The calculation of hygrothermal performance allows to get realistic results by describing all mechanisms of transport and accumulation of moisture and heat within building materials. In addition to heat conduction, it also makes it possible to model moisture transport both as vapour diffusion and water transport by capillarity. With regard to the interaction of building elements with climatic parameters, it is also possible to include all the factors required for a realistic calculation, modelling not only heat transfer by conduction and moisture transport by diffusion, but also effects such as driving rain, solar radiation or long-wave radiation. Furthermore, it is possible to model these effects on an hourly or even sub-hourly time scale. Both 1D stratigraphies and 2D building details can be modelled.

The simulations and calculations performed can also be integrated with experimental analyses. In particular, in our infrastructure Hygrothermal Testing Lab, we can measure all the physical parameters of materials required for modelling in hygrothermal software in dynamic mode. This gives manufacturers and companies the opportunity to have a specific evaluation of their materials and products.
