Large numbers of studies have shown an association between living in homes with signs of 'dampness', and incidence and prevalence of airway diseases among children and adults. Damp house have possibility to encourage microbial growth which can increase the risk of adverse health effect and cause the deterioration of indoor air quality. In order to prevent health damage for residents in damp houses, the development of precise prediction method for indoor humidity and microbial condition in design stage is needed. This research focuses on the hygrothermal transport in residensial bathroom. Indoor environment in bathroom becomes high humidity during and after having a bath, and dew condensation on cold wall surfaces is one of the problems in view point of deterioration and disfigurement of building materials. We reports the procedure and the results of coupled numerical simlation incorporated with flow field analaysis and temerature/ humidity distribution in bathroom space and also reports the prediction mehod of microbial contamination in damp houses. Furthermore, microorganism growth on wall surfaces under high humidity environment is also confirmed to take countermeasures against contamination.
