Smart windows (SW) feature reversible color changes, utilizing voltage (~2V) to enable manual or automatic regulation of sunlight transmittance through the windows. When applied to smart residential buildings, they provide the benefits of thermal insulation, energy conservation, and carbon reduction. Currently, companies capable of mass production are constrained by high manufacturing costs, which prevents market acceptance from increasing. Other types of smart windows are mostly liquid crystal products, which lack weather resistance and cannot yet be applied to exterior windows or curtain wall glass. Our team utilizes laminated glass manufacturing technology to develop low-cost, highly weather-resistant, and highly heat-insulating smart glass, effectively simplifying construction methods, saving time, reducing costs, and increasing the adoption rate of smart windows in green buildings.
