From Liisa O'Neill, Department of Energy, Office of Public Affairs:
Who knew leaks could be costing Americans $5 billion every year? And that's not water leaks—it's leaks you can't even see. Typical air duct systems, both residential and commercial, typically lose 25-40 percent of heating and cooling energy, accounting for billions added to utility bills.
But what if there was a simple mist that could seal thousands of leaks in 4 to 8 hours,... Read More
KQED Quest covered energy-efficient windows research at Berkeley Lab. EETD researchers Howdy Goudey and Stephen Selkowitz are quoted, along with Delia Milliorin of Berkeley Lab's Molecular Foundry. Read the story and listen to the audio report.
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
Teaming up to fight against escalating energy costs, the Department of Defense, Lawrence Berkeley National Laboratory (Berkeley Lab), and Philips Corporation are demonstrating advanced energy-efficient lighting controls technologies in Fort Irwin, California.
"The purpose of this study is to demonstrate that these technologies work in typical applications and buildings at Fort Irwin, and to provide the technical experience and data to support... Read More
NASA's Ames Research Center and the Department of Energy (DOE), at the Lawrence Berkeley National Laboratory, Berkeley, Calif. are collaborating on technologies and processes for what may be the "greenest," highest-performing building in the federal government.
