1. Pressure distribution in the region of typical floors caused by stack effect can be easily explained with "Exterior wall pressure load ratio K'" which is defined as |ΔP_w|/(|ΔP_w|+|ΔP_s|), whereΔP_w andΔP_s are pressure differnce across exterior wall and elevator shaft. 2. K' is equal in principle to "Tamura's Actual/Theoretical (=K)", that was confirmed through measure-ments and computer simulation. Therefore, K has become to show more physical characterestics. 3. Specific problems generated by pressure difference, which are noise resulting from air flowing through cracks, the difficulty of opening doors, flow rate variation of air conditionning system are explained quantaively and an effective solution to the noise problem was proposed.
