not getting the heating energy provided by that light), but you are certainly
adding a bunch more in solar gain. Being originally from Chicago, I remember
sitting in my parent's car in the dead of winter, but wanting to take my coat
off with the full winter sun shining into the car windows.</FONT></SPAN></DIV>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; 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 face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; 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
