Buildings coated in a cement-based paint that “sweats” could help keep communities cool during the hottest days of the year. The substance is known as CCP-30, and its creators say initial tests ...

A team of chemical engineers has published a paper suggesting that we could one day replace air-conditioning units with polymer roof mats that encourage buildings to sweat, like humans, to cool down ...

Buildings are already being painted white to help keep them cool. As temperatures increase, this new addition to the paint could help lower our massive air conditioning energy use.

New colour paint designed to cool buildings by reflecting the sun could become an eco-friendly alternative to air conditioners, US materials scientists report.
