The California Academy of Sciences has the largest green roof in North America. Covering the 400,000-square-foot building, replacing a complex damaged beyond repair roof by earthquake, is an undulating 2.5-acre living roof dotted with porthole-like skylights. This rolling landscape was conceived as a swath cut from the park and elevated 36 feet to the height of the old buildings.
