A new ultrathin multilayered material can cool buildings without air conditioning by radiating warmth from inside the buildings into space while also reflecting sunlight to reduce incoming heat.

Stanford engineers have invented a material designed to help cool buildings. The material reflects incoming sunlight, and it sends heat from inside the structure directly into space as infrared radiation (represented by reddish rays).
Stanford engineers have invented a revolutionary coating material that can help cool buildings, even on sunny days, by radiating heat away from the buildings and sending it directly into space.
