Hygrothermal simulation of drying performance of typical north american building envelope

Hygrothermal modeling of building envelope has received much attention and development in recent years; to increase its flexibility and accessibility is a consequential task. A powerful multi-physics simulation program, FEMLAB is applied to explore an efficient method of hygrothermal modeling. This paper presents a hygrothermal model and its application to analyze moisture behavior of typical North American building envelope systems. Comparison between simulation and experiment is made. It is shown that the model has satisfactory performance and great potential for further research purpose.
