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,... Read more

New materials are crucial to building a clean energy economy—for everything from batteries to photovoltaics to lighter weight vehicles—but today the development cycle is too slow: around 18 years from conception to commercialization. To speed up this process, a team of researchers from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the Massachusetts... Read more

Current standards for U.S. offices require approximately 8 liters per second (L/s) of outdoor air ventilation per person. Providing twice as much ventilation would reduce sick building syndrome symptoms (SBS) and absences, improve work performance, and provide billions of dollars in annual economic benefits in the U.S., according to a recent study from the Lawrence Berkeley National Laboratory...

Lithium-ion batteries are everywhere, in smart phones, laptops, an array of other consumer electronics, and the newest electric cars. Good as they are, they could be much better, especially when it comes to lowering the cost and extending the range of electric cars. To do that, batteries need to store a lot more energy. The anode is a critical component for storing energy in lithium-ion batteries.... Read more

A new policy brief on the value of energy performance and green attributes in buildings, authored by Elizabeth Stuart, is available. Labels, certifications, and rating systems for energy efficiency performance and "green" attributes of buildings have been available in the U.S. for over 10 years, and used extensively in the European Union and Australia for longer. Such certifications and ratings... 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.
