摘　　要：当前通常只选用外墙外保温方式或外墙自保温体系实现超高层建筑节能,效果不佳。为此,提出一种外墙外保温与自保温体系相结合和的超高层建筑节能方法。选择实际工程中某超高层建筑开间作为外墙保温建筑节能的研究对象,对当前热桥节能相关资料进行总结分析,完成热桥的构造。建立外墙外保温体系,确定外墙黏土砖厚度、墙体热桥和窗户种类以及EPS板保温层厚度。将指标评价方法和对比评价方法结合在一起,对外墙外保温与自保温体系相结合的超高层建筑节能方法节能性进行评价。将独立外墙外保温方法和独立外墙自保温方法作为对比进行动态计算与比较,验证所提方法的节能性。结果表明,所提方法节能性高。At present,the energy saving of super high-rise buildings is usually achieved only by external wall external insulation or external wall self insulation system.For this reason,a method of energy saving for super high-rise buildings is put forward,which is combined with external thermal insulation and self insulation system.A super high rise building in the actual project is selected as the research object of energy saving of the external wall insulation building,and the energy saving data of the current heat bridge is summarized and analyzed,and the construction of the heat bridge is completed.An external thermal insulation system for external walls is established to determine the thickness of the external wall clay bricks,the types of thermal bridges and windows,and the thickness of the insulation layer of the EPS board.Combining the index evaluation method with the contrast evaluation method,the energy conservation of the super high rise building is evaluated by the combination of external wall insulation and self insulation system.The independent external thermal insulation method and independent external wall self insulation method are compared and compared dynamically to verify the energy saving of the proposed method.The results show that the proposed method has high energy saving.
