My intent is to model a building with a unglazed transpired solar collector. There is an EnergyPlus object SolarCollector:UnglazedTranspired but it is not yet supported by OpenStudio. I generated my base building code using OpenStudio and then exported the IDF.

Within the IDF I changed outside boundary condition to OtherSideConditionsModel for the BuildingSurface:Detailed that the solar collector is located.

I created the SurfaceProperty:OtherSideConditionsModel with GapConvectionRadiation modeling type.

Then added the SolarCollector:UnglazedTranspired object. I cross referenced the appropriate boundary condition model and building surface name that were previously discussed. Inlet, outlet and setpoint node were referenced. Zone node name is the only input I am unsure about and have tried several logical options without success.

The error I receive, shown below, states that the object is being ignored.

* Warning * The following lines are "Unused Objects". These objects are in the idf * ~~~ * file but are never obtained by the simulation and therefore are NOT used. * ~~~ * Each unused object is shown. * ~~~ * See InputOutputReference document for more details. *** Object=SOLARCOLLECTOR:UNGLAZEDTRANSPIRED=JABS HALL UTSC

Is there an incompatibility with the EnergyPlus SolarCollector:UnglazedTranspired object and how OpenStudio generates the IDF code?

Has anyone had this issue before?

Why would a completely defined object be unused in EnergyPlus?

I would appreciate any help or suggestions. Thank you!

This warning is telling you that you haven't referenced the SOLARCOLLECTOR:UNGLAZEDTRANSPIRED in your air system. Typically, it should appear in the outdoor air system. You can see how it's referenced in this example file.

That was it. Thank you for the help.
