SFPUC previews 525 Golden Gate headquarters: wind turbine, water harvesting and LEED Platinum goal
Summary
Project director Shelby Campbell told the commission the new SFPUC headquarters at 525 Golden Gate will pursue LEED Platinum, include a wind turbine, rainwater/graywater harvesting (≥3,000-gallon storage), childcare, and a local-hire emphasis; construction expected to start in May with completion targeted in 2012.
Shelby Campbell, project director for the SFPUC’s new headquarters at 525 Golden Gate, presented design development and a construction schedule on Jan. 12, 2010. Campbell described sustainable design features that will be pursued to achieve LEED Platinum and to demonstrate innovations in energy and water use.
Key features: Campbell described a public lobby with a visible wind turbine, a two‑level childcare center and a grand interior stair. The building plan includes on-site stormwater and graywater treatment, and a basement storage tank of at least 3,000 gallons to supply nonpotable uses when rainwater is insufficient. "We're going beyond maximum credits available for water efficiency... We will have a treatment for both stormwater and gray water and a 3,000 gallon or greater storage tank in the basement," Campbell said.
Energy and sustainability goals: the design team is targeting a combination of solar and on-site renewables; Campbell said the building could generate a share of its power with on-site renewables and that the design team is pursuing every available LEED innovation credit as a teaching tool.
Schedule and procurement: demolition and micropile work are under way; micro-pile installation is scheduled through March, crane installation in April and above-grade work to start in May. Contractors report packaging work with local-hire targets; the project team said early trade packages for demolition, micropiles and curtain wall came in under budget.
Next steps: staff will continue design development, validate costs with detailed estimates and return with construction documents and outreach for May bid packages. The PUC expects to use the building as a demonstration project for urban sustainability and to publicize building performance via a lobby dashboard for energy and water metrics.
