Hi Pietro,<br>
<br>
Sorry I can't help you with that one. But I also noticed some difference
between the U value given by WINDOW5 and the one showed by TrnBuilt,
especially when you use Krypton between the glasses.<br>
Does anybody have an explanation for that ?<br>
<br>
Best regards,<br>
<br>

<font face="arial" size=2>sorry for another question,</font><br>
<font face="arial" size=2>I "decoded" the reported data from
Window 5 as edited in W4-lib.dat file in order to describe the global
value as described at the "END OF THE LIBRARY" in this file
(see the example below). I found an exact corresspondence for all the
data except for the U-value, whose reported value I suppose to be a mean
value of the reported ones in the "Overall and Center of Glass Ig
U-values (W/m2-C)" lines. but which ones?</font><br>
<font face="arial" size=2>Otherwise I thought it should simply be the
global value reported for the glazing system of a given window, but I
cannot verify it since a can't resume the Trnsys W4-lib story of
course...</font><br>
<font face="arial" size=2>can anybody confirm to me that it is correct to
assume for U-value what given for the glazing system and not get it from
the Window 5 report? </font><br>
<font face="arial" size=2>thanks in advance</font><br>
