Resumo: Studies of energy use in buildings are complex and require interface of several fields of knowledge. In order to encompass the multidisciplinary field of information architecture, mechanical engineering, and behavioral phenomena of climatology, computer simulation stands out as one of the tools for assessing energy expenditure. Thus, in order to consolidate the use of a thermo-energetic simulation program in the process of labeling for energy efficiency in buildings in Brazil, the Technical Regulation for the Quality Level of Energy Efficiency in Commercial, Service and Public Buildings (RTQ-C), the PUC-PR in partnership with Eletrobras (Brazilian Electric Power Company), is working to improve the Domus program for the analysis of the requirements established by RTQ-C. Thus, the purpose of this paper is to analyze, by means of computer simulation, the Domus program usability through parametric simulations, comparing them with another internationally recognized program, the Energy Plus. In order to do it, we used a representative model of a small size office building with five floors, being divided into four prototype tests (monozone without window, monozone with window, multizone without window and multizone with window), which made possible simulating the parameters of internal temperature, degrees/hour and thermal gain of constructive components in the 8760 hours of a year. The results obtained in the analysis of indoor temperatures revealed that the two programs show good correlation, unlike the assessment done through the degrees/hour, in which differences occur mainly in monozone models. In the comparison of thermal gain of constructive components, many surfaces showed similar behavior between programs; but some, especially those in contact with another surface, showed different results.
