Salesforce Tower is the tallest building in San Francisco, joining the Golden Gate Bridge and the Transamerica Building as one of the skyline’s defining elements. Standing 326 meters tall, the tower has the simple, timeless form of the obelisk, giving the 61-story tower a slender, tapering silhouette. The walls are composed of clear glass with pearlescent metal accents. These horizontal and vertical accents gradually taper in depth to accentuate the curved glass corners. The walls rise past the top floor to form a transparent crown that appears to dissolve into the sky. Carved into the tower top is a vertical facet that is lit at night. At its base, Salesforce Tower connects directly to the Salesforce Transit Center, which will house 11 Bay Area transit systems. On top of the transit center and linked directly to the tower is a 5.4-acre public park, which will offer recreational, educational, and nature activities. The park has two roles: the future anchor of the neighborhood and a key element of the project’s sustainable design strategy. Certified LEED Platinum, each floor of the tower has integrated metal sunshades, calibrated to maximize light and views while reducing solar gain. High performance, low-emissivity glass also helps to reduce the building’s cooling load. Cooling is provided in part by heat-exchanging coils wrapped around the tower’s foundations. The tower also has the largest blackwater recycling system in a commercial high-rise in the United States. High efficiency air-handlers take in fresh air on every floor.
