Owing to an increase in the air tightness of recent buildings, the natural ventilation rate was significantl lowered and the removal of accumulated moisture became difficult in these buildings. The hygrotherma performance of these buildings should be carefully considered to provide comfortable indoor environment b removing the moisture condensation risk and the mold growth potential. In this study, hygrothermal performanc of two selected wall structures was investigated based on WUFI simulation program. The results displayed tha the indoor temperature had impact on the moisture accumulation in the insulation layer for both modeled walls showing that lower indoor temperature resulted in higher moisture accumulation, especially in the wood fram structure. Also, the yearly moisture accumulation profile exhibited a downward shift throughout the year b adding a vapour retarder with a lower sd-value. In addition, both of the two walls have condensation risk i winter, due to low temperature level. The wood frame structure has a bigger fluctuation and higher condensatio risk than the concrete structure.
