Energy Study
 

2RW completed a phase III detailed energy study for the United States Marine Corps (USMC), in support of a guaranteed energy savings project. Marine Corps Air Station (MCAS) Beaufort hosts all active duty USMC F/A-18 air operations on the East Coast, assigned to Marine Aircraft Group (MAG-31). The mission of the Marine Corps Air Station Beaufort is to provide support as an operational base for MAG-31, and the support units.

The mission of the MAG-31 is to conduct anti-air-warfare and offensive air support operations in support of Fleet Marine Forces from advanced bases, expeditionary airfields, or aircraft carriers and conduct such other air operations as may be directed. The population of the on-base “city” includes nearly 4,000 active-duty service members and more than 700 civilian workers. There are also two US Navy F/A-18 squadrons assigned to the installation.

MCAS Beaufort is located four miles from downtown Beaufort, South Carolina. Managing more than 12,000 acres, the air station includes the Laurel Bay military family housing just outside the main gate and Townsend Bombing Range about 130 miles away in McIntosh County, Georgia. There are two runways at the air station in Beaufort.  One is 12,000 feet long; the other is 8,000 feet. Another 8,000-foot runway could be added easily, and there is enough room for expansion of all of the facilities. MCAS Beaufort is an alternative Space Shuttle landing site for NASA.

The detailed energy study included approximately 750,000 square feet in 28 different facilities.  Energy Management and Control Systems (EMCS) Design Services were provided for ten separate facilities totaling 335,000 square feet. The focus was on replacing aging air cooled chiller plants with new high efficiency chiller, re-commissioning energy storage (ice tank) systems, and expansion of the EMCS.

The analysis was conducted with Trane TRACE 700 whole building simulation software. A baseline simulation was created and calibrated using metered and logged data according to the Federal Energy Management Program’s (FEMP) M&V Guidelines: Measurement and Verification for Federal Energy Projects. This simulation reflected current arsenal operation and energy consumption. The baseline simulation was then altered to incorporate recommended energy conservation measures (ECMs) to determine the energy savings.

 

 

Results

The detailed energy analysis identified, quantified, and provided preliminary design (in support of construction contractor pricing) for new chiller plants, and connecting a new water-to-water geothermal heat pump system to an existing loop field. The annual savings associated with these measures were estimated to exceed $400,000.
