2019 Building Tours: The U.S. Capitol

By Better Buildings Beat Team on Jul 29, 2019

On July 9, D.C.-area properties opened their doors to 2019 Summit attendees to showcase their stand-out energy, water, and renewable efficiency measures. Below are highlights from one of the tours.

The Architect of the Capitol (AoC) – the federal agency responsible for the maintenance, operation, and preservation of the U.S. Capitol Complex – gave 2019 Better Buildings Summit attendees a behind-the-scenes look at its Energy and Sustainability program and a tour of the U.S. Capitol. Led by on-site Capitol staff and Alesia Wubben, the Sustainability Program Specialist for AoC, attendees walked through the Crypt, the Rotunda, and the National Statuary Hall. Prior to the tour, Alesia highlighted AoC’s ambitious goal of 50% energy reductions by 2025. The agency has reduced energy consumption by 31% over the last 10 years, largely due to the installment of a central cogeneration plant. Additionally, several energy savings performance contracts (ESPCs), direct digital control (DDC) upgrades, and the integration of renewables have enabled AoC to achieve $100 million in cost avoidance since 2005. Attendees learned about the challenges associated with integrating modern technologies in historic buildings and the processes in place for allocating capital to projects across the various “jurisdictions,” which includes a monthly working group with representatives from each of the historic buildings and grounds that make up the Capitol Complex.
