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 about hands-on exercises and tools they can use...

While growing up in Fresno, California, Lab researcher Christopher Payne dreamt of becoming a particle physicist. But as the only child of a single mother with a limited income, he wasn't sure how he would pay for college. Payne thought he'd have to put his scientific pursuits on hold until one afternoon, during his sophomore year of high school, he received a letter from Carleton College, a liberal arts school in Northfield, Minnesota. He had... 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 coatings with ruby red (aluminum oxide doped with... Read More

Growth of Devices with Standby and Network Power
April 13th 2016
New technologies could significantly improve energy efficiency of televisions, gaming computers, pool pumps, and a variety of other plug loads. Plug loads, or devices that plug into the wall, are responsible for at least 25 percent of electricity use in California buildings. And not only is that percentage growing, it’s a hard number to manage since “plug loads” include hundreds of device types—from small appliances to electronics to lighting—... Read More

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 insulating frames to lessen unwanted heat transfer while...

Low-cost coating would disrupt the building retrofit market and potentially save billions in electricity. It’s estimated that 10 percent of all the energy used in buildings in the U.S. can be attributed to window performance, costing building owners about $50 billion annually, yet the high cost of replacing windows or retrofitting them with an energy efficient coating is a major deterrent. U.S. Dept. of Energy (DOE)’s Lawrence Berkeley National... Read More
