<DIV></DIV>You are fortunate that the explanation worked. I used a very
similarly worded explanation for a project I submitted and the reviewer didn't
go for it. "Inconsistency" seems to be the keyword for the review
process.<BR><BR>At 03:31 PM 8/21/2009, James V. Dirkes II, PE wrote:<BR>

<DD><FONT size=2 face="Helvetica, Helvetica">Hi All,<BR><BR>
<DD>I'm working up a detailed breakdown for process loads in a LEED model,
to justify using less than 25% of total. I'm wondering what other people
have gotten down to. If you've submitted with lower than 25%, how low did
you get, and how detailed was your analysis supporting it? I've got
computers and other electronic equipment, task lighting, and I'm working
on the elevator. Anything I'm missing? The building is ~50,000 sf, mostly
office, but also a workout area (I'm accounting for treadmills but nothing
else draws any power).<BR><BR>
