<div class="yiv8639181209MsoNormal"><span style="font-size:11.0pt;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.</span></div>

<div class="yiv8639181209MsoNormal"><span style="color:black;">from Conduction Losses and not from Ventilation using Outdoor Air. This is confusing </span></div>

<div class="yiv8639181209MsoNormal"><span style="color:black;">to us, since the SV-A Report in the DOE-2 Engine reports shows Outdoor Air in the system results.</span></div>
