High energy bills from cooling your home in the Summer could be a thing of the past. A team of researchers at Purdue University have invented "radiative cooling paint."
They claim this new white paint can keep surfaces up to 18 degrees cooler than the temperature around it by reflecting heat away from whatever surface it's painted on. While your average white paint can reflect between 80%-90% of sunlight, it can't help reduce room temperatures. In contrast, this new paint bounces back 95.5% sunlight.
A Ph.D student at Purdue, Joseph Peoples, says, "Your air conditioning kicks on mainly due to sunlight heating up the roof and walls and making the inside of your house feel warmer. This paint is basically creating free air conditioning by reflecting that sunlight and offsetting those heat gains from inside your house."
