Ameresco, Inc. announced that construction is underway for a $33 million Energy Savings Performance Contract (ESPC) at the U.S. National Archives and Records Administration (NARA) sites in College Park, Maryland, and Washington, DC. The project is designed to enhance energy efficiency across NARA's facilities, leveraging Ameresco?s innovative solutions to achieve significant cost savings and environmental benefits. This NARA ESPC project is the latest in a series of energy projects that Ameresco has undertaken in collaboration with NARA over the past 20 years.

Ameresco is implementing building automation system (BAS) modernization with advanced sequencing, optimization of heating and cooling systems, building transformer replacements, LED lighting, building envelope improvements, piping insulation, and utility water reduction at NARA?s flagship facilities. Together, these measures are designed to reduce annual fossil fuel consumption by 72%, utility water use by 48%, and electricity use by 28%. Thanks to a grant from the U.S. Department of Energy?s Assisting Federal Facilities with Energy Conservation Technologies (AFFECT) Program, NARA and Ameresco are now collaborating to add more energy efficient infrastructure into the project featuring more solar rooftop PV, a new chiller, and electrical vehicle (EV) Charging.

The ESPC delivery model was critical to NARA?s ability to replace aging infrastructure and reduce their energy consumption and carbon emissions. On previous ESPC projects supporting NARA, Ameresco deployed high-efficiency equipment to address legacy infrastructure issues, harvesting substantial savings. This latest ESPC is focused on bringing NARA?s facilities closer to net-zero emissions as required by Executive Order-14057.
