Under the green roof: Ground control in northern California
Lead architect Renzo Piano envisioned the new California Academy of Sciences (CAS) building as an organic part of its setting, San Francisco's Golden Gate Park. So his design crowned the building with a 2.5-acre living roof, a swath of native vegetation blanketing 7 mounds that echo throughout the surrounding hills. The new California Academy of Sciences building will help the 155-year-old institution fulfil its mission 'to explore, explain, and protect the natural world'. In total, the CAS building is 410,000 sqft, with about 100,000 sqft as public space. The roof is 197,000 sqft, which includes about 2.5 acres of green roof and 2 acres of solar panel canopy. The green roof is officially named The Osher Living Roof, in honour of the San Francisco-based Bernard Osher Foundation, which donated USD 20 million toward the new building. A viewing platform in one Corner will allow visitors to see the groundbreaking roof up close. In the Center, a glass ceiling allows natural light to fill the rain forest exhibit below. A band of 60,000 photovoltaic cells form a perimeter around the green roof; the cells are expected to generate approximately 213,000 kilowatt-hours of energy annually, fulfilling up to 10 % of the building's total electricity requirements. Designers did a feasibility study of existing green roof soil-retention products, but none proved suitable for the CAS building's severe slopes. Then architect Renzo Piano developed a biodegradable container that could be used to put the plants on the roof. BioTrays are 3in. deep and 17in. square, porous, interlocking, and biodegradable. The bottom layer of the CAS green roof is concrete. On top of that is the waterproofing layer: A hot-applied monolithic membrane (including fabric-reinforced assembly), a fluid-applied rubberized asphalt. One of the trickiest parts of designing a green roof system is choosing the green - that is, the plants. If the choices are wrong, the green roof could turn into a brown roof. Installation of the basic components of the green roof went as planned. The plants were irrigated through summer 2008 to help them get established. So far, they are thriving. Installation of the green roof continued through the summer of 2008 with the development of an exhibit garden, which surrounds the roof's visitor platform.
