For large-scale and high-end building projects, building performance simulation software is frequently used for purposes other than energy analysis. These programs typically run separately from BIM authoring tools and use their own 3D building models to execute daylighting, airflow, smoke/fire, egress and acoustic simulations.
Analysis programs handle building geometry data obtained from ARCHICAD differently, depending on their calculation method and available functions. Therefore, when exporting building geometry data to these softwares, users should export only the relevant parts of the ARCHICAD model.
The file format of the exported data also depends on the 3rd party programs. It is usually either IFC or gbXML, but DWG and DXF are also common. Some of these applications offer a dedicated IFC translator or ARCHICAD-specific plug-in application, which extracts the data required by their software from the ARCHICAD building model.
Since building performance experts typically produce 2D documentation as opposed to modifying the BIM model, the import of performance results from external applications into the ARCHICAD environment is not supported.
