<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For medical buildings that are governed by ASHRAE 170 the airflow requirements are a bit different. The standard not only mandates minimum OA flowrates but also general airflow rates (often times 6 ACH or higher). This airflow rate is typically
higher than the autosized rates based on a 20F differential. It seems like the baseline should use the required flowrates like the proposed, but has anyone gone through this with a LEED reviewer. Basically it would mean that the minimum flowrate in the VAV
spaces would be 100% resulting in a lot of reheat energy.<o:p></o:p></p>
