WEST LAFAYETTE, Ind. — A new white paint that could reduce the need for air conditioning may find its way into the hands of roofing contractors.
Developed by engineers at Purdue University, the acrylic white paint maintains a lower temperature under direct sunlight than other commercial white paints, keeping surfaces up to 18 degrees Fahrenheit cooler than their ambient surroundings. With no heat buildup, researchers say there’s no need for air conditioners to turn on.
