摘要：With the increasing global warming, more and more attention has been paid to the issue of energy conservation and environmental protection in the de- sign of building structures. In the process of con-struction structure design, the energy conservation and environmental protection performance of build- ing insulation materials is particularly important. In response to this problem, this paper analyzes the structure, advantages and disadvantages of different wall insulation systems, and the insulation perfor-mance of different insulation systems through fieldcomparison experiments. The heat transfer principle of building walls is analyzed, and the heat calcula- tion formulas of indoor air, wall insulation materials and external environment are established. The heat transfer coefficients of traditional building materials and green energy-saving and environmentally friendly thermal insulation materials are measuredthrough experiments. The average heat transfer co- efficient of traditional building materials is 0.086W/m2.K. and the average heat transfer coefficient of green energy-saving and environmentally friendly materials is lower than that of traditional buildingmaterials. Among them, the heat transfer coefficient of rock wool board is 0.028 W/m2.K. Field simula- tion experiments have proved that the thermal insu- lation effect of green energy-saving and environ- mentally friendly materials is higher than that of tra- ditional building materials.
