[Bldg-sim] Multiple roof heights

Pranita,
For eQuest, a model requiring multiple roof heights will typically
involve defining multiple shells using the DD wizard. Whenever defining
multiple shells, it's most time efficient to define all aspects of the
first shell (not just geometries) before starting the 2nd, as you'll be
able to copy those inputs at that stage instead of re-entering
everything manually twice. It is not a bad idea however to try creating
your shells defining only geometry first, as a "practice run," to ensure
you understand the process.
When defining adjacent shells - it's best to understand what eQuest will
actually do: the current behavior is to define adiabatic walls between
the adjoining spaces - changing those to 'air' or 'standard' interior
surfaces (in detailed mode, after the wizards) is necessary to model
heat transfer between the spaces.
I've replaced the unrelated discussion below your query with a related
(identical) query from the [Equest-users] mailing list that should help.
The referenced posting by Scott Criswell is attached as well, and helps
to further outline the wizard's behavior.
For future reference, you are most likely to get prompt and helpful
responses for eQuest-specific queries on the [eQuest-users] mailing
list. I'd also advise bookmarking the following archives as well as
another great resource while learning eQuest - as you are learning you
may find questions you come up with are already answered within:

Hello -
I am new to eQuest and have been trying to model a sports center in the
DD Wizard. I created the basic plan in autoCAd and was able to trace it
in eQuest. The building has multiple roof heights (flat roof).
My question are:
1) how do we model a building with differnt roof levels.
Thank You.
Pranita.

I would suggest side-to-side over stacked.
If you position via coordinates, and can get the adjacent planes to be
in the same locations, eQuest will recognize the coincident planes and
automate a number of things for you. You cannot do this via stacking
shells on top of each other.
I'd suggest reviewing some specifics regarding how you go about
positioning your shells from this mailing list discussion. I can't seem
to find it in the archive to link to, but Scott Criswell outlined some
pointers pretty helpful to the task at hand. I've attached the
discussion for your review =).
I'd also suggest bookmarking this archive search page if you haven't
already - you'll find more information regarding shell placement if you
find further trouble getting your shells to line up just right:

It might be easier to make the two shells stacked instead of
side-by-side. That way, you can specify that the top shell is open to
below and by zoning the bottom shell properly, you can make the part
with the high ceiling open to above. Just a thought.

Subject: [Equest-users] How to model a bldg with different roof levels?
Hello everyone,
I was trying to model a bldg with 50% area at 25 feet high and remaining
area at 10 feet. How can I specify different heights in the footprint
of this bldg. in eQUEST? I tried to draw in DD Wizard. First I drew a
footprint with 25-foot height, then I tied to create a new shell with
10-foot height. I wasn't able to put two shells together. Also, I didn't
know how to change exterior walls to interior.
Any help would be appreciated .
Regards,
Aman
