Executive Letter from the Associate Director of UT Facilities Operations &

Maintenance The University of Texas at Austin has a renewed commitment to an energy conscious campus. To fulfill this commitment we need to operate and behave in completely new ways, making energy conservation an integral part of our day-to-day operations and activities. As Associate Director of UT Facilities Operations and Maintenance, my Energy & Water Conservation (EWC) team and I have worked diligently to poise ourselves to be the catalyst for this renewed commitment to energy and water conservation. Our approach is simple:

minimize our environmental impact,

work collaboratively with the campus community,

utilize technical tools and expertise to bring about positive changes, and

shape new behaviors centered on making our campus energy efficient, while keeping in mind our university’s mission and the safety of the campus.

Our long term goals present challenges that are substantial, multifaceted, and systemic. Put simply, our goals demand innovation, accountability, and a departure from “business as usual,” not only for campus, but for us as well. This report is an overview of the commissioning effort conducted at the Gates Dell Complex (GDC) building on campus during August 2014 – April 2015. The building has been part of the UT landscape since 2012. Of course, none of this could have happened without the support of GDC building management staff – Patti Spencer, Matt Larson, and Matt Walker – along with all the occupants at GDC and assistance from other divisions within Facilities Operations and Maintenance (Zone 1 and the Building Analysts Team). We thank you for your continued support of our program and look forward to working with you in the future. Energy and water conservation is continuous, it takes small changes to make a big difference, and it all begins with you. We welcome your suggestions, comments, and ideas to make a positive difference. Dan Clairmont Associate Director, Facilities Operations & Maintenance

Results

Since this is a newer building, accurate utility data exists back through fiscal year 2014. As of the writing of this report, the latest utility data was used, which extends through February 2015. Implementation of energy conservation measures started during the month of October 2014. Therefore, current results include four months of accurate data. In the four months since energy conservation measures began, GDC has seen an average utility reduction of $12,789.68 per month in comparison to the same calendar month in the previous fiscal year. Thusfar, the largest monthly reduction from year to year is $18,678.99, occurring in February 2015, which is also the most recent month with released utility data. We are estimating that the annual cost avoidance will be approximately $250,000 and the cost for out of house services was $15,000. The percent cost avoidance during the four month measurement period per utility is as follows:

46% avoidance of chilled water use

6% avoidance of electrical energy use

49% avoidance of steam use


4

Through February 2015, the measured average daily energy cost avoidance was $825.40.

AHU and BAS Systems

New & Enhanced HVAC Building Automation System (BAS) Programming

EWC worked with the university’s BAS analysts and the controls contractor to adjust existing programming

and add new program sequences to maximize building energy efficiency. All of the energy conservation

measures were done utilizing the existing controls infrastructure.

Terminal Level Improvements

Expand temperature dead band

GDC was designed to maintain a temperature dead band of 70-74 degrees where the damper opens to

introduce more air if the room temp goes above 74 degrees, and the reheat valve opens if the room

temperature goes below 70 degrees. We changed the temperature dead band values to 70-76 degrees in

under-utilized spaces, storage closets, and corridors where occupant comfort is less of a concern. The specific

boxes that were adjusted can be found in Appendix A – Expanded Temperature Band.

Disable sliders

The room thermostats in GDC have sliders so occupants can adjust the temperature dead band by two

degrees up or down. While this works well in individually zoned offices, large auditoriums, corridors, and

under-utilized spaces, unchecked slider adjustments can drive entire air handler unit (AHU) systems and waste

significant energy. For example, we found an AHU operating at its maximum static pressure set point and an

unnecessarily high fan speed to try to cool a single telecom room down to 70 degrees. Once we disabled the

slider at a cooling set point of 75, the damper closed off and the AHU fan slowed down. For our operational

record, Appendix B - Enabled Sliders shows the variable air volume (VAV) boxes where we left the slider

enabled for individual adjustment. All others are disabled.

Dueling boxes

Several of the larger teaching auditoriums and computer labs have two or more variable air volume (VAV)

boxes serving a single space. In many cases the boxes are battling each other (i.e., one is in cooling and the

other is reheating). To solve this problem we programmed a single temperature dead band set point for the

room (i.e., 71-75 degrees) and averaged the temperature sensors so that the boxes are responding in unison.

Adjust Minimum Space-Air Volume

We found several rooms were receiving more air than required by the American Society of Heating,

Refrigerating, and Air-Conditioning Engineers (ASHRAE) ventilation standards and by the heat load in the

space. VAV boxes serving these rooms were using reheat to warm up the large volumes of air even during the

hottest periods of the summer. A list of rooms where we decreased the minimum air flow rates to better

match the needs of the space are in Appendix C – Adjusted Minimum and Maximum Air Flow Rates.

AHU and Heating Hot Water Sequence Improvements

AHU Supply Air Temperature Reset

The original supply temperature reset sequence provided by the design engineer reset the supply air

temperature upwards as outside air temperature decreases. Since there are outside air pretreatment units

addressing the majority of the latent load and there is zone-level feedback, we adjusted the sequence to be

more aggressive. The new sequence allows the supply air temperature to reset all the way up to 65 degrees as

long as all spaces are less than 76 degrees and return air humidity is under 55%. Significantly less chilled water

and reheat hot water are being used due to this change in programming.


7

AHU-3 supply air temperature set point operates at 65 degrees most of the time after the improved supply air reset was programmed and tuned.

The period of time where the supply air temperature set point was bouncing was due to a coffee shop where temperatures frequently go above 76

degrees. We removed the coffee shop terminal box feedback from the supply air temperature reset programming so it would no longer drive the

reset, and the system started maintaining 65 degrees on most occasions.

Optimum Start/Stop

Optimum start/stop is a method that turns AHUs off during unoccupied periods and lets the BAS monitor

conditions so that the units come back on at appropriate times. The BAS “learns” the amount of time it takes

for the building to return to desired room set point temperatures, depending on outdoor and indoor

conditions. This allows the system to safely turn off but still respond to extreme conditions overnight and

meet comfortable conditions before the occupants arrive in the morning.

Economizer

An economizer sequence takes advantage of conditions where outside air is cool and dry and can be used for free cooling. Similar to other buildings at the university with pretreatment units, the economizer mode will be on when discharge temperature of the outside air unit is below the discharge air temperature of individual air units and when outside air temperature is between preheat and cooling set points (i.e., 50 and 55 degrees). The sequences of operation language for all of the ECMs mentioned above can be found in Appendix D – GDC Enhanced Sequences of Operation.

Continuous Commissioning

Rogue Zone Diagnostics

To help facilitate building maintenance and keep a high level of energy efficiency moving forward, rogue zone diagnostics were implemented to identify VAV boxes which are exhibiting symptoms of failure. The causes of these failures are varied, and may include:

Improper thermostat placement (e.g., next to a heat source)

Leaking valves

Failed valve actuators

Failed damper actuators

Failed sensors

The criteria we are using in the BAS to flag rogue zones are listed below:

Reheat valve is open above 80% for more than 2 hours and the outside air temperature (OAT) is above

40 degrees

Space temperature is less than 1.5 degrees below the heating set point for more than 2 hours and the

outside air temperature is above 40 degrees during terminal box occupied hours

Space temperature is greater than 1.5 degrees above the cooling set point for more than 2 hours

during terminal box occupied hours

Damper position is above 95% for more than 2 hours and the outside air temperature is below 100

degrees

Lighting

The majority of lighting in GDC is controlled by the Square D Powerlink system and rooms such as classrooms

and meeting rooms are controlled by the Crestron system. Private areas of the building, such as offices and

restrooms are generally controlled through a combination of light switches and occupancy sensors. For the

purposes of this audit, the Square D system was evaluated to determine how best to optimize the lighting

controls in common areas, mechanical/electrical rooms, and storage rooms.

To evaluate the current lighting system, maps of the building were created to define each lighting circuit, its

schedule, and the locations of override switches. After consulting with building occupants on various needs,

the following changes were made to the Square D system:

Input switch schedules were matched to the schedule of the zone it controls. This allows for manual

ON/OFF control of lights in common areas when the lighting schedule is OFF. The existing override

schedule was removed from the programming.


9

Timers of 30 minutes to 2 hours were added to input switches to automatically turn off lights after a

specified time period. Previously, the lights remained on indefinitely when the input switches were

used.

An office schedule was created for the north and south side 2nd floor offices that shortened weekday

lighting schedules and keeps lights off on weekends unless the input switches are used.

Storage rooms on the south side first floor were taken off of schedules to be manually operated by

input switches.

All atrium floors were matched to the same interior schedule.

It should be noted that circuits in GDC often have override zones that allow for modification of specific circuits

without affecting other circuits within the same zone. This can allow for temporary schedule changes that do

not involve more complex programming. However, we recommend that more permanent schedule changes

should not use the override zone to avoid confusion.

Lastly, it was noted that daylight harvesting was not included

in the central atrium and this area is often brightly lit with

natural light. A future project could be to investigate this

technology to allow for light dimming.

Detailed lighting maps (Appendix E) and current schedules

(Appendix F) are located at the end of the report and will be

distributed to the building management and zone

maintenance.

Plug Loads

General An inventory of all equipment (desktops, laptops, printers, AV equipment) is kept by the building management

team. All equipment purchases must go through this department.

Server Rooms There are three server rooms inside the building with a total of seven servers. Each server room has its own

cooling unit. EWC recommends these rooms to be evaluated to adjust to a higher temperature set point

where feasible.

Audio-Visual Equipment A/V equipment consists of plasma televisions, projectors and document cameras. The current A/V power

management procedure is when a lecture or meeting concludes, the user logs off. Logging off signals the

equipment to shut down. When the building closes at midnight, building operators (paid interns) are

responsible for logging off and shutting down any A/V equipment that is left on.


10

Although the A/V power management policy requires the user to log off after a lecture or meeting, this

practice is hard to enforce. So, it is common for users to not log off after a lecture or meeting concludes.

Thereby, the A/V equipment is potentially left on all day and evening until the building operators check on the

rooms to turn off everything at midnight.

Since most of the rooms with A/V equipment do not have occupancy sensors, the capability of tying the shut-

down function on the A/V equipment is limited. EWC has given Computer Sciences a “Log Off” image so they

can load it on their computer as a reminder to log off after a meeting or lecture.

Computers and Printers in Labs and Offices There are approximately 400 machines that are managed by the IT staff. Roughly half are desktops and the

other half are laptops. The staff averages 3-4 desktops and 1.5-2 laptops per person. Current policy for users is

to log out when the computer is not in use. After 15 minutes of no activity, the computers and monitors will

go into sleep mode, per the default settings. The monitor’s default setting is a black screen with no screen

savers. Power management for computers can also be remotely controlled.

The IT retirement policy for computers is approximately every four years. There is currently no policy to look

for more efficient machines when purchasing new equipment. EWC recommends to purchase computers that

are ENERGY STAR® certified. More information can be found at:

http://www.energystar.gov/products/certified-products/detail/computers

The majority of the printers in the building are network printers; very few are individual printers. All printers

are set-up to go into manufacturer’s energy saver mode settings.

Digital Signs There are 21 digital signs that are centrally managed. Current practice is for the digital signs to stay on 24/7

because there are a number of events that occur over the year and there are occupants in the buildings after

hours. Presently, Computer Sciences staff are evaluating the energy reduction of turning off 10 digital signs in

the two main offices on the second floor. A kWh sample from the 10 digital signs will be taken using watt

meters. This data will be used to determine how to move forward.

Also, since only computer science majors are allowed after the building closes to the public, EWC suggests to

turn off all other non-essential signs between the hours of midnight to 6am since the only personnel entering

and leaving the building are already familiar with information displayed on these signs.

Additional Topics GDC Staff asked about energy savings or power benefits regarding virtualized servers vs. having information

stored locally. EWC will have to conduct further research on this topic and share their findings.

Water

EWC conducted an audit of all the bathroom lavatory faucets, showerheads, and toilet and urinal flush valves.

All lavatory faucets are manually operated. Each one was tested by using a measuring cup and stop watch.

The subsequent flow was calculated to determine if it did not exceed the Campus Standard of 0.5 gpm. All

faucets passed the test.

Using the same test as the lavatory faucets, showerheads were checked and found to have a flow not

exceeding 1.5 gpm. The Campus Standard is 2.0 gpm.

Toilet and urinal flush valves are manually operated. Each flush valve was tested by recording the amount of

time the valve was open. The subsequent gpf was then calculated based on flow rates and valve time open.

All but 5 (out of 94 total flush valves) were within tolerable range of the Campus Standard of 1.28 gpf for

toilets and 0.5 gpf for urinals. A work order was submitted to correct the 5 deficient valves.

Future To continue optimizing this building, the relationship between EWC and the occupants, with support from

zone staff and analysts, will continue. Specifically, the Energy Steward assigned to GDC will continue the

relationship with the building management staff and occupants and monitor building performance.

minimums (10/20/2014 As-Built Correction set). Correcting the minimum air flow rate in the BAS improved

system efficiency and/or comfort in the space. All others were adjustments from the scheduled minimum air

flow rates to improved rates that better met actual space requirements.

Appendix D: GDC Enhanced Sequences of Operation

Static Pressure Reset for OAHU-1 & 2 The control system shall reset outside air handling unit static pressure set points (adjustable) from their lowest

to their highest value as the most open damper of the AHUs associated with the OAHU goes from 65% to 95%

open (adjustable) with a linear relationship in between. Include a graphic showing the linear fit table on the

associated OAHU page.

Supply Air Temperature Reset at AHU-1, 2, 3, 8, & 9 The chilled water valve should modulate to maintain the cooling air discharge temperature set point. The

cooling discharge set point shall reset from 55 degrees to 65 degrees, based on the temperature of the VAVs

associated with the AHU and the return air relative humidity (RH) at each AHU. If the maximum space

temperature is equal to or less than 76 degrees, and the return air RH is equal to or less than 55%, then

increase cooling by 1 degree to a maximum of 65 degrees. If the maximum space temperature is greater than

76 degrees, or the return air RH is greater than 55%, then decrease cooling by 1 degree to a minimum of 55

degrees. All values are adjustable.

Economizer Sequence for AHU-1, 2, 3, 8, & 9 When in economizer mode, incrementally increase outside air flow to its maximum value to maintain a mixed

air temperature set point prior to air entering the chilled water coil. The mixed air temperature set point

should be two degrees lower than the coil discharge set point. Otherwise, incrementally decrease outside air

flow down to a minimum dictated by CO2 levels.

Economizer mode ON if ALL of the following are true:

Outside air unit cooling and preheat valves are closed

Discharge temperature of the outside air unit is below the discharge air temperature of the individual

air unit
