</font></div><div><font face="comic sans ms,sans-serif">Because DCV can modify OA volume by the number of people in zone, and the OA requirement is dynamics in simulation - which is too hard to keep baseline same with, and also should not keep the same, if not where does the saving come from?<br>

<p class="MsoNormal" style="margin-left:.5in">G3.1.2.5 states that minimum ventilation rates will be
the same for proposed building and baseline building. Does it mean that if
my building design OA rate is increased by 30%, my model will still be
based on the minimum OA required by 62.1 and is still equal to the baseline
building OA? Meaning my proposed building wont be penalized by supplying more
OA?</p>
