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.

U.S. Department of Energy Announces Berkeley Lab Funding to Develop Energy-Efficient Window with Smart Automated Shading System

December 21, 2012

The U.S. Department of Energy today announced that it will fund the Lawrence Berkeley National Laboratory (Berkeley Lab) to develop a highly insulated energy-efficient window system with a smart automated shading. The project’s principal investigator is Stephen Selkowitz of the Environmental Energy Technologies Division (EETD), and leader of the Windows and Envelope Materials Group. Berkeley Lab will receive up to $1.5 million in funding.

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.

Heat Island Group shares cool science with public at LBNL Open House

On Saturday, October 13, Berkeley Lab welcomed more than 7000 visitors to explore the science and research conducted each day at LBNL.

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.
