I am having problems about exporting gbXML file from Revit Architecture 2013.
I have assighed materials for the windows, doors and walls in Revit 2013. After I export it as gbXML file, I find that in the gbXMl file, the doors and walls' materials are well delivered, while the materials for windows are not. I can not see the thermal and physical properties in gbXML. All what gbXML file has is "WindowType id="GSP4R"".
My purpose is use the gbXML file to do energy analysis using Energy Plus, but since the windows' materials are missing, how could I do the energy performence analysis ?
An opening of the opening type “OperableWindow” does not have a constructionidref associated. It has a windowtypeidref. The WindowType contains information about U-value, SolarHeatGainCoeff and Transmittance. For more info please see http://wikihelp.autodesk.com/Revit/enu/2013/Help/0
