Cherrydale Library
At the Cherrydale Library, the AIRE program and Facilities Management retrofitted the lighting in 2008, realizing a 15% cut in electricity use. In 2009 AIRE replaced the aging heat pumps with new, ENERGY STAR qualified models, and replaced an electric tank water heater (in an unconditioned space) with a tankless water heater to cut energy use even further. The building is partially earth-bermed, providing natural insulation to help keep energy use in check. Cherrydale Library is now among the very most efficient buildings in the Arlington government inventory.
