HIG researchers uncover potential for cool roofs in Chinese cities

Thursday, August 21, 2014

After three years of collaborative investigation, Ronnen Levinson and Jing Ge of LBNL's Heat Island Group co-authored a paper with Chinese researchers titled, "Cool roofs in China: Policy review, building simulations, and proof-of-concept experiments." Their work characterizes the potential for heat island mitigation, energy use, energy cost, and ambient air quality as a result of replacing dark gray roofs with aged white roofs in seven Chinese cities. Simulations and experiments yielded positive results for white roofs in the four hot-summer cities, leading the authors to conclude that cool roofs should be credited or required in building energy efficiency standards for all hot-summer climates in China.
