WASHINGTON, DC ? The U.S. Department of Energy (DOE) today announced a next-generation residential and commercial window prototype. When widely implemented in the marketplace, the high-performance features of the prototype could save billions of dollars annually in energy costs. The new technologically advanced window concept is the result of collaboration between DOE's Lawrence Berkeley National Laboratory (LBNL) and SAGE Electrochromics, Inc. (Faribault, Minnesota).
