you followed the manual for BOTH the proposed and baseline

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>

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

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>
