health and safety of the household. During the process of conducting an audit of the home, both the architectural and the HVAC system is required to be done at the same time. Required Color Digital Photographs Digital color photos are required to be taken and placed in the Residential Weatherization Program Applicant’s file under the contractor's section. Photographs of all sides of the home, including specific photos of all windows and doors are mandatory. Photos should also document any problematic areas that the contractor must address. Color photos of any problem areas are to be attached to the work order so the contractor can review them. Digital, color photos must also be in the file for any retrofit or other measures that is assessed to be replaced. When a change order is requested by the contractor, color digital photographs are required to support those changes. The photographs must clearly document the need for change and have to be affixed to the change order with legible copies in the Applicant's file. Required Floor Print An accurate illustration of the homes footprint must be drawn by the assessor for each level of the home, including the basement and attic. All footprints must be placed in the Applicant's file under the contractor's section. All doors and windows must be identified on the foot print and labeled as specified. Un-conditioned spaces must be noted on the footprint with dashed lines (i.e. unconditioned porches, attached garage, etc). Accurate directional orientation must be labeled on the footprint as well. •The identification of doors must start with the front door of each home. Continue labeling the doors in order counter clockwise around the home. The labeling convention for doors must be in the following format: 1. The first character identifies the living level of the home 2. The second character identifies the reference item i.e. door(D) or window (W), etc. 3. The third and fourth characters will represent specific item on that living level of the home, for example: BD01= basement door 1. 1DO3= first level door 3. 2DO2 = second level door 2. The identification of windows must start with first window to the right of the front door represented as 1DO1. Continue labeling the windows in order counterclockwise around the home. VIII.1 4. The second character identifies the referenced item (i.e. door(D) or window(W), etc. 5. The third and four character represents specific item on that living level of the home. For example: BWO1=Basement window 1. 1WO6= First level window 6. 2WO2= Second level window 2. Exterior Inspection Inspect home for site drainage problems. Inspect walls for cracks, holes, or any other air sealing opportunities that may be present. Moreover, photographs must be taken of all Air Sealing opportunities on the exterior of the home ( i.e. holes in the foundation, electrical penetrations to be addressed, etc). Photographs are required for all preexisting damages to the home (i.e. damage siding, broken glass, etc). Drill an inspection hole on each side wall (under the siding) to determine if walls have existing insulation. Inspection holes may be drilled in an inconspicuous location on the inside of the home, such as a closet on an exterior wall. All inspection holes drilled on the interior of the home shall be noted and repaired by the contractor. Inspect foundation for above grade measurements. Check foundations for cracks and/or utilitiy penetrations for air sealing opportunities that may be present. Inspect crawlspace (when accessible for the exterior), if applicable, to identify retrofit, incidental repair or air sealing measures needed. For example, identify the need for rim joist or crawlspace wall insulation, vapor barrier, etc. Photographs are required for verification. Record identifying information fr0m central air conditioner and/or window air conditioning units, if applicable. Information required for central air units is make, model, age, SEER rating, size (tons). Information required for window air conditioning units is make, model, age, EER Rating, size (BTUs). it may be necessary to inquire with the homeowner regarding window air conditioners that are not in place dependent upon the current season. A photograph of the central air conditioning and/or window unit must be included in the applicant's file. Interior Inspection The objective for the interior inspection is to obtain information specific to the home's thermal performance and identify potential energy saving opportunities that can be addressed during the weatherization process. Following are the steps required for conducting an interior inspection: Make a visual inspection walk through of the home. During the walk through, the auditor must identify the thermal boundary, noting the structural integrity of the interior walls and identify obvious air sealing opportunities. Note: the thermal boundary is the separation of conditioned space from un-conditioned space. Measure the doors identified during the exterior inspection of the home that are a part of the thermal boundary. All required Air Sealing, Incidental Repair and Retrofit measures must be documented. Measure the windows identified during the exterior inspection of the home that are part of the thermal boundary. All required Air Sealing Incidental Repair and Retrofit must be documented. VIII.2 Inspect the attic, finished/unfinished, for existing insulation and determine the existing effective rvalue(s). o Unfinished attics (Open joist or Floored joist): Document the additional insulation needed in the attic based on the existing r-value. If Knob and Tube wiring exist, testing is required to determine if lines are active. Document the presence of active Knob and Tube wiring, if applicable, and the need for additional attic insulation. The attic foot print and pictures of the attic are required. This information is to be filed in the Applicant's file under the contractors section. o Finish Attics: identify the finished attic building components that make up the thermal boundary (i.e rough rafters, Outer Ceiling Joist, Kneewall, Collar Beam) and the existing insulation. Identify and document the insulation opportunities in all applicable finished attic components. if a Knob and Tube wiring exist, testing is required to determine if lines are active. Document the presence of active Knob and Tube wiring, if applicable, and the need for additional attic insulation. The attic foot print and colored photographs of the attic are required. Unfinished attics (Open joist or Floored joist): Document the additional insulation needed in the attic based on the existing r-value. If Knob and Tube wiring exist, testing is required to determine if lines are active. Document the presence of active Knob and Tube wiring, if applicable, and the need for additional attic insulation. The attic foot print and pictures of the attic are required. This information is to be filed in the Applicant's file under the contractor’s section. Finished Attics: Identify the finished attic building components that make up the thermal boundary (i.e rough rafters, Outer Ceiling Joist, Kneewall, Collar Beam) and the existing insulation. Identify and document the insulation opportunities in all applicable finished attic components. if a Knob and Tube wiring exist, testing is required to determine if lines are active. Document the presence of active Knob and Tube wiring, if applicable, and the need for additional attic insulation. The attic foot print and colored photographs of the attic are required. Inspect the basement for existing conditions (if applicable), i.e. water problems, existing insulation, etc. Document all potential air sealing incident repair(s) and/or retrofit measures. Note the obvious bypass on the foot print. Basement bypasses must be identified by hanging surveyor’s tape below the bypass location from the floor joist or near the leakage area in the rim joist. Inspect the crawl space for existing condition (if applicable and accessible), i.e. water problems, existing insulation, etc. Document all potential air sealing, incidental repair(s) and/or retrofit measures. Note the obvious bypass on the footprint. Basement bypasses must be identified by hanging surveyors tape below the bypass location from the floor joist or near the leakage area in the rim joist. Building Diagnostics Building diagnostics are crucial to the homes thermal performance. Identifying and sealing bypasses may have the biggest impact on the homeowner's energy usage. Building diagnostics also identifies potential risks to the home's occupants due to the tightness of the home and the potential indoor air quality issues that can stem from the lack of fresh air. Following are the steps required for conducting the Building diagnostics: VIII.3 A blower door test is required on every home. Run the lower door and record the CFM50 rate. A picture of the blower door set up and a picture of the manometer reading are mandatory and must be included in the applicant's file, in the appropriate section. With the blower door running, identify all bypasses that need to be addressed and the measures required to effectively seal the bypasses. Document the bypasses, again bypasses must be marked with surveyor's tape in attic sections, basements and crawlspaces. It may be necessary to go back into the attic to identify leakage areas. Pressurizing the home, changing the direction or flow of the fan, can assist in identifying attic bypass locations. Observe the home with an infrared camera as well as using smoke pencils or chemical smoke to help identify insulation deficiencies and bypass locations. Duct pressure pan readings are mandatory in homes with ductwork that extend through unconditioned spaces. Record pressure pan readings for each register. If the duct pressure pan readings are not within the allowable limits, record the measures necessary to correct the duct leakage as well as installation opportunities. Zone pressure tests must be conducted in all applicable zones such as attic, crawl space, attached garages, etc. Record the zone pressure readings, as well as the action needed in order to seal the thermal boundary between conditioned and un-conditioned spaces. Note: Conducting these tests should confirm the location of the thermal boundary. By pass locations and corrective measures must be detailed by the auditor. Health and Safety Health and safety is the number one priority in the Residential Weatherization Program. During the assessment, the auditor may encounter a variety of hazardous health and/or safety conditions. These hazardous conditions are classified as either "immediate" or "potential" depending on their severity and must identified. The Urban Weatherization Initiative will allow the use of funds to abate specific types of health and safety hazards that may exist in dwellings to be weatherized, as long as it is directly related to the weatherization of the home. The following are the steps required for identifying a home's health and safety needs: All appliances must be inspected to ensure compliance. All homes must be inspected for placement and proper operation of Carbon Monoxide detectors and smoke detectors. Inspect for proper installation of exhaust fans. All exhaust fans must be vented to the exterior of the home. Exhaust fan vents that run through un-conditioned spaces must be insulated. Measure the exhaust fan flow rate of the existing vented exhaust fans in order to determine the required ventilation for the dwelling if ASHRAE 62.2 is required. Using all pertinent data required per ASHRAE 62.2, determine the required ventilation rate for the dwelling to ensure compliance with ASHRAE 62.2. All homes must be reviewed for bulk moisture and/or mold problems. The Mold and Moisture Checklist must be completed, signed and placed in the applicant's file in the appropriate section. Any existing un-vented space heating appliances must be removed from the premises prior to weatherization services proceeding. A Hazardous Conditions Form must be completed to make the applicant/ homeowner aware of the issues. If the applicant refuses to allow the removal, the home must be deferred, which will be discussed in the next section. VIII.4 Immediate and Potentially Hazardous Conditions During the assessment, the Auditor may discover a variety of hazardous health and/or safety conditions. These hazardous conditions are classified as either "immediate" or "potential" depending on their severity. They are defined as follows: Immediate Hazard Conditions: Conditions that reasonably represent an immediate risk of harm to person or property. Potentially Hazardous Conditions: Conditions that reasonably represent a potential risk of harm to person or property. All conditions an Auditor believes constitute an immediate or potential risk to an individual or property, shall be documented on the Hazardous Conditions Form listed in the Exhibits section at the time of an audit and a copy given to the applicant and landlord, if applicable. The original copy of the Hazardous Conditions Form must be included as part of the client file. IF AN IMMEDIATE HAZARD IS DISCOVERED, NO WORK, ARCHITECTURAL OR MECHANICAL, IS TO BE DONE ON THE UNIT UNTIL THE IMMEDIATE HAZARD HAS BEEN CORRECTED! IF THE HAZARD CAN BE CORRECTED, AS AN ALLOWABLE RESIDENTIAL WEATHERIZATION PROGRAM EXPENDITURE, THE HAZARD REMEDIATION WILL TAKE PRIORITY! The following listing is examples of Immediate and Potentially Hazardous conditions. This list is not an all-inclusive list of hazards that an auditor may encounter during an assessment, but should be used as a guide for use during an audit to notify applicants and landlords, if applicable, of hazards that presently exist in a building. General Immediate Hazards 1. Single wall vent going through wall or floor 2. 3. 4. 5. 6. 7. 8. Outside vent terminating 2 foot above grade (conventional appliances) Single wall vent less than 6" from floor joist Dryers exhausting into chimney Vent connectors not vented to proper chimney Gas leaks Missing or capped/sealed Water Heater T&P valve Ambient Air C.O. reading greater than 25 PPM Water Heater Immediate Hazards 1.

Gas Ranges Immediate Hazards 1. 2. 3. 4. Connector not in same room Missing doors, panels, and drawers More than one flex connector in series CO reading in ambient air above range above 25 PPM VIII.6 Potential Hazards 1. Improper gas/air adjustment causing discoloration around burners 2. Possible gas line located behind electric range 3. Improper pipe for gas line (copper for natural gas, or galvanized water pipe) Sediment Traps Gas lines supplying gas appliances that do not leak are to be left in place without modification. When installing new gas appliances a sediment trap may be installed. Flexible Gas Line Connectors Gas lines supplying gas appliances that do not leak are to be left in place without modification. Install a flexible gas line connector when an existing connector is leaking gas. Flexible gas line connectors are not to be installed on water heaters or furnaces. Gas Line Replacement Gas lines of gas appliances that do not leak are to be left in place without modification. Replace gas lines only in cases where the gas line is leaking. When replacing gas lines use black pipe of the correct diameter to allow adequate amount of gas to appliances. Flexible gas pipe (Trac Pipe, etc.) is to be used only in crawlspace areas where installing black pipe is not feasible. Any gas line that is leaking or damaged, is considered an Immediate Hazard and must be remedied. This includes black pipe, copper, galvanized, etc. Any functional, but improper type of gas piping, such as copper used in natural gas lines, galvanized, etc. is considered a Potential Hazard. This condition should be noted on the Hazardous Condition Form and a copy of this form should be given to the client, owner of the building, and grantee. Total copper gas line replacement is not an allowable Residential Weatherization expenditure. The type of work allowed under the Residential Weatherization Program’s Health and Safety P shall include: Inspection and Testing of Combustion Appliances • Checking combustible fuel lines for leaks for all combustion appliances. This includes the heating appliance, water heater, and gas dryer. • Performing a flue gas analysis test on the heating appliance, gas stove, and water heater to determine the parts per million of carbon monoxide and ensure adequate draft in both the heating appliance and water heater vent pipes. IF A HIGH LEVEL OF CARBON MONOXIDE IS FOUND TO BE PRESENT (over 100 ppm) IN THE WATER HEATER OR FURNACE VENT, THEN THE APPLICANT SHOULD BE NOTIFIED THAT THE HOME CANNOT BE WEATHERIZED UNTIL THE WATER HEATER, OR GAS APPLIANCEIS REPAIRED OR REPLACED. AT THAT TIME, THE TESTS WILL BE RECONDUCTED AND WEATHERIZATION WILL PROCEED, IF THE CO LEVELS ARE ACCEPTABLE. Smoke Detectors At least one smoke detector will be installed on each level of the home. The costs of installing these units will be charged to Health and Safety costs. VIII.7 Smoke Detector Specifications 1. Ionization and photoelectric smoke detectors that are powered by a 9 volt battery and emit a signal when the battery is losing power are required. 2. The unit is to include a screw mounting bracket; all installation hardware is to be included. 3. The product is required to be approved by the Underwriters Laboratory. CO Detectors CO detectors shall be installed according to the manufacturer's recommendations on every job where fuel-burning appliances are present. Detectors are required to be purchased by the owner. Moisture Control Excess moisture will be controlled by implementing the following measures: 1. A visqueen ground cover is required in all accessible crawlspaces. 2. Exhaust fans in kitchens and bathrooms shall be replaced when necessary. Worker Protection The Health and Safety Plan also allows for worker protection and training that includes: 1. Provide safety training for auditors. 2. Require documentation from contractors that their workers received training on safety issues associated with weatherization. 3. Requiring material suppliers to provide Material Safety Data Sheets for their products. Fire Extinguishers The installation of Fire Extinguishers is not an allowable expenditure. Gutters and Downspouts The installation of gutters and/or downspouts is not an allowable expenditure. Gutters and downspouts can only be replaced if they are associated with the weatherization work being completed on the homes. Deferral/Walk-Away Policy The decision to defer work in a dwelling or, in extreme cases, provide no weatherization services, is regretful but necessary in some cases. This does not mean that assistance will never be available, but that work must be deferred or postponed until the problems can be resolved. Grantees are expected to pursue all reasonable options on behalf of the applicant. Deferral conditions may include but are not limited to the following: 1. The applicant has known health conditions that prohibit the installation of insulation and/or other weatherization materials. 2. The building structure or its mechanical systems, including electrical and plumbing, are in such a state of disrepair that conditions cannot be resolved in a cost effective manner. 3. The home has sewage or other sanitary problems that would further endanger the client and weatherization installers if weatherization measures were installed. VIII.8 4. 5. 6. 7. 8. 9. 10. 11 12. 13. The home has been condemned or electrical, heating, plumbing, or other equipment has been "red tagged" by local or state building officials or utilities. Moisture problems are so severe they cannot be resolved under existing allowable health and safety measures or with minor repairs. Dangerous conditions exist due to high carbon monoxide levels from combustion appliances, and cannot be resolved under existing health and safety allowable limits. The client is uncooperative, abusive, or threatening to the crew, subcontractors, auditors, inspectors, or others who must work on or visit the house. The extent and condition of lead-based paint in the house would potentially create Further health and safety hazards for the applicant or workers and could not be corrected with Weatherization. Illegal activities are being conducted in the dwelling. Client has an unvented space heater and refuses removal of the unit prior to weatherization services being conducted. Applicant refuses installation of any weatherization measures that have been approved and eligible for the Residential Weatherization Program. Any other health or safety condition present or created by, exacerbated by, and cannot be corrected by the delivery of Residential Weatherization Program funded services. When a Grantee determines that invoking the Deferral Policy is necessary, the following steps must be followed; 1. When a situation exists that causes the deferral of work, the applicant must be notified within 48 hours in writing via certified mail stating the reason(s) for invoking the Deferral Policy. In addition, a copy must be forwarded to the grant manager within 48 hours. 2. The Grantee is required to notify the applicant that work may proceed if the reason(s) for deferral are properly remedied. The resident is required to contact the Grantee upon completion of such remedies. When the matters have been mediated, the resident is required to provide proof of remediation to the Grantee before work can begin.

Notifications and Official Business Assessor’s Signature: ______________________________________________________ Date: _____________________________ THIS PAGE HAS INTENTIONALLY BEEN LEFT BLANK SECTION IX POST-WORK AUDIT SECTION IX POST-WORK AUDIT Every home weatherized must have a Post-Work Audit. The home cannot be considered complete until the post-work audit has been successfully completed. The Post-Work Audit is to be conducted as thoroughly as the initial home energy audit. Keep in mind post-work auditors not only are evaluating the quality of the work, they are also checking the quality of the original audit. Post-work auditors should look for problems that the crew or contractor may have to correct and check for the installation of materials that meet the specifications as identified in Section XIV. As part of the postwork audit process, the applicant's satisfaction survey should be given to the resident. The survey will solicit the applicant’s suggestions and/or concerns regarding the services provided. Considering the potential for vandalism, weather-related damage and safety problems, it is required that the post-work audit be done on each unit within twelve (12) working days after all weatherization work is completed. The post-work audit cannot proceed until the Work Order and support documentation for work completed has been returned to the Grantee by the contractor. As such, the contractor must submit all documentation to the grantee within 2 working days after the work is completed. The Grantee is then responsible for completing the post-work audit on the home within ten working days. To ensure an objective post-work audit is completed on every home, the staff member performing the post-work audit cannot be the same person who completed the initial Home Energy Audit. Under no circumstances, may the post-work audit be done by any person who performed the work. If it is determined during the post-work audit that the job was not completed properly, then a call-back must be ordered on the contractor, who will perform the additional work at no extra charge. The Post-Work Auditor’s job is to ensure the following: The initial Auditor has correctly evaluated each residence in accordance with the Residential Weatherization Program’s procedures. The work completed has been accomplished to a "workmanlike standard" in accordance with the quality control standards and specifications set forth by the Residential Weatherization Program. Materials applied, labor hours, and actual costs for the unit are accounted for and entered by the crew/contractor on the architectural and mechanical work orders. The completed work is checked off by the crew/contractor on the Work Order for architectural and mechanical work; and the mechanical contractor checklist is completed. A post-work efficiency test with the flue gas analyzer (if applicable to the fuel source) is conducted on the heating system, and entered on the Post-Work Audit form. A final diagnostic reading with the blower door must be taken at the time of the post-work audit and compared to the initial readings to validate the work has been completed satisfactorily. IX.1 If the fuel source is natural gas, the meter must be clocked and measured input entered on the Post-Work Audit Sheet. Evaluating the Initial Audit Reviewing the Audit Document The Post-Work Auditor must review the Home Energy Audit Form to verify the initial audit was conducted properly. Any section of the audit document not completed indicates the Initial Auditor did not complete a full audit. Notations must be made by the Post-Work Auditor on the audit document as to why a section of the audit was not completed. In cases where the Auditor did not complete a full audit of the unit, the Post-Auditor is to return the audit document to the supervisor of the initial Auditor for completion of the audit. If a Change Order is required a supplemental Change Work Order is then generated to address missing weatherization measures. The supplemental Change Work Order is to be attached to the original Work Order and becomes part of the Client File. The weatherization crew/contractor is provided the Change Work Order to complete any additional measures identified to be installed. In instances where no program funds remain to complete the needed measures the Grantee will pay for the measure with agency funds. Required Documentation Review Prior To Final Inspection The Post-Work Auditor must insure the weatherization crew/contractor has submitted all of the required documentation regarding the work completed before the post-work audit may begin. This will require the post-work auditor to complete a file review for the documents. If any of the required documents are not in the client file the crew/contractor is to be notified as the post-work audit of the home cannot be completed until the missing documentation is submitted. The required documentation and definitions by Mechanical Contractor and Architectural Crew/Contractor are listed below: Mechanical Documents Mechanical Work Order: Weatherization measures to be completed by the Mechanical Contractor are printed in list form on a “Work Order”. The Work Order provides cost estimates for each weatherization measure and summarizes total costs by category. There is an “Estimated Grand Total” at the bottom of the work order that provides an estimated total cost for the job. When estimated costs have not changed “Estimated Grand Total” becomes “Actual Grand Total”. The “Actual Grand Total” must match the grand total on the mechanical contractor's invoice. Where changes to the work order effect material and labor costs, the change work order must be reconciled to insure the “Actual Grand Total” is correct based on those changes. When a weatherization measure is completed, a checkbox is checked” by the contractor next to the measure to indicate completion. The post-work auditor also checks a box next to the measure to indicate final review. All of the “completion” and “post-work audit" checkboxes must be checked to show completion of work. IX.2 Mechanical Change Order document(s): There are certain circumstances where the mechanical contractor cannot install a weatherization measure listed on the Work Order, or a measure may need to be added. When changes to the Work Order are needed the mechanical contractor must first obtain permission to make the change by contacting the Grantee. Making changes to the Work Order is known as the “Change Work Order Process”. The process includes the completion of a “Change Work Order Form” that must be submitted to the Grantee in order to secure approval. The Grantee will place the change work order form into the applicant's file. The document will list the measure(s) subtracted or added to the Work Order with the labor and material costs for each measure stated separately. The bottom of the change work order must provide a “Grand Total” indicating the sum balance of all changes. Weatherization measures listed on change work orders must be reconciled with the invoice work order. The Work Order must reflect the information on the Change Work Order form(s). For example: If the Change Work Order subtracts, a weatherization measure from the Work Order a notation must be made on the Work Order at the location of the measure directing the reviewer to refer to the Change Work Order. With the measure deleted from the Work Order the total costs for the category in which the measure appeared would be over written with a new total cost. If a weatherization measure is added, the same procedures above are to be followed. Mechanical Invoice: The mechanical contractor is to submit an invoice summarizing, by labor and material, the cost of each measure applied to the home. The costs summaries of the invoice are to match the detail and costs summary of each measure on the Work Order. For example: The replacement furnace on the Work Order states the summary cost for furnace labor is $500.00 and summary costs for material is $950.00. The invoice would say “Installed 80,000 BTU 90% Furnace” with the labor column showing $500.00 and the material column showing $950.00. The invoice is to also show a “Grand Total” at the bottom which is to match the “Grand Total” of the mechanical Work Order. Assurance and Guarantee of Work: Labor and materials applied to client homes are guaranteed for one year starting on the final inspection date. The guarantee is valid for one year where there is no misuse by the client of weatherization services (breakage, etc.). The Assurance & Guarantee of Work document does not supersede any manufacturer warrantee for a weatherization measure guaranteed beyond the twelve month period. The Assurance and Guarantee of Work document is a required document that must be completed by the Mechanical Contractor, with the original document given to the owner of the property and a copy, or duplicate, placed in the client’s file. Release of Lien: A lien is a claim against property that must be paid before the property can be sold or transferred. The Residential Weatherization Program is a “Grant Program” that pays labor and material costs for energy conservation measures installed on client homes. Because the “Grant Program” pays labor and material costs on behalf of low income client, a lien for payment of weatherization labor and materials by the contractor is prohibited. The Release of Lien document is used to waive the right of a contractor to place a lien on the client’s home for weatherization labor and materials. The Release of Lien document is a required document that must be completed by the contractor, with the original document given to the owner of the property and a copy, or duplicate, placed in the client’s file. IX.3 Mechanical Contractor Checklist: The mechanical contractor will document the condition of the heating system with a “Contractor Checklist” by taking various readings and measurements outlined on the checklist. Corrective repairs or replacement of the heating system may be determined by the results of the readings and measurements. The Contractor Checklist must be completed and signed by the Mechanical Contractor completing the work for every heating system. Heating System Replacement Sizing Chart: To insure the mechanical contractor replaces the heating system with one that will properly heat the home a “sizing chart” will be completed. Replacement furnace sizing calculations must incorporate the architectural work to be completed on the home. The sizing chart contains a series of questions about the structure of the dwelling that will provide the mechanical contractor with an estimated BTU (British thermal unit) usage of the home. Allowable sizing charts must be scientific and answer detailed questions about the dwelling (window size, door size, or by the manufacturer of the heating system to be installed). Sizing charts written and/or drawn on note book paper are not acceptable. Architectural Documents Architectural Work Order: Weatherization measures to be completed by the Architectural Contractor/Crew are printed in list form on a “Work Order”. The Work Order provides cost estimates for each weatherization measure and summarizes total costs by category. There is an “Estimated Grand Total” at the bottom of the work order that provides an estimated total cost for the job. When estimated costs have not changed “Estimated Grand Total” becomes “Actual Grand Total”. The “Actual Grand Total” must match the grand total on the Architectural Contractor invoice. Where changes to the work order effect material and labor costs the work order must be adjusted accordingly to reflect changes and to insure the “Actual Grand Total” is correct. When a weatherization measure is completed a checkbox is “checked” by the contractor next to the measure to indicate completion. The Post-Work Auditor also checks a box next to the measure to indicate final review of completed work. Architectural Change Order document(s): There are certain circumstances where the Architectural Contractor cannot install a weatherization measure listed on the work order, or a measure needs to be added. When changes to the work order are needed the Architectural Contractor must first obtain permission to make the change by contacting the Grantee. Making changes to the work order is known as the “Change Order Process”. The process includes the completion of a “Change Order Document” that must be submitted to the grantee upon completion of the weatherization work. The grantee will place the change order document into the client file. The document will list the measure(s) subtracted or added to the work order with the labor and material costs for each measure stated separately. The bottom of the change order must provide a “Grand Total” providing the sum balance of all changes. Weatherization measures listed on Change Orders must be reconciled with the Work Order. The Work Order must reflect the information on the change order(s). For example: If the change order subtracts a weatherization measure from the work order a notation must be made on the work order at the location of the measure and identify the Grantee authorizing the change order. With the measure deleted from the work order, the total costs for the category in which the measure appeared would be adjusted accordingly to reflect changes and the new actual grand total cost. If a weatherization measure is added, the measure is to be written in at the location on the work order where it would appear. The written measure would include the description, labor and material costs, and name of the Grantee authorizing the change order. The category for the added weatherization measure would include the new total. IX.4 Architectural Invoice: The architectural contractor is to submit an invoice summarizing by category (windows, doors, etc.) the cost of labor and materials applied to the home. The cost summaries of the invoice should mirror each category on the work order. The invoice is to also show a “grand total” at the bottom which matches the “grand total” of the architectural work order. Assurance and Guarantee of Work: Labor and materials applied to the applicant is home is guaranteed for one year starting from the final date of the post-work audit. The guarantee is valid for one year where there is no misuse by the applicant of weatherization services (breakage, etc.). The Assurance & Guarantee of Work document does not supersede any manufacturer warrantee for a weatherization measure guaranteed beyond the twelve month period. The document used to provide the guarantee is the “Assurance and Guarantee of Work” document. The Assurance and Guarantee of Work document is a required document that must be completed by the Contractor, with the original document given to the owner of the property and a copy, or duplicate, placed in the applicant's file. The owner/resident must notify the grantee once they become aware of any issue(s) with the work completed within the first year. The grantee will then notify the contractor in writing of the issues noted and request repair services. This notice will be forwarded to the owner/resident and a copy placed in the file. The Urban Weatherization Initiative will take no financial responsibility in repairing homes that have been weatherized under this program. Release of Lien: A lien is a claim against property that must be paid before the property can be sold or transferred. The Weatherization Assistance Program is a “Grant Program” that pays labor and material costs for energy conservation measures installed on applicant's homes. Because the “Grant Program” pays labor and material costs on behalf of low income clients, a lien for payment of weatherization labor and materials by the contractor is prohibited. The Release of Lien document is used to waive the right of a contractor to place a lien on the applicant's home for weatherization labor and materials. The Release of Lien document is a required document that must be completed by the contractor, with the original document given to the owner of the property and a copy, or duplicate, placed in the applicant's file. Intermediate Blower Door measurement: Architectural Contractors complete work on homes that seal interior air bypass openings to the outside. Sealing the openings is known as “Air Sealing Measures”. Air Sealing Measures stop outside air or conditioned inside air from penetrating the thermal/pressure barrier of the home. The Architectural Contractor will be provided a work order that will identify the openings to be sealed. After sealing the openings the Architectural Contractor will complete at least one measurement with a blower door and manometer to determine if the air sealing work completed has been successful and to measure the reduction of outside air into the home. The measurement is a four (4) digit number known as the “Intermediate Blower Door Measurement”. The Architectural Contractor will write the four digit number on the first page of the Work Order. The Intermediate Blower Door measurement must be entered into the “Blower Door” tab of the Energy Audit before the home can be closed and reported. If the Intermediate Blower Door measurement could not be completed a notation on the first page of the Work Order explaining why will be provided by the Contractor. IX.5 Verification of Work Order Completion The Post-Work Auditor must review the work order before the post-work audit begins to insure it is completed correctly and to familiarize him/herself with the home to be inspected before arrival. If the work order indicates weatherization measures were not completed, and there is no support documentation explaining why it was not completed, return the work order to the contractor for completion of the weatherization measures. Below is a list of items that the post-work auditor must review before completing the audit: • • • • • • Have all of the completion check boxes been checked? Has the labor and material for each weatherization section been tallied? Has the total labor for the job been written at the bottom of the Work Order? Has the total material for the job been written at the bottom of the Work Order? Has a grand total for labor and material been written at the bottom of the Work Order? If a change was made to the Work Order, were a date, time and name of the Grantee or authorized agent giving approval for the change written on the Work Order? During the post-work audit, if it is determined that the work completed by the contractor was incomplete and/or there was no significant reduction in the diagnostic readings, the contractor must be called back to complete the work which they were contracted to provide at no additional cost to the Grantee or the resident. Verification of Completed work Determine whether completed work meets the specifications identified via the work order. In most cases, the job of the Post-Work Auditor will be to determine that the assessment and the weatherization measures on the Work Order and invoice have been installed correctly. In circumstances when the work is clearly unacceptable a call-back must be ordered. In circumstances where there is a question whether a completed measures meets quality control standards, document the measure in question and discuss it with the contractor completing the work. Accounting for the Work Materials applied and actual costs must all be accurately accounted for. It the responsibility of the Post-work Auditor to ensure these items are correctly and safely installed. The correct numbers and costs are to be entered on the Work Order and placed in the file. The Contractor’s invoice must be detailed and broken out by measure in the same order and format as the Work Order. These figures are the basis for reporting proper usage of Residential Weatherization Program funds. Work Order Check-off The Post-Work Audit should include checking off the items printed on the Work Order. If used correctly, verifying the items on the Work Order can help improve the quality of a contractor's work by identifying the source of any problems. Because the grant manger reviews only a percentage of the agency's work, the post-work auditor is in a much better position to detect the problem when issues reoccur. Post-Work Auditors are to check off each building section item to see if it has been completed in accordance with the work order and the Residential Weatherization Program’s Standards and Procedures. IX.6 Completing the Final Post Work Audit Form The Post-Work Auditor is to complete the post-work audit after any call-back work has been successfully completed. This form should, ideally, be completed in the presence of the applicant. Every effort must be made to fully inspect the unit and to obtain the applicant's signature on the Post-Work Audit Sheet. A copy of this form is to be left with the applicant and one placed in the applicant’s file. The Post-Work Auditor is to attach the final Flue Gas Analyzer readings to the Post-Audit Form, and a copy is to be attached to the heating system. The Post-Work Auditor is to ensure that the Intermediate and Final Blower Door readings are entered on the Post-Work Audit Form. In the event that repeated trips to the home do not result in a final sign-off, the grantee must document the efforts made and attempt to get the client’s signature via certified mail. Retain a copy of the letter sent to the applicant requesting a post-work audit date and/or signature on the Post-Work Audit Sheet. If the grantee does not receive a response from the applicant, the home may be reported as a final audit, using the date of actual inspection, or the date the response to the letter was due back to the grantee.

Both parties understand that the requested changes, as specified below, may alter the project’s price and schedule. It is also understood that any differences in estimated costs due to this change order will be accounted for in the regular payment schedule. Changes either adding or deleting material/Labor from the home will change the estimated total costs on the work order. Contractor will contact Grantee and receive authorization before making changes to work order. Contractor will calculate new costs at bottom of work order to reflex changes. Contractor will also write changes, added or subtracted, at location on work order where changes take place and enter new costs, greater or less than, those costs printed on work order. Explanation for addition or deletion of work: __________________________________________________________________________ ___________________________________________________________________________ Contractor will provide all labor and material for the following work: ___________________________________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________ Labor Costs: _________ (Add/Deduct) Material Costs: _________ (Add/ Deduct) Does Change Affect Schedule?

Partnership with the Office Urban Assistance is a business venture and must be treated as such. Therefore, records must be classified, arranged, and stored as required by the procedures set forth in this section of the manual. This section of the procedures is to provide guidance for establishing and maintaining effective filing systems and will concentrate on two areas. These areas entail required subject files and release and retention of records. Required Subject Files The subject files required are intended to maintain only the basic records needed. Subject headings under which records are to be retained include: Grant Agreement File Applicant File Ineligible Applicant Multi-Family Housing Structure Insurance Personnel Correspondence Regulations Procurement Methods Homes Previously Weatherized The Grant Agreement File is one of the most important files in the system, which contains the documents that give the Grantee it's authority to operate the Residential Weatherization program. This file must contain the following documents: A. A copy of the signed Residential Weatherization Program Grant Agreement B. A copy of any Budget Modification sheets (in chronological order) C. Quarterly Project Status Reports (Most recent report on top). D. Quarterly Financial Status Reports ( Most recent report on top). E. Quarterly Grantee Inventory Tracking Form F. Subcontract Agreement (if applicable) each agreement must be separated by a partition with subcontractor's name. G. Outreach File The original grant agreement, along with copies of the other above noted documents are to be filed with the Residential Weatherization Program. X.1 Applicant File. The Office of Urban Assistance is requiring that a standardized residential weatherization applicant file system be adhered to. This filing system will serve several purposes: 1) Standardization, 2) Continuity, and 3) File Audit Simplicity. The applicant files should be set up with a separate file folder for each residence. All file folders must be organized based upon areas served within the identified county, in alphabetical order (by applicant's name). If the applicant resides in a multi-family unit, each applicant must have a separate file folder and all folders must be stored and arranged by unit floor levels. The Grant Manager from the Office of Urban Assistance will routinely check with the designated Grantees for an organized and accurate filling system as it pertains to storing and maintaining pertinent documentation and information. Below are a list of items that will be required, yet other documents and information may be requested as warranted: Applicant Information Hazardous Materials and Pre-Audit Measurements Application Hazardous Conditions Form (if applicable) Approval/Denial Water Heater and Heating Systems Draft Test Application File Checklist Intermediate Blower Door Readings Applicant Health and Safety Questionnaire Mold & Moisture, Pressure Diagnostic Checklist Applicant Satisfaction Survey Primary Flue gas Measurements Homeowner Authorization Form Primary Blower Door Readings Income Documentation Roof Survey and Roof map (if applicable) Multi-Family Building Plan (if applicable) Post Work Audit Information Pending Eligibility Letter Post Work Audit Proof of Ownership (if applicable) Final Flue Gas Measurements Rental Agreement (if applicable) Final Blower Door Readings Utility Release Form Inspection Deficiency Report Utility Bills (Last two months) Work Authorization Other Client Documentation Contractor Information Award letter Change orders Color Digital Photos Contractor Assurance and Guarantee Form Contractor’s Bid Information Contractor Checklist Contractor’s Lien Release Contractor Inventory Tracking Copy of Certificates validating work experience Copy of cancelled checks to contractors Floor Prints: All levels of the home, including attic, basement, walls, foundations, windows, doors Invoices Proof of Insurance Scope of Work State License Work order(s): original and final if applicable At minimum, the applicant file must utilize an eight pronged classification folder with fasteners on each side. The Grantee must use adhesive labels to distinguish the various sections of each file. The fasteners must be used to attach and secure file documents. The Office of Urban Assistance will conduct file reviews on a minimum of a quarterly basis in order to monitor file structural compliance. X.2 The Applicant File must be organized as follows: EXHIBITS Section 1 2 2 3 4 DESCRIPTION Application Information Application Approval/Denial Letter Application File Checklist Applicant Health and Safety Questionnaire Homeowner Authorization Form Income Documentation Multi-Family Building Plan (if applicable) Pending Eligibility Letter Proof of Ownership (if applicable) Rental Agreement (if applicable) Utility Release Form Utility Bills (Last two months) Work Authorization Other Client Documentation Contractor Information Award Letter Change Orders Color Digital Photos Contractor's Bid information Contractor Lien Release Contractor Inventory Tracking Form Copy of certifications validating contractors work experience(BPI,LEAD,etc) Copy of Canceled Check(s) to Contractor Fiscal Detail Report Floor Prints: Attic unfinished/finished, Walls, Foundations, Windows, Doors, All Invoices Proof of Insurance Scope of Work State license Work Order(s): Original and Final (only) Contractor Assurance and Guarantee of Work Form Contractor Checklist Hazardous Materials and Pre-Audit Measurements Hazardous Conditions Form (if applicable) House Depressurization Draft Testing: Water Heater and Heating Systems Intermediate Blower Door Readings Mold & Moisture, Pressure Diagnostic Checklists Primary Flue Gas Measurements Primary Blower Door Readings Roof Survey and Roof Map (if applicable) Post-Work Audit Information Post Work Audit: Final Flue Gas Measurements Final Blower Door Readings Inspection Deficiency Report X.3 Ineligible Applicants: The grantee must maintain files containing applications and other pertinent information, including the denial letter. All ineligible applications must be stored in a manila folder and kept separate from the eligible applicant files. All applications are to be filed according to the date (month/year) which the application was deemed ineligible. All ineligible files must be stored and retained for a minimum of 4 years. Multi-Family Buildings: The system outlined below applies only to multi-family buildings completed under the “Sixty six percent (66%) or greater rule”. Agencies are required to keep a file on each building. A separate, complete application and assessment form are required for each unit. Grantees will be required to develop a building "lead file". This file must contain: A. B. C. D. Copy of the building eligibility approval or denial Applicant’s Certifications Copies of the Residential Weatherization Program energy audit; and, Individual unit files which include all documentation listed below: The following documents shall be maintained for each unit in a multi-family building: A. Client application/income documentation B. Multi-family Building Plan C. Building Post-Audit for architectural/mechanical systems D. Building ownership document E. Rental Agreement F. Applicant’s notification G. Work Orders H. Post-Work Audits I. Building owner acknowledgment of completed work Insurance: It is required that each Grantee maintains a file on insurance coverage. The file will contain at least the following information: A. B. C. D. Type of required insurance requirements Agent or company providing coverage and telephone number Policy number and date of expiration A copy of the policy Personnel: Each person employed as a part of the Residential Weatherization Program shall have a file which contains those necessary items for proper personnel management. This information must include job title and description, resume, completed application, annual evaluations, and salary information. All personnel information must be kept secured by the Grantee. RWP Correspondence: The Grantee must maintain a file that contains all correspondence for the Residential Weatherization Program. Examples of file subjects are as follow: A. Urban Assistance memorandums and other pertinent, and significant correspondence regarding the program; B. Correspondence concerning any marketing and/or media publications (i.e. all marketing information must be preapproved by the grant manager, approval for market distribution, copies of e-tear sheets). X.4 Procurement: This folder will include a listing of all services which have been procured, methodology of publication, name of all bidders, bid amounts, date of award, and name of awardee. In addition, the grantee must list by contractor all jobs completed and job number. This list must be updated on a monthly basis, as applicable. Homes Previously Weatherized: A file must be established listing the addresses of all units previously weatherized by the Residential Weatherization program. All information must be organized by area. Release and Retention of Records: There are three areas the Grantee must be aware of relative to the release and retention of records. These areas are freedom of information, the right to privacy, and record retention. Freedom of information makes it easier for individuals, legal representatives, advocacy groups, investigators, and other interested parties to gain access to information in government program files. First, the applicants have a right to see what the Grantee has on file about them. Second, anyone who files a written request can obtain certain program information that does not violate the client's right to privacy. (DCEO’S legal counsel has, in the past, interpreted this to include addresses of units weatherized.) The provision for a client’s right to privacy is also important. In accordance with the Client Privacy Act of 1974 (5 USC 552a), the Grantee may not release the client's name, phone number, social security number, income information, etc. to other entities (including service agencies), even with the best of intentions. The information retained by the Office of Urban Assistance is also confidential. The Office of Urban Assistance does not use this information for anything other than the authorized purpose. If you receive a request for information from outside groups or individuals, contact The Office of Urban Assistance prior to supplying any information. Proper record retention is paramount. Grantees are to keep program files for a minimum of four years or until that program year's audit is finally resolved to the satisfaction of DCEO. The Office of Urban Assistance may require a Grantee to retain records longer than four years by specific request. X.5 SECTION X1 INVENTORY Inventory control is a vital responsibility of the grantee and consists of several functions including the general areas of inve addition, all grantees are responsible for securing Contractor Tracking Inventory Forms in order to ensure proper purchases a Inventory Control Grantee Inventory Control The grantee is responsible for completing the Grantee Tracking Form on a quarterly basis which is to be submitted to the gran invoices must be attached to each tracking form completed.

Signature For Program Use on Review Process Name & Title Date SECTION XIII GRANT MODIFICATION PROCEDURES SECTION XIII GRANT MODIFICATION PROCEDURES If it is determined that the grant agreement requires modification in any manner, a modification form must be completed by the grantee and submitted to the grant manager for review. If it is determined that the modification being requested is within acceptable guidelines, the request will be submitted to the Board of Directors for approval or denial. If the modification is approved by the Board, the grant manager will complete the necessary steps in order to ensure the modification is executed per DCEO policy. Once the modification is executed by the grant manager, a copy of the signed modification will be forwarded to the grantee. The grantee must maintain copies of all approved modifications. If the Board of Directors is not in agreement with the Grantee's request, the grant manager will notify the grantee that their modification has been denied and the grant agreement cannot be modified. When completing a modification, the Grantee must include the following: A formal written request providing justification for the modification; Grant Agreement Modification form (found in the Welcome Package); If the grantee is submitting a budget modification, a revised budget must accompany the request, outlining the monetary changes to each cost category as applicable. The modification must be signed by the Grantee's authorized agent, usually the Executive Director Please note that no budget increase will be allowed in this grant agreement; however there are four types of modifications that can be requested by the grantee which include: Budget Scope of Work Date Extension Other All four types of modifications are discussed below: Budget Modification The Grantee is required to report fiscal information regarding expenditures for the program. The fiscal reporting requirements are detailed on the link identified in the welcome package. If it becomes necessary for the Grantee to modify the cost categories within the program budget, a budget modification is required, along with a statement of justification. When it is determined by the Grantee that a budget modification is required, they must first communicate this discovery with their grant manager. After discussion, the grant manager will direct the grantee as to whether the modification is allowable. Once this information is determined, the grantee must submit a budget modification form, along with a statement of justification to the grant manager and wait for final Board approval. No budget modifications can be made before the Board renders the final decision. Any budget modifications that were initiated prior to the Board's approval will be identified as disallowable expenses. Scope of Work A scope of work change is a change made to the original terms or conditions of the grant agreement as specified within the scope of work. Changes in the scope work can include, but are not limited to, altering the number of XIII.1 applications to be accepted; number of homes audited; number of staff employed from the training programs, areas served, number of homes repaired, etc. Date Extensions Date extensions can be initiated by the Office of Urban Assistance or can be requested by the Grantee. If the Date Extension is requested by the Grantee, they must submit a letter of justification detailing why the services outlined in the grant agreement cannot be fulfilled within the originally established time frame. Other Use this category for modifications that are being requested outside of the three mentioned above (i.e. payment provision, audit waiver, etc.). If this form of modification is requested, the grantee must attach a separate page identifying the provision requested, in addition to a written explanation supporting the modification request. It is imperative to note that no modification will be completed within 45 days prior to the conclusion of the grant period.

Cc: _________________________ (Grant Manager); Accounting * Waivers will only be approved when the Department determines that it is in the best interest of the State of Illinois Section XIV Installation and Retrofit Material Standards Section XIV Diagnostic, Architectural, and Mechanical System Standards The Urban Weatherization Initiative has incorporated standards from the Department of Energy as well as the Illinois Home Weatherization Standards Field Guide in order to complete this section. The standards presented in this section are to be utilized when completing weatherization services for the Residential Weatherization Program. Grantees must ensure that all contractors have access to this section and are aware that the postwork auditors will use these standards in order to gauge the quality of all weatherization work completed. Standards for Weatherization Materials (Appendix A to Part 440) are located in the exhibits section. Diagnostic Standards Blower Door House Set-Up Preparing the house for a blower door test involves putting the house in its heating condition with conditioned spaces open to the blower door. The house should be tested in the “as found” condition to determine its existing leakage rate. • Identify location of the thermal boundaries and house zones that are conditioned (see section “Thermal Boundary”). • Deactivate all vented combustion appliances by turning the thermostat down or the appliance off. • Prevent ashes of wood/coal burning units from entering the living space by closing/sealing doors and dampers or by cleaning out ashes. • Inspect house for loose or missing hatchways, paneling, ceiling tiles or glazing panes. Secure any items that may become dislocated during the test. • Remove one ceiling tile on suspended ceilings to relieve pressure. • Close all primary windows, self-storing storm windows, exterior doors and latch them as they normally would be found during the winter. • Open interior doors so that all indoor areas within the thermal boundary are connected to the blower door. • Do not seal intentional exhaust air openings, such as combustion appliance flues, dryer vents or exhaust fans. • Do not temporarily seal large obvious leaks such as missing or broken glass (this represents the “as found” condition of the home). • If window air-conditioning units are left in place over the heating season, conduct blower door test with the “as found condition”. If occupants remove air-conditioning units over the heating season, temporarily air-seal around units for blower door test. Basements Basements may be used as living space. Furnaces and boilers and their respective distribution systems, water heaters and washers/dryers are often located in the basement. Heat from these items as well as heat from the space above helps condition basements during the winter. Therefore, basements are usually considered XIV.1 conditioned space and basement doors should be open during the blower door test unless of one the following conditions are present (even if the basement door is generally closed during the winter): • • None of the above mentioned appliances are located in the basement, or It is clear that the occupants do not use the basement on a regular basis; for example, access to the basement is through an exterior door or hatch or through an unconditioned porch. If you’re not sure whether the basement door was open or closed during the assessment, check the work order as the assessor may have noted how the test was done. Call the assessor if necessary. Blower Door Test The blower door measures the total leakage rate of a home, indicates the potential for air leakage reduction in a home and assists in finding air leakage locations. Four leakage rate numbers are associated with the blower door test: • Building Tightness Limit (BTL), • Existing Leakage Rate, • Target Leakage Rate, and • Intermediate Leakage Rate. Manometers must be calibrated per manufacturer’s recommendations. Generally, a label affixed to the manometer indicates when the manometer is to be calibrated. Existing Leakage Rate Conduct a blower door depressurization test to determine the existing CFM50 leakage rate of home. Record the existing CFM50 leakage rate. The average existing leakage rate in Illinois’ homes prior to weatherization is about 3900 CFM. Depressurization Test A depressurization test is required (unless it is determined that a pressurization is necessary – see next section) as it is the standard test in the low-income weatherization program. If there are concerns about doing a depressurization test, perform a pressurization test or gradually depressurize the house to 50 Pa while checking the condition of the suspect areas. If, during this gradual depressurization, it is believed that further depressurization is likely to cause a problem, depressurize as much as possible and use the corrected CFM50 (done automatically when using the DG700 manometer in PR/FL@50 mode). Pressurization Test A pressurization test should be done, rather than a depressurization test, if one of the following conditions is present in the home: • Wood or coal fired-heating appliance operating, • Animal or bird feces is found in the attic that may be a health hazard, • Hole in top floor ceiling that may result in insulation being pulled into the home, XIV.2 • • • • Interior wall or ceiling finishes might be pulled down by a depressurization test, Open sump in basement, Open sewer line in the home, or Harmful pollutants could be introduced into the home by the operation of the blower door. Mold on walls is not a reason to pressurize. A depressurization test is acceptable in such cases. Can’t Reach 50 Pascals If the blower door cannot achieve -50 Pa house pressure, re-inspect the home to assure that all windows and doors are closed. If the DG700 manometer is being used, the CFM50 value shown on the right-hand display will have already been adjusted. If the older style DG3 manometer is being used, get the house pressure to the highest possible multiple of five (25, 30,35, 40, or 45 Pa). Multiply the flow rate (cfm) by the “Can’t-reach-fifty (CRF)” factor listed in Table 100-1 and record. For example, a house can only be depressurized to -25 Pa. The CFM reading is 4600. Converting to 50 Pa, the house leakage is 7360 CFM50 (4600 CFM25 x 1.6 = 7360 CFM50). Target CFM50 Rates Target CFM50 levels based on a range of existing leakage rates are shown in Table 100-2. Target CFM50 levels relate existing CFM50 leakage rates to expected post-weatherization leakage rates. The premise is that homes with high leakage rates have a potential for larger cost-effective leakage reductions than tighter dwellings. Two sets of Target CFM50 rates are shown in Table 100-2. The first set is target rates prior to the implementation of ASHRAE 62.2. Targets following the implementation of ASHRAE 62.2 are shown in the last column and are based on a 20% improvement over the existing Target Rates. Air sealing work should continue when the target has been achieved and additional air sealing opportunities are present. A concerted attempt to reach the target CFM50 must be made in every home. The most cost-effective air sealing involves addressing the largest leakage paths first and sealing leaks in the top part of the home. Confirm effectiveness of air sealing strategies by performing intermediate blower door tests. Intermediate Blower Door Test Contractors and crews are required to take, record and submit CFM50 readings to Weatherization Agencies. Known as “intermediate readings”, these readings can provide immediate feedback to those doing the air sealing work and where the leakage rate is with respect to the Target CFM50.XIV.3 Existing CFM50 0 to 1250 1251 to 1560 1561 to 2750 2751 to 4250 4251 to 5500 5501 to 7500 > 7500 Table 100-2 Target CFM50 Rates Target CFM50 Rates ASHRAE 62.2 CFM50 Rates No air leakage 80% of existing CFM50 CFM50 not to drop below 1250 72% of existing CFM50 80% of existing CFM50 64% of existing CFM50 70% of existing CFM50 56% of existing CFM50 60% of existing CFM50 48% of existing CFM50 55% of existing CFM50 44% of existing CFM50 50% of existing CFM50 40% of existing CFM50 Deferred Air Sealing Air sealing should be done in all homes; however, air sealing work may have been deferred until the following conditions are corrected. • Presence of unvented space heaters (note that no weatherization may occur in the home until unvented space heaters are removed). • Worst case depressurization limit exceeded (see section titled, “Worst Case Depressurization”), • Appliance fails spillage test-out (see section titled, “Spillage Test-Out”) • Measured drafts of combustion appliances do not meet standards under worst case conditions (see section titled, “Draft Test”), • Carbon monoxide levels exceed suggested action levels (see section 3124, “Carbon Monoxide Testing”), • Evidence of serious mold issues (an area of mold greater than 10 ft) or • The existing CFM50 leakage rate is lower than the Building Tightness Limit and . mechanical ventilation cannot be provided Post-Blower Door Test The following items should be checked prior to leaving the home following a blower door test. • Inspect all pilot lights of combustion appliances to ensure that blower door testing did not extinguish them. • Reset thermostats of heating appliances and water heaters that were turned down or off for testing. ASHRAE 62.2-2010 ASHRAE 62.2-2010, “Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings”, defines minimum requirements for mechanical and natural ventilation intended to provide acceptable indoor air quality in low-rise buildings. Low-rise buildings are defined as buildings that are three stories or less, including single-family homes. The type of ventilation system and required ventilation rate will be specified by the Weatherization Agency for each house. This information will be included on the work order. Ventilation systems and installation standards are found in Section 511, “ASHRAE 62.2-2010”. All homes weatherized must meet the requirements of ASHRAE 62.2-2010. All architectural and XIV.4 mechanical contractors should familiarize themselves with these requirements. A summary of those requirements is provided here. • Whole house continuous ventilation may be required (includes apartments) • Required base ventilation is determined by house size and number of bedrooms (Table 100-3) or by number of people living in the home (occupancy) • Required ventilation must be increased if bathroom and kitchen exhaust fans are not existing or existing exhaust flow rates are insufficient • Required ventilation may be reduced based on flow rates of existing bathroom and kitchen exhaust fans (fans must be measured to get full credit) • Required ventilation may be reduced based on the air leakage rate of home as determined by a blower door test • If the required fan size is 15 CFM or less, continuous ventilation is not required Zone Pressures The blower door can be an effective tool at finding direct leaks by depressurizing the house and looking or feeling for airflow through leaks. However, leaking air often takes a path through two surfaces that have a space, or zone, between them. These leakage sites may be difficult to find because they are in unconditioned spaces of a house. Once found, these leaks may be the largest and easiest leaks to seal.

Typical zones include attics, knee wall spaces, crawl spaces and enclosed garages. The inner boundaries of these zones are building components XIV.5 such as walls, ceilings or floors that separate these zones from the conditioned space. The outer boundaries of these zones are the walls, roofs and foundation walls that separate a zone from the outdoors. Zone-to-outside pressure readings provide information on the relative leakiness between the house and zones and are described in a later section, “Zone-to-Outside Readings”. Zone pressure testing procedures are described in a later section. The area of the “hole” between the house and the zone can then be determined by “adding a hole”. That procedure is described in the section titled “Add-a- Hole” Method. Zone-to-Outside Readings A pressure difference from the zone to the outside is measured with the blower door depressurizing the house to -50 Pa. The pressure measured between the zone and the outside can indicate the relative leakiness of the zone. Zone-to-outside readings of 0 to -25 Pa indicate that the air barrier between the living space and zone is tighter than the boundary between the zone and outside (for example, the ceiling is tighter than the roof in an unfinished attic). For zones that should be outside the thermal boundary, this is good because the air barrier is in line with the thermal barrier. However, the air barrier (ceiling) should be made tighter if the pressure reading is more negative than -5 Pa. Pressure readings more negative than -5 Pa indicate that bypasses are present in the ceiling. Bypasses must be sealed. Zone-to-outside readings of -25 Pa to -50 Pa indicate that the air barrier between the zone and outside is tighter than the air barrier between the living space and zone. For example, the crawl space foundation walls are tighter than the floor between the crawl space and conditioned area. If the crawl space foundation walls are the thermal boundary, holes in the foundation wall should be sealed until the pressure difference between the crawl space and outside is more negative than -45 Pa. Zone-to-outside readings around -25 Pa indicate that the air barrier between the zone and conditioned space and the air barrier between the zone and outside are equally leaky. Zone pressure readings unto themselves may be misleading. For example, an attic-to-outside reading of 15 Pa may seem to indicate significant bypasses. However, when tested with the “Add-a-Hole” method, the size of the hole may be small and not worth the effort to air-seal Zone Pressure Testing Procedures Utilize the following procedures for measuring zone pressures and determining leakage areas with the “Add- a-Hole” method in attics, knee wall spaces, crawl spaces and attached or tuck-under garages. Measuring Zone Pressures • Identify zones to be measured. • Set-up blower door for house air leakage test. • Set-up a hose to measure pressure in a zone. Make sure that end of hose extends beyond insulation, flooring or other obstructions in the zone. • Close opening (door, access hatch) between zone and conditioned space, taking care not to pinch hose. XIV.6 • Depressurize house to -50 Pa. • Record CFM50 of house (CFM501). • Connect hose from zone to “input” tap on manometer. Connect hose from the outside to “reference” tap on the same channel as the hose from the zone. • Record pressure of zone with reference to the outside - Z/O1. • Compare readings to those shown in Table 100-4. • Continue with the “Add-a-Hole” Method to determine cumulative hole size. Table 100-4 – Zone Pressure Readings Zone Attic Knee wall space Crawl Space Attached or tuck-under garage Basement Thermal Boundary Location Top floor ceiling and attic space Knee wall and knee wall cavity, or Knee wall space and roof Foundation wall and crawl space, or Floor between house and crawl space Between house and garage Basement foundation walls Zone Pressure Reading 0 to -5 Pa wrt outside 0 to -5 Pa wrt outside - 45 to -50 Pa wrt outside - 45 to -50 Pa wrt outside 0 to -5 Pa wrt outside 0 to -5 Pa wrt outside -45 to -50 Pa wrt outside “Add-a-Hole” Method The “Add-a Hole” Method is method to estimate the total size of all the holes and bypasses in a zone being measured. This will provide guidance towards existing opportunities for air sealing in the zone. Continue with the following procedure to determine the cumulative hole size between the house and a zone. • Turn-off blower door and partially open door or access opening between house and zone. • Turn-on blower door and record new CFM50 of house (CFM502). • Connect hose from zone to input as described above and record zone pressure (Z/O2). If the zone pressure has not changed by more than 6.0 Pa, make the opening larger. • Determine CFM50 difference (CFM502 – CFM501) • Identify multiplier from Table 100-5 based on Z/O1 and Z/O2. Use Table 100-6 if an opening was created between the zone and outside (opening an exterior crawl space hatch, for example). • Use tables 100-7 or 100-8 if measuring an attached or tuck-under garage. • Multiply CFM50 difference by multiplier to determine total leakage from zone to house. This is the total CFM50 leakage between the zone and house. • Divide total leakage by 10 to determine cumulative hole size in square inches. 2 • If relative hole size is less than 20 in (200 CFM50), no air sealing is required regardless of zone pressure reading. Zone Pressure Standards General thermal boundary (air barrier and insulation) locations and required zone pressure readings XIV.7 following weatherization work are shown in Table 100-4. If cumulative hole size is less than 20 in2 (200 CFM50), no air sealing is required regardless of zone pressure reading. Pressure-Pan Duct Test The pressure-pan test is a duct leakage diagnostic tool that is used with the blower door and digital pressure gauge to identify duct leakage to outside the pressure boundary of the home. A gasketed pan is placed over each register or grille with the air handler fan off and the blower door depressurizing the house to -50 Pa2. A pressure measurement between the duct and the room where the duct register or grille is located provides an indication of whether duct leakage to the outdoors exists. Note that you must first turn off or push the “CLEAR” button on the DG700 manometer after doing the blower door test to eliminate the “Adjusted Baseline Pressure” before taking pressure-pan readings. There is no need to use or establish a new baseline as you’re simply measuring the pressure difference between the ducts and conditioned space. This is not an issue if using the older DG3 manometer. Pressure-pan testing is required when ducts are found in: • Unconditioned spaces (some examples include attics, behind knee walls, tuck-under garages, crawl space where the floor is the thermal boundary), or • On basement return ducts when a hazardous venting or indoor air quality problem has been identified such as: worst case depressurization limits have been exceeded, poor draft with the furnace air handler operating, or elevated moisture levels in the home associated with wet basements. Pressure-pan testing is not required on ducts located in conditioned spaces. Pressure-Pan Procedures • Install blower door and set-up house for winter conditions. Open all interior doors (see house SetUp”). • Turn furnace off. Remove furnace filter and tape filter slot. Ensure that all grilles, registers, and dampers are fully open. If the pressure-pan test is being done on a house with ducts in an unconditioned space, seal supply and return air registers in the unconditioned space with tape. If the test is being done on return ducts in a basement, only seal supply registers in the basement but leave return grilles open. • Temporarily seal any outside fresh-air intakes to the duct system. • Open attics, crawl spaces that are intended to be outside of the pressure boundary (e.g. vented crawl spaces with insulation under the floor of the house), and garages as much as possible to the outside. • Close door to basement if testing ducts in basements. If possible, open a basement window or basement door to the outside. Tape the bottom of the basement door to further isolate the basement from the living space if necessary. If using DG700 manometer, turn-off to eliminate the “Adjusted Baseline Reading” from the blower door test as noted above. Turn manometer back- on; do not establish a new baseline reading. XIV.8 • Connect a hose between the pressure-pan and the input tap on the digital manometer. Leave the reference tap open. With the blower door at -50 Pa, place the pressure-pan completely over a grille or register to form a tight seal. Record the reading. Note that only one register is sealed at a time. •If a grille is too large or a supply register is difficult to access (under a kitchen cabinet, for example) or a pressure pan is not available, seal the grille or register with duct-mask tape or duct tape. Insert a pressure probe through the duct-mask tape and record reading. Remove tape following reading. Note that no air should be coming out of registers when the blower door is operating. If air is felt coming out of a register, check to ensure that air handler is not operating. Otherwise, it’s a duct leak. Pressure pan readings greater than 2.0 Pa may indicate a leak between the duct boot and subfloor/wall/ceiling rather than a breach in the duct system. Remove registers on ducts with elevated readings and inspect the boot connection. Seal boots and re-test with the pressure-pan. Pressure-Pan Standards Following weatherization work; • No more than half of the pressure-pan readings shall be higher than 4.0 Pa and • No readings shall be greater than 8.0 Pa. Duct-Induced Room Pressure Test An improperly balanced air-handling system can cause comfort, building durability and indoor air quality problems. An imbalance between the supply and return sides of the distribution can be caused by duct leakage to the outside, restricted/inadequate returns and/or the restriction of supply flow back to the main living spaces of the house. This test measures pressure differences between the main body of the house and each room, including the combustion appliance zone (or basement). This test is required as part of the worst case depressurization test (see section titled, “Measuring Worst Case Depressurization). Duct-Induced Standards Pressure differences greater than +3.0 Pa or more negative than -3.0 Pa shall be corrected. Interpreting Room Pressures Provide pressure relief when pressures are more than + or -3.0 Pa between a room and the main body of the house with the air handler operating. To estimate the amount of pressure relief, slowly open door until pressure difference drops between +3.0 Pa and -3.0 Pa. Estimate area of open door. This is the area required to provide pressure relief. Pressure relief may include undercutting the door, installing transfer grilles or installing jumper ducts. Transfer areas and ducts are sized based on the equation shown below. If grilles are being installed to correct room pressures, assume that the free ventilation area of the grille is no more than 80% of its total area. XIV.9 To calculate the finished grille size, divide the transfer area – A –by 0.8. A = Q/1.853 where: A = area in square inches Q = air flow rate (ft3/min) For example, a bedroom supply register has a flow rate of 100 CFM. The free area required for return air is 54 in2 (100/1.853 = 54). If a transfer grille is to be installed between the bedroom and hallway, the area of the grille should be at least 68 in2 (54/0.8 = 68). Exhaust Fan Flow Meter Test The exhaust fan flow meter is used to measure the air flow through bathroom exhaust fans. The flow meter is used with the digital manometer. This test must be done to confirm flow rates if exhaust fans are used to meet ASHRAE 62.2-2010. Exhaust Fan Flow Meter Procedures • Connect one end of hose to pressure tap on the flow hood. • Slide door on flow meter to either the E1, E2 or E3 position. • Connect other end of hose to input tap on left side of manometer. • Select E1, E2 or E3 on the manometer to match door opening on flow meter (see manometer instructions for selection process). • Place flow meter completely over fan forming an air- tight seal (flow meter will not work for kitchen exhaust fans). Spillage Test-Out Architectural contractors and crews are required to conduct a spillage test-out every day following completion of work. This test is to ensure that architectural work done that day has not adversely affected natural draft appliance venting. This test is only required for natural draft appliances. Note that this test is required following completion of work every day – not only at job completion. 1. Close all windows and exterior doors. Close fireplace damper. 2. Close all interior doors, including door to combustion appliance zone (CAZ)3. Leave doors to rooms with exhaust fans, such as bathrooms and kitchens, open. 3. Turn on clothes dryer. Turn on all exhaust fans, such as bathroom and kitchen exhaust fans, such that they operate at maximum speed. Do not turn on whole house fans. 4. Turn-on natural draft appliance. Test for spillage at the draft diverter or draft hood with a mirror or smoke pencil. 5. Draft must be established within three minutes. If appliance begins drafting within three minutes, the appliance passes the test. If appliance does not begin drafting within three minutes, turn-off appliance and open window if possible. Check for blocked flue or chimney. If blockage is found and removed, repeat spillage test. Appliance that fails spillage test-out may not be left in that condition. XIV.10 Architectural Standards The architectural standards include insulation and air sealing measures. Insulation retrofits are designed to reduce heat loss by conduction. Air sealing measures are designed to reduce infiltration heat loss. It is important that both conduction and infiltration measures work together. If insulation is added to an attic but bypass air sealing is not done, the effectiveness of the insulation is greatly diminished. It is critical that insulation and air sealing be done in the same building plane if the thermal boundary is to be effective. Thermal Boundary The thermal boundary separates conditioned space from unconditioned space. Typically, the thermal boundary in a house consists of the exterior walls, top floor ceiling and foundation walls. The thermal boundary is defined by the placement of insulation. The building component that separates the conditioned space from the outdoors or unconditioned space is the primary pressure boundary. In order to maximize the effectiveness of the thermal boundary, the pressure boundary must be aligned with it. That is, the pressure boundary must be part of the thermal boundary. If the insulation and air barrier are not aligned; that is, located in different building components, air can pass around or through thethermal boundary, making the insulation less effective. Basement walls are generally part of the home’s thermal boundary (see section titled, “Basements”). As such, the basement ceiling is not insulated nor are bypasses in the basement ceiling air sealed for energy savings. If it is determined that the basement walls are not part of the thermal boundary, the basement ceiling may be insulated and air sealed. Ceilings in basements with the following characteristics may be considered the thermal boundary: • Space heating and water heating appliances are not located in the basement, • It is clear that the occupants do not use the basement on a regular basis; for example, access to the basement is through an exterior door or hatch, or • Basement moisture problems that weatherization work cannot solve. The work order will define the thermal boundary of the home as determined by the assessor. In some cases, there is no right or wrong answer; only implications to the assessor’s decision. How does the home owner use the space (is it a living space even though it was not originally intended to be)? Does the budget or SIR priority permit for the ideal thermal boundary or does a concession need to be made (the assessor would like to insulate the floor above the crawl, water lines and duct work but can only afford to insulate the walls and install a ground cover)? Do we want to expand the heated area of the home (insulating the rafter cavity rather than insulating and air sealing the knee walls and outer ceiling joists, for example)? What are the costs? XIV.11 The work order will reflect these decisions. Contractors should contact the assessor to further discuss the thermal boundary definition if there are questions. Under no circumstances shall the contractor change the thermal boundary location without first discussing the implications with the assessor. Reducing Air Leakage Air leakage reduction has always been one of weatherization’s most important functions. Measures in the early days of Weatherization were limited to storm windows, storm doors, weather-stripping and caulking – all with the intention of reducing air leakage. But these measures were not always very successful. Later came the blower door and advanced air sealing, again with the intent of reducing air leakage. Air sealing was much more successful, but now it was possible to make a home too tight. Air sealing had to be balanced against making a home too tight and creating indoor air quality problems. As required by the US Department of Energy, the Illinois WAP will adopt ASHRAE 62.2, “Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings”, in July 2012. This Standard requires the installation of mechanical ventilation systems in most homes. Homes can now be made much tighter (as tight as you can get them) increasing energy savings without creating indoor air quality problems. Objectives of air leakage reduction are to: • Save energy by cutting air leakage, • Maximize insulation’s thermal resistance by reducing air movement through it, • Avoid moisture migration into building cavities, and • Increase comfort. Combustion appliances still have to vent properly, especially now that homes can be much tighter. Testing Architectural contractors are required to conduct the following two tests; • Intermediate blower door readings and • Spillage Test-Out Contractors are required to take intermediate blower door readings (see section titled, “Intermediate Blower Door Test”) to measure effectiveness of their air sealing work. It is required that contractors conduct Spillage Test-Out following work each day to ensure that spillage will not occur in the combustion appliance zones as a result of tightening the home (see section titled, “Spillage Test-Out”). Air sealing work must also be inspected to ensure that the work was done properly and the work is effective at air sealing. Depressurize the home. While in the attic, for example, air will be drawn into the home. Bypasses can be sealed while the home is being depressurized. Spray foams (both 1- and 2-part) will be drawn into the joint to help seal it. Alternately, turn the blower door around to pressurize the house (older fans have a direction switch that XIV.12 can be used to reverse the direction of air flow). Move around the attic with a smoke stick. Air will be moving up into the attic and those are the bypasses that need to be sealed. Be sure the attic hatch or door is closed to increase pressure in the home. Pressure testing the house may assist in finding air leakage locations if air sealing efforts are not effective, particularly in attics, knee wall cavities and attached or tuck-under garages. Sealing Bypasses Bypasses are holes and gaps in the thermal boundary that connect conditioned space with unconditioned space. The effort worth expending to seal a bypass depends primarily on its size and location. Bypasses will be found between the conditioned space and attic, conditioned space and crawl space and conditioned space and attached garages. Seal larger bypass openings first to achieve larger air leakage reductions. There will be cases where sealing an important bypass won’t necessarily reduce air leakage. For example, a chaseway in a plumbing wall tightly sealed from the house but very leaky to the attic acts as an insulation bypass without actually leaking air between the house and the attic. Even though the house air leakage may not be reduced, the attic insulation performance will improve after this attic bypass is sealed. It is always preferable to use strong air-barrier materials like plywood or gypsum board to seal bypasses. These materials should be attached with mechanical and/or adhesive bonds. Strong materials with strong bonds are best practice because air barriers must be able to resist severe wind pressures. When bypasses are not easily accessible, blow dense-packed cellulose insulation into surrounding cavities so that the cellulose will resist airflow and clog cracks between buildings. All bypasses are to be sealed prior to insulating except where dense-packed cellulose is also being used to seal bypasses. •Joist spaces under knee walls in finished attic areas: Connect knee wall air barriers on two floors by creating a rigid seal under the knee wall in one of two ways. Install minimum 1inch thick rigid foam board insulation blocks between ceiling joists. The perimeter of the foam blocks should be sealed with two-part foam. Tightly fill garbage bags or empty cellulose bags with cellulose or fiberglass; stuff between ceiling joists under knee wall and seal perimeter with two-part foam. •Kitchen or bathroom interior soffits: Seal the top of the soffit with plywood, gypsum board or rigid foam board insulation; fasten and seal to ceiling joists and soffit framing with two-part spray foam. •Two-level attics in split-level houses: Seal the wall cavity with a rigid material fastened to studs and wall material, or block stud cavity with scrap batt insulation and cover with 2-part spray foam (Figures 200-4 & 200-5), or Tightly fill garbage bags or empty cellulose bags with cellulose or fiberglass; stuff in wall cavity and seal perimeter with two-part spray foam. •Tops and bottoms of balloon framed interior partition wall cavities, missing top plates: Seal with rigid barrier, like ¼ inch plywood, gypsum board or rigid foam board insulation and caulk or foam to surround materials, or Block stud cavity with scrap batt insulation and cover with 2-part spray foam, or tightly fill garbage bags or empty cellulose bags with ceullulose or fiberglass; stuff in wall cavity and seal perimeter with two-part spray foam. Figure 200-4: Stud cavity sealed with 2- part spray foam Figure 200-5: Study cavity blocked with batt insulation and sealed with 2-part spray foam •Fur cavity in masonry buildings: Seal cavity with two-part foam around perimeter of attic/roof cavity. •Chimney passing through attic floor: Seal chimney and fireplace bypasses with sheet metal (minimum 26 gauge thickness) and seal to chimney or flue and ceiling structure with high temperature sealant or chimney cement. This requirement does not apply to chimneys that are no longer used and have been permanently sealed with concrete both at the vent connector to the chimney and at the top of the chimney. •Soil stacks, plumbing vents, open plumbing walls: Seal joints with two-part foam or caulk. If joint is too large, stuff with fiberglass insulation or seal with rigid foam board and foam over the top (Figure 200-7). Figure 200-7: Plumbing wall cavity sealed with foam board and 2-part spray foam •Housings of existing exhaust fans and recessed lights: Caulk joints where housing comes in contact with the ceiling (see “Attic Insulation Standards” for boxing and air sealing around recess lights and exhaust fan housings1). •Duct boots and registers: Caulk, foam or use butyl or foilback tape to seal joint between duct boot or registers and ceiling, wall, or floor finish if ducts are located in attic, crawl space or attached or tuck-under garage. •Wiring and conduit penetrations: Seal joint with caulk or foam. Figure 200-8: Duct chase sealed with foam board and 2-part spray foam •Duct chases: If chase opening is large, seal with rigid barrier such as plywood, gypsum board or rigid foam board and seal to ducts and ceiling materials (Figure 200-8). Smaller openings may be foamed or stuffed and caulked. •Joists between floors: Air seal perimeter of building at band joist areas with dense pack cellulose or fiberglass. •Bathtubs and shower stalls: Seal from crawl space or basement in one of two ways: Seal with two-part foam or rigid material for larger openings. Cover opening with gypsum board. Cut hole and dense-pack cavity. Seal hole and gypsum board to surrounding framing materials with two-part foam (Figure 200-9). XIV.15 Figure 200-9: Cavity beneath bathtub sealed with gypsum board and dense- packed with cellulose. •Attic hatches and stairwell drops: See section titled, “Attic Access Hatches”. •Other openings in the air barrier: Seal with rigid material, two-part foam, one- part foam or caulk depending upon size of opening. Bypass Sealing Materials Materials used to seal air leakage sites must be nearly impermeable to air movement as possible and form a continuous, nonporous surface over the opening being sealed. All materials must meet CFR440 specifications. Spray Foams Spray foams are either 1-part (sealant contained in one canister) or 2-part (chemicals contained in two canisters and mixed at the gun). 1-part foam is generally low or nonexpanding. 2-part foam may expand 3 to 1. MSD sheets and manufacturer’s instructions must be closely followed to ensure safety. Provide notification to the client of plans to use two-part spray foam. Provide ventilation as necessary to prevent or dilute fumes that may get inside the home. Figure 200-10 1-Part Foam (Figure 200-10) 1-part foam dispensed through plastic nozzles is not permitted. 1-part foam must be installed with a foam gun. Surface areas to be foamed must be cleaned of dust and debris with a rag. Surface areas to be foamed must be misted with water, particularly in cooler temperatures when humidity levels are low. Spray foam must be installed when the ambient temperature is between 40oF o and 100 F, unless spray foam manufacturer recommends other temperatures. Bead size should be no more than 2 inches. 1-part foam should have a Flame Spread rating of 25 or less. XIV.16 February 2013 2 -Part Foam 2-part spray foam should be installed when the ambient temperature is between 60oF and 90oF, unless spray foam manufacturer recommends other temperatures. Spray foam canisters should be brought to 70oF to 80oF before use. Surfaces to be foamed should be cleaned of debris. Should be used on gaps 2 inches or larger. 2-part foam should have a Flame Spread rating of 25 or less. Caulks/Sealants Caulk should be applied according to the manufacturer’s instructions. Caulk should be applied to a smooth, clean, dry surface. It should always be applied in a continuous bead and free of voids, with a smooth and neat appearance. Excess caulk should be removed before it cures. All openings 3/8 inch to 7/8 inch wide should be filled to within ½ inch of the surface with an appropriate packing material specifically manufactured as a packing material prior to caulking. All packing material should be compatible with the type of caulk used. Latex/Acrylic/Silicone Hybrids – must conform to ASTM C834 Acrylic (solvent type), chlorosulfonated polyethylene – must conform to F.S. TT-S- 00230C Butyl Rubber – must conform to F.S. TT-S-001657 Packing Materials Packing materials used to fill gaps too large for caulks or sealants to seal properly must be flexible closed cell or otherwise nonporous materials that will not absorb moisture and will remain flexible at low temperatures. Packing materials include flexible polyurethane, oakum, butyl rod or similar foam rod stock. Fiberglass is not to be used as an air sealing material, but may be used to stuff larger openings as a backer material with spray foam applied over the top of it. Tops of open wall cavities may also be stuffed with fiberglass which will be dense-packed with insulation. Air Barrier Materials The following air barrier materials shall be used for the following conditions: Polyethylene Should have a minimum thickness of 6 mil and be used as an interior barrier material when moisture must be kept out of the conditioned space. Spun olefin (Tyvek, Typar, etc) Spun olefin membrane air infiltration barrier should be used when moisture must escape from the conditioned space. These materials are not recommended for use in a location where they remain cool for most of the year, such as the floor above the crawl space or basement ceiling. Water vapor will not move through these materials if they are at or below the dew point temperature. XIV.17 February 2013 Wood or wood composites Wood or wood composites should be used where flame retardant characteristics are not important. When exposed to moisture or weather, all raw exposed wood must be an exterior grade material and primed on all sides. Gypsum board Gypsum board should be used in interior applications where excessive moisture is not a problem and where flame retardant abilities are important. Rigid foam board insulation Air sealing materials such as rigid foam board must be sealed in place with caulk or spray foam to make it air tight. Polystyrene shall conform to ASTM C576. Polyurethane and polyisocyanurate with foil facing shall conform to F.S. HH-1. Metal flashing Metal flashing should be used when high temperature or high moisture is a factor. General Air Sealing The following general infiltration items are done as air sealing measures when identified with the blower door. • Joints in sill plate (mud sill) and around utility openings in siding and foundation shall be sealed in an appropriate manner. When a space between two metal surfaces is to be sealed, only a butyl or silicone caulk shall be used. Cracks between two masonry surfaces shall be sealed with cement patching compound or mortar mix. If the opening is deeper than 3/8 inch, follow procedures described above. • Interior joints shall be caulked. These joints include where baseboard, crown molding and/or casing meet the wall/ceiling/floor surfaces. Gaps around mounted or recessed light fixtures and ventilation fans shall be caulked. Cover gap between the chimney and structural members (chaseways) in the basement/crawl space with a heat resistant material (flashing, gypsum board, etc.) and seal with a compatible sealant. Attic Insulation Safety Comply with fire and electrical safety procedures before insulating. • Recessed light fixtures must be enclosed with gypsum board to prevent overheating and/or fire. Provide a minimum 3 inch clearance between the box and the sides of the fixture. The box should be constructed to a height that will be 4 inches above the installed insulation. Cover the box with gypsum board and seal to the sides of the box. The box is not to be covered with insulation. If there is insufficient clearance to install a box 4 inches higher than the insulation, do not cover the box and use an appropriate barrier to keep the insulation 3 inches away from the fixture. XIV.18 February 2013 • • • • • • • • • • • If recessed lights are certified as Insulation Contact (IC rated) and airtight, they may have insulation installed directly over them. The blower door should be utilized to test the air seal of the light. Many times, the light fixture itself still needs to be air-sealed around the perimeter base where it meets the ceiling. Existing bathroom exhaust fans do not have to be enclosed as described above unless the fans include a heat lamp and/or have incandescent lamps. New bathroom exhaust fans installed by the Weatherization Program must be rated such that they may be covered with insulation. Seal bypasses around chimneys and metal flues with 26 gauge galvanized metal sealed with high temperature caulk to chimney or vent and surrounding framing materials. Vertical metal used as a barrier around heat producing devices or chimneys must be fastened securely to attic joists in such a manner as to not allow the barrier to collapse when insulation is installed. Clearance of insulation from attic furnaces must be provided in accordance with the governing code. Ventilated insulation shields should be installed around wood-stove manufactured chimneys. Install insulation beneath active knob-and-tube maintaining a one-inch air space between insulation and wiring. Alternately, non-metallic channels or barriers should be installed to maintain minimum one- inch air space alongside of knob-and-tube wiring. Frayed wiring must be repaired before adding insulation. Wiring splices must be enclosed in metal or plastic electrical boxes, fitted with cover plates. Closed electrical junction boxes may be covered with insulation, if appropriately marked. The perimeter of attic fans should be dammed with 1 inch thick nominal common lumber, plywood, metal shielding or minimum 1 inch thick foam board. OSHA-approved breather masks must be worn when blowing insulation. Attic Insulation Preparation Bypasses Air leakage and convection can significantly degrade the thermal resistance of attic insulation. All attic bypasses as previously described must be sealed before attic insulation is installed. Where existing attic insulation is present, consider pressurizing the house with the blower door to help identify attic bypass locations (see section titled, “Testing”). Roof Leaks All roof leaks must be repaired before insulating attic. If roof leaks cannot be repaired, contact the Weatherization Agency. Exhaust Fans All kitchen and bath fans currently venting into the attic must be equipped with backdraft dampers and vented outdoors through roof or eave fascia boards. Appropriate exterior termination kits such as wall caps, roof jacks and eave mounted vents shall also XIV.19 February 2013 be installed if not present. Fans without operating dampers should be repaired or the fan should be replaced with an ENERGY STAR rated fan. For additional information regarding bathroom exhaust fans and exhaust fan duct installation, see sections 511, “ASHRAE 62.2” and 513, “Exhaust Fan Ducts”. Top Plates Existing batt insulation over top plates is not to be compressed with scrap wood or gypsum board. Compressed or ineffective insulation over top plates is to be replaced. Eliminate wind washing through insulation where soffit venting exists. Block cavity over top plate to prevent blown insulation from falling into soffit and to maximize insulation over top plates. Cavity may be blocked with two-part spray foam, rolled fiberglass insulation or other rigid materials. Mechanically fasten eave chutes between foam or blocking and roof sheathing to maintain ventilation passageway. Chutes or blocking material is not to compress insulation. In rafter cavities where a chute is not installed, ensure that cavity is blocked with a rigid barrier as described above to prevent over-spill into the soffit area. Where possible, place eave chutes in every rafter cavity that is vented. Chutes must be long enough to extend above the level of the finished insulation Unfinished Attics Blowing Attic Insulation It is recommended that blown insulation be used instead of batt insulation whenever possible because blown insulation forms a seamless blanket. Attic insulation shall achieve a total R-value of 49 or the maximum amount with an SIR greater than 1.0 on the work order. Insulation shall be installed to a uniform depth according to manufacturers’ specifications for proper coverage (bags per square foot ratio) to attain the desired R-value at settled density. Contractor shall install attic insulation markers throughout the attic area to ensure that insulation is installed to both a uniform and proper depth. At a minimum, one marker shall be installed for every 300 ft2 throughout the attic. Markers shall be affixed to trusses or joists with the numbers a minimum 1 inch in height. Markers shall face such that they can be read from the attic access opening. Cellulose, blown rock wool or blown fiberglass insulation may be used to insulate unfinished attics. If cellulose insulation is used, it must be treated with boric acid which is used as a fire retardant (termed “borate only”). Blown fiberglass may be used, but note that the R-value begins to decrease significantly when the attic temperature drops below 30oF2 and be reduced by half when the attic XIV.20 February 2013 temperature is -8oF3. The loss of R-value is due to establishment of convective air currents in the insulation. This is not a problem with cellulose insulation or fiberglass batt insulation. Do not blow loose-fill insulation tight against roof deck over top plates. Cellulose should not be used where it may come in contact with exposed metal roofing. Dense pack all attic cavities, such as slopes, window bays, flat roofs and attics if not accessible for other installation methods. Install blown cellulose to 3.50 to 4.00 lbs/ft3. Access these areas by drilling or removing the fascia board and tube filling each cavity. Ventilation is not needed when dense packing flat roofs. Floored Attics Insulation shall not be blown more than 3 feet in any direction. Do not insulate cavity if live knob-and-tube wiring is present beneath attic flooring. Flooring should be removed at bypass locations for proper air sealing before insulation is installed. Insulation should completely fill the floor cavity. Install blown cellulose to 3.50 to 4.00 lbs/ft3. Flooring boards that have been removed are to be re-installed. With owner permission, flooring boards may be drilled and the cavity filled with blown insulation. Entry holes are to be sealed with plastic or wood plugs. Insulation may be blown over flooring with client’s permission. Blowing insulation over the flooring may be done in addition to blowing the floor cavity – not in lieu of blowing the floor cavity. Batt Insulation Batt insulation must be installed in such a manner to ensure proper fit between ceiling joists. There must be no voids or gaps between batts or between batts and ceiling joists. Insulation must fill joist cavity and provide uniform and complete coverage. If insulation has vapor barrier backing, the vapor barrier shall be toward heated space. When insulation with vapor barrier is installed over existing insulation, the vapor barrier shall either be removed or slashed. Cathedral Ceilings Damaged ceiling areas must be repaired before insulating. Contact Weatherization Agency if ceiling cannot be repaired. Do not insulate cathedral ceiling cavities that contain active knob and tube wiring and have not been tested for safety, thermal bypasses, open electrical boxes, blocking or recessed lighting fixtures. Access to rafter cavities in cathedral ceilings may be gained through the soffit/fascia or interior ceiling. Top and bottom of open rafter cavities shall be blocked with fiberglass or other blocking material. Dense pack cavities with cellulose insulation installed to a density between 3.50 to 4.00 lbs/ft3. Blown fiberglass is not recommended as it does not restrict the movement of air through it. Interior access holes shall be plugged and sealed such that they can be painted by the client. XIV.21 February 2013 Attic ventilation is not needed when dense packing cathedral ceilings Attic Access Hatches Install permanent blocking around the attic access hatch. Use rigid materials such as plywood that will support the weight of a person when accessing the attic. The barrier’s purpose is to prevent loose-fill insulation from falling out of the attic when the attic hatch is opened. Attic hatches installed during weatherization should be large enough for a person to pass through and allow for a thorough inspection of the attic. Openings must be at least 4 square feet and at least 20 inches in width or length. An insulated box shall be built and installed over retractable attic stairways. Hatches to attics shall be insulated to a minimum R30 with foam board insulation – hatches are not to be insulated with batt insulation. Blocking around attic hatch shall also be insulated. Attic insulation blown against and to the top of the blocking will suffice. Foam board may also be used to insulate the blocking if the attic insulation does not insulate to the top of the blocking. Weatherstrip, other than peel-&-stick foam, shall be used to seal the attic hatch. Latches, sash locks, gate hooks or two ½ inch thick pieces of gypsum board attached to the hatch are to be used to provide positive closure. Attic hatches must not be permanently sealed. If attic is accessed by a stairwell and a standard vertical door, dense-pack cellulose insulation should be blown into walls of the stairwell leading to passage door of the unheated attic. Install threshold or door sweep and weatherstrip door. Dense-pack cellulose insulation should also be blown into the cavity beneath the stair treads and risers. Determine if blocking exists to stop insulation from filling other areas by mistake when planning to insulate walls and stairway. Finished Attics The finished attic consists of five sections: • Exterior finished attic walls (end walls of finished attic) • Collar beams (above finished attic) • Sloped roof (where wall/roof finish is installed directly to roof rafters) • Knee walls (between finished attic and unconditioned attic space) • Outer ceiling joists (between knee wall and top plate of exterior wall) Attic bypasses shall be sealed before insulating. Exterior Finished Attic Walls Insulate exterior finished attic walls per section 214, “Wall Insulation”. Collar Beams & Outer Ceiling Joists Insulate collar beams and outer ceiling joists per section 2133, “Unfinished Attics”. XIV.22 February 2013 Sloped Roof (roof rafters) Sloped roofs (roof rafters) shall be tightly stuffed with fiberglass or some other stuffing material at either the top or the bottom of each run. Where possible, insulate sloped roof with dense pack cellulose installed to density of 3.50 to 4.00 lbs/ft3. If the sloped areas have existing fiberglass insulation, the top and the bottom of each cavity may be sealed and the cavity insulated with dense-pack cellulose. Knee Walls Open knee wall cavities may be insulated in one of four manners. One method may be used for closed cavity knee walls. • Open Cavity – Single Batt • Open Cavity – Double Batt • Open Cavity – Spray Foam • Open Cavity – Dense Packed • Closed Cavity Knee Wall Knee walls may also be within the conditioned space. If so, roof rafters shall be insulated rather than the knee walls. See “Knee Wall within Conditioned Space”. Open Cavity – Single Batt Insulate knee walls with maximum R-value as allowed by stud cavity depth. Extend batt insulation down to bottom plate of knee wall. Ensure that joist cavity beneath knee wall has been air sealed (see section titled, “Sealing Bypasses”). Insulation shall fit snugly between the studs. Batt insulation should be installed with the kraft paper installed towards the conditioned space. Batt insulation installed with fibers exposed to the knee wall cavity shall be covered with an air barrier material to prevent convective looping within the insulation and to prevent fiberglass exposure. House wrap material, “belly patch” or ½ inch insulated foam sheathing may be used to cover the insulation. Open Cavity –Double Batt Knee wall insulation R-value may be increased with the addition of another layer of batt insulation. • Install first layer of batt insulation as described above but with the kraft paper facing out towards the knee wall cavity. • Secure insulation by stapling the flanges to the face of the knee wall studs – no inset stapling. • Install second layer of faced batt insulation horizontal to the first layer of insulation. Kraft paper should face towards the knee wall. Secure second layer of insulation by face stapling insulation flanges to the knee wall studs. • Enclose exposed fibers of insulation with a house wrap air barrier as described above. Open Cavity – Spray Foam XIV.23 February 2013 Install closed-cell spray foam to back side of knee wall finish. Insulation shall be a minimum 3 inches thick (R18). An air barrier over the insulation is not required. However, insulation shall be covered with a fired-rated material if required by local code. Open Cavity - Dense Packed Close-in knee wall studs with house wrap material, “belly-patch” or ½ inch insulated foam sheathing using plastic-ring head nails. Spacenails no more than 3 inches apart. Secure material to top and bottom of knee wall to keep insulation in knee wall. If necessary, install additional horizontal or vertical strapping to secure material to studs prior to dense packing. Polyethylene or similar vapor barrier material shall not be used for knee wall enclosure. Cut holes in knee wall material and insulate with dense pack cellulose (3.5-4.0 lbs/ft3). Closed Cavity - Knee Wall Insulate closed cavity knee walls per section titled, “Wall Insulation”. Knee Wall within Conditioned Space Insulate rafter cavity with maximum R-value as allowed by rafter cavity depth when space behind the knee wall is considered part of the conditioned space. The attic floor cavity over the top plate must be air sealed and insulated to connect the thermal boundary from the sidewalls to the roof .Use rigid foam board or 2-part spray foam insulation. Knee Wall Hatches The access should be properly framed, be as wide as the knee wall stud cavity and be 20 inches high. The access cover should be a durable, rigid material and securely attached with appropriate hardware. Access hatch should be weatherstripped with something other than peel-&-stick foam. Hatches should be insulated to the same R-value as the knee walls with a minimum of R-value of 13. Batt or foam board insulation may be used. Window casing may be used as interior trim around hatch opening. Joints in the casing should be caulked prior to painting. Existing knee wall access hatches should be weatherstripped (no peel-&-stick foam) and insulated with a minimum of R13 batt or insulated foam board. A new access cover of a durable rigid material should be installed if necessary. Attic Venting Installing attic ventilation or increasing attic ventilation is an optional measure and is left to the discretion of the Weatherization Agency. There are very few reasons to install attic ventilation. The actual color of the roofing medium or shingles has the most impact on solar heat gain or reflection. The focus should be on controlling indoor relative humidity issues and sealing attic bypasses rather than calculating vent area and determining vent locations. If attic vents are included as part of an overall attic air sealing/insulation strategy, the following guidelines are to be met: Vent devices are not to permit rain or snow to enter the attic. Ridge vents are not to be installed on hip rafters. The structural integrity of a roof system should not be compromised for the sake of XIV.24 February 2013 installing attic ventilation. Venting in an attic does not make it acceptable to terminate bathroom, kitchen or dryer vents in the attic. If roof vents must be installed, an effort is to be made to install them on the least visible roof surface. Note that the installation of attic vents may be called for on the work order if an attic fan is present and there are insufficient vents for make-up air when the fan is operating. Existing Vents Ensure that existing vents are not blocked, crushed or otherwise obstructed. If the net free ventilation area of existing vents is not known, assume that it is half the area of the vent opening. New Vents If attic ventilation is to be installed, the vents shall be installed so there are equal amounts of low intake vents through soffit or eaves and higher exit vents on the roof. All separate attic spaces are to be crossventilated with one inlet and one outlet vent. Low/High Venting Low (intake) vents should be placed at a minimum of 12 inches above the finished level of attic insulation. Eave chutes or baffles should be provided over top plates where soffit and other low vents could cause blowing of loose fill insulation. High (exhaust) vents should be installed as close to the roof peak as possible in conjunction with lower intake vents. If eave vents are not practical, other vents should be installed low on the roof. Consideration should be given to maximizing cross ventilation. Vents should be installed in accordance with manufacturers’ instructions and sealed with an appropriate sealant. Vents should be installed in a manner to prevent the entrance of snow, rain, insects and rodents. Soffit Vents Soffit vent products specifically designed for this purpose shall be used. Soffit vents should be installed with the louvers facing toward the house. Vents may be nailed or screwed to the soffit. Open area between eave chutes or baffles and the top plate must be blocked with a material, such as rolled fiberglass or two-part foam, to prevent spillage of loose fill insulation into the soffit area and potential blockage of the soffit vents. Gable Vents Gable end vents shall be installed as high in the gable end as possible and above the level of the attic insulation. Existing gable vents should be boxed if insulation comes up to the bottom of the vent. Framing members are not be cut or removed if gable vents are placed over them. Vent openings must be neatly cut. The vent must be installed with nails or screws. Framing must be provided for the vent if there is no sheathing behind the siding. The perimeter of the vent must be properly caulked to prevent water entry. A gable vent used as an attic access must be attached by screws and easily removable. If gable vents are prone to wind driven rain or snow entry, exterior baffles shall be installed. Roof Vents Roof vents should never be installed on a roof that is in poor condition. Roof vents are not to be installed over rafters. Vent openings must be neatly cut with close tolerance to ensure a proper fit. High-mounted vents must be installed as high on the roof as practical. Vents should be tucked under shingles as much as possible and may be either fastened with shingle nails and tarred with roofing cement or nailed with neoprene-washer nails to ensure a leak-free installation. Surfacemounted roof vents are not allowed. XIV.25 February 2013 Turbine vents may only be used as exhaust vents, i.e., in conjunction with soffit, gable or roof vents. Ridge Vents Pre-fabricated aluminum ridge vents are not permitted. Only ridge vents that can be capped with shingles are to be installed. Manufacturer’s installation recommendations shall be followed, especially with regards to the presence of a ridge board and terminating cuts from end walls and hip and ridge intersections. Roof shingles and sheathing shall be cut without cutting roof rafters. Ridge cap shingles shall be installed according to shingle manufacturer’s instructions. Attic Insulation Certificate Contractors installing blown-in insulation must permanently fasten to the roof side of the attic access (or other accessible location specified by the Weatherization Agency) a signed certificate that attests to the company name, date installed, insulation brand name, R-value added, square footage, thermal resistance chart, conformance to federal specifications and the number of bags installed in the attic. Attic insulation markers shall be placed in locations throughout the attic such that insulation depth and uniformity of coverage can be inspected. At a minimum, one marker shall be installed for every 300 ft2 throughout the attic. Markers shall be affixed to trusses or joists with the numbers a minimum 1 inch in height. Markers shall face such that they can be read from the attic access opening. Wall Insulation Wall Insulation Preparation Inspect walls for evidence of moisture damage. If existing condition of the siding, sheathing or interior wall finish indicates an existing moisture problem, contact Weatherization Agency. • • • • • • • • • • • • Inspect indoor areas on exterior walls to assure that they are strong enough to withstand the application process. Contact Weatherization Agency if problems are found on walls that would prevent sidewall insulation from being installed. Inspect wall cavities for active knob-and-tube wiring. Wall cavities that contain active knob-and-tube wiring are not to be insulated. Gaps in external window trim and other areas that may leak water into the wall must be sealed. Seal interior openings from which insulation may escape, such as pocket doors, balloon framing and unbacked cabinets, soffits, and closets. Remove siding and drill through sheathing. If siding cannot be removed, contact Weatherization Agency. Asbestos siding may be removed. Decision to remove asbestos siding should be made on a home by home basis considering condition of siding. Precautions shall be taken so as not to damage siding. Asbestos siding should never be cut or drilled. If possible, insulate walls from the interior (see next bullet point). Insulation may be installed from the interior after written approval from the homeowner is obtained by the Weatherization Agency. Interior holes drilled for insulation must be finished and returned to condition as close to original as possible. Wall cavities must be probed to identify fire blocking, diagonal bracing, and other obstacles. Drill additional holes as necessary to ensure complete coverage. Pulley wells no longer used for window operation must be packed with insulation. Holes may be drilled through the jamb and sealed with plugs following installation of insulation. Dense-Packed Wall Insulation - Cellulose • Contractors and crews installing dense-packed cellulose wall insulation must be certified. • Install insulation in accordance with the manufacturer’s recommended application procedures. • Drill minimum two- to three-inch diameter holes to access stud cavities. Avoid drilling holes in vicinity of electrical outlets and switches. February 2013 • • • • • • • • Dense-packed wall insulation is best installed using a blower equipped with separate controls for air and material feed. The recommended insulation blower takeoff pressure should be at least 3.5 pounds per square inch at the exhaust port (96 inches of water column). Cellulose insulation must be blown to a minimum of 3.50 pounds per cubic foot density. This minimum density translates into just over one pound per square foot in a two-by-four wall cavity. Blowing cellulose insulation this densely requires a fill- tube. An eight-foot cavity should hold a minimum of 10 pounds of insulation. The fill tube should be 1 inch or 1 ¼ inch inside diameter tubing with the appropriate stiffness for the job and outdoor temperature. Fill-tubes should be marked with one-foot intervals to verify the correct penetration of the tube into the wall. Except as previously noted, fill all wall cavities. In some cases wall cavities close to critical framing junctures will take more insulation to plug and fill, which is often necessary in order to assure the proper air sealing of the house. All wall cavities shall be completely filled with insulation leaving no voids. Cut additional holes above or below stud cavity obstructions if necessary to fill cavity. Seal the holes with expandable foam or stuff tightly with fiberglass and cover with sheathing tape. Cover the hole with adhesive backed roofing paper, such as “ice & water shield”. Attach with minimum two staples to hold in place. Two-hole method If the interior wall finish is too weak for dense-pack installation, the two-hole method is permitted only if approval is received in advance of the work from the Weatherization Agency. Examples of weak interior finish include plaster and lath in poor condition, drywall that is less than 1/2” thick and in poor condition and wall paneling used as the interior finish. • Drill 2 one-inch diameter holes into each stud cavity. • Holes are to be located no more than 2 feet between the top plate and the top holes; 2.5 feet between the bottom plate and bottom holes. • Examine wall cavity with wire probes or steel tape to determine location of cavities around window and door areas. • Insulation to be installed in accordance with manufacturer’s recommended application procedures. • All wall cavities shall be completely filled with insulation leaving no voids. • All wall cavities around windows and doors are to be filled with insulation. Dense-Packed Wall Insulation – Fiberglass • Contractors and crews installing dense-packed fiberglass wall insulation must be certified to do so by the insulation manufacturer. • Access to wood frame sidewalls shall be per section 2141, “Wall Insulation Preparation”. • Install insulation in accordance with the manufacturer’s recommended XIV.27 February 2013 • • • • • application procedures. Dense-packed fiberglass wall insulation must be installed to a density of 2.25 pounds per cubic foot density. One 30 pound bag should fill 5 typical 2” x 4” x 8’ stud cavities to achieve this density. Drill minimum two- to three- inch diameter holes to access stud cavities. Avoid drilling holes in vicinity of electrical outlets and switches. The fill tube should be 1 inch or 1 ¼ inch inside diameter tubing with the appropriate stiffness for the job and outdoor temperature. Cut additional holes above or below stud cavity obstructions if necessary to fill cavity. Seal holes with tapered wood plugs. Seal the plug to sheathing to maintain water seal integrity with caulk or other suitable patching material. Injection Foam • • • • • • Contractors and crews installing injection foam wall insulation must be certified to do so by the insulation manufacturer. Access to wood frame sidewalls shall be per section 2141, “Wall Insulation Preparation”. Install insulation in accordance with the manufacturer’s recommended application procedures. Wall cavities shall be completely filled with no voids or gaps. Walls with existing batt insulation may be insulated with injection foam. Seal holes with plastic, foam or wood plugs. Seal the plug to sheathing to maintain water seal integrity with caulk or other suitable patching material. Band joist Insulation The band joist is the area between floors in a multi-story home. The band joist should be included as part of a sidewall insulation retrofit. Only those parts of these floor cavities that border the exterior must be insulated. In platform-framed buildings, these cavities must be accessed from the rim or band joists. In balloon framed buildings, these cavities are usually open to the walls, allowing access from the rim or band joists and also from the wall cavities above or below these floor cavities. The R-value of the insulation in these floor cavities must be at least equal to the R-value of the insulation installed in the adjacent wall cavities. Follow “Preparation” guidelines as described in section titled, “Wall Insulation Preparation”. Pay particular attention to location of light fixtures, exhaust fans, wiring and ductwork located in ceilings between floors. • • • Remove exterior finish material as described above in section titled, “Wall Insulation Preparation”. Drill 2 inch or 2-1/2 inch diameter holes to access each cavity between ceiling joists. Insert hose nozzle in cavity. Reduce air setting and raise flow on the hopper. Spray insulation into cavity. The objective is to create an “insulation plug” in the ceiling cavity usually within 3 feet to 4 feet from the band joist. Alternately, a 90o nozzle may be inserted into the cavity. An “insulation plug” will be created closer to the band joist by spraying insulation up against the subfloor. XIV.28 February 2013 Joist cavities on the remaining two sides of the home (where joists are parallel to band joist) should be completely filled with insulation. Insert rigid fill tube half the width of the cavity. Pack the joist cavity with insulation. Open-Cavity Wall Insulation Batt insulation must be cut to the exact length of the cavity. Each wall cavity should be completely filled with batt insulation. • If possible, use unfaced friction-fit batt insulation. Fluff to fill entire wall cavity. • Staple faced insulation to outside face of studs - no inset stapling. • Split batt around wiring rather than letting the wiring bunch the batt to one side of the cavity. • Insulate behind and around obstacles with scrap pieces of batt or spray foam before installing batt. • Install vapor retarder if required. Vapor barrier shall have a perm rating less than one on the warm in winter side of the insulation. Vapor retarder should be well fastened at all seams and edges. • Installed fiberglass insulation exposed to the interior living space must be covered with minimum 1/2-inch drywall or other material that has an ASTM flame spread rating of 25 or less. Completion of Wall Insulation Ensure that no insulation dust or debris have been left in or around the house. Duct system shall be inspected to assure that ducts are free of insulation. Turn on air handler and look for signs of insulation. Provide information on the wall insulation application levels (R-value, quantity of insulation, etc.) required by the certificate of insulation to be given to the client. Crawl Space Insulation The following items are required regardless of the location of the crawl space thermal boundary. • An effective ground moisture barrier must be present or one should be installed as part of weatherization. See section 2154, “Ground Moisture Barrier.” • Exhaust fans that vent into a crawl space must be ducted to the outside before crawl space insulation is installed. See section 513, “Exhaust Fan Ducts”. Crawl Space Foundation Insulation Crawl space foundation walls are not to be insulated unless existing crawl space moisture problems can be corrected. Contact the Weatherization Agency if existing moisture problems are found. Foundation wall insulation shall be a minimum R10 and should extend from the top of the foundation wall down to the crawl space floor. Extruded polystyrene and polyisocyanurate insulation are the most appropriate insulation types for flat concrete or concrete block walls. For rubble masonry walls, three-inch or six-inch thick, vinyl- XIV.29 February 2013 faced, metal-building insulation may be used. Two-part foam is also an option for insulating foundation walls and care must be taken to assure that the proper thickness is obtained. Fiberglass batts are not to be used for foundation wall insulation. Concrete block walls foundation walls may also be insulated with injection foam. Injection foam insulation shall have a minimum R-value of 4.4 per inch. Access to block cores shall be gained by drilling through mortar joints or through cores at the top of the foundation wall. Cores shall be completely filled with insulation. Contractors and crews installing injection foam insulation in concrete block walls must be. No additional foundation wall insulation is required if injection foam insulation is used. • • • • • • • • • Existing foundation vents are to be sealed. If foundation vents cannot be sealed, contact the Grantee. Foundation wall insulation is not to be installed unless the crawl space vents can be sealed. Air sealing the foundation wall is to be completed before foundation insulation is installed. A ground air-moisture barrier shall be installed that runs up the foundation walls at least 6 inches. The barrier shall be sealed to the foundation walls with an appropriate sealant. See section titled, “Ground Moisture Barrier.” Insulation should be attached to the entire wall surface with appropriate fasteners. Install insulation with no significant voids or edge gaps. All foundation insulation must be covered with a material that has an ASTM flame spread rating of 25 or less. FSK paper or 1/8 inch masonite meet this requirement. Vinyl facing on the metal fiberglass insulation also meets this requirement. If heating system is located in crawl space or combustion air is drawn from the crawl space, precautions must be taken to assure that adequate combustion air is available see section titled, “Combustion Air”. Consideration should be given to insulating the floor above the crawl space if a combustion appliance is located within the crawl space or if combustion cannot be drawn directly from the exterior. Exposed pipes and ducts are to be insulated if combustion air is provided to a heating system located in the crawl space. Exhaust fans or dryer vents that terminate in a crawl space must be ducted to the outside before insulating the foundation wall (see section titled, “Exhaust Fan Ducts”). Crawl Space Floor Insulation Floors above crawl spaces may be insulated if they form the thermal boundary. All appropriate measures shall be taken to establish an effective air barrier at the floor, to prevent air from passing through or around the insulation (see section titled, “Sealing Bypasses”). XIV.30 February 2013 • As the floor above the crawl space is the thermal boundary, foundation vents may be ignored except where required to provide combustion air to combustion appliances located in the crawl space. If combustion appliances are located in the crawl space, vent sizes shall be checked to assure adequate combustion air supply (see section titled, “Combustion Air”). • Insulation must contact subfloor to prevent convection above the insulation. Crawl space floor joist cavities may be insulated in one of two manners. • Batt insulation • Spray foam Batt Insulation Batt insulation used to insulate floor joist cavity should be the maximum R-value structurally allowable by the floor framing. Unfaced batt insulation is not allowed. Batt insulation must be securely fastened to framing with insulation hangers or other supporting material. Friction fitting or stapling of floor insulation are not appropriate methods. The following methods are acceptable. Wood lath and galvanized nails may be used to hold the insulation in place with a maximum spacing of 18 inches on center. Twine used to hold the insulation in place must be made of polypropylene, nylon or polyester with a breaking strength of at least 150 lbs and 12 inch maximum spacing between anchor points on the same joist. Wire used to hold the insulation must be zinc coated, stainless or similar corrosive resistant material with a minimum diameter of .035”. Wire must be spaced no more than 18 inches apart. Supports and anchors must be zinc coated, stainless steel or similar corrosion resistant material. Wire hangers may also be used if spaced no more than 18 inches on center and have a minimum thickness of .090 inches. The hanger ends must penetrate the floor joist at least ½ inch. Insulation supports shall not compress insulation by more than one inch. Insulation shall be fitted tightly around cross bracing and other obstructions. Batt insulation shall be installed with the facing placed up towards the floor sheathing Insulation shall be installed without voids or edge gaps. Exposed pipes and ducts must be insulated. Install a ground air-moisture barrier that runs up the foundation walls at least six inches. See section titled, “Ground Moisture Barrier.” XIV.31 February 2013 Spray foam Two-part spray foam insulation may be used to insulate the floor. Spray foam insulation must provide a minimum 3 inches (R18) against the floor deck. A minimum of 1 inch spray foam must encapsulate (sides and bottom) the floor joists and cross bracing or blocking. All members of open web floor joists shall also be encapsulated with a minimum of 1 inch foam. Spray foam insulation shall be covered with a fire rated material if required by local building code or by insulation manufacturer. Crawl Space Access Crawl space access hatches from conditioned areas should be weatherstripped and insulated to a minimum of R10. Peel-&-stick weatherstrip is not permitted to be used on crawl space hatches. Access covers must be easily removable for entrance into the crawl space. Outside access hatch shall be securely attached to foundation wall and insulated to minimum R10 if foundation walls form the thermal boundary. Positive closure (latch, sash locks, gate hooks, etc) shall be installed to provide substantially airtight closure. Ground Moisture Barrier Ground moisture barriers are required regardless of the crawl space thermal boundary location. Crawl space moisture can lead to condensation, mold and rot. Air passing through the soil can contain radon and pesticides. Covering the ground with an airtight moisture barrier establishes an air barrier and seals out moisture and soil gases. Ground moisture barriers should be minimum 6 mil polyethylene. Complete or partial coverage of ground moisture barriers will depend on the accessibility and working conditions in the space. If the entire crawl space floor is not accessible, cover as much as possible. • Ground moisture barriers must meet tear and puncture resistance standard ASTM D703. • Cover the ground completely with a ground moisture barrier without voids or gaps. • Extend air-moisture barrier up foundation wall a minimum of six inches. Seal ground moisture barrier to foundation wall with acoustical sealant, 2-part spray foam or other effective adhesive. Furring strips can be used to further secure ground cover to foundation wall. • Seal ground moisture barrier to foundation before installing insulation. • Overlap ground moisture barrier at least 6 inches and seal seam with acoustical sealant or 3M #8086 builders’ tape or equivalent. • Seal the ground moisture barrier to concrete footings with acoustical sealant or other effective adhesive. • Duct tape may also be used to temporarily seal the ground cover to the foundation wall and to seal joints between sheets. Embed the duct tape in duct mastic assuring that the mastic extends a minimum of 3 inches beyond the edge of the duct tape. Duct tape by itself may not be used to seal ground cover to foundation walls or joints between sheets. XIV.32 February 2013 Crawl Space Ventilation Installing crawl space vents is a non-allowable weatherization measure, unless needed to provide adequate combustion air to combustion heating appliance located there. If combustion air to the heating appliance is taken from the crawl space, see product manufacturer’s instructions for correct combustion air intake size. See section titled, “Combustion Air”, for additional information. Crawl space ventilation will not solve typical moisture problems found in crawl spaces. The source of the moisture must be identified and, if possible, corrected. Vents in crawl spaces with the foundation wall being the thermal barrier may be sealed with rigid insulation. Vents should not be sealed in crawl spaces with heating appliances unless adequate provisions for combustion air are provided. Vents may be installed in crawl spaces that have combustion heating systems if there are no vents or if the vents are not properly sized for combustion air. Vents should be non-operable and the client should be informed that the vents are to remain open. Basement Insulation Basement wall insulation should be a minimum R10. Basement foundation insulation must be covered with a material that has an ASTM flame spread rating of 25 or less (such as ½ inch gypsum board). Basement walls may be insulated with rigid foam board insulation or batt insulation. Insulation should be continuous from the top of the basement wall down to the basement floor. Rigid Foam Board Insulation • Rigid foam board insulation may be installed directly to the basement wall with mechanical fasteners and insulation compatible adhesives. • Joints and seams in the insulation should be sealed with sheathing tape to form an air seal. • A continuous bead of sealant should be used to seal the top and base of the insulation board to the foundation. • Sealant should also be used to seal the insulation to foundation around windows and doors. • Foil-faced rigid insulation may be exposed as the foil may have an ASTM flame spread rating of 25 – check with insulation manufacturer. • Unfaced extruded or expanded polystyrene must be covered with a material that has an ASTM rating of 25 or less. Vertical edges of the insulation may be routed to accept a 1 inch x 2 inch or 1 inch x 3 inch furring strip. The furring strips may be used to help secure XIV.33 February 2013 the insulation to the basement wall with power driven masonry nails. An acceptable flame spread material such as gypsum board or FSK7 paper may be attached to the furring strips. • Wood furring strips and gypsum board (if used) shall be held off the basement floor by a minimum 1 inch to prevent capillary action from the basement floor. Batt Insulation • 3 inch or 6 inch thick, vinyl-faced (both sides), metal-building fiberglass insulation sometimes referred to as “basement blanket” or “perimeter wrap” may be used. The insulation is installed horizontally along the wall and attached to furring strips. The vinyl facing meets the flame spread rating. • Window and door openings should be furred-out. The insulation should be attached and sealed with sheathing tape. Joints between pieces of the insulation should also be sealed with sheathing tape. • Note that condensation may occur on the basement walls with this technique if the insulation is not well sealed and the basement is subject to high moisture loads. Rim Joist Insulation Penetrations in rim joist must be sealed before insulating. Two-part spray foam is recommended for air sealing and insulating the rim joist. Rigid foam board or vinyl faced building insulation (vinyl on both sides) may also be used, but the insulation must be foamed in place to provide an air seal. Kraft and foilfaced batt insulation are not permitted (Figure 200-50) unless used in combination with two-part spray foam (see section titled, “Two-Part Spray Foam”). Unfaced batt insulation shall not be used for any rim joist application. Joist cavities that are parallel to the foundation wall may be sealed and blown with wall insulation unless moisture is present. Stud cavities in balloon framed homes must be air sealed before insulating the rim joist. Two-Part Spray Foam Provide minimum R6 (1 inch thick) with spray foam. Foam shall make a good seal between the subfloor and rim joist and between the rim joist and sill plate. Spray foam shall also extend down past the sill plate to foundation wall. Faced batt insulation may be installed over the two-part spray foam to increase the R-value of the rim joist. The International Residential Code (IRC) allows the exposed use of spray foam at rim joists (i.e., without a 15-minute thermal barrier such as drywall), as long as the thickness is less than 3-¼” (see R314.5.11). XIV.34 February 2013 High density (closed cell, 2 PCF) spray foams were approved in the 2003 IRC, and low density (open cell, 0.5 PCF) foams were approved in the 2009 IRC, as well as any intermediate densities. Rigid Foam Insulation Provide a minimum R10 rigid insulation. Insulation board should be placed firmly against rim joist. Insulation should be cut to fit tightly between floor joists and between subfloor and sill plate. Perimeter of insulation should be caulked or foamed to the floor joists, subfloor and sill plate. Both extruded polystyrene and foil-faced polyisocyanurate may be used. Vinyl Faced Building Insulation Insulate rim joist with minimum R19 insulation with vapor barrier facing the warm-in-winter side of the space. Building insulation should be cut slightly oversized for each rim joist cavity so as to form a snug fit (be in contact with floor joist on both sides, subfloor at the top, and sill plate/foundation wall at the bottom) without compression. Insulation should be placed in contact with the rim joist. The perimeter of the insulation must be sealed with spray foam. Windows Windows were once thought to be a major air leakage problem. However, the gaps and holes in a home’s air barrier are usually much more significant than air leakage around windows and doors. Consequently, window and door air sealing has been deemphasized as part of weatherization. The following air sealing measures are done when identified with the blower door. Air Sealing Window air sealing measures should be accomplished using lead-safe weatherization practices (see section titled “Lead Safe Weatherization Practices”). Caulking • Remove loose or brittle material before caulking. • If crack is deeper than 5/16 inch, install backer rod before sealing with caulk. Backing material includes flexible polyurethane, neoprene butyl rod, fiberglass or sponge rubber. • Use sealants with rated adhesion and joint movement characteristics appropriate for both the window frame and the building materials surrounding the window. Caulking should be applied in a manner that seals the area thoroughly and is neat in appearance. XIV.35 February 2013 Weatherstripping • Large gaps between sash and sill and sash and stops may be weatherstripped. Meeting rails may also be weatherstripped or planed. • Weatherstrip is to be secured by nails or staples, form a permanent airtight seal and not obstruct the operation of the sash. Exterior Storm Windows Metal exterior storm windows shall have the following qualities. • Frame should have sturdy corners and not tend to rack out-of-square during transport and installation. • The gasket sealing the glass should surround the glass edge and not merely wedge the glass in place against the metal frame. • Storm window sashes must fit tightly in their frames. • The window should be sized correctly and fit well in the opening. • Storm windows shall be caulked around the frame at time of installation except for weep holes that shall not be sealed. If weep holes are not manufactured into new storm window, weep holes shall be drilled into them. • Storm window sashes must be removable from indoors. • Wood storm window inserts shall fit neatly within window frame with the appropriate turn buttons, latches or closing hardware. • Fixed storm windows shall not restrict the exiting capacity and access required for emergency exits. Window Repair Window repairs are considered “incidental repairs”. Glass Replacement • Glass should be secured with glazing points (2 inches from each corner and not less than 8 inches apart) and puttied with latex or oil based glazing compound, or sealed with plastic or vinyl glazing strips. • Glass set in metal frames should have metal-glazing clips no more than 12 inches apart and within 4 inches of each corner and the joint between the two surfaces puttied. XIV.36 February 2013 • Glass over 25 inches in either dimension should not be less than “B” grade double strength. • Safety glass is required in windows located within 12 inches of a door when the bottom edge is less than 60 inches above the floor or if panes are larger than 9 ft2 when the bottom edge is less than 18 inches above the floor. Re-glazing • Window glazing compound should only be replaced if the existing glazing is deteriorated to the degree that the window glass is in jeopardy of falling out if the sash. • Caulk may not be used in place of a glazing compound. • A coat of primer or linseed oil must be applied to wood sashes before the glazing compound is applied. • Glazing compound is to be tooled smooth to form a concave surface and be neat in appearance. Stops Window stops should be installed in such a way as to ensure a tight seal between the jamb, sash and stop. Ensure that window operates smoothly following stop adjustment.

At least one NFRC label must be removed by the contractor and submitted with the contractor’s invoice upon completion of the home for verification. The remaining NFRC labels shall be left on the window for removal by the final inspector. Windows may only be replaced if SIR is greater than or equal to 1.0. XIV.38 February 2013 Doors Doors have a small surface area and their air leakage is more of a comfort problem than a serious energy problem most of the time. Doors may only be replaced if SIR is greater than or equal to 1.0. Air Sealing The following air sealing measures are done when identified with the blower door. Weatherstripping Door hardware should be tightened and door adjusted to close snugly against its stops before weatherstripping is applied.

Turn-on exhaust fan. After 10 seconds, read pressure reading on manometer. If pressure reading on manometer is greater than 8.0 Pa, select a larger opening on the flow meter. If E1 is already being used (the largest opening), the fan exhaust is outside the upper range of the flow meter (124 CFM). If the pressure reading on the manometer is less than 1.0 Pa, select a smaller opening on the flow meter. If E3 is already being used (the smallest opening), the fan exhaust is below the lower range of the flow meter (10 CFM). Use chart on side of flow meter to determine the flow for the measured pressure and the appropriate position (E1, E2, or E3). With the blower door at -50 Pa, place the pressure-pan completely over a grille or register to form a tight seal. Record rather than a breach in the duct system. Remove registers on ducts with elevated readings and inspect the boot connection. Seal boots and re-test with the pressure-pan (see section 31532, “Duct Sealing Materials”). Pressure-Pan Standards Following weatherization work; • No more than half of the pressure-pan readings shall be higher than 4.0 Pa and • No readings shall be greater than 8.0 Pa (Figures 100-8 and 100-9). Mechanical Standards Combustion Efficiency and Venting This combustion efficiency and venting section specifies maintenance, repair and efficiency improvements to the fire side of the heating appliance. Procedures outlined here require training, skill, experience and knowledge of the health and safety hazards associated with combustion heating systems. Natural Gas and Propane Gas-burner Inspection, Testing and Correction Perform the following inspection procedures and maintenance practices on all gas-fired furnaces, boilers, water heaters and vented space heaters. Refer to Table 300-1 for acceptable combustion test analysis values. 1. Inspect the burners for dust, debris, misalignment and other flame-interference problems. Look for soot, burned wires and other evidence of flame roll-out 2. Clean, vacuum and adjust burners XIV.43 February 2013 3. Clean and adjust thermostat and check anticipator setting. 4. Determine that pilot is burning (if equipped) and that main burner ignition is satisfactory. Test pilotsafety control for complete gas valve shutoff when pilot is extinguished. Install new thermocouple (if an intermittent ignition device, or IID, is not present or not being installed). Adjust pilot flame so that the hot tip of the thermocouple is enveloped by the flame. 5. Observe flame characteristics if soot, CO, or other combustion problems are evident. Remove causes of CO and soot, such as closed or blocked primary air intake, over-firing and flame impingement. 6. Check venting system for proper size, pitch and connection by referencing NFPA 54. 7. Check venting system for obstructions, blockages or signs of condensation. 8. Check high limit control for proper operation. 9. Measure gas input • Adjust gas input if burners are over- fired or under-fired. Adjust input by adjusting gas pressure to between 3.3” and 4.7” water column (w.c.) for natural gas and 10 “ w.c. to 11” w.c. for propane, or replace the burner orifices. 10. Conduct Combustion Safety Test (see section title, “Combustion Safety Testing”). There are four parts to this test. 1.Worst Case Depressurization (see section 3121); the worst case condition for a Combustion Appliance Zone (CAZ) is established; in other words, the greatest magnitude of negative pressure in the CAZ under which the combustion appliances might have to operate is determined. The following three tests are conducted under these conditions. 2. Spillage, the combustion appliance is fired and checked for spillage. Spillage must stop within three minutes after the appliance is fired (the spillage test only applies to natural draft appliances). 3. Draft, draft must be established within three minutes. Minimum draft pressures shown in Table 300-3 must be reached within ten minutes of appliance operation or when the flue gas temperature has leveled-off. 4. Carbon Monoxide; maximum carbon monoxide (CO) reading is 100 parts per million (ppm). Conduct steady state efficiency test (see section 313, “Steady State Efficiency Test”).

Assessors/Mechanical Weatherization Workers/Final Inspectors must perform a gas leakage test on all gas supply lines, couplings, joints and connections. Find gas leaks with an electronic combustible-gas detector, often called a gas sniffer. • Sniff all valves and joints with the gas sniffer. • Locate leaks using a non-corrosive bubbling liquid designed for finding gas leaks. All gas leaks must be repaired. Combustion Air A combustion appliance located in a confined space, surrounded by materials that are tight or marginal air barriers may need an outdoor source of combustion air. For every 1,000 Btu input, there should be 2 square inches (in2) of free ventilation area. For example, the furnace and water heater are located in a furnace closet. The furnace has an input rating of 100,000 Btus. The water heater has an input rating of 40,000 Btus. There should be 280 in2 of free ventilation area to the furnace room [(100,000 + 40,000)/1,000= 140 x 2 in2 = 280 in2]. Fuel Oil Systems These procedures pertain to oil-fired furnaces, boilers and water heaters. Oil-burner Inspection and Testing All oil burners shall be inspected and tested. Use visual inspection and combustion testing to evaluate oil burner operation. Refer to Table 300-1 for oil heating system guidelines. A smoke test should precede combustion testing. If the smoke number is greater than 2, efforts to reduce smoke should precede combustion testing to protect the combustion testing equipment from damage. The following steps are a minimum standard for oil-burner evaluation. XIV.47 February 2013 • • • • Inspect burner and appliance for signs of soot, overheating, fire hazards, or wiring problems. Inspect fuel line for leaks. Inspect heat exchanger and combustion chamber for cracks, corrosion, or dirt. Check to see if flame ignition is instantaneous or delayed. Flame ignition should be instantaneous. • Sample undiluted flue gases with a smoke tester, following the smoke-tester instructions. Compare the smoke smudge left by the gases on the filter paper with an approved scale to determine smoke number. • Test for CO with flue gas analyzer in undiluted flue gases upstream from the barometric draft control. A CO reading of 100 ppm is considered the maximum acceptable level. • Set up and operate house under worst-case depressurization identified in section titled, “Worst Case Depressurization”, when measuring appliance draft. Measure chimney draft downstream from the barometric draft control and over-fire draft. Minimum draft pressures shown in Table 300-3 must be reached within ten minutes of appliance operation for each natural draft combustion appliance. • Determine steady-state efficiency from O2 percentage and flue gas temperature in undiluted flue gases upstream from the barometric draft control. • Check and clean thermostat. • Technicians may need to perform other tests to diagnose efficiency, safety, or operational problems—oil-pump pressure or transformer voltage, for example. Oil burner Maintenance and Adjustment Perform some or all of the following maintenance tasks as needed to optimize safety and efficiency. • • • • • • • • • • • • • • • • Verify correct flame-sensor operation. Clean or replace burner nozzle. Clean the burner’s blower wheel. Clean or replace oil filter(s). Clean or replace air filter. Remove soot and sludge from combustion chamber. Remove soot from heat exchange surfaces. Clean the oil pump screen. Clean dust, dirt and grease from the entire burner assembly. Set oil pump to correct pressure. Adjust air shutter for minimum smoke. Adjust barometric damper to about 0.03-to-0.06 inches W.C. draft downstream from the barometric draft control (see Table 300-3). Adjust gap between electrodes to manufacturer’s specifications. Repair the ceramic combustion chamber, or replace it if necessary. Replace or adjust barometric damper. Measure CO in undiluted flue gases upstream from the barometric draft control. A CO reading of 100 ppm is considered the maximum acceptable level. XIV.48 February 2013 After these maintenance procedures, the technician shall perform the diagnostic tests described above to evaluate improvement made by the maintenance procedures and to determine if fine-tuning is required. Electric Heating Systems The following measures shall be done on all electric furnaces. • • • • • • • • • • • • • Check and clean thermostat. Check, clean and oil blower motor if applicable. Clean all filters. Replace if necessary. Vacuum and clean housing around electric elements, if applicable. Vacuum and clean all fins on electric- baseboard systems, if applicable. Wood Burner Safety Inspect stove, vent connector and chimney for correct clearances from combustible materials as listed in NFPA 211. Ensure that stove is sitting on a noncombustible floor. Inspect vent connector and chimney for leaks and seal leaks with a high- temperature sealant designed for use with metal or masonry. Inspect chimney and vent connector for creosote build-up and clean chimney if significant creosote build-up exists. Inspect the house for soot on seldom- cleaned horizontal surfaces. If soot is present, replace the gasket on the wood- stove door, seal other air leaks and take steps to improve draft, as necessary to reduce indoor smoke emissions. Inspect and clean damper and/or combustion air intake if present Check and replace fire door gaskets if applicable. Check catalytic converter for repair or replacement if applicable. Conduct Worst Case Depressurization test to check for potential back drafting. Combustion Safety Testing Assessors, mechanical contractors and final inspectors are required to do Combustion Safety Testing. Mechanical contractors are required to complete these tests following completion of work each day as well as at job completion. Architectural contractors and crews are required to do a Spillage Test-Out (see section titled, “Spillage Test-Out”) at the end of each work day. The purpose of combustion safety testing is to ensure that vented combustion appliances in a home are vented properly. Proper venting is essential to the operation, efficiency, safety and durability of combustion appliances. Air tightening the home can weaken draft and weatherization work can reduce the heater’s operating XIV.49 February 2013 time, resulting in a cooler flue. Tightening a home can also reduce air to combustion appliances resulting in backdrafting and/or “lean burns” that produce carbon monoxide. There are four parts to this test. 1. Worst Case Depressurization); the worst case condition for a Combustion Appliance Zone (CAZ) is established; in other words, the greatest magnitude of negative pressure in the CAZ under which the combustion appliances might have to operate is determined. The following three tests are conducted under these conditions. 2. Spillage; the combustion appliance is fired and checked for spillage. Spillage must stop within three minutes after the appliance is fired (the spillage test only applies to natural draft appliances). 3. Draft; draft must be established within three minutes. Minimum draft pressures shown in Table 300-3 must be reached within ten minutes of appliance operation or when the flue gas temperature has leveled-off. 4. Carbon Monoxide; maximum carbon monoxide (CO) reading is 100 parts per million (ppm). If a house contains more than one CAZ, combustion safety testing must be performed for each area. Additionally, if more than one vented combustion appliance is located in a CAZ, each must be tested for safe operation under worst case conditions. Combustion appliances include furnaces, boilers, water heaters, fireplaces and vented space heaters. Potential solutions for Combustion Safety Testing failures are presented in section 3125. Worst Case Depressurization “Worst case” is defined as the configuration of the house that results in the greatest negative pressure in the area of the vented combustion appliance or fireplace (CAZ). Worst Case Depressurization (WCD) must be done in all homes. The following are exceptions to this requirement: 1. If the house or mobile home is all-electric with no combustion appliances, woodstoves or fireplaces, or all combustion appliances are sealed combustion (direct vent). 2. If the home has a boiler and has no exhaust equipment, including clothes dryers, vented bath and kitchen fans, vented central vacuum systems, fireplaces, woodstoves, etc. 3. If the CAZ is located outside the thermal boundary and there are no return ducts in the CAZ. However, always perform this test if the CAZ is in a vented crawl space or a basement deemed to be outside the thermal boundary. XIV.50 February 2013 4. If apartments have no combustion appliances other than direct-vent combustion appliances. Manometer Set-Up Set up the digital manometer as follows to measure pressure difference of a combustion zone with reference to the outside. • Connect a hose from the “reference” tap on the digital manometer to the exterior of the home. • Connect a hose from the “input” tap on the digital manometer to within two feet of the combustion appliance. This hose is not needed if measurements are taken while standing in the CAZ. Measurements made while doing Worst Case Depressurization testing will likelybe quite small. Trying to take these readings on a windy day can be very difficult. Care should be taken to protect the tip of the exterior hose from the wind. One method for countering the effects of wind is by placing a plastic “T” fitting in the tip of the exterior hose. Run another hose to the windward side of the home and another hose to the leeward side of the home from the “T” connection. House Set-Up House should be set-up for winter conditions. • • • • • • • • All windows and exterior doors should be closed. Open all interior doors. This includes bathroom and kitchen doors and door to CAZ. Turn off all exhaust fans, including dryer. Remove lint filter from dyer. If dirty, remove filter from furnace. Otherwise, leave filter in place. Do not remove filter cap if present. Close supply air registers if present in the CAZ. Close damper on fireplace, if present. Set water heater to pilot and ensure that other combustion appliances are turned off. Measuring Worst Case Depressurization 1. Set the adjusted baseline pressure if using the DG-700 manometer with house set- up as described above. This is the pressure in the CAZ resulting from stack-effect air leakage. Generally, the colder the outdoor temperature, the greater the magnitude of this baseline value. Measure and record baseline pressure difference if using the older DG-3 manometer (P1). P1 will be 0 Pa if using the DG-700 manometer. 2. Turn on clothes dryer and all exhaust fans in house. Turn on central vacuum cleaner if present. Do not turn on whole house fans2. Record pressure difference (P2).3. Turn on the furnace air handler, leaving on all the exhaust fans. If cooling is present, run the air handler on high speed. Record pressure difference (P3). XIV.51 February 2013 4. Position all the doors. If the pressure in the room is greater than in the house (positive pressure), close door. If the pressure in the room is less than in the house (negative pressure), open the door. If you’re using a smoke pencil, smoke the door undercut. If smoke comes out of the room or does nothing, leave the door closed. If smoke is drawn into the room, open the door. Begin this test on the room furthest from the CAZ. Include bathroom doors and other rooms with exhaust devices behind them. Bathrooms, for example, will most likely have a supply air register, but no return. Existing bathroom exhaust fans generally have low exhaust rates such that the supply air is greater than the air being drawn by the exhaust fan putting the bathroom under positive pressure, thus the door would be closed. The last door to be tested should be the door to the CAZ. After all the doors have been positioned as described above, record the pressure difference (P4). Additional information about reading pressures between rooms and the main body of the house may be found in section titled, “Duct Induced Pressures”. Solutions to room imbalance problems may also be found in that section. 5. Use highest depressurization reading for each CAZ. The baseline pressure difference (P1) is subtracted from the largest pressure difference measured under each operating condition (P2, P3 or P4). Compare value to the Worst Case Depressurization values shown in Table 300-4. If depressurization is greater than the values shown in Table 300-4, the CAZ fails Worst Case Depressurization and pressure relief will be required (see section titled, “Solutions to Combustion Safety Testing Failures”). Worst Case Depressurization Limits Table 300-4 (Depressurization measurements shown are for the CAZ with reference to the outside) Appliance Gas fired furnace, boiler, water heater Oil fired furnace, boiler, water heater Fireplace (wood or gas) Airtight fireplace, wood stove Induced draft appliances Chimney Height (ft) 13 or less 14 – 20 + 21 13 or less 14 – 20 + 21 all heights Unlined Chimneys on Exterior Wall -5 Pa (0.02 in) -5 Pa (0.02 in) -5 Pa (0.02 in) -4 Pa (0.016 in) -4 Pa (0.016 in) -4 Pa (0.016 in) -3 Pa (0.012 in) Metal Lined, Insulated or Interior Chimneys -5 Pa (0.02 in) -6 Pa (0.024 in) -7 Pa (0.028 in) -4 Pa (0.016 in) -5 Pa (0.02 in) -6 Pa (0.024) -4 Pa (0.016 in) all heights all heights -10 Pa (0.04 in) -15 Pa (0.06 in) -10 Pa (0.04 in) -15 Pa (0.06 in) XIV.52 February 2013 Spillage Test (natural draft appliances only) Fire the appliance with the smallest Btu capacity first and test for spillage at the draft diverter with a smoke pencil. Spillage should cease within three minutes. If spillage ends within three minutes, fire all the other connected appliances simultaneously and test the draft diverter of each appliance for spillage. Proceed with the draft test if there is no spillage after three minutes. The appliance fails if there is spillage after three minutes. Turn off appliance and the exhaust fans and open all the interior doors. Allow the vent to cool and then re-test for spillage, draft and CO under natural conditions. Operating the blower door will help cool the combustion gases. Measure the net change in pressure from worst case to natural in the CAZ to confirm worst case depressurization. See section titled, “Solutions to Combustion Safety Testing Failures”, for potential actions for appliances that fail the spillage test. Draft Test Draft must be established within three minutes. Minimum draft pressures shown in Table300-3 must be reached within ten minutes of appliance operation or when the flue gas temperature has leveled-off. Draft test is only done for natural draft and induced appliances. Draft does not have to be measured for direct vent sealed combustion appliances. Natural Draft Appliances • • • • • Drill test hole 2 feet from draft hood or the first available straight run of pipe. See section titled, “Natural Draft Appliances”, for sealing test holes. Fan Induced Appliances Drill test hole about 1 foot away from where the gases exit the appliance. Hole should be in a straight piece of vent pipe away from turns (inducer fans and turns can cause turbulence and make stable readings difficult to obtain). • See section titled, “Fan Induced Appliances”, for sealing test holes. If measured draft is below the minimum draft pressures listed in Table 300-3, check for flue or chimney obstructions, disconnected vents or an improperly designed vent system. Check the National Fuel Gas Code (NFGA) for proper vent sizing. See section titled, “Heating Appliance Venting”, for additional information. Take action to improve draft, if inadequate because of improper venting, leaky venting, obstructed chimney or lack of combustion/dilution air. Seal leaks in vent connectors and chimneys with high temperature sealant. See section titled, “Solutions to Combustion Safety Testing Failures”, for other actions that may be taken for appliances that fail the draft test. XIV.53 February 2013 Carbon Monoxide (CO) Testing CO readings are often taken at the same location in the vent connector as combustion efficiency readings (see section titled, “Steady State Efficiency Test”). A CO reading of100 ppm is considered the maximum acceptable level. A reading in excess of 100 ppm indicates that the appliance needs to be adjusted or repaired. Natural Draft Appliances • Readings must be taken just before the emissions are diluted by room air at the draft diverter. Drilling a hole is often not necessary. Note that the CO reading is taken at a different location in the vent connector than the draft test. Where the appliance has multiple burners and cells, each cell of the heat- exchanger must be tested separately. Use the highest CO reading (not the average) when deciding the appropriate course of action. Fan Induced Appliances • Drill test hole about 1 foot away from where the gases exit the appliance. Hole should be in a straight piece of vent pipe away from turns (inducer fans and turns can cause turbulence and make stable readings difficult to obtain). See section titled, “Fan Induced Appliances”, for sealing test holes. Direct Vent Sealed Combustion Appliances (condensing) • • The recommended testing point for condensing appliances is to sample the gasses at the outside of the house by inserting the test probe into the PVC vent pipe at least 6 inches. If testing cannot be done on the exterior because the vent pipe is not accessible, testing can be done by drilling the PVC vent pipe near the furnace. Test hole must be drilled and tapped with threads for 1/8” pipe threads and then sealed with a plastic pipe plug and sealant. Proper technique and equipment must be used to seal this pipe as it is under positive pressure and improper sealing will allow vent gasses to enter the house. Test holes can be drilled in vertical pipes or the top half of horizontal pipes Solutions to Combustion Safety Testing Failures following are potential solutions for Worst Case Depressurization, spillage and draft failures. a. Check for blockage in the vent system and, if found, correct the problem. b. Check vent system for leaks, including missing or loose cleanout doors or open or cracked mortal joints. Seal vent system as appropriate. Lining a chimney may solve the problem. c. Properly seal return duct leakage in the CAZ. XIV.54 February 2013 d. Increase the CAZ air volume by connecting the CAZ to other areas within the conditioned volume of house. e. Increase the CAZ air volume by connecting the CAZ to the outdoors. f. Install a manufacturers’ outdoor air kit for the failed appliances. This is an option with a number of fired furnaces, boilers and water heaters. g. Install fan to supply air to pressurize the CAZ. It is best to link the controls of such a make-up air fan to the operation of the combustion appliance(s) in the CAZ. h. If opening doors solve a combustion safety test failure, consider door undercuts, transfer grilles, jumper ducts or in-door transfer grilles. i. For high CO emissions, the appliance should be cleaned and tuned and tested for CO emissions again. Contact Weatherization Agency if high CO emission problem cannot be corrected. Steady State Efficiency Testing Combustion analyzer used for testing must be within the manufacturer’s calibration period and have a calibration sticker with the calibration date affixed to it. The analyzer should be started-up (calibrated) in a source of known fresh air during the calibration period – usually outside the home. Natural Draft Appliances The following inspection procedures and maintenance practices are required for all natural draft appliances in addition to items 1 through 12 as noted in section titled, “Gas Burner Inspection, Testing and Correction”. • Test holes Single wall pipe is preferred location for test holes, but double wall B vent can be drilled if necessary. Seal inner pipe with RTV and metal tape over the outer pipe. Single wall pipe is to be sealed with metal tape. Butyl tape is not to be used. • Determine steady-state efficiency (SSE) using flue gas analyzer measuring in undiluted flue gases below the draft diverter. Where the appliance has multiple burners and cells, each cell of the heat-exchanger must be tested separately. • Measure O2 level and stack temperature in undiluted gases (before they enter the draft hood). O2 level should be between 4% and 9%. Net stack temperature should be between 300oF and 600oF. Fan Induced Appliances The following inspection procedures and maintenance practices are required for all fan induced appliances in addition to items 1 through 12 as noted in section titled, “Gas Burner Inspection, Testing and Correction”. • Test holes Test hole should be located about 1 foot away from where the gases exit the appliance. XIV.55 February 2013 Test hole should be in a straight piece of vent pipe away from turns (inducer fans and turns can cause turbulence and make stable draft readings difficult to obtain).

Adjust as necessary to meet Product Manufacturer’s Instructions for net stack temperature and O2 (generally, O2 is between 4% and 9%). Heating Appliance Venting Inspect chimney, vents and vent connectors to ensure adequate draft, clearance, soundness and freedom from combustible deposits. Clean if necessary. Repair or replace sections of the venting system that are seriously corroded or rusted, contain cracks or holes, and/or are unsealed, loose, or disconnected. Ensure all venting materials meet clearances from combustible materials in accordance with the applicable NFPA code. When called for, correct cases where vent clearance requirements are not met. Ensure that vent/chimney connections are securely fastened. Horizontal runs in the vent connector should have a rise of at least ¼ inch per foot. Existing connectors that do not meet this requirement are to be repaired unless the appliance passes the Combustion Safety Tests (see section titled, “Combustion Safety Testing”). Venting Devices, Materials and Sizing The National Fire Protection Association (NFPA) is the authoritative source for information on materialchoice and sizing for vent connectors and chimneys. The information in this venting section is based on the following NFPA documents. Consult these references for specific venting requirements and tables for vent and chimney sizing. • NFPA 54: The National Fuel Gas Code XIV.57 February 2013 • • NFPA 31: Standard for the Installation of Oil-Burning Equipment NFPA 211: Standard for Chimneys, Fireplaces, Vents, and Solid-Fuel-Burning Appliances 1996 Edition Vent Connectors A vent connector connects the venting outlet of the appliance with the chimney. Approved vent connectors for gas- and oil-fired units are made from the following materials. • • • • • • Galvanized-steel pipe (> 0.018 in. thick), Type-B vent, consisting of a galvanized-steel outer pipe and aluminum inner pipe (> 0.027 in. thick), Stainless-steel pipe (> 0.012 in. thick), Type-L vent, like Type-B only with a stainless-steel inner pipe, or Various manufactured vent connectors. A wye connector is the preferred connection when a common flue is used for more than one appliance. Vent connections are not to be located directly across from each other when an induced appliance is used. Masonry-Chimney Liners Masonry chimneys and clay tiled chimneys should have a liner if they are not properly sized. If an 80% furnace or boiler has been installed, the masonry chimney will need a liner as it is probably oversized. The liner should have a small air space between itself and the masonry structure of the chimney to insulate the liner from rapid heat loss. A liner used to vent solid fuel may not also be used to vent liquid or gaseous fuel. Unlined masonry chimneys should be lined with galvanized-steel vent pipe, Type-B vent, or a flexible liner. Unlined chimneys or chimneys with deteriorated liners should be relined. For interior chimneys, flexible metal liners may be used. For external chimneys, galvanized-steel vent pipe, Type-B vent or a flexible metal liner, insulated with vermiculite or equivalent, may be used. Sizing Vent Connectors and Chimneys Sizing tables and procedures for chimneys and vent connectors are found in NFPA documents numbered 54, 31 and 211 as described earlier. NFPA 54, the National Fuel Gas Code, Part 11 provides tables for sizing various types of chimneys and vent connectors. Forced Air System Standards The overall system efficiency of an oil or gas forced air heating system is affected by blower operation, duct leakage, balance between supply and return air, and duct insulation levels. XIV.58 February 2013 Furnace Repair When possible, furnaces should be repaired to a safe and efficient operating condition. Cracked heat exchangers should be replaced per manufacturer’s instructions. Contact the Grantee if total repair costs, including heat exchanger replacement, exceed 50% of furnace replacement cost. Furnace Operation Standards and Improvements Apply the following furnace-operation standards to maximize the heating system’s seasonal efficiency and safety. Refer to Table 300-5 for furnace operating guidelines. • • • • • • • • • • • • • • • • • Check temperature rise between the supply air plenum and return air plenum after 10 minutes of operation. Refer to manufacturer’s nameplate for acceptable heat rise (supply temperature minus return temperature). The heat rise should be between 40°F and 70°F with the lower end of this scale being preferable for maximum efficiency. The fan-off temperature should be between 85°F and 100°F, with the lower end of the scale being preferable for maximum efficiency. The fan-on temperature should be 115°F if possible. The high-limit controller should shut the burner off before the furnace temperature reaches 200°F. Operate unit with blower disconnected to check high limit control and repair as necessary. If needed, seal (with compatible sealing materials) unsealed blower compartment openings and blower compartment door. If the heating system does not conform to these standards consider the following improvements. Reduce heat rise by cleaning or changing dirty filters, cleaning the blower, increasing fan speed and improving ducted air circulation. Adjust fan control to conform to the above standards or replace the fan control if adjustment fails. Adjust the high-limit control to conform to the above standards or replace the high-limit control. In all cases, the following furnace measures will be done: Furnace filters shall be cleaned or replaced. Two extra filters of proper size and type shall be left with the client. Filter changing procedure shall be explained to client. The blower belt shall be adjusted or changed if necessary. Belt should be free of cracks and have one inch of free play when measured between pulleys. Pull the blower fan and clean. Vacuum the compartment. Inspect the blower assembly’s electrical wiring system for bad insulation and loose connections and repair as necessary. Inspect the blower and squirrel cage for excessive free play and correct as necessary. The blower motor shall be lubricated if appropriate. The thermostat shall be checked, cleaned and leveled.

Consider fan control replacement. 130o 150o Ducts Duct Leakage Sites The following joints should be inspected and sealed. Ducts located outside the thermal boundary or in an intermediate zone like a ventilated attic or crawl space should be sealed. • • • • • • • Seal holes in the air handler and joints between the air handler and the supply and return ducts. Filter slot must have system that will cover the opening but is easy for the occupant to open and close. Seal leaky joints between main supply and return ducts and their branches. Seal leaky joints between building materials composing cavity return ducts, like panned floor cavities and furnace return platforms. Even better: replace cavity return ducts with new metal return ducts. Seal leaky joints between supply and return registers and the floor, wall and ceiling to which they are attached. Secure metal duct joints with screws, seal them with mastic, and support joints with duct hangers. XIV.60 February 2013 • Flex duct runs should be mechanically attached to the plenum/trunk/boot with clamps or cable ties and sealed. Flex duct should be run as straight as possible with a minimum of long radius turns and should be supported with appropriate hangers to prevent sagging. • Permanently seal open supply and return registers in unconditioned areas. • Patch or replace metal ducts that have rusted through and ducts with holes cut in them. • Seal penetrations made by wires or pipes traveling through ducts. Even better: move the pipes and wires and patch the holes. • Seal return air grilles in basement. Re-check temperature rise to assure that it is within the operating limits of the furnace. Duct Sealing Materials Duct sealing mastics and tapes should be UL181A or UL181B labeled. • Duct mastic: the preferred material because of its superior durability and adhesion. Apply at least 1/16- inch thick and use reinforcing mesh for all joints wider than 1/16 inch or joints that may experience some movement. Tape: An approved aluminum duct tape may be used when duct mastic is not used. Duct surfaces around the joint need to be clean in order for the tape to adhere properly. Tape should never be expected to hold a joint together nor expected to resist the force of compacted insulation or joint movement. Joints should rely on mechanical fasteners to prevent joint movement or separation. Butyl-aluminum tape: High quality tape designed for duct sealing is effective and durable when applied to clean surfaces. Cloth duct tape is not an acceptable duct sealant material because of its history of adhesive failure. Duct Insulation Insulate supply and return ducts that run through unconditioned areas outside the thermal boundary such as vented crawl spaces and attics. Use minimum R-8 insulation on supply ducts. • • • • Always perform necessary duct sealing before insulating ducts. Use fiberglass insulation 3 to 6 inches thick (minimum R-8) with foil-skrim-kraft facing or vinylfacing. Vapor barrier must be placed to the outside with no exposed insulation. Insulation should cover all exposed ducts, especially in air conditioned homes. Even a small void in the insulation can dampen a large section of insulation through condensation. Insulation should be fastened by mechanical means such as stuck- ups, twine, or plastic straps. Tape can be effective for covering joints in the insulation to prevent air convection, but tape will usually fail if expected to resist the forces of compressed insulation or the insulation’s weight. XIV.61 February 2013 Duct System Airflow The airflow capacity of the air handler may be checked in relationship to the size of the furnace or air conditioner. For combustion furnaces there should be 110 to 150 cfm of airflow for each 10,000 Btuh of output. Central air conditioners should deliver 400 cfm of airflow per ton of cooling capacity. Heat pumps should deliver 450 cfm of airflow per ton of heating capacity. Central Air Conditioners Cooling Clean & Tune • Measure air flow across the evaporator coil. Airflow across the indoor coil should be 400 CFM per ton for a wet coil (condensation on coil) and 425 CFM per ton for a dry coil (no condensation on coil), plus or minus 50 CFM. • Check for correct amount of refrigerant. Follow the manufacturer’s specification for refrigerant charge. The airflow across the indoor coil should be adjusted and verified before the refrigerant charge is checked. Any refrigerant that must be evacuated must be captured rather than illegally releasing it to the atmosphere. • Test for refrigerant leaks using a leak detector. • Clean the outdoor condenser coil. • Check for and seal duct leakage in central systems. Duct sealing and insulation is especially important for ductwork running through unconditioned spaces. Chances are high that the weatherization workers already completed this inspection and work. • Verify the correct electric control sequence and make sure that the heating system and cooling system cannot operate simultaneously. • Inspect electric terminals, clean and tighten connections and apply a non- conductive coating if necessary. • Oil motors and check belts for tightness and wear. • Check the accuracy of the thermostat. Dirty air conditioning coils located in main ducts or air handlers are a common cause of low airflow and resultant low heating and cooling efficiency. • • • • • Identify the coil location and the coil surface where the air enters - most of the dirt will be attached to this surface. Remove access panel in air handler or duct; or cut access panel in duct; or disassemble duct to gain access to air-conditioning coil. Using a stiff brush, remove surface dust, dirt and lint. Spray the coil with cleanser and after a while spray water to rinse out the cleanser and dirt. Repeat the spraying if necessary. Observe whether the pan and drain hose are doing their job. Water and cleanser should be flowing out the end of the hose, not overflowing into the duct. Clean the pan and unplug the hose if necessary. XIV.62 February 2013 Central Air Conditioner Replacement Replacement central air conditioners must be ENERGY STAR rated with a minimal SEER3 of 14.0. Air conditioners shall be selected to have a rated sensible heat ratio (SHR) of 0.75 or less. Indoor coils and line sets shall also be changed if a different refrigerant type will be used in the system. All new air conditioners shall carry a minimum one year warranty on parts and labor and a five year warranty on the compressor. Each client shall receive all manufacturer’s product warranty information, clear maintenance instructions, educational information and a local telephone number for warranty problems. Contractor shall size the system properly utilizing the Residential Load Calculation, Manual J by the Air Conditioning Contractors of America or other approved method. Sizing calculations must be provided to the Weatherization Agency for inclusion as a permanent part of the client file. The following characteristics of the house and occupants shall be considered: • • • The size of the home and the number and orientation of the windows.
