The 5th Annual Flex Your Power Awards

Heat Island Group, Lawrence Berkeley National Laboratory

Innovative Products and Services Award Winner

Heat Island Group, Lawrence Berkeley National Laboratory

The best way to cut summer cooling costs is to keep buildings from getting hot in the first place. Lawrence Berkeley National Laboratory (LBNL) has developed innovative cool roofing materials with solar reflecting pigments that will cut energy consumption in warm climates by 10-20%. This technology is innovative because it is not simply a reflective light color; it is an improvement to the reflectivity of dark-colored roof materials, which are preferred by U.S. consumers. This allows cool roof benefits to be integrated into all types of popular roofing materials. LBNL is working with a number of California companies to advance these technologies, and if California was to adopt them under title 24 it could save 65 GWh of electricity per year.
