http://www.tjkeller.net/ but it doesn't mention anything about this system. Most of the energy savings described can be accomplished using off the shelf home automation products like motion sensor, dimmer, and timer switches for lights, and timer-controlled thermostats.
Of course it doesn't say anything about the system. I am not going to give away enough information to allow any decent electronics/embedded systems engineer to recreate it from my description.
Ifg you or anyone else is interested enough, and serious enough, to sign an NDA< I will be glad to reveal the ideas behind the design.
