Witryna21 paź 2024 · The white paint that Purdue researchers created reflects 95.5% sunlight and efficiently radiates infrared heat. Developing this paint formulation wasn’t easy. The six-year study builds on attempts going back to the 1970s to develop radiative cooling paint as a feasible alternative to traditional air conditioners. WitrynaStudies show that a recently-developed reflective paint can help keep buildings cool by reducing the surface temperature of exterior walls by a stunning 28°F (15.6°C), … Witryna28 lis 2024 · Is there a paint that reflects heat? Now researchers have made an ultra-white cooling paint that reflects up to 98 percent of the sun’s heat. White cooling paints are an established cooling technology that help bring down indoor temperatures and thus save the electricity used for air-conditioning in hot climates. chr ord b 32
