Abstract

Phase Change Materials (PCMs) potentially increase the thermal inertia of environments when the adoption of heavy materials with high thermal capacity is restricted. Additionally, their use can promote thermal delay and damping and enhance the thermal comfort of users. This article aims to investigate the monthly influence of PCMs in internal walls of an office typology. The results were obtained from thermo-energetic simulation in EnergyPlus, using a theoretical office environment of approximately 50m², naturally ventilated. The PCMs evaluated are marketed by Rubitherm and have phase change temperatures between 18 and 35°C. The impact of each PCM on the monthly comfort levels of users was analyzed in six cities across the eight Brazilian Bioclimatic Zones (BZs). The results indicated a greater reduction in hours of thermal discomfort for the PCM with a phase change temperature of 21°C in cities within BZs 1 to 5. It was also concluded that the effect of the PCM becomes more significant when the average and minimum average monthly temperatures reach values close to or below 20°C.
