Bi-level switching is of course not new but research tends to support it as a rather simple, basic but working energy conservation tool in its own right (not to mention it being mandatory in IECC). One study by ADM Associates showed energy savings of 22% (if my memory serves me) in private offices. Overall, bi-level switching is simply another tool that has its applications. What's really interesting is a recent CLTC study combining bi-level switching and occupancy sensing in private offices, which showed that combing bi-level switching and a manual-ON occupancy sensor generated 46% more energy savings than if an occupancy sensor was used alone.

In fact various studies have shown in the "real world" that instructors and students tend to hit all the switches for they do not know or care which one lights what. Please keep that in mind, the rest of your study is plausible but bi-level is not a energy conservation tool!
