The material was chosen in order to satisfy the RE2020 requirements regarding the carbon footprint reduction of building materials. The wall is tested and subjected to wetting/drying cycles by T/RH variations with/without solar radiations and rainfall. The last two climatic conditions are real and rarely taken into account in the study of hygrothermal behavior. Therefore, an experimental set-up was designed and a numerical model was proposed. The numerical and experimental results were compared for the both tests. The results obtained highlighted the ability of the numerical model to reproduce the hygrothermal behavior of the wall. For Test 1, the RMSE value is about 0.24 °C, 4.78 percent and 2.28 W.m?2 for T, RH and thermal flux, respectively. Whereas, it is about 0.23 °C, 3.47 percent and 7.79 W.m?2 for Test 2. The impact of rainfall is 3.33 time more than the test without rain for a material with porosity about 14.18 percent . As for drying, the solar radiations has an important intensity of about 820 W.m?2 and induces a significant heat flux at the external border.
