The Rise of Sensor-Based Lighting Automation

As building managers look for ways to cut costs and improve occupant experience, intelligent lighting controls are becoming increasingly popular. These systems leverage sensors and wireless connectivity to automatically adjust lighting based on occupancy and daylight levels. According to a recent report by XYZ Research Firm, the global market for intelligent lighting controls will grow from $5 billion in 2020 to over $12 billion by 2025.

Occupancy Sensors Drive Energy Savings

One of the most common types of Intelligent Lighting Controls are occupancy sensors. These passive infrared (PIR) or ultrasonic sensors can detect when a space is occupied and keep the lights on. When the space is vacated, the lights automatically switch off. For low occupancy areas like storage rooms or restrooms, occupancy sensors have been shown to reduce lighting energy consumption by over 50%. Major companies are now mandating the installation of occupancy sensors as part of energy efficiency initiatives.

Daylight Harvesting Maximizes Natural Light

Another useful function of intelligent controls is daylight harvesting. Photosensors monitor ambient light levels and adjust electric lighting accordingly. In areas with ample windows and skylights, daylight harvesting solutions can reduce lighting power by 30-50% on average. The systems pay for themselves within a couple years through energy cost savings. There are also indirect benefits like improved worker productivity from exposure to natural light.
