[TRNSYS-users] importing new WINDOW LBNL Glazing to TRNBUILD Librarys

[Christophe Plantier]

Dear TRNSYS Users,

I would like to create new "european" glazings in Window LBNL to import 
them to TRNBUILD Librarys.

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.

It seems glazings listed in all W4-lib.dat have been calculated with 
NFRC American Standard, as I can read in multizone building documentation :

/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/

So my questions are :

- 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 ...
- 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 ...)

Best regards
