INTEROPERABILIDADE ENTRE SOFTWARES BIM E BEM PARA FINS DE GERAÇÃO DE MODELOS PARA SIMULAÇÃO TERMOENERGÉTICA

Abstract

Interoperability between BIM (Building Information Modeling) and BEM (Building Energy Modeling) software is required to perform thermoenergetic simulation using EnergyPlus software. In this regard, this article presents a comparison between energy models (BEM) developed by BIM modeling software, with the main goal of identifying procedures that result in more reliable models to be used in simulations. In order to develop this work, 4 methodological steps were defined: investigation and study of the softwares to be used (BIM and BEM); development of a reference model (through Euclid plug-in in SketchUp ); development of BIM/BEM models (with the use of Autodesk Revit /OpenStudio ); and, finally, comparison between BIM/BEM models and reference model. The results of this process allowed us to evaluate which aspects have the greatest influence when creating better BEM models. At the end of this work, it was concluded that models generated in Autodesk Revit still do not have a satisfying level of interoperability and produce flaws in the building’s geometry. Also, it was concluded that, for both Euclid /SketchUp and Autodesk Revit , the energy analysis models must be predicted during architectural conception of projects, otherwise, adapting existing models would make the process laborious and would produce many errors.
