The Power of Cool Coatings!

The Northern Cape Province of South Africa is mainly semi-desert. In January, afternoon temperatures usually range from 34 to 40 degrees Celsius. In 1939, an all time high of 47.8 degrees Celsius was recorded at the Orange River.

Summer temperatures often top the 40 degree mark in this region (104 Fahrenheit).

This video explains how cool surfaces can help reduce indoor temperatures and improve the quality of life of those living in low-income housing in this scorching environment.

Reflective surfaces are cool in more ways than one, reducing energy consumption and saving lives one building at a time!

Video Explains How Reflectivity Can Change Over Time

GCCA Board Member and researcher at the Lawrence Berkley National Laboratory’s Heat Island Group, Ronnen Levinson, explains how the reflectivity of cool roofing materials can change over time in this new video. He also introduces LBNL’s new California Cities Albedo Map, which estimates the reflectivity of roofs in five California cities.
