Basically they do consider that in that if you want more light you
have to use the most effecient equipment. This is simplified as there
are adders for high ceilings, and you treat rack lighting different.
All though there is whats called the prescriptive method whereas you
can have as many 2/L T8 fixtures as you want. For an office building
it 1.2 watts per square foot.

Sounds like a spec written by the local utility rather than a lighting
systems engineer.
