Passive Cooling System can Reduce Cooling and Heating Costs, Reduce CO2 Emissions Written by AZoCleantechFeb 9 2021 Passive cooling is similar to the shade provided by trees, and this phenomenon has been around all the time. Image Credit: University at Buffalo. Lately, scientists have been investigating how a passive cooling technique—called sky or radiative cooling—can be turbo-charged with sun-blocking nanomaterials that remove heat away from the rooftops of buildings. Although advances have been made, this environmentally friendly technology is not an ordinary thing, because investigat...

University at Buffalo Radiative cooling. Solar heat. All from one system, no electricity needed. Study describes passive cooling system that aims to help impoverished communities, reduce cooling and heating costs, lower CO2 emissions Qiaoqiang Gan, professor of electrical engineering University at Buffalo School of Engineering and Applied Sciences BUFFALO, N.Y. — Passive cooling, like the shade a tree provides, has been around forever. Recently, researchers have been exploring how to turbo charge a passive cooling technique — known as radiative or sky cooling — with sun-blocking, nano...
