a caution: eQuest’s results do not have any inherent degree of accuracy/in-accuracy
with regard to the modeled energy consumption resulting from daylighting
controls – that depends pretty much entirely on how closely you define the
daylighting systems’ behavior to reality. If you have a program which you
perceive to be producing more accurate hourly percentage consumptions for your
spaces, then by all means – there’s nothing stopping you from defining a
schedule in eQuest to match the other program’s results. <o:p></o:p></span></p>

<p class=MsoNormal>E.G. Would it be accurate to model an external light shelve
as a horizontal building shade with a high reflectance value on the skyward
facing surface? I understand the day lighting benefit in Equest would be
inaccurate, but we are using separate software to obtain accurate day lighting
results. Thanks!<o:p></o:p></p>
