BIM/BES INTEROPERABILITY: A CASE STUDY BETWEEN REVIT®, DESIGNBUILDER®, IES-VE®, AND E-QUEST®

Abstract

Objective: This study proposes a BIM/BES interoperability test through a case study involving Revit® and three BES software programs: DesignBuilder®, IES-VE®, and e-Quest®. Theoretical Framework: For thermo-energy analyses, a recognized combination is the BIM (Building Information Modeling) / BES (Building Energy Simulation) pair. This requires data transfer from one software to another. To export the virtual model, it is necessary to generate the energy analytical model in BIM and use transfer protocols for BES software. Various studies have indicated failures in this process. Method: A case study was used to analyze the interoperability between the software programs, through a 58m² single-family residence. The geometric model was created with its dimensions and layers, input data such as location, thermal properties of materials, and usage data, generating the energy analytical model and exporting it to each BES software. Interoperability was tested based on data transfer analysis, establishing seven criteria. Results and Discussion: The results indicated failures in interoperability, as none of the software programs exported all the criteria correctly. The BES software with the best results was IES-VE®, with 70.90% of the criteria exported, followed by e-Quest® (65.45%) and DesignBuilder® (45.45%). Research Implications: The results of this study demonstrate that interoperability challenges limit the potential of the BIM/BES pair. Originality/Value: Despite studies on this topic, interoperability challenges remain, representing a gap to be filled.
