'Smart roofs' can keep you cool and save energy
Engineers at Oak Ridge National Laboratory in Tennessee have developed a system which can be installed in your roof and attic to soak up the sun’s heat during the day and then release it back into the sky at night - keeping houses cooler. “This could reduce the cooling bill for houses by up to 8 per cent,” says Bill Miller, a member of a team testing roof and attic energy-saving systems at Oak Ridge. “We’re able to intercept 90 per cent of the heat energy that would otherwise penetrate into the living space through the attic floor,” he says.
