ABSTRACT={The objective of this work is to improve knowledge on the thermo-physical characterization of building walls by comparing three numerical methods on an experimental masonry brick wall. The approach consist in a parametric identification of the thermophysical properties of the considered wall (namely the thermal conductivity λ and the thermal capacity ρ.cp), by comparing and minimizing the difference between the results of the experimental tests and those resulting from the numerical model. The experimental device consists of a controlled atmosphere thermal box crossed by a thermostatic bath radiator placed on the side opposite the wall. The experimental wall is a solid brick wall (6 cm × 11 cm × 22 cm) with mortar joints with a total thickness of 34 cm. It constitutes one of the four lateral faces of the box. Three different methods were examined: the analytical method using the heat transfer matrix, the finite element method using COMSOL® multiphysics software, and the Air node zone model method using the Type 56 of the TRNSYS® software. The results obtained were satisfactory for λ (0.914, 0.935, and 0.884 W.m-1.K-1 and for ρ.cp (1091445, 1057100, and 1095500 J/(m3.K)) for the three investigated methods.}}
