The reviewed data indicate that optimized curtain wall configurations—especially those integrating electrochromic glazing and BIPV modules—can achieve annual energy consumption reductions ranging from approximately 5% to 27%, depending on climate, control strategy, and façade. . The reviewed data indicate that optimized curtain wall configurations—especially those integrating electrochromic glazing and BIPV modules—can achieve annual energy consumption reductions ranging from approximately 5% to 27%, depending on climate, control strategy, and façade. . However, during summer time, intense solar radiation leads to significant indoor heat gain, which adversely affect thermal comfort and energy efficiency. The conventional air conditioning systems are typically equipped with a cooling capacity sufficient to maintain an indoor air temperature at the. . Solar control glass reduces heat gain by filtering infrared rays while maintaining high visible light transmission, making it ideal for energy-efficient curtain walls. Reflective glass minimizes glare and solar heat by reflecting sunlight with a metallic coating, enhancing privacy and aesthetic. . This review presents a comprehensive examination of curtain walls from an energy-engineering perspective, highlighting their structural typologies (Stick and Unitized), material configurations, and integration with smart technologies such as electrochromic glazing, parametric design algorithms, and. . By reducing energy consumption and optimizing building performance, curtain walls have become a preferred choice for general contractors and architects aiming to meet both functional and environmental goals. From their lightweight composition to their ability to regulate indoor climates, curtain. . Traditional glass curtain wall construction cannot meet the requirements of building energy-saving management, which is specifically manifested in high heat conduction and poor thermal insulation performance. This time, the construction technology of energy-saving building glass curtain wall is. . They now serve as active energy generators, thanks to advances in photovoltaic glass integrated into curtain walls. This innovation allows buildings to produce renewable energy while maintaining sleek, modern appearances. From commercial skyscrapers to institutional buildings, the use of.
