from your wording of "independent" it sounds like you may have an
application where you have a unit in the proposed building that is
required but not provided in the design? or something similar. is
this the case? if a unit is required in the proposed per the
requirement all spaces be heated/cooled (per the definitions) they are
required to be the same as the units in the baseline building. if this
is not the case if you post the exact comment it may shed some light on
the subject. otherwise i would argue the comment is in error - if all
of your zones are served by units in the proposed and you have matching
units in the baseline (regardless of system types) then your approach
would be correct. <br>

<p class="MsoNormal">I recently received comments back from LEED and
one of them was about my fan power. In the submission I calculated all
of my fan power using G3.1.2.9 for the baseline building, and I used
the actual fan power in the proposed building. The reviewer has
commented that all independent fan systems have to be modeled
identically in both the baseline and the proposed building. The supply
fans use very high efficiency motors, and as such are substantially
more efficient than the calculation that G3.1.2.9 provides. Is there
no way to take credit for using high efficiency supply fans?<o:p></o:p></p>
