Building Narrative 01
This section is dedicated to the ever evolving history of the building in general, including
remodels, additions, building uses, etc… It is here to introduce a stranger and a friend to
the building under care.
Building Narrative 01
The Animal Sciences Lab, located on the
south side of Gregory Drive just east of
the South Quad, is a four story, 149,211
square foot brick building that was built
in March of 1950 with addendums
reaching into the spring of 1952. The
building is almost entirely dedicated to
laboratory research; however, there is a
lecture hall on the first floor for
classroom instruction.
Although faculty at the University was
assigned to agriculture from the
inception, the College of Agriculture,
consisting of a School of Agriculture and
a School of Horticulture, was first recognized in 1873. The Department of Animal Husbandry
was recognized as a separate subject matter field in 1901 and the Department of Dairy
Husbandry formed in 1902. Over the next four decades many sciences grew into their own
departments, while the remaining component of the department was briefly named Dairy
Production, but new titles for the Departments of Animal Science and Dairy Science were
adopted in 1947. In 1985, the two departments were merged to form the Department of
Animal Sciences. Today, the department includes 40 faculty positions, seven visiting and
support staff, 107 graduate students and approximately 500 undergraduates.
The following is a current timeline of the building and its systems:
o 1950:
o 1952:
o 1989-1992:
o 1996:
o 1997-1998:
o 2002:

Building Narrative 01
PLUMBING SYSTEMS
No investigation has been made of the plumbing systems as of the time of this narrative.
HVAC SYSTEMS
Original air handling systems that were installed in 1952 have since been replaced in the
1988-92 remodel/addition. The building is conditioned by seven custom built-up air handling
units and four general exhaust fans, all with variable frequency drives. Six of the units are
located on the roof while the other is in the penthouse mechanical room. The building HVAC
system is a variable air volume system that is dependent upon the local level pressure
controllers at each lab. Such antiquated but operational pressure controllers react to the
room-to-corridor pressure relationship, seeking to maintain the lab negative at all times.
Fume hoods have velocity controls allowing for an independent damper on the exhaust duct
to modulate to control velocity across the face of the hood. When the sashes are closed, the
damper backs off and the supply damper also reduces volume unless overridden by the
thermostat. Four hood exhaust fans are in parallel located on the roof. They are controlled
per a static pressure sensor located in the penthouse canyon space on top of barrel exhaust
duct. To maintain the discharge velocity, bypass dampers at each end of the barrel duct
modulate to maintain flow. Due to over sizing of the system and excessive modulation of
bypass dampers, RCx found it advantageous to turn off all fans except one to maintain the
negative air flow. In addition to the four general exhaust fans, there are also seven hood
exhaust fans on the roof. There is a “mechanical canyon” in the center of the building for
mechanical, electrical, and plumbing risers.
The building is supplied with 134,000 CFM of conditioned air. The air handling unit
construction is custom built from 4” thick insulated panels. Units 1 - 4 have a return fan,
filter bank, steam heating coils, chilled water cooling coils, and supply fan. Unit 5 does not
have a heating coil. Five condensate meters exist (per H312, 1989 DD), and they were
specified to be the “Cadillac” style. The heating coils are designed for an entering
temperature of 20 deg F. This allows for 65% outside air to enter each of the four systems.
This total sums to 41,600 CFM. This amount falls short of the 57,130 CFM of total building
exhaust at maximum. However, this does allow for a diversity of 73% of total exhaust
operational at any one time.
The existing controls in the labs and offices are pneumatic type (Sheet V310, 1989 DD).
One common static pressure signal controls the four supply fan inlet vanes. One common
return static pressure sensor controls the four return fans inlet vanes. Each fan had inlet
vanes, however, now there are VFD’s observed for each fan.
A project in 1998 replaced the pneumatic controls in their majority with DDC controls using
Alpha components at the air handling units. Sequences of the equipment can be located in
the Tab 08 Control Diagrams & Sequences.
ELECTRICAL SYSTEMS
No investigation has been made of the electrical systems as of the time of this narrative.

OTHER SYSTEMS
This building has an associated chilled water plant located in the basement. This plant was
isolated from the campus loop but was later converted to connect to the campus chilled
water loop. The quantity of chilled water used is metered separately in the basement. Its
utility use and costs are not seen by the Animal Sciences Laboratory, but rather are cared
for by the Utilities Division of Campus.
SITE PLOT PLAN

OCCUPANCY REQUIREMENTS & SCHEDULING
There are hours of operation for the facility and the HVAC controls have been programmed
to run according to those schedules. Any changes desired should be referred to Facilities
and Services DDC Programmers.

EMERGENCY RESPONSE
This facility is not an emergency command center and is not currently used as a staging
area. In case of an emergency refer to: http://www.dps.uiuc.edu/erg.pdf to locate
telephone numbers and methods to safely encounter many emergency situations. In the
event of a electrical interruption, the latest file is attached at the end of this section.
INDOOR ENVIRONMENTAL QUALITY REQUIREMENTS
This facility requires adequate ventilation in all of its zones, especially the laboratories. Care
must be taken to maintain safe air change rates and outside air levels.
UTILITY COST / ENERGY SAVING GOALS
The primary energy saving goals for this site are to limit energy use where possible, taking
full advantage of the control systems by optimizing system performance and scheduling.
Minimizing the percentage of outside air during unoccupied times will drastically reduce the
energy consumption. The building energy demand needs to be reduced while maintaining
occupant comfort and lab safety levels.
DOCUMENTATION AND TRAINING NEEDS
The building operations director, assistants, building mechanics, and any route mechanics
who will adjust, troubleshoot, or work on the air handling units or their associated parts,
MUST be trained in accessing the DDC control system information. They MUST be able to
understand setpoints, schedules, and diagnosing minor system upsets using trend reports.
This system manual must be provided to staff for the successful daily operations and
maintenance of the facility to preserve the facility in its best condition.
PERFORMANCE ACCEPTANCE CRITERIA
The primary criterion used to define acceptable performance for this facility is the
requirement to limit occupant complaints while maintaining reasonable utility bills. The
systems should rarely be forced out of service. Occupied space should be kept inside the
70F – 75F zone year round and “hot” and “cold” calls minimize. To provide this
performance, the HVAC control system must function properly and be viewable through
graphical information. The operators must be able to adjust setpoint temperatures, humidity
levels and building pressure.

Personal Safety Tips – Active Shooter/Threat
The following safety tips from the Division of Public Safety are offered as a response guide for use during incidents of
active shooter threats.
1. The first step in personal safety is to maintain an awareness of the situation and environment around you;
be prepared to take appropriate action if a threat presents itself.
2. Evacuate the area (whether inside or outside a building) if you know that it is safe to do so – seek shelter
in a nearby building if the threat is exterior to a campus building;
3. If a threat presents itself, seek cover and barricade yourself (with others if possible) by placing as much material
between you and the threat – remain quiet and turn off lights to make the area appear unoccupied;
4. As soon as it is safe to do so, notify authorities by calling 911 (or 9-911 from a campus phone) and provide
as much information as possible;
5. Do not approach emergency responders – let them come to you;
6. Remain under cover until the threat is passed or you have been advised by law enforcement that it is safe to exit;
7. Activate cell phones to receive campus emergency notification that may be sent through the “UI-Emergency” System.1

elevator is identified.
Power Outage
Tornado Watch means tornadoes are possible in your area. Remain alert for approaching storms, and be prepared
to seek shelter.
Tornado Warning means a tornado is imminent or has been indicated by Doppler radar or reported by storm
spotters. Move to your pre-designated place of safety immediately!
Severe Thunderstorm Watch means severe thunderstorms are possible in your area.
Severe Thunderstorm Warning means a severe thunderstorm is imminent or has been indicated by Doppler radar
or reported by storm spotters.
Tornado sirens are sounded for those areas in the path of the tornado throughout Champaign, Urbana, and Savoy.
These sirens are intended to be heard outside of buildings and are not designed to be heard inside every building.
It is recommended that each building and/or department purchase a NOAA Weather Radio with a battery backup
and tone-alert feature that automatically alerts you when a Watch or Warning is issued Purchase a battery-powered
commercial radio and extra batteries as well.
What to do during a tornado warning:
When the tornado sirens sound or a tornado has been sighted, go to a safe shelter immediately.
1. Move to a pre-designated shelter, such as a basement.
Assist those with special needs in getting to the shelter
area.
2. Put as many walls as possible between you and the
outside. Get under a sturdy table and use arms to
protect head and neck. Stay away from windows and
open spaces. Stay there until the danger has passed.
3. If there is no basement, go to an interior room on the
lowest level (closets, interior hallways, or restrooms).
Do not open windows.
4. In a high-rise building, go to a small, interior room or
hallway with no windows on the lowest floor possible.
5. Get out of vehicles, trailers, and mobile homes
immediately and go to the lowest floor of a
sturdy nearby building or a storm shelter.
6. If caught outside with no shelter, lie flat in a
nearby ditch or depression and cover your
head with your hands. Be aware of potential for
flooding.
7. Never try to outrun a tornado in a car or truck;
instead, leave the vehicle immediately for safe
shelter. Tornadoes are erratic and move swiftly.
8. Watch out for flying debris. Flying debris from
tornadoes causes most fatalities and injuries.
Do not call 911 unless you need to report an emergency, such as a fire, medical emergency or severe building
damage. 911 lines need to be kept open and available for emergency calls.

• If a fire or explosion is involved
• Your name, phone number, and location
n Follow instructions provided by the emergency responders.
n Arrange for someone to meet the emergency responders.
n Evacuate, if necessary. Remain in a safe designated area until released by emergency responders.
n Present the Material Safety Data Sheet of involved substances to emergency responders if this information
is available.
Do not attempt to clean up a spill or release unless you are trained to do so and have the proper
equipment.
n
If you are notified of a hazardous materials incident, follow the instructions provided by the emergency
service officials:
n
n
n
Clear the area immediately if instructed to do so by the emergency providers, providing assistance to those
with special needs.
When evacuating, move crosswind, never directly with or against the wind.
Take roll call of your unit, and report headcounts to your unit head.
If you observe what you believe to be an unauthorized release of any pollutants to the environment, call
the Division of Public Safety immediately at 333-1216.
Hazardous Materials - Pollutants Incident
Call 9-911 from any campus phone or 911 from a cell phone or off-campus phone.
DO NOT MOVE the victim unless there is an immediate threat to life or you need to move
the victim to provide care.
In an emergency use universal precautions (i.e. gloves and rescue masks).
Cardiopulmonary resuscitation (CPR)
1. Assess the situation:
ƒ
Is the person conscious or unconscious?
ƒ
If the person appears unconscious, tap or shake his shoulder and ask loudly, “Are
you OK?”
ƒ
If the person doesn’t respond, call 9-911 from a campus phone or 911 from a cell
phone or off-campus phone.
2. Locate an Automatic External Defibrillator (AED) if one is immediately available.
ƒ
Use the AED as you have been trained to do and as outlined on the device.
3. Perform CPR if trained to do so.
To Control Bleeding
1. Have the injured person lie down. If possible, position the person’s head slightly lower
than the trunk or elevate the legs if you do not suspect a head, neck, or back injury. If
possible, elevate the site of bleeding above the heart.
2. Apply pressure directly to the wound. Use a sterile bandage, clean cloth, or even a
piece of clothing. If nothing else is available, use your hand.
3. Continue with pressure until paramedics arrive.
4. Don’t remove the gauze or bandage. If the bleeding continues and seeps through the
gauze or other material you are holding on the wound, don’t remove it. Instead, add
absorbent material to stop it.
Medical emergency information continues on the next page.
Medical Emergencies
Chemical Burns
If the chemical burns the skin, follow these steps:
1. Remove the cause of the burn by flushing the chemicals off the skin’s surface with
cool, running water for 20 minutes or more. If the burning chemical is a powder-like
substance such as lime, brush it off the skin without exposing yourself before flushing.
2. Remove clothing or jewelry that has been contaminated by the chemical.
3. Wrap the burned area loosely with a dry, sterile dressing or a clean cloth.
4. Rinse the burn again for several more minutes if the victim complains of increased
burning after the initial washing.
Minor chemical burns usually heal without further treatment.
Seek emergency medical assistance if:
ƒ
The victim has signs of shock, such as fainting, pale complexion, or breathing in a
notably shallow manner.
ƒ
The chemical burned through the first layer of skin and the resulting second-degree burn
covers an area more than 2 to 3 inches in diameter.
ƒ
The chemical burn occurred on the eye, hands, feet, face, groin, or buttocks or over a
major joint.
If you are unsure whether a substance is toxic, call the poison control center at (800) 222-1222.
If you seek emergency assistance, bring the chemical container or a complete description of the
substance with you for identification.
Medical emergency information continues on the next page.
Medical Emergencies
Burns
To distinguish a minor burn from a serious burn, the first step is to determine the degree and the
extent of damage to body tissues. These three classifications will help you determine
emergency care:
First-Degree
The least serious burns are those in which only the outer layer of skin (epidermis) is
burned. The skin is usually red, with swelling and pain sometimes present. The outer
layer of skin hasn’t been burned through. Treat a first-degree burn as a minor burn
unless it involves substantial portions of the hands, feet, face, groin, or buttocks or a
major joint.
Second-Degree
When the first layer of skin has been burned through and the second layer of skin
(dermis) also is burned, the injury is termed second-degree burn. Blisters develop and
the skin takes on an intensely reddened, splotchy appearance. Second-degree burns
produce severe pain and swelling.
If the second-degree burn is no larger than 2 to 3 inches in diameter, treat it as a minor
burn. If the burned area is larger or if the burn is on the hands, feet, face, groin, or
buttocks or over a major joint, get medical help immediately.
For Minor Burns, including second-degree burns limited to an area no larger than 2 to 3 inches
in diameter, take the following action:
Cool the burn. Hold the burned area under cold running water for 15 minutes. If this is
impractical, immerse the burn in cold water or cool it with cold compresses. Cooling the
burn reduces swelling by conducting heat away from the skin. Don’t put ice on the burn.
Consider a lotion. Once a burn is completely cooled, apply an aloe vera lotion, a triple
antibiotic ointment, or a moisturizer to prevent drying and increase comfort.
Medical emergency information continues on the next page.
Medical Emergencies
Cover the burn with a sterile gauze bandage. Don’t use fluffy cotton, which may
irritate the skin. Wrap the gauze loosely to avoid putting pressure on the burned skin.
Bandaging keeps air off the area, reduces pain, and protects blistered skin.
Caution:
Don’t use ice. Putting ice directly on a burn can cause frostbite, further damaging your
skin.
Don’t break blisters. Fluid-filled blisters protect against infection. If blisters break,
wash the area with mild soap and water, then apply an antibiotic ointment and a gauze
bandage. Clean and change dressings daily. Antibiotic ointments don’t make the burn
heal faster, but they can discourage infection. Certain ingredients in some ointments
can cause a mild rash in some people. If a rash appears, stop using the ointment. If it’s
a major burn, don’t apply any ointment at all (see below).
Third-Degree
The most serious burns may be painless and involve all layers of the skin. Fat, muscle
and even bone may be affected. Areas may be charred black or appear dry and white.
Difficulty inhaling and exhaling, carbon monoxide poisoning, or other toxic effects may
occur if smoke inhalation accompanies the burn.
For Major Burns, dial 9-911 from a campus phone or 911 from a cell phone or non campus
phone or call emergency medical assistance. Until an emergency unit arrives, follow these
steps:
1. Don’t remove burnt clothing. However, do make sure the victim is no longer in contact
with smoldering materials or exposed to smoke or heat.
2. Make sure the burn victim is breathing. If breathing has stopped or you suspect the
person’s airway is blocked, try to clear the airway and, if necessary, do cardiopulmonary
resuscitation (CPR) if trained to do so.
3. Cover the area of the burn. Use a cool, moist sterile bandage or clean cloth.

EARTHQUAKES
The following are some helpful tips that should be practiced daily to help prepare for an earthquake:
• Identify what equipment you should shut down if time permits.
• Look around your area and decide where the safe spots are, under sturdy tables, desks or against inside walls.
• Determine where the danger areas are: near windows, hanging objects, tall unsecured furniture (bookcases,
cabinets, appliances), chemical sites. Most casualties in earthquakes result from falling materials.
• Store flammable and hazardous chemicals in proper cabinets.
• Keep breakables and heavy objects on lower shelves whenever possible.
• Make sure latches on cabinets, process tanks, storage tanks, and closets are secured.
Safety Tips
• Stay indoors if already there. If you’re in a high-rise building, do not use elevators.
• If you’re outdoors, stay in the open, away from buildings, trees, and power lines. Don’t go near anything
where there is a danger of falling debris.
Emergency Procedures
After an earthquake, follow these guidelines:
• Check for injuries and follow first-aid procedures.
• Be prepared for aftershocks. Earthquakes sometimes occur in a series of tremors, which could last for
a period of several days. Aftershocks, or even a series of aftershocks, are common after earthquakes
and may last for a few seconds to perhaps as long as 5 minutes or more.
• Don’t re-enter damaged buildings. Aftershocks could knock them down.
• In the event of a fire or personal injury, go to the nearest safe telephone to call for help.
• Be alert for gas and water leaks, broken electrical wiring, downed electrical lines, or ruptured sewer lines.
Whenever possible, turn the utility off at the source.
If you do enter a building, use atmospheric testing equipment to check for leaking chemical or gas lines.
If problems are detected, leave the building immediately and notify your supervisor, an emergency responder
(fire or police), or incident command. If phones are working you may also call 9-911 from a campus phone
or 911 from a working cell phone or off campus land line phone.
• Know your shutdown procedures.
Earthquakes
Immediately activate the building’s fire alarm system.
Evacuate the building unless otherwise notified.
Call 9-911 from any campus phone. Call 911 from a cell phone or from off campus.
If you discover a fire:
1. 2. 3. 4. Manually activate the building’s fire alarm system.
Immediately evacuate the building, closing doors and windows behind you.
DO NOT USE THE ELEVATORS.
Locate those persons with special needs, and provide assistance if possible.
Otherwise, provide their location to emergency responders.
5. Report to your department’s designated gathering point to be accounted for.
6. Call 9-911 from any campus phone or 911 from a cell phone or from off campus.
Once the fire alarm is activated:
1. Walk quickly to the nearest exit. Do not use the elevators.
2. If you are able, help those who need special assistance.
3. Notify fire personnel if you believe someone may still be in the building.
4. Gather away from the building and emergency responders at a pre-designated location.
DO NOT re-enter the building until the fire department has cleared the scene.
If caught in smoke:
1. Do not breathe the smoke!
2. Drop to your knees and crawl to the closest safe exit.
3. Breathe through your nose, and use a shirt or towel to breathe through, if possible.
If trapped in a building:
1. Close all doors and windows.
2. Wet and place cloth material around and under the door to prevent smoke from entering.
3. Attempt to signal people outside of the building. Call for help using a telephone or cell phone.
USING A FIRE EXTINGUISHER:
1. Report the fire first (Call 9-911 from any campus phone, or call 911 from a cell phone or off campus).
2. Use a fire extinguisher only if you have been trained to do so. Improper use of an extinguisher can increase
the hazard.
3. If you have any doubt of your ability to fight the fire, exit immediately.
4. If you decide to use a fire extinguisher, place yourself between the fire and your exit from the area.
5. To use the fire extinguisher, follow the PASS method.
P ull the pin. This will break the tamper seal if one is provided.
A im low, pointing the extinguisher nozzle (or the horn or hose) at the base of the fire.
S queeze the handle to release the extinguishing agent.
S weep from side to side at the base of the fire until the fire is out. Watch the area.
If the fire re-ignites, repeat the steps above.

This is a panel unit which is constructed on the roof. The coils and filters are relatively clean. The
coils are starting to pick up debris in the fins. The dampers are opposed blade dampers. The mixed
air dampers will not close 100% but they will open 100%. The exhaust air dampers have broken
linkage, which means that one of the blades will not operate. The linkage is internal and the
dampers will have to be taken out to be worked on. The dampers are 24” wide x 42” tall. There are
two damper sections one on top of the other and they are tied together with an external linkage
bar.

The air flow readings on this unit revealed that the supply fan was at 14,408 CFM at 42 HZ. And the
return fan was at 10,111 CFM at 38 HZ. The mixed air dampers were at 67% open and the exhaust
at 33%.
This is a mixed air supply fan with a steam preheat coil, a cooling coil and an associated return fan.
The supply and return fans have variable frequency drives and are controlled through the DDC
program to maintain a specific duct static setting. The mixed air dampers, preheat control valve and
chilled water control valve are also controlled through the DDC program with pneumatic actuation.
The outside air duct divides into four separate ducts within the mixed air plenum of the supply fan.
The four ducts have their own damper and damper motor with two of the dampers having electric
end switches mounted on them to keep the supply fan from starting until these dampers are fully
open. These four outside air dampers open when the supply fan starts, they are not under control of
the mixed air transducer. The outside air dampers get their control air signal from the same electric
- pneumatic switch that is associated with the supply smoke damper. The south outside air damper
does not fully open. The mixed air dampers, preheat control valve and chilled water control valve all
have pilot positioners. The two-way chilled water valve and preheat control valve do not leak
through to the coil when closed. There are dampers with pneumatic actuators in the supply and
return ducts that are designated as smoke dampers. These actuators have damper end switches
mounted on them to prevent the supply and return fans from starting until the dampers are fully
open. These smoke or isolation dampers get their control air signal from an electric – pneumatic
switch that is tied electrically into the variable frequency drives. This EP switch is located in the fan
control panel. When the drives start up the electric switch is made and the pneumatic signal is sent
out to the pneumatic actuators. The mixed air dampers were very stiff due to dried out weather
stripping and not operating in unison when RCx visited. The dampers were lubed. But once the lube
dries out the problem will reoccur.
This AHU has a supply fan and a return fan that is totally controlled by the BAS which is the Barber
Coleman Network 8000 type, via LCM 1 and GCS 1 that is networked from GCM 20. LCM 1 has no
spare points and GCS 6 has 3 spare points for future enhancements. The supply and return fans run
via VFDs of the ABB 500 type. The VFDs have 6 points wired to them, VFD stop/start, VFD
command, VFD status, VFD fault, VFD amps, and VFD hertz. The return fan VFD is controlling the
building pressure from 2 static sensors that are named EBLDGSTC and WBLDGSTC that are
programmed into a HILO block labeled HILO: STTC-1/4 and the HILO block will take the lowest
valve of both static pressures and the LOOP block for the return fan VFD will control off of that
pressure. The building pressure set point is 0.05 in. wc. The BAS is monitoring discharge air temp,
mixed air temp, preheat temp and the 35 degree freeze stat alarm. There are 3 AO points on LCM 1
that are commanding the mixed air dampers, preheat valve and the chilled water valve. The BAS is
controlling the discharge air temp with the discharge air temp sensor in the summer mode and
controlling the mixed air temp with the mixed air temp sensor in the winter mode. There are 2
smoke dampers on this AHU. One on the supply fan duct and one on the return fan duct. The
dampers are controlled by EP switches in the LCP that are energized from the respective VFD. When
the supply fan and return fan VFD’s get the command to run, they will energize they’re respective
smoke damper EP switch in the LCP. When the damper is fully open a damper end switch will close.
The EP’s also command two minimum outdoor air dampers as well. The outdoor air dampers have
end switches that are wired in series with the smoke damper end switches. The switches are wired
back to the VFD enable circuit and it will allow the motors to start. There are 3 safety contacts wired
back to the supply fan VFD. They are a smoke alarm relay, 35 degree freeze stat alarm, and a
motor disconnect interlock switch. These external faults will drop out the external fault relay in the
supply fan VFD and stop the VFD and shut its smoke damper via the EP switch in the LCP. Then the
return fan VFD will shut down via a set of run relay contacts from the supply fan VFD in series with
Page 3 of 19
Monday, July 06, 2009
Owner’s Operating Requirements 03
the return fan smoke damper end switch that will drop out the return fan VFD external fault relay. If
the smoke damper actuator should fail, the fans will shut down as well. The supply fan VFD will
maintain 1 in of static pressure between two static pressure sensors that are named STTC-S and
STTC-N. This is done in software via a HILO block that will take the lowest pressure from both
sensors and use it to maintain the 1.90 in WC. The mixed air temp sensor, discharge air temp
sensor, preheat temp sensor, and the supply air static pressure sensor were calibrated. The 35
degree freeze stat functions properly. The mixed air damper, preheat valve and the chilled water
valve transducers are of the Johnson control type and were calibrated during RCx visit. This unit
does not have 40 degree freeze stats. However it does have return air temp sensors and humidity
sensors. The static senor is installed in the LCP pertaining to its AHU control. The pneumatic pick up
tube is assumed to be 2/3 the way down the supply air duct from the supply fan. After the AHU had
everything fixed during the RCx visit, the summer/winter logic back was put back into operation and
the chilled water valve closed and the mixed air dampers were controlling its set point. The mixed
air temp was put to a set point of 60 and the chilled water set point and preheat temp set point
were left at 55 degrees. It was also noticed that when this fan is shut down for any reason and
started back up, the preheat valve opens 100% and then ramps closed. The discharge air temp
goes high for about 8 minutes and then gets under control via the mixed air dampers. Maybe this is
a winter time safety feature.
NOTE: After further review of the events that have taken place with chilled water coils on campus,
it was checked to see if any chilled water coil safety’s were present on this AHU. It is known that
there aren’t any 40 degree freeze stats on this unit as mentioned in the general notes, so the BAS
software was checked for some sort of software safety and it was found that this AHU has a
software safety that will take the chilled water valve 100% open if the 35 degree freeze stat trips. It
will also take the preheat valve 100% open as well.

This unit is a panel unit which is constructed on the roof. The coils and filters are relatively clean.
The coils are picking up debris and could be vacuumed. The dampers are opposed blade dampers
with weather stripping. All of them need adjustment and lubrication annually. The isolation damper
on the supply fan is broken; the bottom two blades are not attached to the linkage anymore and
will not operate at all, thus allowing air to enter when the unit is down.

After taking flow readings on the unit it was determined that the supply fan was at 16,783 CFM at
39 HZ, and the return was at 11,721 CFM at 35 HZ. These readings were taken with the mixed air
dampers at 100% and the exhaust dampers closed.
This is a mixed air supply fan with a steam preheat coil, a cooling coil and an associated return fan.
The supply and return fans have variable frequency drives and are controlled through the DDC

smoke dampers. These actuators have damper end switches mounted on them to prevent the
supply and return fans from starting until the dampers are fully open. These smoke or isolation
dampers get their control air signal from an electric – pneumatic switch that is tied electrically into
the variable frequency drives. This EP switch is located in the fan control panel. When the drives
start up the electric switch is made and the pneumatic signal is sent out to the pneumatic actuators.
The mixed air dampers were very stiff due to dried out weather stripping and not operating in
unison. The dampers were lubed during the RCx visit and they are operating better. But once the
lube dries out the problem will reoccur. The rubber diaphragm for the return damper motor and the
pilot positioner were replaced during the RCx visit.
This AHU has a supply fan and a return fan that is totally controlled by the BAS which is the Barber
Coleman Network 8000 type, via LCM 1 and GCS 3 that is networked from GCM 20. LCM 1 has no
spare points and GCS 3 has 3 spare points for future enhancements. The supply and return fans run
via VFDs of the ABB 500 type. The VFDs have 6 points wired to them, VFD stop/start, VFD
command, VFD status, VFD fault, VFD amps, and VFD hertz. The return fan VFD is controlling
building pressure from 2 static sensors that are named WBLDGSTC and WBLDGSTC that are
programmed into a HILO block labeled HILO: STTC-1/4 and the HILO block will take the lowest
valve of both static pressures and the LOOP block for the return fan VFD will control off of that
pressure. The building pressure set point is 0.05 in. WC. The BAS is monitoring discharge air temp,
mixed air temp, preheat temp and the 35 degree freeze stat alarm. There are 3 AO points on LCM 1
that are commanding the mixed air dampers, preheat valve and the chilled water valve. The BAS is
controlling the discharge air temp with the discharge air temp sensor in the summer mode and
controlling the mixed air temp with the mixed air temp sensor in the winter mode. There are 2
smoke dampers on this AHU. One on the supply fan duct and one on the return fan duct. The
dampers are controlled by EP switches in the LCP that are energized from the respective VFD. When
the supply fan and return fan VFDs get the command to run, they will energize they’re respective
smoke damper EP switch in the LCP. When the damper is fully open a damper end switch will close.
The EPs also command two minimum outdoor air dampers as well. The outdoor air dampers have
end switches that are wired in series with the smoke damper end switches. The switches are wired
back to the VFD enable circuit and it will allow the motors to start. There are 3 safety contacts wired
back to the supply fan VFD. They are a smoke alarm relay, 35 degree freeze stat alarm, and a
motor disconnect interlock switch. These external faults will drop out the external fault relay in the

supply fan VFD and stop the VFD and shut its smoke damper via the EP switch in the LCP. Then the
return fan VFD will shut down via a set of run relay contacts from the supply fan VFD in series with
the return fan smoke damper end switch that will drop out the return fan VFD external fault relay. If
the smoke damper actuator should fail, the fans will shut down as well. The supply fan VFD will
maintain 1 in of static pressure between two static pressure sensors that are named STTC-S and
STTC-N. This is done in software via a HILO block that will take the lowest pressure from both
sensors and use it to maintain the 1.90 in. WC. The mixed air temp sensor, discharge air temp
sensor, preheat temp sensor, and the supply air static pressure sensor were calibrated during the
RCx visit. The 35 degree freeze stat functions properly. The mixed air damper, preheat valve and
the chilled water valve transducers are of the Johnson control type and were calibrated during RCx
visit. This unit does not have 40 degree freeze stats. However it does have return air temp sensors
and humidity sensors. The static sensor is installed in the LCP pertaining to its AHU control. The
pneumatic pick up tube is assumed to be 2/3 the way down the supply air duct from the supply fan.
After the AHU had everything fixed during the RCx visit, the summer/winter logic back was put back
into operation and the chilled water valve closed and the mixed air dampers were controlling its set
point. The mixed air temp was put to a set point of 60 and the chilled water set point and preheat
temp set point were left at 55 degrees.
NOTE: After further review of the events that have taken place with chilled water coils on campus,
it was checked to see if any chilled water coil safety’s were present on this AHU. It is known that
there aren’t any 40 degree freeze stats on this unit as mentioned in the general notes, so the BAS
software was checked for some sort of software safety and it was found that this AHU has a
software safety that will take the chilled water valve 100% open if the 35 degree freeze stat trips. It
will also take the preheat valve 100% open as well.

This unit is a panel unit which is constructed on the roof. The coils and filters are relatively clean.
The coils are starting to pick up debris and could be vacuumed. The dampers are opposed blade
with weather stripping. All of the dampers were in need of adjustment and lubrication. The isolation
damper for the supply fan does not seal, it allows back flow when the unit is down. The blades are

The flow reading revealed that the supply fan was at 17,666 CFM at 41 HZ and the return fan was
at 12,474 CFM at 37 HZ. These readings were taken with the mixed air dampers at 100% and the
exhaust dampers closed.
This is a mixed air supply fan with a steam preheat coil, a cooling coil and an associated return fan.
The supply and return fans have variable frequency drives and are controlled through the DDC
program to maintain a specific duct static setting. The mixed air dampers, preheat control valve,
and chilled water control valve are also controlled through the DDC program with pneumatic
actuation. We replaced the existing Honeywell transducers with Johnson Controls transducers to
allow the fine tuned calibration of the transducers to the operating span of the controlled devices.
The outside air duct divides into four separate ducts within the mixed air plenum of the supply fan.
The four ducts have their own damper and damper motor with two of the dampers having electric
end switches mounted on them to keep the supply fan from starting until these dampers are fully
open. These four outside air dampers open when the supply fan starts, they are not under control of
the mixed air transducer. The outside air dampers get their control air signal from the same electric
- pneumatic switch that is associated with the supply smoke damper. The pilot positioners for the
mixed air dampers, preheat control valve and chilled water control valve were recalibrated during
the RCx visit. The two way chilled water valve and preheat control valve do not leak through to the

This AHU has a supply fan and a return fan that is totally controlled by the BAS which is the Barber
Coleman Network 8000 type, via LCM 3 and GCS 7 that is networked from GCM 20. LCM 3 has 2

via VFDs of the ABB 500 type. The VFDs have 6 points wired to them, VFD stop/start, VFD
command, VFD status, VFD fault, VFD amps, and VFD hertz. The VFDs are controlling from 2 static
sensors that are named SF6-STTC and SF7-STTC. The BAS is monitoring discharge air temp, mixed
air temp, low suction static safety and the 35 degree freeze stat alarm. There are 2 AO points on
LCM 3 that are commanding the mixed air dampers and the chilled water valve. The BAS is
controlling the discharge air temp with the discharge air temp sensor in the summer mode and
controlling the mixed air temp with the mixed air temp sensor in the winter mode. There are 2
smoke dampers on this AHU. One on the supply fan duct and one on the return fan duct. The
dampers are controlled by EP switches in the LCP that are energized from the respective VFD. When
the supply fan and return fan VFDs get the command to run, they will energize they’re respective
smoke damper EP switch in the LCP. When the damper is fully open a damper end switch will close.
This switch is wired back to the VFD enable circuit and it will allow the motor to start. There are 3
safety contacts wired back to the supply fan VFD. They are a smoke alarm relay, 35 degree freeze
stat alarm, and a motor disconnect interlock switch. These external faults will drop out the external
fault relay in the supply fan VFD and stop the VFD and shut its smoke damper via the EP switch in
the LCP. Then the return fan VFD will shut down via a set of run relay contacts from the supply fan
VFD in series with the return fan smoke damper end switch that will drop out the return fan VFD
external fault relay. If the smoke damper actuator should fail, the fans will shut down as well. The
supply fan VFD will maintain 1 in of static pressure between both static pressure sensors. This is
done in software via a HILO block that will take the lowest pressure from both sensors and use it to
maintain the 1 in of static pressure. The mixed air temp sensor, discharge air temp sensor and both
supply air static pressure sensors were all calibrated during the RCx Visit. The mixed air damper and
the chilled water valve transducers are of the Johnson control type. This unit does not have 40

stat trips there is a select block that will take the chilled water valve to 100% open via priority #3 in
the analog output to the chilled water valve

FUME HOOD EXHAUST
There are four common fume hood exhaust fans located out on the roof off of the penthouse.
There are only two exhaust fans that run at any given time. If a fan that is in the lead stops
operating then the backup fan will start up and run. There is an isolation damper for each
exhaust fan that is open when the exhaust fan is operating and closed when it is off. There are
two dilution dampers on each end of the exhaust duct that modulates to maintain a specific
static pressure within the exhaust system. These dilution dampers have pneumatic actuators
with pilot positioners that are controlled by the direct digital control system. The original
Honeywell transducers were replaced with new J.C. transducers and calibrated.
LAB PRESSURE DIFFERENTIAL CONTROLS
The lab differential pressure controls consist of a Johnson Controls R-3180 low range
differential pressure controller with the low volume branch signal going to the return
damper actuator and also piped to one side of a high pressure selector. The other side
of this selector is piped to the branch of the room thermostat which is also controlling
the control valve for the hot water reheat coil or coils. The branch line off of this high
pressure selector goes out to the supply damper actuator. The pressure differential
controller is trying to maintain a negative .02 pressure differential between the lab and
the corridor. All have inline air filters on the main air line piped to the controller and they
all have shown water and oil contamination in the pneumatic control system. Bruce
Mikos indicated that at one time Animal Science experienced an air dryer failure and the
control air system was flooded with water.
BUILDING PRESSURIZATION CONTROLS
Building pressurization is accomplished by controlling the static pressure on the supply
side of the fan systems for supply fans 1-4 and lagging the speed of the return fans that
are associated with these supply fans behind them. This is done through the DDC
controls and VFD drives. Originally the pressurization of the building was done by
measuring the atmospheric pressure on the west and east end of the building. There are
atmospheric pressure pick up sensors mounted on the outside west and east walls. The
west one is located outside the window of room 220 and the east one is outside the
window in room 270. The west pick up was damaged and it was repaired to put the
original building pressurization control scheme back in operation but it did not work well
and was reverted back to control sequence described above. The east static sensor is
also damaged and needs to be replaced to be used in the future, The west one should
be updated also if the building pressurization control scheme is going to reference
atmospheric pressure. The interior building pressure pick up is located just south of the
west entrance door to the canyon area in the middle north-south hallway on the second
floor. There is a ¼ inch copper line stubbed out into that hallway about 8 feet above the
floor.
TEMPERATURE CONTROL COMPRESSORS
Animal Science is currently getting their building compressed air for temperature control
and lab air from the compressed air system at Madigan Lab. Originally there was a
Page 17 of 19
Monday, July 06, 2009
Owner’s Operating Requirements 03
Quincy 15 horsepower duplex reciprocating compressor mounted over a receiving tank
for temperature control air. There is one compressor pump that has been removed from
this duplex setup making the compressor a single pump operation. This compressor has
been set up as a backup unit if for some reason the system loses compressed air from
Madigan Lab. The air dryer for the temperature control air is a Hankison desiccant air
dryer that has also been setup as a standby unit. The power for this air dryer is turned
on when the backup air compressor starts up and runs. The lab air compressor is a
Quincy 10 horsepower duplex reciprocating unit mounted over a receiving tank. This
unit is also a standby unit that starts and runs when the system loses air from Madigan
Lab. The lab air is piped through a Hankison refrigerated air dryer. This dryer has an
automatic float drain that is suppose to eliminate water that accumulates from the
refrigerated process that dries the compressed air. This float drain is a high
maintenance item that needs to be maintained and checked on frequent basis or it will
fail and flood the air system with water. The temperature control air is not dried again
once it enters the Animal Science building like the lab air is. Both air systems run
through separate air filter systems. The two filters on the lab air system are Deltec
filters with one in service and the other as a standby. The filters for the temperature
control air system are two Deltec inline filters. One is a micron filter and the other is a
coalescing oil removal filter with an electric automatic discharge drain attached to the
bottom of the filter housing to remove water from the filter body.
Heat Exchangers HX-1 and HX-2
HX-1 is for the perimeter hot water system and is totally controlled by the BAS. The BAS is doing
the stop/start commands to two hot water pumps P-12 and P-12A which run across line voltage
from MCC -3 – EM. The pumps being fed from this MCC being that it will still have power from an
emergency power generator will allow the building to stay warm in the winter time if you lose
power. Only one pump should run at a time and the lead pump will start if the outdoor air
temperature drops below 55 degrees. If the lead pump should fail the lag pump will start
automatically while sending out a pager alarm that the lead pump has failed. The BAS is
monitoring hot water supply temperature and hot water return temperature and controlling the
steam valve going to the exchanger.
HX-2 is for the reheat hot water system and is totally controlled by the BAS. The BAS is doing
the stop/start commands to two hot water pumps P-13 and P-13A which run across line voltage
from MCC - 5. Only one pump should run at a time and the lead pump will run 24/7 unless a
MTR block in the program will rotate to the lag pump or if the lead pump should fail the lag
pump will start automatically while sending out a pager alarm that the lead pump has failed. The
BAS is monitoring hot water supply temperature and hot water return temperature and
controlling the steam valve going to the exchanger. The set point for this exchanger is 160
degrees with no reset schedule. The transducer for the steam valve was replaced and calibrated.
The supply and return temperature sensors were also calibrated. Pump P-13 is locked out of
service by the machine shop.
The heat exchangers for the hot water perimeter radiation system and the hot water reheat
system are located on the mezzanine level of the chilled water plant which is attached to the
northwest side of the Animal Science Bldg. There is one heat exchanger for each system and
they both have DDC controls with pneumatic actuation. There is one large steam control valve
for each heat exchanger. The existing Honeywell transducers were replaced with new J.C.

transducers. The original industrial pilot positioner on the steam valve for the reheat heat
exchanger was replaced with a Barber Coleman pilot positioner. The transducers, actuator
positioners, and temperature sensors were calibrated during the RCx Visit. The steam control
valves do not leak through when they are closed to the exchanger.
Chilled Water Entrance
This entrance is located in the chiller plant in the basement. The return or isolation valve was
checked for proper operation and everything seemed fine. The open and close indications were
reading correctly. There was no close indication when the valve was closed. The dog on the close
limit switch was adjusted and it seems to be working fine at this time. The open indication is
working as well. The flow meter seems to be working fine. Some air bleeding out of the flow
control valve pilot positioner was present when it is commanded to be open. It appears to be a
normally open valve. This entrance is controlled by the BAS via LCM 3 that is also located in the
chiller plant.

Retrocommissioning Final Report 04
Executive Summary
The Retrocommissioning Team in conjunction with Facilities and Services Engineering
Division completed a retrocommissioning study of BUILDINGNAME, for the University of
Illinois. BUILDINGNAME was considered to be No. 25 in the Top 50 List of Energy
Consumers on campus, with an estimated $AMOUNT annual utility cost. The study was
funded by student fees in harmony with their vision to create a sustainable campus.
Retrocommissioning, or returning a building to its originally intended design while
integrating energy saving measures, is a snapshot in the life of a building that applies a
systematic investigation process to improve and optimize a building’s operation and to offer
suggestions to improve the overall maintenance. It is an independent process that focuses
on the building’s energy using equipment such as the HVAC and other mechanical
equipment, lighting equipment, and related controls. It may or may not emphasize bringing
the building back to its original intended design specifications. In fact, via the process, the
Retrocommissioning team may find that the original specifications no longer apply. The
process may result in recommendations for capital improvements, but its primary focus is to
optimize the building systems via performing long-needed maintenance and care for aged
systems, improving control strategies and allowing graphic displays, tailoring the building’s
energy needs by its current tenants, and by improving the very nature of operations and
maintenance. Details of this structured method are provided later in the report.
The retrocommissioning process began in January of 2008. It involved a coordinated effort
between the RCx Team, Directors of Engineering and Maintenance, Electricians Shop, Sheet
Metal Shop, Temperature Controls Shop, many Shop Foremen and the willing building staff
at Animal Sciences Laboratory (ASL). The process included reviewing documents,
conducting interviews with staff and inhabitants of the spaces, performing field
investigations, monitoring and analyzing building systems, developing a master findings list,
and assisting ASL with selecting measures for implementation. Some of these findings were
a mix of “operation and maintenance” repairs that had estimated paybacks of two years or
less and “energy saving projects” that were more costly to implement and therefore longer
paybacks. Additional measures are also sprinkled in were improvements that had potential
energy saving and equipment maintenance impacts, but the saving estimates were based
more on experience rather than energy modeling or engineering estimates.
Overall, the Retrocommissioning Team has reduced the energy consumption 22% at Animal
Sciences Laboratory. This will result in an estimated annual savings of $150,000. Such
implementation is ongoing and these preliminary results are rewarding. This report shows
the results of these persistent efforts.

Purpose
The University of Illinois has educated thousands of students over a period of a century.
Many of the existing buildings on campus were designed and constructed during an era of
abundance, when energy was abundant and economical. Buildings were designed around a
certain space intent, which over the years has dramatically changed with new departments
and space shifting. Operations and maintenance funding has not grown in proportion with
the expansion of the real estate of the university. Maintenance folks have been stretched
thin, assigned to care for 15, 20 or more buildings. Therefore, existing heating, ventilating
and air conditioning equipment and associated equipment have been and are being
neglected.
These factors have compounded to reduce the efficiencies and operation strategies of the
hundreds of pieces of equipment throughout campus, requiring increased expenditures on
energy utility costs and decreased tenant comfort. The future is showing an ever increasing
utility market, and therefore the essential need for improving the way energy is used. For
this very reason, the Retrocommissioning Project was funded to assist the University to
reduce the maintenance items, lower energy consumption, educate building tenants, and
give direction in using energy in a sustainable way.
Methodology
What is retrocommissioning? At the University of Illinois it a concentrated focus on the
building’s HVAC systems, since they consume the majority of the energy in a building. It is
a process whereby a team of engineers and technical individuals approach an existing
building with the goal of saving energy and improving tenant comfort, while restoring the
building systems to optimal performance. The process requires a review of the operations
and maintenance currently conducted in the facility. During field investigations the team
meets weekly and brainstorms on methods to improve the building’s performance and
efficiency. The basic process requires five fundamental procedures:

together to logically show the process at each point in time. The last part will discuss the
verification of savings that resulted from the decisions made by the Retrocommissioning
Team.

Retrocommissioning Final Report 04
Investigation and Data Collection
The retrocommissioning process began by collecting and evaluating data pertaining to
facility equipment and current operation. The primary tasks for this project are outlined
below.
Documentation Review
The first step of the investigative process consisted of obtaining as much building
documentation as possible to allow the Team to become familiar with the building and its
systems. Blueprints, shop drawings, and energy data were gathered and reviewed by the
RCx Team.
Site Assessment
The next step was to conduct the site assessment. First on the agenda was interviewing the
directors and assistants of the operations and maintenance staff at ASL. Questions were
asked to ascertain the facility’s operating condition, where specific, known challenges were,
what maintenance has been performed, and so on. The retrocommissioning process was
also explained and the rewards for assisting were discussed.
Many weeks were spent in the building investigating each HVAC piece of equipment and its
role in using energy. Each of its components was reviewed including: ductwork, coils,
control sequences, the state of the control valves and pneumatic hardware. Occupancy
schedules were noted, space temperatures were trended, and tenants were interviewed.
Discussions took place with the route mechanics to gain a more in-depth understanding of
the building HVAC equipment conditions over the last couple of years.
Analysis of Data
At each step along the way the findings were noted, then discussed at the weekly progress
meetings. Decisions were made at many of these meetings and the actions were followed
through on with the varying parties, which was sometimes immediate and at other times
sluggish. Therefore, the list below is generated in the form of tables showing the 1) finding,
2) Proposed RCx Solution, 3) The implicated cost estimate and payback expected, 4) If the
implementation took place or not, 5) Which party is/was responsible for actions.
The implementation of solutions was dependent upon the costs and responsibility factors
associated with such deficiencies. In many cases the RCx Team went ahead and resolved
the findings listed above with direction from Facilities and Services Engineering Director.
These immediate adjustments helped facilitate the energy savings that are observed
currently. Some solutions are quick paybacks, others of longer duration, and yet others that
are based on qualified engineering principles and experience.

Chilled water valve was modulated open (month of December) maintaining a
discharge temperature of 55 deg F (not using economizer cycle) at every air
handling unit 1-7. The preheat temp setpoint, mixed air setpoint, and discharge air
setpoint were all at 55 deg F. A logic block in the program called for two inputs to
control the chilled water valve. One was supply fan status and the other was just
ON. It would appear that the dampers quit working smoothly or the transducers
were not operating properly for control of the mixed air temperature.
Fixed dampers and inserted the “SUM/WIN” logic block back into operation to

Retrocommissioning Final Report 04
The Path to Success – Maintenance of Savings
A brand new vehicle that leaves the factory is perfect in every way; it’s been tested, proven,
crashed, and trashed. When the proud new owner drives away, there is an air of confidence
that the pieces will work in harmony and deliver the satisfaction they expect. However, this
satisfaction will only continue as long as the Owner is responsible and learns to maintain its
parts. Proud automobile ownership comes from a commitment to keep the auto in shape
and tuned per the manufacturer’s instructions.
Retrocommissioning has a very similar path. A brand new building, although having its
quirks, still possess’ new equipment, new parts, and new warranties. However, the following
year the equipment in the building needs care and preventative maintenance. Sometimes
years or decades go by before a building is approached with the idea of restoring, or even
improving upon, its efficiency. Retrocommissioning puts the building back on the path to
success, giving the Owner pride to own that real estate. After the Team leaves, the building
is once again under the jurisdiction of the Facility Operators. It is you the reader who must
continue on the legacy of maintaining the building system in its best condition possible,
operating at its peak efficiency, or better.
To maintain the building at its peak efficiency, it will require help from “mechanics”,
specifically trained route mechanics who know the building and its method of operation. It
will require following up on preventative maintenance tasks or creating new ones to take
care of repetitive causes contributing to system inefficiencies. This may require additional
funds, but much less than the inefficiencies will. Control systems will need to be calibrated
and checked. Utility data should be trended, kept monthly for seasonal comparisons, to
review and alert the operator to any deviations. The operator will then need to understand
what to do to maintain the energy savings and if not, to be able to speak with someone who
can assist. The Engineering Division of Facilities and Services would be available if the need
were to arise.
The Facility Operator and assistants are in the position to improve upon, or optimize the
work performed by the Retrocommissioning Team. There are many other opportunities for
savings. That event was a turning point. The operators should consider implementing steps
outlined in the publication LEED for Existing Buildings which is available online at
www.usgbc.org. Since there are many other buildings on campus to attend to, it may well
be the only visit during this decade. Therefore, operator, assistants, and route mechanics:
take your stewardship seriously! Treat the building and its systems as a brand new
automobile. Commitment will lead the building and its caretakers on the Path to Success.

OPERATIONS & MAINTENANCE PLAN 05
This section is dedicated to the men and women operating and maintaining the facility, as
well as the folks at F&S who assist in the building’s systems functioning smoothly and
efficiently. This section shall contain all items required to operate and maintain the building,
less the occupancy schedules which are in the Owner’s realm of activity.
Operating & Maintenance Plan 05
Purpose of Operation and Maintenance
Building O&M is the ongoing process of sustaining the performance of building systems
according to design intent, the owner’s or occupants’ changing needs, and optimum
efficiency levels. The O&M process helps sustain a building’s overall profitability by
addressing tenant comfort, equipment reliability, and efficient operation. Efficient operation,
in the context of O&M, refers to activities such as scheduling equipment and optimizing
energy and comfort-control strategies so that equipment operates only to the degree
needed to fulfill its intended function. Maintenance activities involve physically inspecting
and caring for equipment. These O&M tasks, when performed systematically,
increase reliability, reduce equipment degradation, and sustain energy efficiency.
These are vital for energy savings to continue over the life of the building.
It is the intent of this document to be dynamic, used to perform the building
operation and preventative maintenance (PM) for functionality and sustainability.
If there is a suggestion, please revise this form and submit the improvement to
the Operations and Maintenance Staff at Facilities and Services. That information
could be included on future editions of this document and in other facilities on
campus.
The Animal Sciences Laboratory is a building dedicated to the furthering of research in the
field of animal sciences. This facility requires optimum thermal comfort and indoor air,
visual and sound quality over the varying facility activities. With these ultimate objectives in
mind, the necessity is laid upon the operations and maintenance staff to follow through in
all required responsibilities throughout the facility. This may well require additional parttime or full-time assistance from a third party or by in-house means and an investment in
the required tools or computers.
The primary energy savings goals for this site are to limit energy use where possible, taking
full advantage of economizer function by maximizing the use of outdoor air for cooling and
to limit air conditioning and lighting functions during unoccupied hours, except where
needed. An O&M service plan for each piece of equipment should eventually be included in
this evolving document stating the tasks to be performed, the frequency, and the expected
time to perform them.
Prerequisites
The air handling units at this facility are progressively employing DDC controls in lieu of
pneumatic controls. Therefore, it is imperative that the call made to F&S requests the
proper mechanics, otherwise without understanding the systems can regress to operating
inefficiently. When the route mechanic or other is called, he/she must possess these two
prerequisites to work on the DDC systems:
•
•
MUST have access to a laptop or personal computer which is connected to
theDDC System in the building.
MUST have experience in working with DDC software and have password access
to the logic.

Operating & Maintenance Plan 05
Operations Tasks
Operations of this building are dependent upon sequences of operation found in the tab
“Control Diagrams and Sequences of Operation”. These sequences were developed or
reviewed and improved by the Retrocommissioning Team during their visit to the building in
November, 2008. Any questions as to the operations can be directed to the DDC Controls
Group or Retrocommissioning for assistance.
Unique to DDC systems is the ability to trend data. This operation allows the computer to
take “snap shots” of the system or sensor at specified time intervals (down to each minute).
This data can then later be observed in excel format or by graphical display. This trending is
very valuable to review system performance and to reveal non-optimal conditions.
Reviewing this data will assist the building operators in providing a more responsive zone
and increased energy savings. Trending can always be added to a system upon request to
the DDC Controls Group at Facilities and Services.

CONTROL DIAGRAMS & SEQ. 08
Temperature Controls
The temperature controls for many of the units can now be viewed from this web
page: TAC I/A Graphics
Hot Water Reheats – Great Hall
There are 11 hot water reheat coils for the Great Hall that are located in the trench area
below the Hall and just east of the costume shop. There are 11 zones that are being
controlled by a pneumatic master-sub master control system. The master controls consist of
a mixture of room thermostats and return duct transmitters. The sub master controls are
Honeywell dual input controllers that are looking at space temperatures and also the
discharge temperature from the reheat coils. The reset schedule is at 68 degree space
temperature the discharge temperature will be 85 degrees, at 72 degree space temperature
the discharge temperature will be 55 degrees. The dual input controllers are hunting and do
not appear to be calibrated correctly. The reheat valves are 3 way valves that range in size
from 3” to 2”. There are 2 new valves out of the 11 and only one of the zone valves is
leaking thru to the reheat coil when the valve is in bypass mode. That valve is for zone 1
and that supplies the projection booth. Randy Greever felt that several zone reheat valves
were leaking thru causing temperature problems in the Great Hall but I feel it is because of
the hunting in the zone reheat controllers.
Supply fan AHU-2 Great Hall
The Great Hall fan is a mixed air fan that has a preheat coil with a face and bypass damper
and a cooling coil; there is also a minimum outside and exhaust damper. The bypass for the
preheat coil also bypasses the cooling coil. The fan controls are DDC with pneumatic
actuation. One of the damper motors for the face damper on the preheat coil is a
problem the way it has been installed. It is in the minimum outside air intake
chamber and should be moved to the north mixed air chamber. To do this the drive
shaft for the face damper needs to be extended into the north mixed air chamber so the
damper motor can be relocated there.
Supply fan AHU-3 Lobby
The Lobby fan is a mixed air fan that has a preheat coil with a face and bypass damper and
a cooling coil; there is also a minimum outside and exhaust damper. The bypass for the
preheat coil also bypasses the cooling coil. The fan controls are DDC with pneumatic
actuation. The relief damper is to large for the damper motor, there needs to be
another motor installed for this damper. The steam reheat coil is divided into two
sections and the north section has been turned off because of a leak in the coil. The reheat
is controlled by a pneumatic controller installed above the stage area in the front lobby.

CONTROL DIAGRAMS & SEQ. 08
Supply fan AHU-4 Dual Duct
The dual duct fan is a mixed air fan with a preheat coil, face and bypass damper and a
cooling coil. The fan controls are DDC with pneumatic actuation. The cooling coil is for the
cold deck and maintains a 60 degree discharge temperature. The hot deck maintains a 100
degree discharge temperature. The mixing boxes for this fan all work and some are still
being controlled by old Honeywell pneumatic thermostats. These should be replaced with
new thermostats which would total up to be about 14 new thermostats.
Supply fan AHU-5 Festival Theatre
The Festival fan is a mixed air fan with a preheat coil, face and bypass damper and a cooling
coil; there is also a minimum outside air and relief damper. The bypass for the preheat coil
also bypasses the cooling coil. The fan controls are DDC with pneumatic actuation. There
are three steam reheat coils for the theatre that are controlled by space thermostats and
they are working correctly.
Supply fan AHU-1 Playhouse Theatre
The Playhouse fan is a mixed air fan with a preheat coil, face and bypass damper and a
cooling coil; there is also a minimum outside and relief damper. The bypass for the preheat
coil also bypasses the cooling coil. The fan controls are DDC with pneumatic actuation.
There are two steam reheat coils for the theatre that are controlled by space thermostats
and they are working correctly.

EXHAUST FAN EF-2A IS THE LAG FAN. IT WILL RUN IF THE BYPASS
DAMPER COMMAND DROPS BELOW 20% OUTSIDE AIR AND WILL
CONTINUE UNTIL THE DAMPER OPENS TO ABOVE 60% OUTSIDE
AIR. IT WILL THEN SHUT DOWN. IF EF-2A FAILS OR IF BLOCK
DPT.ROT_EF2 IS COMMANDED ON, EXHAUST FAN EF-2B WILL
BECOME THE LAG FAN AND WILL RUN WHEN REQUIRED BY THE
DAMPER POSITION THERMOSTAT.

Pneumatic Control Manual 717.1
Pressure Section
Product Bulletin R-3180
Issue Date 0888
R-3180 Low Range
Differential Pressure Controller
Features
• High Degree of Accuracy
and Linearity in Extremely
Low Differential Pressure
Applications
• Minimum Hysteresis
• Protective Enclosure
• No Static Pressure
Transmitters or Special
Sensing Tips Required
The R-3180 is a reliable low
range differential pressure
controller designed to accurately
measure a differential pressure
and convert this measurement
into a proportional 1 to 17 PSIG
(7 to 119 kPa) output signal.
The R-3180 is suitable for a
variety of control applications,
such as preventing cross
contamination from ajoining
referenced rooms or cooridors.
The R-3180 is therefore a good
choice for pressure control of
clean rooms, operating rooms,
or laboratories.
Operation
The R-3180 senses space static
pressure in two locations. The
difference between the two static
pressures is compared to the
controller set point. The set
point is adjustable from 0 to
0.1 in. WG (0 to 25 Pa). As the
Specifications
Fig. 1: R-3180
Differential Pressure Controller
sensed differential pressure
between the high and low inputs
increases above the set point,
an internal mechanism
proportionally increases the
output signal of the R-3180. As
the differential pressure
decreases below the set point,
the output signal decreases
proportionally.
By reversing the orientation of
the sensing lines, the R-3180
can be utilized for reverse acting
applications.
Application and Drawing
Identification
The performance specifications are nominal and conform to acceptable industry standards. For
application at conditions beyond these specifications consult the local Johnson Controls office. Johnson
Controls, Inc. shall not be liable for damages resulting from misapplication or misuse of its products

Installation
An integral mounting flange is
provided for surface mounting
the R-3180 using two #8 sheet
metal screws (field furnished).
The unit is factory calibrated in
the vertical position; therefore,
the unit must be mounted within
15 angular degrees of the
vertical position as indicated in
Fig. 2, on a vibration-free
surface. The sensing line
lengths must not exceed the
values noted in Table 1.
Calibration
1.
With the R-3180 installed in
the vertical position, furnish
20 psig (140 kPa) to the
supply "S" connection and
wait 24 hours.
2.
Hook up a test divider
circuit as shown in Fig. 4
and disconnect the low side
reference.
3.
Turn the selector switch
knob to apply air to the
adjustable restrictors.
4.
By adjusting restrictors #1
and #2, cause the
magnehelic gage or
manometer (gage #3) to
read the desired space
differential pressure set
point.
5.
Utilizing the set point
adjustment screw shown in
Fig. 5, bias the output of the
R-3180 to the desired value
(typically midrange of the
controlled device).
6.
Disconnect the test divider
circuit and reconnect the
sensing lines and output to
the controlled device(s).
Repair Information
Field repairs must not be made.
For a replacement R-3180,
contact the nearest Johnson
Controls branch office.
