Cool Roofs and Energy Efficiency in China

Posted by karen-smith-murphy on September 8, 2014

The Lawrence Berkeley National Laboratory (LBNL) has conducted the first comprehensive study of cool roofs in China and concluded that they would be an effective way to reduce energy use and greenhouse gas emissions.

Researchers ran simulations on residential and commercial buildings in seven cities in five climate zones, and found that light colored roofs reduced the need for air conditioning and energy consumption, and lowered the output of greenhouse gas trapping carbon dioxide.

LBNL scientist and lead author, Ronnen Levinson (member of GCCA’s Board) had this to say:

“Cool roofs have been well demonstrated in the United States, Europe, and elsewhere,” said lead author and Berkeley Lab scientist Ronnen Levinson. “While the concept is the same everywhere, we wanted to show that cool roofs would also be effective for Chinese construction, in Chinese climates, and with Chinese building operation practices.”
