Richard,<br><br>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.<br>
<br>Carol<br><br>PS if you sent two exposures we could probably say more.<br><br><div class="gmail_quote">

<p class="MsoNormal">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?!</p>
