Abstract: 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.
