It is of great significance to consider the problems of mold and mildew growth and condensation when designing walls in hot and humid climate region. In this paper, analytic hierarchy process (AHP) method was used to obtain the optimal wall structure. Taking a typical city in hot and humid climate region, Nanchang, as an example, the advantages and disadvantages of the four typical walls including brick wall, aerated concrete wall, plasterboard–fiberglass–brick wall and new-type wooden structure were ranked using AHP method. The weight coefficients of the four typical walls were 0.0573, 0.4215, 0.1489, and 0.3723, respectively. The results indicate that the aerated concrete wall has the best comprehensive performance among the four kinds of walls in hot and humid climate region.
