For the past 40 years, Lawrence Berkeley National Lab (LBNL) has been partnered with the window industry to help save American consumers money in energy costs by pioneering new energy-efficient windows, design tools, and window-rating systems.
The lab worked closely with window manufacturers and the building industry to develop, produce, validate, and deploy energy-saving low-emissivity or "low-E" coatings. Today more than 50% of window sales in... Read More
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... Read More
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... 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 liberal arts school in Northfield, Minnesota. He had... Read More
