The International Energy Agencyâ€™s Energy in Buildings and Communities Programme (IEA-EBC) coordinates development of BPS in Modelica in the project "Computational Tools for Building and Community Energy Systems", also known as Annex 60.
Even with advanced BPS libraries at hand, developing BPS models and collecting required input data are time-consuming and error-prone processes, preventing practitioners from using BPS more extensively in standard planning processes.
Building Information Modelling (BIM) is a well established technology to model and manage the digital representation of a building over its entire lifecycle. Reusing existing Building Information Models (BIM) as basis for Building Performance Simulation (BPS) has the potential to make BPS model development and subsequent simulation easier, faster and more reliable.
Activity 1.3 of the Annex 60 project is working on an open-source tool-chain that can semi-automatically generate code for BPS Modelica models from a BIM data source.
In this contribution, we give an overview over the tool-chain and the involved steps as well as a more detailed description of those parts of the tool-chain that are used for controlling the workflow and for the actual generation of Modelica source code files.
