To study the energy-saving effects of different enclosure structure, typical single residential buildings in the Wenzhou area selected as the research objects, and simulation tests were carried out in the same environment and the same period and analyzed the simulation results. The results show that in terms of walls, the best energy-saving effect type for the internal surface temperature of the wall is ceramsite concrete composite blocks, and the best energy-saving effect type for indoor temperature is non-clay sintered thermal insulation blocks, and the best energy-saving effect for indoor and outdoor temperature differences is foam concrete block; in terms of roof, the best energy-saving effect type of plant height is plant height 0.1m and plant height 0.5m; the best energy-saving effect type of leaf area index is leaf area index 0.3 and leaf area index 1.0; the best energy-saving effect type for leaf reflectance is leaf reflectance 0.85; the best energy-saving effect type for roughness is smooth and very rough; the best energy-saving effect type for thickness is 0.1m and 0.051m; the best energy-saving effect type of electrical conductivity is soil electrical conductivity 0.7 and soil electrical conductivity 0.4; the best energy-saving effect type of soil specific heat is soil specific heat 501J/(kg·℃) and soil specific heat 1500J/(kg·℃); the best energy-saving effect type of soil density is 2000kg/m3 of soil density
