<p class="MsoNormal">Sorry I should have made it clear that I am modifying an
existing DOE2.1e file done in EE4 which does not include any information on
framing. I am therefore attempting to lump framing u-value in with glazing
u-value to save the effort of defining window frames one by one, which isn’t so
bad and its what I ended up doing.</p>

<p class="MsoNormal"><o:p> </o:p></p>

<p class="MsoNormal">But came across an interesting problem with imported
glazings from WINDOW6.3. When I compare glazing done in WINDOW6.3 with the same
glazing from the eQUEST library I get different center of glass U-values
reported in LV-H section of the SIM file. I constructed SB 70XL on Starphire/Air/Clr
6 in WINDOWS6.3 and imported it into eQUEST, all the glazing properties were
approximately consistent with the values from the library glazing however when
I simulate and look at the report I get a center of glass U-value of 0.290 for
the SB 70XL on Starphire/Air/Clr 6 glazing from eQUEST library but a U-value of
0.223 for the glazing created in WINDOW6.3. What am I missing here?</p>

<p class="MsoNormal"><o:p> </o:p></p>

<p class="MsoNormal">Furthermore, when I edit the .inp file to hard code a
U-value of 0.849 into the library glazing and my WINDOW6.3 glazing like so,</p>
