<div class="moz-cite-prefix">Has anyone been able to capture savings
from a natural ventilation design for LEED 2009 NC? (I interpret
that G3.1.1.b prevents this.)<br>
<br>
Glancing over Appendix G I see something that doesn't seem very
encouraging of 'green' design: (not to say that it discourages) <br>
<ul>
<li>G3.1.1.b says, "All conditioned spaces in the proposed
design shall be simulated as being both heated and cooled even
if no heating or cooling system is to be installed ..."</li>
</ul>
<p>It seems like there should be some way to encourage natural
ventilation design by accounting for the energy savings. <br>
I suspect I'll approach this by setting a high Tstat value (100
F) and using the exact same cooling configuration for proposed
and baseline so the savings are null. Well, maybe I can get some
fan power savings.<br>

<div class="moz-cite-prefix">I would certainly bring it up. I
would expect it to be more comfortable and with much lower fuel
costs. Even first cost could be lower, if you really plan to
heat all that air, unless the insulation is very heavy, even on
the roof. I would think you could get away with minimal
insulation on the roof if you used radiant.<br>
<br>
Just my first thought though, I'm sure there is much more to
consider.<br>

Maybe you could keep us apprised of your progress...<br>

<p class="MsoNormal">Hello all,<br>
<br>
I'm working on an 150,000 sf indoor practice facility
with 90 ft ceilings. Does anyone have any
suggestions/tips/heads-up comments that would be
useful in starting this model?<br>
Specifically, I'm wondering if I'll run into issues
related to stratification and need to create
'sub-zones' so eQuest better represents the proposed
distribution system.<br>
<br>
Thank you for your time and combined insight,<br>
