Overview of Electrochromic Materials and Devices: Scope and Development Prospects

Today, the global energy consumption associated with heating, air conditioning (cooling) and lighting of buildings (which is about 40 %) can be significantly reduced through the use of chromogenic materials or the so-called "Smart Window" technology. Approximately 20-25 % of thermal energy can be saved by reducing heat loss through the windows, and 25-30 % of the electrical energy spent on lighting will be saved by using Smart Window technology instead of conventional windows, which are less energy-efficient in buildings.
