the baseline I only considered a very small portion of the wall to be “lit”.
This caused my baseline allowance to be lower than my proposed which set off a
red flag for the LEED reviewer due to Exterior Lighting Power density being a
mandatory provision of ASHRAE 90.1-2004.<o:p></o:p></span></p>

<p class=MsoNormal style='margin-bottom:12.0pt'>I would divide the 500 Watts by
the entire 100 lineal feet of the wall the fixture is on. I don't see what you
would gain by just considering the lit area of the wall but I can see where you
might be penalized. Since it's just an exterior load there aren't any
interactive effects to worry about either.<br>
