[TRNSYS-users] Wall/Area definition in TRNBuild

[David BRADLEY]

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
