Executive Letter from the Energy and Water Conservation Manager 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 manager of the Energy and Water Conservation (EWC) program, my 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 energy and water audit work conducted at the Belo Media Center (BMC) building on campus during February – May 2014. The building has been part of the UT landscape since 2012. A good candidate for our first pilot energy and water audited building, BMC is comparable to similar buildings, and the pilot had the support of the building manager, Jason Shoemaker. Of course, none of this could have happened without the support of all the occupants at BMC and assistance from other divisions within Facilities Operations and Maintenance (Zone 2 and 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. Ana Thiemer Manager, Energy & Resource Conservation Manager, Replacement & Renewal

Executive Summary: The University of Texas at Austin Energy and Water Conservation Program (EWC) is part of UT’s Facilities

Operations and Maintenance division within the Facilities Services department. EWC’s mission is directed by

the President’s Sustainability Steering Committee to reduce demand side energy and water consumption for

education and general buildings on campus by 20% by the year 2020 (baseline 2009).

This document summarizes the Energy and Water Conservation Program’s energy and water audit of the Belo

Media Center (BMC) conducted March – July 2014 and includes the following:

Next steps for BMC and EWC

Below is a brief summary of audited areas and key Energy Conservation Measures (ECMs) with next steps and

future recommendations. Details are included in the full report. At this time, information on avoided energy

and costs associated with this project is showing a trend towards avoided energy use and cost. EWC receives

this energy data on a monthly basis through Utilities Energy Management’s ENURGY, and the last reported

month was May. Below is a graph showing the impact- note that typically UT facilities increase in usage during

the summer due to increase cooling, but in the case of BMC, the usage is decreasing. Feel free to contact us at

Plug Loads -Audio/ Visual Equipment

Technology Services staff for the College of Communications proactively manages energy of their equipment.

EWC staff logged specific pieces of equipment for Technology Services and made recommendations for adjusting schedules.

Technology Services will continue working with EWC to gather pre-/post-audit data using WattsUp Pro, etc. to inform purchasing decisions for future spaces. EWC recommends that all A/V equipment be scheduled during holiday break and summer sessions.

KUT Audio/Visual Equipment

KUT independently manages their A/V equipment.

EWC program had no recommendations specific to KUT A/V equipment.

EWC will serve as a resource to KUT staff, if requested.

Water - Fixtures

Water fixtures in lavatories have sensors and kitchen/break rooms have low flow aerators.

All fixtures’ gallons per minute were as designed.

No future recommendations.

Water- Toilets All toilets have sensors and and are designed to use 1.28 gallons per flush (gpf).

Some toilets had a higher gpf than designed. Work orders were submitted, but maintenance staff determined that they cannot be adjusted.

No future recommendations.

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 BMC will continue the

relationship with the new building manager and occupants, sending quarterly newsletter to engage the staff

and drive culture change, and having technical staff monitor building performance--especially during seasonal

shifts.

Energy and Water Conservation Audit Details

Justification for BMC: EWC prioritized several buildings before focusing efforts on BMC. The prioritization

included:

ranking buildings by their energy utilization index (MMBTUs/GSF),

assessing existing building condition,

reviewing previous results of ECMs conducted in buildings, and

considering support from building manager and occupants.

The table below shows BMC’s Energy Utilization (EUI) Index rank in comparison to other buildings (Table 1).

BMC is approximately three years old and no

major renovation or mechanical issues were

known. In addition, no funding is tied to the

EWC program efforts and newer equipment with

an efficiently designed building envelope (based

on Leadership in Energy and Environmental

Design) removed high intensive capital needs

from the audit. Other than staff time and

expenses for hosting open houses this audit was

completed without any expense to The

University of Texas at Austin.

When previous ECMs were attempted at BMC,

such as scheduling the conditioning system and

hot/cold deck resets the team found that the

building was not responding well (interior

spaces were not recovering to a comfortable

temperature set point), even though the systems

were designed for energy conservation.

Even though previous ECMs had not worked as anticipated, the building manager supported the university’s

effort in conserving energy and water on campus. The energy steward assigned to BMC and the building

manager developed a good relationship and both embodied the desire for the building to perform as

designed. Both understood that occupant education and outreach was equally important for the effort to be

successful.

Audit Process and Timeline: Once BMC was selected mid-February of 2014, the team outlined their plan

which included the five broad steps, below. The team worked hard to maintain a short timeframe for the

steps, but it should be noted that for future buildings more time should be allocated to the field audit and

HVAC controls analysis.

5. Report Findings and Continued Monitoring

Summary of audited areas and energy and water conservation (ECMs/WCMs) actions taken: Selected

audited areas and methodologies were based on ASHRAE Energy Audits I & II, as well as peer reviewed case

studies to inform our process. Staff was assigned as leads to specific areas based on their skill sets, and the

team was able to identify issues quickly and put plans to action immediately. Below are the findings of the

audit and actions taken for the following:

1. Utilities

2. Maintenance

3. Building Automation System Controls

4. Lighting

5. Plug Loads

6. Water

7. Outreach and Communications

1. Utilities:

The building consumes three main energy sources - chilled water for cooling, steam for water and space

heating, and electricity for lighting, plug loads, and mechanical equipment. All sources are generated by The

University of Texas at Austin, Hal C. Weaver Power Plant and campus chilled water loop. The university pays

for all the power to support these operations of BMC and the clients are unaware of associated cost. When

initially compared to campus buildings in terms of total annual energy consumption per square foot, BMC

ranked as the twelfth most energy intensive building at nearly double the campus average and almost three

times that of comparable buildings [Table 1, page 6].

A more in-depth analysis of the BMC utility data revealed several inaccuracies in the utility meters. Chilled

water consumption was being calculating at four times the actual consumption and accounting for electrical

submeters was being doubled. Working closely with Utilities and Energy Management (UEM), they quickly

adjusted the meters, which resulted in a correction that led to a 68% reduction in billed energy cost and

consumption (Table 2).

After adjustments, BMC’s energy intensity is now below

the total campus average, although still above average

for similar buildings and 30% over the original design.

The two graphs below display the associated costs previously billed per energy

source and the actual annual energy cost after being adjusted.

2. Maintenance:

Technical staff identified several issues with equipment during the audit and based on customer feedback and

previous work order history. EWC found issues in five key areas:

Failed thermostat controls

Failed sensors (CO2)

Variable air volume boxes not controlled properly

Dampers that were stuck

Flow and sensors reading incorrect data

All maintenance issues were sent to Zone 2, which has begun work on the maintenance items.

3. BAS Controls:

The Building Automation System (BAS) for HVAC controls at BMC is Siemens. Three outside air handler (OAH)

units serve the building. Two of the three systems have the same design in which the outside air handler is

connected to the inside air handler unit that heats/cools the designated area. These two designated areas are

KUT 1 and KUT 2. The third outside air handler unit connects to five inside air handlers that serve the rest of

the building.

The engineering team evaluated and changed the sequence of operation to determine the optimal settings for

the building, analyzed current temperature set points and adjusted based on campus standards, and reviewed

and adjusted ventilation in all spaces based on ASHRAE standards.

Sequence of operations. BAS essentially looks at all points in a mechanical system and adjusts ventilation,

heating and cooling, and all components of the mechanical systems to meet the needs of conditioning the

building. The audit found that the sequence of operations for all air handlers did not allow optimal operation

of the building. Staff removed programming points in specific scenarios to allow better operations and the

ability to further optimize the system.

Temperature Set Points. Several temperature set points were adjusted throughout the building, causing

overall inefficient operations of the air handlers. Examples were mechanical and electrical rooms with set

points 68 degrees or below. Working with the campus occupants, adjustments were made to spaces where

temperature cooling and heating set points were outside of optimal operating ranges.

Ventilation. All commercial buildings are supplied outside air to provide necessary indoor air quality for the

facility. Ventilation air change rates per hour (ACH) are set by ASHRAE, and ACH is a measure of how many

times the air within a defined space is replaced. Based on design minimum airflow, the team calculated

existing ACH for spaces at BMC. Many of the spaces were receiving minimum ACH higher than required

compared to ASHRAE standards. Observation of several spaces determined if the load was being adequately

met and, if so, new minimum airflows were established to better meet ASHRAE standards.

4. Lighting:

BMC’s lighting fixtures all meet university design standards for efficiency, so the team looked to the lighting

controls and lighting schedules as the main opportunities to optimize operations. There were three key areas

for lighting: occupancy sensors in individual offices; lighting controls in common areas; and lighting controls in

auditoriums.

Occupancy Sensors. The as-built drawings/submittals showed that the sensors’ settings were installed with

the following factory defaults: Pole 1 for the overhead light, automatic ON/OFF with a 10 minute time delay

before switching the light OFF. Pole 2 for the task light plugged into the controlled electrical outlet, manual

ON with a 10 minute time delay before switching the light OFF. A few sensors were checked and confirmed.

EWC was contacted by an occupant stating that the overhead light did not go OFF automatically. EWC

responded and changed the microphone setting of the sensor; it now operates correctly. A flyer explaining

the sensors’ default settings and how to request changes to those settings was created and distributed to

building occupants so they are able contact the team if adjustments are requested (Appendix A).


10

Common Space Areas. Common areas are controlled by a Leviton system. An automatic time-clock controller,

located on each floor, operates the lights in each floor’s lobby and corridors. Override switches located in

these same areas are disabled during the controller’s ON period but enabled during the OFF period. With the

current programming, the fixtures can be overridden for one hour at a time and continue to be overridden

until the next ON cycle occurs. The schedule settings were changed by EWC staff to optimize the amount of

hours the lights are OFF. Original settings were set for the lights to come ON at 4am. The new settings are ON

at 7am and OFF at 8pm EXCEPT for the first floor, which is ON at 6am. The controller’s schedules for the KUT

spaces were not modified.

Auditorium. A Crestron system controls the auditorium. When field auditing the space, the team recognized

that the command for lighting when someone entered the space called for all lights on. EWC staff noted this

observation during their Initial Findings presentation to department heads and the Assistant Director of

Information Technology said his team could make the change to a lower lighting setting during initial

occupancy. The change was made and now when motion is detected, preset 1 is triggered, which uses

significantly less power since no incandescent stage lights are turned on using this preset.

5. Plug Loads:

Plug load is the energy used by products that are powered by means of an ordinary AC plug. For the purposes

of this audit, plug loads were limited to items such as electronics, appliances, media equipment and personal

items. Larger items such as HVAC equipment and elevators were excluded. Lighting was also separated into a

dedicated section. The plug loads found in BMC are easily categorized into three different groups: office

spaces, audio and visual (A/V) equipment, and KUT equipment. Each category is also the responsibility of

different groups within the building.

Office Spaces. Per the request of senior staff at BMC, the team counted the number of personal printers, mini-

fridges, and space heaters found in the office spaces. As the university has no policy regarding these personal

items, the team’s recommendations are as follows:

Encourage building occupants to unplug their personal printers and use the network printers that are

available on every floor.

Encourage building occupants to remove space heaters. The need for the heaters should now be

eliminated due to corrections made with the HVAC system.

Encourage the usage of communal refrigerators and freezers to eliminate the need for personal

refrigerators.

Work with staff to promote the Power Down Assessment program, EWC’s behavior-based incentive

program consisting of personal energy audits that allow building occupants to understand their

personal energy impact.

Audio and Visual Equipment. Moody College Technology Services has taken an active interest in managing

their equipment in an energy efficient manner, and productive discussions with them led to further

suggestions. To assist EWC staff in the audit, a full equipment list was provided to ensure all items were

accounted for and EWC staff assisted IT staff in monitoring specific plug loads with WattsUpPro meters to

determine future steps. The table below summarizes the Technology Services plan, EWC recommendations,

and meter findings. A more detailed analysis can be found in Appendix B.

Future Actions

Metering Results Recommendations

Amplifiers Amplifiers are left on and there have been noise complaints in rooms with oversized amplifiers.

Consider connecting to relay power (capital expense) or downsizing to smaller equipment.

A/V rooms with medium-sized amplifiers consume roughly 393 fewer kWh per year than A/V rooms with large amplifiers.

Install smaller amplifiers in appropriate rooms for future projects. It is not financially feasible to remove existing equipment or to add power relays.

Digital Displays 46”TV displays controlled by MacMinis are in sleep mode from 11 pm - 7 am.

May plan to control all displays from one computer.

Modified schedule has the potential to avoid 1053 kWh per year.*

Reduce hours of operation during summer session and turn off during winter break.

Media Consoles Media consoles are put in sleep mode at 11 pm and activated by the next user. Projectors are left on during the day to extend the life of the bulbs.

Plans to add motion detection system sleep/ shutdown to the A/V systems in all classrooms.

*See Appendix D for details.

KUT Space Equipment Loads. An inventory of KUT equipment was conducted by KUT staff. Due to the

sensitivity and 24/7 operation of KUT, this space was removed from the audit.

6. Water:

The team looked at the faucets and lavatory fixtures for the water audit. The water fixtures all met university

design standards for low flow consumption, so the team focused on operations and audit sensor response and

flow times.

Faucet and Lavatory Fixtures. Kitchen fixtures calculated ranged from 1.07 gpm to 1.88 gpm, well within

limits of low flow fixtures. All toilets at BMC are 1.28 gpf flush valve toilets triggered by infrared sensor and

urinals are waterless. Eleven toilets were close to double flow of gpfs and were submitted to Zone

Maintenance for adjustments. Zone assessed the flush valves and discovered they are not adjustable. There

are no additional water conservation recommendations at this time.

7. Outreach and Communications:

It was critical to the building manager and the team that this effort be done in a professional manner and

include key stakeholders of the building. This approach helped build reliable working relationships with the

occupants, which assisted staff throughout the audit process. The team maintained communications with

BMC occupants through open houses and stakeholder meetings, on site presence, and newsletters.

Open Houses & Stakeholder Meetings. Beginning in March, the team invited building occupants to join them

for the first open house meeting to learn about the Energy and Water Conservation Program and what the

team would be auditing. Hosting these meeting was a necessary step for the team and allowed them to

gather necessary feedback, such as areas where people were experiencing comfort issues, and meet key

people, such as IT staff. An additional meeting occurred the first of April to provide field audit results and

gather additional feedback on what the team was going to implement. This was done during the BMC

department head regular team meeting. Mid-April, an open house was set up to share the same findings and

next steps, and the final meeting occurred May 21. It should be noted that the team, and BMC key staff

agreed that in future audits three open houses (pre-, mid-, and post-audit) would better suit staff needs.


13

Newsletters. Using Mail Chimp newsletter software for

communications throughout the process assisted the team

in sending out information regarding the audit, highlighted

our student volunteers, and highlighted other campus

conservation programs that were occurring during the audit

such as Longhorn Lights Out, Earth Week events, and

Power down Assessments. Our first newsletter reached 12

occupants, and we almost doubled our subscribers for the

second newsletter distributed to 23 subscribers. Staff will

continue using this tool on a quarterly basis to inform BMC

occupants of their building progress and opportunities to participate in program initiatives.

On Site Presence. The EWC team is assigned to 103 buildings on campus, and by collectively working at BMC

as a team they were able to establish relationships with occupants just by being in their spaces and having a

better understanding of their use. Our energy steward assigned to this building will continue the newsletter

correspondence and visits with key staff as appropriate.

Caveats and Future Plans:

The BMC energy and water conservation project overall was a success for the occupants and the program

goals of reducing energy and water consumption in campus buildings. Some caveats to consider in the future

are:

Review utility data prior to building selection.

Engage the Building Optimization Team (BOT) in our work to assist on maintenance issues.

Review plug load audit process before implementation.

Reduce open house” meetings to three.

Complete maintenance items reported.

Distribute newsletter to BMC occupants when appropriate.

Continue working with staff on scheduling AHUs, IT equipment, lighting to optimize the times based on

semester and seasonal occupancy loads
