A diverse group of 20 organizations has drafted a letter (Heat in Federal Policy 7_29_21) to leaders in the White House and Capitol Hill to highlight the opportunity to include resilience to extreme heat in federal infrastructure talks. The letter highlights the various short and long term investments to strengthen our communities to the threat of extreme heat that also deliver tremendous economic benefits to U.S. citizens and businesses.
A new paper now in press in Energy and Buildings highlights local and state initiatives to advance cool roofs, cool pavements, and urban vegetation in California and beyond.
In particular, the paper reviews efforts that two of California’s largest school districts have undertaken to deploy cool community measures to keep schoolyards cooler and reduce energy bills. The paper also updates how cool community measures are being included as components of local climate action and adaptation plans and of California’s statewide guidelines for extreme heat adaptation.

In 2006, California introduced the Global Warming Solutions Act (Assembly Bill 32), which requires the state to reduce greenhouse gas emissions to 1990 levels by 2020. “Cool community” strategies, including cool roofs, cool pavements, cool walls and urban vegetation, have been identified as voluntary measures with potential to reduce statewide emissions. In addition, cool community strategies provide co-benefits for residents of California, such as reduced utility bills, improved air quality and enhanced urban livability. To achieve these savings, Lawrence Berkeley National Laboratory (LBNL) has worked with state and local officials, non-profit organizations, school districts, utilities, and manufacturers for 4 years to advance the science and implementation of cool community strategies. This paper summarizes the accomplishments of this program, as well as recent developments in cool community policy in California and other national and international efforts. We also outline lessons learned from these efforts to characterize successful programs and policies to be replicated in the future.
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!
