BIM2SIM for Hydraulic-Focussed Energy Simulations – Automatic Generation of Pre Parametrized Simulation Models
David Jansen, Dominik Hering, Dirk Müller · 2023
The construction of energy-efficient buildings is one of the most important measures to reduce the impact of buildings on our environment.The dynamic simulation of the energy systems of these buildings can improve the design and performance and thus reduce the emissions that impact the environment.However, the process of creating models for dynamic simulations is time-consuming and error-prone.By using already existing digital models from the planning process the process of model generation can partially be automated.This paper presents the tool bim2sim and its underlying methodology for the application of automatic model generation for dynamic hydraulic energy system simulation with Modelica based in Building Information Modeling models with the open exchange format IFC.The tool is applied to the use case of an example energy system and a manual comparison modeling is performed for the energy system in Modelica.The comparison shows that automatic model generation saves a significant amount of time even for comparatively simple systems.
