I'm able to export all Areas to IFC using Revit 2013 and the IFC Exporter V2.14 (found in Autodesk Exchange Apps). Using Revit 2014 and the newest IFC Exporter V3.6 (also from Autodesk Exchange Apps), I've been able to export only Gross Building Areas, not the Rentable Areas. Is the IFC Exporter for Revit 2014 more limited than the one for 2013, or am I doing something wrong?

To answer my own question: I found out, that the IFC exporter V3.6 only works with Revit URI. So I installed the Update Release 1, and now I can export all Areas.
Thank you for sharing the solution.
