Quality assessment of HAM-models to predict the hygrothermal response of building components

In this study, a comprehensive and stepwise validation of numerical Heat-, Air-, and Moisture-models will be performed. The main focus is on the prediction of the hygrothermal response of building components by comparing current available numerical models, and their implementation of material properties, boundary conditions, and driving factors. The research will start from simple and well-controlled lab experiments to in-situ measurements on actual building components. The datasets obtained from these experiments on different scales, complexity and conditions (from controlled lab conditions to real climate conditions) will be used for verification. Sensitivity studies of the influencing parameters and their impacts on the models will be also performed. Confronting numerical simulations with measured data sets of different complexity will result in guidelines for numerical modelling of heat, air and moisture transfer in building components.
