[Equest-users] Modifying Geometry

[Martz, Amanda]

What I usually do when I need to modify geometry is I save a version of
the file and call it "old", then I open that file and the file I am
working on at the same time. You can use the old file to check what
vertices and walls you had for the space after you delete it in your new
file. I think in your case, I probably would have left the space as it
was and then added a space within it. you'd have a big space, then one
inside of it. I'd then adjust the wall lengths and square footage of the
big space so it didn't overlap the other space anymore.

You're biggest problem will be when other spaces reference your old
space as a "next to." When you go into the properties of a wall, you'll
see the wall is sometimes located by what it is "next to". when you move
the old space, you're other spaces around it might get confused. Go into
the spaces immediately surrounding the space you're adjusting and make
sure you put in the newly created room as the "next to" instead of
leaving the old room there.

When you edit a 2-d view, you can type in the location of the vertices
instead of dragging the dots around and trying to get close. Use your
old file as a reference for these vertices. The corners (vertices) of
the two spaces should not be different than your old corners. Does this
help?

Wow, I didn't know I would cause all this debate!!

Anyways, I modified a zone that I want to split into 2 non-identical
zones. Then I had a hole in my building.
I created a new space and a new polygon. I fitted the polygon into the
empty hole as seen in "2D Polygon.jpg".

Then after I returned to the 2D view mode, I discovered that the space
is not located properly!! It's 9:45PM and I'm still at the office! This
modeling thing is frustrating!

I also attach the eQUEST files, if someone can please help. If someone
was very kind to clearly help me sort this zone out,  I think I can
continue the rest of the building zones modifications in peace!

Many thanks!
Omar

Wow Bill - that is cool - thanks for that.  Not sure I will be that
adept
after my 7000 square foot project, but it's good to know the
capabilities.
This building was generated in equest?  I did find where you can change
the
pitch of the roof by degrees! 



I have never use revit with equest btw - I was just reacting bitterly to
my
first go at trying to use that interface.  I tried to customize zones
and
came up with some crazy thing that looked like a tree house for monkeys.



Thanks for helping me believe.



Tim

Tim,



Yes, you can do complex roofs if you work at it and nobody reminds you
that
you're working on a deadline. (See attached.) Ditto Carol's Revit
comment
and Lan's simpler-is-better-to-a-point advice.

Tim,



I think eQuest is an energy modeling program and we are more concerned
in
BTU/ton terms - or $$ at the end. If the roof was built somewhat
differently
by modeler as it was shown on architectural drawings, my question is
only
how much it will affect the energy usage. If it is a minor, I won't
drive
myself crazy to make them same.  If you read Ashare 90-1, simplify
building
geometry for energy simulation purpose is allowed. Also when we model a
building, we can have tons of inputs and lots of assumptions are made
either
by us or by the program itself, I think majority of them can have a
bigger
impact on our goal than build a prefect roof/building shell. I might be
one
of the lazy modelers. Hope you can enjoy eQuest a little bit more.



Thanks!



Lan

If you're complimenting me on my observation, my awareness must be at an
all-time high today.



How about a complex roof shape like the one attached?  Notice ridge
lines
don't match and there is a gable at the porch end as well as the
building
end.



Can equest do that too?  As long as one would put in the training time
of
course.

Well, at least your powers of observation aren't suffering.

Yes, you can model individual ceiling heights per room. You can do
almost
anything once you take the time to learn how. What are the specifics of
what
you want to do: model a room with two different ceiling heights or model
a
bunch of rooms with one height and a bunch with another height? A
picture
would be great if ya have one.

On a related note.

Does equest have a way to model individual ceiling heights per room?



Thanks,

Tim

I have got to protest this one, sorry Tim.


Buying a Revit license to be able to accurately model geometry in eQUEST
is,
to be blunt, crazy. It's really pretty easy to revise your geometry and
if
you can't do that using one of the 3 methods I provided earlier, you
need to
figure out how to train yourself better or leave the field. It's not
just a
matter of being able to use eQUEST at this point, it's a matter of being
able to generate an accurate model using any tool. Being able to import
CAD
or Revit data into energy models is a recent development. Frankly, I
question it's utility, especially if people now think they have to use
it or
they can't model a building. Friendly front ends like eQUEST,
DesignBuilder,
etc., are great but you need to know how a building operates and how the
systems work or it's just GIGO.

I haven't had much luck with customizing spaces either. 

I think there is a way to import a revit model file into equest.  If I
needed complicated zones & spatial geometry, I would probably consider a
revit license, but with that come's more money ($4-$6k for 1 standalone
license) and possibly more training, but might save a whole lot of
headache.



Seems like equest is more of an energy modeler than an accurate building
modeler.

Dear all,

Once again, another problem!

I have several spaces which were geometrically modified in the design.
For
example, a room that was split into two different ones; with each room
being
a different hvac zone. How can I possibly split a room into two zones
"1"
and "2"? Shall I modify the geometry of the old zone to be that of zone
"1",
and then add another zone "2" from scratch? If this is what should be
done,
how can I do this accurately?

Attached is the polygon view of one of my floors. When you look at them
in
2-D or 3-D views, the building seems perfect in shape. Notice the
rectangle
to the left of the picture! This is actually a zone that lies inside the
building. But it appears like this in polygon view. I think it is some
problem of coordinate references or so!
So when I need to modify the geometry according to coordinates of
vertices,
I'm suffering!

Many thanks!
Omar
