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
Lighting Controls – The Past
 On / Off Control
 Breakers & Switches
 Time Clocks
 Photo & Motion Sensors
 Dimming Control
 Incandescent
 Fluorescent
Expensive

Advanced Lighting Control – The Future
 Components – The Stuff We Don’t See
 Lighting Control Panels
 Smart Breakers / Power Panels
 PCs
 Software
 Control / Communication Networks

Advanced Lighting Control - Benefits
 Basic Benefits
 Improved Light Levels
 kW Demand Reduction
 kWh Savings
 Reduced Air Conditioning Load
 Lumen Management
Lamp Depreciation

Adaptive Space Usage
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
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
Energy Savings – Where are the Opportunities?

Energy Savings – Where are the Opportunities?
 Environmental Savings
 Carbon Reductions
 Reduced Foreign Oil Dependence
 Eliminate or Reduce Toxic Compounds

Existing Electric Infrastructure Relief
Reduced Light Pollution & Trespass
Improved / Restored Wildlife Habitats
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
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.
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
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
