This research work consisted in making a comparative study of the thermal comfort of four materials types used in the construction of a building. A simulation of the building with the various materials on the KoZiBu software in reference and optimized situation was carried out. A study on the sensitive and air-conditioning loads as well as the curves of temperatures on a building of type F2 in situation of reference and in optimized situation was made on the one hand and the other hand a study on the same building without air-conditioning in reference and optimized situation. Finally, the analysis of the results favorizes the choice of the material having the best thermal comfort. The conclusions of these works show that the material that can give the best comfort and the most economics in terms of energy is the adobe which offers temperatures (301.40K or 28.40°C) and a good indoor thermal environment
compared to BLT (blocks of cut laterite), BTC (blocks of compressed earth) and cinder block. Dwellings built with earthen materials offer a better indoor thermal environment than those built with modern construction materials, which are used more and more in the construction of houses in Burkina Faso.
