Tungsten oxide smart window has excellent energy saving effect. According to statistics, if such new type of smart glass is used in glass curtain wall, it can reduce the operating cost of the building by 20%, including reducing its peak demand for electricity by 24%, reducing the load on the HVAC system by 25%, and reducing the lighting cost by 60%.

Experts say that this kind of smart window adopts electrochromic technology. They also said that electrochromic technology provides a new solution for energy saving in modern buildings, which can adjust the visible light transmittance of glass and solar radiation energy. S.Selkowitz, senior consultant for building science at Lawrence Berkeley National Laboratory, pointed out that "electrochromic technology is the most promising dimming technology in building applications." Tungsten trioxide is one of the most studied electrochromic materials due to its excellent electrochromic properties and electrochemical stability.
