San Francisco Federal Building

Architect: Morphosis

The San Francisco Federal Building is a powerful symbol of the government’s commitment to renewing the local community and providing a progressive, sustainable workplace.
The 18-storey tower is one of the only major US office buildings designed in the last half-century to be naturally ventilated, a strategy which helped meet the client’s goal of energy conservation. The tower façade’s “living skin” responds to outside conditions, and building systems monitor interior temperature and air pressure, automatically triggering motorized floor vents that maintain appropriate environmental conditions. By eliminating the need for a mechanical cooling system, we helped reduce construction costs by $11M and cut annual operating costs by $500,000.
Arup’s scope on the LEED® Silver-certified project included seismic design and structural, mechanical and electrical engineering.
