Wang, 
      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  
    Regards, 
     David

    Dear all, 
       
      I have a small question for Wall/Area definition in TRNBuild using
      TRNSYS 16. 
       
      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?   
       
      Thanks! 
      Br.

            Dear Laurent Georges, 
              
            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. 
              
            Thank you, 
              
            Matt Duffy

                Dear TRNSYS users, 
                  
                When using the Type15 to read
                    the Meteonorm weather file of a location at high
                    latitude (e.g. Tromsø in Norway), the simulation
                    stops with the following error in middle of the
                    summer period : “An simulation time step is
                      greater than the data time step for the radiation
                      calculation.  The simulation time step needs to be
                      reduced.” This error only occurs if the
                    simulation time step is taken lower than 1h, and the
                    reduction of the time step does not prevent the
                    simulation to crash. Does someone has an experience
                    with that? Is there a way to fix the problem? I am
                    using TRNSYS 17. 
                  
                In
                    advance, thank you, 
                Best
                     regards, 
                Laurent
                    Georges
