Street and Other Outdoor Includes:

Street & Roadway

Outdoor Parking Areas

Safety & Security Lighting

Signs & Signals

Buildings & Decorative

Sports & Recreational

Outdoor Lighting Energy Use:*

  • 8% of the energy used for all lighting
  • 58,000+ GWh/year
  • 93% (of the 8%) Energy Use = Roadway & Parking Area
  • 85%+ Use HID or Other Efficient Light Sources
    • 60% High Pressure Sodium
    • 20% Mercury
    • 5% Metal Halide
    • 4% Incandescent
    • 10% Low Pressure Sodium, Fluorescent & Other
  • 60 Million “Cobra-Head” Luminaires
  • *U.S. DOE. Lighting Market Characterization Vol.1 National Lighting Inventory and Energy Consumption Estimate 9/02
slide4

Why Now?:

  • 1/1/08 – Mercury Ballasts Obsolete (2005 EPACT)
  • Lighting “Zones” Being Adopted – CA and Elsewhere – Light Levels Based Upon Population Density
  • HID Headlights 2000 Lumen (Halogen)  4000 Lumen (HID) = Which Roadways Should Be Lighted?
  • FHWA Now Doing All Roadway Visibility Research With Headlights. Lighting Recommendation Changes?
  • Growing Sensitivity To Environmental Impact, Glare, Stray And Wasted Light
  • Solid State Lighting Systems – “LED Cities”

outdoor lighting environmental considerations
Outdoor Lighting – Environmental Considerations
  • Chicago Skyline – Same Night

Before 11:00 p.m. After 11:00 p.m.

Results: - Bird mortality cut by 80%

- 10,000 bird deaths avoided/year

- Program now expanded to New York, Toronto and other cities

slide23

Outdoor Lighting – Environmental Considerations

CIE 150:2003 includes recognition of the implications of light on animals and plants

First compilation of research information on plants and animals - useful for lighting design

Helpful for understanding the wavelength (color) aspects of environmental lighting

slide24
Street & Other Outdoor Lighting
  • What Are The Energy Saving Opportunities?
  • Other Benefits – Quality, Lower Costs ….
  • What Kind of Programs Make Sense
    • Mercury Luminaire Replacement
    • LED Streetlight Test
  • How Should Environmental Concerns Be Included?
slide25
Street & Other Outdoor Lighting
  • What Are The Energy Saving Opportunities?
  • Other Benefits – Quality, Lower Costs ….
  • What Kind of Programs Make Sense
    • For Example, Mercury Luminaire Replacement
  • How Should Environmental Concerns Be Included?

Because Of The Fast-Changing Technology,

This is A Good Time To Address The Issues.
