Utility Energy Service Contract Case Studies

The following case studies showcase utility energy service contract (UESC) projects conducted by Federal agencies.

• Coast Guard Multi-Site UESC Project: Twelve-site project with 21 energy-conservation measures reduced electricity consumption by 19.1%, water consumption by 64.2%, and natural gas consumption by 21.1%.

• Video Case Study: National Institute of Health: Saved at least $5 million in annual energy costs at its main campus in Bethesda, Maryland, through energy conservation measures.

• General Services Administration Ted Weiss Federal Building: Multiple energy conservation measures and utility services saved $256,000 in annual energy costs and 64,872 Btu per gross square foot.

• Patrick Air Force Base: Base-wide energy program implemented to exceed energy intensity reduction goals and requirements.

• U.S. Department of Energy Fermi National Accelerator Laboratory: Energy efficiency upgrades to a centralized cooling system save $900,000 in annual energy costs.

• Little Rock Air Force Base: Conducted numerous energy conservation projects with $10 million invested, including the replacement of air-to-air heat pumps with high-efficiency ground source heat pumps (GSHPs) in more than 1,500 housing units.

• General Services Administration Chet Holifield Federal Building: One of the first Federal facilities to implement a comprehensive energy and water efficiency program, saving $640,000 in annual energy costs.

• U.S. Army Fort Knox: Extensive energy conservation projects and efficiency measures save the base $2.8 million due to reducing usage of 13.8 million kilowatt-hours of electricity and 280,000 cubic feet of natural gas.

• U.S. Marine Corps Base Camp Lejeune: Cut energy use by 33% in four housing areas by replacing outdated heating and cooling equipment with geothermal heat pumps.

• U.S. Army Fort Lewis: Utility partnerships and services help save more than $700,000 in annual energy costs.

• U.S. Postal Service: Two utility energy projects (in New York and Baltimore) cut energy consumption by as much as 44% in each location for a total annual savings of $460,000.

• Dallas Veterans Affairs Medical Center: Implemented the first thermal energy storage technology at a VA medical facility to reduce operating costs by $223,650 each year.

• White Sands Missile Range: Implemented a post-wide efficiency plan to reduce utility costs and implement a total solutions approach to resource management.

• National Aeronautics and Space Administration John F. Kennedy Space Center: Implemented energy conservation measures, including lighting and control upgrades, compressed air system replacements, chilled water system improvements, and ventilation controls in space shuttle service areas.
