Interoperabilidade entre modelos BIM e Análises Energéticas: Desenvolvimento de ferramenta no Blender para integração de dados de modelos IFC com método simplificado de análise da INI-R

Abstract

The advancement of development of technologies aligned with building information modeling (Building Information Modeling - BIM) has allowed the creation of virtual construction models with integration of multidisciplinary data throughout the life cycle of a project. he interoperability between BIM software and energy analysis tools still has limitations, especially because they are still concentrated in workflows that involve software from the same manufacturer. This dependency presents a barrier to designers trying to incorporate these analyzes into the development of a design. In view of this, it is necessary to explore open-source software and open standard file formats, such as the Industry Foundation Class (IFC), to advance proposals for interoperability between BIM models and energy analysis. The Inmetro Normative Instruction for the Energy Efficiency Classification of Residential Buildings (INI-R) represents an effective and promising method for the energy assessment of residential constructions. The objective of this research is to develop and explore an efficient workflow that allows the integration between IFC models with the simplified method of energy analysis of INI-R, thus obtaining the prediction parameters as a result for an initial perception of the performance about the analyzed project. For that, a method was developed for the integration of BIM models, through the elaboration of a tool in the Blender software for the filling and extraction of relevant data from the IFC file and the organization of these data in the Excel spreadsheet model of the INI-R Interface. A case study was carried out for the application of the developed tool, by using IFC files exported from Autodesk Revit and Graphisoft ArchiCAD software, showing the viability and effectiveness of the proposed approach. To validate the results obtained, the spreadsheet was filled in manually in order to compare the results with the integration method by the developed tool. The results prove the efficiency and feasibility of integrating IFC models with the simplified INI-R analysis method. These analyzes carried out in the conceptual stages of the project provide support to designers, allowing the specification and exploration of design alternatives in which changes are less expensive, compared to more advanced stages of the executive design, construction or operation of a building.
