| Abstract | This paper describes the benchmarking exercise for the present hygrothermal model called 'hygIRC-C' against the hygIRC-2D model that was previously developed at NRC-IRC and test results of laboratory measurements of drying of four full-scale wall assemblies. The wall assemblies were representative of the North American wood frame construction. These walls were subjected to different exterior and interior conditions and varying initial moisture content of OSB sheathing board components. The present hygrothermal model was recently developed at NRC-IRC. This model solves the highly nonlinear and coupled Heat, Air and Moisture (HAM) transport equations. The results showed that the overall agreements between the present model and the hygIRC-2D model as well as the experimental measurements were reasonably good in terms of the shapes of the drying and drying rate curves. Additionally, the predicted average moisture content of the different wall assemblies over the test periods were in good agreement, all being within +5% of those measured. |
