Abstract：This study employs WINDOW7 software to investigate the impact of louver solar reflectance and louver angle on the solar heat gain coefficient(SHGC)of electrically controlled built-in louver insulating glass and magnetically controlled built-in louver insulating glass with three panes and two cavities.The results indicate that with increasing louver angle and higher louver solar reflectance,the SHGC of both electrically controlled and magnetically controlled built-in louver insulating glass decreases.The minimum SHGC for electrically controlled built-in louver insulating glass is 0.108,meeting the requirements of the GB/T 51350-2019"Technical Standard for Nearly Zero Energy Buildings",which specifies a summer SHGC≤0.15.When the electric built-in louver insulating glass is used in near-zero energy consumption buildings,silver paint louvers or heat reflective paint louvers can be selected,and the solar heat gain coefficient can meet the application requirements of near-zero energy consumption buildings with high shielding blinds.
