Today, the Center for Sustainable Research (CSBR), in conjunction with the Lawrence Berkeley National Laboratory (LBNL), the Alliance to Save Energy and the U.S. Department of Energy, officially launched www.CommercialWindows.org – a state-of-the-art website that provides critical information and performance data on the energy efficiency, interior environment, and technical considerations that influence commercial window design decisions. According to LBNL research, it is estimated that windows are responsible for 39% of commercial heating energy use and 28% of commercial cooling energy use – almost 1.5% of all total U.S. energy consumed. CommercialWindows.org features a number of comprehensive resources including a first-of-its-kind Façade Design Tool – an interactive, online tool that allows users to choose, early in the design process, various…
