This paper aims to compare the percentage of occupied hours in thermal comfort (PHOCt) in an under construction naturally ventilated building in the Campus of the Federal University of Minas Gerais (UFMG) obtained by an EnergyPlus simulation and by a metamodel tool developed by Rackes et al. The building has 5 floors with a total area of 2678 m². PHOCt was obtained considering the adaptive comfort model for naturally conditioned environments proposed by ASHRAE 55-2013 in both cases. To use the metamodel it was necessary to adequate the following input parameters: 1) building maximum depth, 2) maximum floor to floor height and 3) maximum room power density of the occupied spaces to fit them within the range of the metamodel. Although such adjustments had to be made so the metamodel could be used to evaluate the thermal comfort it is considered that the proposed tool presented close PHOCt estimations both for INMET and TRY weather files when compared to simulations. Results found in metamodel were of 89% and 71% of occupied hours in comfort while the results obtained by EnergyPlus were of 92% and 77% for each weather file, the tool presenting a huge time saving when compared to simulation.
