Abstract: Simulation of Heat, Air and Moisture (HAM) transfer in building envelope is a practice, which is becoming increasingly popular. This is due to the impact of moisture transfer on the energy performance of the envelope and indoor air quality as shown in the latest studies related to this subject. This article focuses on the study of the behaviour of a highly hygroscopic thermal insulating material which is wood fibre. The experimental investigation is achieved using an experimental facility, which reproduces wide range of hygrothermal solicitations in building. It has various physical measurements, which allows the understanding of hygrothermal phenomena and provides sufficient data to validate HAM models. The experimental results for isothermal conditions has been interpreted using a classical model for HAM transfer. The results highlighted heat and mass coupling effects, especially the contribution of latent heat, in the overall energy balance for different type of loading.
