AB - The current analysis method of thermal insulation performance of building  envelope neglects the optimization of temperature control parameters, which  leads to poor thermal insulation performance, low thermal insulation rate  and weak convincing results. Therefore, a finite element analysis method  for the thermal insulation performance of high rise building envelope is  proposed. Compton backscattering technique is introduced to analyze the  influence of the scattering intensity and the ratio of window width on the  heat transfer coefficient of the enclosure. Based on the objective function,  the thermal performance parameters of retaining wall are calculated and  fused. An adaptive iterative optimization method is used to control the  thermal performance of the enclosure using the thermal performance  parameters of the enclosure. Through the Compton backscatter detection  technology, the decision variables of energy consumption of the thermal  insulation materials are obtained, and the temperature control parameters of  the walls are optimized. The finite element model of enclosure structure is  established by using finite element software. The results of finite element  model experiments show that the proposed method has ideal heat preservation  rate and energy consumption. Compared with the traditional method, the  proposed method can keep the preset temperature.
