There is currently 2 BIM format related to energy modeling : [https://www.gbxml.org/ gbXML] and IFC ([https://standards.buildingsmart.org/IFC/RELEASE/IFC4_1/FINAL/HTML/link/ifcrelspaceboundary2ndlevel.htm using IfcRelSpaceBoundary2ndLevel]) | There is currently 2 BIM format related to energy modeling : [https://www.gbxml.org/ gbXML] and IFC ([https://standards.buildingsmart.org/IFC/RELEASE/IFC4_1/FINAL/HTML/link/ifcrelspaceboundary2ndlevel.htm using IfcRelSpaceBoundary2ndLevel]) | ||
− | Most energy analysis software reads gbXML. Some read IFC. Generating geometry for gbXML and IfcRelSpaceBoundary is quite similar. Information contained in both format is different. | + | Most energy analysis software reads gbXML. Some read IFC. Generating geometry for gbXML and IfcRelSpaceBoundary is quite similar.

Overmodelled building often lead to error and/or uselessly complex computation. A energy model should be simple and contain only energy relevant information. | Overmodelled building often lead to error and/or uselessly complex computation.

* Rework an IFC coming from another authoring tool. This is probably the most efficient workflow currently. It allows you to enhance your model and fixes common known issues incoming from popular authoring software. | * Rework an IFC coming from another authoring tool.
