any years ago, in an entirely different journalistic incarnation, I spent a week trying to live as greenly as possible and then

reporting my attempts, failures and successes in diary form. How hard can this be? I thought. Actually it was very hard because the computations were so complex and because it was difficult to know how far back to track in the comparison, say, between having clothes made of wool, cotton or artificial fibre – never mind the manufacturing processes or different ironing temperatures, where did the sheep come from?

When it comes to carrying out an accurate and rigorous analysis of fluorescent sources vs LEDs, the exercise is even more like pinning jelly to a blackboard because the latter technology is moving so fast that constant recalibrations are needed. Thomas Paterson of Lux Populi was commissioned to carry out just such an analysis for an airport (Maintaining a sense of proportion, p16) and has produced one of the most detailed studies yet of whether LEDs are actually at the stage where

they make sense on all levels, rather than just on the basis of fairly superficial comparisons. Talking of ‘are we nearly there yet?’, solar-powered street lighting is probably up there with OLEDs in holding out much promise but remaining in an applications niche. Francis Pearce investigates if we are any nearer the sun as a viable source (Sunrise industry?, p10).

Bluesky trials light-use night mapping system Aerial survey specialist Bluesky is to conduct trials of the world’s first integrated night mapping system.

The aim of the trials is to produce essential data to help combat light pollution, energy wastage and help manage urban habitats.

The Night Mapper system combines a specially adapted camera with Bluesky’s LiDAR (light imaging detection and ranging) and thermal-imaging sensors. The resulting map-accurate images will be a useful tool for managing street lighting operations and maintenance, and as a resource to tackle energy inefficiency, according to Bluesky.

It has developed the system in partnership with the University of Leicester following a Blueskyfunded research project.

‘By integrating a camera,

specially adapted to cope with the challenges of nighttime surveying, within our state-of-the-art aerial mapping system we can ensure high levels of positional accuracy for the night-time images,’ said James Eddy, Bluesky’s technical director and industrial associate at the University of Leicester. ‘Co-capturing detailed 3D measurements and thermal images will provide additional intelligence relating night-time light levels to heat loss and height.’

The images produced by the system can be used in a desktop mapping tool or geographical information system (GIS). Using advanced spatial queries and mapping techniques, the data can be used by local authorities to provide

Yotta lands largest ever Horizons contract The Highways Agency has awarded a £600,000 contract to Atkins and Yotta for the supply of Yotta’s Horizons visualised asset management software and associated implementation services.

The contract marks the largest implementation of Horizons to date worldwide.

Atkins is providing project management and quality assurance services.

The software will allow the HA to model the current and future condition of the

Lighting Journal March 2014

network based on its national pavement condition survey data. This model will then be used to predict where and when maintenance is likely to be needed.

Horizons will incorporate data gathered from a package of condition surveys delivered

by Yotta for the HA, including traffic speed condition survey (TRACS), skid resistance and Deflectograph surveys, as well as providing visualised asset coverage of England’s trunk roads and motorways, covering

around 30,000 lane kilometres.

‘It is vital that highway authorities can make the most of their existing assets, to provide efficient and effective services to road users,’ said Alan Taggart, Atkins’ asset management service director.

‘This partnership demonstrates how collaboration between technology providers and asset management consultants can ensure the Highways Agency can deliver on their business objectives by using effective asset management solutions.’

Bournemouth goes for LEDs Bournemouth Borough Council is to replace all of its street lighting lamps with just over 16,500 LED luminaires.

The project, which will also include replacing 1000 lighting columns, is backed by £4.26m Salix funding. A further £3.5m from the council’s prudential fund will be needed to move forward with the project. Mouchel was responsible for developing the outline business case and Designs for Lighting has acted as consultant.

Currently Bournemouth spends £1.1m a year on street lighting energy. Following the upgrade, the council estimates 73 per cent savings in current street lighting consumption and reductions of £32.2m against current projected costs over 20 years. The scheme will also save 3700 tonnes of carbon a year, the equivalent of 19 per cent of current council emissions.

‘Once the work has been completed, in each full operating year the council will be £750,000 better off,’ said councillor Michael Filer, cabinet member for transport. l In an entirely separate exercise, Bournemouth Borough Council is also conducting a feasibility study into the possibility of installing Wi-Fi in its street lights, especially in the seafront area of the town.

Durham wins sustainability award

Durham County Council has picked up a sustainability award for the city’s £600,000 World Heritage Site castle and cathedral lighting scheme. The new energy efficient scheme by Stainton Lighting Design Services came third behind two overseas projects at the international Auroralia Awards for the best initiatives in sustainable lighting. The awards are organised by Schréder and LUCI (Lighting Urban Community International).

‘To get third prize out of 26 projects shortlisted around the globe is an outstanding achievement,’ said John Reed, DCC’s head of technical services.

The LED floodlights, warm and neutral white to distinguish between the two buildings, are on DMX control systems to allow dimming and flexible operation for changing circumstances and special events.

The scheme, implemented by AK Lighting and Signs, was highly commended in the outdoor lighting category at the Lux Lighting Awards and has been shortlisted for Heritage Award in the Lighting Design Awards 2014.

Winner of the award was Nîmes in southern France. As part of its Urban Transport Scheme, the city is actively limiting traffic in the centre and key to this is a new bus service running from the city centre to the A54 motorway.

Lighting designer Côté Lumière created an energy efficient scheme for the route which took into account the different landscapes.

Second prize went to the Parque Bulevar Céntrica, a 240,000sqm mixed-use cultural, sports and educational scheme in Ibarra, Ecuador, lit using LEDs with a hydroelectric power supply.

GIB launches Green Loan scheme The Green Investment Bank (GIB) has launched a new Green Loan designed to help local authorities make the switch to LED street lights.

The new scheme offers local authorities a low, fixed-rate loan over a period of up to 20 years.

Specifically designed to finance public sector energy efficiency projects, it ensures that repayments are made from within savings, says GIB. Glasgow City Council is aiming to be the first recipient to help it upgrade its 70,000 street lights. ‘Glasgow is leading the way in meeting existing challenges head on to become a smarter, more intelligent city,’ said councillor Gordon Matheson, leader of Glasgow City Council (pictured right with GIB chairman Lord Smith

of Kelvin and Secretary of State for Scotland Alistair Carmichael).

‘One of our current measures is set to see us become the first local authority to receive a Green Investment Bank loan as we work towards further embracing low energy street lighting.’

The scheme can also include a development loan to help local authorities with the costs of progressing their plans. The estimated payback period is as early as five years.

‘The GIB Green Loan is essentially a corporate loan facility that covers the set-up, capital investment and installation costs of lighting upgrades to LED, with repayments being made from within forecast savings,’ said GIB chief executive, Shaun Kingsbury. ‘Put more simply, local

authorities borrow money from the Green Investment Bank, but repay the loan entirely through the money they save by changing their lighting.’

The GIB, launched in November 2012 and headquartered in Edinburgh, has £3.8bn of funding from the UK government.

PET project As Brazilian Alfredo Moser demonstrated when he started a worldwide eco trend by creating natural-light lamps out of roof-recessed water-filled bottles, it’s amazing what you can do with an empty plastic receptacle. Following an international study led by Nottingham Trent University, we now have lights, and potentially street lights, made from recycled fizzy drink bottles.

In collaboration with Spanish SME Ona Product SL, rbeing available inesearchers have developed a new

LED-based lighting system which is housed in a recycled polyethylene terephthalate (PET) casing, a material commonly used to contain soft drinks.

The product will be made by Ona Product SL initially for domestic and commercial purposes, but there are ambitions for it to be used for street lighting as well.

The PET casing, which has a lower environmental impact than aluminium, accounts for 80 per cent of the materials used in the product. The material was also found to withstand the heat emitted by the 3W LEDs comfortably and conducted light well.

All the wiring is made from recyclable copper and PET, and heatsinks are made from recycled aluminium.

‘We were determined to raise the bar and create a new range of lighting with a very low environmental impact and found that PET, because it is so widely recycled and because of its optical, thermal and UV properties, was the ideal material in which to house LEDs,’ said research leader Professor Daizhong Su, head of the Advanced Design and Manufacturing Engineering Centre (ADMEC) of the university’s School of Architecture, Design and the Built Environment.

The product will be sold initially in Sweden from the summer, followed by other Scandinavian countries with short daylight hours in the near future, before being available in the rest of Europe. www.ona.es

News in brief A ban on GLS lamps will come into force on 1 July in the UAE. The measure appears not to affect halogen sources which, along with CFLs and LEDs, are being recommended as substitutes by the authorities. The move, estimated to save Dh668m (£109m) a year on energy bills and carbon emissions, is part of an indoor lighting standard that comes into effect on that date. An estimated 85m lamps are in use in the UAE, of which 78 per cent – around 63m — are GLS.

LIGHT Minded...

Mismatch between planning conditions and best practice lighting is resulting in approved schemes with real negative impact. Alistair Scott, managing director of Designs for Lighting, continues the debate on light nuisance and obtrusive light There are a number of issues related to the implementation of light nuisance legislation, particularly when assessing complaints on installations with valid planning approval.

There is often a mismatch between the planning conditions and best practice lighting design. The planning conditions do not necessarily minimise the negative impact of the lighting on residents, often due to a lack of understanding of lighting design and the impacts of obtrusive light. This is resulting in approved schemes that provide a real negative impact on local residents.

Light nuisance and obtrusive light are entirely different, yet we only have the ILP Guidance Notes to assist us. Often the environmental health officers have neither the lighting expertise nor tools to definitively rule on any particular installations.

Artificial lighting can be a statutory nuisance under the 2005 Clean Neighbourhood and Environment Act. The description of light nuisance is ‘artificial light emitted from premises so as to be prejudicial to health or a nuisance’.

However, this does not include artificial light emitted from a long list of premises mainly associated with transport purposes such as airports, harbours and railway premises.

There are also no specific quantitative criteria that determine whether a lighting installation is causing a nuisance.

Where a light nuisance is caused by lighting from a business or relevant outdoor sports facility they are afforded the defence of ‘best practical means’, which then requires the authority to show that the design could have been improved.

So what are the issues with the legislation? The legislation does not seem to be fully considered at the design stage and is often only used when the installation is fully operational, thus making it expensive to remedy. It is very vague in its wording and leads to ambiguity in its interpretation.

Artificial light will rarely be considered as prejudicial to health in the legal sense, although I have met plenty of members of the public whose lives have been adversely affected by the impact of such lighting.

Often artificial lighting is only one aspect and it will be accompanied by the physical presence of high masts visible by day and night. In addition there will be the

Lighting Journal March 2014

intrusion of noise including foul language from the users. Some residents state that they could live with the light intrusion, if it were not for the noise.

Light is defined as being a nuisance when it impacts on the enjoyment of an individual’s amenity within their property.

But how do we quantify this loss of amenity?

Obtrusive light entering the house is one area where residents get very upset and it doesn’t take much light to create a feeling of brightness within an otherwise dark environment such as a bedroom with the lights off. Measurements as low as 0.2 lux on the bedroom wall, caused by intrusive light, are considered a nuisance by the resident. This is less than moonlight and far less than the ILP guidance levels.

The major problem associated with sports floodlighting is that it is a bright source in a generally low ambient luminance environment, and we may be looking at a very large visual scene that includes the floodlights, the masts and the illuminated surface (if viewed from above the level of the pitch). Double asymmetric floodlights should be used in preference to symmetrical floodlights with cowls.

The source intensity from the floodlight should be within limits set by the ILP Guidance Notes; however, this cannot practically be measured, but can be calculated using photometric data from the luminaire manufacturer and a suitable calculation programme. This assumes that the floodlight is installed in accordance with the design calculation and that all louvres and cowls are included in the photometric i-table. A number of specialist sports floodlight manufacturers seem strangely reluctant to part with this information. Do they have something to hide?

One solution could be to create guidance planning conditions that local planning authorities should adopt. These would insist that full information on obtrusive light be provided with the planning application, including light source intensity and vertical illuminance for all potential sensitive receptors. This information should be assessed by a lighting professional employed by the authority and in this way many of the issues of obtrusive light may be mitigated before becoming a light nuisance.

Opinion

LIGHT Hearted Paul Nulty of Paul Nulty Lighting Design on creating emotional connections Part creative, part engineer, part QS, part project manager, part psychologist, part scientist, part sociologist, part salesman, a dollop of architecture, a dash of interior design and a sprinkling of product design and a dusting of future technology. The role of lighting designer is multi-faceted and demanding.

Mix in long hours and cold, wet nights stood on building sites and those ever so enjoyable meetings with difficult contractors, and you can do nothing but admire the educated professionals the lighting design industry produces.

So what is it about working with the medium of light that draws such talented people in? If you talk to any lighting designer you’ll find them excited and passionate, effectively living and breathing light.

Light is the agency that facilitates the relationship people have with their environment, how it’s perceived and how we connect to it. The very best lighting designers, be they architectural, theatrical or film, can tap into and connect with people’s emotions. Part of the reward of working with light every day is creating that emotional connection.

I know I’m not alone; almost every lighting designer I talk to has the same love, awe and dedication for the medium we work with. When I meet students wanting to break into the industry it’s fairly easy to see who will and won’t do well as it’s passion for light that shines through.

So what is it that draws people to lighting design? I think it’s diversity: the variance of the role, the required skillset, the industry background, the types of projects and the range of clients. Without doubt, no two days are ever the same.

We work in a truly wonderful industry and I feel privileged to be part.

The challenge for all of us is simple – how do we spread that message?

Sunrise industry?

Performance is going up and price is coming down, but how close are we to viable solar-powered street lighting? Francis Pearce investigates

P

hotovoltaics have found a role in amenity lighting in the UK where PV is used to light paths and parkland, but despite recent improvements in efficiency and cost, purely solar-powered street lighting is still struggling to take off in the UK. ‘I seriously doubt that the streets of London will be illuminated by solar power street lighting; the technology is simply not advanced enough,’ says Dave Franks, Westminster Council’s service development manager (public lighting). He cites capital costs, battery life and ‘warranties with unknown companies’ as factors militating against solar’s rise.

David Lindenberg of SolarTech, though, offers a ray of hope for solar.

‘Some local councils may still be sceptical of introducing solar street lighting, based on the assumption that it may not be cost-effective, or provide reliable lighting throughout the night.

There are also concerns that the lights

Lighting Journal March 2014

are easily vandalised and stolen, need batteries replacing and cannot be used in high-power applications,’ he says. ‘However, if one takes the latest developments into account, most of these assumptions can be disproven.’

In particular, the economics of solar power are improving.

‘Performance has increased dramatically but the biggest change is the price point,’ says Stephen Scott, chief design officer of Scotialight, whose Sunmast is a solar-powered column designed to feed energy back into the grid. In terms of output power, ‘since we started in 2008, the watt peak per cell was 3.2Wp to 3.4Wp for a monocrystaline cell. Now, it’s more than 4Wp in good or even cloudy ambient light. In 2008/2009 it cost €4 per watt peak. Today, that’s about €1 per watt peak and solar is becoming much more cost competitive.’

The efficiency of the light source and the solar panels is the real nub

of the problem, says Iain Macrae, Thorn Lighting’s head of global lighting applications management. ‘I think the significant step will be in solar panel efficiency. Claims for recent panels of 25 to 35 per cent improvements are good, but it is still expensive.

Increases in LED efficacy combined with continued reductions in cost make the lighting more viable. Recent research into solar arrays suggests we may see the breakthrough in the next few years.’

Lindenberg adds that the sector will become even more competitive when PV modules with higher conversion efficiency become commercially available. ‘These new modules will reduce surface area, wind resistance and weight. Highpower street lanterns will then enter the realm of solar street lighting, too.’

He predicts that solar LED street lights will become available as retrofit kits for existing columns, with lightweight

aluminium supports or enclosures, and will use Smart Energy Management (SEM) to provide lighting throughout the night, in all seasons.

In Gerrard’s Cross, Buckinghamshire, solar lighting start-up Sun Air Sustainability (SASEnergy) has been field testing a retrofittable ‘all-in-one’ solar-powered luminaire containing 12W LEDs, solar panel and lithium batteries. The sofar unnamed luminaire was trialled in December 2013 and January 2014 as a street light with wattages from 5W to 30W, but will be marketed as a ‘community’ light that can be mounted on shorter 4m poles, for use on railway platforms, car parks and pathways, says director Ray Noone.

The luminaire’s all-in-one design is partly intended to overcome visual clutter from separate solar panels and large battery packs. Using what is claimed to be the most efficient solar cells currently available, it has motion

sensors to conserve energy. ‘I would rather leave it on all night but it won’t work like that here. You need the biggest battery pack to make it work in the UK. We tested it in Dubai for three months and it was fine but we’re not in Dubai,’ says Noone. Nevertheless, ‘we have something that is affordable, is energy-saving, looks good and, hopefully, has plenty of applications we haven’t thought of yet.’

For the time being, ‘with current lighting technology, the amount of power that would be required to achieve normal street light brightness with reliable dusk-to-dawn operation in the UK would require far more solar panels than you could practically fit on a lighting column and an impractically large battery bank,’ says David Hibbs of Marlec, which makes the Green Column, a hybrid luminaire that combines solar and wind power, and is used mainly for footpaths, playgrounds and car parks.

‘At open sites the brightness and/ or operating times can be greatly improved with the inclusion of a wind turbine which can potentially deliver significantly more power in the winter than a solar panel,’ says Hibbs. ‘An alternative approach for locations which already have mains connection can be to use solar panels mounted on the lighting column to feed power back into the grid during the day, offseting some of the power that the lamp is drawing from the grid at night.’

Franks’s view is that while solar street lighting could be viable ‘when combined with wind turbines... that would require planning consent and potentially noise assessment.’ He also says that from a council’s point of view using solar power with a ‘push-pull’ technology that both charges from and returns energy to the grid, ‘is only likely to be progressed under “go green” type projects currently, as these are “high risk”.’

Lighting Journal March 2014

Solar power

Push-pull technology in particular could tip the scales for solar-powered lighting by changing the economics of on-grid energy use. ‘The grid connect has been a slow process in a number of European countries,’ says Scott.

‘But in the UK we have been analysing a hybrid solution and discovered that by having a one-day cycle battery aboard the mast, even in winter the first four hours of darkness would be covered by the battery so we can flatline energy prices into the future.’

Lindberg includes in his list of the benefits of solar-powered lighting ‘no grid connection charge, no waiting time for grid connection and immediate operation, no cable trench excavations, no cable cost, no metering, zero electricity cost and zero carbon emissions for life span.’ But even with smarter use of better technology, the main stumbling block to solar street lighting in the UK might remain the quality of what it is intended to replace.

‘The aim has to be to get the overall cost and efficiency to a point where the energy saving benefits

Thorn’s new Suncyl range (see below)

outweigh the cost,’ says Macrae.

‘This is especially interesting when you consider the costs of power distribution in remote locations and payback here can be very quick.

As we have very good power

distribution in the UK, and relatively low night-time energy costs, this approach is less attractive. But where we have remote communities with limited generation capacity there has been significant interest.’

LED cost analysis

ago) with a medium base can likely be relamped today with an improved technology, but without specialist intervention or replacement.

What about integrated LED fixtures? That downlight you specified last year – can you get the same boards for it today? What about next year? What about in 15 years?

What about 30? As an industry are we setting ourselves up to be hated in a decade? Will our clients be in increasingly drab spaces in 10 years’ time, unable to afford another capital refurbishment but trapped because their luminaires are unmaintainable?

s you head home this evening, cast a glance at your surroundings as you travel through transport infrastructure – perhaps a train station or two, a bus station, or even an airport. As you look around you, assess the age of the luminaires that you see.

Many products from the 1990s?

1980s? Even the 1960s are still well represented.

Upgrading these technologies may well achieve cost savings, although 1990s T5s remain at better efficacy than LED products, where optics are not required.

But will the savings over the next five years justify the disruption and capital cost of refurbishment now, more than waiting five more years for LEDs to mature? What are the factors that suggest waiting? What suggests we should go now?

The past two years have been interesting – we’ve seen the acceptance of LEDs as mainstream luminaires, and an increasing belief that they are an established technology. As designers, it’s very easy to specify products, and put an argument to the client – we cherry pick the arguments that best serve getting the design to move forward.

But have we, as an industry, lost our bearings, lost our focus on what matters in projects?

It is my belief that one key factor is missing in the maturity of luminaire technologies, and that is the issue of maintainability – not over five years, but over 30. We have built up a degree of complacency that five years – maybe 10 – is a pretty good life for LEDs. The challenge, however, comes at the end of that time. Any luminaire with a medium screw base lamp can take pretty universal technology – a luminaire supplied in 1984 (30 years

Analysis In 2012 Lux Populi was commissioned to write a comprehensive lifecycle cost analysis of a scheme developed for an airport terminal. The brief was to explore LEDs as an optional alternative to the existing scheme, designed in 2011, and comprising a small number of metal halide luminaires and a larger percentage of linear T5 fluorescents.

The following discussion explores what we learned about the key factors and those elements of the comparison that created substantive technological advantages in one direction or another. The project was context-specific, but many aspects translate to other project types, and the conclusion is clear – we have to give serious thought to the question of maintenance sustainability of design.

With the myriad variables potentially considered within the realm of a project, the list of factors to be taken into account must be tailored to specific client needs, project type and relative ability to control, measure or influence outside factors. Throughout our study the following considerations were included, discounted and assumed respectively:

A

l Included: Energy costs and labour costs, capital equipment costs, replacement luminaire, ballast and lamp costs, warranty periods and types, maintenance equipment and labour costs, circuit operating hours, dimming benefits, practicalities of access and, last but not least, architectural impacts l Discounted: Tax and energy incentive programmes, inflation, disposal, rare earth metal trading issues, dimming, normalisation for opportunity costs l Assumptions: fixed energy

costs, current projections of natural resources and technology growth, constant labour rates, market inflation.

Although clearly not factual, holding these constant provides a basis for comparison of multiple technological approaches without being distracted by macroeconomics Further considerations that we included that may be worth consideration on other projects included: future capital improvement costs, circulation time associated with travelling through site (time from noticing a luminaire had failed to problem resolution, including walk time, lift drive time), equipment purchasing paths and so on. In essence, the selected factors are those that either affect the differentiation of products, or those that are consistently predictable.

One interesting example of unpredictable transitory conditions was the spike in global rare earth metal prices, due to political situations in China. The effect on prices of fluorescent lamps was substantial, adding 30-50 per cent to the cost of a tube. However, on LEDs the price impact was not clear. The spike in phosphor prices was blended into the rapidly falling price of the LED chips and modules themselves. Additionally, at the current price point of LEDs, phosphors are a much smaller percentage of the module price than they are of fluorescent lamp costs.

Other cost elements that are transitory include taxes and incentives.

Incentives are often driven by political expediency or have limited time or cumulative value. As such, any incentive included should be punctual, or rooted in ongoing law, rather than as temporary programmes.

Durations and methods of analysis The duration of analysis must be appropriate to the installation life.

Retail projects have very short installed lives – in prime locations often just five to seven years. As such, the performance of a lighting system in year 12 may be irrelevant.

On the other hand, a quick look at installations in infrastructure locations will demonstrate systems that are 30 to 50 years old, albeit with many components, and even all luminaires, changed out, sometimes several times. Even retail, however, is much slower moving in regional and secondary locations.

30 years total cost (exchange rate US$1 = 0.60p)

This analysis used 30 years as a design life, a goal that matched the existing ages of lighting equipment in the other terminals of the airport.

Two methodologies were carried out simultaneously to ensure the integrity of the study. The first treated each aspect of maintenance in isolation and looked simply at the mean cost and frequency of any given action, simplifying the analysis. That is to say, that each element is averaged.

Lamping cost divided by the number of years between lamp changes renders an averaged annual lamping cost.

The second study, year by year, examined the costs incurred (lamping, electrical costs, maintenance costs, materials and so on), looking at both bulk replacement cycles and off-cycle spot replacements. This means that, for example, bulk ballast replacement costs are not considered in the first few years until the age approaches the MTBF (mean time before failure) of each ballast type. By looking in each given year, redundant actions can be eliminated – for example, where full fixtures are replaced, there will be no need for cyclical replacement of ballasts in that year, they are replaced as part of the luminaire cost.

In this way, the first analysis method overestimates costs, and fails to recognise the timing of any given cost. It is useful simply for roundnumber assessment of the scheme.

The second, more detailed analysis is both more accurate and useful, and allows interventions where the entire system is changed to be timed relative to major maintenance operations, a planning advantage key to future upgrades. The former analysis, however, provided a check on the validity of the assumptions underlying the more detailed analysis.

Bringing together so many factors in the analysis gave a great advantage

Lighting Journal March 2014

to in-year cost analysis, and provided useful information about the relative advantages of warranty life. It also dramatically differentiated between durations of analysis in early periods of the project. LEDs with five-year warranties clearly distort the average cost analysis method over the first few years. That said, in airports, material and labour warranties are not nearly as valuable as at first they seem. The simple cost of getting a technician on to an airport with tools, and supervising them at all times, makes irrelevant the saving of using external

its implications. Ultimately, LED luminaires require large cost components to be changed out as the LEDs reach the end of their operating lives. Whereas with fluorescent every 30,000 hours one is changing out a ÂŁ5 (or less) tube, with the LEDs the operator must change out the LEDs themselves. Spot replacements are also significant.

More important, with LEDs it’s often necessary to contact the factory for a module replacement. On small quantities, the cost of administering this through a purchasing department (and with reference to specialist electricians removing and identifying components needing replacement, and interfacing with manufacturer technical support) becomes very significant. A simple replacement spec code is rarely available from manufacturers. Keeping attic stock reduces these costs, but brings costs forward and freezes technological advantages of development.

In returning to the analysis 12 months later, one of the most interesting net shifts in LED lighting costs involved two related aspects: the change from integrated LEDs to

labour provided by the warranty against in-house labour.

Uncovering hidden benefits When broken down into cost components, the variation of costs between LEDs and foregoing technologies is most extreme when it comes to the total bulk replacement costs. LED fixtures cost more than standard lamp technology for a variety of reasons.

Most critical is the proprietary nature of the LED module and

modular/replaceable components, and the subsequent change from luminaire-manufacturer driven LEDs to OEM components. The first step dramatically drops the cost of reaching the end of LED life from the full replacement cost of a luminaire to that of a component. The second, much more dramatically, reduces the challenge of sourcing that component and increases the probability of finding the replacement.

Generic modules such as Xicato, Fortimo and so on provide a

LED cost analysis reorderable component that may be held by distributors in the region, as opposed to sourcing from the factory.

This reduces lead time on orders, improves reliability and cuts cost.

That said, as such generic modules flood the market, the number of current models that will continue to be supported over the coming three decades (the design life of this project) may rise, but not as a significant proportion of the modules available, and will take time to prove their longevity on the market. An enormous number of the products now on the market will likely be unsupported. GE recently discontinued (and eliminated existing stock) of its Generation I LED modules and, inevitably, others will do the same, leaving products unsupported into the future.

It would be safe to assume that any specific model of module made in the hundreds of thousands will be supported, but what about a module made in just tens of thousands? Will there be sufficient market demand to keep them in production over 30 years?

Nevertheless, this evolution to modular LEDs, with appropriate storage of spare modules, addresses much of the cost of integrated LEDs. In punctual luminaires, generic LEDs are now becoming gradually standardised. Will Xicato vs Helion vs Fortimo become the next Beta/ VHS debacle? There remains a major deficit of generic modules for linear luminaires.

Also interesting in our analysis is the common multiplier of life between lamp/module technologies and the control gears. Many LED control gears have an MTBF of around 75,000 hours (where manufacturers are even prepared to provide the information). This is twice the life of many LED modules and, as such, every second relamping engenders a more expansive maintenance cycle.

The costs of such replacements are dramatically affected by the modularity of the power supplies and how generic they are for future proofing. Generic output and standardised form factors would go a long way to establishing confidence, a fact that is lost on most luminaire manufacturers today.

Spot replacement of lamps due to unexpected failures is a large cost component as each failure requires individual access, unlike bulk relampings which can be coordinated to enjoy best economies of scale.

exploration, it can be seen that the spot replacement of LED modules is a significant cost factor, far and away more expensive than spot power supply replacements.

Fixture replacements occur essentially with equal frequency for all technologies as these failures are more likely to be due to site conditions

easily changed like-for-like due to the increased likelihood of stock being on the shelf, whereas LED products are often obsolete before they are delivered, so continuity is not good.

Reviewing our results, analysis shows costs structured over time and by component. Year-on-year costs vary, giving the graph of cumulative

than technology issues, with fittings often damaged during other ceiling access operations, painting, water leaks and other incidents. The cost is relatively significant simply due to the fact that full luminaires are being changed out as a result but, comparatively, there is little difference between technologies.

The small difference in cost is due to the capital cost of the replacement luminaire, with labour and access time essentially the same. More proven technologies tend to be more

costs a slightly noisy appearance over 30 years; however, the overall gradient of cost is clear and consistent. Peak cost years occur when relamping or fixture replacement costs fall, particularly when several circuits occur in a common time period. Overall, the first five years see a lower gradient for LED costs, but it then turns upwards to its relatively constant rate over the following years. This is due to the longer warranty periods of LEDs and the period to their first relamp. Once the warranty period passes, the

LED cost analysis operating costs return to the mean.

The annualised cost represented here is the year-mean for each scheme over 30 years. The differences in costs are clear, and follow the 30-year cumulative cost curves, representing the mean gradient of the graph.

Instructive in understanding the conclusions of our report was the substantial difference in the split of costs within each system. The maintenance cost includes the labour and materials bundled, with labour being a dominating component within maintenance – lamps are relatively cheap compared to the labour of installation. By contrast, LED driven schemes are extremely expensive to maintain due to the material costs associated with the fixture replacements as the bodies become outdated. It is this component that drives key cost differences over the life of an installation.

Key messages With findings from updated and new studies in 2013 we have concluded that full factor analysis is going to be key to genuinely understanding the lifecycle costs of products, though in future we may be able to return to a lamp-life and energy use only comparison of technologies. The factors considered by manufacturers’ sales materials simply do not answer the question, ‘Does this product serve my client’s interests?’

To truly serve our clients, we have to consider the realities of maintaining products over the life of the installation. Lighting installations are one of the most expensive components of any building both initially and in maintenance. At the end of the day, we can anticipate much of a client’s intent, but should we be baking in planned obsolescence?

Worse, what about unplanned obsolescence?

Standards

Often oversimplified, not always scientific, standards are no substitute for good design, argues Malcom Innes

Shadow Tree by Mike Bolam for the Between Two Worlds art project: 150m of footpath through the forest were illuminated with textured light produced by 1W LEDs shining through young pine trees. ‘This kind of high contrast solution is the antithesis of most urban realm lighting, but none of the 3000 visitors tripped over the shadows’

Standards

here are two ways to look at lighting standards and codes of practice. One view is that the standard is a quantification of what is actually required for optimal vision.

The other way is to see a standard as a description of what is normally done by others. The two descriptions are definitely not the same.

We all tend to view standards as some kind of scientific quantification of what is essential, when sometimes the standard is simply a reflection of common practice. I know, because I have written standards like that.

When working for Speirs and Major on the Terminal 5 project at Heathrow Airport, we were tasked with drafting new lighting standards for the airport’s rail stations. This document had to encompass all the existing standards that each of the train operators (British Rail, London Underground, Heathrow Express, CrossRail and Heathrow’s own Tracked Transit System) used at the time.

‘Although lighting guides and standards are yet to catch up, darkness has now became an explicit weapon in the armoury of lighting designers’ At some point in the past, some of these documents may have been based on scientific research about what was necessary for lighting, but they were mostly just descriptions of how the different companies normally did things. The resulting T5 Rail Lighting Standard was therefore a compromise between what we as designers believed would create good lighting and what the multiple existing standards demanded.

All around the world there are temporary light art events that take audiences into dark forests and landscapes which are brought alive by colourful lighting. There is no lighting standard for these events, but if one did exist, it would most likely be built on common practice. Most of these light art events are actually delivered by production companies with a background in theatre and live events.

Being temporary installations, the normal approach is to use equipment from hire stock. Traditionally, this

meant lighting up the forest with 1kW tungsten halogen PAR cans, coloured with theatrical gels. Even where annual events now mostly use LED luminaires, they are using equipment designed to mimic the output of PAR lamps. The results can be spectacular, and spectacularly overlit.

Audiences love these events and they are always very popular. It’s partly because people see this as a safe way to explore the forest at night – we want to experience the rural darkness that is missing from urban life.

When I was asked, as an artist, to create a month-long night trail through a remote valley in the Cairngorm Mountains in Scotland, the Between Two Worlds event, I decided to ignore the ‘standard’ PAR can and theatrical hire equipment approach. Instead I wanted to create a design that was based on giving the audience a real feeling of darkness and providing the minimum amount of light required to illuminate the features of the trail.

The specification and design was decided, not by doing what others normally did, but by a process of actively testing on site.

The approach I took was to try and ensure maximum visual adaptation to darkness. I knew myself that it was possible to walk the path safely at night with nothing more than the very dim glow of the night sky (starlight or clouds very faintly glowing from the nearest urban areas some 80100km away). To identify which trees would be lit, I used a 1W LED torch for testing. Against such low levels of ambient light, this was enough to illuminate the whole tree. In the end, where the normal approach would have used a 1kW PAR can, our project mostly used 3W white LED sources to uplight fully grown pine trees.

We were so successful at illuminating the 3km trail with low output sources, that we actually caused a problem for the power supply. The power requirements were so small that the generator sets believed there was no load attached and tried to shut themselves down.

Ironically, the solution from the installation company was to hang a dummy load of a single blacked out PAR lamp on to the circuit so that the generators continued to operate.

Because darkness was an integral part of the design for the project, what seems on paper as tiny quantities of light were all that was required to create the lit effect. It did not

23

look underlit, but it did allow subtle modulation between the lit and unlit areas. It allowed the maintenance of a level of vision adapted to the ambient conditions. None of the 3000 visitors said that it was too dark.

While the essential lighting ‘task’ for the Between Two Worlds event was quite simple – being able to safely walk along a path – a lot can be learned from the experience of working with such low levels of light.

The principal lesson is for us to remember how adaptable the human visual system actually is. If you only read lighting standards for interior spaces, you might believe that our visual system works over a maximum range of around 10:1 (the difference between corridor lighting and drawing office lighting) and that vision will become seriously impaired if there is more than a 2:1 difference in light levels across a task area.

However, the self-referential nature of standards and codes of practice tends to forget the reality of natural light – the light for which our visual system is best adapted.

Between a patch of direct sunlight and the dappled shadow cast by leaves, there can easily be in excess of a 7:1 difference. We do not tend to trip over because we walked into the shade of a tree. Even on an overcast day, a modest-sized interior space, such as a classroom, with a wall full of windows can experience a variation of natural light greater than 10:1 over the depth of the room. Again, we accept this visually because it is natural, but our lighting standards would not accept this for electric light – why not?

When standards fail Although it is rarely the intention of codes of practice and standards to quash creative solutions, by their very nature, lighting standards tend to lead to standardised solutions. In any field of design there are those who want or need a quick fix, and standardised lighting solutions are often seen as shorthand for compliance. The rationale being that, if it has been done before, it must be the right way to do it. However, standardised solutions, when repeated over and over, tend to reveal design shortcomings that were not envisaged at the time of writing the lighting standards.

A classic example of this process was acted out in office lighting in the UK throughout the 1990s. The increasing reliance on computers in

Lighting Journal March 2014

24

Standards

the workplace prompted a shift of emphasis in lighting practice. The principal manuals for compliance chasers were the CIBSE series of Lighting Guides. Although these documents were guides to good practice (the clue was in the title) and not a legally established standard, many people treated them as if they were law.

In an effort to reduce potential glare problems in workplaces full of computer monitors, LG3 recommended that light was focused tightly downwards so that horizontal and low angle light did not reflect in display screens. Different kinds of display equipment uses were categorised as Category 1, 2 or 3 depending on the maximum luminance deemed acceptable at angles approaching horizontal viewing angles.

The rush to compliance resulted in lighting manufacturers producing luminaires that were badged as being LG3-compliant and including Cat 2 louvres (even though there was no official badging scheme). The highvolume, low-design installers saw the badged luminaires as a timesaving alternative to designing a lighting system. The result was a plague of speculative office spaces with high illuminances on the working plane but little or no light on the vertical surfaces

and no direct light on the ceiling. The lit effect was commonly described as a cave and even though it complied with the office lighting guide, the resultant

Standardised lighting approaches in a world where there is no standard building or location is making things too simple and is no substitute for good design’ lighting schemes were universally hated by users and linked to a wider ‘sick-building syndrome’ that was used to describe workplaces that were not fit for purpose.

The end result of so many installers following the letter of the guidance was the worst kind of lighting and, eventually, the wholesale scrapping of the guidance. The replacement lighting guides specified a minimum proportion of light on the vertical walls and on the ceiling plane – completely turning the whole basis of the previous guidance on its head.

As CIBSE now says, ‘the term

“Category 2” is no longer used by CIBSE. It was used to describe a particular design of luminaire (light fitting) that could be employed to prevent reflections of the luminaire on the display screen. Unfortunately, in doing so, these luminaires can produce a gloomy environment if used on their own without consideration of surface reflectances. In most offices, particularly where modern computers with bright screens are used, such reflections are not likely to occur and therefore it is not necessary to specify this type of luminaire.’ 1 Nevertheless, it is still possible to buy Cat 2 luminaires, even though their use will not satisfy the requirements of the revised office lighting guide.

The majority of lighting standards and codes of practice are created with the best intention, to ensure a minimum quality of lighting for the end user. However, the complexity of defining all the possible ways of producing good lighting means that standards tend to simplify solutions to make them more likely to be applied.

As Albert Einstein said, ‘Things should be as simple as possible, but no simpler’. Standardised lighting approaches in a world where there is no standard building or location is perhaps making things too simple and is no substitute for good design.

Dunblane Museum, exhibition design by EDO Design, lighting design by Malcolm Innes: ‘Museum environments often show how little light we actually need to safely navigate even unfamiliar spaces. With lighting focused on vertical display surfaces, illuminance on the floor and luminance of the floor are often very low. If this rarely seems to cause a problem for visitors, why do we require so much light on the floor in corridors?’

While the lighting for this office space may be designed to reduce potential glare on display screens, the lit effect in the room is very poorly considered.

A very dark end wall and messy spill light on the right hand wall do nothing to inspire confidence that the installers cared about the end users of the room. The luminaire is not a particularly cheap build and includes uplight and downlight from one linear fluorescent lamp and Dali dimming with Osram control gear. It has a mirrored louvre for the downlight and reeded optical diffuser for the uplight component. As a student project, a similar space was dramatically improved by removing all the optics from the fluorescent luminaires. The final installation retained luminaires containing bare lamps and added a vaulted soffit of white card above the luminaires to capture and diffuse the uplight component. The lit effect was greatly improved for the users of the space by distributing the light more evenly on the working plane, and around other visible surfaces. Despite the exposed lamps, the vaulted reflector also reduced the luminance contrast around the light source itself making for a much more comfortable visual experience. In this case, a lowtech, architecturally integrated lighting solution worked much better for the end users than the high-tech luminaires used in the wrong place.

With optics apparently designed for very wide spacing or very low ceilings, this luminaire is a bad choice for this installation where suspended ceiling height is around 3m. The working plane (desk height) is just below the wall-mounted trunking. It is clear from the pattern of light on the wall that the luminaire optics have a very focused beam at about 30 degrees each side of vertical. In some installations, this could be useful. However, in this installation the luminaire spacing means that the peak output from adjacent lines of luminaires overlaps at working plane height. The result is that, at desk height the peak output is centred between luminaires and is twice as high as it needs to be – more than 1000 lux. The luminance distribution in the room is also affected by the poor luminaire choice, with a range of 4:1 in the narrow band from 0.7m to 1.7m above floor level. Most of the upper wall and the suspended ceiling plane are visibly much darker than the working plane. The lit effect is reminiscent of all that was bad about office lighting in the 1990s.

Lighting Journal March 2014

Standards

Perhaps, instead of standardised approaches, we need a rights and responsibilities model for lighting: the end user of the project has the right to good lighting, therefore the designer has the responsibility to deliver a lighting scheme that is fit for purpose, aesthetically enhances the architectural space in a way that is not detrimental to the user and does not waste energy.

To prove compliance, we usually calculate and measure illuminance (in lux or foot candles) within the lit space, even though we actually see luminance. In an attempt to be easily applicable by installers, do lighting standards and codes lead us to measure the wrong thing?

Designing light, or designing darkness When commissioned in 1998 to carry out a lighting strategy to tackle some of the poorly lit streets and lanes in Cambridge, Speirs and Major surprised the client with its solution to some areas of perceived darkness – reduce the lighting elsewhere.

While the received wisdom would be to add luminaires in the ‘dark’ areas, a survey of the sites revealed that, of themselves, they were not too dark. However, the problem was that they adjoined very brightly lit main

thoroughfares. Slightly reducing the illuminance near the junctions would reduce the contrast and increase the perceived brightness of the lanes, without the need to add any more lighting equipment.

This approach to also planning darkness as part of lighting design was embodied in subsequent master planning projects by Speirs and Major, notably the Durham Light and Darkness Strategy2. Although lighting guides and standards are yet to catch up, darkness has now become an explicit weapon in the armoury of lighting designers.

Whatever the ‘efficacy’ of any new lighting technology, sometimes this kind of intelligent approach to design problems can achieve even more effective savings by not adding any lighting at all – surely the most sustainable solution.

The response to questions of lighting sustainability should be based on achieving efficiency through the application of good design principles in preference to simply ticking the box that says we have used ‘efficient’ sources, or adding lots of technology to improve lighting ‘efficiency’.

As eco architect Howard Liddell described it, ‘eco-minimalism is the antidote to eco-bling’3.

Road lighting 1

Tunnel vision Jill Entwistle reports on two projects involving major roads. First, a controversial scheme for an arterial route landmark in Canberra that has turned around its reputation as a black spot

Lighting Journal March 2014

Road lighting 1 masts with 4000K metal halide floods keep clutter to a minimum on the deck. The solution provides an area of 9300sqm free of traditional lighting poles, but delivers a well-controlled light to where it is needed.

‘This methodology is probably the first of its kind in a tunnel lighting application, enhancing the built form and creating a luminous floating deck,’ says Baki Ulas. ‘Keeping the deck and wall surfaces free of light sources provides ultimate driving comfort and safety.’

It has also produced a practical maintenance benefit. ‘In addition to providing glare-free, strobe-free and shadow-free lighting, a key strength of the solution lies in the operational aspects,’ he adds. ‘Unlike traditional lighting which requires lifting equipment and closure of lanes for maintenance, the lighting here is serviced safely and very easily by one individual, and with no disruption of the normal traffic flow.’ This also includes the facade lighting which can be serviced from the bridge deck.

f you are going to take a more unorthodox lighting approach then you might play it safe by not picking a site notorious for accidents.

However, an original scheme for a major infrastructure project in the Australian capital of Canberra has transformed a traffic black spot into a safer, more attractive landmark.

Statistics show no recorded accidents within the year the new Kings Avenue Overpass has been open, compared to an average of two accidents a week, the highest in the city, before the project was undertaken.

The bridge straddles the major route connecting the airport to the civic centre and parliamentary district.

Unlike traditional tunnel lighting, the underpass is lit from within the ground only using Bega 4000K fluorescent uplights for the underpass soffit.

‘It was very controversial – there are obviously strict standards in underpass lighting,’ says Emrah Baki Ulas, associate with Steensen Varming, which was responsible for the underpass and bridge lighting scheme. ‘It involved laborious lighting calculations and modelling, as well as onsite testing with actual luminaires.’

As well as the uplighting to the underpass, there are two other key elements: coloured lighting to the bridge facade and masts for the upper deck. DMX-controlled Litesource RGB LED strips are used for the facade (around 140 1.1m units). These are concealed in the railing and reflectors at the top of the facade.

Moving in the light circle An ingenious solution for cyclists at a busy intersection has put the area on the map

s befits a cycling-orientated nation, instead of just grudgingly giving cyclists a couple of feet of roadway, the Dutch build a spectacular structure for their benefit. The Hovenring bicycle roundabout was commissioned by the city council for the Heerbaan/ Meerenakkerweg intersection, marking the entrance to the cities of Eindhoven and Veldhoven. The development of a nearby housing estate meant the intersection needed changing in order to cope with growing traffic.

The council likes to avoid cyclist underpasses and didn’t want a level crossing roundabout, so they asked Dutch bridge specialist ipv Delft to come up with an alternative.

The technically challenging 72m-diameter, 70m-high circular cable-stayed bridge was the eventual solution. And, of course, this being Eindhoven, home of Philips, the lighting is an integral part of the structure’s impact.

The bridge comprises a pylon, 24 steel cables and a circular bridge deck made of steel. The cables are attached to the inner side of the bridge deck, where the bridge deck connects to the circular counterweight. The key lighting element is integrated into the circular deck. The space between the counterweight and the deck is fitted with

After testing against LEDs, T8 fluorescents were selected for the ring of light

Lighting Journal March 2014

aluminium louvres, translucent sheeting and long-life TL-D fluorescent lamps (58W Pracht Apollo SR T8 fittings).

‘These light sources were tested against LEDs, and were selected because they generated a clearly visible ring of light at night,’ says ipv lighting architect Rob Kruizinga.

‘Together with the illuminated pylon, the ring of light ensures the bridge’s spectacular appearance.’

The pylon is lit with Philips Color Kinetics Color Reach floods, uplighting from a recessed, vandal-proof landscape position. LED lighting (3000K) is integrated into the railing. This illuminates the bridge deck and ensures facial recognition of the bridge users. Philips Decoflood MVF 616 fittings (60W CosmoPolis lamps) are attached to a cable framework between the pylon and bridge deck, and mounted on the inner surface of the circular counterweight to illuminate the intersection underneath. Peripheral roadway lighting comes from Philips Iridium SGS 253 fittings. www.hovenring.com Client: Eindhoven City Council Design and lighting: ipv Delft

IDNOs

Supplying a better solution Neil Fitzsimons looks at proposed changes to allow a single inventory for unmetered supplies using IDNOs

I

n the November 2013 issue of Lighting Journal, Alan Jacques looked at the rising popularity of Independent Distribution Network Operators (IDNOs) and some of the consequent issues that faced local authorities. Mention was made of the IDNO workshop at the Glasgow Professional Lighting Summit where representatives of these operators advised that they had become acutely aware of an unintentional consequence of the billing arrangements set up between host distributors and IDNOs when it comes to unmetered supply (UMS) connections. This consequence incurs rising administration costs on all UMS customers – particularly local authorities.

It seems unfair that UMS customers are often forced to trade multiple metre point administration numbers (MPANs) and absorb the costs associated (supplier charges, additional administration required, and so on). These additional costs merely allow the host DNO to bill the IDNO for Use of System (UoS) charges for using their part of the network to supply the IDNO’s end customers. The UMS customer gains no benefit at all from having to register multiple MPANs – in fact quite the opposite.

Given the comparatively low

Lighting Journal March 2014

volumes of UMS connections to IDNO networks (when they are considered relative to DNO connections) and the associated low UoS revenues, the extra administration appears to outweigh the benefit of a potential increased accuracy in splitting the UoS charges between the IDNO and the DNO. The increased administration costs that the local authority could be exposed to due to the existing DNO/ IDNO unmetered supply arrangements has led to LAs refusing to complete highway adoption agreements where developers have opted to make connections to an IDNO. This practice distorts competition as developers face additional obstacles in achieving highway adoption when connecting to an IDNO rather than a DNO network.

Increased administration costs that the LA could be exposed to due to the existing DNO/ IDNO unmetered supply arrangements has led to LAs refusing to complete highway adoption agreements The existing arrangements between DNOs and IDNOs means that there are different tariff rates depending on whether the embedded network is connected at 230/400V, 11,000V, or 33,000V and above.

This is because a 240V connection will employ significantly more of the DNO’s network than a connection at 33,000V. To differentiate between the connected voltages, an inventory that a customer provides to an IDNO has

to be split by the IDNO across the various voltages and an MPAN applied to each. Potentially a local authority customer with connections to multiple embedded networks connected at multiple voltages could have up to approximately 180 different MPANs and, as a consequence, 180 bills for the street lighting.

While this number of MPANs is technically possible, realistically this level is unlikely to be reached for a single customer. However the costs incurred even for a small number of MPANs should not, in our opinion, be borne by the end customer for no perceived benefit.

The IDNOs are currently seeking to amend these arrangements by proposing an industry change to the regulatory framework that governs these processes.

Readers of Alan Jaques’s article (and attendees at the 2013 summit workshop) will be aware of a consultation last year that was issued under the Distribution Connection and Use of System Agreement (DCUSA).

At the time of Alan’s article the outcome of the consultation was being reviewed and a way forward agreed. The overwhelming view of the local authorities was that they should be allowed to maintain a single inventory for UMS energy billing purposes which contains their current host DNO equipment and any additional equipment on an IDNO network. This would make managing IDNO unmetered equipment much more straightforward and remove any extra administrative costs/ burdens and so on.

IDNOs are now about to submit a ‘suite’ of change proposals – the intent of which is to make the required amendments to the Balancing and Settlement Code (BSC) and the DCUSA that will in future enable all UMS customers to opt to trade their unmetered supply connections

IDNOs

on IDNO networks under the host DNO’s MPAN. The proposed changes will affect the following regulatory documents: • BSCP520 (Unmetered Supplies Registered in SMRS) The intent of this change will be to make changes to the BSCP to enable UMS customers to trade all of their unmetered supplies connected to both DNO and IDNO distribution systems under a single inventory/MPAN • DCUSA – amendments to the National Terms of Connection A change will be required to ensure that there are appropriate arrangements in place to cover the DNO and the customer connected on the IDNO’s network, for example tripartite agreements • DCUSA – a single discount factor for all UMS IDNO tariffs This change will focus on the interdistributor charging arrangements laid down in DCUSA. The change recommends the creation of a single IDNO discount factor for UMS connections regardless of the DNO/IDNO boundary network level. These changes should not affect the UMS customer’s tariff

It seems unfair that UMS customers are often forced to trade MPANs and absorb the costs associated. The customer gains no benefit at all – in fact quite the opposite

The proposed changes will deliver improved service to all UMS customers (particularly local authorities) by simplifying the current administration process for unmetered connections. The simplification of this process will allow developers to award contracts to IDNOs without the fear of highway adoption issues. This in turn will benefit competition in provision of connections and distribution services to distribution networks.

with the aim of progressing the proposals through the relevant industry code governance process.

The more relevant and collaborative the representation on working groups, the more assurance the final decision makers – in other words Ofgem – will have that public interest, effective consultation, the impact of the change and the objectives of the relevant industry have been adequately considered and addressed when it comes to reviewing the final change report.

This is the test taken into consideration when approving or rejecting a change to the various codes. It is therefore extremely important for UMS customers who are feeling the burden of the multiple MPAN issue, especially local authority street lighting officers, to voice their opinions through these working groups. The important thing is to have your say and be involved in changing highways and infrastructure for the better.

Alan Jaques’s earlier article also raised other perceived issues with using IDNOs to provide connections; those issues will be dealt with in subsequent articles.

Why should a UMS customer get involved in these changes?

Each of these change proposals will have working groups established

Now you see it...

The tower that makes its presence felt through a disappearing act

T

he thing about most totemic towering structures is that people like to light them up so they can show them off at night.

Tower Infinity in Seoul, South Korea, however, is a bit different.

Here they are using lighting to make it vanish. Billed as the world’s first invisible building (probably a little touch of hyperbole there), it will pull off its disappearing trick with the help of the LEDs on its facade.

The glass-encased 450m tower structure has been designed by architect Charles Wee, president of US architectural firm GDS Architects, and will be constructed near Incheon International Airport just outside Seoul.

The skin of the building will feature linear LEDs and a series of 18 weatherproof cameras strategically integrated within the diagrid mullion system. These will project realtime images of the area around the building on to the structure’s reflective surface, so that the tower will appear to become transparent when the projectors are turned on.

The tower, which will include restaurants, a cinema, three observation decks, a roller coaster and a water park on the 110,400sqm site, will not always be self-effacing.

The LED fixtures also allow it to become a more conventional video facade to broadcast special events or advertisements, and act as a focal point for visitors arriving at Incheon.

How it measures up to the world’s highest towers

It will be sixth on the list of the world’s highest towers when completed – behind Tokyo SkyTree, Guangzhou’s CantonTower, Toronto’s CN Tower, Moscow’s Ostankino Tower and Shanghai’s Oriental Pearl – and will have the third highest observation deck in the world.

Lighting Journal March 2014

But as the game of who’s got the biggest one is getting a bit out of hand, it probably makes sense to adopt a different strategy for getting your tower noticed – even if that relies on not being able to see it. ‘ The tower subtly demonstrates Korea’s rising power in the world

by establishing its most powerful presence through diminishing its presence,’ says the GDS website.

‘Korea will have a unique position of having the “best” tower by having an anti-tower.’ There’s a perverse logic in that. www.gdsarchitects.com

Meeting demand Feedback is a vital element in keeping pace with members’ training needs, says Dave Burton, VP education

No one would argue that the rate of technological progress in lighting equipment has ramped up considerably during recent years and, over the two years during which I have been VP education, keeping pace with the changes has been challenging for all of us in the profession.

Most people, of course, look at LED developments and see this as the sole major advance, but what is often forgotten is that LEDs are merely another light source – unless they are used in an appropriate way, their real benefits will not be optimal and lighting quality may suffer too. Just as with any of the equipment we have available to create lighting schemes, a thorough knowledge and understanding of what’s available in the market, and the limitations and benefits, are key to using LEDs effectively.

When the structure of the ILP was changed a few years ago, one of the main aims was better to align membership services with members’ needs and, in the area of education, this has meant among other things, broadening our training course offering. So last year, over a very short period and guided by comments from members, we established a Fundamentals of LEDs course.

The new course was an immediate success and is now being repeated regularly. It has brought in new presenters as well, broadening the pool of expertise we have available to us.

The whole process of running such courses – which have to stand on their own feet financially – is reflective, in as much as we invite delegate feedback and review the content every time it’s going to be presented. This ensures

Lighting Journal March 2014

that we are always conveying up-todate information appropriate to our members’ needs.

As LED lighting technology is maturing and more of us are routinely using it in our work, providing training purely at the fundamental level may not be sufficient. Again, based on comments received from the membership, we are now looking at the options for more advanced levels of training in this area.

As LED technology is maturing, and more of us are using it, providing training purely at the fundamental level may not be sufficient Another education success story has been the extension of regional training activities. While the ILP has always offered these to some extent, they hadn’t reached some parts of the UK and last year, due to demand from the Scottish Region, we ran pilot courses in Scotland. I’m pleased to say that the uptake was very good and we will continue to offer local training where there is demand and it is commercially viable.

I urge any members who have ideas for training courses or changes to the way we run our present offerings to contact me to help ensure the institution is keeping up with what you need professionally.

There is, of course, so much

more than just LED development that we need to consider, and for which training is essential. One of the reasons the pace of change has been so great in lighting technology is that we now have access to equipment linked to the consumer electronics market. Nothing changes faster than computing and communications technology, and a significant amount of lighting equipment now contains more computing power than the Apollo spacecraft had for getting to the moon and back.

This is good news in as much as it has driven down in real terms the cost of central management systems (CMS) for highway lighting. In the interior lighting world, features such as Dali are now commonplace and no self-respecting lighting designer would contemplate not using some form of controls as part of an effective, efficient lighting scheme.

With control systems too, a thorough understanding of the capabilities of the technology is necessary in order to work with it effectively. This is a further area in which we are actively looking to develop training packages based around what our members tell us they need. It’s down to you, the members, to tell us where you think we have gaps in our training offering.

Last but not least, the Exterior Lighting Diploma (ELD) course, which continues to be very popular, needs continual review to ensure it’s up to date. We are coming to a review point for ELD now, so if you have any strong views on this course, now is the time to let us know. vp.education@theilp.org.uk

Industrial Lighting Systems V-Spring

V-Spring 3m telescopic lighting poles are primarily for walkway lighting in commercial and industrial settings, and are designed to improve safety and reduce cost in maintaining lighting at height. Incorporating an internal vertical spring to help take the load when the column is raised or lowered, they are adjustable between 1.5m and 3m. With a single bolt fastening, a lighting maintenance worker can single-handedly lower the lighting pole for lamp changes or maintenance. According to ILS, even allowing for the cost of the V-Spring, immediate savings of more than 50 per cent could be realised, and future maintenance costs could be cut by more than 90 per cent by avoiding the expense of hiring equipment to maintain a fixed pole from ground level. The poles come in three different models: hot-dipped galvanised, aluminium and stainless steel, plus the option of a weather-protected coating for any environment. They are designed to withstand a wind rating of 320mph and can be mounted on any walkway, hand rail or wall. Supplied fully assembled and pre-wired, the poles offer 360-degree rotation of light fittings. www.ilsuk-ltd.com

YLP column

A smart career move James Miles gives six reasons why you should join the YLP

F

rom the outside, it can be hard to see why you would want to be a Young Lighting Professional member. With work piling up and pressure to get the job done it seems hard to justify spending time out of the office, so why bother? However, becoming a YLP member is a must for those who want to make an impact in the lighting industry.

First, it’s about knowing your industry – attending ILP/YLP events is the perfect way to get to know key people within it. You can gain a real insight into how the lighting industry operates and, more important, who drives the wheels of motion forward.

This fundamental knowledge will help your company grow and target the right people.

Even if you have a non-sales role this is useful as it will help you prioritise the right projects for the right people, and get a better feel for how your projects are progressing.

It is amazing how much more can be learned about a project face-toface rather than over the phone as people tend to be more open and relaxed at events.

Second, it’s a way of becoming known in the industry. ILP/YLP events are a good way to progress your own career by building relationships with other lighting professionals. These occasions are a great way to promote both yourself and your company.

Despite social networking and advances in digital media, personal,

face-to-face relationships still play a major role in lighting as people prefer to deal with who they know and trust.

Getting your face known can open up new doors, while strong personal relationships with the right people will improve your performance within your current role and may also open up new job opportunities.

A third advantage is the support that you can get from your peers – events bring together expertise and knowledge from all different aspects of the lighting industry. This opens up a tremendous opportunity to get advice and opinions from the best and brightest all under one roof.

If you have an unusual project, or are having trouble with a particular persistent problem, an ILP event could be the place to resolve the difficulty with advice from others who may have a different viewpoint or know of a solution because of their position within the lighting industry.

Support is also available for those who are undertaking one of their modules for the ILP Exterior Lighting Diploma, with many people at the events having completed the diploma and some even teaching the modules.

ILP events are a perfect place to get answers you need, in an atmosphere that would be impossible to replicate anywhere else.

Another factor is updating your CPD. Today, nearly all employers have a continual professional development requirement for their staff to ensure

that they are competent within their role. ILP technical paper days are a perfect way to add hours to your CPD with papers presented on the latest topics. One of these sessions can offer up to eight hours of CPD and they are generally offered free of charge.

Getting time out of the office to attend will save your company time and money as conventional professional development seminars are often chargeable and don’t provide as many hours towards CPD. ILP members also benefit from being able to register their attendance and CPD hours on the ILP website and, once logged in, can keep a permanent, printable record of the papers heard.

Finally, there are the social aspects of membership. Along with the papers being presented, the YLP will often include an opportunity to socialise at the end of the day to help our members get to know one another and have a bit of fun too. These include activities such as mountain biking, zip lines, or, for the less intrepid, a visit to the pub with a lighting-based quiz.

Would you like to have your voice heard by the lighting community?
