The present study introduces a framework for integrating building information modelling (BIM) to building energy modelling (BEM) using labelled property graphs (LPG) and the Modelica simulation environment. The proposed methodology leverages graphs to effectively represent space boundarytopologyinformation.Graphsexcelatmodellingrelationships,enablingefficientqueries, intuitivevisualizationsandeasiererrordetectioninBIMmodels.Graph-basedoperationsareapplied to adapt the model for energy modelling. Additional steps including IFC validation, active systems and building operation parameters parsing, zoning process, and Modelica dynamic energy model generationarethoroughlydiscussed,providingvaluableinsights.Performance-wise,theframework showed promising results, achieving acceptable parsing times of only a few seconds. A case study of a multistory building in France demonstrated the framework’s effectiveness and functionality. ThemethodologystreamlinesthetraditionallycomplexBIM-to-BEMworkflow,ensuringrobustdata mappingandaccurateenergysimulations,andofferingpracticalguidelinesforfutureapplications.
