The Academy of Sciences in California, by Italian architect Renzo Piano, winner of the Pritzker Prize, is the most sustainable museum in the world. Located in Golden Park, in San Francisco, the project is a renovation of a building from 1934. The museum is composed of many distinct areas, such an aquarium, a green space and a planetarium indoors, as well as various exhibition spaces that, unlike traditional galleries, were designed to receive a large amount of natural light. One of the most characteristic elements of the project is the enormous green roof, some 10,000 sqm (107,600 sqft), from which rise several large domes, also covered in plants.
