The brand new paint differs from customary white paint, which displays solely 80% to 90% of daylight. That stops such paint from cooling the floor it coats.
In contrast, utilizing the new paint over a roof space of about 1,000 sq. toes may create a cooling energy of 10 kilowatts. Xiulin Ruan, a professor of mechanical engineering at Purdue, notes that such an impact is “more powerful than the air conditioners used by most houses.”

In accordance with a Purdue press release:
“Two features make this paint ultra-white: a very high concentration of a chemical compound called barium sulfate — also used in photo paper and cosmetics — and different particle sizes of barium sulfate in the paint.
