Ameresco, Inc. announced that through a partnership with the Strategic Initiatives Division of General Services and with funding provided by Denver's Environmental Health Department, the City and County of Denver has entered into a nearly $2 million energy performance contract (EPC) with the company. Ameresco was pre-qualified by the Colorado Energy Office and Denver selected the energy service provider for the City's first-ever EPC. Under an EPC, an energy service provider implements energy and infrastructure upgrade improvements to a building or group of buildings and guarantees projected energy savings through a highly regulated measurement and verification process.

Any projected savings that are not attained are covered by the provider. Denver's EPC includes a total of 88 energy efficiency improvements to 14 of the City's most energy intensive buildings, including four recreation centers, four libraries, three fire stations, and the 911 Call Center. The improvements are guaranteed to create energy savings averaging 17% across all 14 buildings, with four of the buildings expected to reduce their energy use by over 30%.
