Hi Ben,<br><br>How about using the WIN program, see LBNL website. You can create the exact window you want and then use the import function in eQUEST to bring the data in.<br><br>Carol<br><br><div class="gmail_quote">On Tue, Aug 24, 2010 at 8:47 AM, Ben Pressman <span dir="ltr"><<a href="mailto:bpressman@practicalenergy.net">bpressman@practicalenergy.net</a>></span> wrote:<br>

<p class="MsoNormal">I am trying to replace a single-pane, clear
glass window
with an aluminum frame, no thermal break with a double-paned,
argon-filled,
low-e, tinted window with a thermal break in a parametric run.
When I enter in
ASHRAE 90.1 U-factor and SHGC for the new window, the resulting
energy savings
is significantly less than expected by a quick manual estimation.
I suspect
that I am confusing NFRC U-factor for center-glass U-factor given
in the DOE2
glass library. I know the NFRC U-factor I want to use which
accounts for the
type of glass and the frame type. In eQuest, however, it appears
that the glass
and frame conductances must be entered separately. Is there a way
to enter the
NFRC U-factor instead or determine from the NFRC U-factor what the
frame
conductance should be? Has anyone had similar problems?</p>
