Dimming strategies for open office lighting : User experience and acceptance [PDF]

, 2018
Sensor-triggered control strategies can limit the energy consumption of lighting by considering the presence of users in the office and dimming lighting down when it is not needed. In multi-user offices, the application of occupancy-based dimming at room
