Overview of Australian Standards for Road Lighting Energy SA Road Lighting for Local Government Forum Overview of Australian Standards for Road Lighting Alec Fisher, Chair of Standards Australia Road Lighting Committee

Basic Principle It is axiomatic that all discussion and decisions about road lighting are based on fulfilling the performance requirements of the Australian / New Zealand Roadlighting Standards AS/NZS 1158 series.

Standards There are long and well established Australian Standards for road-lighting - an important public service Dichotomy of lighting - for traffic routes (for vehicle drivers - high light level - 30% reduction in night road accidents - 1/4 lighting points  1/2 cost) for local roads, paths, public areas (for pedestrians - low light level - safety and security -  3/4 lighting points  1/2 cost) A/NZS 1158 - Part 1.1 Category V lighting 1997 with 5 categories - V3 the norm Part 3.1 Category P lighting 1999 with 5 categories - P5/4 the norm Both V3 and P4/5 are modest lighting levels

How do the Standards Arise? The Committee represents all stakeholders - Standards Aust provide only logistic support Work initiated by outside request and Committee decision Committee drafts, discussion and consensus Use of experience, research and international CIE recommendations Outside input and transparency through public review Regular review, amendment and revision - an evolutionary process

Format of Standards They specify performance in terms of light technical parameters and their values eg. V3 - average carriageway luminance (brightness) - 0.7 cd/m2 Compliance is demonstrated by using specified computer design and documentation All performance values are in-service; initial values will be higher Continuing compliance is assured by a design maintenance regime The designer cannot use a maintenance factor of >0.7 The performance Standards do not refer to equipment but there is on Guide

Lighting Installations Road type, operating characteristics > light level, environmental parameters (control glare, spill and waste light) Cat V - Light carriageway and verge. HPS compromise between efficacy and colour. Semi glare control > economic spacing S/H  5 Cat P - Light whole road reserve. P5 ‘one light on every 2nd pole’ S/H  12 For high risk of crime > high light level S/H  5 40 Watts of fluorescent light on every other pole has never met the Australian Standard All night burning > Benefit - cost positive

Energy Use Minimisation in Road Lighting Design choose appropriate lighting category > client/designer involvement design to minimum L requirements design to minimise energy use, purchase on system basis Luminaire highest DLOR and IP rating (maintenance factor) Lamp and Control Gear highest efficacy (not LPS) compatible with operational needs optimise lamp wattage in design Cat. V - HPS norm but MH city centres Cat. P - use white light in P4/5 (eye sensitivity) - 80W HPM replacing fluoro (passes Standard) - better use high efficacy Fluoro in high DLOR luminaire as it becomes available Maintenance minimise compatible with in-service requirements of Standard and max MF 0.7 and lamp life
