Langley Air Force Base (Langley, VA)

United States Air Force

In FY 2004 the Air Combat Command's (ACC) Civil Engineer Energy Management Team used a utility energy services contract with Dominion Virginia Power to convert the outdated heating, air conditioning, and ventilation systems at eight ACC Headquarters facilities to water source heat pump technology—the first large commercial application of water source heat pumps for the Air Force. The Team replaced 2,700 tons of inefficient chillers with 1,200 tons of efficient heat pumps, providing heating and cooling to 516,000 square-feet of Base facilities. Additionally, the project installed more than 10,000 high-efficiency lighting fixtures and replaced water conservation fixtures on all campus plumbing. Together, these measures save 57.8 billion Btu and 3.8 million gallons of water annually. More importantly, marginal office spaces have become comfortable, productive work environments for Air Force employees.
