Emerging Lighting Technologies Roundup

1. Emerging Lighting Technologies Roundup Advanced Whole Building Lighting Controls (…think BMS !) Presented by: MEG control Products

2. Why are Lighting Controls Important? • Lighting is the largest consumer of electricity • kWh Usage Savings • kW Demand Savings • Quality of Work Life • Over-lit • Under-lit • Environmental • Light Pollution and Trespass • Wildlife Habitat Destruction

3. Lighting Controls – The Past • On / Off Control • Breakers & Switches • Time Clocks • Photo & Motion Sensors • Dimming Control • Incandescent • Fluorescent • Expensive • Didn’t work so well

4. Advanced Lighting Control – The Future • Components – The Stuff We See • Light Drivers (Dimming or Daylight Harvesting Ballasts) • Lamp Selection – Consider Efficacy • Photosensors • Occupancy Sensors • Improved Technology • Improved Application • Smart Fixtures • Integrated Control & Communication • Scene Controllers

5. Advanced Lighting Control – The Future • Components – The Stuff We Don’t See • Lighting Control Panels • Smart Breakers / Power Panels • PCs • Software • Control / Communication Networks • DALI (Digital Addressable Lighting Interface) • 0 to 10 Volt • Wireless (not quite there yet…) • Communication Protocols

7. Advanced Lighting Control - Benefits • Basic Benefits • Improved Light Levels • kW Demand Reduction • kWh Savings • Reduced Air Conditioning Load • Lumen Management • Lamp Depreciation • Fixture (dirt) Depreciation • Adaptive Space Usage

8. Advanced Lighting Control - Benefits • Enhanced Benefits • Time of Use Billing Management • Curtailment / Demand Management • Tax Credits / Deductions • Smart Grid Ready • Program Benefits • Energy Code Compliance • NYSERDA / Agency / Incentive Compliance • LEED Credits

9. Advanced Lighting Control - Obstacles • Cost – Components / Systems are Expensive • State and/or Federal Incentives Available • Tax Benefits can Improve Paybacks • Energy Savings are Significant • Increasing Energy Costs will help Justify • Time of Use Billing savings will get even better • Lack of Knowledge • Available Products and Capabilities • Products are Getting Less Expensive • Implementation can be Challenging • Getting Value out Requires Training

10. Energy Savings – Where are the Opportunities? • Technology Based Savings • Fixtures • Ballasts • Lamps • Reflective Surfaces • Lenses • Sensors • Photosensors • Occupancy Sensors

11. Energy Savings – Where are the Opportunities? • Control Based Savings • Dimming • Light Leveling / Balancing – NOT Daylighting • Scheduling • Occupancy • More Sensors versus Fewer Sensors • Daylight Harvesting • Open Loop versus Closed Loop Strategy

12. Energy Savings – Where are the Opportunities? • Other Savings • Specific Use • Cleaning • Security • Maintenance • Longer Component Life • Reduced Occupant Complaints • Automated Alarming • Associated • Reduced Air Conditioning Load • Improved Personnel Productivity • Reduced Lighting Related Incidents

13. Energy Savings – Where are the Opportunities? • Environmental Savings • Carbon Reductions • Reduced Foreign Oil Dependence • Eliminate or Reduce Toxic Compounds • Mercury in Lamps • PCBs in Ballasts • Existing Electric Infrastructure Relief • Reduced Light Pollution & Trespass • Improved / Restored Wildlife Habitats

14. Energy Savings – What Can We Expect? • 30 % to 70% in Dollar Saving • kW Demand & kWh Usage Savings will vary greatly depending on numerous factors • 2-Year to 5-Year Simple Paybacks • Incentives will improve the Payback Period

15. Office Buildings in 2020 In the future, occupancy sensing carpet tiles will illuminate the path to our desks, to the cafeteria and to the bathrooms. They will control our task lighting, and light a path to the exit in the event of fire or other emergency. We will measure energy usage in watts/person per hour worked.

16. A Case Study Existing Conditions: • Fixtures – 2x4, 3-Lamp, F32, Parabolic • Control – Low Voltage Switches • Quantity – 456 • Run Hours – 6,623 • Annual kWh – 268,788 • Light Levels – 60 to 70 FC

17. A Case Study Proposed Solution: • Clean Fixtures • Install Dimming Ballasts (Light Drivers) • Re-Lamp, new F32 • New Tombstones & Fixture Wiring • Occupancy Sensors • Photosensors • Advanced Lighting Control system

18. A Case Study Project Cost & Savings - Predicted • Technology & Commissioning $ 85,000 • Installation Labor $ 30,000 • Total Project Cost $ 115,000 • kWh Savings 150,145 • Dollar Savings $ 20,420 • Simple Payback 5.6 yrs • kWh Reduction 55.9%

19. A Case Study Project Cost & Payback - Predicted (with National Grid Incentive) • Technology & Commissioning $ 85,000 • Installation Labor $ 30,000 • National Grid Incentive $ 36,715 • Actual Project Cost $ 78,285 • Annual Dollar Savings $ 20,420 • Simple Payback 3.8 yrs

20. A Case Study Project Cost & Savings - Actual • Technology & Commissioning $ 85,000 • Installation Labor $ 30,000 • Total Project Cost $ 115,000 • kWh Savings 182,776 • Dollar Savings $ 24,857 • Simple Payback 4.6 yrs • kWh Reduction 68.0%

21. A Case Study Project Cost & Payback - Actual (with National Grid Incentive) • Technology & Commissioning $ 85,000 • Installation Labor $ 30,000 • National Grid Incentive $ 36,715 • Actual Project Cost $ 78,285 • Annual Dollar Savings $ 24,857 • Simple Payback 3.1 yrs

22. A Case Study Where Were the Savings? Of the total savings… Cleaning the Fixtures 9% Light Balancing (35 FC) 58% Scheduling 16% Occupancy Control 11% Daylight Harvesting 6%
