<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I have noticed that on a couple of my eQUEST models, when daylighting
is used, that turning the daylighting controls on creates a small <u>reduction</u>
in heating energy. Intuition (and a number other modeling projects)
suggests that the opposite should occur; when daylighting is implemented the
decrease in lighting energy should create an <u>increase</u> in heating
energy. In my model this occurs largely in the winter months, so it is
not likely to be due to reheat effects. And the load component reports do
not reveal this increase, so I don’t know what part of the load is
changing.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>In one example, I’m doing a small daylighting study on
a typical office unit in <st1:State w:st="on"><st1:place w:st="on">Wisconsin</st1:place></st1:State>…I’ve
attached the .inp and .pd2 files for your review. I have turned
daylighting on in parametric run #7, if you’d like to compare that with
the baseline. If anyone sees a quirk in my model setup, or feels there’s
some good reason that eQUEST would give this result, I’d be happy to hear
your thoughts. Thanks for your time -<o:p></o:p></span></font></p>
