Climate change highlights the inadequacy of buildings in relation to local climate. Several studies on thermo-energy performance have been conducted, but there is still a gap in studying the influence of moisture on thermal comfort within buildings. In this context, a computational investigation was developed, considering two numerical modeling alternatives, Conduction Transfer Function (CTF) and Combined Heat And Moisture Transfer Model (HAMT), in the EnergyPlus program. To complement the study, experimental tests were conducted aiming to calibrate and validate the numerical results. The CTF model presented a greater internal thermal amplitude and divergences in relation to the experimentally measured values, indicating an overestimation of the internal temperature. On the other hand, the HAMT models obtained results closer to the experimental measurements, highlighting the importance of considering moisture in computational modeling.
