<p class=MsoNormal><span style='color:#1F497D'>I think you’ve identified
the root of your problem – I’m unsure that there’s any way to
get light in one shell to transmit to another.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>Attached and below is an example
of a project with a lot of roof monitors that does successfully measure and
account for daylighting in those spaces. A picture speaks a
thousand words, so see if this matches what you were thinking to
accomplish. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>Each monitor is a single zone
and shell (i.e. no plenum zone). Sensors are located either on the floor
or at a desk height, as appropriate to the space usage. Creating the shell
that “wraps” around the monitors is done by using “cutting
lines” in the footprint/zoning pattern – you can read up on that
strategy by searching the archives for how courtyards are modeled. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>I’ll point out, in terms
of accuracy, I have the impression that eQuest’s daylight sensors do not
accurately realize the full amount of light that should be encountered with
light shelves, light tubes, or other means of interreflected daylight, based on
my comparative daylight analyses using AGI32 (which I’ve learned to use
accurately for daylight modeling). The DOE2 help files I think also
allude to this – It’s something to keep in mind if you have a lot
of monitor overhangs, again as with the example below.<o:p></o:p></span></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Hello E-quest group,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am working on ways to implement Equest in my workflow for
the purpose of daylighting design evaluation, and I am having trouble
implementing a roof monitor. I have read the help files that describe the
limitations of Equest to perform daylighting calculations, but I have also seen
that some people have been able to implement multilevel atriums and I have seen
one application of a roof monitor. Anyways I want to give it a go before I
start programming in Daylight Factors. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Attached is an example building I would like to be able to
evaluate. My evaluation goal is to put a light meter on the bottom zone under
the monitor and see what results pop out in the detailed daylighting summary
reports (LS-G, LS-J, ect.) I would like to compare Equest results to the
results of other software/calculations/measurements I am investigating, however
it seems that no light from the roof monitor is making it to the bottom zone.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The bottom shell is all one zone and the top is all one
zone. I have found that it is necessary that the bottom zone have windows or
else no daylighting dialog screen shows up in the DD wizard, and that means no
light meter. At first I tried to make the top zone “open to below”
and then in the detailed edit mode moved the light meter under the monitor, but
the results do not indicate any light is making it from the roof monitor to the
bottom zone.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I was hoping some of you might have some suggestions to help
implement this roof monitor setup.<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
