I want to modify the existing HVAC system of a DOE prototype building with a Radiant heating/cooling system. For doing this, I wanted to apply the "AedgOfficeHvacRadiantDoas" measure to a Medium office DOE prototype building previously loaded as a measure in OpenStudio. However, I am getting an error that says: "undefined local variable or method 'plantLoop' for OsLib_HVAC:Module". How can I solve this issue? Thanks in advance for any help you can provide.
