Adiabatic (asymmetrical) walls in Eplus

Hi.

I've been reading up on how Eplus handles the adiabatic boundary condition. Documentation says: "EnergyPlus will apply the same boundary conditions to each side of the construction so that there is no temperature difference across the surface."

I get why this would work well for symmetrical walls, but what if you have a typical concrete slab floor with insulation and wood on top? As far as i can tell, wouldn't that cause potential heat exchange/loss to that construction element?

Hope that was clear. :)
