Importing a CAD file

To all,

I am walking through eQUEST and just learned how to insert a CAD file. I
have customized the footprint and outlined the zones. Unfortunately I do
not know how to assign different HVAC units (systems) to different
"zones". When I get to the 'zone group definition' page there is only 1
zone listed though I outlined 6 on the 'building footprint' page. Any
help is appreciated!

Thanks,

Christine Gries

Hi Christine,

First I saw your email earlier - just so you know, this program does
have a tricky/steep learning curve, but you're in the right place to ask
questions and find classes if you desire.

The DOE2 help files in eQuest are deceptively more helpful than they may
initially appear. Tons of information in there, though it can be quirky
to navigate... remember you can right-click nearly any input field in
the wizards and particularly in detailed mode to pull up the help files
- when you're lucky it leads you straight to a pertinent entry.

Bookmark these mailing list archive links for your own eQuest
help/reference. There's some good general beginner's advice to start
with therein, search for my name for a few lengthy posts:

-
http://lists.onebuilding.org/pipermail/bldg-sim-onebuilding.org/

If all else fails, here is a great place to ask a question... though
helpful responses may be delayed/erratic depending on who has time/drive
to help out - a lot falls on the questioner to craft and draft a clear
question.

To your current question: In the wizards (before detailed mode) you can
define HVAC systems by backing out of the shell wizard window, and
looking to the right side of the main wizard window. Once an HVAC
system is defined, you can jump back to the shell wizard and
re-define/re-assign zones to your new system(s) at the zone group
definition page. HVAC systems are further defined in the detailed mode
to include items like ERV, various economizer functions and much more.

What you are seeing is a "zone group" definition, which includes all of the
thermal zones you defined previously. If you look at the botton of the
page, you'll see an outline of your building footprint with the zones
outlined. You need to add more "zone group" definitions and assign zones to
them before you can assign different HVAC systems to different zones. BUT
before you do this, look at the HVAC systems. In the first window, at the
bottom it says "System Assignment to Thermal Zones". Here you can specify
whether you want to create a system for each thermal zone, one for each
floor, one for each shell, etc. So try a couple different options and see
what happens when you go to detailed edit before you go to the trouble of
creating a separate 'zone group' for each zone.
