Sustainability Accomplishments

Through a successful sustainability and energy program, the Architect of the Capitol (AOC) has annually exceeded its energy reduction goals outlined in the Energy Independence and Security Act of 2007 (EISA 2007) and the Energy Policy Act of 2005 (EPACT 2005). The AOC is on pace to meet its 30 percent energy intensity reduction by the end of Fiscal Year 2015. In addition to energy reductions, AOC’s program efforts include progress sustainability components that strengthen the AOC’s facilities and help manage change for buildings designed without modern technologies in mind.
