Green LEAF

to reduce Energy Consumption

Studies show that energy saving up to

25% can be reached when the room

user considering energy efficiency

Feed back to room occupant on

energy consumption

room runs energy optimized

potential for savings

Room occupant pushes red leaf

room is set to optimized

consumption

Involve the room user in the energy

Groups are used to control related equipment within a room, space, floor or building.

- A single switch can control a group of lights

- A single occupancy sensor can influence several spaces

- An entire façade can be controlled with a single command.

Grouping

Grouping of Occupancy Zones Grouping for Light Control Grouping for Blind Control
