the heat (cool) delivery was to be placed there. I think reality is more complex; heat (cool) distribution being the real concern, I think it comes down to how well the heat (cool) gets around the space. Perhaps a ceiling fan, or a Big A$$ fan could take
care of that better than the registers at the windows.<o:p></o:p></span></p>

<p class="MsoNormal">can you take advantage of the coanda effect, in which a stream of air enjoys scurrying along a flat surface? If so, yes, shorten duct runs accordingly. And maybe reduce fan size, too, if you're reduced enough static pressure.<br>
