NARRATIVE

240 Stockton is a historic art deco building located in San Francisco’s Union Square. Built in 1908 using recycled materials from the 1906 earthquake, 240 Stockton still today maintains a sustainable edge. Bently Holdings, the owner and property manager of 240 Stockton, hired stok to provide LEED for Existing Buildings Operations & Maintenance (EBOM) certification services. Despite its century-old shell, stok helped 240 Stockton improve its energy, waste and water consumption and other building operations towards LEED certification. The USGBC accepted all 67 credits that stok submitted, enabling the building to receive LEED Gold certification – a true accomplishment for a building of its age.

Upon the success of the EBOM certification, Bently Holdings is continuing to work with stok to provide LEED for Commercial Interiors (CI) certification services for Bently’s new headquarter build-outs on the 240 Stockton 7th and 8th floors.

What makes 240 Stockton even more unique is the requirement by Bently Holdings that all tenant build‐outs seek LEED for Commercial Interiors (CI) certification of Silver or higher. Bently Holdings is leading the charge by seeking a LEED Platinum certification for its office build-outs, and also offers tenants a stipend to pursue LEED certification – the only developer we know to be doing so today.
