Buildings could be cooled with zero energy using the Invert shading system, made from a smart material called thermobimetal that changes shape in response to heat.
The invention of architect Doris Sung, Invert looks like a regular decorative shutter, but its metal pieces curl and flip over in the sun, altering how much light and heat can enter a space.
Huge amount of energy used to cool buildings
Sung, who is based at the University of Southern California School of Architecture, has been working with thermobimetals for years in the hope that they can help cut fossil fuel emissions from the heating and cooling of buildings.
The most recent, Fuller at the Los Angeles Municipal Art Gallery, was inspired by Buckminster Fuller's geodesic dome and used the material's special properties for the purposes of connector-free assembly instead of heat regulation.
