<p class="MsoNormal">Put another way:<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">If you have a perfectly circular floorplate, ASHRAE wants you to model an octagon, with respect to a minimum number of facets.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">This specific query reminds me: There was a pretty interesting thought-study presented at ASHRAE’s energy conference in 2015 where someone tested this logic, by asking the question (paraphrasing) “how few facets can we get away with and
still accurately represent a perfect circle?” I don’t recall exactly the answer but the results surprised me with how far you could go in simplifying the shape & still maintain relative accuracy. I believe a 4 sided square (corrected geometrically for volume)
in fact performed very closely to the baseline.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">If you’re sincerely & specifically interested in modeling an octagon as a square, I think you’ll find that could actually be pretty accurate so long as you are correcting for conditioned volume / exposed area. I’d seek out that actual
paper/presentation while you’re at it ;-).<o:p></o:p></p>
