If you are referring to the Change Overhead Ventilation to Displacement Ventilation measure on the BCL, this measure will add a RoomAirSetting:ThreeNodeDisplacementVentilation EnergyPlus object designed for representing a low velocity floor-level displacement ventilation air distribution system. This isn't your exact case of no forced air, so use it with some caution.
Because this measure "injects" this EnergyPlus object into your translated EnergyPlus file from OpenStudio, you won't see its related Output Variables in OpenStudio. However, you can add these using the Add Output Variable measure from the BCL. Here are some Room Air Model variable names that you may be interested in:
You'll need to apply this measure for each output variable that you want to report. After applying all the measures, save your Openstudio model, run a new simulation, and you should see the new output variables appear in the generated CSV file from EnergyPlus. If your OpenStudio file is named My Model.osm, you can find this CSV file in the folder My Model / run starting in the same folder where My Model.osm is saved.
