</div>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have a large 4 story building that i am modeling that is
about 50 % lab space set to 12 ACH and 100% OA and constant volume. I
have created a parametric run to turn down to 6 ACH and i am getting the same
CFM and utility bill information. Is there something i might be missing
as an input to either the model or the parametric run?<br>
<br>
any help is greatly appreciated,<br clear=all>
