OverView: Control lighting intelligently for energy savings and comfort by integrating sensors (occupancy, daylight) and automated logic, adjusting lights based on real-time data like time of day or natural light (daylight harvesting). This provides dynamic control, optimizing illumination, reducing waste, improving productivity, and enabling remote management, moving beyond simple scheduling to data-driven efficiency and enhanced user experience. 

Key Functions & Technologies

  • Occupancy Sensing: Lights automatically turn on/off or dim when areas are occupied or vacant, using motion sensors.
  • Daylight Harvesting: Sensors measure natural light, and the BAS dims artificial lights to maintain consistent brightness, saving energy.
  • Time Scheduling: Lights follow pre-set schedules for operational hours, with remote override capabilities.
  • Data Integration: Sensors within fixtures (like motion, ambient light) feed data to the BAS, providing insights for better energy management and space utilization.
  • Remote Control: Facility managers can monitor and adjust lighting from smartphones or web apps. 

Benefits in Smart Buildings

  • Energy Efficiency: Significant reduction in energy consumption by eliminating unnecessary lighting.
  • Enhanced Comfort & Productivity: Creates optimal visual environments, improving occupant well-being.
  • Operational Efficiency: Automates tasks, reduces manual intervention, and provides data for smarter decisions.
  • Sustainability: Supports green building certifications (like LEED) by tracking and reducing energy use.
  • Advanced Features: Data from lighting sensors can even help map space usage patterns and pathways. 

How it Works

Integration: Connects with other systems (HVAC, security) for holistic building optimization. 

Data Collection: Sensors (occupancy, light level) and controllers gather real-time data.

Central Processing (BAS): A central system processes this data using pre-set logic or machine learning.

Automated Response: The BAS sends signals to lighting fixtures to adjust dimming, on/off status, or color.
