The Federal Government’ Program Proinfância is based on the construction of a standardized design with a country-wide distribution. It is applied in all the eight different bioclimatic zones described by the ABNT NBR 15220-3 (ABNT, 2005). Standardized designs can overlook some aspects concerning the local climate, harming the building’s thermal performance, and reducing thermal comfort levels. When applied in buildings, Phase Change Materials (PCMs) show potential to increase thermal comfort in a passive way. This paper has the objective to evaluate the impact of the application of different types of PCMs within a standardized design of a public preschool from the Proinfância program, located in the bioclimatic zone 3. Computational simulations considering the hysteresis of the material were performed using the software EnergyPlus, and their results were analyzed according to the Adaptative Method from ASHRAE 55. Reductions of days in thermal discomfort conditions were perceived during the reference year, besides, the improvement of the average hourly operative temperature during summer and winter design days, thus, showing the capacity from the PCMs to increase the thermal comfort levels and, potentially, decrease energy consumption when air conditioning the building.
