Cool Building Solutions for a Warming World

Extreme heat events were responsible for nearly 8,000 excess deaths in the U.S. from 1999 to 2009 and are expected to grow 5 to 10 times more frequent by the end of the 21st century as the climate warms. The Heat Island Group at Lawrence Berkeley National Laboratory is collaborating with the broader urban heat island (UHI) countermeasures community to identify and assess UHI countermeasures (e.g., high-reflectance surfaces, wet surfaces, shading) and other passive building energy efficiency strategies (e.g., increased thermal mass or ventilation) that help individuals and cities adapt to extreme heat events. 

We have convened an international working group of researchers and implementors to

  • understand the current state of science and implementation,
  • establish a set of standards for data collection, and
  • connect members to foster collaboration.


Berkeley Lab will host the first in-person meeting of working group in Berkeley, California on 22 - 23 July 2019. To learn more and register, please follow this link.
