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
