  1. JBSA Energy JBSA Energy team

  2. JBSA Energy Team • Randolph, • Lackland • Fort Sam Houston

  3. Goals • Reduce energy use by 3% per year • Reduce potable water usage intensity by 2% per year • Reduce fuel use by 3% per year • Increase alternative fuels use by 2% per year • Install required electric, gas and water meters; AETC contract(s) • Renewable Energy vs goal not required if not feasible • Audits - accomplished through AETC contract(s) • Energy Security • Enhance base energy infrastructure and facilities • Develop innovative ways to operate & maintain facilities to reduce utility costs • JBSA-wide Awareness campaign

  4. Initiatives Requirements • Building Metering and Control – Methodology to deliver higher energy performance - Last year’s Workshop • Water Conservation and Efficiency – Development and demonstration of technologies • Energy Conservation and Efficiency – Technologies that support sustainable building design and operations • Alternative Energy Sources – Alternative energy from centralized power generation sources • Renewable Energy Generation – Developing and demonstrating renewable technologies • Audit/Commissioning technology – Data collection/modeling for energy sustainability • Innovation Center – share tech info – other people’s money • Energy Efficient Fuels/Vehicles

  5. Energy Intensity vs Goal • Consumption • JBSA MBTU per sqft % vs goal

  6. Utility Cost • Utilities Cost ($000) FY11 & 12

  7. Goal Analysis 000 Kwh

  8. JBSA Energy News • From last year’s workshop • EMCS Project Progress • Lackland • Fort Sam Houston • Randolph*

  9. JBSA Initiatives • Traditional Focus Funding leaving us short • Partnerships (DTI) – Innovation Center • Public Awareness • Commissioning/re-commissioning • High Performance Specification – beyond LEED • ESPCs/ECIP • New Technology Opportunities • ESTCPs; Plasma lighting, facility system, HVAC condensate • AFRL- JBSA facility energy technology; Concentrated Solar • Utility provider • Joint Awareness Campaign • LED Lighting FSH • Home Network • Area-wide Contract ECMs/UESC

  10. Goal Analysis 000 Kwh

  11. Questions?

  12. JBSA/Randolph AFB Virtual Chilled Water Plant

  13. Initial Concept • Central Chiller Plant B991 with TES • ESPC Project to construct chiller plant, Thermal Energy Storage (TES), and interconnect multiple facilities • Removed inefficient building air cooled chillers • Solid results

  14. Replication • B395, B738, and B496 had large centrifugal chiller plants with excess capacity • Interconnect surrounding facilities • Remove inefficient individual air cooled chillers

  15. Plant Interconnection • Excess capacity at B991, B738, B395, and B496. • Interconnect plants • Connect additional buildings on east and south side of installation • Removal of more inefficient air cooled chillers B496 Bldg Bldg Bldg

  16. Replace Plant • B496 AFPC plant reconstructed to serve renovated facility along with additional buildings on west side of installation • Removal of inefficient air cooled chillers, replacement of inefficient centrifugal chillers • Excess capacity available

  17. EMCS Status • Complete FY12 EMCS project to add building BTU metering and central plant optimization • Connect other buildings to virtual plant

  18. Final Randolph Chilled Water Loop Vision • Interconnect B496 to B395 and B991 plants • Install Thermal Energy Storage (TES) at B496 and B395 plants • Perform retro-commissioning of all buildings served by district plants to maximize efficiency and energy savings

  19. JBSA/Randolph AFB End Status and Project Highlights
