[Equest-users] Modifying Geometry

[Otto Schwieterman]

You can build any roof geometry imaginable. 

 

You must realize that this is time consuming and makes virtually no
difference in the building model results. I would attempt to keep the
roof simple to avoid wasting a lot of time for little to no change in
energy consumption.

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
