is your building single story or multiple story? 40,000 sf is a
huge difference. two things i would check first are:<br>
<br>
1. are parts of the building, in the architectural square footage,
exterior? i.e the 1st floor plan sf the architect is using has
canopy area, or is there a walkway under part(s) of the building if
it is multistory?<br>
<br>
where did the architect get the sf number they are using? and how
does it impact calculations in other points?<br>
<br>
2. does part of the building have plenums? plenum zones in the
sv-a reports will show up in the area sf so if you have a vertical
building & some floors have plenums while others don't this can
skew the sf on the sv-a reports though not on the sf reported as the
building/floor footprints. <br>

<p class="MsoNormal">I got a LEED EA Cr1 review comment from
GBCI. <o:p></o:p></p>
<p class="MsoNormal">It’s about the model area and architecture
Gross square footage. The total building area in the
simulation report is 1,121,319.6 square feet and the area in
architecture documents is 1,161,727.32 square feet. The
comments said that the area value in the model should be
consistent with all other credits and LEED online and/or
provide a supplemental narrative explaining the discrepancy.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As a energy modeller I think all of you
know that the area in the model could not be easily consistent
with the architecture CAD drawings. Although In the footprint
drawing stage I was very care about each floor’ area(because I
understand the area in the model should be consistent with CAD
drawings especially when it was for a LEED model), it still
results discrepancy in the two area values.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now the difference about the two area
values is about 40407.4 sqft (3754sqm), and it is only 3% of
the total area. It’s hard to revise the model in this stage,
but what I should do to explain the discrepancy. Does anybody
here have experience to deal with this problem? And do you
know how much difference (%) could be accepted by the review
team?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for your attention.<o:p></o:p></p>
