1 Energy Management Report November 2013

2 A. The extent to which the agency has met the percentage goal it established for reducing its usage of electricity, gasoline, and natural gas: Energy consumption per gross square foot has been reduced by 45% (364 mbtu per GSF to 205 mbtu per GSF) over an eleven year period from FY02 FY13. The goal in the 2005 Energy Conservation Plan was to achieve an EUI of 275 by FY10 which was achieved and surpassed. Total real energy consumption has decreased 25 percent over this same eleven year period, from 6.5 trillion Btu in FY02 to less than 4.8 trillion Btu in FY13, while the campus grew by over 28 percent, from 18.5 million GSF to 23.7 million GSF. Energy consumption reduction measures over this same ten year period (FY02 FY13) have generated over $162 million in avoided cost. Texas A&M University has provided exemplary leadership in the area of energy efficiency improvement and conservation with these accomplishments. (see attached charts). The most recent energy consumption data comparing FY11 at 5.26 trillion Btu to FY13 at 4.84 trillion Btu, reflects a real energy consumption reduction of almost 8 percent in the last two years alone, with much of this reduction resulting from the startup of a newly completed combined heat and power (CHP) plant. B. The steps the agency may take to increase the percentage goal for reducing its usage of electricity, gasoline, and natural gas: Texas A&M University has established and actively manages an Energy Action Plan (EAP) 2015 which targets further reduction of energy consumption per gross square foot over five years from FY10 through FY15. The goal of EAP 2015 is to reduce the overall campus Energy Use Index (EUI) from the FY10 baseline of 238 mbtu/gsf to 190 mbtu/ GSF by the end of FY15, or a reduction of 20% per GSF over 5 years. (see attached Energy Action Plan 2015 and EUI Chart ) In January 2012, Texas A&M completed a $15 million energy efficiency project with Siemens acting as the Energy Services Company (ESCO) that included consumption reduction measures in 18 buildings and 5 parking garages. These efficiency improvements in the facilities included lighting upgrades, building automations system retrofits, and HVAC system improvements. The first year (FY12) energy consumption reductions in the buildings far exceeded the guarantee for avoidance by 173% for electricity, 182% for chilled water and 145% for heating hot water. In September, 2013, the University has embarked on Phase 3 of the SECO loan projects and began implementation of an additional $4.1 million in HVAC and lighting improvements in 10 buildings with a total of 802,000 GSF. The Energy Stewardship program continues to pay dividends by closing the gap between organizational needs and operational efficiencies. The University currently has 6 full time energy TAMU Energy Management Report November of 3

3 Stewards, each assigned an average of 2.6 million GSF. The stewards proved invaluable as the recent $15 million SECO loan project was implemented by facilitating the construction process and enabling additional cost avoidances to be achieved. Instead of the construction project simply making modifications and walking away from the project, the stewards identified additional opportunities through scheduling and setbacks that allowed the project to exceed expectations by more than 50%. An updated Utilities & Energy Services Capital Plan was completed in 2012, which documented and justified $46 million in production and major infrastructure improvements that are required over the next five years. These projects were placed on the University Capital Plan for the period of FY13 FY17. The Texas A&M Board of Regents has approved design and construction on the first phase of capital improvements and has approved design on the second phase. The initial FY13 utility production upgrade project has a $12 million budget and will increase capacity for a growing campus, replace aging equipment, and generate $1.25 million annually in cost avoidance through improved operating efficiency. The FY14 project has a $20 million budget and will continue upgrading campus production facilities to meet the growing demands of the campus while cost avoiding over $1 million annually. The scope of capital upgrades approved for construction include: o Replacement of Chiller SUP1 o Replacement of Chiller CUP o Addition of Heat Recovery SUP2 o CUP / SUP1 Cooling Tower Upgrades o Chilled Water Production Optimization o Installation of Chiller SUP2 The scope of capital upgrades that are in design include: o Installation of Thermal Energy Storage o Replacement of Chiller CUP o Replacement of Chillers 301, 302, & SUP3 o Cooling Tower SUP3 o Addition of a Heating Hot Water SUP1 The retro commissioning program on the campus continues to prove successful by identifying and implementing energy conservation opportunities as well as identifying system wide improvements needed to the campus HVAC and building automation systems (BAS). C. Any additional ideas the agency has for reducing energy expenditures relating to facilities: The University has established an energy efficiency design guideline that targets new facilities to demonstrate the ability exceed ASHRAE by 14% for new construction and 11% for renovation. An associated energy impact review, coupled with life cycle cost modeling will enable the University to make the best long term decisions regarding operational efficiency of campus facilities.

4 In addition to identifying opportunities to improve operating efficiency of building HVAC, BAS, and lighting systems, UES is evaluating opportunities to more precisely regulate the face velocity associated with over 1,000 fume hoods located on the Texas A&M University campus to ensure safe operation with improved energy efficiency. D. Any additional ideas the agency has to minimize fuel usage in all vehicles and equipment used by the agency. The following procedures have been and still are in place: o Reduced bus routes focus on efficiencies o Reduced fleet vehicles retiring older, less efficient vehicles o Photocell lighting used on exterior of all garages o Replaced lights in automotive shop with more efficient fixtures o Photocell lighting used at the fuel island o Fuel island offers biodiesel (B20) and have dedicated one 12,000 gallon underground storage tank for biodiesel storage o Continue to use B20 biodiesel in all Transit buses o Preventive Maintenance schedules have increased to 3 per year instead of twice a year improving fuel efficiency o Signs have been posted at the fuel center with helpful tips encouraging customers to conserve fuel o Conservation tips have been posted on our website o A brochure has been produced regarding fuel conservation o We continue to communicate our efforts with Communication Representative from EAP 2015 Advisory Committee and offer assistance where needed with University wide conservation efforts o Purchased 12 Hybrid vehicles. o Purchased one electric vehicle, 2012 Chevrolet Volt. o Replaced lighting in heavy equipment shop with more efficient fixtures. o Updated brochure regarding fuel conservation and signage at the fuel island The following procedures and communication efforts are proposed for immediate action: o Continue to investigate use of hybrid and electric vehicles in the fleet o Utilizing biodiesel in other university vehicles University Fleet Fuel Consumption (provided by Transportation Services) University Fleet FY2004 FY2005 FY2006 FY2007 FY2008 FY2009 FY2010 FY2011 FY2012 FY2013 Reduction from FY04 Fuel Type Units % Actual Diesel Gallons 979, , , , , , , , , ,520 B20 Gallons 22, , , , , , ,203 Total Diesel 979, , , , , , , , , ,723 48% (470,015) Gasoline Gallons 812, , , , , , , , , ,210 68% (551,871) Propane MMBTU % (845) TAMU Energy Management Report November of 3

5 Energy Action Plan 2015 Purpose: In support of the Texas A&M University Vision 2020: Creating a Culture of Excellence and Action 2015: Education First Strategic Plan, the Energy Action Plan (EAP) 2015 has been established to continue improving the efficiency and effectiveness of mission-critical utilities and energy services.
