MOVE-energy SAVER : automatic load shedding with integrated presence sensors
Energy savings of up 50% can be achieved through intelligent energy management with building systems technology.
A sensor integrated in an office chair allows light, air conditioning/ventilation, heating and electricity to be controlled efficiently and switched on and off depending on how the room is being used. As a result, energy costs can be cut without having to pay high acquisition costs.
Example: Load shedding for a 10-person office (1 x desk island for 2 persons, 2 x desk islands for 4 persons)
