Electrochromic Windows

Research output: NRELFact Sheet

Abstract

The tint of electrochromic (EC) windows can be controlled on demand through an electric signal. The window can become darker to keep sunlight out, and clear to provide better views, illumination, and passive solar heat gain. This dynamic control allows EC windows to provide substantial energy savings to buildings, both by enabling solar gain when it is cold outside and blocking unwanted solar gain when it is hot. EC windows are commercially available in the U.S. from multiple manufacturers and have been installed in many buildings nationwide.
