Abstract :
[en] Materials with high moisture exchange capacity may have a strong impact on indoor
climate conditions as well as building energy performance. Crop-based materials, characterized
by their high porosity and hygroscopicity, belong to this category. Modeling
their hygrothermal behavior accurately is thus particularly relevant for appropriate
building design. A COMSOL Multiphysics transient heat air and moisture model is developed
in this article to simulate moisture exchange between a lime–hemp concrete block
and surrounding air during a Moisture Buffer Value evaluation test. Results are then
compared with the validated heat air and moisture software using performance criteria
showing a slight preference for both moisture exchanges and latent heat effect characterization.
It offers yet additional advantages in terms of flexibility and transparency as
well as further evolution potential.
