San Francisco — Designed by Skidmore, Owings & Merrill LLP (SOM), 350 Mission was awarded LEED Platinum certification, the highest level of achievement in green building granted by the U.S. Green Building Council (USGBC). Scheduled to officially open this summer, 350 Mission Street is a 30-story office tower located in downtown San Francisco. According to SOM, the project exemplifies a regenerative urban ecology in which environmental, social, cultural, and economic sustainability is applied to the making of the architectural form.

A 50-foot-high urban living room at the building’s base is designed as a vibrant space that blurs the boundaries between public and private realms. Cutting energy costs by one-third, energy conservation strategies include zoned under-floor HVAC distribution and high-performance, insulated glass cladding units that reduce solar heat gain while maximizing visibility and daylighting.

Utilizing a highly innovative structural system and recycled construction materials, the design reduced the building’s embodied carbon, as well as the length of the construction schedule. Additional sustainability strategies include stormwater harvesting for non-potable uses and the allocation of space for bicycle storage and charging stations for electric vehicles.

Salesforce will be the sole tenant of 350 Mission, which is being developed by Kilroy Realty Corporation & Management.
