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

( 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,
