Smart glass has been around for a while, but not every client has the budget or innovative drive of the NREL RSF. Also, most smart glass blocks only the visible component of light, still letting the invisible IR component enter the space. A new smart glass has been developed that embeds a framework of electrically conducting nanocrystals in a glass substrate. This ‘nanocomposite’ blocks up to 90% of near-infrared light and 80% of visible light, and features three modes:
In addition to the standard bright and dark modes it features a “cool” one, which could help buildings save energy during hot days. It can switch between modes in just minutes—faster than any commercial electrochromic window material... - MIT Technology Review
A cheaper and more reliable manufacturing process makes this technology especially appealing for mainstream market integration, estimated for 2017.
