<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">For a LEED Baseline, you should have no reason to select “Outside Air From System”. Presumably, you have already completed your Proposed model, and it is running
well with the desired OA amounts specified for each zone. Just copy the OA amounts from your Proposed model zones into the corresponding zones of your Baseline. Check your SV-A reports in the SIM file to verify that the OA is correct at the zone and system
levels. There are no standard reports that show ventilation loads AFAIK. You can create custom hourly reports to track system supply CFM and %OA.<o:p></o:p></span></p>
