Energy Initiatives of MCAS Beaufort Neil Tisdale
June 13, 2012
Major Energy Projects Executed
• Base Wide EMCS – Saving 34,507 MBTU/Year
• Phase I ESPC – Saving 55,474 MBTU/Year
– Ground-source Heat Pump (GHP) in 30 Buildings
– 75% of HTHW Distribution System Abandoned
– Lighting Controls
– Barracks tied into main chiller plant
– Merged Controls with EMCS
• Phase II ESPC – Saving 18,230 MBTU/Year
– GHP in 5 Buildings
– 1.5MW / 9MBTU Micro Turbine Co-Generation Plant
– 750-Ton Variable Flow Chilled Water Plant
– Hangar and High Bay Area High-Intensity Fluorescent Lighting
Occupancy Override
•Allows for heating/cooling when the
building is scheduled off.
•Time is added per push.
•Up to 3 pushes can be used to
accumulate time.
•Time per push is generally 90 minutes
but can be programmed for higher values
Occupancy Indicator Light •Red indicates that the space is under
normal temperature control
•Summer set point is generally 78F.
•Winter set point is generally 68F
Set Point Adjustment •Allows adjustment to the space
temperature plus/minus 3 degrees F.
ESPC Phase II
• Awarded by September 2003
• 10 additional buildings
• CHP replaced by Co-Gen plant.
• 6 man-years of labor savings.
• 10,000 MBTU of energy savings projected.
• Central Chiller plant moved and upgraded
• Hangar and high bay lighting replaced
• 5 buildings on Geothermal
• Controls will be integrated with base EMCS

ESPC Phase III
• 25 watt T-8’s and CFL’s in 45 buildings.
• Low flow shower heads, sink aerators, and flush valves in 99 buildings.
• DDC system in 12 buildings.
• 7 chillers replaced.
• Ice storage chiller at 431 and on geothermal at 1108.
• Solar hot water at 554 Officer’s Club.
• 4.2% energy reduction.
• 9% water consumption reduction.
