Smart Staircase Lighting in Apartment Buildings

Why?

To save energy.

How?

Have sensors that “follow” people and where they are in the building, and only turn on the light where they are and the immediate surroundings. Can also be smart and predict ahead, for instance when someone enters the elevator and pushes a floor button, the system can predict when he’ll arrive and light up the corridor a bit in advance. All the time monitoring all corridors and elevator behavior to optimize for all data gathered.
