True.
· Because I also think E+ was not intended for this unusual situation, and it is probably a small influence overall, I would define the floor as if it were in contact with the ground and call it “good enough”.
Consider using "otherside coefficients" to define the otherside temperatures for this floor. Think about looking at the Composite Wall Construction approach for creating the layers of the floor.
Not intended vs being able to model this? EnergyPlus can likely model it.
