Lighting Control Strategies
• Scheduling • Occupancy Sensing • Daylight Harvesting • Personal Controls • Demand Response • Tuning • Real-time Pricing • Scene Controls • Lumen Maintenance
2009 CAMPUS LIGHTING RETROFIT FORUM
Digital Lighting Controls
• Digitally Addressable Controls Components – Sensors, Ballasts, Switches, Dimmers, …
• Digital Wired and/or Wireless Communication
– Targeted Communications through Messages
• Smart Controls Components
– Software based Adjustable & Re-configurable Algorithms
• Smart overall control system – Software based, Unlimited Reconfiguration
2009 CAMPUS LIGHTING RETROFIT FORUM
Digital Lighting Controls Benefits
• Simplified Physical Setup – Wired in Series and/or Wireless
• Unlimited Control Capabilities – Customized Control Strategies & Algorithms
• Multiple Inputs – Sensors, Communications, Occupants, Facility Managers
• Multiple Outputs – Automated Lighting, Window/Skylight & HVAC Controls
– Automated Status & Diagnostic Messages
2009 CAMPUS LIGHTING RETROFIT FORUM
Traditional & Emerging Technologies
• Traditional Control Technologies – Limited number of inputs – Fixed algorithms embedded in controllers – Hardware control for key control parameters
• Emerging Control Technologies – Unlimited number of inputs – Customized algorithms through software – Software control for all control parameters – Dynamic strategies & re-configurability – Monitored-based commissioning
2009 CAMPUS LIGHTING RETROFIT FORUM
Traditional & Emerging Sequences
• Traditional Sequence (front loaded) – Complete control strategy and design up front – Install controls components – Physically connect components to implement design – Commission system to ensure proper operation
• Emerging Sequence (end loaded) – Install controls components in series – Design & implement control strategies – Monitored-based commissioning
• Adjust and fine-tune implementation • Design and implement new strategies
2009 CAMPUS LIGHTING RETROFIT FORUM
Traditional Commissioning Tasks
• Verify placement of components
• Verify physical connections
• Verify Operation
• Fine-tune operation
2009 CAMPUS LIGHTING RETROFIT FORUM
Emerging Commissioning Tasks
• Software-based Setup
• Customized Control Strategies
• Customized Control Algorithms
• Software-based Monitoring & Diagnostics
• Remote, Web-based Commissioning
• Reconfiguration of Strategies & Algorithms

Open Digital Communication Protocol
• Interoperability of controls components from different manufacturers
• Developed by NEMA (NEMA Standards Publication 243-2005) • Wide manufacturer participation • Open-source commissioning software
NEMA 243
2009 CAMPUS LIGHTING RETROFIT FORUM
Controls and sensors are currently operating with an external gateway. Once the new NEMA protocol is approved, DALI controls and sensors will be fully integrated and the need for the gateway will disappear.
