This web was developed with support from the U.S. Department of Energy's Windows and Glazing Research Program within the Energy Efficiency and Renewable Energy Building Technologies Program. In partnership with the building industry, the U.S. Department of Energy supports a range of research, development, and demonstration programs, as well as education and market transformation projects, designed to accelerate the introduction and use of new energy-saving building technologies.

This web site was jointly developed between the Center for Sustainable Building Research (CSBR) at the University of Minnesota and the Windows and Daylighting Group at Lawrence Berkeley National Laboratory (LBNL), with support from the Alliance to Save Energy (ASE).
