Berkeley Lab researchers showcase cool pavement technologies

September 11, 2012

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 our very urban environment, in which most of our paved surfaces are dark, absorbing almost all of the sunlight that shines down on them.

Heat Island Group helps bring cool science to sixth graders through "Cool Your School" program

July 28, 2012

"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 curiosity, and carry the conversation about human-induced climate change, and what can be done about it, into the community.

Cool Roofs and Global Cooling: A Response to Jacobsen and Ten Hoeve (2011)

November 09, 2011

A recent Journal of Climate paper by Stanford's Mark Jacobson and John Ten Hoeve (2011) on urban heat islands and cool roofs is a useful contribution to the literature. However, their results regarding white roofs are preliminary and uncertain. Along with our own work at the Lawrence Berkeley National Lab, other published papers have addressed the broader benefits of white roofs.
