[Equest-users] Define a zone as open to below

[Bishop, Bill]

Udana,
 
Try assigning the roof surface that contains the skylights to the ground
floor space that contains the daylighting sensor.
 
Regards,
Bill

I'm in need of placing a day light sensor to sense day light coming from
the skylights and control light level of the ground floor accordingly.
even though i make the first floor open to below the sensor doesn't seem
to take skylights in to account. is there anyway to sense the light
coming from skylights to control the lighting level with a sensor that
is placed in the floor below?

Thanx & Best Regards,
Udana.

Before I was aware of 'open to below' and similar options in the wizards
(oh, the perils of being self-taught!), I came up with a practice of
creating multi-story spaces by making separate zones for each level from
the wizard, then in detailed mode deleting all but the lowest, then
modifying the remaining space/zone to get the correct height/volume.
 
Some further tips:
-          Once done with the geometry edits, review that space's
internal loads - you may want to revise depending on your situation.  
-          You might consider for very tall spaces whether there is an
"unconditioned" layer from an HVAC perspective that you might want to
define as a separate, unconditioned space (think plenum).  
-          You can optionally pursue extra steps to tie the bounding
surfaces of adjacent spaces to the multi-story space if you deem it
necessary for accuracy.  If you anticipate you'll want to do this, pay
attention before deleting the individual multi-story spaces so that you
don't accidentally remove some surfaces you'd like to have associated
from the adjacent spaces... this is a case where thinking ahead a few
steps can save you a headache later.

I'm modeling a two storied building with a mezzanine area in the first
floor and i need to define the rest of the first floor area apart from
the mezzanine as open to below. is it possible to define a particular
zone as open to below in the detailed mode? if so how?
Thank you in advance.
