    <p>Imane,</p>
    <p>  How you handle stairs will depend a bit on the building. In
      larger buildings that have a stairwell then I would model the
      stairwell as one (or perhaps a few) zones stacked vertically. I
      would not bother to draw the doors that lead between the stair
      well and the rest of the building; I would let Type56 treat them
      as wall area. <br>
    </p>
    <p>  If you are dealing with a residential building and the stairs
      are open then energy will transfer more by natural convection than
      by conduction. TRNSYS by itself does not model the up and
      downflowing air through a stairway so you'd need to implement
      either a TRNFlow or a CONTAM model in order to assess the quantity
      of air transfer.</p>
    <p>  When I have had to deal with open stairs, I have modeled the
      opening between floors as a massless surface with a very low
      thermal resistance and have defined a coupling air flow rate. The
      air flow rate is then calculated by CONTAM (Type97) and is passed
      to Type56, which in turn passes the upstairs and downstairs
      temperatures back to Type97.</p>
    <p>kind regards,</p>
    <p> David</p>
