3 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, 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, 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 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. 3

5 Section One Resource Efficiency Plan Certification Document 5

6 Resource Efficiency Plan Certification Document The resource Efficiency Plan Certification Document is a one-time certification that acknowledges the completion of the Resource Efficiency Plan (REP) required by 34 TAC (a), and assures that the recommendations contained in the REP will be implemented. The Resource Efficiency Plan certification document remains unchanged from December Please refer to the December report. 6

7 Section Two Utility Assessment Reports 7

8 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: 8

16 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. 16

19 Section Four Finance Strategy 19

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 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 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 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. 20

21 Section Five Utility Awareness Plan 21

22 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 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. 22

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 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. 23

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. 24

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; 25

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 plugin 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. 26

27 Section Six Asset Management Plan 27

28 Asset Management Plan The Asset Management Plan presents information on building gross square footage and departmental space data based on inventory information managed by the Texas A&M University Office of Facilities Coordination (FCOR). The Asset Management section has not changed for this update. Please refer back to the December 2005 plan. 28

29 Section Seven Historic Utility Use and Cost 29

30 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 The CHP project will include the installation of a modern, highefficiency 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 30

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.

34 Section Eight Savings Monitoring and Evaluation Plan 34

35 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. 35

36 Section Nine Project Implementation Update 36

37 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 retrocommissioned 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). 37

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 s (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. 38

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 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 39

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 40

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. 41

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. 42

43 Section Ten Water Conservation Plan 43

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 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. 44

45 Section Eleven Long Range Utility Procurement Plan 45

46 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
