Current moisture guidelines for building envelopes employ specification standards, which specify the types and the details of building assemblies. However, required performances to avoid moisture damages within building envelopes should be clarified in terms of performance standards. Taking these back grounds into account, we already proposed a framework of a practical design method based on the frequency of relative humidity within wooden wall assemblies in the previous paper of this research. In this paper, a regression model to predict the excess frequency of the relative humidity is proposed by statistical analysis of simulation results of a one-dimensional HAM model. Moisture resistance ratio that is one of the design parameters to determine wall specifications can be derived from the model. Accuracy of the model was examined in comparison with the precise values regarding the excess frequency. Furthermore relation between the moisture resistance ratios and climate conditions was discussed in terms of regional classification based on the required performances.
