New High-Efficiency Window
Posted By: Jamie  on 12/21/2006
WASHINGTON, DC – The U.S. Department of Energy (DOE) announced a next-generation residential and commercial window prototype. This prototype incorporates dynamic electrochromic glass (SageGlass®) that can be electrically controlled to change from clear to dark.  The prototype also includes other technology innovations, such as low emissivity (Low E) glass coatings, an unsealed internal plastic triple pane, krypton gas and an insulating frame.  This is the first time that all of these technologies have been optimized in an integrated fashion.  Continued research and development (R&D) lower the cost of advanced energy-saving glass and will allow today’s prototypes to be incorporated into affordable, mass produced products from many window suppliers.  Consumers can currently purchase dual pane dynamic windows from SAGE Electrochromics.

DOE’s long-term window development goal is to produce windows that are as energy efficient as today’s walls.  By incorporating advanced technologies, windows can actually become a net-energy provider for homes.  Advances in window technology will also ensure that their solar heat gain is very low in summer, which could potentially mitigate electricity demand.
