The San Francisco Federal Building is currently participating for the BOMA Earth Award Certification. The building was designed by the Morphosis Architectural firm, as a supplement to the Phillip Burton Federal Building at 450 Golden Gate Avenue. The building was designed to be a 'green' building consuming less than half the power of a standard office tower. It has been recognized as the first Federal Building to be certified under the USGBC's Leadership in Energy and Environmental Design (LEED) for utilizing natural light to illuminate 80%. Additionally, it was the first naturally ventilated office building on the west coast since the advent of air conditioning. The building features some elevators which stop on every third floor to promote employee interaction and health.
