[en] Hygroscopic building materials can affect the indoor air by exchanging moisture with it and
buffering the ambient humidity variations. The Nordtest protocol and the concomitant
Moisture Buffer Value (MBV) parameter definition has been one of the first attempt to characterize this moisture regulation performance. This paper present an attempt to confront this well-established experimental protocol with a mathematical model implemented in the Comsol multiphysics solver. The power of the simulation will be showed with a good correlation between the modelling and the experimental phase for the MBV determination of a lime-hemp concrete bloc.
