Due to the great response to last year’s publication, the COMFORT consortium submitted a publication to this year’s e-Nova conference. This publication was accepted by the conference board and the final version was submitted this week. The publication will be presented on the conference in November 2021.

The publication describes the research conducted on the information exchange between Building Information Modelling (BIM) on one side and Building Energy Simulation (BES) and Computational Fluid Dynamics (CFD) simulations on the other side. The BIM to BES tests showed, that the automatised transfer of room information is possible, but the transfer of material parameters is currently not possible due to missing data interface points in the BES software. The BIM to CFS simulation data transfer is more complex than the BES case, requiring deep knowledge of the criteria for air space modelling and also a close collaboration of the BIM and simulation engineers. Furthermore, the inclusion of room usage descriptions currently not captured in BIM into future BIM software solutions was also investigated, so that this information is directly usable for simulations going forward.
