7

• The first electric public light was installed
  116 years ago.
• 1.94 million public lights in Australia
• 30 per cent major roads
• 70 per cent minor roads.

8

• Annual cost to customers of 210 million per
  year.
• Public lighting is single largest source of local
  governments greenhouse gas emissions, accounting
  for 30 50 per cent of their emissions.

9

• National greenhouse gas emissions of 1.15
  million tonnes of CO2e per year, or
• 0.5 per cent of stationary energy emissions
• 0.2 per cent of national emissions.
• Equivalent to the greenhouse gas emissions from
  77,000 households.

• Information to assist local governments to
• improve public lighting of minor roads in their
  communities and reduce their greenhouse gas
  emissions
• lower their costs
• decrease their liability and risk.

Case Studies

• Coffs Harbour
• SSROC
• CVGA
• Hepburn Shire Council
• Midvale, Mosman Park and Subiaco

13
Coffs Harbour

• Mercury vapour lamps phased out and replaced with
  50 Watt High Pressure Sodium lights in
  residential areas.
• Higher quality lighting and greater reliability
  resulted from new luminaire design, with more
  reliable photoelectric cells and reduced lumen
  depreciation.
• Community survey revealed a high level of
  acceptance.
• Modelling showed possible cost savings of
  691,000 in the first 10 years.

14
SSROC

• Mercury vapour lamps replaced with metal halide
  retrofit lamps on main roads.
• No identified failures or other technical issues.
  
• Improved lighting in high profile commercial and
  entertainment precinct and areas at risk of crime
  with minimal capital cost, disruption or delay.
• Metal halide - superior colour rendition -
  strongly favoured in higher risk areas and is
  suitable for use with CCTV.

15
CVGA

• 14 LGAs collectively negotiate with distributor
  (Powercor) for the provision of energy efficient
  street lighting and to reduce their greenhouse
  emissions.
• Target greenhouse reductions 30 per cent below
  2000 levels.
• Strategies
• Turning lights off or dimming them at certain
  times of the night.
• Close monitoring of the performance and cost of
  lighting system trials.
• More energy efficient street lights on Category V
  and P roads.
• Long life Electronic Photocells to reduce
  Dayburners and Drift.

16
Hepburn Shire Council

• Mercury vapour lamps are being replaced by T5
  fluorescent lights.
• Trentham experiences very cold winters.
• Trial continues.

17
Midvale, Mosman Park and Subiaco

• WA LGA, State Govt and Sage Consulting Engineers
  conducted a project in three suburbs.
• Monitoring both greenhouse gas emissions and
  community security.
• Final Workshop in 2007.

Downloadable Calculator

• Prepared for the Australian Greenhouse Office by
  
• Environmental Edge Consulting and Genesis
  Automation, with the assistance of Sustainable
  Energy Authority Victoria, Northern Greenhouse
  Alliance Victoria, and ICLEI Local Governments
  for Sustainability.
• Parameters for the Model were the subject of a
  workshop in Melbourne late 2005.

National Sustainable Public Lighting Webhub

• Funding from the Australian Government to expand
  the Victorian Sustainable Public Lighting
  Information Hub to a National Sustainable Public
  Lighting Webhub.
• Delivered ICLEI Local Governments for
  Sustainability Australia/NZ.
• One-stop-shop for local governments across
