Abstract

In order to solve the problem of building energy consumption, the hygroscopicity, thermal conductivity and transfer properties of composite polystyrene particle thermal insulation mortar are analyzed. According to the commonly used external thermal insulation structure and its thermophysical characteristics in hot summer and cold winter zone, the test is carried out. The thermal conductivity function is applied to the simplified model of DeST thermal environment simulation. The variation of heat and moisture transfer to building energy consumption is analyzed. The results show that the energy consumption of simulated buildings can reach 13.25% of the annual electricity consumption of building heating. Therefore, the heat and moisture transfer characteristics of materials affect the thermal conductivity and thermal insulation performance of building envelope. It is an effective way to decrease the building energy consumption by using the thermal conductivity coefficient of various materials as a measure.
