You have to read it three or four times and it will still sound confusing. Researchers at the University of Colorado Boulder created a material, which is able to keep buildings cool. In case it should be applied one day, it might be possible to reduce loads of energy-intensive air conditioning systems. This would be worthwhile due to the enormous energy consumptions of air-conditioning units all over the world. Reason enough to take a closer look at their findings. The scalable manufactured metamaterial is able to lower building temperatures independently even when they are exposed to direct sunlight. The thin plastic film cools buildings by reflecting the incoming solar rays into the atmosphere. At the same time, it is possible to shed the building’s heat as infrared thermal radiation. These properties are, allegedly, not found in nature.
The Thin Plastic Film Cools Buildings by Emitting Thermal Energy and Barely Absorbing Sunlight
“Just 10 to 20 square meters of this material on the rooftop could nicely cool down a single-family house in summer,” said Gang Tan, an associate professor in the University of Wyoming’s Department of Civil and Architectural Engineering.
