[Equest-users] URGENT: Window U-values: Total window assembly v/s Glass only

[Omar Katanani]

Dear all,

 

I have a small question regarding entering window properties to eQUEST:

 

I have read a lot of emails in the forum discussing NFRC testing, LBNL
Window 5 import, and other topics that I haven't paid attention to
before. 

 

The way I modelled my windows is the following:

 

1.	I have manufacturer's specifications listing the glass U-values,
not the total assembly.
2.	In the "Glass Types" (eQUEST Detailed Mode), I created glass
types, and entered the glass conductance, visible transmittance, SC, and
emissivity from the manufacturer's details I have.
3.	When creating windows, I specify which glass type (from the ones
I created in step 2), in addition to the frame width and conductance.

 

I'm assuming that, given that I entered the u-values for the glass only,
and then I entered information about the frame, then I need not worry
about any conversions in U-values, since eQUEST has all the necessary
information to calculate the equivalent u-value of the whole pane +
frame assembly, right?

 

I appreciate your feedback / comments today if possible, as this has
become really urgent!

 

Many thanks,

Omar
