The United States General Services Administration (GSA) oversaw two properties, the 911 Building and the 905 Building, both of which were inefficient and consuming more energy than baseline buildings of a similar size. The 911 Building is an 11-story, 302,000 SF building with a parking garage and the 905 Building is an eight-story, 701,000 SF building with a parking garage.
GSA partnered with Heery to perform an energy survey and retro-commissioning services. Heery investigated the Heating, Ventilation and Air Conditioning (HVAC) and lighting systems, and developed energy models to analyze the proposed recommendations. Heery’s careful investigation and consultation helped the GSA to determine which energy conservation measures would have the most meaningful impacts on building performance and energy use.
Funded through the American Recovery & Reinvestment Act (ARRA) appropriation, this project resulted in a significant reduction in building operation costs and energy use for the GSA while also improving the comfort of building occupants.
