Cool roofs in China offer enhanced benefits during heat waves

It is well established that white roofs can help mitigate the urban heat island effect, reflecting the sun's energy back into space and reducing a city's temperature under normal weather conditions. In a new study of Guangzhou, ...

A super cool roof solution to being hot in the city

Sydney materials scientists are claiming a breakthrough in cool roof technology with a surface they've developed that will stay cooler than the ambient air temperature, even under the mid-summer Australian sun.

New 'cool roof time machine' will accelerate cool roof deployment

Cool roofs can help keep buildings cool, thus lowering the building's energy use, while also mitigating the urban heat island effect by reflecting sunlight away from buildings and cities. But as cool roofs age and get soiled, ...

Cool roofs in China can save energy and reduce emissions

(Phys.org) —Working with Chinese researchers, the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has conducted the first comprehensive study of cool roofs in China and concluded that they would ...

White, green or black roofs? New report compares economic payoffs

Looking strictly at the economic costs and benefits of three different roof types—black, white and "green" (or vegetated)—Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have found in a new study that ...
