Hygrothermal simulation incorporates transient heat and moisture transport in 1D and 2D wall assemblies. There is a need to understand how hygrothermal analysis can play a role in buildings designed to be moisture resilient. This paper investigates the hygrothermal effects on two different wall structures using different distributions of input parameters and two different weather scenarios. Results show that the differences in weather and distribution of the parameters have a limited effect on the sensitivity of parameters, but have a large impact on the uncertainty of the outcomes. A normal distribution of parameter means and an accurate weather scenario will improve the accuracy of the simulation, but might not be necessary if only the sensitivity of the parameters is of concern.
