Abstract

The dynamic property is the essential property of heat transfer in the envelope, and the dynamic thermal response mechanism is the embodiment of its dynamic operation law. The dynamic behavior of the envelope structure in summer is more typical than that in winter. Therefore, this paper studies the dynamic mechanism and application of of thermal isolation building envelope. By investigating the dynamic thermal response mechanism of the building envelope, this paper propose a novel metric called G_max which comprehensively evaluates the thermal performance of the envelope structure under diverse operational conditions. Chongqing, which is hot in summer and cold in winter, is taken as an example for simulation analysis. The results show that when G_max<60 W/m², the dynamic thermal response performance can be effectively improved by increasing the maximum heat isolation G_max of the wall. When Gmax=60~90 W/m², the dynamic thermal response performance can be less improved by increasing G_max>90 W/m², the dynamic thermal response performance of the wall will be reduced by increasing G_max.
