Recommendation
No objection to the modified final design for new boiler plant equipment at the National Building Museum located at 401 F Street, NW, per materials received 1 October 2026. Scope consists of a building-wide energy retrofit including the installation of a natural gas-fired hot water boiler plant, a gas meter, and flues within an existing cooling tower enclosure on the northwest corner of the site. This project is one component of a larger initiative, the National Deep Energy Retrofit, which is an energy conservation program for federal buildings. The project was approved by the Commission in 23 January 2026 and is now proposing to reduce the total number of exhaust flues from four to three.
