[Equest-users] Use of shells for non-repeating floor shapes

[Richard Williams]

Thanks Carol and Steve,

 

Is it essential to create different shells for each exposure
combination, or just a good idea? I'm worried about ending up with many
dozens of zones. If it is only optional, how else can I get eQuest to
distinguish between internal and external adjacencies? Can it be done
within the overlapping shells, using zones maybe? The attached sketch
may help to explain my question.

 

Thanks again.

 

Richard

Yes to what Steve said too. As you input your polygons check really
closely that your spaces don't overlap and that you selected the right
command for your floors, e;g; on the ground vs exposed to ambient, as
well as your roofs. Specifying your sight coordinates for each shell
from the get go seems to give you control, too. When space walls are off
by even .05 is when you get surprised by an exterior wall where you were
sure you specified an interior one. I have been anal enough to retype my
vertices just to be sure since I'm pretty convinced you can be off by a
bit when you just click on one.

Richard,

I would make a shell for each different exposure. For instance where
your building is exposed to ground versus air, where your building is
exposed to air versus another floor, where it is exposed to a roof
versus air. I would also take into consideration thermal zoning.
Minimizing zones is good but using them to make your life easier is too.

PS if you sent two exposures we could probably say more.

	Dear all

	 

	I am trying to understand how best to minimise use of shells. I
am trying to model a building which has jagged shaped floors which
overlap and cantilever all over the place. The attached sketch is a
simplified section of the building showing how the floors change up the
building. I've reached the conclusion that, although it is undesirable
to have many shells, I will need a shell for each floor. Additionally,
for floors broken into several separate blocks (eg level 1 on the
attached) I will need a shell for each block. Please let me know if I am
missing something?!

	 

	Regards
