<p><font size="2">Sam,</font><br>
<font size="2">We've been modeling many complex / unusual situations like yours. In some models our efficiencies come out great (high 30%s). Of course after looking for CIRs, just put together all your documentation, wrap it up and send it to the USGBC (it seemed like you were describing a LEED project). You'll have two reviews, a design review after which you can answer questions / modify design, and then a construction review. Key is to describe any and every question you think they can ask you about the design and be sure to write narratives in a manner that a person that doesn't know the project can understand. </font><br>
<br>
<font size="2">Additionally there's a section in 90.1 section 2.5, "This standard shall not be used to circumvent any safety, health, or environmental requirements." and 62.1's section 2.1 "This standard applies to all indoor or enclosed spaces that people may occupy, except where other applicable standards and requirements dictate larger amounts of ventilation than this standard..." </font><br>
<font size="2">I believe the ventilation rates are to be kept the same in 90.1 for breathing, building wash-out, and of course energy. I would think safety would take precedence over these factors when your trying to compare apples to apples. </font><br>
<br>
<font size="2">What do you others think? </font><br>
