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. In our view, these studies taken together raise important...

The Energy Performance of Buildings group has a newly remodeled website. EPB works on problems associated with whole-building integration involving modeling, measurement, design and operation. Most of its tasks focus on the movement of air and associated penalties involving distribution of pollutants, energy and fresh air.
It's a grand challenge: develop clean, sustainable technologies that deliver a low-carbon energy future, and through innovation, create jobs, new markets, and exports, and increase America's energy security.
Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) have made it their mission to develop low-carbon and energy-efficient technologies such as advanced materials and information technology for buildings; next-generation... Read More
Nearly all cars sold in California have air conditioners. Cars painted with reflective coatings stay cooler in the sun and are easier to air condition to a comfortable temperature, according to a recent study by researchers in Berkeley Lab's Environmental Energy Technologies Division.
"Solar reflective paints can decrease the ‘soak' temperature of the air in a car that has been parked in the sun. This could improve the vehicle's fuel economy by... Read More

That fancy programmable thermostat on your living room wall, the one with a backlit digital screen, several tiny buttons, and unintelligible instruction manual, may be making it more difficult to save energy.
A research team at the Lawrence Berkeley National Laboratory (Berkeley Lab) is beginning to figure out why. They are determining how to measure the usability of a thermostat—that is, the ease of accomplishing the things people want to do... Read More
Not long ago, Japan faced a major power crisis. In September 2002, the Tokyo Electric Power Company (TEPCO) was forced to shut down 17 nuclear power plants for emergency safety inspections.
The winter of 2002-2003 was approaching, and the plants, which were expected to remain closed for months, would be unavailable through summer 2003, a time when demand from summertime air conditioning would normally require those plants to be operational to... Read More
