One Sansome Street

San Francisco, CA
Certification: Version 4 Platinum

How we solved the challenge

One Sansome Street sits atop a base that includes portions of a historic building that once housed the Anglo & London Paris National Bank. When it was acquired by Barker Pacific Group and Prudential Real Estate Investors, the occupancy had fallen to 75% and common areas needed refurbishing. The BPG and Prudential joint venture is investing about $20 million to upgrade the building, and the capital improvements will include renovating the historically significant atrium area.

BuildingWise was called in to re-certify the whole building, and after our assessment, we encouraged Barker Pacific to undertake the new LEED EB Version 4, as well as undertake a LEED CI for a large incoming government tenant. In August, 2014, the building received Platinum certification.
