Sustainability, Energy and Water Conservation Management Report - Capitol Building Aerial

The Architect of the Capitol releases an annual energy report to highlight efforts to reduce energy use.

As stewards of the U.S. Capitol and as a legislative agency, the AOC is required to meet annual reductions in energy consumption and report annual progress. The annual energy report was created to inform Congress and the American people of the AOC’s progress on meeting its efficiency goals as well as its further commitments to sustainability and water efficiency. It includes details on the AOC’s approach, achievements, and areas identified for future progress.
