Dear TRNSYS Users,<br>
<br>
I would like to create new "european" glazings in Window LBNL to
import them to TRNBUILD Librarys.<br>
<br>
In WINDOW 7, I have to choose between NFRC American Standard and
European Standards (EN 410 and EN 673). Values of U-Value and
g-Value are quiet differents between these two standards for the
same glazing.<br>
<br>
It seems glazings listed in all W4-lib.dat have been calculated with
NFRC American Standard, as I can read in multizone building
documentation :<br>
<br>
<i> 8. "WINDOW 4.1, PC Program for Analyzing Window Thermal
Performance in Accordance with Standard NFRC Procedures", Windows
and Daylighting Group, Building Technologies Program,
Energy and Environment Division, Lawrence berkeley Laboratory, CA
94729 USA, March 1994</i><br>
<br>
So my questions are :<br>
<br>
- Can you confirm that all glazings listed in W4-lib.dat, specially
in the German library, have been calculated with NFRC American
Standard ? Even the Saint-Gobain CLIMAPLUS FUTUR AR 1.1 4/15/4 ? For
this one I find the same values between Trnbuild library and
european standard Window 7 results ...<br>
- In this case, how can I translate values between the two standards
? (It's a big problem for me : during 15 years I asked trnbuild
values to my glazing manufacturers but they used obviously european
standards ...)<br>
<br>
Best regards<br>
