<p class=MsoNormal>Just going through table 6.4 in ASHRAE 62.1-2007 it looks
like the minimum exhaust rates for labs (educational science laboratories) is 1
cfm/ft2. That amounts to an ACH of 6 (for a 10ft ceiling) and 6.7 for a 9ft
ceiling. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Am I interpreting that correctly? Does that mean for LEED
projects we cannot go below 6 – 7 ACH? Is there a way around it?<o:p></o:p></p>
