5. California Academy of Sciences[/fusion_builder_column]
San Francisco, California
One of the weirdest buildings on this list, the California Academy of Sciences has a roof with a life of its own. The roof, which is covered in six inches of soil that helps insulate the building, also contains 60,000 photovoltaic cells that supply at least five percent of the Academy’s energy needs per year. A regulated air system also uses natural air currents to regulate temperature inside the building.
