OS reverse translator does not retain the spectral data type of glazing

edit

Here's a related question that might be helpful: https://unmethours.com/question/23474...

Thank you Mathew. This is not exactly the same problem. Here is what I did:

(1) I loaded an E+ idf and reverse translated the E+ idf to OS model and saved the OS model to new OSM idf. The opticalDataType of glazing objects in E+ idf were SpectralAverage but in the OS idf it is translated to Spectral. The opticalDataType is lost during reverse translation.

below is the C# binding code I used to load and reverse translate the E+ idf:

OpenStudio.OptionalIdfFile oIdfFile = OpenStudio.IdfFile.load( idfPath, new OpenStudio.IddFileType( "EnergyPlus" ) );
OpenStudio.IdfFile idfFile = oIdfFile.get();
// reverse translate the idf file to an OpenStudio model
OpenStudio.EnergyPlusReverseTranslator translator = new OpenStudio.EnergyPlusReverseTranslator();
OpenStudio.Model model = translator.translateWorkspace( new OpenStudio.Workspace( idfFile ) );

Just go to the material is the GUI and change it back to SpectralAverage. The reverse translator isn't fully featured and not a OS development priority.

Is your IDF a complete model or just objects from LBNL WINDOW or maybe another use case? If the former, you'll also completely lose the HVAC systems in reverse translation. Any reason not to simply work on the IDF (workspace) directly with the C# bindings?
