Abstract

Earthen materials might be a solution for energy issues being faced in construction, given their abilities to buffer moisture and improve indoor air quality while keeping the internal temperature relatively stable. However, their impact on the global energy performance of the buildings remains unclear. Our study aims at quantifying the effects of heat and mass transports, and phase changes occurring within the pores, on the hygrothermal behavior of earthen materials. To achieve this, a coupled hygrothermal model is derived. The relevancy of a certain simplifying assumption, i.e. neglecting the effects of mass vapor variation, is assessed through the analysis of the accuracy of the modeling, studied by numerical simulations on COMSOL Multiphysics®.
