I was trying to model a ceiling/floor surface in energyplus with radiant cooling on the ceiling side and radiant heating on the floor side using ZoneHVAC:LowTemperatureRadiant:VariableFlow objects but was having trouble with this error.
* Severe * Surface NAME_OF_SURFACE is referenced by more than one radiant system--this is not allowed
I was able to get around it by changing the BuildingSurface:Detailed field of Outside Boundary Condition from Surface to Adiabatic for the floor ceiling I was adding radiant heating and cooling to. This decoupled the surfaces in the model and energyplus ran without a severe error.
This error is mentioned in another post with a proposed solution, but references a 'Radiant Surface Type' which doesn't seem to exist.
Is this behavior a feature of energyplus, a bug, or can my idf file (Google Drive link) be changed to have a surface with a radiant system on either side with Outside Boundary Condition of Surface?
