Hello,

I am an undergraduate student trying to simulate HVAC faults using Openstudio, I have downloaded the NREL fault measures and added them to my measures folder. The model I am using is the Small Office DOE Model.

I have been trying to resolve an error I encountered when trying to apply the CondenserFoulingChiller measure into my model. https://github.com/NREL/OpenStudio-fa...

The error message: Could not set argument 'chiller_choice' to value 'Chiller Electric EIR 1' :/ruby/2.7.0/gems/openstudio-workflow-2.2.0/lib/openstudio/workflow/util/measure.rb failed with message Error assigning argument in measure :/ruby/2.7.0/gems/openstudio-workflow-2.2.0/lib/openstudio/workflow/util/measure.rb. Failed with Could not set argument 'chiller_choice' to value 'Chiller Electric EIR 1', :/ruby/2.7.0/gems/openstudio-workflow-2.2.0/lib/openstudio/workflow/util/measure.rb:226:in `apply_arguments_2'

I am still a beginner with this software so a dumb down explanation would be greatly appreciated.

Thank you

Hi, sorry for such late reply. There are many things that I can think of. And I'm going to assume you are using OpenStudio (either app or cli) for 1) creating DOE small office model and 2) applying fault measures. First thing that I can think of is, the fault measures were tested against specific version of OpenStudio (<=3.1) and Ruby (<=2.5.8). The error msg you have there seems like you are using Ruby 2.7.0 and prob OS 3.2? I haven't had a chance to test on the latest version but that might be the first think to check.
