Accomplishment 

A Berkeley Lab-led team of scientists established a method to simulate soiling and weathering of roofing material, reproducing in the lab in only a few days what would naturally take three years. This “cool roof time machine” protocol has been approved by ASTM International, a widely referenced standards body, as a standard practice for the industry, and is expected to accelerate deployment of cool roofs, which have been shown to reduce a building’s energy use and mitigate the urban heat island effect.
