[Equest-users] Shell stacking options

[Bishop, Bill]

Richard,
 
I usually use option 3 - create one shell per floor and add roofs as
necessary wherever the lower floors are exposed. (So create your shell
2/3 as one shell and create a roof(s) above the zones in shell 3.) This
requires copying/modifying polygons, which I find easier to do within
the input files. After you do it a couple times it's not so bad.
 
Regards,
Bill

Hi again
 
A while ago I posted a question about the use of shells and receive some
very useful responses explaining that best practice is to use different
shells for each exposure/adjacency combination. I have a follow up
question to this which is a little tricky to explain but hopefully the
attached will help.
 
The attached shows two shell variants for the same building. The top
floor (shell 1) is smaller than the other floors. Therefore, for both
variants the floor below is broken into two shells; shell 2 which is
exposed to the top floor and shell 3 that has a roof exposed to
atmosphere. My question relates to the floor below these. Can this be
comprised of a single shell which spans both shell 2 and 3 as per option
1, or does it need to be broken into two to match the shells above as
per option 2?
 
Regards
 
Richard

discussion on shading geometry

Hello
 
Is it possible to use non-rectangular polygons as shade? If so how do I
do this?
 
Any suggestions much appreciated.
