program for calculating total window thermal performance indices (i.e.
U-values, solar heat gain coefficients, shading coefficients, and visible
transmittances). WINDOW 6.3 provides a versatile heat transfer analysis method consistent with the
updated rating
procedure developed by the National Fenestration Rating Council (NFRC) that
is consistent with the ISO 15099 standard. The program can be
used to design and develop new products, to assist educators in teaching heat transfer

codes. <br></font></p><p><font face="Arial" size="3"><br></font></p>

Yes, I am modeling for LEED purposes.<br>
I'll look into A8.2. But at least, is my method correct for the proposed
scenario?<br>
<br>
Brad: I think you need to enter the center of glass u-value in the "Glass
Type", and then enter the frame properties in the "Window"
properties...<br>

<br>
Is the u-value listed for a manufacturer and specific model on the NRCAN
website centre of glass or overall assembly? Many windows are custom made
to suit so I am unclear if each individual custom window would need to be
tested.<br>
<br>
<br>
<br>
In eQuest, when entering the window, if the u-value represents the whole
window, including frame, do you need to enter a frame width, conductance etc as
well under the Window Frame section under Window Properties? Thanks.<br>

Omar,<br>
<br>
The answer depends on the purpose of your study. If you're trying to get
results for a client on the impact of the glazing on their energy performance,
this may be adequate. Make sure you've entered in the framing information
properly (metal vs. non-metal).<br>
<br>
I'd recommend opening up your simulation output results file (xxxx.SIM) and
going to the either the last page of the LV-D report or sort through your LV-E
report to see what value eQUEST has calculated. Compare these values to the
ASHRAE Fundamentals results for overall assembly values including frame to see
how close you've come. I would not blindly trust that eQUEST will give
you an appropriate overall assembly value based on entering only the center of
glass number.<br>
<br>
However, if this is for a LEED study, this is not adequate. This an
excerpt from an e-mail I sent out recently regarding LEED and NFRC
requirements.<br>
<br>
In order to meet LEED EAp2 Minimum Energy Performance, the project must comply
with all mandatory provisions of ASHRAE 90.1-2007. Section 5.4.2
Fenestration and Doors requires that fenestration performance be determined per
section 5.8.2. Section 5.8.2.4 U-factor requires that the U-factor for
the overall fenestration area (including framing) be determined in accordance
with NFRC 100. If you do not have NFRC data available, values from section A8.2
are the only acceptable alternative.<br>
