und Modelica) und den Informationsanforderungen des ausgewählten Simulationsszenarios in den beiden UseCases BIM2SIM und SIM2BIM. Für die Modellübertragung wurden Wissensgraphen für die intermediäre Wissensrepräsentation verwendet. Dies ermöglicht die Anwendung von in der IT bereits entwickelten semantischen Technologien für die Übersetzung zwischen BIM und Simulation. Weiterhin bieten die Wissensgraphen Anknüfungspunkte für Anwendungsfälle die weit über die in dieser Arbeit untersuchten UseCases hinaus gehen.

The integration of system simulation into the design process for HVAC equipment contributes to more energy-efficient operation of buildings. A major hurdle in the application of simulation as a design tool is the effort involved in modelling. This work deals with the automated modelling based on BIM (Building Information Management) models in order to reduce this effort. Furthermore, the utilisation of simulation models that have been created through the generation of BIM models is considered. Tools for the bidirectional link between BIM and simulation models were created as part of the work. The considerations focus on the simulation format Modelica and the open BIM format IFC. The implemented tools are based on an assessment of the expressiveness of the selected formats (IFC and Modelica) and the information requirements of the selected simulation scenario in the two use cases BIM2SIM and SIM2BIM. Knowledge graphs were used as intermediate knowledge representation for the model transfer. This enables the application of semantic technologies already developed in IT for the translation between BIM and simulation. Additionally, the knowledge graphs provide starting points for use cases that go far beyond the use cases investigated in this thesis.
