The California Academy of Sciences located in San Francisco, CA is a ground-up, Type I, steel and concrete mixed-use museum project. The landmark cultural destination is designed by Pritzker Prize winning architect, Renzo Piano. This CMAR project totals 409,178 square feet throughout one structure with five levels above grade. This award-winning facility is made up of exhibit spaces, specimen collections, aquarium life support, auditoriums, laboratories and education spaces, administration, retail and food service, back-of-house support, and a central utility plant. Notably the center houses the Steinhart Aquarium, Morrison Planetarium, and Kimball Natural History Museum and supports over 18 million scientific specimens and 40,000 sea and land mammals, fish and reptiles. The design is highlighted by a 2.5-acre living roof which is rectangular in plan, but has undulating hills and valleys covered with native plants and is bordered by PV arrays integrated into a glass awning structure. The project included all underground utility infrastructure associated with the aquarium and existing research facilities stretching over a six-acre site. Along with the new De Young Museum of Art sited across a historic landscaped concourse, the Academy anchors a revitalized, and architecturally significant civic cultural complex and destination within San Francisco’s Golden Gate Park. Webcor self-performed concrete. This project received a rare double LEED Platinum® certification and is now recognized as the largest public Platinum-rated building in the world, and the world’s most sustainable museum building.
