We also talk about design issues throughout Article 210 with all of the required circuits so this is not unexplored territory. Backdooring these changes in the energy code only adds to confusion.
I do sympathize with a resi EC that just wants one code book to refer to, but commercial industrial has really expanded way beyond the NEC.
Allot of what a commercial electrical designer/engineer deals with is now in the energy code anyways;
Lighting, transformer efficiency, voltage drop, motor efficiency..
I have to submit compliance with all that stuff.
Then there is all the life safety egress lighting, stand by systems, and fire alarm codes...
ADA height requirements for electrical..
For a typical retail store design I way have more plan checks in other codes than the NEC.
Even something as simple as a E-stop for a gas station is affected by a different code.
The outlet spacing and design stuff for residential in the NEC 210 dates back to the 1930's when people used extension cords tapped off lighting pendants and it was causing fires thus falls in the 90.2 scope.
Just my 2 cents.
