[Equest-users] Modifying Geometry

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,
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!

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.

Wow - I think I struck a nerve.
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
