Nowadays,new building energy-saving wall materials are often used in residential buildings.Therefore,this study focuses on the characteristics of new building energy-saving materials,analyzes their application in residential buildings,and compares the energy consumption of different sizes of wall total thickness under different outdoor environmental temperatures.The experimental results show that under the condition of a total wall thickness of 105 mm,when the outdoor ambient temperature is 40℃,the cooling energy consumption of the air conditioning differs by 3.2℃,with the largest difference.The decreasing trend of the cooling energy consumption of the air conditioning is slowed down,and the energy-saving effect of the building is significantly reduced.When the outdoor environment is-30℃,the difference in heating energy consumption of air conditioning is 4.8℃,and the heating energy consumption shows a decreasing trend.It can be seen that significant energy-saving effects can be achieved in both high and low temperature environments,but the practical value of wall thickness exceeding 105 mm is not significant.
