A NEW ZEALAND LOCAL GOVERNMENT MAGAZINE SPECIAL SUPPLEMENT

STREET LIGHTING

Stealth LEDOld technology

CosmoPolis

A national leader in

researching and trialling

new sustainability initiatives,

Waitakere City has turned its

attention to new streetlighting

technologies in its search for energy saving

opportunities.

Known nationally and internationally

as New Zealand’s Eco City, Waitakere

has made some good energy efficiency

gains in recent years, winning the EECA

EnergyWise Public Sector Award in 2007

in recognition of its $1.26 million and 8.6

million kWh savings since 2001.

The council acknowledges that it has a real

challenge ahead if it is to reach its goal of

reducing greenhouse gas emissions by 50

per cent by 2021 – a daunting task when

streetlighting comprises 26 per cent of its

total emissions. However, by identifying

energy saving opportunities, Waitakere

has already begun to stabilise its emissions

ahead of target.

Waitakere began looking at energy efficient

opportunities for streetlighting in June

2007 after hearing about a CosmoPolis

street lighting project in a Whangamata

subdivision. A business case was

developed and Waitakere installed 203

of the CosmoPolis new metal halide

lights in the city over last financial year.

The council was also introduced to light

emitting diode (LED) streetlighting

last year when an Auckland company

approached it to install and trial its first

production of the LED lights in Waitakere

– the results of which continue to be

evaluated.

However, the most significant opportunity

for Waitakere to understand the

possibilities for reducing energy usage

(and therefore greenhouse gas emissions)

came from discussions with Modus

Lighting around smart technologies, such

as streetlighting control and dimming

systems.

Waitakere’s corporate sustainability

manager, Michelle Dawson, says energy

efficiency for streetlighting systems poses

a significant challenge for councils, who

inherit most of their new streetlighting

from developers and only replace a small

percentage each year through capital

upgrade programmes.

“As standard lighting infrastructure

equipment, energy-efficient streetlighting

bulbs and luminaires (light fittings) can

provide an energy efficiency gain of 25 to

50 per cent. Around another 35 per cent

of energy reduction can come from smart

control of the streetlighting system itself,

if the technology is installed during a

council’s capital upgrade programme or as

part of new developments,” she says.

“Councils cannot develop the solution

for energy-efficient streetlighting by

themselves. We need to work with the

industry to get some of the technological

solutions into New Zealand and installed.

We also need to look at new opportunities

for funding their installation to reduce the

burden on ratepayers.”

In its search for energy-efficient solutions

to streetlighting, Waitakere realised that

much more information-sharing needed

to take place within the streetlighting

industry if councils are able to take

action to improve the efficiency of their

streetlighting infrastructure. Waitakere

and Modus Lighting felt others could

benefit from their experiences with some

of the new technologies and were keen to

learn about what others were doing as well.

NEW ZEALAND LOCAL GOVERNMENT - SUPPLEMENT2

NEW ZEALAND LOCAL GOVERNMENT

TECHNOLOGY SUPPLEMENT 2008/09STREET LIGHTING

The result was the hugely successful

Advancing New Zealand’s Streetlighting

Technologies Forum and Night Tour, held

in Waitakere on September 24. While

there was an initial expectation of only

30 to 40 participants, the event attracted

more than 120 participants from all over

New Zealand, including government

officials, local government managers,

lighting engineers, urban designers,

developers and lighting suppliers.

The forum began with an informal

trade expo from technology suppliers

exhibiting a range of streetlighting

lamps, control gear and luminaires,

including high-pressure sodium lights,

metal halide lights, solar streetlights

and the new CosmoPolis and LED white

light luminaires. The new generation

luminaires showed the advantages of

precise light-control optics to minimise

spill light and glare and also displayed

much improved weather protection

ratings.

Guest presenters at the forum covered

a diverse range of topics, including

CosmoPolis’ new metal halide, LED

lighting, centralised dimming control

systems, electricity metering for

streetlighting, lighting education,

innovative capital financing techniques

and design consultant viewpoints on

sustainable streetlighting.

The discussion at the end of the

forum considered some of the issues

the industry is facing as it begins to

consider innovative solutions for energy

efficient streetlighting. Some of the

issues raised included opportunities

for capital financing, balancing the

timing of investment outflows with

cost reductions, problematic electricity

tariff structures with high fixed/variable

cost ratios and the current un-metered

electricity supply regime not encouraging

an “invest to save” culture.

The nature of organisational and

financial management within councils

was also cited as a problem, with many

dealing with differing priorities over

short-term cost control and the lifecycle

cost/benefit of new technologies

and the need to identify alternative

funding sources to reduce the cost

to the ratepayer of installing the new

technology.

Forum participants were then taken

on a night tour of Te Atatu Peninsula

to view Waitakere’s installations of

CosmoPolis and LED streetlighting.

This allowed participants to see the

emergent technologies first hand and

compare the nuances of light, colour and

performance. Previously, many had only

seen the technology within their office

environment.

The evening closed with a night

demonstration by Modus Lighting of

an internet-based central streetlight

control and monitoring system. This

demonstration involved using a laptop

computer with mobile internet link to

communicate with a web server (located

in France) to control and measure

light levels and energy usage on a test

streetlight luminaire. This was a mini-

demo of the now-popular European

technique of energy-saving streetlight

dimming during quiet off-peak hours.

The forum participants agreed that some

very basic issues need to be worked

through to enable New Zealand to get

the most out of the new technologies.

This has been heard by the Electricity

Commission and the New Zealand

Lighting Council, who are now

developing plans to support the industry

to begin working through some of the

issues.

In the meantime, Ms Dawson is

encouraging other councils to take up

the challenge of looking for opportunities

to improve the energy efficiency of their

streetlighting infrastructure.

“Not only can we work together to

leverage funding and improve economies

of scale for street lighting products but

we can make significant energy usage

and cost reductions for streetlighting

nationally over the next 10 to 15 years,”

she says.

“In the short-term, there are many areas

councils can begin to work on to improve

the energy efficiency of their street

lighting through capital replacement

programmes and by working with

developers to ensure that they inherit

streetlighting infrastructure that will

meet the needs of the future.

“These technologies will not continue to

develop if we don’t show interest in their

application. For councils, looking at the

capital and operational costs within the

10-year timeframe of our next Long Term

Council Community Plans is a good

starting point.”

The Electricity Commission has

sponsored the production of a DVD

recording of the Advancing New

Zealand’s Street Lighting Technologies

Forum to deliver the message of street

lighting efficiency and performance

improvement to councils and the street

lighting industry. The DVD will be

distributed by Waitakere City Council

and Modus Lighting and is expected to be

released at the end of this month.

NEW ZEALAND LOCAL GOVERNMENT - SUPPLEMENT 3

The conference offered up

pretty much what attendees

had expected to see on arrival.

There were representatives

from some selected luminaire

manufacturers, technology providers

and a large number of attendees from

local councils. After going through

the exhibits and catching up with the

exhibitors, we settled in for an afternoon

of edification and enlightenment (excuse

the pun).

The seminars and trade show in

the main promoted two emerging

lamp technologies –the use of LED

technology, and the new Cosmopolis

lamp produced by Philips. Also

discussed was the use of photovoltaic

cells to provide alternative energy

sources (energy neutral) for road

lighting, using the national grid as the

energy store, the use of technology to

control, meter and monitor the condition

of the road lighting assets and the

need for an alternative funding model

to provide incentive to councils and

road lighting asset owners to use the

new technology. Despite the almost

overpowering swathe of advertising

during these seminars, a number of

issues were brought to light that were

further discussed in an open forum after

the seminars were presented.

New technology and electrical network utilitiesThe most challenging issues for the

industry did not appear to be the cost

of electricity, or a lack of desire to adopt

new technology. The road block to

the adoption of the newer technologies

appears to be linked directly to the cost

of line charges charged by electrical

network utilities, as well as their

apparent lack of flexibility to cope with

un-metered loads that will change their

characteristics (e.g. dimming systems)

throughout their operating period.

When considering this, it is clear that

there is very little financial incentive to

attempt to save power, as, even if one

manages to save up to 50 per cent of

the electricity cost, this only influences

around 5 per cent of ones “power

bill”. This is despite the enthusiastic

encouragement of the various council

energy managers. This issue will

need to be addressed before large

scale energy savings are likely to be

entertained by councils. It is fortunate

that a representative from EECA

attended the conference, and heard these

concerns first hand; and it is hoped that

this issue will be brought before the

politicians and be addressed. While

representatives from the Utilities were

also in attendance, there remains little

incentive for them to address this issue.

Government and the utilities must be

involved to open a dialogue with local

councils and consultants on this matter,

and the conference attendees urged them

to do so.

New LED lamp technology shows promise The new lamp technology presented

was very interesting, with LED’s an

exciting hope for the future. The Philips

Cosmopolis lamp also shows promise

as a technology that could be adopted

by many in the near future. As always,

the information that wasn’t presented

was as interesting as that presented:

lumen depreciation and lifetime figures

for LED’s are still notoriously difficult

to obtain. A number of reputable

manufacturers still comment that LED

technology is changing rapidly, and

that the technology is not suitable for

wholesale introduction and replacement

of the existing lighting stock.

What we felt was equally significant was

the lack of representation of other more

Dark patches emerge in lighting technology

“mature” lamp technologies in the mix.

The CDM-T (and other types of metal

halide lamp) is the poor cousin to

the Cosmopolis in terms of claimed

lamp life and lumen output, but the

technology is supported by more than

one lamp manufacturer, providing a

degree of competition which is not

available with the Cosmopolis. The

use of electronic lamp control gear is a

given on these new lamp technologies,

despite having lower life expectancy

(and therefore higher maintenance cost

to change out – with associated energy

consumption with trucks, and crews

required), than traditional wire wound

though less efficient control gear. While

Beca’s Greg Williams discusses the market readiness of new lighting technology in the wake of the recent Waitakere Street Lighting Conference.



considered “old” technology, the high

pressure sodium lamp remains one

of the most efficient, longer life lamp

sources available, which has significant

reduction in maintenance requirements,

especially in its twin burner version.

Also missing was the compact

fluorescent as a mature, competing lamp

technology.

The evening ended with a tour of

two installations, each one designed

with different “eco friendly” lamp

sources (Cosmopolis and LED). Both

installations provided energy savings

over the lighting that was previously

installed. Of note was the comparison

between the new installation and

the existing one, where the existing

installation was highly likely to be a

non-compliant design. It would have

been interesting to compare the results

with a comparable “current technology”

design. Insufficient and contradictory

information provided about each

installation led us to conclude that

neither were particularly good examples

of a road lighting installation.

The Cosmopolis equipped offering

appeared to be over-lit, and used

luminaires that did not provide adequate

control of light spill into adjacent

properties. Discussion with the designer

revealed that the design was carried

out to meet a category V3 lighting

requirement. There was a degree of

confusion between the designer and the

luminaire supplier on the night as to

whether the specified lamp wattage had

been used.

The LED offering, for a category P3

roadway provided very sharp cut-off.

The light output was so precise that,

as people stepped off the road onto the

footpath outside of the cone of light

from each luminaire, they promptly

disappeared from view. Vertical

illumination was noticeably poor,

and there were also gaps in roadway

illumination where the pole spacing

had been “stretched” to accommodate

driveways. Indeed, the designer advised

the installation would have performed

better if the luminaires had been

mounted 2m higher than they were.

ConclusionSo what did we come away with from the

day’s attendance? Reinforcement of what

we already knew. Yes, we can do a design

if we’ve got all the relevant information

from the manufacturer. And in a number

of instances, Beca is carrying out the

design using this technology. We’ve

found that greater care needs to be taken

with the fine details of the design when

using new technologies, as traditional

light distributions and cut-offs simply do

not exist.

The technology looks to be interesting

and exciting, from a “using new

technology” perspective. It brings

fantastic opportunities and great

potential. It is also really young

technology that needs some more time to

mature. We are advising our clients to

say “yes, this is available, let’s try it”, and

at the same time, to be selective in how

and where the technology is used until it

has been proven; not just from a lighting

perspective, but from the perspective of

standardization and capital, energy and

maintenance costs.

One of the big questions about mercury-based

fluorescent tubes is what to do with them once

they have reached the end of their life.

With a shortage of mercury disposal facilities

in New Zealand and major concerns about the

health risks associated with mercury, a professional recycling

service is required.

Interwaste was established in 2005 and is a locally owned and

run company that specialises in the recycling of fluorescent

lighting.

A major part of Interwaste’s work involves the recycling of

mercury-based products and it is the only company that offers

a zero-to-landfill, 100 per cent recycling service of mercury-

based lighting.

All components of the lamp including aluminium, glass,

mercury and phosphor powder are recovered and recycled into

products that can be reused in a variety of industries.

Mercury is a highly toxic waste contained within all fluorescent

lamps. If disposed of irresponsibly, it pollutes waterways,

damages the environment and can impact on human health.

Interwaste provides a safe disposal option by providing its

customers with lined containers to safely store the lamps

in. This minimises the risk of mercury exposure in the

workplace and ensures companies comply with New Zealand

environmental regulations.

Interwaste’s staff members are trained in all areas of hazardous

waste disposal and take pride in finding cost-effective,

environmentally sustainable methods for disposal of hazardous

waste streams.

The imperative to reduce carbon

emissions is a challenge faced

by all organizations and

individuals. New Zealand has

set a target of carbon neutral

electricity by 2020 and carbon neutral

stationary energy by 2025. The Auckland

Sustainability Framework identifies eight

shifts required to move to a sustainable

Auckland, one of these shifts is to “Build a

carbon neutral future”.

For councils where the lighting of public

spaces and roads typically accounts

for between 30 and 50 per cent of CO2

emissions, there is scope for significant

improvements.

To achieve a zero net carbon streetlighting

infrastructure a sequential approach

is used that prioritises the most cost-

effective measures where energy use is

first reduced and then the remaining

energy consumption is generated from a

renewable source on site.

1. Energy efficient luminaries and lamps

Through the use of modern energy

efficient luminaries and lamps such as

new generation metal halides a 30 per

cent energy saving can be expected.

2. Intelligent lighting control

Intelligent lighting control systems have

a number of advantages, including the

ability to monitor lamp failures and

energy consumption. With respect to

reducing carbon emissions they have

the advantage of allowing the lamp to be

dimmed to the required light level. This

avoids lamp selection for the worst case

after taking into account factors such as

lumen depreciation and soiling which can

potentially result in a more than 120 per

cent oversizing.

A dimming profile can be set for a 24-hour

period, dimming lamps during times of

low pedestrian and vehicular activity. A

typical dimming profile can be expected

to reduce energy consumption annually

by 30 per cent

3. Onsite renewable generation

Through a combination of energy

efficiency and intelligent control, lighting

energy consumption - and therefore

operational carbon emissions - can be

approximately halved. This

SOLAR POWERED STREET LIGHTING

RETRO-BRIGHTour new range of super

bright LED retro fit heads

COMING SOON!

The problem of lighting areas where there is no

access to mains power could be a thing of the past

with a new generation of solar lights hitting the

marketplace.

Kaikoura District Council has just completed

trialling two Solar Stream lights and district planner Matt

Hoggard says the lights have proved to perform differently to

standard streetlights.

“The light spill from them is not as great, so they are really

good in areas where you don’t want a great deal of spill or

especially in areas where there is no access to the mains,” he

says.

Mr Hoggard says that when he checked the lights with a

standard light meter, he got readings of 9.1 lux directly

underneath the solar lights as compared to 8.4 lux directly

underneath a 70W sodium light.

However, at a distance of 10 metres from the light, the reading

was 0.9 lux for the solar light and 1.5 lux for the sodium bulb,

making the solar lights ideal for areas where light is required to

be concentrated on a specific area.

“I think they are ideal for rural junctions, for example, or

where there is a need for low light-spill,” Mr Hoggard says.

“We have an issue here with shearwaters, a sea bird; too much

light spill attracts the birds because they think the road surface

is an area of water, so they land on the roads. Because they are

seabirds, they are unable to get airborne again from the road

surface and many get hit by

traffic.

The lights are based on

simple technology, says

Nicola Martin from Solar

Bright, the company

supplying the lights.

The units consist of a

50-watt LED, a 150-watt

solar panel and two 120

amp-hour batteries buried

in the ground at the base of

the lamps.

“The LEDs drain very little

power, so even when you

get a few very overcast days

in a row the lights still

work,” she says.

The fact that the technology is simple makes it easy to install as

well, which is a plus for councils.”

The trial was a success and the council is keeping the lights.

“There is a lot of public support for solar lighting; people are

comfortable with the idea these days,” Mr Hoggard says.

“I don’t think they will replace standard streetlights just yet,

because the cost is prohibitive at the moment; you’d need a lot

more lights on a street to achieve the same level of lighting.

However, as the technology improves I think that might

change. It’s something we’re going to see more of and I think it’s

a good move to investigate solar lighting.”

A trial of energy efficient street lighting for South

Waikato District Council has shown strong

savings can be achieved by changing from old-

fashioned street lighting to new energy-efficient

models.

The initiative to trial these lights came partly from council

wanting to trial energy-saving measures and from Odyssey

Lighting being keen to test new lights in a real situation.

Standard 150-watt high-pressure sodium (SOM) lights

along Tokoroa’s Bridge Street were replaced by a mixture of

lower wattage SON lamps, 160W metal halide lamps and

Cosmopolis lamps of various strengths.

Early results were impressive, says Odyssey’s David Raven,

although he did point out that not all lights have been

installed and the tested lights hadn’t achieved their full 100

hours bedding-in period when they were tested.

Council officers and Odyssey are also awaiting input from

councillors and police once all of the lights have been fitted.

“We wanted to know could we use the existing infrastructure

and just replace the luminaries, which would make it a much

more viable option for the council,” Mr Raven says.

“We’ve proved that the existing infrastructure can be used

and now we are waiting for feedback from stakeholders on

which sort of light they prefer. We’re also looking to trial LED

Waikato retrofitting trial a success

lights at a later stage to see what the light looks like from those.”

All of the old lighting was replaced with new “regular” lights

prior to trialling the energy-efficient lights so as to ensure that

like was compared with like.

Key points from the initial trial are:

The new energy efficient lights could be retrofitted onto the

existing infrastructure and still achieve cost and energy savings

for council whilst complying to the lighting standard. Bridge

Street in Tokoroa was chosen as it has a central median with

mature trees and this causes irregular spacing of lights. This is

important as it avoids a large capital cost for new infrastructure.

The tested luminaires achieved a 33 per cent energy saving for

the same compliant lighting levels with SON lamps, by replacing

150W lamps with 100W versions and new optics, which

provided the same light at a lower energy cost.

For CBD areas, the tested luminaires achieved a 9 per cent

energy saving with greatly improved lighting levels and whiter

light.

“We still need to carry out a full cost benefit analysis to

determine the payback period and also discuss these new lights

with councillors and police,” Mr Raven says.

The introduction and uptake of new high output ‘sealed’

reflector technology streetlights has been stymied in

New Zealand by a lack of understanding of the new

technology’s benefits. When partnered with a ‘life

cycle cost-benefit’ approach rather than the current

first-cost principle approach to asset purchasing the benefits

become clearly apparent.

The high output reflector has the ability to deliver more light

from the lantern; reduce the amount of light wastage (spill) and

concentrate the light on the road surface where it is required most.

Power Solutions Ltd has discovered that with some new

streetlighting products, by matching a new HID technology

lamp with an optimised reflector it can significantly reduce lamp

wattage, maximise light delivery and reduce energy consumption.

There is also the added benefit of reduced maintenance costs

that the new sealed optic technology brings. This cannot be

ignored and when combined with the energy savings from

reduced wattage lamps a more sustainable, energy efficient and

environmentally friendly streetlighting design can be achieved

by factoring the projected maintenance savings into the life cycle

cost-benefit analysis and achieving significant energy and cost

benefits over the 25-year life cycle of the asset.

Power Solutions Ltd adopts a holistic approach to all designs. This

approach ensures that key asset management fundamentals are

incorporated into every design to optimise the spacings between

luminaires. With the use of electronic software we are able to

assess a number of different manufacturers’ products to ensure

the most economic and sustainable solution is found.

In every design it is of paramount importance to ensure that the

correct road hierarchy is selected. The classification must reflect

both traffic and pedestrian volumes and the individualise by

road demographic to ensure the correct level of light is delivered

to meet the Local Government’s Code of Practice and AS/NZS

1158 suite of standards. Often overlooked in this process is local

government’s intimate knowledge of the area which combined

with the designer’s expertise gives a more appropriate and rational

determination of road hierarchy.

A number of local government clients are currently enjoying the

More than just transit routes, streets are

pedestrian environments, supporting a wide

range of pedestrian uses and activities by all

sectors of society. Urban design principles

have had a significant impact on the design

of the public realm where pedestrian needs and perceptions

are paramount in shaping the urban environment. Lighting

design has progressed from its purely functional role of

meeting predefined lighting standards, to being an integral

part of streetscape and public space design.

A number of considerations that need to be addressed by

urban designers and landscape architects working in the

public realm and incorporating lighting design are discussed

in this article.

Lighting design is fundamental to creating “spaces, places

and transport networks that are safer, with less crime and

fear of crime” (The New Zealand Urban Design Protocol,

2005). It is also important in signalling community

investment and improvement in an area (Welsh and

Farrington, 2007) and is implicit in the Crime Prevention

Lighting up the urban landscapeThrough Environmental Design (CPTED) best practices.

Good lighting placement can overcome compromises in design,

creating safe spaces. Careful placement of lighting fixtures, in

combination with planting and street furniture can generate

safer, and more versatile urban environments. This allows

streets to become activated 24/7, increasing the range of

available activities such as supporting alfresco dining, further

contributing to a vibrant street and city environment and

economy.

In Nuffield Street, Newmarket, Auckland, lighting design

and CPTED principles were used to transform this former

back lane into a lively street precinct. Bars, eateries and retail

boutiques create active edges providing passive surveillance

late into the night. The lighting elements were grouped with

street furniture to reduce kerbside clutter to free up more

usable space.

Lighting is vital in defining a legible pedestrian environment.

The recently completed Beach Road in Auckland’s CBD, the

streetscape lighting upgrade used multi function poles to

lessen street clutter whilst improving visibility at bus stops

and intersections. White (metal halide); reduced-glare lamps,

consistent with Auckland City Council’s lighting policy for

areas of heavy pedestrian traffic were installed to create a

more natural, safer street appearance. An added benefit of the

lamps is that they are energy efficient. The simple, elegant

rhythm of columns along Beach Road, unifies the street, and

differentiates the pedestrian thoroughfare from the built realm.

Appropriate lighting design, can reveal the diversity and

magic of a place. Through the form and composition combined

with careful selection of type and intensity, designers can

skillfully create spaces with ambiance. Specific features can be

highlighted to create a real ‘sense of place’. In Nuffield Street,

up lighters at the base of the street trees and fairy lights within

the trees along with the distinctive façade lighting to create

a magical quality that generates a festive spirit well into the

night.

Street lighting need not be confined to a functional ‘pole’.

Along with street furniture and site specific lighting fixtures,

landscape architects can combine elements to capitalise

on design cues. In Whangaporoa town centre, the striking

slimline street lights are more akin to art form; they

collectively provide a distinctive counterpoint to the adjacent

built form, defining the centre’s identity, and help to integrate

the centre’s disparate buildings. A further example is part of

the realignment of Wellington’s Evans Bay Parade, as part of

Wellington’s urban coastline. The lights, encased in wooden

pillars, make reference to an old graving dock that used to

operate within the bay.

Lighting has a key role in urban design practice; it fulfils the

fundamental personal need to feel safe, while at the same time

reflecting and enhancing the distinctiveness of the urban

environment.

With more than 330,000

street lights in New

Zealand, running

for more than 4000

hours each per year,

streetlighting consumes a significant

amount of electricity. At around $18

million per year this is a major cost for

ratepayers.

The New Zealand Efficient Lighting

Strategy (2008 – 2010) highlights the

significant economic and environmental

gains to be made through the adoption

of more efficient lighting (including

streetlighting) technology. The principal

objective of the Strategy is to “strengthen

naturally occurring, market delivered

efficiency through interventions that

remove barriers to technologically and

economically viable efficient lighting

opportunities”. It identifies the need

to eliminate inefficient street lighting

installations as one of six strategic goals

and sets a pathway to accelerate the

uptake of efficient technology.

With a key role to promote and facilitate

electricity efficiency, and a brief to fund

programmes that provide incentives

for cost-effective electricity efficiency,

the potential savings from efficient

streetlighting is certainly of interest to

the Electricity Commission.

From an investment perspective, the

commission has an obligation to achieve

electricity savings at the least cost, which

means potential streetlighting initiatives

must be ranked against other investment

options such as compact fluorescent

lamps and more efficient halogen lamps.

The extent to which the commission can

commit funding is at a level at which

the resulting energy savings make the

investment economical (i.e. where the

cost of achieving the savings is less

than the cost of building new electricity

generation plant).

Energy-efficient streetlighting

installations have multiple benefits for

councils and communities beyond the

obvious energy, maintenance and cost

savings. These include improved lighting

levels and visibility (which encourages

people to undertake activities at night),

greater safety (through improved

visibility) and reductions in crime.

Although there is significant scope

for local authorities to improve street

lighting efficiency and save money (and

while the other benefits can make it

worthwhile economically and otherwise

for councils to upgrade their networks) a

number of barriers limit the ability to tap

into these savings opportunities.

A Theme Audit of Streetlighting

published by the New Zealand Transport

Agency (NZTA) in 2007 identified some

of these barriers and also recommended

that the NZTA, Local Government New

Zealand (LGNZ) and the commission

to work together to address some of the

issues and barriers identified.

Earlier this year the commission

formed a street lighting working group

including representatives from the New

Zealand Lighting Council, NZTA, LGNZ,

the Energy Efficiency Conservation

Authority, and several councils. This

collaborative approach (which drew

from the outcomes of the NZTA Theme

Audit) has been instrumental in further

defining the operational challenges and

issues facing councils and key barriers to

the uptake of efficient streetlighting, and

identifying initiatives to address those

barriers.

Some of the key barriers identified

include: knowledge of and information on

streetlighting technologies; organisational

structures; split incentives between

developers and councils; procurement/

regulatory policies; stockpiles of low-

efficiency mercury vapour lamps

(encouraged by the retention of like-

for-like replacement policies); tariff

structures; un-metered streetlighting;

existing infrastructure; funding/access

to capital, and a focus on upfront capital

cost. While it is possible to address some

of these barriers (such as information)

through targeted initiatives, others, (such

as tariffs) are structural in nature and

would require a carefully co-ordinated

approach and significant investment of

time and resources to resolve.

Based on the outputs of the street lighting

working group, the commission recently

ran a closed tender for the development

of a comprehensive street

Lighting Council New Zealand is the peak body

of the lighting industry. It was formed in 2003 to

represent the interests of the industry in response

to anticipated changes within the building industry

due to impending revisions of the Building Code and

environmental and sustainability legislation.

New Zealand has a reputation for embracing new technology

and adapting it to suit local conditions. Lighting has been no

exception and over the last 40 or so years the country has been

well served by the industry despite import restrictions that were

lifted only in the last two decades, and the demands made by

what is, in world terms, a very small but relatively sophisticated

market.

As a socially responsible industry we saw the need for this new

technology not only to be encouraged, but encouraged wisely.

Lighting has long been recognised as both a science and an

art and a broad education programme was seen a key to the

future. As a result the industry has for many years supported an

internationally recognised professional education programme

conducted under the auspices of the Illuminating Engineering

Society of Australia and New Zealand. Courses are run in

reputable tertiary institutions in Auckland and Christchurch,

allowing trade and graduate students to gain the theoretical

Council lights out on new pathsknowledge and skills required to undertake high-quality lighting

design. This has been coupled with the traditional Kiwi “can do”

attitude to practical matters to produce work that is consistently

recognised to be of a high international standard.

In the last five years members of Lighting Council and their

technical staff have participated in committees concerned

with lighting and safety standards covering general lighting

requirements, emergency lighting, street and pedestrian lighting,

electrical load limitations on commercial buildings and appliance

safety and environmental issues. This has all taken place against

a backdrop of closer technical links and standardisation with

other markets, particularly Australia and also with Europe and

Asian jurisdictions. To this end Memoranda of Understanding

have been signed with LCA, the Lighting Council Australia and

the Chinese Association of Lighting Industries. Council also

has close links with the Lighting Industry Federation in the

UK and many other similar organisations in Europe. It is also

represented on the peak International Standards body, the IEC.

Lighting Council members recognise the very complex nature

of public lighting infrastructure. It suffers, as do many other

parts of the lighting industry, from a division of responsibilities

for capital and the ongoing power and maintenance costs to

different cost centres, thereby making incentivisation of more

cost effective, new technology installations a complex issue. This

is particularly so for the existing installations which have many

years to run to realise their twenty or twenty five year economic

operational period. However there are considerable opportunities

for new technology and products to be introduced on greenfield

sites and city upgrade projects. Some authorities have already

taken some steps in this direction with their upgrade plans, and

have also taken up trials of new technology in small urban areas

for the purpose of evaluating public lighting costs for the future.

These moves are entirely in keeping with overseas authorities

where the new technology has been introduced in city

beautification projects and other areas where good public

lighting can provide increased safety to residents or for the

attraction of tourism with the floodlighting of public buildings.

Some of these trials have been running long enough now to get

realistic positive data on the very important running cost factors

which represent by the largest proportion of the lifetime cost of

any lighting installation.

Members of LCNZ welcome the initiatives taken by some TAs

to adopt new products and are actively involved in providing

lighting equipment for projects including light sources as well

as luminaires. Today, specifiers and clients in this market can

gain access to all the major international technology available in

the knowledge that local support at a very high technical level is

available in New Zealand.

Lighting Council can be contacted with regard to industry

participation in energy management issues and the upcoming

legislation on lamp and hardware recycling programmes.

Council members have been involved with government

departments in the run-up to the release of RFPs on energy

initiatives, and the possible outcomes of the recent legislation on

waste minimisation.



Compressed air is often considered industry’s

“fourth utility” (behind fuel, electricity and

water), and is generally the most expensive.

It consumes up to 20 per cent of industrial

electricity usage, of which 20 to 40 per cent is

often wasted in avoidable inefficiencies.

As businesses around the country continue to look for

additional ways to cut costs in times of high power and fuel

prices, a new initiative by the Electricity Commission will help

users of compressed air identify operational and energy saving

opportunities.

The Compressed Air Systems (CAS) Auditor Accreditation

Scheme was launched by the Electricity Commission in July

2008.

The Scheme emerged from studies of compressed air systems

management in New Zealand, which identified a scarcity of

compressed air expertise independent of the compressed air

equipment industry. The commission considered that to be a

significant barrier to businesses seeking advice on compressed

air systems best practice design and operation.

Through a CAS stakeholder group that included representatives

from the compressed air equipment industry and compressed

air users, the commission developed the scheme to

independently ‘accredit’ compressed air systems auditors.

CAS stakeholder group members and the commission

determined that compressed air audit recommendations would

be more credible, and follow-up efficiency actions be more

likely to proceed, if the CAS auditors operated according to an

independent standard and were accredited by an independent

body.

Long-time practitioner in the compressed air industry and

technical advisor to the Electricity Commission Mike Allen

said: “This scheme is a welcome initiative. It’s long overdue,

to be honest. On an individual site level, a systematic CAS

audit can identify some attractive savings - many of them

free or involving low cost measures. On a national level, if

recommendations from the audits are implemented, the savings

could be significant.”

The CAS auditing guidelines and reporting standard on which

the scheme is based has been developed by the commission

and the CAS stakeholder group, and is being maintained

by the commission. The standard requires a total system

approach CAS auditing and a focus on identifying cost-effective

solutions.

To be accredited under the scheme, an auditor must have

satisfactorily completed an approved CAS Education course

and demonstrate practical capability in CAS auditing according

to the standard referred to above. Completion of the CAS

education course (provided by the University of Waikato) is a

prerequisite of applying for accreditation.

Dr James Neale, course facilitator at the University of Waikato

said: “The most positive outcome from this whole process will

be the raised awareness of the specialised skills required to

design, operate and maintain a CAS at or near best practice

standards. System auditors require a specialised understanding

of what can actually be a complex process that is too often

trivialized at the detriment of energy efficiency and life cycle

costs.”

The CAS Auditor Accreditation Scheme is administered by the

Energy Management Association of New Zealand (EMANZ).

Erin Roughton, spokesperson for EMANZ said: “This initiative

is timely. Saving energy and using energy more efficiently is a

key issue for many of today’s businesses. EMANZ is delighted

to be involved in this initiative given our broader experience

through the Energy Auditor Scheme that we established some

years ago. The most effective way to identify savings is from

an audit undertaken by a reputable auditor. The scheme is a

good fit for us as an association

– there are many synergies.

Standards are high and that’s

what industry can expect

from this scheme. We have

received several applications

for accreditation so far and

look forward to receiving even

more.”

To encourage New Zealand

industry and the CAS auditors

to be more active in pursuing

compressed air systems

efficiency, the Electricity

Commission is currently also

funding CAS audits for larger

New Zealand compressed air

users. In the near future, only

CAS auditor accreditation will

be funded by the Commission.

of the scheme including the

process to become an accredited

CAS auditor, the costs involved,

Saving energy – it’s in the air


Streetlighting is an area

with potential for gains

in both efficiency and

safety through the

progressive introduction

of newer technologies. However, it

is essential to ensure that during any

push for efficiency or environmental

sustainability in streetlighting, the

provision of appropriate levels of

lighting is not forgotten. Many existing

lighting installations fall below the

lighting levels prescribed in the current

standard (AS/NZS1158). One of the

benefits of newer lighting technologies

is they can provide more light to areas

that require it, for the same or less cost.

If streetlighting is improved, this will be

beneficial for both provider and user.

As a funder of transport activities, the

NZ Transport Agency (the NZTA) takes

an active interest in the maintenance

and upgrading of existing and new

infrastructure installations. We

recognise that there are barriers to the

implementation of new technologies,

and we want to do our part to assist asset

managers in their decision-making.

Several concerns have arisen from

observations during recent procedural

audits and technical reviews, including

supply agreement irregularities,

continued use of obsolete technologies,

increasing interest in new technologies

and their uptake, and concerns about

councils’ ability to provide appropriate

lighting to achieve safe and secure

networks while still reducing energy

consumption . Obviously both capital

and maintenance expenditure are key

considerations for councils, so any

opportunity to improve standards for the

same or less cost is of interest.

In order to assess the contribution

provided by councils’ street lighting

installations and management

towards meeting the outcomes of the

NZ Transport Strategy (NZTS), and

determine if there was any need to make

changes to standards, guidelines and

processes at national and council level, a

theme audit was programmed.

Twenty local authorities were approached

and data was gathered to assess the

management practices and standards

of their streetlighting infrastructure, in

relation to meeting the outcomes of the

NZTS.

In November 2007, the findings of the

Theme Audit of Streetlighting (2007)

were published. The theme audit

concluded that streetlighting contributes

towards four of the five objectives of

the NZTS: assisting safety and personal

security; improving access and mobility;

protecting and promoting public

health; and ensuring environmental

sustainability. Further, it was found that

there is a general need to enhance skill

levels and knowledge in street lighting

technology.

Tariff structures and fault repair

agreements were two areas where joint

action by the NZTA, Local Government

New Zealand, and the Electricity

Commission was identified as a means to

effect change.

One third of the councils surveyed were

charged for street lighting energy supply

on an annual lump sum cost basis. Such

a structure offers little incentive for

councils (or energy suppliers) to invest in

improving the energy efficiency of their

infrastructure. This aspect was outside

the scope of the theme audit, but has

been a topic of further discussion.

Many councils commented on delays

in getting repairs made to underground

streetlighting cables. The reported

average outage from cable faults was

32 days. This is unacceptably high,

with unlit streets risking the safety and

security of users and leaving councils

unable to meet community level of

service expectations. A number of

councils commented that they have

no direct relationship with network

companies and that these companies

are reluctant to enter into service

agreements. As with tariff structures,

the issues surrounding supply

infrastructure were outside the original

audit scope, but have been discussed

subsequently.

The principal types of lamp in use are

high pressure sodium (76 per cent of

total stocks) with older technologies,

mercury vapour (15 per cent) and

fluorescent (5 per cent), the other

significant types. Some councils have

significant stocks of these outmoded

lamps. In some instances programmes

to upgrade these to more modern types

of lights are unrealistically long. Fittings

at the end of their working lives become

unreliable, causing unpredictable

demands on maintenance programmes.

Lighting pathways - streetlighting and the NZ Transport Agency

By JULIAN CHISNALL



Present-day pressures are to improve

the efficiency of lamps, both as light

producers and for environmental

reasons. Changing mercury vapour and

fluorescent lamps to more efficient and

effective lamps that will provide much

better levels of service to the public is a

desirable outcome.

Street lighting inventories are not

as complete or as well verified as

the inventories for pavement assets.

This is despite the capability to store

(and manipulate) streetlight data

being available in the various asset

management systems in use, and a

general acknowledgement that councils

should hold accurate inventories for asset

valuation purposes.

The report made a number of

recommendations and suggestions to

both councils and the NZTA.

For councils:

➔ include lighting deficiencies in safety

management system (SMS) deficiency

databases or Asset Management Plan

processes;

➔ require a statement of design

compliance for new installations

similar to that specified in AS/

NZS 1158 “Road Lighting” before

handover; and

➔ ensure renewals programmes are

realistically based in relation to

stocks of outmoded lamps and the

deterioration of old fittings.

In addition, the report supported

councils:

➔ considering the adoption of a lighting

strategy document in line with the

requirements of AS/NZS 1158;

➔ considering the use of “white” lights

to floodlight pedestrian crossings;

and

➔ adopting a design life of 20-30 years

for assessing “whole of life costs” of

installations.

For the NZTA:

➔ foster the development and

establishment of introductory and

refresher level courses in street

lighting standards and technology,

for both asset management and urban

planning disciplines; and

➔ discuss the issues raised in the report

with Local Government NZ with

a view to initiating joint action to

obtaining better levels of service from

suppliers and for users.

Subsequent to the theme audit,

discussions have been held with a

number of organisations to disseminate

the findings.

Mike Jackett, an independent

consultant who conducts training

on the street lighting standards for

NZIHT, advised on the audit. Mike,

along with Graeme Culling of Betacom,

is using the recommendations and

suggestions from the audit in the

NZIHT training courses. Both are also

members of the review group for the

AS/NZS 1158 (Streetlighting standard).

The findings are being used to inform

discussion around future amendment

of the standard and the implications for

industry and local/central government.

The review findings have been

discussed with Stuart Ross (Electricity

Commission) and Geoff Swainson (Local

Government NZ). Earlier this year,

Julian Chisnall (NZTA Technical Audit

Manager) and Rob Merrifield (author of

the audit report) joined a small industry

working group coordinated by the

Electricity Commission. The group has

been working through the issues raised

by the theme audit and subsequent

discussion.

As a key issue is the likely cost of

adopting the newer technologies, NZTA

is keen to see information on whole-of-

life costing being made available to allow

asset managers to make robust long-

term decisions around the maintenance

and upgrading of their streetlighting

infrastructure.

NZTA was heartened by the impressive

turnout to the September streetlighting

seminar hosted by Waitakere City

Council, where a number of newer

technologies were showcased and two

recent installations were visited on a

night tour. This event clearly indicated

the level of interest in the issues

identified during the theme audit. There

was much discussion during the seminar

and it was great to see all parties freely

discussing their views and opinions. It

was obvious to most who attended that

a half day discussion was only a taste of

things to come.

As with all new technologies, there

may be some elements of overambitious

marketing or fragility of supply which

may taint the particular technology.

Early adopters may encounter problems

that need to be worked through in

relation to costs, design considerations,

maintenance procedures etc. The NZTA

would encourage discussion of any issues

through case studies or presentations at

fora such as the RCA Forum, Ingenium,

TRAFINZ etc to ensure that any

learnings are passed on for the benefit of

the industry.

In the long-term, the adoption of cost

effective and environmentally affordable

lighting systems will improve the

transportation network for all users and

ensure that the objectives of the NZTS

are met.

It is almost impossible for most of

us to imagine the time, long before

the invention of the light bulb, when

the stars were bright enough to cast

shadows. Nobody wants to go back

to dark alleyways, but we also know

that artificial light can pollute as well as

illuminate.

Scientists are only now studying how

perpetual twilight affects the lives of

birds and other animals, but there is

no doubt that a clear, starry night has

become a diminishing human pleasure.

Over the past hundred years the natural

patterns of the planet’s day-night light

cycles have been heavily modified,

particularly in urban areas. A full moon

at night provides illumination levels of

around one lux, with clear moonless

nights reaching less than 0.001 lux,

about a thousand times less. In sharp

contrast, New Zealand streetlights can

provide upwards of 25 lux.

Lighting practices have traditionally

reduced initial capital investment by

installing fewer, brighter luminaires

which spill light as widely as possible

across the area to be lit, and beyond.

Subsequent ongoing energy costs have

not been of concern. This has led to

wasteful conditions such as glare and

light spill outside of the area to be lit,

including upwards into the sky.

Light spill is wasted energy. Two

Japanese astronomers in the late 1990s

estimated waste energy from light spill

from many cities around the world

by assessing satellite images. They

estimated Auckland’s waste energy

at 5.73 GWh per year. These satellite

images were used to create the well

known world at night photo, showing

the world’s urban areas spilling light into

space.

A Street Lighting Energy Efficiency

Study in 2001 from the Energy Efficiency

Conservation Authority (EECA) reports

that 159 GWh is used by all territorial

authorities to supply their streetlights.

Work by the ICLEI-Local Governments

for Sustainability-Australia/New Zealand

in the South Australian Strategic Action

Planning Guide for Sustainable Public

Lighting estimates that 60 to 65 per cent

savings can be made through the use of

new technology lamps and luminaires

that direct light to the required area.

This would mean annual savings of

around 98 GWh if all New Zealand

streetlights were upgraded.

But the benefits are greater yet. This

98GWh represents approximately

200GWh of fossil fuels that could

remain in the ground each year as

Ministry for Economic Development

figures show that there are losses of at

least 50 per cent from energy source

to end user through the New Zealand’s

national grid system. The greenhouse

gas savings from this is equivalent

to removing 26,000 light passenger

vehicles from New Zealand roads.

Astronomers initially filled the role of

“canaries of the night” warning the all

was not well in the night environment.

Supporters of the call for energy efficient

and environmentally friendly lighting

include:

International Energy Agency,

Lighting Council NZ with their NZ

Efficient Lighting Strategy

New techniques and shielding

technologies can direct the more precise

amounts of light to the area to be lit,

while preventing unattractive glare

and light spill. By using these new

technologies, territorial authorities can

not only achieve the standard of lighting

required, but also use fewer poles and

fittings and significantly reduce energy

consumption and maintenance costs..

The RASNZ, as inaugural signatories to

the New Zealand Urban Design Protocol,

has been raising awareness of the value

of the night environment. This includes

supporting the Illuminating Engineering

Society of New Zealand Lighting

Awards.

Over the past four years, the RASNZ has

taken great pleasure in presenting three

awards for lighting excellence.

In 2006 the Ports of Auckland

won the award when they replaced

1300 floodlights with 650 new

environmentally friendly floodlights.

These new highly efficient OptiVision

lights by Philips Lighting resulted in 10

times less light spill and substantially

less glare. The resulting electricity

savings could power 400 average

households for a year.

The 2007 award was won for the

Building 3 Post Office Precinct in

Queenstown designed by Robert Warner

and Stephen Page of Cosgrove Major

Consulting Engineers, Christchurch.

An excellent attempt has been made to

tightly control the lighting; not only to

enhance the beauty of the building but

also to minimise light pollution and

glare.

The 2008 award was won by Paul

Wilson of the Queenstown Lakes

District Council and Andrew Wray

of Modus Lighting for the Wanaka

waterfront playground project.

“The lantern matches our earlier style

of pendant lantern but has significantly

improved energy efficiency, glare

control and protects the night sky from

unwanted light spill,” Mr Wilson said.

It is particularly pleasing to see two

recent awards in the Queenstown Lakes

District following the development of

the Southern Light Strategy by QLDC.

The council’s work on the Southern

Light Strategy is well noted around

the country and its determination to

implement the strategy is appreciated.

In the North Island, Waitakere City

Council’s recent Advancing New

Zealand’s Street Lighting Technologies

forum is an excellent example of the

leading thinking required to initiate

change throughout New Zealand.

Further events are proposed to cover

other aspects of outdoor lighting.

The RASNZ is pleased to see the

technological changes that are occurring

within the lighting industry, and is

keen to see greater awareness amongst

territorial authorities of the need to

effectively manage the impacts of

lighting on the night environment.

All of us can be winners, financially,

aesthetically and environmentally if new

lighting technologies are applied with

care and concern.

Harper Avenue is a significant arterial corridor in Christchurch, linking northwestern suburbs to the central city and bisecting picturesque Hagley Park. Balancing high traffic volumes with a high profile made this a challenging project.

CASE STUDY: Harper Avenue street lighting upgrade

PROJECT SCOPE

Connetics was appointed by the Christchurch

City Council to undertake a full lighting upgrade

on Harper Avenue. This included replacing

older-style lights and poles with a system that

meets current standards and performance

requirements.

The project was complicated by high traffic

volumes, pedestrian usage and crossings, the

presence of large trees on both sides, a narrow

median, bridges, and complex intersections.

OUR RESPONSE

Connetics’ role began with a comprehensive

project assessment. Early in the design process

we made a recommendation to retain the

lighting system in the existing median strip to

reduce the disruption of relocating trees and

other infrastructure.

The Connetics team also managed the liaison

with residents and stakeholders, made regular

checks with the City Council, and gained

necessary approvals from electricity network

operator Orion. Connetics was also responsible

for the initial 12-month maintenance period.

TECHNICAL CHALLENGES

Retaining the median location required existing

cabling to be reused in existing locations. Some

poles were also reused, while the location

of new poles had to be carefully planned in

relation to trees, bridges and other structures.

Managing the logistics was also a challenge. As a category V2 road, Harper Avenue carries some of the city’s highest traffic volumes.

SOLUTIONS

Connetics carried out straight-road and curve-road lighting calculations to ensure maximum spacing between lights while achieving full compliance. Computer modelling was backed up with on-site assessment and measurement.

The use of high-efficiency lighting technology achieved a dramatic reduction in energy use over several circuits. Most luminaires were reduced from 250 watts to 150 watts. With integrated control gear, these also provide significantly longer life and lower maintenance costs. On-site work was carried out in sections, with extra resources assigned to safety, lane control and traffic management.

RESULTS

The new lighting provides high standards of visibility for road users and enhanced the visual appeal of Harper Avenue as a prominent gateway to the central city. Trees, bridges and other features are well protected and illuminated, pedestrian lighting enhances public safety and parkside vistas have been retained.

Overall lighting levels are excellent with good uniformity, no obvious shadow areas and very little ‘zebra’ effect (alternating light/dark). The upgrade is also fully compliant with the City Council’s draft infrastructure design standard. Increased energy efficiency and high performance specifications have contributed to lower operational and maintenance costs.

“Connetics’ project management on this upgrade was excellent. They developed an appropriate and effective design, and carried out the installation to a high standard. This was a difficult site to design for and to work on, but Connetics’ expertise ensured our requirements were fully met. They resolved unforeseen problems quickly and kept us well informed at all stages throughout the project.”

challenges. How we generate and use energy

is a crucial part of the way we adapt to this

challenge. Energy efficiency and renewable

energy offer cost effective solutions to our climate

change problems. And they come with additional benefits – we

lessen our impact on the environment, improve the health of

our communities, develop more competitive businesses and

demonstrate leadership, both here and overseas.

Leadership needs to come from all quarters, including central

and local government, if we are going to meet our emission

reductions goals, and it is a role that is being taken seriously by

both parties.

New Zealand now has energy strategies that clearly define where

we want to be and how we are going to get there. The New

Zealand Energy Efficiency and Conservation Strategy (NZEECS),

launched in October 2007, is the action plan to make the most of

our energy efficiency and renewable energy opportunities.

The strategy recognises that if we want to motivate and

encourage change, the public sector need to lead by example by

reducing their own energy use, and facilitating change in their

communities.

One of the ways that local authorities can reduce their own

energy consumption is through the use of efficient street

lighting. It is estimated that street lighting costs local authorities

throughout New Zealand $18m per annum and generates over

25,000 tonnes of CO2 emissions.

Earlier this year, the Electricity Commission formed the street

lighting industry working group to look into ways of reducing

the amount of electricity we use in this area. Government

representatives and members of the lighting industry are

working to understand all of the opportunities and what role

new technologies might play. What they come up with will

determine the next steps local government can take to start to

realise the potential savings.

Progress has already been made in some areas. In June 2007, the

Sea Breeze residential subdivision in Whangamata, Coromandel

was the first region in the southern hemisphere to install the

‘CosmoPolis’ white light system. These lights, manufactured by

Phillips Lighting, use 10 per cent less energy than orange-glow

high-pressure sodium lamps, whilst providing greater safety

through better visibility. Since then Waitakere City Council

has also installed more than 200 of these lights in part of their

catchment area.

In September 2008, Waitakere City Council hosted a day-

long seminar “Advancing New Zealand’s Street Lighting

Technologies” in recognition of the growing interest in this area.

The support from Waitakere City Council for their peers is

outstanding – it demonstrates that through working together

and sharing our experiences on similar challenges we can realise

the benefits of successful energy management sooner.

Lighting technology is advancing quickly. Recently Auckland

International Airport was awarded a grant to enable them to test

and independently monitor LED lights in some of the airport’s

car parks. It is expected that this project will reduce their CO2

Lighting a path aheademissions by 60,000 tonnes over the next 10 years.

The Energy Efficiency and Conservation Authority (EECA)

supports local government to achieve their energy efficiency

targets. For the first time this financial year, local authorities

are able to apply for grant funding for demonstration projects of

new and underutilised energy efficiency technologies.

Street lighting projects that use a new technology that could

be replicated by other councils could qualify under this grant

programme.

EECA also offers low-cost loans to local authorities and other

Crown organisations to help energy efficiency projects get off

the ground.

Conservation Authority (www.eecabusiness.govt.nz 04 470 2220).

...street lighting costs local authorities throughout New Zealand $18m per annum...


The 340,000 streetlights in New Zealand use 148

million kWh of electricity, release around of

30,000 tonnes of carbon dioxide, and cost local

government and the New Zealand Transport

Agency (NZTA) more than $20m in energy and

network charges per year.

The potential for energy efficiency and greenhouse gas

(GHG) savings from new streetlighting technologies and

operating regimes is substantial. This article reviews

the development and operation of the ICLEI Oceania

coordinated Sustainable Public Lighting (SPL) programme

in Australia, and recommends the implementation of a

similar programme for New Zealand.

ICLEI - Local Governments for Sustainability is an

international association of local authorities that have made

a commitment to sustainable development. Worldwide,

ICLEI has nearly 1000 local government members, and

The sustainability of streetlights in New Zealand

By IAN SHEARERmany more councils participate in a large number of

sustainability programmes. ICLEI Oceania operates in

our region through separate not-for-profit companies

in Australia and New Zealand. ICLEI Oceania supports

councils with the Communities for Climate Protection

– New Zealand programme with funding from the

Ministry for the Environment. That programme is part

of ICLEI’s international Cities for Climate Protection

Campaign.

Reviews of barriers to the implementation of new,

more energy efficient streetlighting technologies and

operating techniques have been produced for the Energy

Efficiency and Conservation Authority (EECA) and the

Electricity Commission. The “New Zealand Efficient

Lighting Strategy”, developed by a joint industry-

government working group, includes some street

lighting elements, but involved little local government

input.

Standards organisations in Australia and New Zealand

are considering changes to the current A/NZ 1158

streetlight standard. Minimum energy performance

aspects are being considered. However, it is the new

European Union energy efficiency standards that are

likely to drive the future regulatory environment for

streetlights in New Zealand.

Streetlighting contributes to many outcome areas of the

New Zealand Transport Strategy including:

Assisting safety and personal security

Improving access and mobility

Protecting and promoting public health, and

Ensuring environmental sustainability.

However, an NZTA review noted that streetlight

electricity tariff structures were confusing, inconsistent,

and a disincentive to energy efficiency; that there

were difficulties in working with network companies;

that some councils have significant stocks of obsolete

luminaires; and that streetlighting inventories are

not as complete or as well-verified as inventories for

pavements.

At present, almost all streetlights in New Zealand are

fed from un-metered supplies and the electricity usage

is charged on an estimated load basis. Thirty per cent

of councils are charged for streetlighting energy and

network services on an annual lump sum cost basis.

The inability to measure actual loads and establish load

profiles and then measure and validate savings from the

introduction of new technologies or control approaches

is a major barrier to implementation of improvements.

Regulatory barriers to the acceptance of advanced

streetlight dimming control systems and software-based

energy metering systems, which are available in Europe,

have not yet been solved. Page 22

In today’s financial climate, capital for

infrastructure investment projects is

likely to be more difficult to source

and, in tighter economic conditions,

budget constraints add further

difficulties. On the other hand, private

investors are seeking opportunities that

provide low risk and good security for

their funds.

From an environmental perspective,

the world’s economic woes may mean

reduced appetites to fund energy

efficiency projects that reduce carbon

emissions. This is because such projects

tend to be diverse and have difficulty

defining and delivering measurable

returns.

One type of investment opportunity

that has the potential to resolve all the

above issues and provide improved

infrastructure for communities is

streetlighting. It is possible to combine

both public and private investment

capital to upgrade our aging street

lighting infrastructure and provide good

returns through the savings realised by

reduced energy and maintenance costs.

The barriers to investment in efficient

streetlighting can be categorised as

arising from technological, policy or

financial issues. In the technological

category, the lighting industry is rapidly

developing new lighting hardware

and lighting controls that are largely

addressing many of the technological

barriers. Solutions are being proposed

that will overcome the metering and fixed

charge barriers. TLAs now need to think

creatively and develop policy frameworks

that will encourage innovation and

investment in infrastructure. Introducing

frameworks that will enable private

investment in TLA owned infrastructure

projects will present real opportunities

for communities to benefit from

improved services with a lower impact

on rates.

The proposition is that, for efficient

streetlighting, a new type of funding

mechanism can be developed. This

mechanism will enable both public

and private funding to be used with

returns generated from energy and cost

efficiencies. This type of capital funding

removes the requirement for efficiency

projects to compete with others for a

share of the TLA capital budget and

produces a secure, long-term investment

for superannuation and other low risk

schemes.

The proposed funding mechanism would

be:

1. focused only on streetlighting;

2. designed to attract new funding into

the market;

3. appeal to long term low risk and ‘green’

investors; and

4. produce secure returns as a result of

long-term contracts with TLAs and the

ongoing requirement for street lighting

Establishing such a funding mechanism

for streetlighting would allow TLAs to

carry out the streetlighting investments

in a systematic way using the most

efficient technology on the market whilst

at the same time, achieving modern

lighting standards for the community.

Repayments to investors are made

through the energy and other cost savings

that are made over an initial contract

period. Essentially, the TLA agrees to

pay the running costs that it would have

incurred had the investment not been

made and the difference between this

and the actual (reduced) costs repay the

capital and provide interest to investors.

After the capital has been repaid via the

savings, the TLA will receive the full

ongoing benefits of the reduced costs.

A combination of TLA and private

investors provide a sustainable fund

which is then used to finance efficient

streetlighting projects that meet the

fund’s criteria. Through aggregation of

several projects, economies of scale and

improved purchasing can be obtained.

Cashflows from energy efficiency and

other cost savings are used to provide

returns to investors and, if appropriate,

provide bonuses to participants (e.g.

designers and suppliers). Other sources of

funding that assist these types of projects

may be available from government

agencies such as EECA and the Electricity

Commission.

The structure of the fund may also allow

for a positive balance to be generated and

retained, allowing the fund to grow and

finance an increasing number of projects.

The Sustainable Capital Company is

currently developing a proposal for

TLAs to investigate the options and

structures that could form the basis for

the sustainable fund. At this stage, it is

intended that an initial group of TLAs

that are committed to working together

to find a financial solution to efficient

lighting investment will be identified.

The TLA group would work with the

Sustainable Capital Company and

interested lighting industry participants

to develop a framework for the fund. Pilot

projects would then be identified and an

investment prospectus developed.

Following the establishment and

operation of a number of pilot projects, it

would be possible to undertake a national

rollout of the sustainable fund.

Public and private funding of

infrastructure projects provides solutions

to the current financial issues facing

TLAs and investors. Streetlighting

technology provides significant

opportunities to create wealth and

have a positive environmental impact.

Policy changes and new approaches

may be required to overcome barriers

to innovative new means of financing

projects. The creation of sustainable

fund type mechanisms for financing

infrastructure projects may provide

an important pathway for TLAs. New

efficient street lighting technology looks

to be an ideal candidate for developing

and road testing the sustainable funds

concept.

Energy Limited; director, the Sustainable

Capital Company.

initial group can contact Mark Copsey of

A sustainable fund for efficient streetlighting

By BILL HEAPS


Public Lighting in AustraliaIn Australia, public lighting energy use

has grown 45 per cent over the past 14

years and it produces approximately

1.15 megatonne of CO2 per year

(Poulton et. al, 2005). On average, it

is the second largest source of local

government corporate GHG emissions,

accounting for about one third of

councils’ corporate greenhouse gas

emissions (but up to 70 per cent in

some cases) and one third of their

electricity bill. Streetlight electricity

costs Australian local government more

than $A100 million per annum.

Australian CCP councils’ average annual corporate GHG emissions Research by the Australian Government

indicated that reductions of up to

65 per cent in energy consumption

were possible without compromising

public safety or aesthetics (Poulton

et. al, 2005). Despite this significant

abatement potential, and many

individual projects undertaken

by councils, the uptake of new

technologies and practices has

been limited. Only one council has

successfully retrofitted its entire public

lighting stock (Coffs Harbour City

Council, NSW in 2005).

A review recommended the

establishment of a Sustainable Public

Lighting (SPL) programme to deal with

the barriers. The three main barriers

were market and regulatory barriers;

limited local government capacity; and

poor coordination of existing efforts.

Streetlight services in Australia are

generally funded by councils but

electricity distribution businesses own

and control the assets. Distribution

company barriers included

unfamiliarity with new SPL products,

entrenched attitudes and behaviour,

and upheavals in management and

ownership regimes.

Local authorities often lacked the

information, skills and resources to

participate effectively in dialogues and

contract negotiations with distribution

businesses about public lighting.

The market/regulatory and local

government capacity barriers were

also exacerbated by a diffusion of

information on appropriate resources.

Technical research and information

dissemination was uncoordinated and

poorly funded, and it was difficult for

councils to access the up-to-date and

detailed data required for decision-

making.

The Australian Sustainable Public Lighting ToolboxSince 2003, ICLEI Oceania had been

helping Australian councils complete

street lighting projects as part of

the Cities for Climate Protection

programme. This experience was

captured and developed further when

the Australian Federal Government

contracted ICLEI Oceania to develop

the Australian Sustainable Public

Lighting Toolbox, and make those

resources freely available to all

councils on the web (http://www.iclei.

org/?id=2474).

The main resources available through

the Australian SPL toolbox include:

Public lighting calculator, showing

energy and greenhouse savings from

changing a council’s existing lighting

stock with different efficiency options

Guides, tools and templates for creating

action plans.

A developers’ guideline and checklist,

and a developers’ guide to solar public

lighting.

Model streetlighting community survey

forms.

Innovative streetlighting policies, as

examples.

Reports and case studies, and

A free technical Q&A service for public

lighting queries.

Important lessons for New ZealandThe potential for significant savings

of energy, GHG emissions and dollars

from improvements to streetlighting

system should be a strong focus for New

Zealand councils. Experience from the

work of leading Australian councils

in the sustainable public lighting

programme confirms that these savings

are easier and more cost effective to

achieve through collective action. The

development of a sustainable public

lighting programme for councils in

New Zealand should incorporate the

following key elements. It should:

Be structured to establish inventories,

goals and action plans.

Provide advice on council management

structures that clarify and consolidate

asset and data management, technical

understanding and capacity.

Incorporate sustainable public lighting

strategies, policies and guidelines.

Provide guidelines for engaging

the community and developers in

the planning and design of new

installations for council-owned

lighting.

Build the business case to garner senior

management and council support for

broader changeovers.

Establish national or regional

action groups of councils and other

stakeholders to share technical options

and strategic barriers.

Facilitate the working together to

implement trials, undertake tariff

negotiations, advocacy, research and/or

financial modelling.

Facilitate the development of large-

scale project models for financing and

bulk procurement, the establishment of

revolving energy funds, and investigate

energy performance contracting

opportunities.

Australian and New Zealand

streetlighting standards are the same

and the actual technologies used and

the design requirements are similar, but

the asset management processes used

and the ownership of public lighting

are different.

Much of the information and tools

in the Australian SPL Toolbox could

be converted and modified for use in

New Zealand. ICLEI Oceania would

welcome the opportunity to work with

local and central government and the

street lighting industry to make this

happen for New Zealand.

lighting resource kit and a

universal streetlighting infrastructure

design standard (IDS) which are to be

rolled out to all councils in 2009 by way

of a structured promotion, education and

training programme. This programme

will target the information barrier as a

priority, as well as barriers relating to

split incentives, procurement/regulatory

policies and the focus on up-front capital

cost.

The resource kit is intended to provide

councils with resources on available

street lighting technologies, as well

as tools to compare new technologies

and assess the benefits, develop street

lighting policies that incorporate relevant

electricity efficiency considerations,

and present robust business cases for

network upgrades. The IDS, which will

set universal, standard specifications

for new installations, will help ensure

new installations deliver high quality

light output while minimising electricity

consumption.

While this will support councils to

achieve their energy efficiency targets,

other barriers, such as mercury vapour

lamps, tariff structures, and un-metered

street lighting may limit the savings

that can be achieved. More work is

required to determine the extent of

mercury vapour lamps within street

lighting networks and in council

stockpiles, better understand tariff

structure constraints across councils,

and investigate metering and billing

opportunities to allow councils to receive

the electricity savings and financial

benefits that modern street lighting

control systems can provide. The

outcome of this further work will inform

potential future programmes.

Attendance and industry participation at

the Waitakere City Council’s September

street lighting forum “Advancing New

Zealand’s Streetlighting technologies”

highlighted the growing interest in

efficient streetlighting. This, combined

with the LED and metal halide trials

currently underway in some districts

highlights the momentum that is

beginning to gather, and the growing

opportunities to work together and share

knowledge and experiences on a national

basis.

The commission’s proposed street

lighting programme will build upon

this momentum by addressing some

key barriers to the uptake of efficient

technologies and providing practical

support for councils to achieve their

energy efficiency targets.

Page 11

Page 6 is an excellent outcome by any

measure.

To go further however and achieve the

goal of carbon-neutral lighting, zero

carbon electricity is required. There

are a number of ways to achieve this, to

generate on site at the proposed street

lighting location small scale renewable

energy technologies can be used.

Most street lighting installations will

have ready access to a grid connection.

Utilising grid connect inverters generated

energy can be fed directly into the grid

avoiding the need for storage, e.g. batteries

(and associated cost and maintenance).

Grid supply can meet the peak energy

demand requirements meaning that

the renewable energy system can be

optimised to generate the average energy

consumption of the lighting installation.

Energy generated when renewables

resources are available (e.g. sunlight

during the day) can fed to the grid

gaining CO2 credits. These credits offset

the use of “dirty” electricity that is used

for lighting at times when energy from

renewable sources is not available.

As the majority of street lighting is

in urban areas photovoltaics (PV)

are generally most suited small scale

renewable generation technology. Small

wind turbines are the other option but

often have low energy yields in built up

areas due to low average wind speeds and

high turbulence. They also have greater

maintenance requirements.

For a hypothetical installation with

3.6 km of road, 170 square metres of

crystalline PV would generate the 24

MWh of electricity required by the energy

efficient lighting installation on an annual

basis (based on Auckland irradiance

levels). Approximately 50 square metres

of PV per kilometre of road. This is a

very small area given the huge amount of

roof space on buildings in New Zealand.

Where possible the roof space of public

buildings and structures could be used.

Alternatively roof leases are a common

mechanism used international to secure

un-utilised private roof space for energy

generation.

At present solar PV technologies are an

expensive means of generating electricity,

with poor paybacks. Combined with

energy efficiency measures this approach

to carbon neutral lighting does however

have paybacks well within the life of

the system and a positive return on

investment.
