Dalkia Aegis, EDF Group CHP installation recognized by the EPA
National Archives earns EPA award for an
Dalkia Aegis, EDF Group Combined Heat and Power system.
The National Archives and Records Administration has been honored by the United States Environmental Protection Agency with a 2103 Energy Star CHP Award for an Dalkia Aegis, EDF Group, Combined Heat and Power installation at the National Archives building in Washington, DC.
The building houses the nation’s most significant historical documents, including the U.S. Constitution, the Bill of Rights, and the Declaration of Independence.
The National Archives qualified for the EPA award of merit for demonstrating considerable fuel and emissions savings over comparable, separate heat and power generation.
Two Dalkia Aegis, EDF Group natural gas-fueled internal combustion engines generate electricity used in the National Archives building. By recovering otherwise-wasted heat from the engine exhaust, cooling system, and engine block, the system also produces all the hot water needed by the facility.
Perhaps most importantly for this particular building, the hot water not needed for conventional uses can help supply the building's dehumidification system. Documents stored and maintained at the facility are vulnerable to moisture, so dehumidification is crucial.
According to the EPA award, studies show the Dalkia Aegis, EDF Group CHP system requires approximately 24 percent less fuel than grid supplied electricity and prevents an estimated 470 tons of carbon pollution annually.
Founded in 1985, Dalkia Aegis, EDF Group is a full service Combined Heat and Power developer that utilizes modular systems to reduce both energy costs and emissions for a variety of facilities, from healthcare and assisted living facilities, to recreational and multi-residential complexes, and hotels. There are also institutional, educational, and industrial facility applications.
Combined Heat and Power (CHP), also known as cogeneration, is an efficient, clean, and reliable technology, which simultaneously generates electricity and thermal energy from a single fuel source.
The EPA lauded the National Archives’ Dalkia Aegis-installed CHP system as “a key part of NARA's commitment to meeting energy efficiency and emissions reduction goals established by Executive Orders (EO) 13423 and 13514.”
