One Bush is a 50-year-old, multi-tenant building that has achieved LEED Platinum with no major retrofits.
One Bush Street was originally constructed in 1959 and renovated (asbestos abatement and sprinkler upgrade) in 1990. Including 298,778 square feet of office space, along with a separate circular retail building, One Bush occupies an entire city block. The office building has three basement floors and 19 floors above-grade. The main floor of the office building is entirely occupied as a lobby and is smaller than the building footprint (floors two through 19 are larger than one). The office building offers space to between 20 and 25 tenants at any given time.
One Bush is owned and managed by Tishman Speyer. Tishman Speyer launched a LEED program across our portfolio, realizing that the LEED certification program paralleled our internal sustainability goals. As part of this, we began pursuing LEED certification on One Bush Street’s office building and other west coast assets in the spring of 2010 in order to accomplish three main goals:
To reduce overall impact of operations on the environment To create a more positive and enjoyable working environment for our tenants To increase profitability of our asset We intend to recertify One Bush under LEED for Existing Buildings: Operations & Maintenance in 2014.
One Bush Street, which was originally slated to pursue a LEED Gold certification, re-evaluated mid-way through the LEED process and realized that with the whole team thinking creatively about alternative solutions and processes, we could obtain Platinum. Through careful project management, choosing the right consultants, and by including key players from different departments at Tishman Speyer to participate in weekly calls, our team achieved the certification with only two additional months of work.
In the end, One Bush Street invested $94,000, or $0.31 per square foot, to obtain the highest level of LEED certification. With both soft costs and hard costs falling far below the average, One Bush is the first multi-tenant building older than 50 years with no major renovations in the Bay Area to obtain the prestigious LEED Platinum certification. It is also the sixth building in San Francisco, and 46th in the United States, to obtain LEED for Existing Buildings: Operations & Maintenance Platinum certification. This achievement and the cost at which it was obtained speak highly to the efficiency of the building management and operations.
