The Architect of the Capitol's (AOC) commitment to sustainability is demonstrated through our robust energy conservation and sustainability programs. The agency incorporates sustainable design and construction practices into the major projects executed throughout Capitol Hill.

The AOC has set goals for energy reduction, water conservation and waste diversion to drive continuous improvement and embed sustainability into its operations and workplace culture. In fiscal year (FY) 2024, the AOC diverted 35 percent of building occupant waste, 93 percent of construction and demolition debris and 10 percent of food and all green waste from landfills.
Recycling Programs
AOC recycling programs address building occupant waste and construction and demolition waste. The AOC continually evaluates its recycling program and analyzes waste streams through solid waste audits and pilot initiatives to identify new materials for recycling and improve the recycling diversion rate.
Metal, electronics, and paper and cardboard recycling contribute to the Recycling Program Revolving Fund to support environmental stewardship. In FY 2024, five projects valued at $470,000 were implemented across the Capitol campus. This included energy efficient electric boilers at the Library of Congress, new electric mowers for the Capitol Grounds and Arboretum, a Senate food service study to improve sustainability, a U.S. Botanic Garden (USBG) roof project with sustainability features that may include a green roof, solar panels and a rainwater harvesting system and implementation of a campuswide Small Battery Recycling Program to ensure all batteries are recycled safely, efficiently and at a lower cost to the AOC.
