Energy Savings At-A-Glance

“The AOC approaches energy and sustainability in terms of buildings, infrastructure and people – from the nation’s historic spaces, to the infrastructure that supports it, to the people that work or visit within our spaces. I believe it’s important for everyone to be engaged in preserving and maintaining our buildings.”

— Stephen T. Ayers, FAIA, LEED AP, Architect of the Capitol
