One Sansome Street, San Francisco is the first building in the U.S. to achieve LEED Platinum v4 certification. The building is also only the second property worldwide to be awarded with v4 certification.
Currently under the ownership of Barker Pacific Group, the office tower totaling 611,000 sf of net leasable space was originally developed in 1983. The property previously received LEED Gold-level certification in 2010.
The owner continued to make improvements to the property’s systems to increase energy efficiency and reduce the amount of waste produced by the building. The 41-story office building now has a solid waste diversion rate of more than 78%.
The building’s scorecard on the United States Green Building Council’s website shows that One Sansome Street was rated with 80/110 in the review process for Platinum certification.
