This document discusses about Electrochromic windows, which can block the glare of the sun or provide instant privacy with the flip of a switch. Electrochromic windows are part of a new generation of technologies called switchable glazing-or "smart" windows-which change the light transmittance, transparency, or shading of windows in response to an environmental signal. Electrochromic windows change from transparent to opaque or shaded by an electric signal. Potential uses for electrochromic technology include privacy, daylighting control, and solar control in windows and skylights, making traditional window shades and blinds obsolete.
