 Therefore, the base floor area of the stairwell is simply multiplied by the clear height of the storey. The volume for flights of stairs and intermediate landings does not have to be subtracted.
-The volume of elevator shafts and any other kind of shafts inside the thermal envelope are part of the air volume and is fully taken into account. The volume of  the elevator, pipes etc. themselves (building component) is not taken into account, therefore it is not deducted. The base area of the shaft can thus be multiplied with the clear height of the storey.
