Have you tried loading the IDD file explicitly before loading your IDF? For example:

IDF.setiddname(r"C:\\EnergyPlusV9-3-0_b\\Energy+.idd")

Have you tried loading the IDD file explicitly before loading your IDF? For example:

IDF.setiddname(r"C:\\EnergyPlusV9-3-0_b\\Energy+.idd") ``` from eppy import modeleditor from eppy.modeleditor import IDF

IDF.setiddname(r"C:\EnergyPlusV22-1-0\Energy+.idd") idf_file = IDF(r"C:\EnergyPlusV22-1-0\ExampleFiles\1ZoneUncontrolledAnnualOutputs.idf") ```
