If I am following correctly, you need to be sure that there is only one driving force for the time under consideration. No internal gains, no infiltration, and no solar. Also, all non-adiabatic surfaces need to have the same outside boundary condition. For example, a floor slab which has a ground boundary condition that is different from the outdoor air temperature would cause a difference.
