50 United Nations Plaza is a historic building in the heart of San Francisco’s Civic Center which was completed in 1936. Hathaway Dinwiddie’s recent work there involved a complete historic renovation, seismic retrofit, and interior reconfiguration of the 5-story Federal Building. Sustainable design and construction principles were utilized in the context of preserving the historically significant building. Such methods include the replacement of the old roof with a new, living roof, extensive natural ventilation, energy-efficient lighting, and natural “California-scape” vegetation. 50 United Nations Plaza is a centerpiece of the General Services Administration’s ambitious effort to reduce or eliminate the environmental footprint of its 10,000 government buildings.

50 United Nations Plaza has achieved LEED Platinum Certification.
