As a part of Berkeley Lab's ongoing Science Video Glossary, scientists from the Heat Island Group discuss the team's research. Watch Project Scientist George Ban-Weiss explain the causes and effects of the urban heat island effect, as well as Berkeley Lab's efforts to mitigate... Read More
(Reuters) - Converting the world's roofs from dark colours to reflective white would cancel the warming effect of 1 billion tonnes of carbon dioxide each year for the lifetime of the roof, according to former California Energy Commissioner Arthur Rosenfeld. The reduction in... Read More
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... Read More
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 ... Read More
On Saturday, March 16, the Heat Island Group added two new cool pavement coatings to the Bevatron Lot at Berkeley Lab. The new additions feature Western Colloid Armor Top asphalt-based coatings in two colors - Stealth Gray (near in image at right) and California Tan (far). The... Read More
Australian radio program "Beyond Zero" discusses building design and the urban heat island effect with the Heat Island Group's Haley Gilbert.
The University of California Office of Research has released an infographic to highlight the phenomenon known as the urban heat island effect. In three illustrated panels, the graphic shows what characterizes and causes urban heat islands, drawing from Heat Island Group research... Read More
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. But there are down-to-earth versions of the... Read More
Last week, 30 members of the China National Building Waterproof Association, which represents Chinese roofing manufacturers, and Chinese government officials came to Berkeley Lab for a daylong workshop on cool roofs. Their visit took place as part of the cool-roof project of the... Read More
On February 1, 2013, President Obama presented the 2011 National Medals of Technology and Innovation. Among the recipients was Arthur Rosenfeld, Distinguished Scientist Emeritus in the Environmental Energy Technologies Division at Berkeley Lab, who was recognized for his role in... Read More
HIG Research Assistant Ben Mandel discusses Berkeley Lab's cool pavement efforts, including Berkeley Lab's very own Cool Pavement Showcase: On sweltering days you can fry an egg on them. But, now, Lawrence Berkeley Lab and UC Davis researchers are testing surfaces designed to... Read More
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... Read More
On Saturday, October 13, Berkeley Lab welcomed more than 7000 visitors to explore the science and research conducted each day at LBNL. The Heat Island Group had the chance to interact with the general public, informing them about the basics of "cool science" (how reflective... Read More
On those sweltering summer days—when it's too hot to play at the playground, when it seems like you could fry an egg on the pavement, when your car feels like an oven after a couple hours parked at the mall—it's not just the beating sun that's driving up the temperature. It's... Read More
"Cool Your School" is a series of 6th-grade, classroom-based, science activities rooted in Berkeley Lab's cool surface and cool materials research and aligned with California content standards for science education. The activities are designed to build knowledge, stimulate... Read More
