Coating Reflects Sunlight, Radiates Heat to Cool Buildings
STANDFORD, Calif., Nov. 26, 2014 — A thin-film coating has the potential to cool buildings by simultaneously radiating heat from inside and reflecting sunlight. The photonic radiative cooling material reflects incoming sunlight (the sun’s reflection seen on the panel) and sends heat from inside the structure directly into space as infrared radiation (reddish rays). The blue areas on the roof show the cooling effect. Courtesy of Nicolle R. Fuller/Sayo-Art LLC. Developed by a team at Stanford University, the...
