Phase Change Materials (PCM) has the capacity to store or release thermal energy through temperature fluctuations, which stabilize the internal temperature and improve the energy efficiency of buildings. However, problems dealing with thermal comfort in naturally ventilated environments in Brazil are still incipient. Thus, this article aims to analyze the thermal performance of a housing social interest incorporated with PCMs of by means computational simulation using the EnergyPlus software, in two Brazilian cities (Brasília-DF and Santa Maria-RS). We analyzed the results by the frequency of occurrence of hours of internal temperature in discomfort, to determine the most appropriate PCM for each climatic context, and season. The results obtained were satisfactory for both cities, and in the city of Brasília, PCM 25 presented 95% within the designated/established limits for comfort. In Santa Maria, in the periods of greatest discomfort for heat, PCM 25 proved to be more suitable, in discomfort for cold PCM 22 obtained better results.
