SPECIAL PAINT—Scientists have created a white paint that, when applied, can reduce the surface temperature on a roof and cool the building beneath it. ➡️The paint’s properties are almost superheroic. It can make surfaces as much as 8 degrees Fahrenheit cooler than ambient air temperatures at midday, and up to 19 degrees cooler at night, reducing temperatures inside buildings and decreasing air-conditioning needs by as much as 40 percent. It is cool to the touch, even under a blazing sun, Dr. Ruan said. Unlike air-conditioners, the paint doesn’t need any energy to work, and it doesn’t warm the outside air.
