This research analyzed the influence of heat conduction and thermal radiation on the wall structure, discussing the differences within composite laminar wall and single layer construction. Based on the analysis results, it is estimated that the effectivity of overall heat flow field in external walls of existing community buildings and provide suggestions for the planning of urban renewal operations. The research results show that the wall insulation of steel-aluminum composite laminates is excellent, and the thermal insulation performance is up to 1.6 times that of the general steel materials. The heat flow enters from the roof plate and is output by the slab plate; however, much less horizontal temperature gradient is observed in the vertical walls. Therefore, in the tropical climate, the general roof of the building in the solar radiation state, the insulation performance should be more stringent requirements than the vertical wall. The architectural design code should focus on roof insulation and ventilation, enhanced the efficiency of relative construction standards.
