[Equest-users] exterior lighting, non HVAC loads.

[Nick Caton]

To add a small bit:

 

While we can define exterior lighting loads (in W/ft^2... how
intuitive!) in either SD or DD wizards, I only ever do so if I must stay
out of detailed edit for some reason.  In detailed, as described below,
you can (1) enter the fully connected load as you might tally it from
the design, in kW, and (2) you may assign a variety of scheduling to
accurately model the consumption (photocell controls/timers/fractional
loads/etc...).  

 

Related Question/Food for thought:  If I'm not mistaken, there's nothing
in the SD wizard screens you can't do in the DD wizards, which offer
more flexibility (>2 systems/multiple shells)... Am I missing some
compelling reason to start a project in SD vs. DD wizards?

You may need to be in the DD wizard to do this.  The project I have open
is beyond the SD.  Finish all your basic setup in the SD wizard for the
first floor and change to DD wizard.  Use a copy and nothing is lost.  I
will stay for hours or days at the finish button of the Project
Navigator in the DD wizard doing incremental edits, saving each time.
Each time you press finish your project is run, confirming equest is
happy with your changes.  In building shell, using the action tab
select, building creation wizard, and it will bring up the project
navigator after a warning about losing everything you entered in
detailed edit.  Be working with a copy and ignore the warning.  Don't
add anything after this screen and you have nothing to lose.  You can
also go back and forth as many times as you like.  Select your Bldg
Envelope and Loads 1, that should be all you have coming from the SD
wizard.  To add the Keith's post, you may need to go to screen 15 first,
non-HVAC End uses to Model, select exterior lighting, select mode.  This
will turn on screen 23, go there next, set your W/sq.m and you profile
details.  Note screen 15 is a gateway to adding many other options and
turning on other screens.  If you are missing screens you need to go to
earlier pages and find the check box to open other screens you may wish
to add information on.

Yehuda,

 

If you are in the DD wizard, you can enter exterior lighting on Screen
23 of the building shell screens. The area for the watts per square foot
is the interior building floor area, not any exterior surface area.

 

If you are in the Detailed Interface, click on "Utility & Economics" in
the upper right. In the Component Tree list on the left side of the
screen, select "Electric Meters." At the top of the screen, select the
Display Mode to be "Electric Meter - Direct Loads - Exterior." Here you
can enter the exterior lighting loads in kW (instead of W/sf like in the
wizard).

To all:

 

I am trying to model an outdoor park lot that has outside lights.  How
do I add the lights to my building model?

 

Thank you.
