• The fire smoke flow prediction software developed successfully was applied to simulate a simple building. The effect of different wall structures on the fire smoke flow properties were compared under the condition of same thermal resistance of external wall. Heat absorption of wall has a cooling effect on indoor air in fire process. Wall with external insulation has the most significant cooling effect on indoor air, and that with internal insulation has the weakest. The effect of intermediate insulation is close to external insulation and that of bilateral insulation close to internal insulation. Room temperature and smoke concentration of internal insulation are both higher markedly than of external insulation. The effect of intermediate insulation is close to external insulation and bilateral insulation close to internal insulation. External insulation added to the closure helps to cool indoor air in the fire process. Intermediate insulation should be chosen to add to the inner wall when needed because of the uncertainty of fire location.
