[TRNSYS-users] question

[David Bradley]

Salim,
  Adrien's response was quite correct. I would only add that for some 
door constructions, it is necessary to define the door material as a 
"massless layer" (in other words assign it a thermal resistance but no 
thermal mass). If the door is thin or doesn't have much mass, it may be 
hard for TRNBuild to generate the conduction response factors for the 
door. Telling TRNBuild that the door is just an R-value solves the problem.
Kind regards,
 David
