Building quality through hygrothermal simulation

Until just a few years ago, so-called dew point methods were the standard tools for evaluating the moisture balance of building components. However, they permit only a non-transient, i.e. highly simplified, assessment of the risk of condensation in winter. It doesn’t account for such factors as building moisture, driving rain, rising damp, hygroscopic moisture or summer condensation. Hygrothermal simulation, in contrast, permits a realistic simulation of the transient heat and moisture conditions subject to the measured outdoor climate and actual use, and includes all of the above-mentioned effects. WUFI® Pro thus allows a building component assessment from a moisture standpoint for any desired uses and climate boundary conditions – not just throughout the course of a year, but also long term over the lifetime of the building.
