My model has a lot of unmet load hours, but the simulation fails when I apply the Unmet Load Hours Troubleshooting reporting measure. Here is the link to my .osm file. https://drive.google.com/file/d/1cwh1...

Here are the error messages I receive.

Found error in state 'ReportingMeasures' with message: 'Runner error: Measure 'C:/Users/DARIUS~1/AppData/Local/Temp/osmodel-565e-2c55-775f-1946-1726977606-0/resources/measures/UnmetLoadHoursTroubleshooting/measure.rb' reported an error with [SWIG director method error. NoMethodError: undefined method `iddObjectType' for nil:NilClass

This error message appears after it gathers reports.

I appreciate any insight anyone can provide! Thank you.

The measure assumes you have a SetpointManager assigned to the supplyOutletNode of your AirLoopHVACs. Which you apparently do not have.

https://github.com/NREL/openstudio-co...

You probably should... I fail to see any valid case where you would not.

I filed https://github.com/NREL/openstudio-co... so the error handling gets improved.

Edit: I opened your model, I see you placed a SPM:Coldest after the heating coil and a SPM:Warmest after the cooling coil.

I don't think this is going to work like this. AFAIK, if you want to use both, you should probably use a Dual Duct AirLoopHVAC, similar to the DualDuctConstVolDamper.idf EnergyPlus example file (https://github.com/NREL/EnergyPlus/bl...)

It'll look something like this:

Thank you for taking a look and providing your input! It is not supposed to be a dual duct system so I removed the existing SPMs and now only have the SPM:Warmest at the end. However, I still cannot seem to get the reporting measure to run. Here is the updated model: https://drive.google.com/file/d/1on4F...

You see where it fails, you can track the line it throws on and figure it out. It happens here: https://github.com/NREL/openstudio-co...

Do yourself a favor, and stop using special chars in your object names (and file names), in particular DO NOT use commas. You can manage to do everything with [a-zA-Z0-9] and - and _ and you'll avoid a lot of problems. If I name the zone Thermal Zone: 2FL_Office203-204-205 instead it works (1/2)

It will fail later anyways because this measure is not compatible with 3.0.0. cf https://github.com/NREL/openstudio-co... and https://github.com/NREL/openstudio-co...
