    Wang,<br>
      There has been a debate about this question in the industry for
    some time. I think the consensus is that the dimensions of the room
    should be taken from wall center to wall center and from the top of
    one floor to the top of the next floor. If I am reading your case
    correctly, I think the areas should be based on the dimensions 9.1,
    7.1, and 3.1m <br>
    Regards,<br>

      <br>
      I have a small question for Wall/Area definition in TRNBuild using
      TRNSYS 16.<br>
      <br>
      What does Wall/Area exact definition in TRNBuild mean? Does its
      area include the thickness of wall or not? i.e. How do we
      calculate wall's area in TRNBuild? If the netto room volume was
      9*7*3 m3 (length*width*height), the gross was 9.2*7.2*3.2 m3, the
      Area of floor/ceiling should be 9*7 m2 or 9.2*7.2 m2?  <br>
      <br>
      Thanks!<br>

            <p>This should not be an issue now with the latest version,
              17.01.0025. Please make sure that you are using this
              version, and if you continue to have problems, please send
              me the *.tpf.</p>
            <p> </p>
            <p>Thank you,</p>
