California Construction - (Page 3) Northern California—Best of 2007 photovoltaic cells installed in the perimeter canopy system of the roof. • Daylight – 90% of all spaces occupied for critical visual tasks (research, collection and administration) will be provided with a minimum daylight and view factor of 2%. • Innovation – exhibits to promote sustainability will be showcased within the museum, including displays of the building itself as an example of sustainable practices. Modern programs for alternative transportation will also be incorporated for employees and visitors. • Water efficiency – the use of high-efficiency irrigation technology, such as microirrigation systems, moisture sensors, and weather database controllers will be incorporated to reduce water usage. • Indoor Air Quality – a permanent entryway system will be installed to capture dirt, particulate matter, and other pollutants from entering the building at all high volume entryways. The new building will rely on extensive natural ventilation for cooling. The openings in the roof domes will create a stack effect on the exhibit floors, drawing in fresh cool air from below and exhaling warm air out the roof. Academy staff will enjoy operable windows in their offices. • The living roof – the largest in the nation (2.5 acres), with the 1.7 million plants providing a thermal insulating layer for the building while reducing storm water run-off (estimated at 2 million gallons per year). • Wood use – at least 50% of the wood is Forest Stewardship Council-certified. • Insulation – the buildings walls are insulated with recycled cotton fiber from blue jeans. • Reduced heat island effect – in addition to the living roof system, a minimum of 30% of non-roof impervious surfaces (including parking lots, walkways, and plazas) will be under shade. << Project Team Owner California Academy of Sciences, San Francisco General Contractor Webcor Builders, San Francisco Architects Designed by Renzo Piano Building Workshop in collaboration with Stantec Architecture (formerly Chong Partners), Genoa, Italy, and San Francisco, respectively.
