AbstractThis paper demonstrates the application of an advanced hygrothermal modelling tool for the moisture management design of the exterior building envelope. The exterior wall system considered in this study is a wood-frame stucco wall. The hygrothermal modelling tool used for this purpose is called hygIRC. The moisture management performance of the wall assembly is assessed at two Canadian geographic locations (Ottawa and Vancouver). The moisture response of the wood-frame stucco wall is analysed using a novel moisture response indicator called RHT index. The results from this study indicate that optimum vapour diffusion strategy in a wood-frame stucco wall can be determined if well defined input parameters such as construction details, material properties and boundary conditions are available.
