O

ne of the challenges you face as a journalist when attending LuxLive is simply drawing breath. There are normally so many conference tracks to choose from – and at last November’s event it was eight – all potentially fascinating and informative (and sometimes overlapping) that, if you’re not careful, you spend your time simply racing madly from one talk to the next.

For me, therefore, it was something of a relief to find myself with a few minutes to take stock and reflect while waiting for a speaker in the ‘Property Technology Live’ conference track. I had arrived early for a presentation on ‘How IoT [the Internet of Things] lights can help manage meeting rooms’, which meant I caught the end of a panel discussion around ‘IoT, privacy and data in a GDPR world’.

What struck me was less the debate itself – it was interesting but was wrapping up and already in the Q&A section – and more the fact, quite clearly from both questions and answers, that there was as much a mix of people in the audience from data, technology and software backgrounds as there were pure lighting professionals.

And that, for me at least, was a repeating theme. Earlier in the day, for example, Peter Earle, business development manager for Philips OEM Technology, had talked in a panel discussion about IoT and emergency lighting of IoT being ‘the next thing after LEDification’ – and look out for a report on that in next month’s edition.

Various informal conversations I held around the stands also highlighted how many individuals and organisations were increasingly recognising the need either to employ, buy in, or collaborate with experts in these technology fields. Or, given the size of some of these software and tech businesses, finding themselves the target or secondary partner in these sorts of relationships.

In the long run, of course, this poses some rather profound questions about the future dynamics, relationship and even ownership of lighting as an industry. Is lighting as a discrete, expert profession at risk of being subsumed within or consumed by technology juggernauts? Is this something to be worried about or kick against; or should we all just sit back and accept it as an inevitable (and probably lucrative) evolution? Indeed, if it means lighting has the potential to become the 21st century’s go-to transactional and data gathering digital infrastructure, is this even a price well worth paying?

I don’t pretend to even start to have the answers to any of this. But it is perhaps a debate that needs to be had within the industry, both within the ILP – and I’d be really interested to hear any views or letters on this for publication – and more widely.

Lighting and nightscape assessment

ASSESSING NIGHTSCAPES

6

The increasingly multidisciplinary nature of landscape and environmental assessment means it is imperative that landscape and lighting professionals work collaboratively to assess the visual effects of a project on the landscape, especially night-time lighting impacts

By Karl Jones

L

andscape professionals (usually landscape architects) are regularly required to produce an array of environment, landscape and impact assessments as part of their role.

Best practice guidance on how to undertake the assessment process is largely specific to each environmental aspect, and generally relies on professionals who specialise in each particular area to undertake their own specific assessment. This process, naturally, should facilitate improvements to the design of the plan or project to avoid or minimise adverse effects (especially those that are deemed ‘significant’). www.theilp.org.uk

But there will often be overlaps in the assessment areas (for example the effects on ecology from lighting) adding another level of complexity to the process. The plan or project co-ordinator will often try to manage the iterative design and assessment process to incorporate the various requirements, but will be reliant on the knowledge of the experts in their fields to work together to identify and mitigate the adverse effects, through good design and specification.

This article intends to look at some of these different assessments, particularly those where lighting can be a factor, and from there address how lighting and

landscape professionals can work more closely together to ensure projects progress in the most seamless and impact-free manner.

The overarching process of Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) can be incredibly complicated. The effects of plans or projects on the environment and people are numerous, and will inevitably be a combination of positive ( beneficial), neutral and negative (adverse) in their nature. As a landscape professional, the process of identifying which of these effects are potentially important in the decision-making process

February 2019 Lighting Journal

(or ‘significant’) requires a sound understanding of the various: • Sources, types and characteristics of impacts that will occur; • Types, locations and sensitivities of the ‘receptors’ that will receive the impact; and • Types and levels of effects that will manifest from the impact on the receptors, both in their own right and in combination with other potential or existing impacts and effects

GROWING NEED FOR COLLABORATIVE WORKING

As already highlighted, to work through this process landscape professionals will often rely on other professionals to undertake their own specific assessments, and there may often be overlap between assessment areas that will need to be co-ordinated. The residual effects (in other words after mitigation measures have been incorporated) are then required to be communicated in an effective manner, to both the decision-makers and the public – a challenge in its own right.

What this all serves to illustrate is that, as our knowledge of effects on the environment and people develops through research, and professionals’ awareness of the wider considerations related to, but beyond, their core area of expertise increases, the need for more effective interdisciplinary working has grown.

One such area of interdisciplinary overlap is that between lighting and landscape professionals, and an understanding of each other’s perspective can help to define overlaps and result in more comprehensive assessments and holistic design solutions.

As well as EIAs and SEAs, landscape professionals are regularly required to produce Landscape and Visual Impact Assessments (LVIAs), Landscape Character Assessments, Landscape Sensitivity and Capacity Studies, Green Infrastructure Strategies, and Tranquillity Assessments, to name only a few. In undertaking LVIAs, landscape professionals assess the effects on two individual (but interrelated) aspects:

Changes in views (and visual amenity) result in effects upon people, whereas ‘landscape’ is an environmental resource (and receptor) in its own right.

WHAT IS LANDSCAPE?

The European Landscape Convention (ELC) defines landscape as: ‘…an area, as perceived by people, whose character is the result of the action & interaction of natural and/or human factors.’ Importantly, landscape does not only relate to the countryside, it includes areas such as new towns, industrial areas, seascapes, and the urban fringe.

The landscape at a locality can be described through a combination of visible elements (for example vegetation and buildings present), and non-visible elements (for example geology, smells and cultural history connections). Overall, this creates an experiential association with a place, affecting its perception (this being most influenced by the views gained of a landscape). The sources of

influences on the perception of landscape do not need to be present at the locality, they can also be more remote (for example a mountain backdrop, distant views of urban areas).

Together, the combination of the various contributing landscape characteristics result in the description of the landscape character of a locality. This in turn

7 tq Landscape value has many contributing elements, including scenic beauty, tranquillity, cultural associations, and

conservation interests, and may be reflected by landscape designations. For example, Areas of Outstanding Natural Beauty – such as Painswick Beacon in the Cotswolds, below, or National Parks, such as Dartmoor, top left – will naturally have more stringent planning policies attached

This reflects the desirability of a landscape’s characteristics such as, for example, its dark skies status

gives it an identity, which will likely have a number of associated key characteristics.

Changes to this (for example through new development) are more likely to result in what would be assessed as being a ‘significant effect’, and thus would be a material consideration in the decision-making process.

ASSESSMENT OF LANDSCAPE AND VISUAL EFFECTS

Landscape character and changes to landscape character (and views) have usually most often been assessed and described in relation to the daytime landscape; the landscape character at other times of the day often being poorly considered – but this is changing. It is becoming more widely recognised that the description of a landscape and the experience of being there immediately after dusk, during the night and immediately prior to dawn (or the nightscape character) are likely to be different in many ways to the description for the daytime, and from place to place, and that this has been poorly considered in landscape character assessments and so on.

Assessment of landscape effects takes ‘landscape value’ into account to determine landscape sensitivity to change. This reflects the desirability of landscape characteristics (for example dark skies) and the acceptability of their loss to different stakeholders (people with different perspectives).

Landscape value has many contributing elements, including scenic beauty, tranquillity, cultural associations, and conservation interests, and may be reflected by landscape designations (for example www.theilp.org.uk

Areas of Outstanding Natural Beauty (AONB) and National Parks) with more stringent planning policies attached. But all landscape character areas have intrinsic landscape value of differing degrees and for different reasons. In relation to nightscapes, examples relate to vibrant cityscapes which may be transformed, and come alive at night through spectacular lighting, and conversely a starlit sky in a tranquil area may have inspired poets, songwriters and artists in relation to a place providing an additional valued cultural aspect to a locality.

A ‘landscape of natural light’ is typified by the influence of natural light from the sun and lunar cycles, clear air and dark skies undisturbed by artificial light. ‘Dark skies’ have become an increasingly rare and valued resource in the UK and are a key characteristic of areas where they still exist, providing important contributions to perception of tranquillity and ‘wildness’. Dark skies (for example in AONBs) can be adversely affected by sources of light tens of kilometres away, which may bring cross-boundary effects into consideration.

The majority of populated areas have a night-time character that lies somewhere between the darkest of skies to the brightly lit city. This absence of dark skies removes a key component of our natural environment and part of a healthy, enjoyable, uplifting landscape that forms our habitat. It is a natural and cultural asset worthy of preservation where it is, and restoration where it is not (like other forms of pollution). So ahead lies the opportunity, through interdisciplinary

working between planning professionals, landscape professionals and lighting professionals to work together to reverse adverse effects, restore darker night skies and improving environmental quality.

More specifically, the challenges in relation to landscape character and views are to: • Prevent (or at least minimise) artificial lighting sources at one location (where it may be appropriate for that location’s landscape character) exerting adverse effects in other landscape character areas (for example through effects on sky glow at that location, or by affecting perceived ‘remoteness’, through ‘urbanising’ influences); and • Ensure that artificial lighting does not have adverse effects on the landscape character where they are located (either directly from the presence of the lighting itself, or indirectly via resultant knock-on effects, such as reduced tranquillity, loss of dark green infrastructure or reduced contribution of visible starlit skies)

NIGHTSCAPE STRATEGIES

Within this, Environmental Zones provide a loose framework to guide lighting aims. But zoning in this way is a blunt tool in relation to LVIA, in that it ignores distant effects of lighting, including that from reflected light and visible light sources. A much more comprehensive option is to work in an interdisciplinary way (with landscape and other environmental professionals) to fully encompass environmental considerations, for

But, increasingly, they need to be working collaboratively with lighting professionals to better understand the relationship between lighting (especially night-time lighting) and environmental impact

example through nightscape strategies linked to local plans.

Whilst there are many factors that contribute to quality of life, the adverse effects of artificial light and lighting on landscape should not be overlooked. So LVIA goes hand-in-hand with place-making and can have a positive role to play, through interdisciplinary working, in helping lighting professionals specify the right type and amount of lighting to take into consideration the: • Defining of a place or reinforcement of an existing landscape character; • Provision of fresh perspectives (for example a key landscape feature seen at night versus during the day); • Achieve a ‘net gain’ in the quality of the environment overall; and • Provide sustainable multifunctional outdoor spaces for the 24-hour economy The LVIA process is separate from that undertaken for Lighting Impact

Assessments (LIAs). Nevertheless, both landscape professionals and lighting professionals should be encouraging one another to work together to ensure that the inter-relationship between the two aspects are understood by the project co-ordinators, and taken into account at the start of a project, as this may not be immediately obvious to non-specialists.

Landscape professionals should therefore be encouraged to inform the lighting professionals about the receiving environment (in terms of landscape and visual receptors and the outline aims in relation to night-time effects), but will then need expert input from lighting professionals on: • Lighting impacts (in other words the change experienced by the receptor) via the effective understanding and communication of these; and • Design solutions

The assessment of the effects should be undertaken by the relevant suitably qualified professional (for example a landscape architect for LVIA, and a lighting professional for LIAs) using input from one another on the impacts and receptors, in accordance with their relevant guidance, such that the iterative design and assessment process provides the best multi-aspect design solution.

The joint overall aim should be to ensure that the quantity, quality, location, visibility and timing of light, has been sufficiently considered and optimised to minimise adverse effects on night-time environments and receptors at and distant to that location, and to maximise the positive opportunities through great lighting design.

‘THE ROAD TO HELL IS ILLUMINATED WITH

GOOD INTENTIONS’ When it comes to lighting roadways, one academic makes the case that, as lighting professionals, we need to remember light distribution is more important than light level

e all know we cannot see in the dark. So, naturally, as lighting professionals we intuitively know that vehicle crashes with pedestrians and other vehicles can be reduced by illuminating our roadways.

And our natural instincts tell us, if some illumination is good, higher levels of illumination are even better. Indeed, recommended light levels are systematically higher where there is a greater likelihood of vehicle-to-vehicle or vehiclewww.theilp.org.uk

to-pedestrian conflicts. In North America, for example, for ‘medium pedestrian conflict areas’ the Illuminating Engineering Society (IES) recommends an illuminance of 2 lux in the vertical plane, defined by the front face of the crosswalk, and 10 lux for ‘high pedestrian conflict areas’ (Illuminating Engineering Society 2014) [1].

Unfortunately, however, a five-fold

increase, or even a 50-fold increase in illumination levels often has very little effect on visibility. What matters much more than light level is light distribution as it affects the contrast of hazards.

Consider for example night-time lighting for a crosswalk. Figure 1 shows renderings of a crosswalk illuminated by two lighting systems to 10 lux in the vertical plane, as recommended by the IES for ‘high pedestrian conflict areas’ (Illuminating Engineering Society 2014).

b Figure 1. Two renderings of a crosswalk, both illuminated to current IES standards of 10 lux in the vertical plane defined by the front face of the crosswalk (Illuminating Engineering Society, 2014).

Both renderings include illumination from automobile headlights at 150ft (46m). The left rendering (a) is for a conventional 250-watt, highpressure sodium, pole-mounted luminaire.

The right rendering (b) is for a four-bollard LED lighting system operating at a total of 28 watts of power. As can be readily appreciated by comparing the two renderings, the contrasts of the pedestrians on the right (b) are superior to those on the left (a) even though both lighting systems meet current IES standards. p

The illumination from one lighting system is produced by a conventional, polemounted luminaire (left) while the other is produced by four bollards positioned at the four corners of the crosswalk (right).

DRIVERS’ HEADLIGHTS

One thing that is often forgotten in roadway lighting standards is that drivers always have operating headlights, which can affect the visibility of the pedestrian, so both renderings include illumination from the driver’s headlights.

Figure 2 overleaf shows the visibility levels (based on the relative visual performance, RVP, model by Rea and Ouellette, 1991) of pedestrians in dark (10% reflective) clothing positioned at different points in the crosswalk as a driver approaches the crosswalk with headlights operating [2].

Figure 2a, meanwhile, shows how the conventional lighting system affects the visibility of the pedestrians to an approaching driver.

Depending upon location within the crosswalk, the pedestrians may be highly visible (green surfaces correspond to an

RVP > 0.9) or, potentially lethal to a pedestrian, nearly invisible (red surfaces correspond to an RVP < 0.7).

In contrast (deliberately playing on this word), the visibilities of the pedestrians are never compromised with the bollard lighting system in figure 2b because the distribution of the light always ensures the pedestrians, no matter what clothing might be worn, are always in high positive contrast.

In other words, the luminance of dark or light clothing is always higher than that of the roadway in the background, with or without headlight illumination.

The reason this is true is that the bollard light distributions illuminate vertical surfaces while keeping the horizontal background surfaces dark, thus rendering the pedestrians in high positive contrast. It should also be noted that the light distributions from the bollards limit glare to oncoming drivers from either direction (Bullough et al., 2010) [3].

Figure 2. Quantitative comparison of pedestrian visibility in the two renderings from figure 1 at 10 lux (top row, a and b) and at 100 lux (bottom row, c and d).

Visibility is defined in terms of relative visual performance (RVP) from Rea and Ouellette, 1991.

The RVP values are based upon (i) a target size of 44 μsr (1sq ft at 150ft) and a contrast of black pants against the crosswalk pavement having a reflectance of 7%.

The driver’s age is assumed to be 40 years. Green surfaces in all graphs correspond to the ‘plateau’ of visual performance where RVP > 0.9, whereas yellow (RVP = 0.8-0.9) and red (RVP < 0.8) surfaces correspond to the ‘escarpment’ of visual performance.

The visibility of pedestrians, even wearing black clothing, is always high (RVP > 0.9) with the bollard lighting system whereas a pedestrian can be very difficult to see at some locations in the crosswalk with traditional pole-mounted lighting, even at 100 lux. p

from 10 lux to 100 lux, a very large increase in operating costs and one that conventional thinking might demand in an attempt to improve safety after some unfortunate pedestrian was struck in the crosswalk.

As can be clearly seen, however, increasing illuminance level by a factor of 10 makes little if any functional difference for both lighting systems.

There are two logical conclusions from the examples illustrated in figures 1 and 2. First, illuminance is not what the lighting standards should be primarily concerned with – contrast is much more important. Therefore, light distribution, including headlights (Rea et al., 2010), should be the primary consideration in roadway lighting standards.[4] Second, because the distribution of light

drives the contrast of hazards, and thereby their visibility, only relatively low levels of illumination are needed on the roadway.

Not only do low light levels on the roadway reduce operating costs, they also minimise collateral effects of light pollution without compromising safety.

So, with apologies to Samuel Johnson: ‘The road to Hell is currently illuminated with good intentions.’ We need to rethink how we light our roadways, remembering light distribution is more important than light level.

It’s a defence in actions for damage for non-repair and provides the defence in the fact you have looked at the circumstances, that you understand your network, and you have looked at how you will manage that network and go forward. And part of the UK’s Roads Liaison Group’s new Well-Managed Highway Infrastructure: a code of practice looks at how you can evidence and provide the defence. www.theilp.org.uk

So, why the change, why the new code?

As Andrew Warrington highlighted in last month’s edition of Lighting Journal, the previous Well-Lit Highways was fairly prescriptive. It lacked flexibility for consideration of your local needs – it was one-size-fits-all. It had a lot of recommendations, but it was not really riskbased in its approach.

What we’ve looked at now is the consolidation of the three existing codes to create a more risk and asset management-based approach for how we look after our highway lighting asset. We look at reactive, time-based, condition-based and riskbased management of that asset and how we go forward.

We go back to the old line I have been talking about for many years: ‘if you don’t know what you have, you can’t manage it’.

February 2019 Lighting Journal

p

Westminster City Council is one local authority that has been working hard to ensure it is compliant with the new code

Therefore, it is a matter of understanding what you’ve got, the condition it is in, how you understand that condition and how you manage it going forward based on your own requirements.

EVIDENCE THE PROCESS

The challenges the code brings are for you to evidence the process; this is part of your defence under the Highways Act. Evidence of why you consider this process to be suitable for you and your local authority, taking into account your own needs.

And the skills and competencies of the people who are involved in making that decision and undertaking the work and going forward.

It also brings few opportunities, because it is about looking at something tailored to your own local needs and the budget you have available. This strengthens your asset management and improves your efficiency.

You can look at understanding where the issues are, and therefore you can target what funding you have got where it is actually needed, based on the actual asset condition. And this gives you the evidence to go to your councillors/powers that be with that evidence to help your budget-setting and funding processes and to deliver good business cases.

Andrew and I have been working with Westminster City Council, and this article is going to focus on what we have been

doing with the council, at a practical level, to help it to become compliant.

First, we’ve done a number of workshops, we’ve looked at the service consideration. We’ve looked at the tasks that are undertaken. How do those tasks map into the requirements of the recommendations in the Code of Practice? What recommendations actually relate to the tasks? What already exists that we can use and develop, and which might already be suitable? And how do we want to prioritise this process? Which do you ‘pick off’ first, rather than simply saying, ‘ooh, there is an awful lot here to do’? How do we look at the priorities and which ones we need to do first?

We’ve recorded a lot of the processes through flowcharts and good supporting narratives. We looked at the service, service aspects such as safety inspections, luminaire clean, inventory management and so on. We’ve looked at the recommendations that we feel are applicable out of the 36 with regard to the lighting service.

Then we’ve looked at each of those tasks and decided which recommendations fit with that task. And then we’ve looked at what do we have at the moment that covers that need? And what do we think are the actions we need to look at in order to bring that information up to the required level? Is it perhaps already at the required level, just not documented? We

Asset management

went through the whole service. But, actually, it wasn’t a process that took too long to sit down and do; it was just about getting the right people in the room for half a day and explaining the background.

In terms of advice, what I would say is identify the processes, but don’t make them too complex. The more complex you make it, the more evidence you have got to supply and the more narratives you have got to have about why you are doing something. I’m not saying just make it one box, but look at if it can be stripped down to what is fair and reasonable, as otherwise you can make a lot of work for yourself; but you have to make the right amount of work.

COMPETENCY AND TRAINING

18

Look, too, at the competency and training of the people involved; the first thing the client did was send people off on courses to understand their own requirement as councillors and officers under CDM. We did get a few jaws dropping as they realised that just making a decision potentially brings you in as a designer, so they decided ‘we need to go away and understand this’.

Once we had got the flowcharts, we looked at those and how we could expand on that to provide some narrative. So for every box shown, we have a process activity and we’ve identified who is the role holder, how things are going to be reported and advised through to the local authority.

You also, of course, need to make sure such evidence is available, should it be called into question.

You’ve also got to look at risk within the various aspects. We all have a different requirement of risk. Highways England, for example, has very low tolerance of risk – if a column falls down it could cause an accident or close the road. Conversely, if a column falls down in a parish council, it is going to cause a problem, but there might not be m a ny p e o p l e around and

www.theilp.org.uk

u

Under the new code it is important to look at the competency and training of the people involved in your asset maintenance

so they may have a lower risk and be happier for the column to be in a slightly worse state of repair. So it is a balance.

But we do have to understand that failure to maintain can result in serious injury or death, and that will lead to damage, and the main cost here is civil claims, which can be really, really expensive. So it is a matter of looking at how happy you are with risk; your local priorities, road hierarchy, finance and affordability – they all influence a tolerance of risk and what you will feel, as your authority or your clients, will be acceptable. You need to go away and ask the question and understand that.

And common-sense needs to fall into how you do that, of course.

If we have a luminaire hanging, the chances of it falling off are few and far between. But the consequences of if it is does and hits someone are dire. So it might only score four, but you would still want that done in a two-hour response time because that is quite critical. It is about understanding the condition of what you’ve got, monitoring that and taking it forward through the asset process.

The code, ultimately, helps you to understand the structural condition of your columns and luminaire supports. But from there is can help you to understand how well your lighting is performing against standard, against

crime levels in your area, and against energy efficiency.

You can look at how you can develop an approach where you can actually weight these and prioritise these so you can focus on this evidence as to where you need to go and spend your money, at street or column level. This can help you to put together your budgets, your business cases, to go forward to your powers that be. And that helps to develop a resilient network.

Finally, if you have got a resilient network, if you understand the processes being looking at, have got the flowcharts, the narrative and the evidence, you can go back to our legal responsibilities under the Highways Act – and then you have your defence.

The ‘Illuminated River’ public art project

20

I

LP volunteers are set to play a key part in the creation of the ‘Illuminated River’ public art project that will light up the capital’s London, Cannon Street, Southwark and Millennium bridges from this summer.

The ILP in December put out a call for ‘the lighting opportunity of a lifetime’ – volunteer placements on the project, work on which was due to begin in earnest last month.

The ILP’s team of volunteers will experience first-hand the development and installation of this major art project in London.

It is expected the volunteers will attend one or two project briefings and then around four to five on-site programming nights, providing practical support to the artist Leo Villareal during his late nighttime digital sequencing work on and around the bridges.

It is a real opportunity to see at firsthand how an artist of his calibre programmes the sequencing of the light artwork on bridges.

The volunteers will also share their experience, creating content for the ILP to share with ILP members and the public.

The project has been progressing since it was announced by London mayor Sadiq Khan back in December 2016, with two major announcements taking place in the run-up to Christmas.

First, in November the Illuminated River Foundation announced that site works would begin in January, as part of www.theilp.org.uk

Work was due to be begin in earnest last month on the ‘Illuminated River’, the ambitious public art project to illuminate up to 15 iconic London bridges. Signify, formerly Philips Lighting, is set to be the project’s connected lighting partner, and a team of ILP volunteers will also be at the heart of the action

the artwork delivered by Leo and architects Lifschutz Davidson Sandilands.

The free and publicly accessible light installations on the first four bridges, as outlined above, will then be expected to be launched this summer.

‘SCULPTURAL AND SYMBOLIC LINK’

Eventually up to 15 central London bridges in total will be illuminated, stretching from Albert Bridge in the west of London through to Tower Bridge in the City, ‘unifying them in a single artwork and delivering them as a sculptural and symbolic link across the capital’, as the foundation has said.

The activation of each bridge will be phased, with a further section due to be completed next year and the whole project due to be finished by 2022, subject to funding being secured.

The second announcement, also in November, was by Signify, formerly Philips Lighting, that it will be the ‘connected lighting partner’ for the project.

Signify will therefore be supplying its Interact Landmark system and its Philips Color Kinetics LED luminaires for the bridges, delivering dynamic, artistic lighting effects via its centrally managed software.

Signify will also provide lifecycle services to remotely monitor and manage the connected bridge lighting for the next ten years.

More than 22,000 connected Philips Color Kinetics LED light points, capable of

displaying more than 16 million colours, will be used to create dynamic lighting effects on the bridges.

Neil Mendoza, chair of the Illuminated River Foundation’s board of trustees, said: ‘A tremendous amount of work has been done since the winning team of Leo Villareal and Lifschutz Davidson Sandilands was announced some two years ago.

‘Much of that work has been undertaken in collaboration with organisations up and down the river, including one of the largest and most detailed planning processes London has seen.’

Of the volunteering programme, Jess

Gallacher, ILP operations manager, added: ‘The Illuminated River project is a wonderful example of the effect light can have on our society and we are thrilled to be able to give our members such an outstanding opportunity.’

The 15 bridges due to be illuminated, assuming full funding can be secured, are: London Bridge, Southwark Bridge, Cannon Street Bridge, Millennium Bridge, Blackfriars Railway Bridge, Golden Jubilee Bridge, Waterloo Bridge, Blackfriars Bridge, Lambeth Bridge, Vauxhall Bridge, Westminster Bridge, Grosvenor Bridge, Chelsea Bridge, Albert Bridge, and Tower Bridge. www.theilp.org.uk

RENAISSANCE THINKING www.theilp.org.uk

The Scrovegni Chapel in Padua, Italy, houses an immensely valuable and popular collection of frescoes by Renaissance master painter Giotto. And it is all now illuminated by an adaptive, IoT-enabled LED lighting system designed to protect as well as enhance its priceless artworks

By Piergiovanni Ceregioli

T

he Scrovegni Chapel in Padua, Italy, is home to an array of incredible works of art by the Renaissance painter Giotto di Bondone, more commonly known just as Giotto.

In particular, the chapel contains a fresco cycle completed in 1305 that is widely regarded to be one of the masterpieces of Western art. All the internal surfaces are covered with Giotto frescos, including the walls and ceiling, in what is a stunning display and, naturally, a prime tourist attraction for the city.

Known in his day as an artistic innovator, what Giotto would have made of the latest connected ‘Internet of Things’ (IoT) LED technology is anyone’s guess, of course. But this is precisely what has been used as part of a ‘perceptive restoration’

project, which is designed to enhance the illumination of the frescoes as well as to help to protect them from glare and wear and tear.

The new lighting system integrates LED luminaires, innovative environment sensors designed by an Italian start-up called WiSense, and internet protocol software.

In the initial phase of the project, sensors designed specifically for the chapel were set up to measure the variations in natural light. Once this data was processed, a dynamic lighting system was then installed, using an algorithm to adapt the lighting to any changes in the environmental conditions. iGuzzini Palco C.o.B and Laser Blade luminaires with a high colour rendering index were used to ensure a better perception of the colours, especially in terms of the warm tones (yellow-orange-red), which enhance the gold leaf used in the halos as well as other features.

ADJUSTABLE TONES

Using products with tuneable white technology has enabled white light tones to be

dynamically adjusted as the intensity of natural light varies during the day. This means that, since the project has been completed, visitors have been able to enjoy the frescoes’ chromatic complexity more clearly, irrespective of the time of day when they visit.

One of the challenges was that the asymmetrical distribution of the six windows on the southern façade of the chapel produces an uneven distribution of sunlight.

However, with the new system, these variations can be detected and transmitted to the control system. This then adjusts the luminaires accordingly, in compliance with European standards regarding exposure limits for the conservation of artworks. By zeroing UV and IR emissions, the system also helps to avoid any risk of damage to the precious artworks.

Monitoring and control are based on a wireless sensor network (WSN) architecture entirely developed by university researchers. This is mainly composed of sensor nodes directly connected to the Internet via a Border Router. Every node is part of the same µIPv6 mesh network and www.theilp.org.uk

of a common web browser.

This communication model facilitates the integration of constrained devices in line with the development of the web and of IoT applications.

The constituting nodes are sensing nodes (SN), which are able to measure the overall level of incoming light (natural plus artificial) in a number of locations within the chapel’s inner walls, and control nodes (CN), which interact with the DALI devices embedded into each luminaire.

An innovative SN was developed for this project, in order to monitor the perceived level of light. It incorporates a sensing unit, a processing unit and a communication unit. The processing unit is able to compute the Correlated Colour Temperature (CCT) and the illuminance (EV) of the light sources.

The communication unit provides radio connectivity both toward the CN for the real-time transmission of the CCT and EV values and toward the internet for the data storage into a remote database.

The CN is composed of a communication unit and a bus adaption unit, which ensures DALI compliance. The first unit receives and elaborates data from the SN, while the latter unit sends DALI commands on the bus.

CONCLUSION

p Figure 2. The monitoring and control system adopted to interact with the Scrovegni Chapel’s lighting system

wireless communicates via the IEEE 802.15.4 protocol (868 MHz). The wireless mesh network is formed by low-cost, lowpower consumption, self-organised and self-configurable IPv6 addressed nodes.

Building an ad-hoc wireless architecture in this way, one that is fully compliant with the IoT requirements and compatible with pre-existing systems, allows lighting professionals to increase the functionality of a conventional lighting system.

The architecture is based on the IEEE 802.15.4 standard for physical and data link layers. The communication model is based on a UDP (User Datagram Protocol) www.theilp.org.uk

traffic type over µIPv6 (micro internet protocol version 6). The address mapping from µIPv6 to IPv4, the fragmentation and reassembly mechanisms, and the header compression are guaranteed by the 6LoWPAN (IPv6 over Low-Power Wireless Personal Area Networks) protocol.

RPL, the Routing Protocol for LowPower and Lossy Networks, is used to achieve a high network lifetime and a very low network set-up time. Finally, the Constrained Application Protocol (CoAP) is implemented at the application layer, allowing a user to interact with the wireless sensor nodes of the network by means

In conclusion, the value of an implemented solution such as this is its versatility and scalability with reference to the number and density of nodes, the network typology and the variety of sensing or actuating units embedded within the nodes.

The WSN designed for the Scrovegni Chapel’s lighting system consists of a real IoT solution that allows communication between individual sensors and the connection of each of them to the internet.

The functionality of the system can be further enhanced through the integration of additional sensors. Each piece of environmental data is stored locally and remotely, thereby enabling both realtime control as well as storage of the acquired data and its long-term analysis (for example for the creation of predictive models).

Finally, the possibility to equip the LEDs with IP drivers could fully complete the IoT paradigm, making each lighting element an internet user directly connected to the network, without the need for complex and expensive gateways.

MAKING GOOD 26

The energy efficiency benefits of LED are well-recognised, and will often be the key business case for overhauling or refurbishing an industrial unit. But there are other compelling arguments lighting professionals can use to encourage a switch to LED, including improved employee productivity and wellbeing and better health and safety

By Gary Bennett

T

he energy efficiency case for LED lighting is beyond debate. When you consider the impact of the longer lifespan of luminaires, coupled with the reduced energy consumption and maintenance requirements, LED technology can reduce a manufacturerâ&#x20AC;&#x2122;s spend on lighting by 80% over the lifecycle of an installation, according to the Green Investment Bank [1].

But energy saving is only part of the equation. And this is one reason why it is important to review the lighting requirements of UK industrial facilities. As well as the energy savings offered by LED technology, there are significant additional benefits for manufacturers and their employees that arise from the design of new industrial lighting schemes.

These benefits come in areas of significant www.theilp.org.uk

importance for manufacturers, such as on-site safety, employee wellbeing and even business productivity â&#x20AC;&#x201C; all areas that help to drive profitable business growth.

THE STATE OF PLAY

Contrary to widespread perceptions, manufacturing in the UK is in strong health. According to the EEF (the organisation that represents UK manufacturers) the UK is currently the worldâ&#x20AC;&#x2122;s eighth largest industrial nation. If current growth rates continue, the country will be a top five industrial nation by 2021. More than 2.7 million people thrive in the sector and industry accounts for more than 45% of UK exports [2].

This is not to say the industrial sector does not face significant challenges, particularly in terms of the uncertainty

around and post-Brexit. Competition for the right people will increase, tariffs could have an impact on the long-term growth of the sector and Britain still faces an historic issue around productivity compared to many of its European counterparts.

The UK lags behind EU countries such as Germany, France and Italy in this area as well as other industrialised nations such as the US and Canada, according to the OECD. This has a consequent negative economic impact on wages, profitability and future growth [3].

All of this suggests British manufacturing will need to do more than ever to maintain its competitive advantage in the future.

Increasingly, industrial companies are looking for new opportunities to drive efficiency, reduce cost and deliver a safer, more harmonised environment for UK workers.

February 2019 Lighting Journal

CORRECT COLOUR TEMPERATURE AND EXPOSURE

It is estimated that people receive around 80% of their information visually, through their sight, demonstrating the critical role industrial lighting plays in maintaining employee welfare [4]. This means, naturally, creating safe working environments that illuminate wayfinding markers, machinery and factory workspaces, as well as emergency exits.

This matters for manufacturers. Several have been subject to significant fines (tens of thousands of pounds) because poorly designed and executed lighting has caused risk and safety issues.

Manufacturers, distributors and logistics operators therefore need to zone in on issues such as applying the correct colour temperature and exposure to lighting, so workers can do their job more effectively and reducing glare for sites focused on logistics where vehicles are in constant operation.

Lighting also has a role in maintaining employee wellbeing – both physical and mental. A study conducted by the American Society of Interior Design revealed that 68% of employees complain about lighting at work. Poor lighting at work causes eye strain, fatigue, headaches and stress, leading to increased numbers of employee sick days and less job satisfaction [5].

The UK manufacturing industry is one of the highest employers of EU workers – with 10% of employees coming from the continent. Recruiting and retaining the right people could become a real issue for the industry post-Brexit, not least thanks to the cost of replacing an employee.

For example, the EEF reported that in 2017 13.2% of manufacturing employees changed job [6]. There are genuine concerns this could rise after Brexit, with fewer replacements available. Meanwhile Oxford Economics estimates that the total cost of replacing an employee – from recruitment to optimal productivity – as between £22,000 for small companies and £30,000 for employers with more than 50 employees [7].

If a manufacturer has 100 staff and an average level of employee churn (13 in a year), the cost of replacing them all to optimal efficiency would be a staggering £390,000. Every additional leaver adds a further £30,000 on average to this cost.

Anything businesses can do to create inviting and hospitable industrial workplaces will play a role in attracting and retaining the right workers and reducing the cost of replacements.

tp The Plastifoz production floor. Switching to LED – in this case the Urbis INDU range – increased light output, in turn improving employee safety. The right levels of luminosity and uniformity have allowed workers to concentrate better, again leading to higher performance and greater efficiency

LIGHTING AND PRODUCTIVITY

The EU’s ‘Lighting For People’ project (www.lightingforpeople.eu) has demonstrated how proper lighting in the workplace directly influences productivity. The project’s findings identify that lighting helps regulate workers’ circadian rhythms, in turn boosting mental performance and making them feel more alert and energetic. The better the light quality, the more pronounced this effect is [8].

The International Labour Organization (ILO) – a specialised agency of the United Nations – has gone one step further. In a study focused on factories in the garment industry, the agency has estimated that improved lighting levels can increase productivity by 10% and reduce errors in manufacturing by 30% [9].

This is a significant step-change in productivity that also helps improve worker wellbeing and profitability, in addition to saving a company significantly in energy costs. For British manufacturers, a 10% increase in productivity would be a game changer – significantly closing the gap on other EU countries.

INTEGRATION WITH CONTROL

A complete review of lighting requirements

in an industrial workplace, particularly one that replaces outdated fluorescent lighting with LED technology, is therefore a real opportunity to effect change.

LED lighting is uniquely directional, reducing light spill and concentrating illumination on the areas that need it. In a factory environment this has two major advantages. First, it reduces the cost associated with buying accessory devices that reflect or redirect light. Second, it is possible significantly to reduce the number of individual columns or luminaires required to deliver a safe and efficient working environment, so driving further capital and operational cost savings for business.

LED luminaires can also be easily integrated with control management systems and DALI protocol for increased flexibility in the management and maintenance of the network. This means that lighting levels can be set for different areas: focused on the factory floor to help drive better productivity and dimmed in worker break areas.

If machinery is not being used in a factory, lighting can be automatically switched off. Passive Infrared (PIR) sensors ensure that users have the light they need, where and when they need it without waste.

Another benefit of LED technology for www.theilp.org.uk

February 2019 Lighting Journal

Industrial lighting

factories and industrial sites is a reduced emission of heat. This is especially relevant where highly flammable substances are stored and used or where the build-up of combustible dust is a major issue. The reduced temperatures of LED luminaires in these environments reduce the risk of fire or explosion.

DESIGN IS THE DIFFERENCE

28

Light plays a fundamental role in how people feel and interact with a space. If an environment is too dark people feel unsafe; if a site is over-lit, people feel uncomfortable and hyper alert. In both instances, subtle changes in lighting design create big differences in how the space is used. The most effective lighting designs are a combination of emotion and technology.

For the industrial sector, harnessing the flexibility and control offered by LED technology can transform facilities into vibrant spaces that complement the architecture, culture and history of an area.

Take the McLaren Technology Centre in Woking, which is a great example of how it is possible to use LED floodlighting to support a company’s desire to be more sustainable.

In its case it has saved an estimated 13,000kWh of electricity per year through the use of LED in this way. The facility uses a combination of minimalist internal and external lighting to accentuate its curved, glass design, so providing staff with a vibrant, evenly-lit facility they can manoeuvre around with ease.

By factoring the lighting network into the site’s overall architectural design, McLaren has created a factory that both employees and visitors are excited to visit [10].

WIDER OPPORTUNITY

Some industrial organisations see the energy efficiency of LED lighting as the only motivation for adopting the technology.

This, we at Urbis would argue, is wrong.

Reducing energy consumption and supporting a move to make UK industry safer and more sustainable certainly plays an important role. But replacing legacy lighting for LED luminaires like-for-like is a missed wider opportunity.

With large swathes of Britain’s modern industrial infrastructure – including factories, industrial hubs and ports – built during the course of the last century, manufacturers can use a switch to LED as an opportunity to reassess their entire requirements inside and outside a facility.

This can include addressing how lighting can do a better job in terms of the health, morale and productivity of their workers and how lighting can better help them to meet energy consumption and sustainability targets without impacting on safety standards. Plus, of course, they get the benefit of modern, illuminated, controlled spaces of manufacturing excellence.

‘ENERGY EFFICIENCY AND PRODUCTIVITY’ Plastifoz is a Portuguese company that specialised in designing and developing products from plastic.

As part of its goal to meet growing market requirements and to expand its range of products, the firm decided to rebuild the production hall at its Figueira da Foz plant.

The aim of the refurbishment was to enable the company to consolidate its presence on the international market.

As part of this refurbishment, the company wanted a robust, energy-efficient lighting solution that would withstand the challenging ambient conditions of the site as well as provide optimal visual conditions for employees operating fine machinery. This, in turn, would increase visibility and productivity across the production line. www.theilp.org.uk

A total of 35 luminaires were installed from our INDU range. These highly efficient LED luminaires increased light output to help improve employee safety, whilst ensuring the right levels of luminosity and uniformity allowed workers to concentrate better, again leading to higher performance and greater efficiency.

As Jorge Silva, managing partner at Plastifoz, commented at the time: ‘The move to the new facility was crucial for Plastifoz. It was an opportunity to modernise the company by making it more efficient and increasing our production capacity. The LED lighting solution advocated by Schréder for the new industrial hall was an important tool to help us achieve our energy efficiency and productivity goals.’

SCOTTISH PREMIERSHIP Retrofitting LED has been at the heart of staggering energy savings of up to 97% at Volvo’s plant in Motherwell, Scotland. But achieving this – as well as winning a LUX award – has been about much more than just swapping out high-pressure sodium and metal halide lamps for LED

By Alan Robson and Liz Hudson

I

n 2015, the newly acquired Volvo facility in Motherwell, Scotland targeted its outdated lighting scheme as a key area for CO2 reduction, and called in Carbon Reduction Technology to assist. The move was in part driven by the facility’s managers needing to align themselves with their new owner’s strict environmental policies.

But the results would in time go much further than simple box-ticking, as the project would go on to achieve award-winning results, reducing power consumption by almost 3 million kWh per year and setting the bar impressively high for induswww.theilp.org.uk

trial energy efficient lighting.

The energy consumed by commercial buildings has doubled in the past 30 years, and is estimated currently to account for approximately one third of all energy consumed globally. Worryingly, from both a financial and environmental perspective, this consumption is set to grow by a further third over the next 20 years.

Moreover, when you consider that the majority of buildings that will exist in 2050 have already been built, it becomes only too clear why industries of all shapes and sizes desperately need energy and carbon reduction technology that can be viably retrofit-

ted into pre-existing infrastructure.

With the introduction of carbon credit fines and rapidly rising commercial energy tariffs, companies are under heavy financial and ethical pressure to reduce their energy expenditure and carbon emissions.

On top of this, obsolete lighting technology (sodium, mercury vapour and so on) accounts for a surprisingly large margin of emissions and financial expenditure in industrial sheds, particularly for facilities which operate around the clock.

THE MOTIVATING FACTOR

This background serves to illustrate just

31 some of the motivation and background drivers behind Volvo’s focus on energy efficiency, and energy efficient lighting, in Motherwell.

The site had previously belonged to the Terex Trucks brand, a robust articulated and rigid dump truck manufacturer, before being purchased by Volvo Construction Equipment in 2014.

Renamed Volvo CE Motherwell, the facility now consists of two large sheds and a test track, a parts distribution operation, office and staff areas, plus extensive bays for the complete-from-scratch development of extreme haulage vehicles.

The facility covers all aspects of automotive production, including plasma cutting, gas burning, press bending, fabrication welding, machining, shot blasting, final paint process, full assembly and testing.

Whilst the Motherwell facility had always focused on meeting compliance targets, the acquisition by Volvo Construction Equipment brought in new core values within the business, values in line with its new owner’s own mission and remit.

These were, namely, excellence within safety, quality and environment. At a practical level, the facility set itself a new goal: become carbon neutral.

As Paul Hudson, operations director at Volvo, Motherwell, explains: ‘Environmental focus was new to the business,’

adding that, ‘in terms of our improved performance, this was the biggest challenge that the business faced.’

To meet this challenge, Volvo turned to us at Carbon Reduction Technology (CRT).

We, as many within the industry will undoubtedly know, design, manufacture and supply high efficiency LED lighting. We are well established within the public sector and began supplying to the industrial

sector several years ago, working primarily with automotive specialists such as Grupo Antolin, Gestamp Tallent and Renault.

Unusually (but refreshingly) when CRT first began work with Volvo Motherwell in 2015 the company already had a comprehensive idea of what it needed. The lights had been singled out as a key area for upgrade, after careful analysis had identified the mammoth energy usage (and bill)

attached to running its pre-existing high-pressure sodium and metal halide lanterns every month.

Additionally, the Volvo team wanted a control and monitoring system in place so that energy usage data could be utilised for decision making in four key areas: capital investment; process improvement; building and machinery utilisation; and driving KPIs. At the time, CRT had no bolt-on option for smart networking, and so we reached out to the Carbon Trust, who introduced us to the enModus smart building solution. enModus uses existing infrastructure and power cables to send and receive signals.

This makes the system far more reliable and viable over a large area than, we believe, any other existing control technology.

The Volvo team approved the addition of enModus to the venture and an ambitious project got the official go-ahead to begin.

THREE DRIVERS OF EFFICIENCY

It is relatively easy to do a straight swap between sodium, mercury vapour or halide lamps and LED luminaires and it will result in a carbon and energy saving.

However, this approach tends to leave a large margin of wasted potential, which www.theilp.org.uk

translates to more carbon emissions than necessary and a smaller volume of financial savings. It is also vital of course that a luminaireâ&#x20AC;&#x2122;s components can withstand the stresses associated with round-theclock operation.

Volvo Motherwell therefore squeezed out every ounce of efficiency in three ways.

1) Like-for-not-like. When we surveyed the distribution area, we quickly concluded that a like-for-like replacement would result in serious overkill and excessive waste. The original lamps produced an average of 170 lux at floor level with a murky orange colour temperature which resulted in a lot of shadow. By comparison, the CRT high bay luminaire, the HBX, pumped out much greater light and higher lux levels, offering far better light distribution and uniformity following the application of environment specific optics. Our engineers realised that in many areas we could replace as many as eight original lamps with as few as three HBX, and still achieve an average 450 lux of even illumination at ground level â&#x20AC;&#x201C; a lighting performance improvement of more than 250%. In a like-for-like comparison, the energy difference between the old and new lights in the distribution building came to an average

46% reduction (average of 275 watts to average of 148 watts). But for many assets a 100% reduction was achieved, as they were eliminated completely from the lighting scheme.

The total power reduction for both industrial sheds, before controls and sensors are added, comes to 2.2 million kWh (66%) per year.

2) Daylight harvesting. Whilst most of the facility was well enclosed, there were plenty of areas where a good amount of natural light could still enter through skylights and windows.

The HBX installed in these areas were outfitted with ambient light sensors that measure the available light and only emit enough artificial light to bridge the gap between existing light levels and the required light level.

The sensors continuously manage this process, adjusting the output (and energy input) accordingly.

3) Passive infrared sensor (PIR) occupancy monitoring. In areas that donâ&#x20AC;&#x2122;t see continuous human activity, such as the distribution centre and warehouse, PIRbased dimming was installed to cut down wasted energy and light.

When dormant, the luminaires emit a low-level safety light and, when the system senses movement below, it subtly raises

February 2019 Lighting Journal

the lux output to operational levels.

In this way, a well-planned lighting scheme has much more to offer than when compared with a straight swap to basic LED.

CONTROL AND MONITORING

The addition of a control system can be an attractive option for many commercial operations, as there is usually plenty of excess that can be trimmed from any system that requires continuous electricity to run, regardless of how efficiently assets use energy.

Additionally, a smart system can provide valuable monitoring services, such as producing mandatory energy usage reports, energy scheduling and identification of redundant energy usage.

To that end, the new control system installed at Volvo Motherwell plays a key role in maintaining safety standards. The system can monitor and regularly check the operating status of emergency lights, as well as sending alerts if lighting conditions become physically or legally unsafe.

As already touched upon, the enModus Wattwave system uses pre-existing powerlines to send and receive signals, so making it more reliable over large distances than most other control technologies.

Each luminaire is pre-fitted with a node that links it to the system. Volvo was also able to begin attaching its shop-floor machines to the control system, expanding its control and monitoring capabilities beyond the lighting network.

p An example of an SLX2 exterior wall-mounted luminaire, one of the new lighting additions to the site, which runs shifts around the clock

JOB DONE?

Not many people believe us when we tell them that Volvo Motherwell’s distribution centre and warehouse has achieved total energy savings of between 92% and 97% (depending on the work area).

However, those figures have been independently verified by the Carbon Trust.

What this shows very clearly is that, when done well, the results of an upgrade to LED can be utterly mind-blowing.

But, even with these headline figures,

there are still a few outstanding questions that will be of interest to lighting professionals.

• What are the real financial savings and re-contribution to the facility’s bottom line? Volvo Motherwell’s annual sitewide savings are currently set to exceed £350,000 per year. Over ten years of operation, savings are expected to exceed £5m, accounting for energy inflation.

• How long will Volvo be paying for the

project, before it feels the financial benefit? Projects of this nature tend to have an extremely rapid payback, as the month-on-month saving is so extreme.

Volvo Motherwell expects to achieve full payback on each stage of its HBX and control system installation through energy savings within 18 months.

There are also plenty of incentives available for projects such as this. For example, Volvo Motherwell was able to take full advantage of tax relief for the upgrade through the CRC Energy Efficiency Scheme. It is also possible to acquire interest-free funding for projects of this nature, through organisations such as the Carbon Trust. When paired with the fast return on investment, we’d argue options like this can often open up a wealth of possibilities for British manufacturers and industrial shed owners.

• What is the annual site-wide power saving in kWh? Volvo Motherwell’s annual site-wide savings are currently set to exceed £350,000 per year. Over ten years of operation, savings are expected to exceed £5m, accounting for energy inflation.

• How much CO2 is being saved? The reduction in Volvo’s carbon footprint is dramatic. Per year, the Motherwell facility will save just over 1,332 tonnes of CO2. Over ten years, that’s enough CO2 to offset the emissions produced by average passenger vehicles over 32.5 million road miles.

NEXT STEPS

The building retrofit in Motherwell attracted a lot of attention during its execution. In 2016 the project became the focus of a Carbon Trust incubator case study and in late 2018 the project won the Industrial & Transport Lighting Project of the Year category at the Lux Awards.

At time of writing (in November), the full project completion was due by the end of December, including the industrial high bay areas plus offices and staff facilities. By the time of publication, this should therefore now have been completed.

Volvo Motherwell plans to continue to develop its asset monitoring systems and investigate the viability of voltage optimisation for its shop-floor machinery. The Motherwell team is ready to move on to the next stage in its mission to become completely carbon neutral.

As industrial building retrofit becomes more and more popular (and necessary), we at CRT have also moved now into the early stages of retrofit projects with a number of additional Volvo facilities, in addition to maintaining a healthy portfolio of other industrial brands.

he Hong Kong-Zhuhai-Macao Bridge, believed to the world’s longest sea bridge, formally opened for traffic in October.

The bridge-tunnel system consists of a series of three cable-stayed bridges, one undersea tunnel and has even led to the creation of two artificial islands.

It spans the China’s Pearl River Delta and connects the islands of Hong Kong and Macau with the city of Zhuhai on the Chinese mainland.

Construction began a decade ago, in 2009, with the 115.9bn Yuan (€14.7bn, £13bn) project proving to be highly demanding, not least because of the frequent typhoons that u Six thousand Thorn GTLED Entry and GT58 luminaires with DALI drivers have been used to illuminate the 1km tunnel, and were chosen for their performance, uniformity and long life

barrel through the region, airport height restrictions, the complexities of creating the two islands, the project’s high environmental standards and the passage of shipping to contend with.

This led to the project suffering delays and budget over-runs, including the slippage of its original opening date of October 2016.

Nevertheless, with three lanes in each direction, the 30km bridge – part of a crossing totalling 42km – should dramatically reduce driving time from Hong Kong to Zhuhai and Macau from around fourand-a-half hours to just 40 minutes.

The project is part of a wider drive by the Chinese government to develop the

For the lighting, Thorn won two of the three lighting contracts associated with the bridge – to illuminate the two artificial islands at the east and west of the crossing, and the tunnel that leads to the bridge from Hong Kong.

Thorn duly provided 120 Champion Pro LED 132 high-power floodlights, mounted on 12 high masts. The fittings were chosen for their high efficacy of 115lm/W, long lifetime of 70,000 hours (L80), IP66 rating for ingress protection, and success in passing a 1,000hour salt-spray test, making them perfect to withstand the tough environment.

The fittings use 600W of power, compared to 1,000W for conventional alternatives.

For the tunnel lighting contract, 6,000 of Thorn’s GTLED Entry and GT58 luminaires with DALI drivers has been used to illuminate the 1km tunnel. These dedicated tunnel luminaires provide high uniformity and long life.

‘We previously completed a successful renovation project in Hong Kong’s Shing Mun Tunnels with the main contractor, and have thus gained high recognition for our professional lighting solutions and competence,’ explains Simon Chan, general manager for Zumtobel in Taiwan.

‘The lux calculation of our tunnel lighting solution complies perfectly with the tender specification, which stood out from the competitors despite the complicated and strict requirements in the electrical and mechanical installations,’ he adds.

t goes without saying that many businesses, public bodies and households already benefit from lower bills by implementing energy saving projects.

Individually these actions are often small, but together they represent a huge – and essential – contributor to the de-carbonisation of our energy system.

Recent research by the Energy Efficiency Financial Institutions Group has calculated the size of this opportunity at a trillion euros across the EU alone [1]. At a commercial level, because most projects have a positive return-on-investment – indeed, they will often save more than they cost over the course of just a few years – organisations are often keen to implement them because both the financial return and the environmental kudos make sense, plus it is often just perceived as being the ‘right’ thing to do. There is also a growing interest among investors (such as banks or infrastructure funds) to put their money into energy efficiency.

But, even though energy efficiency projects are now increasingly mainstream, there are a couple of problems. For starters, no two energy saving projects are alike. All share the aim of reducing energy expenditure, but their routes to achieving this are likely to be very different. A project to, for example, tweak the controls in a commercial building to reduce consumption differs hugely from the installation of solar panels on the roof of a hospital.

The result is that organisations looking to carry out these projects may spend excessive time and money understanding each investment opportunity – costs that detract from the overall investment case.

This can make sourcing and agreeing www.theilp.org.uk

suitable finance difficult, whether it is coming from internal funds or an external lender. This, in turn, can mean that, even if projects stack up financially, they may end up being reduced in scale or, even worse, aborted altogether.

THE INVESTOR CONFIDENCE PROJECT (ICP)

What, I hear you ask, has any of this to do with street lighting? The answer is – the Investor Confidence Project (ICP), which

we believe can offer part of the answer to help lighting professionals, especially budget holders in local or municipal authorities, square this financial circle.

What is the ICP? The ICP is an international framework, originally initiated in the United States in 2011 with support from the Environmental Defense Fund. In 2015, ICP was brought to Europe, thanks to a grant from the European Commiss i o n ’s Ho r i z o n 2 0 2 0 R e s e a r c h programme.

February 2019 Lighting Journal

ICP’s objective is to increase the flow of investment into energy efficiency projects – whether street lighting or other – by standardising how projects are developed, documented and measured, and ensuring they reach high standards of technical excellence and transparency.

It awards an ‘Investor-Ready Energy Efficiency’ (IREE) trademarked certification to projects that are certified as meeting the IREE standard. This ensures that projects are developed using best practices, the right professionals and thirdparty validation, and can visibly be shown to have done so.

At the core of the ICP framework are a number of ICP protocols. These assemble best practice and existing technical standards for the whole lifecycle of energy efficiency projects. They act as an essential resource for anyone trying to develop such an energy efficiency project.

Using the ICP system means getting access to: • A standardised, repeatable project process, broken down into key stages and giving clear guidance on the processes and documentation expected at each stage • A best practice approach to predicting project savings and subsequently realising those savings. Following an ICP protocol will deliver a well-planned and robust project where the energy savings are clear • Projects that have followed this best practice approach and have undergone an independent quality assurance review are awarded the IREE certification The nub of this is that, first, for projects that are using external funding, this reduces the cost of due diligence exercises, because this is only carried out once for each project, thus making the finance cheaper. Ultimately, this approach will therefore help more investment in energy efficiency to take place, as projects become standardised and investors can rely on their quality. In future, the goal is that this will allow project developers to choose from a range of potential funders, whereas at the moment this choice is very limited.

But equally importantly, second, for projects that use internal funding (for example within a local authority or private company) using an ICP protocol can give internal budget holders confidence in the quality of the project and its outcomes.

And for many project developers in the sector who are largely following best

practice already, the additional effort to comply should be minimal.

ICP AND STREET LIGHTING

Having focused initially on establishing itself within the buildings sector, ICP Europe has just completed a protocol specifically designed for street lighting projects as part of a new programme focusing on industry and infrastructure, funded by the European Commission.

Integrating these very different project types into a unified system will help to attract investors. Moreover, it offers project sponsors (who, let’s not forget, are often working within resource-constrained public bodies) an easy route for developing a project proposal in line with industry best practice. In turn, the best project developers and contractors can differentiate themselves by joining the ICP ‘Project Developer’ networks.

ICP also operates an Investor Network comprising around 30 investors keen to deploy capital in energy efficiency, some of whom are able to offer beneficial terms to IREE-certified projects.

According to research from the Climate Group, there are more than 300 million streetlights globally, growing to 352 million by 2025 as cities expand. Smart LED systems will cumulatively represent a

US$63.5bn market opportunity. In the UK, an annual energy cost saving of £200m is estimated to be available by switching to LED street lighting, and the investment could be paid off in ten years [2].

For cash-strapped public bodies, it is well-recognised within the industry that attractive energy savings of 50-70% are achievable by upgrading traditional street lighting to LEDs. Retrofit projects, too, can be a good opportunity to introduce

ensure that investment in LED street lighting delivers in practice. In the process, and with the digitalisation of lighting continuing apace, this arguably has the potential to open up street lighting projects to a bigger investor market of technology providers and other contractors with solutions to offer.

CONCLUSION

new features such as CMS, which can boost savings further.

Lighting columns, of course, are also a key part of the future-facing vision for urban infrastructure, whether it be as an ambitious platform for new smart city features to enhance the lives of citizens or, more prosaically, simply via Wi Fi ‘hotspots’ or air quality sensors. Ultimately, in the cash-strapped local authority climate, it is external finance that can unlock and allow a public sector body to experience the benefits of LED street lighting while paying for the upgrade from the energy savings over time.

By codifying best practice in accurately calculating and delivering energy savings, the ICP street lighting protocol can help to www.theilp.org.uk

The ICP street lighting protocol is ready and waiting for lighting professionals and local authorities to discover, and can be accessed free online [3]. It provides a valuable resource for specifying and developing street lighting projects from the earliest stages through to completion and performance monitoring, bringing together best practice standards and methods from around Europe.

Basing the business case on the ICP protocol and reaching the IREE standard can make a project attractive more to investors, whether they are sitting within the same organisation or bringing funds in from outside for example via, as already highlighted, the ICP Investor Network.

For project developers and contractors, gaining IREE certification and becoming an ICP project developer is a way to demonstrate the quality of your street lighting solutions in a competitive market. The ICP system is intended to encourage larger scale, more ambitious projects by facilitating access to external investment.

Finally – and perhaps most importantly – ICP Europe are looking for pilot projects to certify as IREE under the new protocol.

Funding is available until September

2019 for technical support to help reach certification, so projects benefit from a free quality assurance service. In other words, if you’re interested, don’t delay!

TALK The expertise and authority of ILP members was once again firmly on display at November’s LuxLive exhibition and show

By Nic Paton

www.theilp.org.uk

W

ith eight conference tracks to choose from over two days, November’s LuxLive show and exhibition was, as ever, full of fascinating CPD and presentations, with ILP members once again very much to the fore.

While inevitably what follows is just a snapshot, what were some of the highlights?

Matthew Webster of British Land argued that, for him, ‘the jury’s still out’ on the benefits of circadian lighting within the workplace, especially whether it makes sense for indoor lighting to get brighter as the daylight fades, so as to keep people alert.

As he said: ‘It does need more investigation on how it’s supposed to benefit us in the workplace.’

Matt Love of Tesco highlighted how lighting has become a much more integral part of the design process within retail, and is even becoming part of the conversation from the early stages.

‘These days, lighting is integrated into the whole concept from day one,’ he argued, with the flexibility of LED meaning that it was ‘now easier and much more interesting for designers to get to grips with’.

REGENERATING HULL

Mark Cooper, senior consultant – smart cities and products of CIMCON Lighting, looked at the challenges posed by increasing demands to use lighting columns as urban conduits for gathering and analysing digital data.

The role of light and lighting in the regeneration of Hull, including its instrumental part in the city’s three-year stint as the UK’s City of Culture up to 2020, was examined

by Dan Lister, associate at Arup.

Some one-and-a-half miles of the city’s central public realm, civic buildings and historic monuments have been lit up to boost its night-time economy, reduce the fear of crime and curb anti-social behaviour.

Mark Sutton Vane, of Sutton Vane Association, spoke about ‘how to light the world’s largest museum’, or his practice’s role in illuminating the newly-opened Sheikh Abdullah Al-Salem Cultural Centre in Kuwait, which at 22,000sq m is one of the largest cultural projects in the world.

Sticking with immense projects, Jonathan Rush, partner at Hoare Lea, spoke about his team’s work in illuminating the New Istanbul Airport, which is set to be the world’s largest when fully completed.

As Jonathan explained, from beginning work in November 2014 to handing over to

February 2019 Lighting Journal

local architects in December 2016, more than 260 drawings were completed, 60 documents and more than 360 calculations. ‘We lost count on 50,000 downlights, and that does not include the kilometres and kilometres of linear lighting embedded in the space.’

The lighting scheme has been heavily influenced by the symbols and iconography of Istanbul’s mosques – including a repeating motif of gold oculus forms – as well as the creative use of sunlight and daylight design.

TACKLING LIGHT POLLUTION

Also from Hoare Lea, partner Dominic Meyrick gave an impassioned presentation on the need for lighting professionals to do more to tackle light spill, trespass and pollution at night.

As he put it: ‘Stop looking at street lighting recommendations and saying, “it is all fine”, because it’s not. You know it and I know it. For goodness sake, if you care about the planet, stop being selfish. It is our planet. Your kids are going to live with the decisions that you make. It is, I get it, an absolutely overwhelming issue but it has to start with us.’

Visitors to LuxLive heard Peter Earle, business development manager at Philips OEM Technology at Signify, talk about the company’s new TrustSight Gen3 emergency lighting portfolio. Peter also spoke as part of a panel discussion on the role of the ‘Internet of Things’; (IoT) within emergency lighting.

This discussion will be outlined in

more detail in next month’s Lighting Journal but, in a nutshell, the panel argued that, while IoT has the potential to transform how emergency lighting is managed, tested and maintained, this must not come at the expense of building owners becoming complacent or overly-reliant on potentially vulnerable internet connectivity.

The show also had a conference track called ‘Property Technology Live’, devoted to all-things digital in the context of the built environment. This was marked by the visibility of software and technology professionals, rather than their lighting counterparts, perhaps a sign of things to come within the market.

Finally, the ILP, as usual, had its own busy stand at LuxLive and on the Thursday morning held a membership development CPD conference, which proved popular with visitors.

This included a presentation from Professor Peter Raynham, professor of the lit environment at The Bartlett at UCL, on the role of membership assessors, while Nathan Poundall, engineer at Lincolnshire County Council and a member of the ILP’s Membership Committee, explained how graduates can upgrade to full ILP membership.

Guy Harding, Chairman of the ILP’s Membership Committee, was also on hand to explode a number of common myths about upgrading to MILP membership, such as the perception that you cannot do so without a higher education qualification, which is not the case.

Light on the past

THE BLACK OUT 44

Despite the best attempts by lighting engineers to persuade ministers otherwise, the government’s advice on the announcement of war was immediately to turn off all the lights as part of the ‘black out’.

But the clamour for an alternative solution to newly-darkened, potentially dangerous and threatening streets became louder

By Simon Cornwell

T

he outbreak of the Second World War had immediate, almost farcical, repercussions for the Association of Public Lighting Engineers (APLE).

Many of its members were in Glasgow for the association’s sixteenth annual conference when war was declared on the 3rd September 1939.

As manufacturers were busily attempting to install showcase installations along the city’s streets, the local Glasgow lighting engineers were desperately trying to turn everything off, and the intended audience were hurriedly packing their bags and making their way home. The association did allow itself one frisson of excitement; no lesser an authority than the BBC were contacted, and broadcast to the nation that the September APLE conference had been postponed.

Despite the attempts by some public lighting engineers to keep the lights on, the diktat from central government was to turn all the street lighting off. The Air Raid Precautions Department (ARP) had issued a memorandum in 1939 outlining the requirements by local authorities on the declaration of war, and its opening line was unambiguously clear: ‘In time of war, street lamps would be extinguished, and vehicle lighting would be restricted.’

It gave clear directions for the screening of traffic signals, the alteration of lighting for warning and direction signs, and the provision of obstruction lighting.

This document was also responsible for the resultant Pathé footage of cheery householders and resolute workmen whitewashing columns and kerbs. In a section entitled ‘White paint’, instructions were given for the painting of kerbs and the now redundant street lighting columns, in other words horizontal bands 6” wide and 6” apart, from ground level to a height of 3ft. An enterprising lighting engineer in Bolton even suggested using the old columns as direction indicators to point to air raid shelters, first-aid posts and fire alarms.

DEVICES FOR OBSCURING AND DIMINISHING LIGHT

Manufacturers wasted no time in offering masks, louvres and other obscuring and/or diminishing devices for lighting equipment, as stipulated in various ARP publications. Among their new product lines were also direction signs and lighting for the new shelters, which were being hastily constructed.

British Thompson Houston, for example, was extremely quick off the mark, and

p Issued in 1939 by the Air Raid Precautions Department, the Memorandum On Aids To The Movement Of Traffic To Be Installed In Roads And Streets In The Absence Of Street Lighting dealt with the practicalities of losing street lighting when war was declared

its cover advert for the September issue of Public Lighting offered no street lighting at all, but a range of new lamps, adapters, shades and shelter signs, stamped with the approval of the ARP. Other manufacturers were offering novel and ingenious solutions for dealing with the practicalities of the ‘black out’, attempting to mitigate against its more onerous requirements.

Philips stood out with its practical solutions to several black out problems. One was its ARP black-sprayed lamp, aimed at householders, which provided a tiny amount of illumination via a small transparent region at the top of its glass envelope.

Then there was its ‘Philora Complementary Colour Light Obscuration System’, which used complementary colours to provide black out from the windows of factories, hospitals and industrial premises.

A special blue varnish was applied to all the windows, whilst existing lighting was either fitted with orange-sprayed tungsten lamps or replaced with Philip’s own Philora low-pressure sodium lighting.

The blue varnish blocked the emission of the monochromatic orange light from windows but allowed daylight in. The result was blue-tinged natural lighting during the day, and orange light during

t British Thompson Houston anticipated the start of hostilities and was one of the first lighting firms to offer products specified by the ARP memorandum

the night – but with nothing visible from outside the building.

Yet the black out wasn’t seen in all quarters as strictly necessary. The consensus was that, for the morale of the nation, some form of street lighting should be permissible soon. Hopes were based on a Home Office circular from February the previous year that said: ‘If any relaxation were found to be necessary, it would not go beyond permitting between raids a certain amount of modified street lighting, carefully screened and capable of being instantly extinguished on receipt of an air raid warning in the main thoroughfares of the largest towns, and then probably only in the less exposed parts of the country.’

The paramount need was one of safety, and it was felt that switching off all the lights was in opposition to this.

Further hope was given by home secretary Sir John Anderson, who stated he was not satisfied that advantage lay on the side of leaving the lights to be extinguished when an air raid warning was received.

However, he announced he was ignorant of the system by which streets, however brilliantly lit, could be plunged into perfect darkness by means of central switches, but was looking into the matter.

DEBATE OVER VALUE OF CENTRAL CONTROL

t Philip’s ARP black-sprayed ARP lamp aimed for the domestic market and was clearly a one-for-one replacement for standard GLS lamps.

Its localised, highintensity illumination was emphasised as the man evidently didn’t need his spectacles

Anderson didn’t need to look far. Manufacturers who specialised in central control systems, and who had been extolling the merits of their products for years, increased the clamour and range of their equipment as the threat of war came nearer.

The Automatic Telephone and Electrical Company Limited heavily pushed its ‘Rythmatic Control’ system, expanding its function from street lighting to sirens, wardens, police, firemen and first aid. It even produced a ‘Portable Emergency Alarm Set’, a repackaged version of the same relay equipment used in streetlights, which could be plugged into the mains, and tuned to alarm at a certain frequency.

A demonstration of Rythmatic’s abilities was given along St Helier’s Avenue, Morden on the 28th July. St Helier’s Avenue was Morden’s showcase thoroughfare, where new medium-pressure

t Companies such as the Automatic Telephone And Electric Company Limited were quick to promote their high-frequency signalling systems in time of war.

‘Rythmatic Control’ could be used to control street lighting and sirens, and alert wardens, police, firemen and first aid. How long before the bombs would fall?

mercury lanterns fitted with magnetic arc deflectors were showcased in an inauguration ceremony just the previous year.

At an inauguration ceremony, where the needs for national defence were clearly spelt out, the chairman of the Electricity Commission pressed the ‘off’ switch: the lamps in St Helier’s Avenue were immediately extinguished and units of the ARP and first aid services were alerted, who arrived from neighbouring Mitcham and www.theilp.org.uk

Beddington in full ‘fighting kit’ just minutes later. Unfortunately, Sir John Anderson wasn’t in attendance!

REDUCTION OF LIGHT OUTPUT

Another option being actively explored was a reduction in the light output of existing street lighting lanterns. Research had started in exploring the possibility of producing a light source which could allow limited traffic movement by

offering a modicum of illumination but was invisible from the air.

Lighting engineer P J Robinson in Liverpool was conducting experiments along this line, using a new type of (unspecified) electric lamp. But, most importantly, he had the ear of the Home Office, who were involved with his scheme.

The feeling among some during these first months of the war was that the black out was an over-reaction and completely unnecessary. Whether central control or some form of modified lantern with greatly reduced illumination was the solution was actively being ascertained.

But it was left to one anonymous correspondent to The London Daily Express to sum up the dark streets and black out. ‘I feel sure that in the future people will not be so ready to grumble about their rates and taxes demands. Never until the present black out have I appreciated so much the social service of street lighting.’

Aluminium Rotating Mast Arms enable safe operations Maintaining traffic signals on busy, multi lane carriageways is a costly, disruptive and potentially dangerous operation.

The highway is a very unforgiving workplace and any new solutions that can improve the safety of operatives whilst minimizing disruption to the travelling public must be welcomed.

A rotating mast arm can overcome all these issues. Manufactured from Aluminium it is lighter in construction than traditional solutions and is therefore quicker and easier to install and benefits from a smaller foundation size than existing options. Operation of the rotating mechanism is a one-man job with an internal winch being located in a separate door compartment at ground level.
