In this paper, we present our main results of the post occupancy evaluation of thermal comfort of two primary schools constructed following the same plane, situated in two different climate zones. The first stage of the work consisted on measurements using meteorological equipments. These measurements are used to quantify the physical parameters of the thermal atmosphere, such as temperature, rate of relative humidity and wind speed prevailing inside classrooms. The second step aims to support the results of the first stage; and it is a psychological investigation using inquiry with users.
