[TRNSYS-users] u-value of a wall : which Ntype?

[David Bradley]

Eleni,
 It is not exactly correct because it is not time dependent and uses 
default interior and exterior convective coefficients but I usually use 
the u-value shown in the *.inf file as my reported u-value for walls. I 
do not think that there is a special ntype for the u-value of walls. 
Please someone correct me if I am wrong about that!!

 As for NTYPE86, it is the equivalent thermal resistance (r-value) 
between a given (user specified) surface and the star-node (for 
radiation exchange calculations).

Kind regards,
 David
