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
National
Center
for
Supercomputing Applications was
founded in 1986 by the National
Science
Foundation.
This
“center” has always been located
in Urbana/Champaign, but it
wasn’t until 2003 that a building
was
built
specifically
for
supercomputing. Prior to 2003,
it
occupied
nine
different
buildings on the UIUC campus,
and a single building in Virginia.
The building was completed in
2005 and most researchers were
able to move to this new
building. Though many of the researchers utilizing the supercomputers at NCSA are
affiliated with the University, scientists and engineers across the United States can access
these machines remotely.
The National Center for Supercomputing Applications has a gross square footage of
141,708 and is located on the north side of the campus, at 1205 W. Clark Street in Urbana.
The current supercomputers at NCSA are Mercury (10 teraflops), Cobalt (8 teraflops), Abe
(89 teraflops), and Lincoln (47 teraflops). The term teraflop is described as 1 trillion
calculations per second. Currently, NCSA is working with IBM on a new system called Blue
Waters, which is due to come online in 2011. Blue Waters will perform 1 quadrillion
calculations every second (which will be known as a petaflop).
The center focuses on helping all types of research by developing and exploring
techniques to accelerate scientific computing. The center also works to help research
communities fully exploit the extraordinary resources available on the internet with
cyberenvironments.
The following is a current timeline of the National Center for Supercomputing
Applications building and its systems:
o 2003:
Building began construction.
o 2005:
Dedication of NCSA.
o May, 2010:
The building was visited by the Retrocommissioning Team, Division of
Utilities and Energy Services with Facilities and Services of the
University of Illinois.

PLUMBING SYSTEMS
__________________
No investigation has been made of the plumbing systems as of the time of this narrative.
HVAC SYSTEMS
____________________
The building is connected to the central campus chilled water loop and has a functioning
chilled water meter presently. The steam meter resides in the basement mechanical room.
There are two significant air handling units in the building totaling 136,000 CFM which run
24/7.
There are three steam-to-water converters in located in the basement mechanical room.
These are controlled per DDC. One serves the reheat system while the other two serve the
perimeter radiation system. Each has a set of pumps.
The entire building is controlled per Direct Digital Controls, right down to the wall
thermostats and VAV boxes with reheat coils. The current system is Siemens Building
Technologies. The HVAC system at the room level is controlled per occupancy sensor, when
activated the box controls to the stat, but when unoccupied the box goes completely closed.
The entire control system can be viewed online through Siemens web graphics or terminal
server.
ELECTRICAL SYSTEMS

Figure 1: Site Plot Plan
OCCUPANCY REQUIREMENTS & SCHEDULING
__________
This building is used by graduate students and acclaimed faculty on a regular basis,
remaining in the labs into the late hours of the night and early morning. There are hours of
operation for the facility and the HVAC controls have been programmed to run according to
those schedules. Such schedules apply to the perimeter offices, while the labs are constant
volume. 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.illinois.edu/emergencyplanning/emergency.response.html
to locate telephone numbers and methods to safely encounter many emergency situations.

Building Narrative 01
INDOOR ENVIRONMENTAL QUALITY REQUIREMENTS
______
This facility requires optimum temperature control in each of the spaces where collections
are stored. The desired occupied temperature should be kept between 70 deg F and 74 deg
F depending on the season. A setpoint of 72 deg F is preferred to meet the thermal comfort
for the majority of the visitors and employees. The desired relative humidity is 50% with a
tolerance level of +/- 10%. The use of outdoor air is encouraged for adequate ventilation
and “free” cooling, as long as the relative humidity levels are not compromised.
UTILITY COST / ENERGY SAVING GOALS
__________
The primary energy saving goals for this site are to limit energy use when the building is
unoccupied, taking full advantage of reducing air flows in the offices during unoccupied
hours.
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.
If such mechanic does not understand the system, then a mechanic who does should be
contacted for assistance and training. 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. Retrocommissioning can not and will not be held responsible for system
degradation after the visiting period due to lack of follow through on the proper
maintenance.
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 – 74F zone year round and “hot” and “cold” calls minimized. 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 and
humidity levels.

Owner’s Operating Requirements 03
OVERVIEW
The controls for this building appear to be in good shape. There is a programming issue with
control of the perimeter heating system. The control valves for the humidifiers leak supply
steam to the humidifiers when there is no call for humidification.
Frank Boland
Shop 41 Rep.
Todd Nicholas
Shop 55 Rep.
Over-temperature protection was added to the hot water reheat converter (HX-1) and overtemperature protection was added to the glycol perimeter/preheat converters (HX-2, HX-3).
This building seems to be working pretty well. There are a few things I would recommend to
do here. The first thing I would do is to reprogram the perimeter heat valves to operate with
the reheat valves as I seem to think that the reheat is satisfying the room temp before the
perimeter valve gets a command to open. They both work off the same control loop which is
0 to 100%. The reheat valve works from 0 to 100% of the loop and the perimeter valve
works from 50 to 100% of the loop. In most cases I believe the perimeter valve is never
opening, and if your desk is next to the window it may be quite cold in the winter.
The next thing I would do is replace the occupancy sensors in the rooms with the better
occupancy sensor if the old ones go bad. They are a Leviton model OSW12-MOW which has
motion detection as well as sound detection. I have replaced a few with this model, and they
have worked very well. They still only have a 30 minute delay max like the other occupancy
sensors. We have found bad occupancy sensors while changing out the power packs for them
from an ODP20-070 to an OSP20-RDO. The reason for changing the power pack is the
ODP20-070 doesn’t have an extra set of dry contacts for the HVAC control. So once we hook
up the VAV box controllers to the occupancy sensors the box will keep going on and off
intermittently because the occupancy sensor is out to lunch and someone has disconnected
the light circuit from the power pack relay to keep them from going on and off. This should
have been fixed when the lights weren’t working properly.
Next, the humidifiers need to be fixed as well. I don’t think they have ever worked or the
water they are using in it is very pure. The humidifiers look brand new. When we looked at
them the tank temperatures were around 130 degrees and there wasn’t any water in the
tanks. The reason there wasn’t any water in the tanks is that the fill had been disabled on the
touch pad for the control of the humidifiers. The reason I think is that the two 2 inch steam
valves that are supplying low pressure steam to them are leaking through all the time when
the BAS isn’t calling for them to be open , thus putting steam into the AHU’s when you don’t
want any humidification, especially in the summer time.
Last but not least, I would entertain putting C02 sensors in the return air ducts of both air
handlers as to limit the amount of outdoor air that is being introduced in to the mixed air
plenum. Why bring it in if you don’t need it? I have been told this is not feasible, but I tend to
disagree. Also maybe entertain installing temperature sensors after the preheat coil as to tell
if you may have a blown diaphragm on the valve actuator or a leaking valve.

Control Diagrams
Upon initial inspection of the unit I found that 5 of the 9 housing access doors had damaged
door gaskets.
I repaired the damaged door gaskets.

While inspecting the dampers I found the Max Outside Air damper had a broken mounting
bracket and on the control shaft coupler there was a missing roll pin. With these defects on
this damper it was impossible for the damper to actuate. The motors would move but the
damper would remain in the open position.
I repaired the broken mounting bracket and a roll pin was reinstalled into the control shaft
coupler. The damper now operates properly.
An inspection of the remaining dampers revealed them to be in proper working order.
The cooling coils appear clean and free of debris, and the drain pans are clean and are
draining properly.
While inspecting the humidifier section of the unit I found that there was some missing
insulation on one of the cooling lines. The resulting condensation on this has dripped onto the
floor of the housing and has started to rust the floor.
The insulation needs to be repaired so no further damage is done to the floor of the housing.
On 24 May 2010, 1:05 P.M. I took initial CFM readings across the heating coils with the
dampers at:
Min. O.A. @ 100%
Max. O.A. @ 0%
Exhaust damper @ 0%
R.A. @ 100%
I read an average of 644FPM. This translates to 51520 CFM.

This fan is located in the basement in room 01 on the west side of the room. The supply and
return fans run via VFD’s of the Abb 800 type. The VFD minimum set points are 15 hertz. The
supply fan and return fan VFD’s are getting speed references and start/stop commands from
the BAS. Both VFD’s are sending back run status and VFD alarm status back to the BAS.
Both the supply and return fans are plug type fans and are totally controlled by the BAS
which is of the Siemens Appogee type control. There is one MEC controller that is node 20
that has 3 expansion point block controllers. All of the dampers and control valves are electric
to pneumatic control via the Honeywell type transducers that control from 2-10 vdc to 3-15
psi. They consist of chilled water valve, heating valve, mix air dampers, outdoor air damper,
min. outdoor air damper, humidity valve, and humidifier shutdown. We calibrated all of the
transducers in software as the Honeywell transducers can’t be field calibrated. We replaced
the mixed air dampers transducer on this unit. There are 2 humidity sensors on this unit,
Discharge air humidity and return air humidity sensors. We found the discharge air humidity
sensor to be bad and replaced it with a Vaisaila HMD 60U type sensor. The original sensor

was of the Siemens type 538-891 Duct RH-2-I. We calibrated all the analog pressure sensors
that consisted of building static pressure, supply air duct static pressure, discharge static
pressure, supply air pressure, mixed air static pressure, and return air pressure. We found
that all of these sensors to be out of calibration at this time. We calibrated all the digital
pressure safety switches that consisted of mix air static pressure, low static pressure, and
high static pressure. We found all of theses devices to be working properly at this time. This
fan has 3 temperature sensors that consist of supply air temp, return air temp, and mixed air
temp. We calibrated all of theses sensors and found that they were a bit off calibration, but
not bad enough to warrant a sensor replacement.

While inspecting the dampers it was found that there was a leaking positioner on the Min
Outside Air damper that effects the proper operation of this damper. Temperature Control is

An inspection of the remaining dampers revealed them to be in proper working order.
The cooling coils appear clean and free of debris, and the drain pans are clean and are
draining properly.
While inspecting the humidifier section of the unit I found that there was a section of the floor
that had begun to rust. I believe this is due to a seam on the housing floor that does not
allow the standing water to reach the drain. This problem needs to be addressed to avoid
further deterioration of the housing floor.
On 6 June 2010, 1:05 P.M. I took initial CFM readings across the heating coils with the
dampers at:
Min. O.A. @ 100%
Max. O.A. @ 0%
Exhaust damper @ 0%
R.A. @ 100%
I read an average of 370 FPM. This translates to 29,600 CFM.
The fan was running at 29.77 Hz and 54.5 Amps.
Outside air CFM was calculated by temperature difference and was at approximately 10% or
2,960 CFM.
Equipment Description Summary
Air handling unit S2 contains a minimum outside air damper, an outside air damper, a set of
mixed air dampers (a return air damper and a relief air damper), a glycol preheat coil, a
humidifier, a chilled water coil a centrifugal supply fan, a centrifugal return fan, and static

pressure safety switches that consisted of mix air static pressure, low static pressure, and
high static pressure. We found all of theses devices to be working properly at this time. This
fan has 3 temperature sensors that consist of supply air temp, return air temp, and mixed air
temp. We calibrated all of theses sensors and found that they were a bit off, but not bad
enough to warrant a sensor replacement.

This exhaust fan serves the rest rooms and break rooms. It is a mushroom style Greenheck
fan. This fan operates in conjunction with unit AHU-1 the software code states that when
AHU-1 is on, so is EF-1. Upon initial inspection (18 May 2010) of the fan I found that the
belts were in disrepair and not turning the fan. The motor was running but the fan was not
turning. I installed new belts (20 May 2010) and the fan is now running.
On 6/9/2010 I traversed the duct work for this fan and found it to be exhausting 9360 CFM.
This fan is located on the roof above room 4050D by going through door 4046 and going up
the stairs through the roof access hatch. There is a 5hp 3phase motor on this fan that starts
across line voltage via combination starter disconnect located at the bottom of the stairs in
room 5001 which is an elevator equipment room. This starter is controlled by the BAS that
will give the fan a start/stop command and receive run status from the starter. There is also
an expansion block wired from MEC node 21 in this room next to the combination starter
disconnect for the exhaust fan that the start/stop and the run status is wired to. The program
calls for this exhaust fan to start and run whenever AHU-1 has a run status input to the
controller. I didn’t find any problems with this fan other than maybe moving the combination
starter disconnect for this fan into room 4046, and possibly moving the TT switch that is
located on the fan on the roof to a better location for the persons who have to service this
fan.

This exhaust fan serves the IT lab, and is a six inch snorkel vent. At the time of inspection
(19 May 2010) I was unable to get the fan to operate. The disconnect switch is located
adjacent to the fan location in room 2003 with a hand/off/auto switch. Therefore I was
unable to take readings to determine CFM’s.

As Chuck said this fan serves a snorkel hood in room 2003 which is a computer IT room. This
fan runs via a combination starter disconnect, with a hand/off/auto selector switch. This fan
will not operate as there is a blown fuse on the 3 phase 480 volts feed into the disconnect,
therefore not letting the control power transformer to work and not letting the starter
contactor to pull in. I have been instructed to leave this fan starter as is.

This exhaust fan serves the basement mechanical room. It is a Greenheck barrel style fan. It
operates in conjunction with AHU-2; the software code states that when AHU-2 is on so is EF3. In the interest of saving energy, it may be possible change the way this fan is controlled
and have it be controlled by a thermostat that would be located in the serviced area,
therefore eliminating the need for this fan to run 24/7.
I traversed the ductwork for this exhaust fan and found it to be exhausting 5404 CFM.
This fan is located in the basement in room 01 hanging from the ceiling just west of AHU-2.
This fan runs via a combination starter disconnect that is located on the north wall in the C2
hall way just south of the relief air areaway. This starter is controlled by the BAS that will
give the fan a start/stop command and receive run status from the starter. This fans serves
the mechanical equipment room and is programmed to start whenever there is an run status
indication to the BAS controller. We may want to install a wall mount thermostat in this area
so that the exhaust fan will only run when necessary.

Ecit: 24VDC
Output: 4 – 20 ma
This system is located in the basement in room 01 on the south east side at the ceiling
elevation. The system consists of a flow control valve (supply side), an isolation valve (return
side), an flow meter, and a pressure differential pressure sensor. The flow control valve is
controlled via a electric to pneumatic transducer of the Honeywell type. The flow control valve
is controlling to maintain a 30 psi pressure differential between the supply and return chilled
water lines. The pressure differential sensor is located in the basement in close proximity to
the chilled water entrance, so I think that is why the Set Point is so high. The chilled water
system is maintaining a differential pressure of about 24 psid with the control valve 100%
open. The flow meter is of the Rosemont anubar type and is reading between 200 and 300
GPM. I suspect that the differential pressure sensor may be out to lunch and needs to be
calibrated and or replaced. We didn’t see any pressure drop across the strainer on the supply
side so we are not sure why the system won’t maintain its DP set point at this time. I
checked the open and closed limits on both the supply and return valves and they seemed to
be operating correctly at this time.

There is one heat exchanger (HE-1) with two hot water pumps on the system that
run via VFD’s of the ABB 800 type. The heat exchanger steam valves and pumps
are totally controlled by the BAS of the Siemens Appogee type control. There is
one MEC controller that is node 22 with 3 expansion point modules. The BAS is
giving the VFD’s for pumps P1 and P2 start/stop commands and speed references.
The VFD’s are giving the BAS run status and alarm status inputs to the controller.
The heat exchanger has a hot water supply temp sensor and a hot water return
temp sensor wired back to the BAS controller. The 2 hot water pumps are
redundant as only one pump should be running at any given time. If the lead pump
should shut off for any reason the lag pump will get a command to start and run to
maintain a differential pressure of 8.5 psid. The differential pressure sensor is
located on the 3rd floor above the ceiling outside of room 3102C. This sensor is of
the Setra type and it is a 0-50 psid, 4 – 20 ma device. We calibrated this device
and found it to be out of calibration and it was set up wrong in software. It was set
up in software as a 0 - 60 psid device not a 0 – 50 psid device. We corrected this
problem as well, and the sensor is reading correctly at this time. The BAS is also
controlling two steam valves for the heat exchanger. A 1/3 and a 2/3 type steam
valves that are N.O type valves. They are electric to pneumatic controlled valves
via 2 transducers of the Honeywell type that put out 3 –15 psi via 2-10 volts DC
from the BAS controller analog outputs. We calibrated both transducers and found
that they were working correctly. One steam valve has been taken out and only
the 1/3 valve transducer is in operation at this time. Not sure why that is, but it
seems to be working with a outdoor air temp of 70-90 degrees and a 120 degree
hot water supply set point. We calibrated both the hot water supply temp and the
hot water return temp sensors and found that they were a little off but working ok
at this time.

Retrocommissioning Final Report 04
Executive Summary
The Retrocommissioning Team in conjunction with Facilities and Services Utilities and
Energy Services Division completed retrocommissioning of this building for the University of
Illinois. The work 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 May of 2010. It involves a coordinated effort
between the RCx Team, Directors of Utility & Energy Services and Maintenance, DDC Shop,
Sheet Metal Shop, Temperature Controls Shop, DDC Programmers and the willing building
staff. The process included reviewing documents, conducting informal interviews with staff
and inhabitants of the spaces, performing field investigations, monitoring and analyzing
building systems, developing a master energy conservation measures list, and assisting with
selecting measures for implementation. Some of these findings were a mix of “operation
and maintenance” repairs that had estimated paybacks of three years or less and “energy
conservation projects” that were more costly to implement and therefore longer paybacks.
Additional measures sprinkled in were improvements that had potential energy reduction
and equipment maintenance impacts, but the reduction estimates were based more on
experience rather than energy modeling or engineering estimates.
A two-page current summary exists on the web at:
www.fs.illinois.edu/retro/rcxcompprojects.htm
Such implementation is ongoing and these preliminary results are rewarding. This report
details the process taken to achieve these outstanding results and the encouragement to
maintain these results.

Retrocommissioning Final Report 04
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 10, 15 or more buildings. Therefore, existing heating, ventilating
and air conditioning equipment and associated equipment have been 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:

These steps take place concurrently. However, below the report shows in detail how the

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 the latest existing air
balance reports for the HVAC systems, gathering the temperature control drawings from the
shops and 3rd party installations, as well as the HVAC floor plans for quantities and sizes of
HVAC units. Shop drawings and energy data were also gathered and reviewed by the RCx
Team.
Site Assessment
The next step was to conduct the site assessment. Questions were asked to ascertain the
facility’s operating condition. Where specific known challenges were, what maintenance has
been performed, and so on.
Many weeks were spent in the building investigating each piece of HVAC 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. 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 with direction from Mr. Kent Reifsteck, Director of Utilities and Energy Services.
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.

Retrocommissioning Final Report 04
Verification of Savings
The data shows that the solutions implemented have had serious impacts on the amount of
energy consumed and a payback of thousands of dollars. Data was collected over the last
year in energy usage and has been compared to this year after the RCx Team visited.
Charts of the energy reduction are frequently updated at the Retrocommissioning website at
www.fs.illinois.edu/retro under “Projects” and then “Completed Projects”.
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. After the Team leaves, the building is once again under the jurisdiction of the
Facility Operators, Route Mechanics and Campus Administration. They bear the
responsibility of continuing 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 will 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. F&S prides itself in offering this service to the campus.
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.

The National Center for Supercomputing Applications unites researchers
with supercomputing needs or experiments on the Champaign-Urbana
campus. The building was originally built in 2005. The building is home to
multiple supercomputers that are capable of teraflop calculations. Various
clubs and school events encouraging mathematical and technical advancement are welcomed at the facility. There are two VAV air handling
units that condition the entire four story building along with dedicated
computer room units (CRUs). The building’s cooling needs are met by the
campus chilled water loop, while the heat in the building is provided by a
combination campus steam and hydronic system. Building controls are
Siemens MECs.

Meter was replaced for optimum results.
•
A bypass around the chilled
water meter was installed to
allow for uninterrupted cooling
to the supercomputer rooms
* 220 PEOPLE OCCUPY BUILDING AT ONE TIME.
Retrocommissioning Specifics & Results
The air handling units (AHUs) providing air conditioning were maintaining space conditions 24/7/365, with a setback sequence in place. The
primary energy conservation method was connecting the existing occupancy sensors to the VAV box to condition the space only when occupied. Since 90% or better have a 8am to 5pm schedule, large quantities of energy use was avoided. Independent CRUs were monitored to
guarantee satisfactory data cluster temperatures.
To maintain comfort conditions, the VAV / perimeter heat sequence
was reviewed. The radiation was not operating unless the reheat could
not satisfy the space. This led to drafty offices. The sequence was rewritten to allow the perimeter radiation to operate independently of the
reheat valve, thereby allowing the space to warm even if the VAV box
was closed. Unoccupied setbacks were limited to a 10 degree deadband
centered on the room setpoint.
