EXECUTIVE SUMMARY

Governor Rick Perry implemented executive order RP 49 on October 27, 2005, requiring

each state agency to submit an Energy Conservation Plan to the Office of the Governor

and the Legislative Budget Board no later than December 1, 2005. The executive order

states “Each state agency shall develop a plan for conserving energy and shall set a

percentage goal for reducing its usage of electricity, gasoline, and natural gas.”

Each state agency shall report back to the Office of the Governor and the Legislative

Budget Board with goals achieved and ideas for additional savings on a quarterly basis.

The first quarterly report shall be due no later than April 1, 2006. Also, each state agency

shall post its report in a conspicuous place on its internet site for public inspection.

Texas A&M‟s September 2010 Update to the Energy Conservation Plan is provided

following this executive summary and is formatted in accordance with the guidance

provided by the Office of the Governor.

Texas A&M‟s Energy Conservation Plan continues with its six-year energy reduction

goal to reduce the Energy Use Index from 269 in FY06 mBtu/GSF to 225 mBtu/GSF in

FY12, representing a 16.4 percent reduction in energy consumption over six years. This

goal represents an annual EUI reduction of 2.7 percent. Many of the initiatives presented

in the December 2005 report have been completed or are moving forward and energy

conservation remains a top priority. As of September 2010, the campus Energy Use

Index is 239 mBtu/GSF, only 6% from meeting the 2012 target of 225 mBtu/GSF. The

FY12 EUI is currently projected to be 216 mBtu/GSF which will meet and exceed the

target set in 2005.

Texas A&M‟s Fleet Fuel Management Plan continues with its goal to reduce fleet fuel

consumption by three percent per year. New fuel conservation signs have been posted at

the fuel pumps, implementation continues on the use of biodiesel and adding additional

hybrid vehicles to the fleet continues.

Texas A&M‟s September 2010 Update to the Energy Conservation Plan presents updated

information on the subject of purchased natural gas, electricity and motor fuels. This

update also provides information on the status of initiatives that were presented in the

December 2005 Energy Conservation Plan, as well as any new initiatives to reduce the

consumption of energy, water or motor fuels.

Utility Assessment Reports

In May 2005 the Utilities & Energy Management Department initiated a plan to

investigate opportunities to reduce energy consumption in buildings at Texas

A&M University. This utility assessment investigation was titled “Energy

Consumption Reduction Initiative Assessment” (ECRIA). The purpose of this

investigation was to identify energy saving opportunities in buildings, prioritize

the evaluations, and provide estimated cost, savings, and simple payback.

Opportunities identified from this report were categorized into two initiatives,

one short term the other long term. The short term initiative identified energy

saving opportunities in 63 buildings that cost less than $5,000 to implement,

which are being addressed using current operating budget. Other initiatives

identified energy saving opportunities in 71 buildings that cost greater than

$5,000, to be implemented using capital funding.

Of the original 63 ECRIs identified in the less than $5,000 category, only 16

remain to be completed. A description and a status update is presented below:

UTILITY ASSESSMENT REPORTS (CONTINUED)

A second ECRIA initiative identified long term energy saving opportunities in

71 buildings that cost greater than $5,000 each to be implemented.

Previously, a funding source had not been identified and secured to implement

these projects. In December 2009 and again in April 2010, Texas A&M

requested and received approval for funding from SECO to implement a $15.1

million Energy Consumption Reduction project using Siemens as the ESCO.

The scope of the project includes upgrading Building Automation Systems

(BAS) and lighting which will include some of the ECRIs over $5,000

identified in the original 2005 document. This scope of work will be

implemented in (19) teaching and research facilities that total over 3.3 million

GSF. In addition to BAS upgrades, the lighting in all five campus parking

garages will be retrofitted to a higher efficiency fixture and other lighting

upgrades will be performed in some of the buildings receiving BAS upgrades.

Energy Engineering Associates, Inc. (EEA) was hired by the university in

November 2005 to implement two lighting upgrade projects. EEA surveyed

and documented existing building lighting and performed energy analysis to

determine project savings, cost and payback, and produced an energy

assessment report in the SECO format. The energy audits were reviewed,

prioritized and prepared for contractor bids. Amtech Lighting was selected as

the contractor. Lighting retrofits began in June, 2008 and as of September

2010, all lighting retrofit projects that were part of this scope have been

completed.

Finance Strategy

20

Finance Strategy

Funding for approved energy projects are financed by the Utilities & Energy

Management (UEM) operating budget, University Division of Finance, and the Texas

LoanSTAR (Saving Taxes and Resources) Program, or other loan programs.

Texas A&M currently has two LoanSTAR energy conservation loans outstanding, both

for lighting retrofit projects. The first is for $1.7 million which replaced inefficient lamps

and ballasts in 31 buildings (2.9 million square feet), with a payback of 5.6 years. This

loan will be paid in full in August 2011. The second lighting retrofit loan, for $1.3

million, replaced inefficient lamps and ballasts in 11 buildings (1.6 million square feet)

with a payback of 5.6 years. This loan will be paid in full in August 2012.

In 2009, Texas A&M University submitted a request for shared funding of a Combined

Heat and Power (CHP) Project, and in 2010, the U.S. Department of Energy (DOE)

awarded a $10 million grant to the university for the design and installation of a new

CHP generation system, which will very efficiently serve the growing energy demands of

the campus. Under this grant program, administered by the National Energy Technology

Laboratory, DOE awarded a total of $150 million in American Recovery and

Reinvestment Act funding for CHP and District Energy projects. The Texas A&M award

was one of only nine awards made by DOE under this program and was selected from a

very competitive nationwide pool of over 400 funding applications. Texas A&M

completed grant negotiations with DOE in June 2010 and had a final contract with DOE

in place in August 2010.

In December 2009, and again in April 2010, Texas A&M requested and received funding

from SECO to implement a $15.1 million Energy Consumption Reduction project. After

being notified of loan approval, Siemens was selected as the performance contractor.

The scope of the project includes Building Automation Systems (BAS) and lighting

upgrades which will include some of the ECRMS identified in the original 2005 greater

than $5,000 document. This scope of work will be implemented in 19 teaching and

research facilities that total over 3.3 million GSF. In addition to the BAS projects, the

lighting in all five campus parking garages will be retrofitted to a higher efficiency

fixture, together with lighting upgrades in many of the 19 buildings receiving BAS

upgrades.

Other sources of funding, as cited in the December 2005 report, remain as possible

sources of funding for future projects.

Campus Conservation Awareness Program

The Utilities & Energy Management (UEM) Department at Texas A&M University

continues to coordinate and participate in numerous initiatives aimed at reducing energy

and water consumption and improving conservation awareness among the students,

faculty, and staff at the university.

Listed below are updates on the various initiatives.

Energy Stewardship Program

The Energy Stewardship Program (ESP) was started in July 2009 as a pilot that included

(40) buildings and a total of 5.8 million GSF. ESP is designed to reduce energy

consumption and cost of operation in campus buildings by improving energy

conservation and efficiency while improving environmental conditions. With a goal of

improving service while educating, informing and enrolling building occupants, assigned

energy stewards have access to energy consumption and cost data – overall and per gross

square foot ‐ and use this data to educate themselves and others. The energy steward

meets with building proctors, facility managers, and occupants to continuously raise

awareness and improve operating efficiency.

Sustainability & Environmental Management Committee

This committee is comprised of faculty, staff, student and representatives from auxiliary

enterprises. UEM has two representatives on the committee and remains very active in

the promotion and outreach for energy & water conservation and recycling.

UEM Website / Energy Hotline

A UEM Website and Energy Hotline is maintained at http://uem.tamu.edu to:

a) promote energy and water conservation

b) provide a repository of energy and water conservation materials

c) provide “one point of contact” to report wasteful practices and recommendations

for improvement in the area of energy efficiency

In January 2009, a new UEM website was launched and continues to provide significant

information and successful results. Analysis software has been installed to better analyze

website use and effectiveness to enhance select areas with useful information.

The Energy Hotline is continuing to receive regular activity and expectations are that

contacts will increase with an expanded Energy Stewardship Program.

Energy Awareness Marketing Campaign

The university conducts an Energy Awareness Campaign that promotes good energy and

water conservation practices. Activities include, but are not limited to, Battalion

newspaper advertisements, Aggie Hotline articles, campus bus advertisements,

promotional material and promotional events, such as Earth Day and Sustainability Day

celebration and an Energy Awareness Month celebration.

23

Students, staff and faculty are encouraged to turn off all unnecessary electrical equipment

before leaving for Spring Break, Thanksgiving, and Winter Break. UEM and Facilities

Services worked with building proctors to gain approval to turn air handler units OFF

where appropriate or setback temperature setpoints. Through combined conservation

efforts over holidays since FY05, Texas A&M has avoided over $1.5 million in

unnecessary expense when compared to the 2004 baseline.

Texas A&M‟s Residence Life, with support from UEM, sponsored a series of energy

challenge competitions with the first one in October 2007. The goals of Residence Hall

Energy Challenges are to: a) raise awareness and promote greater campus involvement in

conservation while having fun, b) encourage students to “Go Green” and change their

individual lifestyles and attitudes about the need for conservation and the importance of

sustainability, and c) encourage residence hall student participation in campus energy

conservation as the „right thing to do‟ to help save money and reduce fossil fuel

emissions.

The most recent “Challenge” included goals to:

Promote individual sustainability awareness among students.

Encourage sustainability habits, particularly in new students.

Build a sense of community within halls via a competitive spirit.

Residence Halls were awarded points by resident participation in the following events:

Energy reduction as compared to the same period the year before.

Participation in a sustainability program series on how to grow a garden.

Attendance in a film series pertaining to sustainability.

Participation in recycling events.

Signing a sustainability pledge.

Submitting green tips that were distributed to all residents.

Designating an Eco Rep to work on future recycling and outreach programs.

Host a bulletin board or other display promoting sustainability and wise use of

energy.

Texas A&M‟s Dining Services continues using a converted refrigerated delivery that uses

bio-diesel fuel made with waste food oil. The waste food oil is picked up from cafeteria

operations every three weeks by Tcor Services and processed by Texas Biofuels.

24

Students

The Energy Stewardship Program includes ongoing outreach to student groups on

campus with a focus or mission specifically related to energy and water management to

address new ideas and offer a forum in which to present useful perspectives. At this time,

groups in which UEM has established communication include: The Texas Environmental

Action Coalition, the Environmental Issues Committee of Student Government,

Residence Hall Association (RHA) and the American Society of Mechanical

Engineering. Each group is concerned with some particular aspect of the Energy

Management Program. A number of groups on campus provide a valuable resource for

information on new developments in the field. In addition, each group and its members

are kept abreast of the activities and progress by the university.

Academic

Texas A&M is fortunate to have distinguished faculty in the area of energy management

and in accompanying fields such as environmental design, mechanical engineering, etc.

UEM has established relationships with individuals from each of these disciplines.

Interactions include: UEM presentations, tours of building retrofit projects, open forums

on specific topics that are pertinent to a phase or project of UEM, and joint participation

projects.

Non-State Funded Enterprises

There are 31 Non-State Funded Enterprises on the campus. These include the Residence

Halls, Food Services, Athletics, Transportation Services, Campus Bookstore, and others.

These Non-State Funded Enterprises are self-supporting businesses that purchase their

utilities from UEM and are billed monthly based on actual cost.

In the past, the Non-State Funded Enterprises were invoiced for utilities based on a

combination of profiles, square footage allocation, or estimates. Revenue-quality utility

metering has been installed in all major buildings on campus and UEM is now billing

these customers for utilities based on actual consumption and the allocation of space used

in their assigned buildings. Direct billing promotes energy conservation as well as

encourages the customers to upgrade their facilities with technologies that improve

building operating efficiency.

25

Building Construction Standards

UEM actively participates on new building project review committees and ensures that

energy and water conservation remains a priority throughout the building design and

construction process. In 2009, Texas A&M made the decision to require that new

buildings be designed and built to LEED Silver standards, but without going through the

certification process . Recent buildings completed using this standard include:

Interdisciplinary Life Sciences Building (ILSB), Texas Institute for Preclinical Studies

(TIPS), Texas Transportation Institute (TTI) expansion, and Mitchell Physics buildings.

The Emerging Technology & Economic Development (ETED) building currently under

construction will also be built using LEED Silver standards.

UEM has engaged Burns McDonnell to develop a Utilities & Energy Management

Master Plan. The deliverables of the Plan will be:

• identify operational and functional issues and priorities that require capital renewal

or investment in the existing utility infrastructure and building energy systems to

replace unreliable or inefficient equipment and upgrade systems to meet future

projected requirements.

• provide recommendations for infrastructure expansion or upgrades and define

comprehensive design guidelines to be followed for projects that will maintain,

upgrade, or expand the utility infrastructure to meet University requirements;

• provide recommendations for modification or upgrade of energy systems within

existing campus facilities and define comprehensive design guidelines to be

followed for projects that will renovate existing or new facilities on campus;

• establish guidelines for existing and new facilities that will optimize the efficiency

of building space utilization, with full consideration of occupant needs for teaching,

research, business functions, data storage and retrieval, and various University

auxiliary functions such as dining facilities and residence halls;

• provide recommendations to ensure Texas A&M is able to meet needs for reliable

and economic energy production and distribution of all utility commodities

provided to campus;

• reduce energy consumption and optimize the use of energy in the campus buildings;

• minimize energy losses in utility production and distribution systems;

• optimize overall utility plant and facility energy use efficiency;

• provide energy efficiency guidelines for new construction, procurement,

information technology, and building operation;

• reduce carbon dioxide emissions through the above efficiency gains, the use of

technology such as combined heat and power and evaluate cost-effective ways to

increase the use of renewable energy;

26

• provide incremental capacity for campus growth from reductions in demand created

by energy efficiency improvements and conservation;

• establish recommended energy efficiency design guidelines and standards for new

building construction on campus compared to the most recent ASHRAE and LEED

standards;

• position Texas A&M as a model of sustainable energy use and management with

full consideration and use of life-cycle economics;

• Identify and recommend implementation of technology improvements and upgrades

in the areas of utility and energy production, distribution, storage, metering,

automation, optimization, use and reporting to support the development of a smart

energy campus that continuously monitors and adjusts energy use to ensure overall

needs are met in the most reliable, efficient and cost-effective manner. Consider

and include, as appropriate, recommendations to support technology including plug-

in vehicles, use of direct current power supply for data centers, smart meters,

renewable energy generation, design standards for energy efficient equipment and

lighting, and energy management automation to monitor, integrate and optimize the

use of energy.

Historic and Projected Purchased Utility

Cost and Consumption

Texas A&M University has an outstanding record of accomplishment in recent years in

the area of energy consumption reduction and efficiency improvement. The campus has

over 21.5 million gross square feet (GSF) of building space and consumes 5.2 trillion

Btu‟s of energy annually - providing electricity, cooling, heating and other utilities in

support of the University‟s educational and research mission. Over the last eight years

(FY02 – FY10), $106 million has been cost avoided at the University through an active

energy management and efficiency improvement program (compared to the FY02

baseline). UEM manages the campus energy program with ongoing support from the

Energy Systems Laboratory (ESL) and Facilities Services. This combined expertise in

the area of energy and operational efficiency has resulted in a 35% overall reduction in

energy consumption per GSF on campus, from 364 mBtu/GSF in FY02 to 239

mBtu/GSF in FY10. This is an incredible accomplishment that has been nationally

recognized, with operational efficiency improvements and capital upgrades in the four

utility plants serving campus creating the most significant results.

Since the 1893, the University has generated a significant portion of the electrical power

and all thermal (cooling and heating) requirements for campus. Over the last five years,

29,000 tons of high efficiency cooling capacity has been installed in four campus utility

plants to meet new demand and replace older less efficient chillers. Texas A&M now has

over 50,000 tons of central cooling capacity, which is enough to cool 10,000 large homes.

The power and steam generation equipment in the Central Utility Plant (CUP) is in

progress of being upgraded to provide new higher efficiency power and steam generation

capacity by 2011. The CHP project will include the installation of a modern, high-

efficiency gas turbine generator and steam turbine generator with 45 megawatts (MW) of

electrical power capacity. A heat recovery steam generator (HRSG) will also be installed

with 210,000 lb/hr of steam generation capacity. These upgrades, together with other

electrical and steam system improvements, will further enhance the ability of Texas

A&M to provide clean, reliable, efficient energy to campus – making Texas A&M truly

world class in terms of utility plant reliability and efficiency. In addition to improved

efficiency and financial benefits, reduced energy consumption also results in lower Green

House Gas (GHG) emissions, helping to create a more sustainable environment.

While operating and optimizing campus utility production and distribution systems, UEM

manages energy systems in the buildings with a mission of meeting customer needs in the

most efficient manner possible. UEM manages an extensive utility metering program, a

sophisticated building automation/control system, lighting efficiency improvements, and

building energy system retro-commissioning.

Efficiency improvements in the buildings have been positive, but less dramatic than

improvements in the utility plants – with a six percent reduction in energy consumption

31

per GSF from FY02 through FY10. A six percent improvement in campus building

energy efficiency is positive, but there is still excellent potential for additional energy

conservation and efficiency improvement. The Energy Stewardship Program at Texas

A&M is placing energy stewards in campus buildings to work actively with building

occupants - educating, raising awareness and implementing initiatives to reduce energy

consumption. Providing leadership and continuing to make progress in the area of energy

conservation and efficiency, together with active environmental stewardship, enhances

the image of Texas A&M and supports the teaching and research mission.

On September 8, 2006, Texas A&M received a certificate from the Texas Comptroller of

Public Accounts, State Energy Conservation Office, recognizing the University for

achieving excellent results to improve energy efficiency and air quality in the State of

Texas. Texas A&M was only one of three Universities in the State to receive this

acknowledgment.

On August 14, 2007, the Association of Energy Engineers recognized Texas A&M

Utilities & Energy Management with the 2007 AEE Region IV Corporate Energy

Management Award. The award was presented in Atlanta, Georgia the day prior to the

opening of the World Energy Engineering Congress. The award is in recognition of

Texas A&M achieving excellent results in improving campus energy efficiency and

energy conservation.

On August 30, 2007, the Energy Systems Laboratory recognized Texas A&M Utilities &

Energy Management with the Mega-Energy Saver Award. The award is in recognition

for Texas A&M reducing utility costs with “green” improvements.

Savings Monitoring and Evaluation Plan

The university started installing revenue-quality utility meters in 2002 and by

August 2009, the goal of becoming fully metered in buildings larger than 5,000 GSF was

realized. Today, Texas A&M operates 1,400 utility meters in over 400 buildings,

allowing accurate billing and verification of energy efficiency improvements. The meters

measure consumption of electricity, chilled water, heating hot water, domestic cold

water, domestic hot water, and steam. The data is used to:

Troubleshoot problems in the buildings and measure their energy efficiency

Produce accurate cost estimates for budgeting purposes

Generate monthly customer statements, which raise awareness among campus

customers and demonstrate the results of conservation efforts

Generate accurate monthly billing and allow for accurate and timely cost recovery

An integral part of the metering project is the SQL database that was developed to

organize and store all meter consumption information. The electronic meters are polled

via the campus Ethernet, stored in the application software, and then exported into the

main SQL database. Manually read meters have their data entered via web-based

interface developed internally by UEM.

All metered data is organized by customer, and by building, and plotted to show a

consumption profile for that utility. These profiles are reviewed for reasonableness and

any anomalies recorded and sent to field technicians for sensor verification.

Measurement of utility consumption is recorded to determine conservation results

achieved through energy consumption reduction initiatives such as HVAC system

modification, scheduling, lighting retrofits, etc.

Utility invoices are created and posted monthly for auxiliaries and agencies, which are

directly billed for their utility consumption. Educational and General (E&G) entities are

not directly billed for consumption but monthly statements will be generated starting with

September 2010 to raise awareness for both energy consumption and cost.

With the combination of meters that measure the consumption of electricity, chilled

water, heating hot water, steam, domestic cold water, and domestic hot water, together

with other areas such as athletic and agriculture fields, the University will be prepared to

record and closely manage all utility consumption.

The ability to accurately see where, and how much, energy is being used is the first step

in recognizing where waste and inefficiency exist. The next step will be to utilize this

information to implement measures to eliminate waste, improve efficiencies, and promote

energy and water conservation.

Project Implementation Update

Sept 2010

Retro-Commissioning Existing Facilities

UEM leads the program with support from Facilities Maintenance and ESL, with a goal

of improving HVAC system effectiveness and efficiency through commissioning of

energy systems in existing facilities. Close to 50 buildings on campus have been retro-

commissioned since FY06.

Utility Plant Performance Optimization Program (POP)

In 2011, UEM will be implementing a Utility Plant Performance Optimization Program

that will provide real-time monitoring capabilities and enable operational staff to make

better decisions regarding which equipment to operate based on a number of equipment

and operational variables. The program will also provide modeling capabilities to model

the efficiency of different plant operating scenarios.

Energy Consumption Reduction Measures

The University has engaged in a more aggressive campaign to upgrade building

automation systems and increase lighting efficiency across campus using a performance

contract and a low interest loan made available through SECO. The overall program

consists of two loans – one for $10 million and second for $5.1 million. The details of

the project are as follows:

Connecting occupancy sensors (already present or to be installed as part of the

lighting retrofit) to the TECs (Terminal Equipment Controllers) in order to reset space

temperature and airflow setpoints based on occupancy.

In non-lab areas (offices, classrooms, conference rooms, etc.), the room temperature

setpoints will be:

- Daytime and nightime occupied: 70 °F for heating and 75 °F for cooling,

- Daytime unoccupied: 65 °F for heating and 80 °F for cooling,

- Nighttime unoccupied: 60 °F for heating and 85 °F for cooling

When the occupancy sensor indicates that the space is unoccupied, the minimum

airflow for VAV boxes will be reset to zero (no flow), where permissible.

In lab areas served by 100% outside air units, the ventilation setpoint will be reset

from 8 ACH to a minimum of 4 ACH (air changes per hour) only when the system is

in “night” mode and the occupancy sensor indicates that the room is unoccupied.

Temperature setpoints for lab areas will be:

- Daytime (regardless or occupancy): 70 °F for heating and 75 °F for cooling,

- Nighttime occupied: 70 °F for heating and 75 °F for cooling,

- Nighttime unoccupied: 60 °F for heating and 85 °F for cooling

- Laboratories with specific temperature requirements will be programmed to

maintain these accordingly.

Converting control systems at the AHU and zone levels from pneumatic to direct

digital control (DDC).

38

Implementing heating/cooling and day/night temperature setpoints with DDC in

zones that were previously controlled pneumatically with a single setpoint.

Optimizing the discharge air temperature and static pressure reset programming to

minimize unnecessary reheating and fan power.

Tying exhaust fans to the BAS in order to schedule them off at night.

Installing VFDs on constant-speed AHU fans to reduce fan motor energy use and

improve dehumidification capability.

Installing VFDs on constant-speed pumps and programming differential pressure

setpoint schedules.

Re-commissioning heat recovery systems previously removed from service.

This scope of work will be implemented in 19 teaching and research facilities that total

over 3.3 million GSF. In addition to the BAS projects, the lighting in all five campus

parking garages will be retrofitted to a higher efficiency fixture and many lighting

upgrades will be performed in same buildings receiving BAS upgrades.

Estimated Cost: $15.1 million

Estimated Completion: December 2011

SUP1 Chilled Water Improvements (necessary to meet reliability requirements)

The three steam driven centrifugal chillers in SUP1 were replaced with new electric

centrifugal machines to enable the machines to operate without steam service to the plant.

It also provides excellent operational savings because the new units will replace steam

driven chillers with very poor efficiencies. In addition to converting/replacing the steam

driven centrifugal chillers, steam service to West Campus should be discontinued, the

absorption chillers should be removed, and additional chiller capacity should be added to

help the plant meet N+1 redundancy goals. When the 6000 total tons of steam driven

chilling is removed there will be cooling tower capacity sufficient to support the

installation of 8400 tons of electric centrifugal chillers. This project should be undertaken

as soon as possible, as this will ensure sufficient capacity to meet load growth as well as

bring immediate energy and cost savings to the campus.

This project has been completed.

Annual estimated avoided cost: $1,250,000

Building Thermal Loop Optimization

Optimizing low system differential temperatures (DT‟s) presents an ongoing challenge.

Effective and efficient delivery of cooling and heating energy to all the buildings is

another important responsibility. Optimizing loop pressures throughout the system

requires consistent and comprehensive management of building controls, plant and loop

operation, and central thermal system development planning.

This is another energy conservation measure that has been successful and will be more

fully evaluated in the Utilities & Energy Management Master Plan.

39

Combined Heat & Power (CHP) Upgrade in the CUP

Since the 1893, Texas A&M has generated a significant portion of the electrical power

and all thermal (cooling and heating) requirements for campus. Over the last five years,

29,000 tons of high efficiency cooling capacity has been installed in four campus utility

plants to meet new demand and replace older less efficient chillers. Texas A&M now has

over 50,000 tons of central cooling capacity, which is enough to cool 10,000 large homes.

The power generation equipment in the Central Utility Plant (CUP) had also reached the

end of its useful life and a new Combined Heat and Power (CHP) project is in progress to

provide new higher efficiency power and steam generation capacity by 2011. The CHP

project will include the installation of a modern, high-efficiency gas turbine generator

and steam turbine generator with 45 megawatts (MW) of electrical power capacity. A

heat recovery steam generator (HRSG) will also be installed with 210,000 lb/hr of steam

generation capacity. These upgrades, together with other electrical and steam system

improvements, will further enhance the ability of Texas A&M to provide clean, reliable,

efficient energy to campus – making Texas A&M truly world class in terms of utility

plant reliability and efficiency. In addition to financial benefits, reduced energy

consumption also results in lower Green House Gas (GHG) emissions, helping to create a

more sustainable environment.

Estimated Cost: $73.25 million

Estimated Completion: December 2011

Estimated FY12 Cost Avoidance (before debt service): $5.7 million

Estimated FY12 Cost Avoidance (after debt service): $1.0 million

Energy Stewardship Program

The Energy Stewardship Program (ESP) was started in July 2009 as a pilot that included

(40) buildings for a total of 5.8 million GSF. ESP is designed to reduce energy

consumption and cost of operation in campus buildings by improving energy

conservation and efficiency while improving environmental conditions. When fully

implemented, ESP will assign an Energy Steward (ES) to every building with significant

energy consumption. The ES will become familiar with occupant needs in their assigned

buildings and perform a key role to inform and educate occupants on the most efficient

and cost‐effective use of energy. The ES will also develop an understanding of HVAC

and control systems, lighting, water, and other energy requirements in the buildings and

act as a liaison with technical support staff who will work with them to ensure occupant

needs are met in the most cost‐effective manner. In addition to reducing consumption

through improved conservation and efficiency, ESP will focus on ensuring proper air

quality and comfort standards are consistently met.

With a goal of improving service while educating, informing and enrolling building

occupants, the ES will have access to energy consumption and cost data – overall and per

gross square foot ‐and use this data to educate themselves and others. The ES will meet

with building proctors and/or facility managers, and occupants to continuously raise

awareness and improve operating efficiency. They will also meet with department

40

managers and representatives to ensure thorough understanding of occupant energy

requirements and schedules. The ES will tour assigned buildings observing all aspects of

energy consumption, room temperature, humidity, and lighting. Unnecessary

consumption will be identified and steps taken to improve operating efficiency while

educating occupants and requesting support to encourage every occupant to become a

steward for efficient energy use. Temperature, humidity and air flow issues that need

correction will be documented, along with recommended solutions, so effective

corrective measures can be implemented. Mechanical rooms and energy systems will be

inspected routinely to ensure HVAC systems, VFD‟s and controls are operating properly.

Energy Stewards will spot check buildings during and after normal occupant working

hours and weekends to ensure conservation measures are being implemented and

maintained as expected and make note of wasteful energy use, along with required

solutions.

The ES continually ask the following questions in each of their assigned buildings:

Are occupants comfortable and are departmental requirements being met?

Are temperature, humidity and air flow standards being achieved and not exceeded?

Are space heaters or other energy wasting devices being used? If so, why?

Are HVAC systems and lighting being secured after regular business hours?

Are HVAC systems, pumps and controls operating as intended? Are any being

bypassed?

Are lights and equipment being turned off when not needed? If not, why not?

Is there any water (DCW, DHW, CHW, HHW) being wasted or improperly used?

Are there any other improvements that will conserve energy or improve efficiency?

Once a week, all ESs meet with the ESP Management Team (EMT) to review and report

progress, request needed assistance or resources, and get appropriate approval to proceed

with specific initiatives. Energy Stewards will present people and process challenges,

with recommended solutions, to the BMT so priorities can be established, strategic

decisions can be made, and necessary approvals or support can be obtained.

In addition, the ESs will be supported by a ESP Technical Team (ETT), comprised of

members from UEM Energy Services (UES), UEM Analytical Services (UAS), Energy

Systems Laboratory (ESL), and Facilities Maintenance (FM). A weekly ETT meeting

will be held to review energy consumption and cost profiles, discuss accomplishments

and review technical challenges, and identify solutions or follow‐up action required.

Energy Stewards will review specific energy consumption reduction measures they have

identified in buildings with the BTT to determine the best technical solutions and course

of action.

ESP is an ongoing process of improvement to identify and eliminate waste, inform and

educate building occupants, and enroll ALL building occupants in the process of

conserving energy and improving energy efficiency. As first priority, the ES will work

with occupants, EMT and ETT to identify and eliminate energy use that is obviously

wasteful and improve building operational efficiency without investment of capital or

major maintenance. While raising awareness and implementing priority one items, the

41

second priority of the program will be to identify and implement space use efficiency

improvements that can be made without significant modification, capital investment or

major maintenance. As a third priority, with ongoing support from the EMT and ETT,

opportunities will be identified, working with various departments and building

occupants, that will accomplish greater operational efficiency through improved space

usage, consolidation of like uses, capital upgrades, improved mechanical/electrical

systems and controls. Each of the priority three opportunities will require thorough

discussion, review, justification, management approval and funding to implement.

If made a high priority by Texas A&M administration and academic department

management, ESP has the potential to cost avoid millions of dollars annually through

reduced purchased energy consumption, significantly improve the environment, and

provide world class support for the Texas A&M mission of teaching and research. This

accomplishment and the example it demonstrates will provide tremendous positive

benefit to the many students, faculty, staff, alumni and stakeholders of Texas A&M. This

benefit will extend far beyond Texas A&M and the current generation of students, faculty

and staff. Our accomplishment and leadership in the field of energy conservation and

efficiency will provide an example for institutions and individuals throughout the country

and around the world.

The pilot program was conducted in over 40 buildings totaling over 5.8 million GSF.

Energy Systems Lab (ESL) estimates the cost avoidance of the program in excess of

$350k annually. Based upon the results, the program was expanding in October 2010 to

include a total of (55) buildings and 7.3 million GSF.

HVAC Scheduling

HVAC scheduling is simply identifying those buildings that can be shut down or set back

during unoccupied periods. This means that if a building is occupied from 8:00am to

5:00pm, Monday through Friday then be sure to turn off the HVAC or set it back during

unoccupied periods. UEM has developed a way to measure the effectiveness of the

program by establishing the HVAC run time index. The HVAC run time index is simply

the number of hours in a given period that the HVAC system is running, divided by the

total number of hours in that period. For example, if the HVAC is scheduled to run from

6:00am to 6:00pm Monday through Friday and be setback or turned off during other

periods, the HVAC run time index would be about 36%. As a point of reference, our

campus HVAC run time index is currently about 79% for those buildings that we can

schedule and we do have a building that is operating at about 45%.

A variation to HVAC scheduling is Holiday HVAC scheduling. Texas A&M has had a

holiday HVAC scheduling program in place since the fall of 2005 which is focused on

the holiday breaks in November, December and March. These months are periods where

the students, faculty and staff are gone from campus for longer periods than normal.

Prior to the 2005 holiday season, there was recognition that most of the 21.5 million GSF

would operate as normal unless something was changed. The team very quickly put

together a plan and moved forward with turning off equipment or setting it back where

shutting it off is not practical or does not meet the needs of the occupants.

42

Through this past holiday period, we have avoided of $1.5 million in direct energy cost.

Cost avoidances is measured in direct cost not total cost because only purchased energy

cost is being reduced. With a carbon foot print of 506,000 MTeCO2, the savings to date

represent 5% of the annual total.

More remains to be done with this program by consolidating server rooms or moving

them to a centralized data center so that air handlers that server entire floors of a building

do not have to run 24/7 to meet the requirements of the server located in a closet.

Water Conservation Plan

44

Water Conservation Plan

Texas A&M has an outstanding record of accomplishment in recent years in the area of

water conservation. Over the past eighteen years, Texas A&M has implemented a number

of significant water conservation initiatives and water system improvements to ensure

University water needs are met in the most efficient and cost-effective manner. These

conservation efforts and operational improvements have resulted in huge reductions in

the amount of water required to operate and maintain the 21.5 million Gross Square Foot

(GSF) campus.

Texas A&M water consumption has been reduced by over 50 percent since the early

1990‟s and by almost one third since 2000. FY2010 water consumption of just over 1.5

billion gallons has set a record low. This reduction was accomplished while serving a

campus that has experienced a growth of 43% in square footage served (from 15 million

GSF in 1991 to 21.5 million GSF in 2010). This 50% decrease in overall water

consumption with a 43% increase in campus square footage represents a 65% reduction

in consumption per GSF!! This result has been accomplished by implementing 1)

improved utility plant operation and water treatment to reduce water consumption

required to provide electrical power, cooling and heating for campus, 2) improved

automation and management of campus irrigation systems, 3) improved standards for

building plumbing fixtures, 4) LEED certification standards for major new buildings, 5)

improved education and promotion to raise awareness of energy and water conservation,

and 6) separation of non-potable water systems from the campus municipal water system.

The domestic water system on the Texas A&M campus is operated and maintained by

Utilities & Energy Management and is rated as a Superior water system by Texas

Commission on Environmental Quality (TCEQ). Water rates at Texas A&M are also

some of the lowest in the State of Texas at a cost to customers of $1.57 per thousand

gallons. The UEM mission to ensure high reliability of utility services and environmental

stewardship, while reducing utility rates and consumption, supports the Texas A&M

mission of excellence in teaching and research.

Long Range Utility Procurement Plan

Energy Procurement Strategic Plan

Since FY06, Texas A&M has employed the consulting firm Fulcrum Power Services for

the purchase of electricity and natural gas. Texas A&M currently purchases a

combination of natural gas futures and options contracts via the NYMEX to hedge future

energy costs. Texas A&M has hedged the energy requirements for FY11 at 95%, FY12

at 60% and FY13 at 25%. All energy consumption is currently being hedged using

financial hedges in natural gas, which are then converted prior to the start of each month

into physical natural gas or electricity.

Texas A&M is currently upgrading its own site power generation capability through the

CHP project previously mentioned. To ensure that the natural gas delivered to the

Central Utility Plant is of sufficient pressure, Texas A&M entered into a transportation

agreement with Atmos to install a pipeline and deliver 600 psi gas to the facility. Texas

A&M is also seeking competitive bids for the supply of natural gas and expects that a

new purchase agreement will be in effect by January 2011.

Section Fourteen

Fleet Fuel Management Plan (vehicles)

53

Fleet Fuel Management Plan

The following procedures have been and still are in place:

Reduced bus routes – focus on efficiencies

Reduced fleet vehicles – retiring older, less efficient vehicles

Photocell lighting used on exterior of all garages

Replaced lights in automotive shop with more efficient fixtures

Photocell lighting used at the fuel island

Fuel island offers biodiesel (B20) and have dedicated one 12,000 gallon

underground storage tank for biodiesel storage

Preventive Maintenance schedules have increased to 3 per year instead of twice a

year improving fuel efficiency.

Signs have been posted at the fuel center with helpful tips encouraging customers

to conserve fuel

Conservation tips have been posted on our website

A brochure has been produced regarding fuel conservation and is included with

each fleet rental agreement

We continue to communicate our efforts with Communication Representative

from Energy Conservation Committee and offer assistance where needed with

University-wide conservation efforts

Bid proposal for biodiesel has been reviewed by Purchasing. Biofuels vendor

Brenco Marketing has been selected.

Purchased 4 Ford Escape Hybrids

Purchased 6 Chevy Malibu Hybrids

The following procedures and communication efforts are proposed for immediate action:

Continue to replace lighting with more efficient fixtures at the heavy equipment

shop

Continue to investigate use of hybrid vehicles in the fleet

Research the effects of using B20 during the winter months

Research fuel additives to reduce gelling during the winter months

Continue to use B20 biodiesel in all Transit buses

Utilizing biodiesel in other university vehicles

Aggressively researching electric vehicles such as the E-ride (http://www.e-

ride.com/), Miles (http://www.milesev.com/) and Zenn

(http://www.zenncars.com/).

Week long test of three electric vehicles (two E-ride models and one Miles truck).

During the week long test, departments were allowed to use them in real work

scenarios to test their feasibility.
