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

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
