<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial Narrow","sans-serif";color:#1F497D">Another way I guess would be to subtract the space loads from the system loads – which would in theory get you the ventilation loads. This won’t actually
tell you how much energy is being used to meet that load though. Much simpler to zero out the OA.

<p class="MsoNormal">Hi Dave, I use the quick and dirty way for peak vent loads from the SV-A report using the multiplier of the supply cfm and the OA% values at the top of the report. You can also compare the peak Vent CFM at the zone level at the bottom
of the report where they show the OA CFM for each zone.<o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I was wondering if there is a quick way to determine how much of the projected energy use in a building is due to conditioning of ventilation air? I have scoured through the
eQuest reports and detailed simulation output but no luck (unless I’m missing something). I suppose I can run the simulation again with ventilation set to zero, but it would be great if it could be drawn straight from the simulation output.<o:p></o:p></span></p>
