In my opinion, it should not be modeled in the baseline building and outdoor air should be added to the systems. <br>Carol<br><br><div class="gmail_quote">On Thu, Apr 22, 2010 at 8:11 AM, Seth P. Spangler <span dir="ltr"><<a href="mailto:sspangle@rmf.com">sspangle@rmf.com</a>></span> wrote:<br>

<p class="MsoNormal"><span style="font-size: 10pt;">For
the majority of the LEED projects I work on I decouple the space load from the ventilation
load by using a dedicated outdoor air unit (DAOU). Before GBCI took over the
review process the proposed and baseline models contained the same number of
systems meaning if we used a DOAU in the proposed model - we modeled the
same unit in the baseline. I recently received a comment to remove the DOAU
from the baseline and add the ventilation air to the space load systems. For
that particular model it didn’t have a very big impact so I didn’t think
twice about it.</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">The
question – should a DOAU be modeled in the baseline case or should the
outdoor air load be added to the mechanical systems that take care of the space
load?</span></p>
