This San Francisco Public Utilities Commission (SFPUC) new 13-story, 277,000 square-foot office tower was designed with cutting-edge sustainable technology intended to make the building one of the most energy-efficient in the country. The LEED® Platinum-certified building’s 150 kilowatt (kW) solar photovoltaic system, four wind turbines, a custom weather monitoring station and ambient lighting control system were all installed by CEI to reduce energy consumption by 55 percent and lower energy grid demand 32 percent.
The new headquarters’ state-of-the art, roof-mounted monitoring station reports solar panel and wind turbine power generation, matching and controlling the input of external power based on real-time data from the SFPUC solar panels and wind. The ambient lighting control system brightens and dims indoor lighting, according to daylight levels. The building also features a greywater recycling system and raised flooring for in-floor air distribution.
CEI installed the building’s electrical systems, including emergency power, lighting, dimming/control, fire alarm and security, as well as low-voltage telecommunications and fiber optic data, and the parking garage system. CEI's Building Information Modeling (BIM) team created a state-of-the-art 3D models to plan and coordinate pre-construction efforts. In addition, CEI installed a specialty mechanical smoke control system and sound-masking technology that generates pink noise to enhance the work environment of SFPUC employees.
CEI's San Francisco location, experience and partnership with various sub-trades and Local Business Enterprise (LBE) electrical firms allowed the project to exceed the 20 percent (20%) LBE participation required by the SFPUC.
