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

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?

Technology Based Savings

Fixtures

Ballasts

Lamps

Reflective Surfaces

Lenses

Sensors

Photosensors

Occupancy Sensors

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

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

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

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.
