The analysis of the thermal and hygrothermal behavior of existing wall assemblies allows for determining the temperature index, dew point, and condensation risks of envelope details. 

These analyses are very useful in the context of renovations, rehabilitations, and restorations of heritage buildings and help to better understand the behavior of the envelope in the context of expertise or during the conceptual phase of a project. The analyses are conducted by monitoring the walls using hygrothermal probes and WUFI PRO numerical simulations.
