style='font-size:10.0pt'>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><o:p></o:p></p>
