[Equest-users] Modeling Courtyards

[Nick Caton]

Actually, provided you are eventually going into detailed mode, the
method you're showing (using "cutting walls") can produce fewer
adiabatic walls in the final result.

 

As an extension to this and a response to Otto's concern:  You will want
to delete the two face-to-face exterior walls that will be generated by
your footprint cut.  Doing so will not open the adjacent zones to the
world, but will make those sides have no heat transfer to/from anything.

 

If you build two shells, you will have two sets of "cutting walls,"
where the two shells join.  The wizards can automate making the joining
walls adiabatic, provided your footprint geometries are spot-on, but
ultimately you have two adiabatic breaks in your building with that
approach, whereas with this you have only one.  The other major
advantage is you are minimizing the number of shells with this approach
- very handy when you don't have to manipulate multiple schedules and
such later on.

PS: it seems curious - based on what little I can tell - that you've
defined a custom "zoning pattern" that creates a perimeter zone on both
sides of your shell "cut."  This may be intentional, but I would
intuitively zone those areas to be tied to the core zone.

 

PPS: You may find much further discussion regarding this approach, if
you wish, by searching for the terms "courtyard" and/or "cutting walls"
in the archives.

Alex, 

 

Break the shell into two shells. If you create one shell where the walls
are close but do not touch each other, you will have two exterior walls
where you do not want them.

Hi all,

 

I'm hoping to get some advice on how to model a courtyard. I thought
I've seen some emails floating around about them, but couldn't find
anything in the archives. What's the best way to model a hole in a
building? Any help on this would be much appreciated.

 

 



 

Regards,

Alex Krickx
