Ultrathin, Multilayered Coating Material Radiates and Reflects Heat for Cooler Buildings

An new ultrathin, multilayered coating material paves the way to passively cooled buildings by providing a "one-two punch" approach, to remove heat from within the building whilst reflecting away sunlight.

The material, developed by a team of engineers at Stanford, uses a concept they call "photonic radiative cooling". This radiates the building's heat away as infrared light, whilst also acting as an efficient mirror, reflecting 97% of the incident sunlight to reduce incoming heat.
