[Equest-users] Modifying Geometry

[Morton, Sarah]

Revit is also very picky.  If the person setting up the architectural model does not set it up with load and energy modeling in mind you will spend a lot of time messing with the architectural model before you even get into the MEP model.  I don't recommend it yet.  Maybe as the design community gets more familiar with Revit and the MEP version becomes more developed it will become a viable option.

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
