<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Small rotational differences are typical of buildings with similar
surface areas on the east, west, north, and south elevations.  I would
only expect a significant difference if you have a very “long”
footprint, or one side of your building is largely unconditioned along the
perimeter.  Conceptually, I suppose we’re being “rewarded”
for choosing an optimal orientation rotation on the building site – but
if anything we’re really being rewarded for designing “long”
building footprints as they can have a larger difference against the averaged
baseline…<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>That said, if an architect asks me at a conceptual design stage,
the most thermally efficient building shape considering exterior surface area
is theoretically a hemisphere - barring that a “cubic,” compact 3D
shape is better than any “long” shape with larger surface area for
the given volume/footprint.  If the goal is to maximize LEED points
(relative baseline performance), you might suggest a thermally inefficient, but
optimally-oriented “long” shape that will do better than it’s
averaged baseline… (I wouldn’t!)  If the goal is to reduce
energy consumption/utilities however for the end-users, reduce the building shape
surface area.<o:p></o:p></span></p>
