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:
