[Equest-users] Understanding Floors

Eek - My own explanation of the terminology is mixed up - doh!
When I say "group spaces into one zone," I'm mis-speaking, and really
talking about how one can "group zones under one system" in detailed
mode.
If I may attempt to redeem myself... here's a revised set of my layman's
definitions:
- Shells are simply groups of spaces
- Spaces are geometrical volumes, which may or may not have
floors, walls, ceilings, windows, etc. tied to them. Internal loads /
daylighting / occupancies are attributed to spaces.
- Zones are simple entities that include one space, with
additional HVAC attributes like thermostat and airflow specifics. Zones
(and their corresponding spaces) may be grouped any which way under a
System.

perhaps the question is "are you referring to a zone or a zone group?"
in the ddwizard you can specify multiple zones into a zone group. so if
every space, i.e. every room, is it's own zone, then you could add
multiple spaces to a zone group. otherwise you're just making a thermal
zone composed of multiple spaces. as far as i know.

Nick,
How do you group multiple spaces in one zone? I always thought you could
do only one space per zone.

Hey Peter,
If by "stack" you mean place one space geometrically over another, the
answer is yes. If you mean to ask whether zones can group spaces in
different elevations, the answer is also yes.
However, I would like to hammer out your wording again to be sure we're
on the same page! I think you meant to ask "Can you stack a space in a
shell?" Spaces are normally "inside" shells in a geometrical sense, as
they are generally within the shell footprint/boundaries.
Zones, in contrast, have nothing to do with geometries - they are simply
groupings of spaces with some extra HVAC/airflow properties tacked on.
Those spaces could be all over the place - at different elevations,
within different shells... pretty much any combination from my
experience.
Best of luck! If you are getting tripped up, remember a picture is
worth a thousand questions (?)...

PS to all: The SD/DD Wizards are, in my mind, kinda misleading with
regard to helping new users understand the distinction between "space" &
"zone." Some work in detailed mode will eventually lead you to
understand, but the Wizard screens inconsistently interchange the terms
and may cause others confusion in the long run... See my description
below for a simple breakdown if you are cutting your teeth on eQuest ;).

Nick,
Thanks again. Can you stack a space in a zone?
Thanks,

Peter, I think you might be leading yourself into some unnecessary
confusion with your word choices...
eQuest has 3 distinct entities:
- Shells are simply groups of spaces
- Spaces are geometrical volumes, which may or may not have
floors, walls, ceilings, windows, etc. tied to them. Internal loads /
daylighting / occupancies are attributed to spaces.
- Zones are simple entities that include one or more spaces,
with additional HVAC attributes like thermostat and airflow specifics.
You're using "floors" to interchangeable discuss all the above, it
seems. For clarity when discussing eQuest, "floors" are merely the
constructions we walk on, normally one attribute of a "space."
All that said, it's entirely possible to model a "box within a box," as
you're describing. You are limited in the wizards (by their nature)
with regard to defining zones/footprints... the best approach depends on
the nature of the space footprints you want to model. If it's very
simply two stacked cubes enclosed within a larger cube, I'd personally
model one shell, with one space carved out of the middle. Then I'd use
the detailed mode to shrink that space volume and partition/ceiling
dimensions to match the first floor office, then copy the entire space
and its componenents for the second floor. I'd adjust the largest
cube's volume (it's a space property) to correct the conditioned volume,
and be sure all partitions are correctly associating the three spaces
together... With all spaces sorted out, ensure your three spaces are
correctly grouped with regard to "zones," for association with your HVAC
system(s).
Clear as mud =)?

To All,
I just want to make sure I understand the properties behind floors. If
you have a square building volume with a smaller square inside it that
has 2 levels. EG:- an atrium as main space with 2 levels that are
offices. There will be a total of 3 floors in your model. Atrium floor,
first floor office and second floor office. Each of these will have a
designated floor to floor height. You cannot put one zone inside another
on the same floor.
Is this correct?
Thanks,
PETER HILLERMANN
