class=167075318-16112009>It may be dangerous to conclude that the windows make a
difference with the increase in energy usage in the winter time. Most buildings
have interior shades that people use when the sun is shining in their window. I
can't ever remember a time when I changed eQuest's default interior shading, and
in previous modeling, I always assumed that there was no interior shading. (For
the purposes of doing loads this made sense as it would get me the worst-case
load on the zone in question)</SPAN></FONT></DIV>

class=167075318-16112009>If people are drawing their shades, then the heating
effect by sunlight would be reduced. This is the case for either the "better"
glazing or the "standard" glazing. So while your model will still show greater
energy usage due to the fact that sunlight is reduced, it probably isn't going
to be to the degree that it indicates, unless you did account for interior
shading in your model.</SPAN></FONT></DIV>

color=#0000ff size=2>Higher gas usage. Electric is virtually
unchanged. I was designing to mitigate heat gain in the summer and had not
considered the effect it would have in the winter. Now that I think
of it, the building is in San Francisco so I assume the summer heat loads
must be negligible since the building has no A/C. Thank you for your
prompt response.</FONT></SPAN></DIV><BR>

has a higher absorptivity and thus doesn't allow as much sunlight in the
structure in the winter, thus requiring a larger amount of gas to

<P><FONT face=Arial size=2>I ran a very quick and dirty EEM to compare the
effects of using a different glass type when compared to the baseline model,
which was created in the SD Wizard. Contrary to my expectations, the
higher performance glass resulted in<I> higher</I> annual energy usage!
The glazing is the only component I changed in the model. If anyone can
speak to this result, I would appreciate it.</FONT></P>
<P><FONT face=Arial size=2>Thank you…DD</FONT>
