[TRNSYS-users] Error

[David BRADLEY]

Meryem,
   your FENÊTRE_120 is set to use the "internal calculation" algorithm 
for the convective heat transfer coefficient on both the front and back 
side. However, FENÊTRE_120 is used as an external window and cannot be 
if its back side convective heat transfer coefficient is calculated 
internally. The algorithm used is for natural convection heat transfer 
but the outside of buildings are much more dominated by forced 
convection so Type56 does not allow you to use the "internal 
calculation" algorithm for external surfaces.
Regards,
  David
