The concept of building efficiency is easy enough to grasp: ensure comfort and functionality while using less energy. Making that happen in a given building, however, isn't always straightforward. Achieving low-energy retrofits and good operations require well-trained technicians who know how to interpret building characteristics and energy data, which is why educators are interested in learning...

One Sunday evening, in 2007, Christian Kohler and his dinner date, Jina Shah, were presented with a most unusual check at Karma Kitchen, a monthly experiment in "pay it forward" dining served by volunteers at the Taste of the Himalayas, an Indian/Nepalese restaurant in downtown Berkeley.The price of their meal? Zero dollars. But it came with a karmic twist. They could pay it forward by paying for... Read more

Elementary school science teaches us that in the sun, dark colors get hot while white stays cool. Now new research from Lawrence Berkeley National Laboratory (Berkeley Lab) has found an exception: Scientists have determined that certain dark pigments can stay just as cool as white by using fluorescence, the re-emission of absorbed light.The researchers tested this concept by coloring cool roof...

About 10% of the energy used in U.S. buildings—approximately 4 quads a year—compensates for energy lost through windows. To address this inefficiency, architects, engineers, and home-builders are advocating the use of high-performance windows, which are composed of insulated glass units (IGUs) that combine multiple panes, thin film coatings, and special gas fills between the panes, and...
