This dissertation studies the thermal performance of materials in a vertical facade building in the city of Belém - PA, Brazil. This work aims to contribute to the study of the thermal performance and efficiency of materials used in residential buildings of the vertical envelopment, between opaque elements, two types of materials currently very used in construction were selected, painting and ceramic coating. It also studies the influence of the height of the building on its thermal performance and energy efficiency. The study was conducted with the use of computational modeling in EnergyPlus code that evaluates the thermal performance of the building, the influence of the height at the same energy efficiency. Compares the thermal performance of the two selected materials, it was found that the ceramic coating presented building with the average internal temperature of 0.42 ° C above the temperature at the building painted, hence less thermal performance. The influence of the height of the floor did not produce a significant variation in internal temperature, because its increase, small decrease occurred in the internal temperature with thermal gradient of about -0.07 º C / m due to the wind speed is greater when more higher the pavement. It is also considered for this study as passive natural ventilation strategy for the building under study, according to the analysis of Bioclimatic chart Givoni contribute positively to the condition of the internal temperature and humidity, and consequently the user.
