Two projects on residential buildings will help state meet targets for low-energy buildings.California has established ambitious goals to reduce energy consumption in buildings, including a policy goal for all new residential buildings to be zero net energy (ZNE) by 2020. Now the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has launched two projects to help the state... Read more

The knowledge and expertise of a seasoned energy efficiency professional has been packed into a high-tech suitcase.The Sensor Suitcase is a portable case that contains easy-to-use sensors and other equipment that make it possible for anyone to identify energy-saving opportunities in small commercial buildings. The automated and reusable system combines hardware and software in one package so its... Read more

Berkeley Lab finds that the choice of pavement material can significantly impact carbon emissions, creates decision tool for cities to useCool pavements can help keep cities cool, right? Yes, but according to new research from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), many reflective pavements have some unexpected drawbacks relative to conventional pavements...

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...

Researchers from the United States and Brazil have developed a new device that can reduce energy losses in buildings by measuring and assessing the energy performance of windows without removing them from their site. The Portable Window Energy Meter, still in prototype stage, was developed by researchers from Lawrence Berkeley National Laboratory (LBNL) and from Brazil’s Federal University of... Read more

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... Read more

Two projects within the Energy Technologies Area won honors at the 2016 R&D 100 Awards, an international science and technology competition.
