smart glass

Smart glass or switchable glass (also smartwindows or switchable window in those applications) is a glass or glazing whose light transmission properties are altered when voltage, light, or heat is applied. In general, the glass changes from transparent to translucent and vice versa, changing from letting light pass through to blocking some (orall) wave lengths of lightand vice versa.

Smart glass technologies include electrochromic, photochromic, thermochromic, suspended-particle, microblind, and polymer-dispersed liquid-crystaldevices.

When installed in the envelope of buildings, smart glass creates climate adaptive buildingshells.
