This paper deals with validation of an enhanced mathematical model for description of coupled heat and moisture transport which is able to model ice forming processes. This phenomenon is usually neglected because of computational difficulties even if it has a significant influence on heat and moisture transport. For the sake of model validation, data gathered by means of semi-scale experiment was used, analyzing a hygrothermal performance of a real building assembly ? an external wall. The wall was exposed to dyna...

Computational modelling of hygrothermal performance of building materials has become very popular in recent decades as it is able to provide reliable results in a very short time. However, the accuracy of obtained results depends on various factors, the knowledge of material properties in particular. Even if many sophisticated experimental methods have been developed for that purpose, being able to provide reliable data, there is still one aspect which often remains ignored. According to the literature review, the...
