2. Key Energy Directives • EISA 07 • Reduce energy use in federal buildings 3% per year relative to the 2003 baseline ending in a 30% reduction in energy intensity by FY 2015 • EO 13423 • Reduce water consumption intensity, relative to the 2007 baseline by 2% annually through the end of FY 2015 • At least 7.5% of electricity from renewable sources beginning FY 2013 • NDAA 07 • 25% of all energy consumed will be supplied from renewable sources • EO 13514 • Reduce water consumption intensity 2% annually through FY 2020

3. FY09 Utility Cost - $16M

4. FSH Energy Updates • Reduce Energy Consumption • HVAC set-backs are enforced, Install occupancy sensors, etc • DPW Reduce Fleet Dependency • Turned in 4 vehicles after a recent review • Only 18 vehicles on recurring dispatch plus 5 electric vehicles to help mitigate the shortfall • Reduce Water Consumption • Fort Sam Houston has a 0% potable water irrigation policy • Approximately 840 acre feet (273 million gallons) of reuse water is used for irrigation and some cooling towers • Creative solutions required to accomplish goals

5. Cool roof applications Solar daylighting and daylighting controls Solar PV - roof and ground mounted applications Solar Hot Water systems Increase thermal energy storage for existing solar hot water system Energy Projects

8. Based on current usage, FSH must offset 176 million gallons of potable water by 2020 121,360,600 KWh of electricity by 2015 MANDATORY BY 2013: 9,102,045 KWh (7.5%) must come from renewable sources or 4,551,023 KWh (3.75%) if produced on-site Options 3.75% = 3 MW System = 300,000SF = $21M ($14.6M post incentive cost) Bldg 1350 PV array is producing 174,000 KWh per year (0.14%) Additional $1,420,000 annually to purchase renewable energy credits RECs may not qualify in the future Renewable Energy Goals

9. Improving efficiency Recent example – recovered $2.6M from Camp Bullis Double charged on meter readings from the master meter and building meters. Without improving efficiency FSH will have to offset 121,360,600 KWh by 2015, to meet energy goals Solar PV System Size Required: 79.5 MW Area Required: 8 Million SF Estimated Cost for Government: $557 M Estimated Cost applying federal incentives: $390 M Achieving Goals

10. Efficiency Conduct regular PM, expand UMCS, install occupancy sensors, expand behavioral changes, reduce energy use for cooling and heating (1 degree = 3%) Insulation Maintain weatherization of windows and doors, exterior building insulation and cool roof applications Renewable Solar daylighting and daylighting controls Solar PV systems Solar car ports, ground mounted solar arrays, and solar roof applications Way Ahead
