We’ve got white roofs, so how about pastel pavement?

April 01, 2013

OK, team, you know this concept. Cities are full of dark surfaces that absorb and capture energy from sunlight, creating islands of hot, hot heat. We all get sweaty, we turn up the A/C, that makes the city hotter, everyone suffers. This is why it's a good idea to paint roofs white.

Los Angeles strengthens commitment to cool roofs

March 31, 2013

Mayor of Los Angeles Antonio Villaraigosa has directed the Department of Building and Safety to incorporate cool roof requirements in its building code. Mayor Villaraigosa is also asking the Department of Water and Power (LADWP) to create incentives that make it financially attractive for homeowners to install cool roofs.

Coolest Notions Pay Off

February 08, 2013

When it comes to high-tech possibilities for counteracting climate change, the headlines tend to focus on the seemingly sci-fi stuff: brightening clouds, pumping particles into the stratosphere and launching giant mirrors into space.

Big Energy Savings in The New York Times Building Confirmed by Berkeley Lab Study

February 05, 2013

Designing a building holistically, and making sure that its components and systems work together according to design intent, can pay big dividends in energy savings and occupant satisfaction, according to a study by scientists at the Lawrence Berkeley National Laboratory (Berkeley Lab) of the performance of The New York Times Building in New York City.

Heat Island Group researchers contribute to passage of California's AB 296 for cool pavements

October 14, 2012

California Governor Jerry Brown has signed Assembly Bill 296, which calls upon the California Department of Transportation to develop a standard specification for sustainable or cool pavements that can be used to mitigate urban heat islands. Cool pavements absorb less sunlight than conventional pavements, helping reduce surface and air temperatures in cities.
