This can be reproduced with the attached IFC model and the script e1_simple_project_bps_teaser.py. I have just tested the export again on the current dev-branch of bim2sim. The code runs when the CheckIfc function is commented out. Because I don't have Dymola on this PC, everything from SimulateModelEBCPy onwards is also commented out. In BIMTEST3.zip you will find the output of Teaser. The area of the aggregated zone is too small by a factor of 10^6 and should actually be 43.71 m². The window areas, for example, are similar. In the IFC file, the length unit is stored as millimeters. The dimensions appear to be correct in the idf. However, the coordinates in BuildingSurface:Detailed are somewhat strange.
