Contact me via e-mail and I can give you some links for Title 24.

Basically you will need to retain "Bi-Level" switching, which cuts 1/2 the lighting power [half of the total lights per room or area].
This can be done by either using 2 lamp ballasts in each fixture, or creating a "Checkerboard" making every other fixture on the opposite switch. Checkerboard method allows you to use 4 lamp ballasts, but does not end up as uniform as the "A/B Per Fixture" method does.
