Gregg.,
The 3va per square foot that been written in NEC code cycle for super long time I don't really recall when the last time they change that and I have a funny feeling with engery pact they are tighen up the " noose " on genral lighting circuits.
I know in france it is 1.5 to 2 watts per sqfoot { I did converted from sqm² to sqfoot } they change that requirement about 10 years ago
Merci,Marc
