Because of the special physical shape and volume,the energy consumption of super high-rise buildings is larger than that of conventional buildings.Based on the concept of passive design priority and active design optimization,it is necessary to prioritize passive technical measures to reduce energy consumption.However,due to a series of problems such as the increase of wind speed and pressure caused by the height of super high-rise buildings and the high cost caused by the large volume,the safety,energy saving and economy of its application in super high-rise buildings are poor.Through case investigation and project summary,the collaborative optimization solution of window-wall ratio control is provided,as well as the glass curtain wall thermal parameter selection,sunshade design,ventilation design and daylighting design of super high-rise public building envelope.Through two green building cases,the optimization design process and new design ideas of the enclosure structure are specifically introduced,providing reference and guidance for the energy-saving optimization design of other super high-rise buildings in the future.
