[Equest-users] Exterior Facade Lighting

[Nick Caton]

Hi guys,

 

Richard's question suggests he may not be in detailed mode yet.  You
will need to wrap up Wizard mode (SD/DD) if you haven't already - do
enter the installed kW for your exterior lighting system(s).

 

That load (kW) will show up as a direct exterior load on your electrical
meter (under 'utility and economics' tab) once in detailed mode.  You
assign a schedule there, and can break your exterior load into multiple
loads if you have different controls /scheduling to model (i.e.
perimeter lighting turns off at midnight, other lighting is all night,
garage lighting is 24/7, etc..).

 

Attached is a mailing list discussion where I basically shared a series
of schedules that anyone can use (in eQuest versions 3.63 and onwards,
as Steven says!).  If you paste those schedules into an .inp file that
you keep handy, you can simply import them into your current and future
projects, then assign those schedules via dropdown selection box at your
meter.  Pretty simple ;).  

 

If you need more help importing, search for my name to find an importing
tutorial in the archives.

 

Best of luck,

 

~Nick

 

PS:  the DOE2 manual entry copied below is a little misleading - if you
set it up as an ON/OFF schedule as suggested, you won't be able to
select that schedule for a load assigned to a meter... the workaround is
to use type MULTIPLIER per the attached, and PHOTOCELL-CTRL will behave
properly ;).

Richard,

 

First, which version of equest are you using?

 

If it's a newer version (think this was added in 3.63), then you can use
the photocell override keyword (excerpt from the doe2 manual below).  I
believe you'll need to add this in the .inp file, as I don't believe
there's a way to do this from the interface.

If you're using an older version, you're stuck creating more complicated
schedules.  In the past, I've accomplished this by creating a fraction
schedule for each month with the average sunrise/sunset times.

PHOTOCELL-CTRL


Accepts a code-word specifying whether the hourly value in the
referenced DAY-SCHEDULE can be overridden either ON (value = 1.0) or OFF
( value = 0.0) according to whether it is day or night.

DAY-OFF                     Forces the hourly schedule value to be 0.0
whenever the sun is up.

DAY-ON                       Forces the hourly schedule value to be 1.0
whenever the sun is up.

NIGHT-OFF                  Forces the hourly schedule value to be 0.0
whenver the sun is down.

NIGHT-ON                   Forces the hourly schedule value to be 1.0
whenever the sun is down.

For example, assume lighting in a parking lot is to be on from dusk
until 11 p.m. The earliest the lights are allowed to illuminate is 4
p.m., but will not actually start until the sun is down:

"Parking Lot DSch" = DAY-SCHEDULE-PD
TYPE               = ON/OFF
VALUES             = ( 0., 0., 0., 0., 0., 0.,
                       0., 0., 0., 0., 0., 0.,
                       0., 0., 0., 1., 1., 1.,
                       1., 1., 1., 1., 1., 0. )

"Parking Lot WSch" = WEEK-SCHEDULE-PD
TYPE               = ON/OFF
DAY-SCHEDULES      = ("Parking Lot DSch")
..

"Parking Lot Sch" = SCHEDULE-PD
TYPE               = ON/OFF
PHOTOCELL-CTRL     = DAY-OFF
MONTH              = (12)
DAY                = (31)
WEEK-SCHEDULES     = ("Parking Lot WSch")
..

I have created an exterior lighting system under the tab lighting
systems but I am not sure how to assign a schedule to this system. The
lighting will be controlled by a photocell.
