<span style="font-size:11.5pt;font-family:"Calibri",sans-serif;color:#444444">If you followed the manual for BOTH the proposed and baseline and implemented the same std 62.1 parameters in both, ironically, that's what should happen i. The critical ventilation
changes as a result of the alterations in the baseline's envelope and internal loads. This of course impacts the total system ventilation. <o:p></o:p></span></p>
<p style="mso-margin-top-alt:0in;margin-right:0in;margin-bottom:16.2pt;margin-left:0in;line-height:15.95pt">
<span style="font-size:11.5pt;font-family:"Calibri",sans-serif;color:#444444">Most likely, you want to 1) ensure that your proposed ventilation matches the design ventilation (which should match with std 62)<o:p></o:p></span></p>
<p style="mso-margin-top-alt:0in;margin-right:0in;margin-bottom:16.2pt;margin-left:0in;line-height:15.95pt">
<span style="font-size:11.5pt;font-family:"Calibri",sans-serif;color:#444444">2) set room by room ventilation in the baseline to match exactly with the room ventilations of the proposed. I am pretty sure TRACE does this when you select "New ASHRAE 90.1 baseline"<br>
<br>
Of course, I'm just guessing on your baseline setup, <br>

<p class="MsoNormal">Hi.<br>
<br>
I am modelling a VAV systems in base line and proposed models for LEED certification purpose. Even though I followed the Trace 700 user manual steps for introducing 62.1 air flows I don't get the same Nom Vent in the system check sums report for the baseline
and proposed system?.<br>
