[Equest-users] Daylight sensor placement question

[Umesh Atre]

If I may ask a question:
It looks like you have the 2nd sensor located in a corridor the south
side of which is a glass wall. If I understand this correctly,
why would you not define the sensor as part of that corridor zone
instead of the north zone? 
Maybe a section or 3d of this space would help.

Hey all!

 

Daylight sensor placement question (see highlighted space in attached
screengrab for an illustration):

 

I have a classroom with North and South daylight transition windows, and
a corresponding North and South daylighting "zone."  The North side is
easy - those windows are on the envelope wall, so I'm sure the daylight
is correctly being measured/modeled within the space for the "North
zone" sensor to pick up on.

The south windows however are in an internal wall, and on the other side
is a "glass box" corridor.  Rather than pursue the fuzzy route of trying
to model daylight transitioning between zones correctly (if anyone can
fully digest the help file for INSIDE-VIS-REFL I would really appreciate
the layman's explanation), I've taken the "easy" route and located the
daylight sensor in the corridor.  This happens to conveniently match the
actual design location of the photocell.  

 

My question has two parts:

*         Can a zone's daylight sensor be located in another zone and
measure light in a remote location?  If so, are any extra steps
necessary?

*         I see my eQuest project is, on its own, generating an LS-M
report for each "Daylight Illuminance Ref Pnt 1."  What is the procedure
to generate the same reports for "Ref Pnt 2" where those occur?
