The Exploratorium project included a major renovation to San Francisco’s two historic waterfront structures, Piers 17 and 15, along the Embarcadero to house the country’s largest net-zero museum. This two-story, 330,000 square-foot, LEED® Gold project included the installation and relocation of lighting packages, machine room equipment connections, and miscellaneous power receptacles, access control, card readers, and IP CCTV cameras. The Exploratorium features a restaurant, cafe, theater, offices, exhibit space, video production studio, classrooms, labs, wood shop, metal shop, server rooms, IDFs and retail areas to serve the more than 560,000 visitors the museum gets each year. In addition, CEI's Renewable Division procured the inverters and the combiner boxes installed for the 1 Megawatt (MW) solar photovoltaic (PV) infrastructure on the facility’s rooftop.
