Researchers in the Middle East have developed a new design for energy systems combining PV power generation with Trombe walls in buildings. They claim their new system configuration with reflective ...

Sunlight-reflecting "cool walls" have been shown to reduce energy costs by lowering heat gain in buildings. But they do more - reflective walls can also cool cities, fighting the urban heat island ...

If these walls could talk, they might tell you that cutting energy costs and pollution may be as easy as giving them a fresh coat of lighter, more reflective paint. A study by scientists at the U.S.

Cities across the U.S. have found relief from this summer’s record-setting heat with the help of technologies that shield roofs, pavement and other surfaces from the sun’s scorching rays. Some of ...
