Energy Saving Ideas

We are making lighting and plug points in an office environment smart and controllable.

The reason is to figure out ways to reduce energy savings.

The one idea we are playing with is having a presence sensor in all the offices so that it can have the lights on when someone is in the room and immediately turn lights off when dormant. Still have not found a feasible presence sensor that would be good enough for this exercise, any thoughts?

Please give thoughts on any ideas how smart lighting and plugs can reduce energy costs.


Lutron has done a lot of work in that space.  I have two of their occupancy sensors, and they work very well.
