4 years ago quick response here before looking into the idd file.
- upgrade to the latest eppy version.
- it will give you an error when you try to read your
idffile- the
iddfile has only 50 objects - the error message will tell you how to update your
iddfile to add more objects - (make sure you keep a backup of your original
idd)
- the
- once you update your
idd, it should work - continue to look for error messages
- there may be other objects that need update in the
iddfile
- there may be other objects that need update in the
eppy depends on the idd file for everything it does
eppy 0.5.46, python 37, energyplus v9.1.0. I'm using eppy only to process Lights and ElectricEquipment objects in the idf file.
After processing, the output idf file won't run through. Error file shows severe errors on Controller:MechanicalVentilation. When I compared the idf file with the original one, it seems that for "Controller:MechanicalVentilation," with >50 Design Specification Outdoor Air Objects, the new idf file only keeps the first 50. As a result, lots of the zones don't have osa objects anymore.
