[TRNSYS-users] Re : Problem with windows lib

[Damien Palacios]

Thanks a lot,

I just need some confirmation.
What is (or what are) the u-value used by TRNSYS ? 
Because if I change the value in "Cond(W/m2-C     )", I don't see the value 
changing in TRNBuild window type manager. 


In fact, if I am right, this value refers to this one :


Overall and Center of Glass Ig U-values (W/m2-C)
Outdoor Temperature                 -17.8 C      15.6 C      26.7 C      37.8 C

And could you please tell me if these data in the end of file are just 
indicative ?

( By the way, is there a description somewhere of the content, the units and the 
use of the W4-lib.dat files ?
Just to be able to know more things without asking so much questions! )

Thanks again,
Damien
