[Equest-users] LEED EA comments about Model Area and the architecture GFA

[RobertWichert]

Ouch.

I have had these comments before.  They want them to match.  The easiest 
thing would be for the Architect to change their numbers, but they are 
not going to like that.

Have you identified a particular area that doesn't match?  It may be 
only 3%, and you could argue that, but the ANSI standard for building 
area that we are asked to use for homes says within 1 sq. ft. and that's 
way less than one percent.

I'd say it's worth submitting the question to USGBC.

Actually, 40,000 sq. ft. shouldn't be hard to find... Where is it?
