hat should lighting professionals make of the preliminary conclusions of the ILP’s National Lighting Survey, carried out with Carbon Reduction Technology? In particular, how worried should the profession – and ILP members – be about the finding that 13% of local authorities reported now having no lighting specialist on their staff, and just a fifth (22%) employed more than three lighting specialists? In the immortal words of one of my favourite authors, Douglas Adams, in The Hitchhiker’s Guide to the Galaxy, I personally think the most appropriate response should be ‘don’t panic’ (in large, friendly letters). Why? Clearly, these results are a worry. But I’d venture to suggest they are more evidence of the wider impact of nearly a decade of austerity and cost-cutting within local government than any specific ‘problem’ with lighting. Many local authorities have felt the pinch in many areas, and lighting departments have been no exception. Moreover, the structural changes we’ve seen within the industry in recent years, notably increased casualisation, outsourcing and contracting-out of roles and services, means that simply counting those directly employed may not in itself tell the whole story. Within this, there is (to me at least) the intriguing finding that there is an active minority of ILP members within local authorities who are not classed (or do not class themselves) as lighting specialists. Nevertheless, there is much here for the ILP to digest, especially for Highways VP (and soon to be VP Local Authority) Ian Jones and his team. Indeed, as Ian makes clear in our article, the hope is this research will be a springboard to a second, more in-depth survey. Either way, I am sure it will be a central topic of conversation when we gather later this month at the Professional Lighting Summit in Newcastle. On that, I think the speaker line-up, the workshops and the roll-call of exhibitors who will be at the Summit between 12-13 June is looking especially strong this year, and well done to the ILP organising team. While I know carving out the time and budget to get out of the office to attend CPD can be challenging, please if you can do register and come and join us in Newcastle. It really is worth doing. You can find all the details online at www.theilp.org.uk/summit Whether this helps with the argument or not I don’t know, but I’ll be there over both days and, as always, on the hunt for people up for putting themselves forwards to write in these pages. So, please, don’t be shy, do come and find me. I look forward to seeing you in Newcastle.

STATE OF THE NATION? What is the appetite among local authorities to hire and retain lighting professionals? How popular are dimming and part-night lighting regimes? How popular is retrofitting versus replacement? These and other pressing industry questions have been tackled by the ILP’s national lighting survey, in association with Carbon Reduction Technology. And the preliminary findings are in By Liz Hudson

B

etween September last year and March this year, the Institution of Lighting Professionals (represented by VP Highways Ian Jones) and Carbon Reduction Technology have been working together to conduct a nationwide study of local authority lighting, with an emphasis on LED. The study aimed to tackle some of the key questions and subjects around local authority street lighting, including measuring progression towards total conversion to LED, current savings in both energy and carbon, retrofit versus replacement trends and the ongoing role of locally employed street lighting specialists. With the results now in, this www.theilp.org.uk

article intends to give a brief, preliminary overview of the key findings and what they potentially say about the changing nature of our industry. The survey was offered to all metropolitan district, county, unitary and London borough councils in the UK, including England, Scotland, Wales and Northern Ireland. It covered conventional streetlights and reproduction or heritage lanterns; it did not cover motorway lighting. The full report will be released to coincide with the ILP Professional Lighting Summit later this month, bringing the project full circle from inception to publication just inside of a year. Those who participated in the survey were due to

LIGHTING SPECIALISTS

In the late 1980s, 98% of ILP membership was made up of lighting engineers, a figure that has dropped below 20% in recent years. While, undoubtedly, a surge in commercial memberships will have affected this ratio, we wanted within the survey to look a little more closely at the population of lighting specialists employed within local government – particularly given the increasing outsourcing of local authority lighting to external providers. During the design phase of the study, we decided therefore to focus on ‘lighting specialists’ rather than engineers, as a lighting team is often made up of a more diverse selection of professionals. The results indicate that there are just above 600 lighting specialists employed within local government in the UK. Approximately 13% of local authorities reported having no lighting specialists on their staff, and only 22% of authorities employed more than three lighting specialists. We also compared the average number of lighting specialists per region against the average

number of operational streetlights. This is shown in figure 1 above. We asked each participant how many members held ILP membership, and therefore had access to its resources, support and training. The national average for this was 52%. However, we were surprised to discover that at least 9% of local authorities had active memberships for one or more employees who were not classed as lighting specialists. This included 40% of the authorities who did not directly employ a lighting specialist. This could well be something for the ILP to drill down into in any future surveys. While contractors do an admirable job, locally employed lighting specialists

bring many advantages to the table. It will be important for the industry, using these figures as a benchmark, to determine if employment opportunities for lighting engineers and specialists within local government are stable, growing or dwindling. As Ian Jones, VP Highways (soon to become VP Local Authority under the proposed changes to our structure), comments: ‘It is a concern that local authorities now represent a far smaller proportion of our membership than in the 1980s and 1990s. ‘As our survey highlights, more than a tenth of local authorities now report that they have no lighting specialists at all on their staff and only a fifth employ more

8 than three lighting specialists. ‘This is, of course, a reflection of the wider financial and operational pressures local authorities are all under, as well as the changing nature of our industry and how it is structured and delivered. But it is nevertheless something that all of us, both inside and outside the ILP, need to reflect on and try to address in the future. ‘What is more positive is the finding that more than half of those lighting teams within local authorities do have ILP members within them and that there is a significant minority of non-lighting specialists who are also ILP members. This, I feel, shows the continuing reach of the ILP and the influence and authority we retain as an organisation. ‘This is a figure my team and I can work on to improve over the coming months. Indeed, we are hoping to carry out a secondary survey in the future to further understand how the industry is changing, particularly in local authorities across the UK. When this happens, I urge all local councils to get involved and ensure their voices are heard,’ Ian adds.

DIMMING/PART-NIGHT LIGHTING

As well as employment within the industry, the survey looked at the trend of www.theilp.org.uk

dimming and part-night regimes. Dimming and part-night regimes of course have the potential to contribute significantly to energy saving and carbon reduction initiatives. However, part-night in particular has received some backlash at the local level. Our study therefore set out to discover how widely used dimming and part-night regimes are and what sort of returns these schemes have produced. Our findings suggest that approximately 52% of local authorities have at least some dimming schedules in place, and only 8% of those authorities save less than 10,000

kWh per year via the scheme. The average saving on dimming is 2.1 million kWh per year, per participating authority. The authorities with the largest initiatives report savings in excess of 12 to 14 million kWh per year. Part-night regimes were slightly less prevalent, with only 19% of authorities reporting any activity in this area. The largest part-night scheme reported was saving approximately 938,000 kWh per year. According to the gathered data, only 14% of local authorities ran both

dimming and part-night initiatives concurrently. The findings suggested that current national savings were in the region of 179,000 megawatts for dimming regimes and 12,400 megawatts for partnight, annually. This equates to a combined saving of 57,000 tonnes of CO2 per year.

RETROFIT VERSUS REPLACE

Another key question addressed by the survey was retrofit versus replace. It is well-recognised that one of the key planning decisions for any local authority in the current financial climate is the option of whether to retrofit rather than replace. Whilst retrofitting is not always a viable option, when it is possible it can offer project cost savings and a significant reduction in supply chain carbon footprint and waste disposal. We therefore asked participants what percentage of their upgraded streetlights and heritage lanterns had been retrofitted versus replaced. The findings are shown in figure 2 on the previous page. As you can see, there was a much higher propensity towards retrofitting heritage lanterns over conventional streetlights. Nationally, the average for heritage lanterns upgraded via retrofit is 28%. Our study also suggested that as many as 17% of UK local authorities retrofitted between 90% and 100% of their upgraded heritage lanterns. By comparison, just 13% of conventional streetlights were retrofitted and only 4% of local authorities had retrofitted more than 90% of this far larger www.theilp.org.uk

category of lantern. By our estimate, conventional streetlights outnumber heritage lanterns by 48:1. This can be seen in figure 3

ENERGY AND CARBON SAVINGS

One of the major motivating factors behind our study was the opportunity to generate quantitative evidence on the contribution of local authority lighting teams to national emissions reduction. By installing more efficient lighting, councils are not only directly reducing their carbon footprint but are reducing the load on the national grid, which in the future could help the UK to fully transition to a clean energy infrastructure. We split the luminaires we surveyed into categories in order to increase accuracy, as post height usually has a direct impact on operational wattage. As figure 4 overleaf shows, these were our findings. We also asked how many luminaires each authority owned from each category and how many had been converted to LED. Furthermore, we asked for conversion estimates for March 2019 and December 2020. The results can be seen in figure 5, also on the next page.

CONVENTIONAL LANTERNS CONVERTED TO LED (NATIONAL AVERAGE)

LED CONVERSION

As of March 2019, our survey results indicated that 51% of all local government-controlled streetlights had already been converted to LED. Based on estimates from the participating authorities, we expect this to rise to 66% by December 2020. The study also suggested that 40% of all remaining unconverted streetlights had already been assigned to a supplier, as shown in figures 6 and 7.

We estimate approximately 10% of local authorities have now fully converted to LED and, of the remainder, 20% have fewer than 2,000 luminaires left to upgrade. To conclude therefore, based on the study data we estimate the full potential of a total national LED upgrade could produce a saving of up to 1,723,502 megawatts of energy and 514,982 tonnes of CO2 per year. While we expect the UK to have made considerable progress towards a total conversion to LED, it is also important to remember that a number of authorities will be seeing out the operational lifetime of alternative technologies or replacement contracts put in place before LED became the national standard before they are able to upgrade.

FIVE REASONS WHY YOU SHOULD ATTEND Finding the time, space and budget to get out of the office to attend CPD events is always challenging. But it is worth making an exception for the Professional Lighting Summit, as it is the ILP’s landmark CPD event of the year. Here are five reasons why it makes sense to attend the Professional Lighting Summit.

FOUNTAIN OF KNOWLEDGE With this year’s ILP Professional Lighting Summit now just days away, it is your last chance to register and get involved in the important conversations and thinking shaping the lighting industry By Nic Paton

T

he findings of the ILP/CRT National Lighting Survey discussed on the previous pages will undoubtedly be a key conversation point at the ILP Professional Lighting Summit later this month in Newcastle upon Tyne. This year’s Summit, which is being sponsored by Designs for Lighting and Lighting Reality, will take place from 12-13 June and will be held at the Life Science www.theilp.org.uk

Centre in Newcastle upon Tyne. Liz Hudson will be presenting the key results from the survey, as well as encouraging ILP members to reflect upon the findings and what it means for the industry. As we highlight on the cover this edition, another speaker set to make a splash this year is Charlie Wadsworth, commercial director at Light Projects. He will be examining the challenges and opportunities of underwater lighting, including current considerations for underwater and wet area lighting, such as swimming pool, spa and fountain lighting. A further addition to the final speaker line-up are Graham Smith from the HEA and Peter Burbage from Ringway (and a member of the ILP’s technical panel), who will be exploring the CDM regulations through the whole project lifecycle. The Summit will also, of course, see President Colin Fish pass over the reins to current Senior Vice President Anthony Smith, during which he will present an overview of progress made by the ILP during the year, especially around the transition to the new Lighting Delivery Centres and National CPD curriculum. For a preview of this, turn over to page 16.

WORKSHOPS AND EXHIBITORS

Don’t forget, there will be a range of practical CPD workshops running across the two days. The exhibition hall will be open throughout the Summit, with delegates encouraged to visit during the regular breaks between the presentation sessions. This year a special delegate day rate has been agreed of just £90. For full details, go to www.theilp.org.uk/summit

1. Credibility. The Summit will help you to build credibility as a driven lighting professional by keeping up-to-date with the latest developments and thinking – a valuable benchmarking exercise. 2. Kudos. The Summit will enable you to learn from the best – our speakers all have real-life success stories to share. 3. Practical support. The Summit will allow you to gain practical advice and insight on areas of specific relevance or interest from our range of interactive workshop sessions. 4. Networking. Through the Summit you can build your professional network and meet with new and existing suppliers – a great opportunity to make cost and efficiency savings for your organisation. 5. Peer research. The Summit will be an opportunity to research what your peers are up to and make sure that your organisation always stays one step ahead.

A SPRINGBOARD FOR THE FUTURE

This month’s Professional Lighting Summit in Newcastle upon Tyne will see the formal launch of the ILP’s new-look network of Lighting Delivery Centres and a National CPD Curriculum. ILP President Colin Fish explains what members can expect By Colin Fish

June 2019 Lighting Journal

THE IDEA BEHIND THE NATIONAL CPD CURRICULUM IS ABOUT TRYING TO DELIVER A CORE, CONSISTENT SUITE OF HIGH-QUALITY CPD. IT IS ABOUT TRYING TO MAKE SURE OUR MEMBERS ARE GETTING THE EDUCATION THEY NEED TO DO THEIR JOB, AND TO DO THEIR JOBS BETTER

O

ne year ago, at the 2018 Professional Lighting Summit in Thame, we revealed the structure of the newlook ILP, with our longstanding regional committees set to be replaced by a new network of ‘Lighting Delivery Centres’ (LDCs) and members gaining access to a new National CPD Curriculum (A new-look ILP, Lighting Journal, June 2018, vol 83 no 6). Since then, the behind-the-scenes work of implementing this new structure has been ongoing, and our Implementation Panel has been working hard to make the vision and ambition of this new structure a reality. It has been a collaborative process and we now have an operating framework in place for both the LDCs and the new National CPD Curriculum. In fact, I am pleased to say the first LDC meeting, of the Birmingham LDC, is due to take place in July, with the other LDCs around the country set to follow suit over the coming months. So what has changed and is changing, and what will this mean for ILP members?

THE LDC STRUCTURE

Let me explain, first, about the LDCs. Each LDC will be led by a committee of eight people, comprising a Chairman, Immediate Past Chairman, Vice Chairman, Secretary, YLP member and three other committee members. There is no longer a role of Treasurer in the new set-up. But following consultation with the LDC chairs, there is still a Bursar role, which most commonly will be undertaken by the LDC secretary. There are seven primary LDC sites around the country – Birmingham, Bristol, Durham, Ireland, London, Manchester and Scotland. These have been chosen

because of their ease of access as transportation hubs. Virtually all – 97% – of ILP members therefore should be within 50 miles of their local LDC. But that geographical spread is only half the story. The seven hubs will be the location for each of the LDC’s major CPD event during the year. But we are encouraging LDC chairs and committees to look at their area and identify additional areas where they can put on and run CPD events. The regional boundaries that used to be in place have also gone, with the result that any member can go to any event regardless of the location. That’s part of the beauty behind the new structure. Using London LDC as an example, if it held a National CPD Curriculum talk on, say, electric vehicle (EV) charging points and you could not get to it, even if it was your usual LDC, there will ideally be opportunities to attend it elsewhere in the country. At a governance level, we’ve recognised that members who volunteer their time to work for the Institution do so on top of their busy ‘day job’. So, we’ve worked to create a framework that eases the administrative burden on volunteers. All the time-consuming banking and day-to-day raising of invoices that regional committees used to have to do will now be handled through Rugby. This, we hope, will allow the LDCs to concentrate on creating and delivering quality technical and CPD sessions. Another important piece of feedback we

p ILP President Colin Fish speaking at last year’s Summit in Thame. In Newcastle he will be handing over the reins to Senior Vice President Anthony Smith

have taken on board from the LDC chairs and our wider membership is the need to preserve the social element of regional activities. Social peer-to-peer networking is a key – and important – part of membership and always will be. Therefore, each LDC has it in its gift to continue to offer social events as it sees fit. The only proviso is these events need to be self-funding, whether through ticket sales or sponsorship. For example, if a social event will cost the LDC £50 a head to put on, the ticket price should be £50 a head as a member unless sponsorship is obtained. The monies the Institution spends from central funds on LDC activity will then focus on promoting and delivering technical competencies for our members. To this end, technical CPD activities will be free to attend for members, although there may be occasions where a small charge is made, for instance for additional catering.

THE NATIONAL CPD CURRICULUM

The second key strand of the new-look ILP is our new National CPD Curriculum. This is, as its name suggests, a national ‘suite’ of CPD talks, presentations and papers that LDCs will be able to tap into over the course of a year. www.theilp.org.uk

The new-look ILP

A call for papers went out late last year and we had a good take-up of offers on a wide range of subjects. At the last LDC implementation meeting in March a final list of topics was agreed that LDCs will be able to host at their upcoming events. The idea behind the National CPD Curriculum is about trying to deliver a core, consistent suite of high-quality CPD. It is about trying to make sure our members are getting the education they need to do their job, and to do their jobs better. But – and this is important – we do not want to deter LDCs from finding and sourcing local topics and speakers. After all, great CPD is also about drawing members in from the local level who have an understanding of key topics for their area. Moreover, the actual content of the National CPD Curriculum is very much – and always will be – driven by members. So if you tell us you need technical content on, say, electric vehicle charging points and the new wiring regulations we will work to deliver that. We will do this in a number of ways. We will put out a call for papers on these topics to the membership to see if there is anyone willing to give a paper on that subject that can be added to the curriculum. Alternatively, we might consider whether one of the Vice Presidents (perhaps our Vice President Technical) or our soon-tobe-appointed Technical Director could write or deliver a presentation. Alternatively, we might go out to the wider industry to see if there is anyone

with a suitable presentation that could be used.

SIX MONTHS’ OF EVENTS

We have got to a point where the National CPD Curriculum is a pool of papers and presentations able to be used by LDCs. As content will obviously need to be refreshed and renewed regularly, in the future papers will be vetted by our Technical Director or Vice Presidents. This will be to make sure papers are not too commercial, that they are giving good technical content, and that they are fit for purpose. Our goal is always to have at least six months’ of upcoming events and topics available to view by members on the ILP website, in the newsletter and here within Lighting Journal. All the established ILP CPD events, for example Lightscene, Light School and of course the Professional Lighting Summit, will continue. We will also seek to use the National CPD Curriculum as a tool to engage with industry partners, such as the CIHT, HEA, APSE, LoLEG and others. Eventually, we would wish to see a reciprocal relationship where the ILP is able to provide papers on lighting matters to partners and they reciprocate with papers on, say, asset management to ILP members. We can start learning about other people’s issues and solutions and vice versa. This is an exciting time of change, an exciting progression, for the ILP. But please do feed back on

the process. The ILP is the members’ Institution, so tell us what you want. Finally, I’d like to thank all of the members and the past members of council and the LDC Implementation Panel for all the hard work and effort they have put in to get us to this point where, in Newcastle upon Tyne later this month, we’ll be in a position formally to launch the restructure of the Institution. This is all about just getting the Institution to a position where we are refreshed for the future – I look forward to talking to you all about it at this year’s Professional Lighting Summit in Newcastle.

Lighting research: The 2019 European Lighting Summit

VALUE CHAIN Allan Howard reports for Lighting Journal from the 2019 European Lighting Summit, where papers discussed how to communicate the ‘value’ of light and lighting to society, the application of human-centric lighting, how to improve lighting within schools and the electrical load challenges posed by the rapid growth of ‘smart’, connected cities By Allan Howard

ighting Europe hosted the well-attended 2019 European Lighting Summit in Brussels in March, which for this year was based on the theme of delivering ‘#BetterLighting’. This article intends to provide a brief overview of some of the key papers that were presented, in particular looking at latest research and thinking around the application of human-centric lighting, how lighting in schools can be improved, and the Europe-wide problems being experienced by distribution system operators (DSOs).

HUMAN-CENTRIC LIGHTING: WHAT’S NEW?

Presented by Dieter Lang of Ledvance Human-centric lighting (HCL) has now been defined as ‘lighting that supports the health, well-being and performance of humans by combining the visual, biological and emotional benefits of light’ [1]. We are only at the early stages of understanding and applying HCL, having accepted the earlier Lighting Europe www.theilp.org.uk

considerations of bringing the value of light to society; these being energy efficient lighting, followed by light for sustainability and using intelligent lighting systems as represented by the opposite chart (figure 1). All of this is also underpinned by the concept of the ‘circular economy’, where luminaires are serviceable, can be upgraded, repaired and broken down for recycling, thus supporting the European Union’s ‘right to repair’ for goods. What this also means is we are moving away from the approach of luminaires with integral light sources, where the whole luminaire has to be replaced should a single LED stop emitting light. Dieter’s presentation highlighted that there are essentially four main pillars that support effective HCL. These are: • Science. The non-visual effects of light have been proven with scientific evidence that light is relevant for human behaviour, health and wellbeing. The knowledge we have is more than sufficient to start HCL considerations, even if everything is not yet fully covered.

• Guidance. We have a definition for HCL, but how can we transfer the scientific knowledge into applications and provide information for users, designers and their stakeholders? • Standards. To design for HCL we need standards with respect to the measurement of light relating to the non-visual effects of light and we need to understand where this measurement needs to be considered [2]. • Regulations. We require mandatory rules on the application of HCL in the public realm, workplaces, within education, elderly care, human care and so on. This requires an extension of the vision-orientated regulations to include the non-visual effects. Basically, humans have developed under natural light but we now spend an average of 90% of our time in buildings, and HCL is more related to natural light levels than those we find under artificial light. This is not to say that HCL has no effect under artificial light, but the right lighting levels are required for it to

become effective. These levels are an area of consideration at this time and CIE document S026 System for metrology of optical radiation for ipRGC-influenced responses to light is a good starting point. What really needs to be considered is the quantity of light that falls on the human retina and not necessarily the lighting levels on the working or task plane. We know, for example, that with increasing age less light reaches the retina. So, for HCL we are not just talking about a defined lighting performance but also a consideration of the light source and of the human receptor, as shown above in figure 2. The opposite table (figure 3) was presented, and is based upon CIE S026, considering melanopic-equivalent daylight illuminance and typical desk lighting levels. An upcoming EN document will look to support and enable HCL. The indications presented at the summit are that an average illuminance of 750 lux on the office working plane is probably insufficient to provide HCL; whereas 1,000 lux is closer to achieving the required HCL performance (based upon 6500K LEDs).

There are also considerations that illuminance is perhaps not the right measurement metric. The discussions and research on this continue.

BETTER LIGHTING IN SCHOOLS

Presented by Olle Strandberg, an IT strategist within the Department of Internal Service, City of Malmö, Sweden It may seem strange that this paper and research has been undertaken by an IT strategist, but increasingly buildings are information hubs, and lighting is becoming an integral part of a building’s IT. Olle presented more than ten years of research into the effect of lighting on education within a school in Sweden. The research had been predicated on the reasoning – also highlighted of course in Dieter’s presentation – that humans evolved to operate under natural lighting, yet we now spend the majority of our time within buildings mainly under artificial lighting. When the project commenced there was very little in the way of equipment and control systems to support an HCL-based

lighting installation, and lighting was still more about energy efficiency than design and task requirements. In 2015 a trial installation was agreed for a school classroom; this used LED luminaires with colour temperatures between 2700 and 5800K controlled by DALI and Crestnet protocols. The lighting level and colour temperature profiles were based upon joint discussions with teachers and lighting designers. The approach was to provide soothing lighting at the start of the day and then adjusting the illuminance and colour temperatures during the morning lessons as indicated within figure 4 overleaf. So what did the pupils think? Pupil feedback was that the classroom was better than before. They said they felt more alert and concentrated better; their eyes felt better; the room felt bigger and more spacious. They also said they wanted the same lighting for the other classrooms! From the teachers’ perspective, the feedback was that, under the HCL scheme,

pupils could concentrate better; there was no visible difference from natural light; the new scheme was easy to control via the control panel; and (similar to the children) the teachers found it hard to go from the HCL classroom back to working in the old fluorescent lit rooms. Therefore, Olle outlined the lessons learnt and being put into place were: • This is an IT system, therefore consider it as such • Choose a system that requires the least maintenance and is straightforward to control • Ensure everyone is educated in how to use and maintain it. Since the trial, the application has been taken up by more schools and conference facilities. The approach is not considered expensive and the project indicates a cost of circa €3,688 per classroom (on a basis of nine luminaires per classroom), considered a small price to pay for providing the right education environment. www.theilp.org.uk

SMART CITIES AND ELECTRICITY DISTRIBUTORS

24

Presented by Roberto Zangrandi, secretary general, European Distribution System Operators Group This presentation by Roberto Zangrandi was designed to bring a perspective on smart cities from the European DSO (Distribution System Operators) Group E.DSO. DSOs are responsible for the electrical distribution network across Europe and their traditional role has been concerned with network planning, management and operation as well as customer connections, metering and quality of supply. This is now changing to include smart metering, market facilitation, renewable energy supply connections, big data management as well as third-party access and smart network planning and grid operation. Therefore, DSOs are looking to ‘catch up’, conceded Roberto. For example, they did not fully foresee the uptake and requirements for electric vehicles (EVs), perhaps expecting very little impact on the electrical network. The requirement that EVs need street charging points, with a customer expectation of being able to charge quickly resulting in electrical loads per point of up to 750kW, has become a network capacity issue. EVs are not the only impact on their network either, as we are now of course seeing growing uptake of ‘smart’ city technologies, including smart motorways and not forgetting, within the UK, the proposed requirement for new houses to be heated by electricity and not gas. There are therefore a lot of electrical loads that now need to be connected to a source of electricity (power station, solar/ wind farm, battery storage and so on) via a DNO network, and this is increasingly becoming recognised as potentially an extremely big problem. Roberto advised the delegates that the

group was proposing six key areas for development. 1. Business models for ‘islanding ’ of microgrids. 2. Efficient controllable comfortable demand response models. 3. Flexible and viable storage solutions. 4. Cross energy carrier testing. 5. Flexible EV charging solutions. We are, of course, already seeing this. If, for example, there are six charge points in a street and all are being used, the system reduces their performance to balance the load; the result is the vehicles will take longer to change. But this, of course, is not what the customer would really wish nor expect to see. 6. Digitised responsive grid automation. Within these are obvious cybersecurity concerns, Roberto highlighted, and the solutions will require cross-sector co-operation and a good future understanding of electrification. These will require: • Energy innovation. For example, high-efficiency PV solar panels, cheap and powerful, versatile batteries. • Digital innovation. For example, new market frameworks, co-ordinating

schemes and data exchanges. • Climate regulation. For example, targets, standards, carbon impact, compliance, and so on. • Energy regulation. For example, increasingly complete energy networks, usage rules and tariffs and so on. So, a challenge ahead which is impacting on our current service provisions but also our future.

CONCLUSION

Following the summit, Lighting Europe identified the following four priorities as measures to bring about #Betterlighting: • Better lighting enforcement • Better understanding on the ‘value’ of lighting • Progress on implementing circular economy thinking • Better understanding of EU legalisation impacting on lighting More information regarding Lighting Europe can be found at www.lightingeurope.org Allan Howard BEng(Hons) CEng FILP FSLL is technical director at WSP

Lighting research: The Sydney Street Lighting + Smart Controls Conference

SMART DOWN UNDER Sydney’s Street Lighting + Smart Controls Conference in April challenged the region to kickstart its connectivity ‘journey’, including hearing inspiring stories from Chicago and Dunedin, among others. Nigel Parry was there and reports back for Lighting Journal By Nigel Parry

T 26

he Street Lighting + Smart Controls Conference in Sydney, Australia took place over April 02-04. It was the fourth conference arranged with SLP and, with the theme ‘Get Smart City Ready’, the focus was very much how to kickstart LED and connectivity issues in Australia and New Zealand. The first two conferences were held in Auckland and really helped move the New Zealand market to adopt LED technology and become number two in the world (behind the UK) in percentage of connected streetlights. The latest conference was held at the new International Convention Centre (ICC) in the heart of Darling Square at Darling Harbour (pictured above), and was well-attended with some 200 attendees. The organisers attracted speakers from not just Australia and New Zealand but around the globe, predominately from the USA and Europe. The two-day agenda was full and there were too many papers to cover in the short space we have within Lighting Journal, so this article will be a snapshot of some of what stood out for me.

CHICAGO’S ‘SMART’ STORY

One noteworthy example was a video link presentation by Danielle DuMerer, chief information officer and commissioner at the City of Chicago’s Department of Innovation and Technology. Her talk was on ‘How the city of Chicago sees smart street lighting improving urban liveability’ and was notable because Chicago is probably the US city closest to being able to call itself a true ‘smart city’. The lights are all LEDs and all www.theilp.org.uk

communicate, but the city has also fixed a variety of sensors on its network that provide data on air quality and temperatures and this is all feed back into an open public platform that anyone can view. Anja McAlevey, senior transportation planner at Dunedin City Council in New Zealand, explained what it is about to undertake after many years of preparation. Essentially the city is to convert to LED with CMS and Anja eloquently described the process they have undertaken and the consultation with many parties to ensure this beautiful part of the world is enriched by the new lights. After lunch we had Dr George Brainard, director of the Lighting Research Program at Thomas Jefferson University in Philadelphia, who provided an update on the latest research around light and human circadian rhythms. One slide in particular reminded us that below 500 lux the blue light effect has not been found to have an influence on melatonin supply. Dr Brainard also went into more detail about how NASA is taking this research into space and fitting new lights that change their spectrum and output during the day. The aim is to ‘energise’ the activity the lights have during the day, with a higher blue content and high levels (1000+ lux), but at ‘night’ this drops to only 20 lux and higher red content. He was followed by another inspiring speaker, Professor Fred Watson, astronomer-at-large at the Australian Astronomical Observatory in New South Wales. Professor Watson was obviously keen to protect the dark skies and recognised that new lighting technologies offer a great opportunity to improve the current orange

skyglows from sodium. He also encouraged the audience to adopt better controls and consider LEDs with less blue light.

ADAPTIVE LIGHTING

Dr Ron Gibbons, director at the Virginia Tech Transportation Institute in Virginia, USA, opened up a popular section on adaptive lighting. He explained some of his research into crash data, noting that New Zealand kept the best records in the world. He also confirmed that over-lighting provides no benefit to crash reductions but did note that using 4100K LED provided an extra 20% target detection and colour recognition compared to other LED CCT and compared to HPS lamps. Dr Gibbons proposed that 3000K on residential roads is appropriate and traffic routes would benefit at 4000K. Dr Dionyz Gasparovsky, division director transportation and exterior lighting at the International Commission on Illumination (CIE), Slovakia and CIE Division 4 chair, updated the audience on the latest CIE work in this area and the formation of a new committee to address this new area. Finally, at least for me, it was great to see Craig Morris, street lighting engineer from Doncaster Council, give an enthusiastic talk about the authority’s switch to LED, and how it is moving to having adaptive lighting linked to traffic flows across the area. Craig’s tips on what to do or not do were well noted by the audience, who needed to hear that there are tried and tested paths to achieving the improved lighting and energy saving that Doncaster has achieved.

his year, 2019, is a year of celebrations and congratulations. Why? Because architectural lighting has truly come of age – the International Association of Lighting Designers (IALD) is celebrating its 50th year. What started in 1969 as a small group of passionate and dedicated architectural lighting designers in New York grew almost instantly into an international association. Folklore has it that Phil Gabriel FIALD attended these early meetings and, as a Canadian, the meetings therefore became international. True or not, that little ‘I’ in IALD is still something the association holds most dear.

CERTIFIED LIGHTING DESIGNER PROGRAMME

Our membership is now nearly 1,500 members, which is an increase of 44% since 2014. We now have members in more than 60 counties, and we are listening to the different challenges we all face in our domestic environments and working outside of them – and, yep, that even includes Brexit. More than five years ago the IALD and other associations from around the globe, led by a membership desire, sought to create a qualification that would act as a bench mark of competency. It was not a straightforward process, as www.theilp.org.uk

significant wordsmithing had to take place as the legalities of charters and such accolades in different counties need different permissions and can be restricted domestically. But the result, the Certified Lighting Designer (CLD) programme, is now supported by all the major lighting authorities in the world. There are now currently 60 CLD-approved lighters around the world and, in April, a gathering from the programme came to London to promote and talk about it as a qualification. The architectural lighting firm ERCO kindly offered its showroom as a venue and we came together to discuss the merits of the scheme and how we could get more people involved, with presentations made by Paul Nulty, founder of Nulty+, and Professor Peter Raynham, of UCL. Peter has also kindly offered to visit design studios around the UK to explain about the CLD and help with the application process, which can sometimes seem daunting at first.

SUPPORTING ACTIVITIES WORLDWIDE

In its 50th year, the IALD continues to support events around the world. One such programme, and which is also celebrating a notable anniversary, is ‘Lights in Alingsås’, which is 20 this year. A team of dedicated lighting designers

has been creating a lighting festival in the Swedish city since 1999 and the festival has grown so much that it now attracts a whopping 70,000 spectators from October and November. This year’s festival will run from 27 September-03 November, and more details can be found at www.lightsinalingsas.se/en Each year, six international workshop heads take hold of six sites to create lit scenes which tell their story through the power of light. They are able to do this with help of their eager lighters; who incidentally come from all over the world. It is a life-changing experience for the workshop heads and the participants. And for any of you reading this with experience in lighting workshops I urge you to apply for 2020. The IALD is proud to support this programme and watch it expand. Another notable date to celebrate this year was the equinox-based ‘Chase the Dark’, which took place on 20 March. It gave people the opportunity to enjoy the light and dark at the same time around the world. All industries have recognised the need to be inclusive and share equal rights, so the equinox seemed like the perfect day to explore that balance. Given it was also the IALD’s 50th year,

we ran with the title ‘50 Shades of Colour’ and ran an event in London hosted by BDP and supported by Architainment and Rosco filters. Participants got to play with a range of LED torches and coloured filters to create lit scenes. It was a playful night with a turnout of more than 60 people coming from the fields of architecture and lighting. Our activity from this can be found on Twitter and other social media platforms using #ialdchasedark Finally, I for one am very much looking forward to our annual conference this autumn. This year Enlighten Americas will be in Albuquerque from October 03-05, and more details can be found at www.iald.org The IALD will continue to work closely with the ILP and – with 50 years now under our belt – we look forward to supporting all lighting designers, from students to senior lighters, on our mission to improve the quality of light in the built environment.

London’s ‘Illuminated River’ project

SPANNING THE MOMENT The ILP’s 11 volunteers are looking forward to London’s ‘Illuminated River’ public art project becoming a reality from this summer. And the logistics and complexity of the ambitious project have been challenging, as this update shows 30 By Nic Paton

A

s Lighting Journal reported back in February, ILP volunteers are set to play a key part in the creation of the ‘Illuminated River’ public artwork that will be lighting up (initially) the capital’s London, Cannon Street, Southwark and Millennium bridges (Thames Crossing, February 2019, vol 84, no 2). Conceived by American light artist Leo Villareal and British architects Lifschutz Davidson Sandilands, the project is being delivered by the Illuminated River Foundation. Jonathan Gittins at Atelier Ten Lighting is responsible for providing the technical lighting design, and discussed the project at the ILP-backed Light School back in February.

ENGINEERING CHALLENGES

The sheer scale and practical complexities of the project are becoming clearer the closer we get to the first bridges going ‘live’. For example, Jonathan, in a blog post on the Illuminated River website has described the challenges of ensuring the lighting design minimises light pollution, skyglow and light spill into the river and its surrounding areas and neighbourhoods. www.theilp.org.uk

The team carried out a complete a luminance survey of the Thames, in what is believed to have been the first such survey undertaken for a broad stretch of the river. From this, they were able to plot luminance levels along the river, assessing the brightness distribution on and around the bridges in order to identify the most appropriate luminance level for each bridge. ‘For this project, we wanted to make sure we were using just the right amount of light on the bridges so that they will stand out against, but not overpower their surroundings. Equally, we are acutely aware of the potential harm that spill light can cause and so wanted to ensure light is targeted on the bridges and not into the river or surrounding areas – the right kind of light in the right places,’ explained Jonathan. ‘In many cases, we found that the bridges were lit to very high levels and will be working hard to lower these levels without loss of visual impact,’ he added. A light spill survey was also carried out to assess how much direct light from the bridges was currently spilling on to the Thames, with intriguing results. ‘We were shocked by some of the

current levels of light spill. Albert, Tower and London Bridges all have very high levels of spill which are significantly over recommended levels. Albert Bridge, in particular, throws out more than 20 lux, the kind of light levels you would expect to find on a motorway, not a river. We are confident that the design of the new lighting scheme will be able to reduce this spill by three quarters,’ said Jonathan. ‘We also discovered that in many areas, such as the area surrounding Southwark Bridge, a lot of the light spill into the river was coming from streetlights and over-lit buildings.’ To that end, the team has designed custom shields that will be fitted to the lighting and adjusted to significantly reduce spill light into the river. In a more recent update, FM Conway project manager Mark Holland also provided a fascinating insight into some of the

behind-the-scenes engineering and logistics challenges of the project. As he wrote: ‘Everything has to be thought about, from the exact shade of our fixings to the existing sensitivities of these historic bridge structures. This is also what is so inspiring about Illuminated River; for the first time the lighting on the Thames bridges is being approached with a cohesive, artistic vision that reveals and celebrates the architectural and historical identities of the bridges.’ In terms of some of the practicalities, Mark highlighted that the cabling for the Millennium Bridge now feeds vertically down into the City of London School. The historic Fishmongers’ Hall on the north bank of London Bridge has also allowed the team to have special access through its site. ‘The river itself has been a most unusual building site and a new experience for us.

The Thames is a busy working river, which can make it a particularly challenging place to operate, not to mention the fact that the river itself is tidal,’ explained Mark. ‘We have got to know the local boat companies on the Thames, and have made sure our working schedule is convenient for them. In practice, this means complex planning of which bridge arches we are working on, and how we synch the bridge arches as we move down the river. Every day, we are transporting our own materials by river, in order to cause minimal disruption to bridge users. We have got to know the tidal patterns of the Thames, which rise and fall twice a day, up to eight metres. ‘We have had to come up with entirely new inventions, such as our encapsulation systems (protective netting).

EXTENSIVE COLLABORATION

Such a high-profile project has also meant extensive collaboration with many partners and stakeholders, including the City of London and the local London boroughs, the Port of London Authority, tourists, Londoners and pedestrian and vehicular commuter traffic across the bridges involved. The Millennium Bridge alone, for example, has more than 20,000 people crossing it each day, so one of the challenges of the project has been in working around this steam of people while keeping the bridge open and, as the number one priority, keeping pedestrians safe. ‘The complexities around this high-profile, interdependent job are as fascinating as they are challenging. The individual materials needed to deliver this project have been outstanding. We have probably used around 2,000m of cable tray on London Bridge and 10,000 rawl-bolt fixings to hold the cable in place,’ explained Mark ‘So vast have been the requirements that we have created a temporary national shortage in stainless steel cable tray and we have used everything in the country within a reasonable distance! ‘Limited space on the bridges means that, each night, we have to move all our working materials back to our depot in Mandela Way, Bermondsey. You may be thinking that this doesn’t seem too great a challenge, but when this is moved via wheel-barrow back and forth on Millennium Bridge which is nearly 350m long, well… we’ve provided our operatives with “fitbits” as they will be

smashing their targets,’ Mark said. ‘The logistics of the programme continue to challenge me. The need for precise timing, the strict deadlines, the stakeholder management, the infrastructure complexities and materials innovations ensure there is never a dull moment, however, this is also what excites and drives me and has given me a

whole new appreciation for the bridges of the River Thames,’ Mark added. Regular updates on the project are being provided through the website www.illuminatedriver.london/news both on the practical, day-to-day challenges but also wider architectural, artistic and historical discussions around bridges, architecture and design.

Grimshaw and Norman Wilkinson. The paintings have been selected by the Illuminated River artist Leo Villareal from the gallery’s collection to complement his vision for the Thames bridges. According to the gallery organisers, the Thames paintings selected by Leo ‘represent the atmospheric shifts of the river environment at different hours of the day and through the seasons’, taking inspiration ‘from the natural and social activity of the river; barges and

boats moving cargo and people, cars, pedestrians, trains, and the ebb and flow of the tides.’ The Illuminated River display is free to access and will be presented in the Temple Room. Entry to the Architecture of London exhibition costs £10 for adults and £7 for concessions. The Guildhall Art Gallery is in Guildhall Yard, and the nearest tube stations are St Paul’s, Bank and Moorgate.

‘ILLUMINATED RIVER’ ON DISPLAY Anyone keen to find out more about Illuminated River and how it connects with London’s architectural heritage should head to London’s Guildhall Art Gallery over the summer. This is because until 01 September architectural drawings and animations from the project are being included in an exhibition entitled ‘Architecture of London’. As well as the Illuminated River display, the exhibition includes historic Thames paintings by artists such as Frank Brangwyn, John Atkinson

q The distinctive, twisting Evolution Tower

MOSCOW CENTRAL With its distinctive twisting shape, tilting surfaces and temperatures extremes between summer and winter, lighting Moscow’s 225m, 55-floor Evolution Tower, home to the Russian pipeline giant Transneft, proved something of a headache By Nic Paton

T

he Evolution Tower skyscraper in Moscow was designed by architects Tony Kettel and Karen Forbes and built between 2011 and 2014. Because of its distinctive twisting shape, it quickly became a landmark in Moscow’s new urban (and rapidly rising) skyscape. In 2016, the 255m-high, 55-floor building was bought by the Russian stateowned oil pipeline company Transneft, and ever since has been the company’s headquarters building. Both the interior and exterior have been lit by products from iGuzzini, with the lighting design coming from Dean Skira of Skira Architectural Lighting. The building is lit entirely by LEDs and, argues iGuzzini, boasts one of the most sophisticated manwww.theilp.org.uk

agement and control systems on the planet. Looking at the exterior, first, the spiral structure of the building required the design and construction of a range of specific solutions.

TILTING GLASS SURFACES

The tower’s most distinctive feature is its media façade, said to be the largest in Asia. The height of the tower, its architectural structure, the materials chosen for the façade and the fact the construction had already been finished all set significant challenges. Given the twisting and tilting of the glass surfaces, products could only be installed externally using mountain climbing techniques, and there were very

few points they could be attached to. Moreover, the luminaires needed to be able to cope with being exposed to extreme temperature changes, as the temperature in Moscow varies from -40degC in winter to +40degC in summer. For these reasons, a solution was developed that installed the luminaires on the inside of the façade. Dean Skira wanted to create a screen effect on the outside of the building with a series of RGBW ‘dots’ that could be controlled individually, and which allowed colour and light intensity to be changed in order to create different effects, including the Transneft logo. A decision was therefore made to light the façade from the inside using an indoor product that would significantly reduce

installation costs and difficulties as well as maintenance expenditure. The product was designed so it could be attached to the uprights used for the roller blinds. This allowed it to blend in with the aluminium components of the façade as well as facilitating installation, thanks to pass-through wiring. The luminaire had to be capable of developing a level of intensity that would allow its visual effect to be seen from a considerable distance. It also had to offer the widest range of colours possible, evenly and without revealing the individual LEDs, as well as observing the overall power limits required to light the façade. The solution was a cylindrical luminaire with a consumption of 15W, fitted with an

RGBW LED circuit and a DMX RCM driver. About 3,600 ‘dots’ were positioned over the entire façade, thanks to a grid that becomes narrower between the 40th and 47th floor to display the company logo. The luminaires are installed on the interior surface of the façade’s multiple, insulated glass panels. In terms of management, the ‘dots’ interact with the control system (not supplied by iGuzzini) that is used for the building automation of the entire structure. Each ‘dot’ is connected to both power and control cables. The DMX RDM driver used for colour change management is compatible with the existing control system. It offered significant advantages in terms of www.theilp.org.uk

Workplace and exterior lighting

38

programming and management, as each luminaire, for example, had an auto-addressing function that avoided manually addressing 3,600 ‘dots’, as this (naturally) which would have taken a very long time indeed. The same lighting effect was guaranteed in the building’s technical areas by using luminaires with a higher protection level (IP65 rating). This, of course, ensures they can resist water released if the fire prevention sprinkler system installed in these areas is activated.

VARIED INTERNAL ENVIRONMENTS

Turning to the interior lighting, this also posed challenges, not least because the layout of the tower’s different environments – each with their own specific function, such as computer workstations, corridors, shared spaces and reception areas and so on – varied significantly, again because of the www.theilp.org.uk

twisting shape of the structure. The general contractor, Velesstroy, entrusted Dean Skira with the complex task of developing a lighting design that would offer a high level of visual comfort for employees and energy consumption of less than 5W per sq m, while also reflecting the importance, history and values of Transneft. This brief had to be created for rooms with variable sizes that are neither square nor rectangular, and whose glass walls tilt at different angles. Therefore, the lighting concept was based on low luminance luminaires. The positioning of these products was carefully researched to ensure the level of uniformity requested by the customer for the specific work areas was achieved. All the luminaires are DALI and therefore dimmable. They are also connected to a network of

presence and daylight sensors controlled by algorithms that are part of the structure’s building automation. The fact this project involved spaces whose size varied enormously led to Dean Skira choosing luminaires from iGuzzini’s ‘Laser Blade’ range, as it has a consistent style yet allows for requirements in different environments. The general preference was for shorter one-, three- and five-cell modules because they were extremely adaptable given their compact size. A bespoke five-cell Laser Blade adjustable wall washer luminaire was specifically created too. Vertical wall lighting was used to obtain an optimum, diffuse and homogeneous effect within the work environments where video screens were used. This also meant the low luminance luminaires could be properly integrated without creating shadows that were overly sharp.


June 2019 Lighting Journal

GLARE ELIMINATED

In some environments, underscore light lines with grazer effects were used and, in others, Laser Blade L adjustable luminaires fitted with wall washer optics were chosen to light the side walls vertically. In other areas, standard lamps were added to integrate and personalise the lighting. To soften the lighting effect in the work environments, on the other hand, an adjustable version of the Laser Blade L luminaire was installed that included special filters to broaden the luminaires’ light emission. To illuminate the corridors that join the various work areas (and which have glass walls on one side and masonry walls on the other) Laser Blade L adjustable luminaires were installed with twin general lighting and wall washer optics. The general lighting optic guarantees general lighting, while the wall washer creates uniform lighting on the side masonry walls. For these spaces, Dean Skira asked iGuzzini to eliminate glare completely. To achieve this, the wall washer luminaires were fitted with a new super comfort longitudinal glare control optic that blocks longitudinal glare completely. Along the corridors, the emergency lighting is created by Laser Blade inOut luminaires with an IP65 rating. These, again, are water resistant, so they will continue to operate if the fire prevention sprinkler system is activated. This also maintains the style of the luminaires throughout the different areas.

39

In the entrance halls, which are characterised by large, ample spaces, marble and elements depicting Transneft’s activities, Laser Blade System 53 luminaires fitted with high contrast modules were installed. A slight formal differentiation was adopted for certain areas used for special events and meetings. In these offices, recessed Laser and Laser Blade XS luminaires were fitted. Dean Skira wanted to give all these environments the same colour temperature and colour rendering (4000K and CRI 90),

which was achieved within the set deadlines. Finally, the entire building needed to use a flicker-free driver that did not disturb video communications as, because of the international nature of Transneft’s activities, video calls and connections are used daily in many of the workspaces. This request was also particularly important for areas with surveillance cameras. iGuzzini ensured that all the drivers provided for the interior lighting system therefore had this characteristic. www.theilp.org.uk

Emergency lighting

SAVE NOW, PAY LATER? For too long, emergency lighting has been viewed as the poorer cousin to the main lighting scheme, a necessary but unattractive extra cost. Lighting professionals need to be more vocal about how modern LED emergency lighting, luminaires and slim-line control gear fixtures can complement a scheme, as well as ensure it is compliant By Peter Adams

A

s most lighting professionals will know only too well, emergency lighting systems must not only be fit for purpose, they must also meet stringent safety and compliance standards. However, meeting these standards can impact financially, both in terms of the design and specification, through to the installation, and the ongoing maintenance of the system. This is why emergency lighting is so often portrayed as a necessary but unattractive part of the scheme. This article is going to emphasise the case that emergency lighting is, in fact, a safety-critical system and is a legal requirement within commercial premises, and this is something all of us within the industry should be standing up and saying out loud. www.theilp.org.uk

Too often one of the most fundamental aspects of building safety, the provision of an adequate emergency lighting system, can be overlooked. Short-cuts and corner-cutting, such as the specification of sub-standard components and ineffective maintenance schedules brought about by budgetary constraints can result in non-compliances. This in turn can compromise the safety of the building occupants, not to mention potentially resulting in prosecutions such as fines and custodial sentences, depending on the level of non-compliance.

BRITISH STANDARDS

With the extensive revision of BS 5266 - 1: Code of practice for the emergency lighting of premises (released May 2016 and brought into force in June 2017), the way designers

approach emergency lighting has fundamentally changed. Despite better-defined responsibilities and more detail on emergency safety lighting and standby lighting requirements, this area is now more complex, with greater scope for confusion between the various parties responsible for the design, installation, testing/commissioning and ongoing performance of the emergency lighting system. As with most aspects of health and safety, there are many national and international standards in place to ensure that systems can perform the tasks demanded of them. It is therefore imperative that the constituent components of the emergency lighting system are selected, designed and installed to the specific criteria within these standards, ensuring compliance and


June 2019 Lighting Journal

performance of both the components and the system as a whole. Within this, the code of practice BS 5266: 1999 – 2016 is an essential point of reference. Its accompanying standard, BS 5266 Part 7 - EN 1838: 2013, defines the minimum lux levels and photometric requirements when designing the emergency lighting scheme. Also important is the standard BS EN 60598-2-22: 2014. This is for luminaires used in emergency lighting and ensures they achieve the performance required whilst remaining electrically and mechanically safe. In addition, the European Application Standard with improved testing regimes, EN 50172: 2004, is a vital supporting part of the BS 5266 series. The design objective for any emergency lighting system is established by BS 5266 Section 5.2.1 which says that, when the supply to the normal lighting fails, emergency lighting is required to: • indicate clearly the escape routes • provide illumination along such routes to allow safe movement through the exits • ensure that fire-alarm and fire-fighting equipment can be readily located In sum, the British and European Standards provide guidance on the implementation of requirements and solutions, on sustainability and energy use, guidance on required equipment, lighting for specific specialist areas as well as guidance on the installation process, testing and commissioning – all of which need to be considered at the start of the design process. It is also important for the manufacturer to understand the intended environment for the luminaire in order to specify the correct safety components. Although there is currently no legislation covering the use of LSZH (low smoke, zero halogen) components, it is recommended that LSZH be used in fittings specified for use in large public areas where there is a risk of fire. This will minimise the risk from the after-effects of an electrical fire, such as gas and smoke inhalation. For example, after the King’s Cross fire in 1987, LSZH sheathing became mandatory for all the electrical wiring in London Underground stations.

COMPLIANCE

In order for an emergency lighting system to remain compliant throughout its lifetime, structured and effective maintenance is essential.

The system requires testing in line with the requirements specified in BS EN 50172, together with any remedial action identified by these tests. Routine visual inspection of the system is also fundamental to check for any changes to décor, colour schemes, fabric and structure together with any reparations which may impact the designed scheme. Unlike a fire alarm system, which is generally subjected to a simple, periodic audible test for functionality (albeit in line with an annual sub-contracted service contract), the maintenance of the emergency lighting system is more time-consuming if being undertaken manually, without the aid of an automatic test facility. The annual full discharge test of up to three hours duration may need to be staggered across different storeys and areas within the building, and this may be perceived as a costly and labour-intensive overhead. But, again, what value can be put on the health and safety of occupants? The effect of the emergency lighting is seldom seen until required and it is during these times, where the safe and immediate evacuation of the building is paramount, that we come to appreciate the true value of this safety critical system.

41

LUMINAIRES

The cumulative operating costs of emergency lighting can be considerable, and the choice of fitting should be considered in terms of their installation cost, longterm energy consumption and maintenance or replacement costs. LEDs, as is nowadays well-recognised, consume

June 2019 Lighting Journal

Emergency lighting

about 25% of the power of traditional lamps and offer excellent lumen maintenance, as the light output remains constant throughout its design life. The greatest cost benefit, however, relates to lamp replacement. LED lamps typically have a 50,000h rated life, ten times that of a typical fluorescent tube. Using LED emergency luminaires therefore will greatly reduce the maintenance costs of an emergency lighting system and they have a longer expected life and lower running costs than standard luminaires.

BATTERIES

42

Batteries are a further key consideration when it comes to emergency lighting. Batteries have an impact on the cost of luminaires intended for emergency lighting, with Nickel-cadmium (NiCd) batteries the preferred choice for self-contained luminaires, despite the fact they utilise a toxic metal. However, Nickel-Metal Hydride (NiMH) batteries offer a viable alternative with significant benefits over the Nickel-cadmium battery. The NiMH battery offers an energy density of two to three times that of the NiCd battery, meaning it can be a third of the size of the NiCd equivalent. Combined with an LED light source and appropriate charger this can result in a very compact package. Another significant benefit is the charging regime. NiCd batteries require a constant current charge. NiMH batteries, however, have an excellent rapid-charge capability meaning they can be given a boost charge followed by a trickle charge. This results in long-term energy savings, so reducing ongoing costs.

TESTING

Statistical evidence indicates that regular testing and maintenance of emergency lighting systems is not routinely carried out by many organisations, as it is laborious and time-consuming, and therefore expensive. However, the fines for non-compliance are more so and eventually puts lives at risk. Testing of the emergency lighting system should be carried out at regular intervals by a qualified person. The tests must be carried out in line with the schedules outlined in BS EN 50172. These are outlined as below: • Daily. Visual check that all charge indicators are lit on and check lamps on all maintained luminaires are working. www.theilp.org.uk

p Testing of the emergency lighting system should be carried out at regular intervals by a qualified person.

But statistical evidence suggests that too often it is not routine

• Monthly. A monthly functional test is designed to simulate a failure of normal lighting for sufficient time to allow all emergency luminaires to be checked for correct operation and signs of damage or deterioration and the results recorded in a log book. • Annually. A test simulating the failure of the normal lighting supply for the full emergency duration (typically three hours) to ensure the emergency luminaires can function for the full duration whilst maintaining their declared emergency output or ballast lumen factor figures. During this test, the batteries will be discharged, and the luminaires will not be fully operational until they have had time to recharge. Therefore, this test is normally carried out whilst the building is unoccupied and at periods of low risk.

the lifespan of the unit can be considerably increased, so reducing long-term maintenance and replacement costs. Keeping emergency lighting luminaires clean is also vital to lighting efficiency. Over time dirt, grease and the build-up of insects inside the light fitting can reduce the light levels and can reduce the illumination by up to 30%, potentially falling below minimum lighting levels. This could mean a test failure and result in a non-compliance.

MAINTENANCE

• Self-test emergency luminaires. These provide simple ‘stand-alone’ automatic testing and the result of the test is indicated through a bi-colour LED on the luminaire. Monthly checks will still need to be carried out however by the responsible person, and the test results recorded and entered into the log book. However, the benefit of this type of system is that the person recording the information is not required to be qualified, as they will not be testing the system manually.

Traditionally, industry practice has been to replace the whole emergency fitting if it fails the annual test, as it has been believed this is more economical than isolating the circuit to replace the faulty component, usually the battery. However, this often results in emergency fittings being replaced every three to four years. But at Mackwell we would argue that, by choosing a fitting that allows for easy removal for repair and upgrade and an accessible battery drawer,

MONITORING SOLUTIONS

There are systems available that will make the testing process easier and less expensive. The upfront costs are similar to installing a standard emergency lighting system but the payback is the long-term maintenance and testing cost savings. These solutions include:

responsible for ensuring that the ‘responsible person’ has been properly trained. The Regulatory Reform (Fire Safety) Order 2005 (to give it its full name) requires the installation of emergency and safety lighting and Article 12 of the regulation stipulates that: ‘Emergency routes and exits must be indicated by signs, and emergency routes and exits requiring illumination, must be provided with emergency lighting of adequate intensity in the case of failure of their normal lighting.’ Any breaches of the Order are likely to result in the person responsible facing fines or imprisonment.’

CONCLUSION • Automatic test systems. These connect the emergency luminaires to a remote-control panel that collects the results centrally. These systems provide 24/7 monitoring, self-testing and reporting, including remote access to the status of every fitting, automatic record keeping and fault notification. These systems use a low voltage communication signal via an interface such as DALI and can be easily retro-fitted, providing regulatory compliance with minimal effort.

SPECIFICATION

Compromising on the specification of a fitting at installation can lead to long-term maintenance issues, affecting health and safety. It is a requirement that luminaires chosen for self-contained emergency lighting include a local indicator that is visible in normal operation. These indicators are a valuable aid to maintenance in the first instance, as they provide an immediate indication of the health of the emergency luminaire and that the battery is being charged. If the indicator is green, the luminaire is healthy. They do not, however, negate the requirement for regular safety checks. Emergency lighting systems should be maintained on a regular basis to ensure they are fully functional, the batteries are fully charged and that their light sources remain operational. These checks should be carried out by a suitably qualified responsible person as determined in the fire safety order and the fire safety log book should be updated subsequently to each test. This will ensure that all fire safety legislation is adhered to and that the emergency lighting system remains fully operational, meeting fire safety requirements.

LEGAL IMPERATIVE

Since the introduction of the Fire Regulation Reform Order in 2005, the legal imperative for installing emergency lighting systems is the same as for fire alarm systems. Failure to comply with the correct installation of emergency lighting and to maintain the system could cost a business dearly. If fire authorities discover that the emergency lighting system is not fit for purpose or non-compliant, and the system has not been properly maintained, the company could receive a hefty fine, often tens of thousands of pounds. If neglect is proven in terms of the standard of the installation or maintenance of emergency lighting, and leads to injury or worse, the ‘responsible person’ could face a custodial sentence. The law is drafted to place ultimate responsibility squarely with the owner of the property, but it also names in the act a ‘responsible person’, who the owner of the property can appoint and delegate that responsibility to. That person is then required to make the necessary provision for emergency lighting, including undertaking risk assessments and having a proper fire safety schedule mapped out. Even if the owner delegates the responsibility, they are still

For too long, emergency lighting has been viewed as the poorer cousin to the main lighting scheme, something necessary as a legal requirement but ultimately detracting from the general ambience, and interfering with the aesthetics of the design whilst incurring extra expense. It needn’t – and shouldn’t – be like this, however. First, as we have seen, to compromise on emergency lighting is to compromise on the Health and Safety at Work Act, the Fire Safety Order and, ultimately, individuals within your building. Moreover, in an era of discreet LED light sources together with slim-line control gear fixtures, architectural designs and effective spacing tables, emergency lighting luminaires, if used sympathetically, can often end up complementing the designed scheme while bringing comfort and reassurance to building operators. Yes, of course, there is a financial impact to all this. But what price can be attached to a human life? Unless we change our attitude to this safety-critical system, and give emergency lighting the respect that it deserves – and, within the industry, take a lead on this – all too familiar, tragic events associated with non-compliant commercial premises will continue to occur.

SAFE PASSAGE www.theilp.org.uk

Tragedies such as the Grenfell Tower fire have significantly raised the profile of fire safety, including the role of emergency lighting. Lighting professionals have a key role to play in ensuring building owners select and install highquality, compliant systems and understand the importance of regular maintenance and testing, as Glen Krise explains By Glen Krise

E

mergency lighting is vital to the safety of building occupants, especially in the event of a fire. However, it is also a complex area where a variety of factors need to be considered. The chosen solution must of course comply with industry standards as well as fire safety legislation. While this might sound obvious, it is important to understand what needs to be achieved in terms of design, specification and installation. Emergency lighting is for use in scenarios where the mains power supply is disrupted and therefore standard illumination fails. This can be as a result of a power cut or, as previously stated, in the event of a fire. It should operate automatically and needs to provide sufficient illumination to allow occupants to evacuate, prevent panic and reduce the risk of physical danger from their surroundings. Life safety is a hugely important topic in the built environment sector, with recent

high-profile incidents such as the Grenfell Tower fire significantly raising the profile of fire safety and bringing wider attention to the issue.

MARKET GROWTH

Emergency lighting naturally forms a crucial part of the safety systems of a building and, while the recent focus has been on improving the materials and designs of buildings, it has also highlighted the importance of having reliable escape routes that allow swift and safe evacuation. This has undoubtedly contributed to the growth of the emergency lighting segment of the market. The repercussions of getting fire design wrong are all too clear and, in addition to the obvious safety issues, the reputational damage that can be caused by an injury or, in the worst-case scenario, a fatality can be huge. Furthermore, directors of companies, rather than the organisation itself, are

personally responsible for the safety of premises and their occupants. As highlighted in the previous article, the Regulatory Reform (Fire Safety) Order 2005 came into effect in October 2006 and applies to all non-domestic buildings in England and Wales. It states that the onus is on the ‘responsible person’ to ensure full fire safety. In a workplace, this is the employer or the person who has control of the premises. For this reason, it is common for there to be more than one responsible person and all should be aware of their obligations. This includes carrying out a fire risk assessment, ensuring the maintenance of safety systems and protecting escape routes. In the most serious cases, failure to do so can result in large fines or even custodial sentences. For many building owners, managers and employers it is now no longer simply about complying with regulations but investing fully in the systems that will maximise the safety of building occupants. For emergency lighting, this may be additional emergency light fixtures to provide a level of light above the minimum required standard of illumination to allow an easier and safer evacuation. Along escape routes with normal risks, the minimum light level should be at least one lux. It is also important to remember that if a building is refurbished and the internal layout is changed the emergency lighting must be reassessed and updated to ensure that it still meets the required standards.

THREE MAIN PURPOSES

There are three main purposes of emergency escape lighting within a building: escape route lighting, open area-lighting and high-risk task area lighting.

Escape route lighting, as the name suggests, provides illumination along any route that will be used during an evacuation. It should be designed and installed to illuminate any potential dangers, such changes in floor height and other trip hazards. The lighting should also allow occupants to locate equipment such as fire blankets, extinguishers and first aid kits. Open-area lighting, sometimes referred to as anti-panic lighting, is for spaces larger than 60sq m or where escape routes pass through an open area. The purpose of this is to provide sufficient illumination to prevent alarm or anxiety caused by the sudden darkness and allow occupants to safely locate and reach an escape route. The final aspect is the lighting of highrisk task areas. For parts of a building where a potentially dangerous process is being carried out the emergency lighting should deliver the necessary light to enable shut-down procedures or to make the work in progress safe. There have been a number of documented incidences where a failure of the lighting has caused serious injuries due to the work being carried out. Although not required by the building regulations, an additional type of emergency lighting is standby lighting. This is most often required in areas where the normal activities cannot be interrupted. This could be, for example, in certain areas of hospitals as well as in emergency service facilities. This is different from escape lighting as standby systems are designed to deliver full illumination and the power is most commonly drawn from a back-up generator. There are a range of different options available for emergency escape lighting and the type of system chosen will depend on the characteristics of the building.

Emergency lighting

through the use of maintained or non-maintained luminaires. In a maintained system the selected luminaries will form part of the everyday lighting of the building and simply switch to a battery back-up when the power fails. Unmaintained systems consist of a separate set of fittings that only activate in an emergency. Specifiers also have a choice about the source of the back-up power, as this can be provided by either a battery pack connected to each light or a centralised back-up battery that supplies power to all luminaries on the system. While for larger buildings or those with specific requirements a central battery system may be preferred, for most applications a localised, standalone option can deliver greater cost effectiveness and simplicity. An emergency lighting pack is connected to each required luminaire and monitors the permanent live of the lighting circuit to detect when the power has failed. This then switches to the battery backup contained in the pack to provide power for the required time.

IMPACT OF LED

46

Recent developments in lighting technology have had an impact on emergency lighting systems. For example, the ongoing expansion of LED products means that luminaires now require less energy to run and so illumination can be maintained for longer if required. BS 5266 specifies a minimum duration of one hour for normal emergency escape lighting. However, where the use of the building means evacuation may take longer (for example for sleeping accommodation) this is increased to three hours. Lower energy products allow this requirement to be met without the need for large battery systems, making installation simpler and less obtrusive. Advances in battery technology have also made systems more reliable, in particular the increased use of nickel metal hydride (NiMH) instead of the previous generation nickel cadmium (NiCad) batteries. Because of the importance of emergency lighting systems, specifiers should consider the products carefully. When selecting emergency packs and luminaires it is essential to ensure they are only sourced from reputable suppliers and brands that are members of the Lighting Industry Association (LIA) to guarantee their quality and reliability. Furthermore, it is always recommended to only choose products that have been tested and approved by ICEL – the Industry www.theilp.org.uk

u The shell of Grenfell Tower, now wrapped in polythene. Two years on from the deadly fire, its ramifications for fire safety – and emergency lighting – are still a key area of debate

Committee for Emergency Lighting. This will ensure the product meets all relevant UK and EU standards for emergency lighting. As with all lighting, an emergency system needs to be Electromagnetic Compatibility (EMC) compliant to ensure it does not emit excess levels of EM interference and will continue to function correctly in the presence of other EM producing devices. It is important to note that just because two or more products are individually compliant this does not necessarily mean that it will deliver an EMC-compliant solution when combined. Where possible, specifiers should select products that have been tested together. For example at Megaman, our LED GU10s have been fully tested with our Tempus emergency pack to ensure compliance.

CHANGES TO REGULATIONS

Finally, it is important for lighting professionals to be aware that changes to the IET wiring regulations (BS 7671:2018), which came into effect on 01 January this year, mean that surge protection measures are required where overvoltage could result in serious injury or loss of life. The eighteenth edition of the regulations applies to all new installations designed after 31 December 2018, as well as any additions or alterations to existing installations. As a failure of the emergency lighting systems could have serious consequences for occupant safety, an assessment of the risk should therefore be carried out and

appropriate surge protection measures introduced. This also highlights the importance of ongoing maintenance and testing. As it is likely that the system will only rarely be activated, a rigorous testing procedure will ensure compliance and peace of mind that the lighting will function as intended in the event of an emergency. The LIA recommends the use of automatic testing systems for emergency lighting. This removes the need to manually test each light fixture within a building, which can be time consuming and costly. These units carry out regular tests automatically with no disruption to building occupants. If a failure is detected the maintenance team is alerted by a visual indication at the fitting. In addition to saving time, it also allows faults to be addressed immediately rather than waiting until the next scheduled test to be discovered and rectified. Emergency lighting is a growing area, due in part to the increased awareness of the issues of life safety and the serious consequences if the systems do not perform as intended. Building owners and employers rely on lighting industry professionals to help them select and install high-quality systems that will not only comply with all legislation but will maximise the safety of building occupants.

DRAIN GAIN Upgrading street lighting will often be a key driver for local authorities looking to develop ‘smart’, connected infrastructure. But small-scale projects, even for something as humble as gully and drain management, can all play their part in creating a more connected whole, as one council project is illustrating By Nic Paton

B

ack in March, we wrote about how Slough Borough Council is among a number of innovative UK local authorities trying to put in place a ‘roadmap’ towards smart connectivity, one that involves substantial testing, piloting, collaboration and evaluation (Council building, March 2019, vol 84, no 3). That article highlighted how creating genuinely connected networks can open up the potential for councils to deploy a wide range of smart applications beyond street lighting, although street lighting may be the catalyst. These could be anything from monitoring and reporting of air quality through to noise and road temperature through to waterways, weather conditions, footfall and vehicle counts, among others. www.theilp.org.uk

Slough’s latest innovation is a good example of this, in that it is in very much a hitherto unsung area: gully control and drain management. It is nevertheless a good example of how taking an incremental approach to embedding Internet of Things-enabled (IoT) technologies can, over time, be scaled up. In this case, a small-scale IoT-based gully management trial established in March has grown significantly in just four months.

GULLY SENSORS ROLL-OUT

From this month (June), 20 gully and drain management sensor projects will be rolled out across the borough – with the aim eventually for the system to be borough-wide – in a collaboration between

the council, Mayflower Smart Control and sensor firm InTouch. The InTouch ‘SmartWater’ system uses a data-driven approach to gully management, using predictive analytics and IoT sensors to provide detailed information so that highway operators can proactively tackle road surface flooding. Previously, gully management in the borough (like in many parts of the country) was done through a manual inventory rota check using a paper-based system. From this, instructions were given to each gully team to unblock drains that had been reported to the council. The new system, developed by InTouch in partnership with Lancaster University, Innovate UK and industry partners, will, it is hoped, enable the council to monitor gullies and drains much more effectively, including with the use of real-time live updates, enabling operatives to respond accordingly. In a recent trial, the use of IoT gully sensors and advanced predictive technologies in this way led to gully cleansing savings of 50% and reduced problem gullies from 25% to 5%, according to InTouch. It is also consistent with the UK Roads Liaison Group’s Well-Managed Highway Infrastructure code of practice. Sing-Wai Yu, service manager at Slough Borough Council, said of the scheme: ‘Early results of this trial have been encouraging. We’re now signing up to carry out the next phase of the trial with a view to roll out this technology across our borough. As a local authority, we are always looking to work with companies who offer innovation through technology, combined with significant financial savings.’

Heritage lighting

CAPITAL DESIGNS 50

Working in a bustling city centre can bring with it unique challenges around time and traffic management, continuity, collaboration, and permissions, as two projects in the heart of London by Nottingham civil and electrical engineering firm McCann have highlighted By Nic Paton

B

etween pedestrians, shoppers and constant traffic, Tottenham Court Road in London’s West End is one of the capital’s most bustling thoroughfares. Its tube station has recently undergone a transformation process as part of creating the new station for the Elizabeth Line. And Camden Council’s ‘West End Project’ has been doing much the same above ground. The £35m project is aiming to transform the West End areas around Tottenham Court Road, Gower Street, Bloomsbury Street, Princes Circus and St Giles. Major changes include making Tottenham Court Road and Gower Street/ Bloomsbury Street two-way to traffic, reducing congestion, contributing to improved air quality and simplifying bus routes. The scheme will provide measures to encourage cycling as well as new and regenerated public and green spaces. Pavements are being widened, streets decluttered of unnecessary street www.theilp.org.uk

furniture and new pedestrian crossings put in place. The area’s street lighting has, naturally, been a key part of this, including a project between Nottingham civil and electrical engineering firm McCann and Eurovia Contracting to overhaul and refurbish eight historic lighting columns on Tottenham Court Road.

BUSY THOROUGHFARE

The 100-year-old columns on Tottenham Court Road, located along the length of the street, have been refurbished and reinstated in a new location outside the Grade II* listed buildings currently housing the Heals and Habitat stores. One challenge was the quantity of utilities around the new locations, which meant great care had to be taken with the placement and installation of the heritage columns. The Victorian cast iron columns also had to be removed and renovated, including adding new strengthening bars, prior to being replaced. The renovation work included new globes and energy efficient LEDs and, naturally, the fact they were all listed meant planning consent was required prior to the commencement of any work. Another challenge was the fact that the project was being carried out in such a busy urban location, as McCann area manager Steve Ellis recalls. ‘A lot of the traffic management and permissions were managed by Eurovia, but it was still a challenge at times,’ he says ‘The fact Tottenham Court Road is one of the busiest streets in Britain meant that collaboration and communication between partners – especially between ourselves and our partner Eurovia – was key. That, for me, is the important lesson to take away from working anywhere busy.’

WORK ON THE MALL

McCann has what we might call ‘form’ in working in this sort of challenging environment, having recently completed a high-profile lighting and re-cabling project in The Mall and Constitution Hill. That project, which started back in 2016, required the installation of new ducts and cables to some of the Victorian style columns on each road. At tender stage, the McCann team identified that the initial design would be extremely difficult to achieve and therefore proposed an alternative solution – switching from the original looped configuration to a jointed system as the specified cables were just too large for the available space. In addition, H07RN-F rubber cables had to be used because of the tight bend radii required and re-enterable joints were included at each column, to allow easy access for maintenance. This solution also meant the smaller size cables required for each column could be more easily terminated and there was sufficient capacity for the single cable in the existing entry ducts. In the Mall, the McCann delivery team constructed a new ‘brick pier’ feeder pillar, similar in size and detail to an adjacent existing one. The team then recabled all the lights on the north side, using part of the existing duct. In total, the team re-cabled 23 galleon twinglobed columns. Having to manually dig around trees on Constitution Hill to install around 250m of new ducts, while not disrupting the procession for the changing of the guard and working around 200 members of the world’s media covering the Duke of Edinburgh’s retirement, were just some of the unusual working conditions faced by the McCann team.
