Occupancy-Based Lighting Control for Offices
Lights that know when rooms are empty — so you never pay for light that no one is using.
What is Occupancy Lighting?
Occupancy-based lighting uses passive infrared (PIR) and ultrasonic sensors to detect human presence and automatically switch lights on/off. Combined with daylight harvesting, it maximises natural light and minimises artificial light use.
Why you need it
Lighting accounts for 20–30% of commercial building energy costs. Occupancy-based systems with daylight harvesting typically cut this by 40–60%, paying for installation within 2–3 years.

Frequently Asked Questions
We use dual-technology sensors (PIR + ultrasonic) that detect micro-movements — even someone typing at a keyboard. This eliminates 'lights turning off while someone is there' issues common with PIR-only sensors.
