Extension of the IFC4 schema for simulation applications

[DaJansenGit]

As part of the BIM2SIM research project our research group has investigated the existance of relevant information for thermal building simulation and HVAC simulation in IFC. We compiled the information in two Excel spreadsheets based on the current official release IFC4 ADD2 TC1.

Requirements_IFC_HVAC.xlsx Requirements_IFC_BPS.xlsx

Since the IFC schema is extremely complex, it is quite possible in individual cases that we have overlooked existing information. If this is the case, we ask for your indulgence. At some points in the tables, reference was made to the final report of the project. This is currently not yet publicly available, but we will link it here as soon as possible.

We would like to share and discuss this information in view of the development of further IFC versions. We hope that the results can help IFC to become even more widely used in the field of building and HVAC simulations.

Just wanted to ask if there are any opinions regarding the provided investigations, looking forward to your answer.
