Researchers from Purdue University have developed a new white paint that can reflect over 95 percent of sunlight, which can cool the surface even lower than the ambient temperature. Painted on a building, the new paint could help cut cooling costs and energy use.

It’s a basic fact of physics that white surfaces and objects reflect more light, and therefore remain cooler. Theoretically, that could be harnessed to help keep buildings cool – after all, air conditioning is one of the biggest guzzlers of energy in the summer months, and studies suggest that painting buildings white can cool entire cities.
