THERMAL INSULATION PERFORMANCE ANALYSIS OF HIGH RISE BUILDING ENVELOPE BASED ON FINITE ELEMENT ANALYSIS

ABSTRACT
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.
