              every body,
              <div><br>
              </div>
              <div>I now have a difficult problem. I found that the
                autosized design air flow in the first floor is much
                larger than the second floor, about 5-10 times of the
                second floor. I cannot figure out the reason, because
                the indoor lighting, equipment power and the occupant
                density are all the same for the two floors.</div>
              <div>In my opinion, the second floor should have a higher
                air-conditioning load than the first floor because it is
                the building's top floor. But the result is just the
                opposite.</div>
              <div>I really want to know the reason and how I should
                deal with it.</div>
              <div>Thanks</div>
