LIGHTING 5
• Energy and Greenhouse Gas Savings – A 52 %+ reduction in street lighting energy use and consequent Greenhouse Gas ( GHG ) emissions and a further 10-20 % improvement if smart controls are included .
• Maintenance Savings – A 50 %+ reduction in the street lighting maintenance burden from the greatly improved reliability of LEDs as compared to previous luminaire technologies and through the better asset management capabilities of smart controls .
• Overall Cost Savings – At least a 25 % reduction in total long-term costs for councils and main road authorities from a combination of maintenance and energy savings .
• Safer Roads – A material reduction in road crashes ( and consequent fatalities and serious injuries ) at night by potentially increasing lighting levels that can reduce crashes by as much as 30 %. Widespread use of high quality white LED light with better colour rendition and optical control , together with higher levels of reliability may add further safety benefits .
This could materially contribute to achieving the government ’ s challenging National Road Safety Strategy goals by 2020 .
• Environmental Benefits – The reduction of carbon emissions , elimination of 90kg of the mercury currently used in legacy street lighting lamps , reduced obtrusive light , reduced upward waste light and consequent sky glow , and reduced impacts on Australia ’ s ecology when smart controls are used to better control lighting outputs .
• Facilitating the Smart City – Improvements in the delivery of community services , productivity , disaster resilience and liveability by using street lights as an enabling platform for transmitting community-wide data and establishing connectivity with other devices in the public domain .
• Night-time Enhancement – Enhancing the amenity , ambience , and safety of streets , parks , and the business prospects of entertainment and tourist precincts at night .
