[Greenbuilding] lighting

I often use a similar "trick." Instead of installing expensive 
dimmable CFL recessed lights, I divide the lights up into two switch 
legs so that either one or both of the circuits can be turned on. A 
recent example was in a skylighted kitchen, where the switches 
basically served as a manual daylight harvesting control: half the 
lights were used when needed during the day, and all were usually 
used at night.

We also had lights up in the skylight wells, so there was actually a 
third variable in the artificial lighting level.
