s the UK slowly, fearfully, begins to reopen for business this month, thoughts within the industry will undoubtedly be turning to ‘what next?’. The government may have set out its ‘road map’ for the gradual easing of restrictions, but the reality is we will all probably be feeling our way into the ‘new normal’ of post-pandemic life – and business – for some time to come yet.

Without wanting to be too doom-and-gloom about things, for me it is these next months, once all the government lockdown support measures have tapered down and probably until the end of this year, that may define how the industry comes through this crisis. Will there still be an appetite for investment in infrastructure or urban realm projects, or in architectural or interior work? Will projects that have been postponed come back on to the order books or just be quietly shelved? What will the night-time economy look and feel like, and in fact will there even still be a night-time economy to speak of, especially if the hospitality trade is one of the last sectors to reopen?

Within this, there will be challenges to address around how, just in practical terms, lighting professionals actually go about their business. How will social distancing and infection control work on-site, in offices or on the factory floor, for example? How will ongoing maintenance work be carried out? What will international supply chains, and international markets, look like?

Having said all this, and more optimistically, I am confident the UK lighting sector, robust, innovative and highly regarded as it is, remains well-placed to come through these difficult times. It may not be a pointer to the future, but the way the industry has risen to the occasion in helping the NHS during this crisis – BDP on the Nightingale hospitals as we reported last month and, in this edition, the work INDO Lighting has been doing to create a new respirator for NHS workers – has also been massively to its credit.

The ILP has been part of this, too. Its support has encompassed everything from technical support and a new technical hotline, as we show this edition, through to its more social media-based initiatives designed to support members socially, mentally and emotionally during these anxious times. And as Kimberly Bartlett also highlights this month, supporting mental health and wellbeing will be something the industry needs to address and focus on post-pandemic.

Finally, as Jess Gallacher writes, it was this month a year ago that the ILP revealed its new Lighting Delivery Centre (LDC) regional structure. For me, her review of how LDCs have bedded in and developed over the past 12 months has highlighted the richness, and value, of the support the ILP now offers both locally as well as nationally. This richness is, I feel, also clear in our report in this edition from LDC London’s ‘Smart city – the holy grail?’ CPD event at Southwark Cathedral.

That event, of course, took place pre-lockdown, a time that, at the moment, almost feels like another world. Nevertheless, whatever ‘normality’ emerges over the coming months and however different (and difficult) life and work become, the ILP – nationally, through the LDC network, its education and guidance, through its online channels and through this journal – will continue to work to keep you connected, supported, informed and, hopefully, thriving.

UPDATE YOUR JOURNEY The British Standard for road lighting, BS 5489, has been updated to take account of some of the rapid changes in street lighting technology that we have seen in the past few years. Nick Smith and Peter Harrison assess what has changed and what you need to know

By Nick Smith and Peter Harrison

LIGHTING JOURNAL

T

he British standard for road lighting in the UK is British Standard (BS) 5489: Code of practice for the design of road lighting.

The standard is in two parts. Part 1: Lighting of roads and public amenity areas (issued in 2013) and Part 2: Lighting of tunnels (issued in 2016). The latest version of Part 1 is due to be issued this month (June), although the timings are not completely certain, and so this article is intended to examine the recent history of the standard and what it is likely to include.

The international standard for road lighting is CIE 115: Lighting of Roads for Motor and Pedestrian Traffic. The European Standard is EN 13201, which has been adopted as a British Standard, being identified as BS EN 13201. It comprises four parts: • BS EN 13201-2 Road Lighting. Performance requirements • BS EN 13201-3 Road Lighting. Calculation of performance • BS EN 13201-4 Road Lighting. Methods of measuring lighting performance • BS EN 13201-5 Road Lighting. Energy performance indicators

UPDATED FOR LED

You will notice there is no BS EN 13201-1.

EN 13201 is in fact a technical report, which each of the European member states has as its own standard, which in turn gives guidance as to how the standard will be applied. For the UK it is BS 5489.

In 2013 the dominant light source was of course the high-pressure sodium (SON). Although there were some full spectrum light sources in use, they tended to be installed in amenity areas and architectural installations. How things have changed!

Now, most designers of road lighting schemes won’t have used SON as a light source for a long time; all schemes now seem to be designed using LEDs. LEDs offer many possibilities, but their light distribution is so precise care needs to be taken to avoid issues with glare and uniformity.

Scotopic vision is the term used for your sight at low light levels, where the eye utilises only the rod receptors for sight. These receptors allow us to see light and dark; black and white which is why, in very low light levels, you cannot discern colours.

Photopic vision is the opposite of this, whereby well-lit conditions encourage the cone receptors, responsible for colour and definition, to be used for sight.

BS 5489 2003 acknowledged this phenomenon by allowing a one class lowering of the lighting recommendations where full spectrum light sources had been used. However, this could only be applied for subsidiary roads using the ‘S’ classes.

Subsequent research suggested the reduction of one lighting class was excessive for some ‘white’ light sources; so the 2013 version of BS 5489 addressed this by introducing the concept of Scotopic/Photopic Ratios (S/P ratios).

The S/P ratio calculates the level of brightness perceived by the human eye of light sources by determining the ratio of Scotopic-to-Photopic lumens emitted. The higher the ratio, the better the light source is at stimulating the eye. Therefore, light sources with high S/P ratios at lower wattages (or dimmed) can provide the same perceived light level as higher wattage, low S/P ratio sources.

Again, this phenomenon can only be applied to subsidiary roads using the ‘S’ or ‘P’ lighting classes as there is no evidence this can be applied to traffic routes or conflict areas where higher lighting levels are prescribed.

HOW THE 2020 VERSION DIFFERS

The 2020 version of BS5489 acknowledges that the main light source now in use is LED. So, where the light source has a colour rendering index or Ra of 60 or more there will be no need to apply the S/P ratio for subsidiary roads, as the tables have been published to assume the use of Ra > 60.

However, if light sources with a lower Ra less than 60, then the S/P ratio needs to be applied to increase the lighting level recommendations.

There are thousands of changes in BS5489-1:2020 when compared to the old standard, some significant and some very subtle.

When BS5489 was published in 2013 the European standard was still in draft format; there were a number of areas where the previous European standard 2003 was referenced as well as the proposed standard 2015 as well.

In the 2020 version those references have obviously been updated, and one example of

LIGHTING JOURNAL

Highways lighting this is reference to the S CE and ME classes used in the 2003 standard.

Many of the latest industry documents have been referenced; some 56 were referenced in the final draft. One example is the section on maintenance factors, which has been updated to reference the ILP’s Guidance Note 11/19 Determination of Maintenance Factors, which is available through the ILP’s updated website and the ISO/CIE TS2201:2019 document, which was published last year [1].

Equally, there are parts of the document that have not changed. A good example of this is the section on conflict areas, which is broadly unchanged from the 2013 edition and of course still makes reference to the ILP’s Professional Lighting Guide 02 The Application of Conflict Areas on the Highway [2].

One area that has been added is definitions for absolute and relative photometry as well as a section giving more expanded commentary on the subject too. While BS5489 is a lighting design standard and not a light measurement standard specifically, it was felt that a more concise definition would be beneficial to designers to help them understand the topic better, although neither format is preferred by BS5489.

The significance of what makes a file relative or absolute is not how it is measured.

Although this is important, the measurement is done in accordance with the industry recommended practices, guidance and standards – it is how the file is stored, the intensity table file or i-table.

An absolute photometry file has a ‘-1’ in the flux field, which is the documented industry method of defining that file is absolute. The values stored in the i-tables is the measured output by the photometer and not relative to per thousand lumens of the source flux.

There is also an updated section about ecology in the new standard. In the past few years, we have begun to understand much better the potential impact of exterior lighting on fauna and flora. As we build on new sites, especially green-field sites, the impact on bats, badgers, birds and other forms of ecology can be significant.

Our knowledge of how these species, or receptors, are impacted by artificial light continues to grow and there is an increasing need to ensure these receptors are protected. BS5489 has a number of external references, including one to the ILP’s 2018 guidance note, GN08 Bats and artificial lighting [3].

FOCUS ON GLARE AND LED

One area of concern when using LEDs, and touched upon already, is with regards to glare.

This is an area that has been significantly modified by way of the application and calculation of glare at the design stage.

For example, it has become commonplace for people to utilise the luminous intensity classes or G classes as a way of specifying or deciding the right optic setting or LED product to use.

The latest version of BS5489 now falls into line with the recommendations of EN 13201, suggesting that the function of threshold increment should be calculated for P and C classes as the first choice when (function of ) threshold increment (TI%) cannot be calculated.

If TI% cannot be calculated, like an area design where setting up observers is very complex, the designer can consider the luminous intensity classes as an alternative, but this should not be the only consideration.

Including TI% calculations in an illuminance (P or C) straight roadway calculation is fairly straightforward and would normally be carried out prior to an area design to determine spacing and a suitable optic to use.

In one software, ticking a box will include the TI% results in the quality figures calculated by the software. The TI% is then shown with other quality figures or results. TI is a measure of disability glare expressed as the percentage increase in contrast required between an object and its background for it to be seen equally well with a source of glare present [4]. One question to ask yourself therefore is ‘why would I not want to know something about the lantern I am about to install when it is as simple as ticking a box?’.

Other areas that have been updated within the new standard include a section on control gear that now references LED drivers and a new section on constant light output.

In addition, the reference to semi-cylindrical illuminance has been removed, with reference in its place made to vertical illuminance, following consultation with industry researchers.

New sections have been added on smart cities and electric vehicle charging points, with reference made to i n d u st r y d o c u m e n t s a n d ot h e r recommendations.

LIGHTING SUBSIDIARY ROADS

• The new BS 5489 will be available to purchase from the BSI’s online shop, which can be accessed through https://www.bsigroup.com/en-GB/standards/

One of the most significant changes in the standard is the selection of lighting classes

[1] The ILP’s Guidance Note 11/19 Determination of Maintenance Factors is available to download at www.theilp.org.uk and ISO/CIE TS2201:2019 can be bought from ISO by going to https://www.iso.org/standard/72353.html [2], [3], [4] The ILP’s PLG 02 The Application of Conflict Areas on the Highway; GN08 Bats and artificial lighting; and PLG 03 are all available to download at www.theilp.org.uk. The International Commission on Illumination: International Lighting Vocabulary Termlist is available through the CIE online shop at http://eilv.cie.co.at/

www.theilp.org.uk

for subsidiary roads. It is now assumed that the dominant light source will be white light and the classes available in Annex A assume this to be the case.

The application of S/P ratios previously used to reduce the target illuminance values will no longer be used if the light source has an Ra > 60. In situations where the S/P ratio is < 1, where amber, red or green predominately monochromatic light sources are used, the S/P ratios will be applied in reverse to increase the target luminance because of the poor ability to render colour.

It is not expected this will be carried out extensively, as often in the situations a risk assessment would have already been carried out to determine the change in light source away from a full spectrum source.

It is recommended in the notes that the designer should be familiar with CIE 191 published in 2010 and ILP Professional Lighting Guide 03 L ighting for subsidiary roads when making the choice of lighting class [4].

Finally, some of the other principal drivers for changes to the standard are the consideration of smart cities and how street lighting furniture can be adapted to assist in gathering data.

One example of this is having CMS capable of transmitting the data and sockets or space available to add more receptors over the standard photocell or CMS node. Energy savings, the effect on human health, such as flicker, and recommendations for the control of obtrusive lighting were other key drivers in the update.

As highlighted earlier, BS5489-1:2020 is set to be released this month (June 2020).

It will be supported by updates of industry lighting design software as well as a oneday training course that will be available from the ILP (either physical or digital depending on the ongoing coronavirus pandemic restrictions).

As a final note, BS5489-1:2020 was revised by leading experts in the street lighting field from a range of organisations. These included the ILP, CIBSE, SLL, LIA, Highways England, Department for Transport, Scottish Office, a number of leading lantern manufacturers and industry researchers and experts in their field.

QUALITY CARE COMMISSION Southampton-based INDO Lighting has worked round the clock with academics and its local NHS trust to develop an innovative respirator that, it is hoped, will not only protect NHS staff working with coronavirus patients but also improve the care they can deliver

By Rebecca Hatch

T

hroughout the course of the coronavirus pandemic, one constant has been the need, and demand, for NHS frontline and care home workers to have adequate personal protective equipment (PPE).

A specialist lighting journal like this isn’t the place to get into the political rows that have ensued over this issue. But highlighting how the lighting industry has risen to the occasion and been using its expertise to help resolve PPE supply shortages, as well as responding to the wider coronavirus crisis, www.theilp.org.uk

most definitely is part of our remit.

In last month’s Lighting Journal, we reported on the sterling work that BDP did under intense time pressure to get the first new NHS Nightingale Hospital up and running at London’s ExCeL centre (‘Rising to the challenge’, May 2020, vol 85 no 5).

Another industry name that has responded to the call has been Southampton-based INDO Lighting, in its case joining forces with academics, the NHS and other manufacturing and engineering companies to develop an innovative new Powered

Air-purifying Respirator (PAPR) protective device for NHS frontline staff treating patients with Covid-19.

The hood has been developed by INDO from a prototype created by researchers at the University of Southampton and the NIHR Southampton Biomedical Research Centre, as well as clinicians at University Hospital Southampton.

FABRIC HOOD WITH CLEAN AIR FILTER

Known as the ‘PeRSo’, it is a fabric hood that covers the wearer’s head and has a plastic visor to protect the face. A hose then connects to a High Efficiency Particulate Air (HEPA) filter with a belt-mounted blower system, which delivers clean air, and which can be worn continuously for eight to nine hours and is reusable after appropriate cleaning.

Lighting Journal spoke to INDO managing director Rebecca Hatch on 24 April, coincidentally the one-month anniversary of the UK going into lockdown but also the day the first product was submitted for evaluation that, it is hoped, will enable it be rolled out across the NHS. This is her story.

‘The week before lockdown the call came out from government for support and we, like everybody else within the manufacturing industry probably did, registered our interest. We just thought, “if anything comes of it, we will assess the opportunity”[1].

‘During that week things were really up in the air; customers were starting to review if they could take delivery of products ordered pre-lockdown and the INDO leadership team was considering what was best to ensure the safety and security of our employees. And then literally the next day [INDO chairman] Tom Baynham had a call from a contact he had at Southampton University to say, “look we’re working on this project, we want to use a local manufacturer because we want to work together, are you interested?”. Obviously, we said yes.

‘Lockdown started on the Monday and by the weekend we had several video calls with the university and collected the prototype

JUNE 2020

LIGHTING JOURNAL

The coronavirus crisis to begin the R&D assessment in our factory.

We then started digging into it, the standards that were required and so on, and just said, “we have to do this”.

‘One of the selling points about the PeRSo, at least for NHS staff, is that it has a clear visor rather than, as with conventional respirators, covering the mouth and nose. The nurses have said it is really important to be able to smile at a patient, which you can’t do with a conventional mask solution. The hood covers the entire head and shoulders protecting the user from breathing in contaminated air.

‘The hose goes down your back into the respirator device, which contains a blower unit with a filter, which is providing them with clean air into the hood. It is a bit noisy but, because it is blowing clean air it is actually quite cool to wear, whereas the other masks often get quite hot and uncomfortable. So far, they are really happy with the fit and everything else.’

INITIAL LOCAL ROLLOUT

At the time of our conversation at the end of April, 1,000 units had already been supplied direct to Southampton

WHAT OTHERS HAVE SAID

The hope is the respirator will receive the regulatory approval that will allow it to be used as an alternative to the more conventional FFP3 masks with visors for staff in high-risk clinical areas.

The PeRSo project was initiated by Professor Paul Elkington, a consultant and professor in respiratory medicine at Southampton University, together with Professor Hywel Morgan and colleagues in electronics and computer science and engineering at the university.

Professor Elkington said of the respirator: ‘The HEPA-filtered air removes more than 99.95% of particulate matter and the face mask protects from splashes and accidental touching, so we believe this will significantly reduce the risk of infection further.

‘While the currently-available standard

Hospital, with a further 4,000 on course to be ddelivered. Rebecca takes up the story again. ‘Hospitals of course talk to hospitals and so all the south coast [hospitals] are aware of PeRSo because they are all in the same deanery. Basingstoke, Bournemouth, Portsmouth, Frimley, they’ve all made enquiries already.

‘Because Southampton was involved with the university project and is doing this as part of a controlled rollout, they have been able to take the units before we’ve got the full BS EN certification. We have started to receive enquiries from further afield, too. As soon as we have certification of the products, in line with the OPSS (Office for Product Safety and Standards) Covid-19 standards then we can begin to dispatch more widely’ [2].

LONG HOURS AND TEAM EFFORT

The certification decision was due by the end of last month, and had been sent off the morning we spoke – the conclusion of what had been an incredibly intense month, and team effort, within the business.

Rebecca continues the story. ‘There are three versions of the PeRSo product, going

PPE equipment provides high levels of protection for all staff when used appropriately and in line with infection control guidance, any development which could improve that protection is very welcome,’ he added.

Dr Derek Sandeman, chief medical officer at University Hospital Southampton, said: ‘This is a really exciting development and something we are very proud to be associated with. It highlights the level of expertise and innovation in the city and we have every confidence this will become a very important piece of healthcare equipment globally.

Professor Morgan added: ‘This is an excellent example of industry, universities and hospitals combining their expertise and answering the call to develop healthcare solutions for staff and patients in this crisis.’

from a version that uses more readily-available parts right the way through to PeRSo 1 which is completely INDO-designed and manufactured and where we hope to achieve the full-scale volumes – of up to 10,000 a week – of the estimated demand.

‘We’ve had to develop the design of the product to move to high-volume manufacture of particular parts. It has also been a case of restructuring our production lines and sourcing materials as efficiently as we can.

‘The main challenge at the moment is the logistics and the supply chain, and getting the team in the right configuration to be able to do the appropriate checks to be able to pack everything and get it out of the door as quickly as possible. Time is the most crucial factor. The next phase – assuming certification is agreed – will be repurposing our lines and possibly adding in new additional lines into the factory.

‘We have used our existing supply chain as much as we can; people that we already have a relationship with. For example, for the PCB [printed circuit board] that needs to go into the blower unit, we are using our supplier we work with for our street lighting PCBs who is also in Southampton. That is really nice because, obviously, we already have that relationship and that trust. But we have had to expand that supply chain for things like the hoods, where we wouldn’t normally be involved with those kinds of manufacturers.’

It has been a massive effort, but one that has been intensely satisfying. As Rebecca concludes: ‘It is literally a month today – it was 23 March – that lockdown started; it has been four weeks from nothing to where we are now.

‘The team that has been directly working on this, most of them haven’t had a day off or a proper night’s sleep for the last few weeks.

The university team, too, worked tirelessly to develop the prototype and support us to ensure progress was made.

‘It has been around the clock, especially as we have been dealing with suppliers from overseas for certain parts as well. Everyone has been hugely dedicated and the speed to market is directly linked to the passion of the combined team.

‘Today, when the first units go off to the notified body, I think everyone will relax a bit, but only for a minute! We’ve all agreed that, unless there are any emergencies, we will try and have a day off this weekend!’

SHOWING OUR APPRECIATION O

ne of the brighter spots of the long weeks of lockdown between March and May has been the way the country has come together every Thursday night to ‘clap for carers’, with people coming out on to their streets and balconies to celebrate and thank NHS, essential, social care and care home workers for all they have been doing for the nation during the pandemic.

Local and national landmarks have often been lit up as part of this celebration, in the process creating an opportunity for the lighting industry to use its expertise to show its – and our – appreciation for our healthcare workers.

This has been the case – and to stunning effect – in the work of electrical supplier YESSS Electrical and www.theilp.org.uk

lighting manufacturer, and ILP Premier member, Powerlite Fitzgerald, which combined to bathe one of the cooling towers at Drax Power Station, near Selby in North Yorkshire, in blue light in honour of the NHS. The power station is the UK’s largest, and supplies 5% of the country’s electricity needs, and is one of a portfolio of electricity generation assets owned by Drax across the UK. ‘We have long worked with Drax; we actually lit their turbine hall – 197 LED lights, 25m up; so a very prestigious job for us that is still today saving them a lot of energy,’ recalls Craig Taylor, industrial and controls specialist at YESSS Electrical.

‘I remember I got the call from one of their electrical engineers on the Saturday night while I was at home

watching TV saying they wanted to light one of the cooling towers.

‘The first challenge was the need to light it in blue and the second was how to throw the light that distance. Each cooling tower is 114m tall, 93m in diameter – and you could fit the Statue of Liberty inside each one – so that is a large area to light. The third main challenge was that we needed to get the lights up quickly.

‘Drax needed them in place for the Wednesday to do a trial light-up and then, obviously, to have them ready for the Thursday for the official switch-on and clapping. It was very difficult to do a proper lighting scheme in that timeframe because it is “ how much light is good light?” in these situations,’ Craig tells Lighting Journal .

For the white lights it was quite funny in that various attempts were made to make them bluer, until the correct filter material arrived from Lee Filters,’ says Craig.

‘The lights were installed on the ground about 4m away from the cooling tower, shining up, mounted on a metal framework.

It was mostly just a case of running temporary cables around. Although they are very high wattages, we are only talking small cables to power them nowadays, what with LEDs being low wattage obviously.’

One of the challenges was that you only get about 30% of light out of a blue chip compared to a white chip. The luminaire we chose to use were our Regor LED 11.

This luminaire is based around a modular design that allows bespoke lumen outputs to be easily achieved. We paired a deep blue high output LED with a 60-degree lens to focus the light exactly where it was needed.

As you can see from the pictures the results were incredible. We were able to help the client achieve the desired result whilst keeping energy consumption as low as possible.

Powerlite Fitzgerald and YESSS Electrical have also been working to illuminate the silos at the Scunthorpe steel works, again in appreciation of the NHS and healthcare workers. But more widely, as Craig highlights, like many across the

industry, this work has been just one part of a range of activity to try and provide whatever support it can to businesses and the NHS during the pandemic.

‘Like a lot of companies, we have been helping out with the provision of hand sanitiser. We’ve had to furlough a lot of staff, again like most companies, and we’re classed as semi-key workers, so we’re providing spare parts to factories and doing electronic repairs. We’ve also been very busy sourcing hand sanitiser as well as masks, dispensers and coveralls to businesses so they can carry on working,’ explains Craig.

The coronavirus crisis

YOUR CORONAVIRUS FAQS ANSWERED

W

e all know these are challenging times for those delivering exterior or street lighting maintenance. Although the hope is that by now (June), restrictions will be beginning to ease, key challenges through the lockdown have been how to continue to deliver street lighting maintenance services, electrical testing where certificates expire, and how to deal with routine and reactive maintenance with a reduced workforce.

Here, then, are answers to some of the most common questions we have had from members around these areas during the coronavirus crisis Q. What should we do about street lighting electrical testing where the certificate has or will expire?

A. Carry out a risk assessment on the electrical testing frequency: • Look at how many installations failed last year and in previous years • From that analysis, make an estimate for the likely number of failures this year.

What percentage is it of the overall stock quantity? Do you think it’s high, medium or low?

• If possible, do some analysis of the failures – are there any trends such as age or location (the same housing estate or road)?

• Try to anticipate where failures are likely to occur and how serious they are. Are they minor or more serious?

• Should the likely failures be low and minor, and bearing in mind there may be fewer members of the public out there, then suspending electrical testing for a period will be acceptable.

Recording your decision-making process is essential, for this may need to be substantiated at a later date. This is similar to the deferred MOT testing announced by government.

Should failure rates be medium or high then you could again drill down into the www.theilp.org.uk

During the coronavirus pandemic, the ILP has been keeping members updated on technical issues, and has launched a technical hotline to answers any questions that members may have

failures to identify any pattern to concentrate any available resources.

Again, record the decision-making process in case this is needed later. This may not be an efficient deployment of resources, but under the circumstances it must be considered reasonable endeavours.

Q. Does it matter that street lighting may not come under BS 7671 in future?

A. In the short and medium term, no.

Although street lighting is mentioned as an exemption in the new IEC 60364-1 fundamental principles, it will be months if not years before this affects today’s street lighting engineer.

Q. Should we abandon cyclic street lighting maintenance?

A. Cyclic maintenance could be sacrificed as, if cleaning and lamp changes move from bulk change to burn to extinction, there would be a 12- to 24-month ‘honeymoon period’ when there will be little discernible increase in failures.

Reduced lighting levels due to lamp ageing should not be such an issue unless you are working on a DBFO (Design-Finance-Build-Operate) or PFI (Private Finance Initiative) where testing takes place. In that situation perhaps they could request a suspension during these times.

In future, there would need to be an agreed recovery programme to address the backlog.

Q. How should we approach reactive street lighting maintenance?

A. A similar approach should be applied as above. Determine areas, roads or locations you consider are priorities. Again, you need to be mindful that there should be much less traffic and people out there so the risks should be lessened.

Q. How does this affect DFBO or PFI contracts?

A. Where the work is part of a DBFO or PFI contract then there will be mechanisms for there to be relief from deductions, but there must be dialogue with the client to agree the circumstances and extent of any relief. The contract probably wouldn’t have considered this situation when it was written as the clauses would have been written around war, civil disruption and natural disasters.

Q. What is happening when it comes to issuing works?

A. Many asset management systems allow mobile devices to be used that receive downloaded works instructions, so operatives do not need to visit offices. Where mobile connectivity is not available mobile phones or tablets could be used to transfer works instructions through email.

Why not think about operatives taking their vehicles home and keeping parts in their homes; if they have a garage or shed?

Where lone working or social distancing is not practical then keeping operatives working together as a permanent team could be considered.

Should one of the team acquire the coronavirus there would probably be fewer to self-isolate. Not sharing vehicles would also reduce the risk of spreading any infection.

The coronavirus crisis and mental health

The psychic shock of the coronavirus pandemic has been such that, whatever ‘normality’ ends up looking like, the industry will need to be proactive in supporting mental health and wellbeing, whether for employees who have been ‘furloughed’, working from home or gingerly heading back into the office

By Kimberly Bartlett

P

robably all of us, to a greater or lesser extent, have felt a sense of psychological dislocation during the coronavirus Covid-19 crisis. The sense of fear, anxiety, bereavement (both direct if we’ve tragically lost loved ones or indirect in terms of the ‘loss’ of hopes, dreams, job security or even just of ‘normality’) has been palpable.

In fact, even before the UK went into full lockdown in March, research for the Mental Health Foundation found one in five UK adults (22%) were feeling ‘panicked’ and a third (30%) ‘afraid’ because of the coronavirus pandemic. Almost one in five (18%) admitted to feeling ‘hopeless’ [1].

Even without a terrifying incurable global pandemic to deal with, it has been estimated as many as one in four of us will suffer a mental health problem that is severe enough to warrant some kind of help in our lifetime [2].

Within the workplace, too, the cost of mental ill health – absence because of stress or anxiety – is now estimated to have overtaken that of musculoskeletal complaints, such as back or neck pain [3]. It is not just absence either, many workplace health professionals suggest the cost of ‘presenteeism’ – or struggling into work when you’re unwell and then underperforming or spreading your illness around – is actually greater than that of absence [4].

Depression, anxiety and other ‘invisible’ disabilities such as autoimmune conditions like multiple sclerosis, lupus or fibromyalgia can also lay a person low almost imperceptibly, affecting their work and home life for months or years at a time.

The cost of this is great, not just for mental

health services, the NHS and social care but also for the families, friends and employers of those affected. For some it is too much, and in 2018 tragically there were 6,859 recorded deaths by suicide in the UK alone [5].

And mental ill health affects our industry as much as any other. Indeed, a report last autumn by the inclusion consultancy EqualEngineers warned that engineering faced a mental health ‘emergency’, with one in five engineers saying they had lost a work colleague to suicide and more than a fifth having considered suicide or selfharm themselves. More than a third described their mental health as being just ‘fair’ or ‘poor’ [6].

MANAGING MENTAL ILL HEALTH

For managers and employers knowing how to deal with, manage and, most of all, support someone who is struggling in this way can be challenging, much more so than if, say, they have something physically wrong, such as a bad back or broken limb.

What to do, what to say (or not to say)? Do you encourage them to go off sick, or will that just make things worse? What is the impact going to be on colleagues or, indeed, the fact you still need them to, at some level, do their job?

It is precisely for this reason that a caring, understanding relationship at work can be one important key to long-term sustainability of living with mental health issues. Without the worry of losing your position or the stress of thinking there is just too much work to manage (or that failing to get through it is somehow a ‘weakness’), the mind can reset, and life can get back to normal faster.

The coronavirus crisis and mental health RESTRICTIVE SICK LEAVE POLITICES

For many, another key player when it comes to anxiety and turmoil is an overly restrictive or prescriptive sickness policy.

While some policies are open to interpretation and managerial discretion, some are heavily enforced and tight on requirements.

For example, some policies say an employee can have no more than three bouts of sickness in a 12-month period. This may not seem like a problem until you realise that, often, these policies are based on incidence and not time away.

So, for example, if your lunch makes you ill and you end up needing to take the afternoon off, you will have used one ‘instance’ in just that half day and have only two left for the next 12 months before you risk being written up or disciplined. Yet, someone with a chest infection who has to take three weeks off will still only have used one ‘instance’ and so be in the same position. All of which brings me back to Covid-19 and the potential mental health crisis – as well as economic crisis – that may well follow on from it and which all employers, in lighting as much as elsewhere, will need to be considering and addressing.

OPEN, TRANSPARENT CULTURE

So what is the answer? There is no quick fix to this, no one blanket rule that will work for all. Some things can help – including training around resilience, access to mental health first aid or counselling through an Employee Assistance Programme or even an occupational health professional.

At a more general level, a flexible, open, transparent workplace structure and working to create an environment where people feel able to raise or talk about mental health or ‘coping’ without fear of stigma can also be helpful.

I’d also argue that discretion and understanding at the line management level is the best way to strike the balance between sick leave to reset the health of the sufferer, removal or reduction of presenteeism and, ultimately, an increase in productivity from effective person and sickness management.

Finally, we need to recognise, I feel, the importance of socialisation within the workplace. One thing the weeks of coronavirus lockdown has brought home to many of is how, even if we might grumble about the commute to work, we are, at heart, social animals.

That was why as part of its response to

the pandemic the ILP very quickly put in place a series of social media and online tools and resources to help people stay connected personally and professionally (‘How the ILP has your back’, Lighting Journal May 2020, vol 85 no 5) – and see the panel at the end of this article for more details on these.

Against the backdrop of mass ‘furloughing’ of employees and general job and financial insecurity, we recognised a change in routine (that loss of ‘normality’ again) is difficult for many and, as a social species, being or becoming isolated is not conducive to a healthy mind long term.

Time on your own, when you choose it, is good for the mind. However, having that choice removed works against an evolutionary mechanism that is primed for survival. Isolation can promote depressive episodes even if you’ve not had previous symptoms or may cause inherent illnesses to interact with each other, creating a ‘feedback loop’ [7].

and will help you to connect with each other on an easy footing.

4. Recognise out of sight must not be out of mind. Whether it is a colleague or an employee, if you have people working remotely or at home, it is vital to recognise that, if anything, you need to be communicating more regularly than when you are all staring at your screens in the office, making more of an effort to connect and communicate, and not just by email. So schedule in stuff, pick up the phone, set up that video call.

During the lockdown, we discovered that technology allowed us to be both more connected but also more alone than ever before. Whatever ‘normality’ looks like on the other side of the pandemic, there are important lessons here for our mental health and wellbeing that we can all learn.

TIPS THAT MIGHT HELP

Here, then, are some tips that I’d argue can help to create a more social, more socialised, workplace environment, especially for when you or team members are working remotely or from home, and whether or not that is coronavirus-related.

1. Make time to chat. If in the office you normally have a team cuppa at 11am (and that’s great), add in a ‘virtual one’ for home workers. So it could be an 11.05am (or whatever times works) follow-on video ‘cuppa’ meeting where you just catch up for a drink and a chat that doesn’t have a specific ‘work’ agenda but is just about much-needed visual and auditory stimulation.

2. Communicate good practice. Organisations such as Acas have useful resources around safe and healthy home working [8]. This can include encouraging people to maintain a daily routine that works for them, including getting dressed to switch your mind from home to work mode, taking a break for lunch, building in exercise or just time away from the desk, and properly switching off when the day is done.

3. Dial a friend. Pass on the message that if you’re feeling down it is OK to simulate the office environment by giving a nearby colleague a call and just listening to the sounds of another person working.

Natural conversations will ebb and flow

ENVIRONMENTAL

ASSESSMENT As Britain was whipped by storms and unseasonal weather, it was only appropriate that the ILP-supported LewesLight festival in February took as its theme the impact of human society on the natural world, especially plastic waste, rising sea levels, climate change and global heating

By Graham Festenstein

LIGHTING JOURNAL

The 2020 LewesLight festival

T

he LewesLight festival this year took place at the end of February (from 28 February to 01 March), against a backdrop of extreme weather and the threat of coronavirus growing globally.

Indeed, even just the week before there was a distinct possibility it may not have gone ahead at all. However, storm-battered and slightly depleted, the festival opened on the Friday night to a die-hard audience prepared to weather the wind and rain.

Whilst three of the installations could not go ahead because of the high winds, our stoic visitors were not disappointed as this year saw on display some of the most exciting installations we have been able to deliver in the five-year history of the festival.

As the weekend progressed the weather subsided and our audience increased and by the Sunday the moon was visible and two of the three missing installations had been reinstated.

Being able to see the moon, albeit only briefly, was very important to the festival, as moonlight was one of the primary themes for this year.

Being in the dark skies reserve of the South Downs National Park we are always keen to promote the importance of dark skies, and the festival is as much a festival of dark and shadow as it is a festival of light.

Dark skies, or the lack of them, are also emblematic of the impact human society has upon our natural world and this combined with our second theme – water – which, in turn, generated a narrative about wider environmental issues, including single-use plastic, sea level rise, flooding and climate change.

Starting with these two threads as a brief, our artists and designers came up with some amazing responses, focusing in some cases on single elements, with others managing to combine all of these threads into cohesive works demonstrating the human condition and current dangers to our planet.

MOON, TIDES AND THE SEA

One special moment was viewing Sunny Sribanditmongkol’s installation ‘Tide 2020’ under a starfilled and moonlit sky while listening to its soundtrack, a reading by distinguished poet Grace Nichols of a brand new poem Moon’s Letter to Earth and

watching imagery that explored the moon, the tides and the sea.

Martina Alagna’s piece ‘There is no Planet B’ also created a combined narrative, showing a view of the earth from the moon surrounded by a tide of floating toxic plastic. To provide context, the piece was presented within a nature reserve on the edge of the town centre in a stream that feeds via the River Ouse into the sea just a few miles away.

Jeanne Blissett-Robertson’s installation ‘Running Parallel’ concerned life under the water. A short film shot under the surface of the Pells Pond, a body of water fed by a spring, explored an underwater vista over several months, the time of day changing under different light conditions.

The film was projected on to a screen rising out of the water from the adjacent Pells outdoor swimming pool. This was a tranquil yet engaging piece that commented on the environmental impact we are having on our waterways, wildlife and rising sea levels.

Lee Painter with a team from BDP produced a striking and optimistic work ‘Remembering Our Place’ that incorporated a poem by Christie Amery and embraced the human form. It looked back from a future where the warnings of global climate change had been heeded and steps taken to reverse the impact of global warming.

Eleni Shiarlis’ dynamic and exiting work ‘Lunar Cycle’ investigated the simplicity of connections between the moon and the tides through the lunar phases and generated a bold representation of the reflection of moonlight on water.

SECONDARY SCHOOL PROJECT

Water was also the main theme of installations within and around the Linklater Pavilion. An eco-building designed to withstand flooding, this community resource within the Railway Land Wildlife Reserve is home to education projects, including the Linklater RATS (Raising Awareness of Tides and Sea Levels) a project for secondary school children in collaboration with the Environment Agency.

The festival collaborated with the RATS and the agency to produce a number of pieces. ‘Water Wall’, an immersive dynamic projected installation by artists Maggie Lambert and Emily Lowry was inspired by the issues surrounding the RATS project.

Two installations – ‘Ripples’ and ‘Prepare Act Survive’ – were devised by the RATS themselves, facilitated by LewesLight’s community artist Michelle Dufaur, animator Chris Prewitt and projection specialist Tim Minter.

Some of our artists and designers opted

for purely moon-inspired pieces, the Depot Cinema hosting two of these, both with a cinematic theme. Studio Fractal’s ‘Unknown Ground’ investigated the team behind the Apollo 11 mission, including using original footage.

The second piece was in the form of a workshop based on the film A Trip to the Moon by George Méliès. Gallit and Grimaldi’s workshop participants played with paper, cardboard and light to create beautiful structures and costumes inspired by the film.

In the gardens of Southover Grange House there were two other moon-based works, this time developed through a workshop at a special needs school, Manor Green College in Crawley.

The workshop by Shadow Cabinet Puppetry developed a performance that was turned into a film by community filmmaker Mick Hawksworth. Lighting designer Margareth Sunjoto worked alongside Shadow Cabinet to produce ‘Wonder’ a separate dynamic installation, but also based on the children’s work.

Also within the gardens, Arjun Mistry’s installation ‘Migration’ looked at the impact that celestial cycles have on wildlife and eco-systems. By using reflective material and carefully positioned light sources, Arjun was able to present MC Esher’s famous tessellation of fish and birds in a new light.

Housed within the tower of our 13th century church Trinity South Malling, Kate Chapman’s installation ‘A Space to Drop In’ again explored the relationship between the moon and reflection of moonlight on water. This time, however, Kate was interested in the relationship with the self and the flow of water conveying a positive message for the future.

STUDENT ARTISTS AND DESIGNERS

Other installations included a dynamic, fun interactive piece by digital artist Tim Minter, ‘Light Fish’, a beautiful laser installation ‘Over the Moon …. and Far Away’ by Miranda Davis and Matthew Button and an immersive sound and lightscape set to a poem Salt by Heather Shann with lighting input from Karen Van Creveld.

Last but certainly not least, community artist Nikki Gunson’s wonderful polar bears provided a symbol of the terrible damage the human race has inflicted on the natural world.

As well as our work this year with schoolage children, the festival worked with students from Rose Bruford College’s new undergraduate Architectural Lighting Course, UCL’s Light and Lighting MSc and undergraduate students from Brighton University School of Art, who worked with www.theilp.org.uk

LIGHTING JOURNAL

The 2020 LewesLight festival our artists and designers on development and delivery of their installations. We also provided work experience for technical and event management students from both Rose Bruford College and Guildford School of Acting.

Whilst it was disappointing that we were so plagued by poor weather, it was most pertinent that the unprecedented high winds, high water levels and flooding brought by storms Ciara, Dennis and Jorge impacted on our preparations and the event itself, as they aptly demonstrated the very serious message the festival set out to highlight.

Not only did the storms cause havoc, but working outside on preparations over the weeks leading up to the festival brought home just how unusual and unseasonable the weather has become; animal and bird behaviour along with plant growth were not as you would expect for the time of year.

These observations, along with the messages from the Environment Agency that sea level rise is a very real concern and in only a few decades much of the area of the town we were working in will actually be permanently underwater, reinforced our belief that our concerns about climate change are no exaggeration.

As professionals in art, design, technology and engineering, I think I speak for us all when I say that pooling our skills in a project of this kind and engaging with the wider community is critical to getting this vital message across. We are delighted this year’s festival was able to make a small contribution towards this cause.

LewesLight 2020 was, as always, well supported by the lighting industry. In particular we are grateful to the ILP, Commercial Lighting Systems, iGuzzini, Architainment Lighting, Rosco, Led Linear, Light Projects, Mode Lighting, White Light, EL Wirecraft, Casambi and East Sussex Highways.

Our design practice and production partners for this year were BDP Lighting, Eleni Shiarlis Lighting, Graham Festenstein Lighting Design, Nulty +, Studio 29, Studio Fractal, Russell Beck Studio and Sussex Events.

EMBELLISHMENT

REINVENTED An innovative non-metallic polymer lighting column embellishment kit has been developed as an alternative to traditional cast-iron kits, and is now being rolled out on lighting columns within Essex

By Jonathan Brown

T

here are more than 4,000 lighting columns fitted with traditional castiron embellishments in the county of Essex, all maintained by Essex Highways, a partnership between Ringway Jacobs and Essex County Council.

In early 2019 a lighting column with traditional cast-iron embellishments was involved in a road traffic incident and knocked down. On inspection, it was found to have rusted through beneath the embellishment kit.

This type of corrosion (as most ILP members will undoubtedly be well aware) is called galvanic corrosion. If this column hadn’t been knocked down in the accident, it is possible it would have collapsed anyway because of a lack of structural integrity.

This column was not the first, nor likely to be the last, that was potentially unsafe because of galvanic corrosion, with such degradation over time one of the key drivers behind the ILP’s launch last year of its GN22 ATOMS asset management toolkit.

Columns with and without

embellishments are routinely tested for their structural integrity. But testing columns with traditional cast-iron embellishment kits is problematic.

Often columns with traditional castiron embellishments are marked ‘unable to test’ as the cast iron interferes with the test. The only way to carry out the test properly is it to remove and refit the cast-iron embellishments. In practice, this is not feasible because of time, access and compromised fixings.

This article intends to outline how at TMP Solutions we have been working with Essex Highways to develop a non-metallic polymer lighting column embellishment kit as a safer and more economical alternative to traditional cast-iron kits.

These new polymer embellishments eliminate the structural safety issues caused by galvanic corrosion and can make column testing quicker, safer and more economical, as the embellishments don’t need to be removed during the testing procedure.

A QUICK RECAP ON GALVANIC CORROSION

Galvanic corrosion, also known as bimetallic corrosion, is an electrochemical process whereby one metal corrodes in preference to another metal that it is in contact with through an electrolyte.

The galvanic corrosion occurs when the two dissimilar metals are immersed in a conductive solution and are electrically connected. One metal (the cathode) is protected, while the other (the anode) is corroded.

The rate of attack on the anode is accelerated, compared to the rate when the metal is uncoupled. In the case of lighting columns, the metal that corrodes is the steel column (the anode) when in contact with the cast-iron embellishment (the cathode) and the electrolyte is primarily dog urine or saltwater.

Galvanic corrosion is such a safety concern because it normally happens out of view, behind the cast-iron embellishment kit, yet is weakening the column.

Unfortunately, the most susceptible area of the column is also the most dangerous – the base – as this is often where dog urine and saltwater collects the most.

Street lighting columns can occasionally catastrophically fail because of such corrosion, potentially causing severe injury to people and objects in the vicinity.

UNDERSTANDING OUR POLYMER SOLUTION

Essex Highways had been searching for an alternative to cast-iron embellishments for around four months before contacting us. As a company, we’re generally more synonymous with traffic bollards rather than lighting columns. However, without wanting to blow our trumpet too much, we are known for developing innovative products and bringing them to market. For example, we invented the retro-reflective

rebound traffic bollard. So being asked to develop a non-metallic embellishment kit was certainly something that sparked our interest.

From initial discussions back in September 2019, it took just eight weeks to take the design from idea to prototype.

The new non-metallic polymer embellishment kit was designed to be very similar in appearance to the traditional cast-iron embellishments already installed on across the county.

The embellishment kit is made up of four parts: base, collar, ring and ladder bar.

Producing all these parts could have involved a lot of expensive tooling but, thanks to our talented design team, we arrived at a solution where each part only needs one tool. Each part is made up of two identical pieces that interlock, providing not only strength and security but making installation quick and easy, too.

Designing an embellishment kit that could be left in place during structural testing was another vital part of the brief.

We therefore worked with structural testing companies and listened to their feedback to ensure these new polymer embellishments could indeed be left in situ and not cause any interference.

Installation takes just seconds, with each piece interlocking together. The fixings that hold the pieces together also secure the part to the column. The fixing method is very secure, and the whole kit is resistant to rotation and vandalism. For anyone who is interested, we have videos demonstrating this on our website (www.tmp. solutions).

Sustainability is a crucial consideration in any new product design, and the new embellishment kits are no different. The manufacturing process produces almost no waste, and each embellishment can be removed and reused on

a different column if needed.

The TMP polymer embellishment kit is currently patent pending.

FIRST INSTALLATIONS

Following the development phase, the first 50 sets of the polymer embellishment kits were installed in and around Stockwell Street, part of the so-called ‘Dutch Quarter’, in Colchester, Essex, in January.

I’m very glad to say the installation went without a hitch. The kits arrived ready to fit right out of the box, pre-painted in gloss black and complete with all the necessary fixings.

With this initial phase of the project completed successfully, the second phase of the larger 8m-10m columns was given the green light and installation was due to start last month (May).

I’m also glad to say the feedback so far has been really positive. Indeed, once installed, the TMP non-metallic embellishments look just like their traditional cast-iron counterparts – apart from of course protecting against galvanic corrosion, not needing to be removed when testing for structural integrity, and generally being quicker, safer and cheaper to install and test!

CONTINUOUS

IMPROVEMENT Jess Gallacher looks back at the first year in her role as ILP Engagement and Communications Manager, including overseeing the change from regional to Lighting Delivery Centre local volunteer groups

By Jess Gallacher

O

ne year ago – in June 2019 – the Institution of Lighting Professionals officially made the change from our previous regional group structure to the new system of Lighting Delivery Centres (LDCs).

The fundamental reason behind this reorganisation was to enhance the amount of continuous professional development (CPD) provided to members at a local level.

Sharing knowledge, best practice, and technical information about the best way to provide lighting which benefits society is at the heart of the Institution’s reason for existence.

Following extensive consultation with

LIGHTING JOURNAL

Inside the ILP

members there was a clear message that people wanted more CPD events held in their local area – and they wanted these to provide them with high-quality, relevant and reliable information to help them carry out their lighting roles as effectively as possible.

To that end, the ILP set up an implementation panel with local volunteers and soon ascertained that our volunteers had a great appetite to deliver more CPD to more lighting people than ever before and wanted more support from the staff team to do this.

A FLEXIBLE NETWORK

The questions then were: what would this look like, how should this be organised, how could volunteers be supported to spend their precious time adding value to the Institution using their skills and expert lighting knowledge?

The intention was for the LDCs to become a flexible network of volunteer ILP members across the UK and Ireland, organising local CPD events and networking opportunities. Each LDC would have a main committee and an organising group, supported by ILP staff, to deliver quality educational events.

In implementing these changes, we really wanted to make sure that volunteers weren’t burdened with responsibilities for administrative tasks and were easily able to comply with the requirements of the new GDPR data protection regulations.

Sometimes organising events of any kind can be a series of tasks that don’t in fact need specialist lighting expert knowledge.

We identified areas that could be automated very successfully, freeing time for

people to consider content, style, and engagement with members. We decided it was key to create helpful and user-friendly systems that still gave local volunteers the flexibility to customise each event according to their own needs and requirements.

This led to changes in the roles of ILP staff at Regent House, including the introduction of my own new role as Engagement and Communications Manager.

KEY ‘WINS’ FOR MEMBERS

From the word go, we wanted to ensure members were left in no doubt about how accessible and welcoming LDC events would be. Our mantra became ‘no boundaries, no charge for CPD, no limits’. Let me explain each of these in turn.

• No boundaries. The key here was, ‘everyone is welcome to all ILP events, wherever their location’. We set up a system for ILP members to choose which LDC event invitations and emails they would like to receive by logging into MyILP and choosing their preferred branches within ‘communication preferences’.

• No charge for CPD. Our focus here was, ‘talks run by the LDC branches are free for ILP members’. Fees only apply for social activities, some refreshments and non-member CPD tickets.

We rolled out a very simple procedure where local volunteers fill out a simple spreadsheet, which is then submitted to the ILP treasurers for approval. This enables each LDC to create the right events for their attendees whilst keeping everything recorded and accountable in a consistent way across the whole organisation.

• No limits. For this, it was all about, ‘ILP members can attend as many events as they like’. We introduced a new membership benefit at the same time: each LDC is asked to take a register of attendees and pass it to the membership team at Regent House.

The team then ensures that CPD attendance is recorded on each member’s MyCareerPath account. Each member has their part to play in making sure they have MyCareerPath set up and adding what they have personally learnt at the event.

Adding the event for members has been a very well-received move to help members record their CPD. The extra cost to members for this enhanced service? Absolutely zero. The system is completely free to use.

OFF TO A GREAT START

We launched in June, using the AGM and the Professional Lighting Summit in Newcastle upon Tyne as a platform for members to get together and celebrate all the great work of the previous regions and a bright future as LDCs. Armed with templates, guidance and an amazing array of branding materials, the new teams got underway organising events.

The first LDC event to take place was organised by LDC Birmingham, chaired by Michala Medcalf. This really set the bar high for the new style of ILP local events.

Held at the inspiring venue of the Think Tank, and including a planetarium experience as well as CPD talks, Michala explained, ‘the reason for choosing the planetarium is to show a link between light and the environment and our solar system; how light is created, distributed and measured.’

LDC Birmingham invited lighting professionals with the enticing message, ‘join us in our day of curiosity; a show of the universe lit up in all its glory, quality CPD papers and reflections on the environment’. The turnout was high, and feedback was 100% supportive showing our renewed CPD focus was the right move.

MEMBERSHIP GROWTH

Part of our change to LDCs included the development of a new communications strategy and heightened social media presence.

During September, this meant LDC Bristol managed to reconnect with several former members who had drifted away from the Institution. In fact, seeing how much CPD the ILP could provide www.theilp.org.uk

LIGHTING JOURNAL

Inside the ILP prompted them to rejoin.

Over the course of the year we have found the new LDC system has become a key part of membership growth for the Institution, accounting for 26% of new or rejoining members, as can be seen in figure 1.

A key strength of the ILP has always been its ability to tailor local events to suit the membership.

For example, LDC Durham took the approach of ensuring consistency for local members and arranged a programme of regular evening events from September onwards, in line with what had always been offered by the former region.

This proved especially popular with the local street lighting community. The group also capitalised on nearby lighting CPD with an event exploring the Lumiere Durham light festival, as written up by LDC members for Lighting Journal in February (‘Wear it lightly’, vol 85 no 2).

TRAINING COURSES

Hand in hand with CPD events, the importance of training courses cannot be underestimated.

The new LDC structure has been designed to empower members at a local level and, for example, meant that in November LDC Ireland was able to offer local members the opportunity to attend lighting courses as a collaboration between ILP and Engineers Ireland.

Along with its CPD events, this meant LDC Ireland offered an unprecedented amount of development opportunities for the lighting profession.

JOINED-UP APPROACH

Relationships between each LDC branch, the YLP and the staff team at Rugby have been developed to make sure we share common goals, and work together for the benefit of the members, profession and public.

In fact, LDC branches now provide onethird of all CPD generated by the Institution, as figure 2 shows. Our plan for staff at Rugby to carry out administrative tasks so as to free local volunteers to use their lighting skills and judgement to create relevant events has really paid off, with quality CPD, high attendee figures and wonderful member feedback.

To give a few more examples from around the country, LDC London has been a great example of the different parts of the Institution working in harmony, with members being given a seamless experience of a range of CPD activities from a range of sources.

For instance, over the past year LDC London members have been invited to a university to participate in lighting research, welcomed to learn about lighting www.theilp.org.uk

National Events - Members

As LDC chair David Jones puts it: ‘Thank you all for your assistance in providing the above event. I really liked the extra attention you were able to provide in advertising the event... we are in a better place going forward.’

Another thing worth noting is that all LDC events welcome members and non-members alike.

Of course, we hope to encourage everyone with an interest in lighting to join the Institution and become a member, and this often begins with showcasing what we do and inviting people to experience events for themselves.

LDC Scotland’s programme of events, for example, included a particular focus on welcoming people, explaining more about what the ILP does and how it can help individuals with their careers.

With supporting materials provided from the staff team, this meant non-members were guaranteed a warm welcome.

Figure 3 shows how LDC events have attracted new people to get involved with the Institution on a local basis, and we see this as an important part of the role of LDCs. Even with the coronavirus pandemic sadly cutting short our first year of LDC events, the total number of CPD hours generated was a massive 2,136. This is a phenomenal achievement for the whole Institution to celebrate and of which hard-working LDC members should be immensely proud.

and surfaces at a major architectural fair, nurtured at informal ‘How to be brilliant’ CPD sessions and wowed at Southwark Cathedral to explore lighting and smart cities (and turn overleaf to page 30 for a review of this event).

The range and depth of CPD provided on a regular basis has encouraged a good number of members apply to upgrade their membership.

The team from LDC Manchester, too, has worked hard all year to provide themed CPD days built around specific topics and issues that members have been asking for.

Tempting as it is to challenge ourselves to surpass the 2019-2020 CPD figure, that may not be the case. The focus will of course remain on CPD, the ILP’s reason for existence.

But, as the effects of coronavirus continue to unfold during 2020, the LDCs will begin to explore online events.

We also have it in mind to develop and refine the CPD National Curriculum still further as a result.

Finally, we always need volunteers! So if you have any spare time, please get in touch by emailing me at jess@theilp.org.uk as we’d love you to be part of our achievements.

Most of all, the future includes you – the lighting professional. Contact us and let us know what you need from the LDCs – and that is what we will aim to deliver.

Smart cities and CPD

LDC London held its first CPD event, ‘Smart city – the holy grail?’, at the stunning venue of Southwark Cathedral in February. As we look forward (hopefully) to the resumption of LDC events in the autumn, here is a taste of just some of the CPD and insight that was on offer

By Jess Gallacher

A

fter the past few months of restrictions and social distancing, the very idea of mingling shoulder to shoulder and networking at a Lighting Delivery Centre CPD event feels almost other-worldly. But the hope is, of course, that things will return to ‘normality’ (whatever that will look like) from the autumn and the ILP’s programme of regional and national CPD will resume.

Moreover, as I have highlighted on the previous pages, as the new ILP LDC network has become bedded in and established over the past year, the CPD and events each LDC delivers has gradually built its own momentum, and value, for members across the country.

To that end, as we look forward to the autumn programme, it seems appropriate to revisit one of the final LDC CPD events to happen before the March coronavirus lockdown – LDC London’s ‘Smart city – the holy grail?’ – which took place in February at the stunning location of Southwark Cathedral.

The intention here is, very simply, to give a flavour of the event and to highlight to members the value that can be gained from carving out the time to attend similar CPD and networking events within their local LDC once things do start to return to normal.

The event was sponsored by Zumtobel Group and brought together four speakers, David Orchard from Telensa, Ryan Carroll from Designs for Lighting, Perry Hazell from Southwark Council (and LDC chair), and Dan Hodgson from Zumtobel.

Although nominally themed around smart cities, the afternoon of CPD had a broader remit than simply connected or

smart lighting, with two of the speakers (Ryan and Dan) looking at other areas, which we shall come to shortly.

OPPORTUNITY FOR NETWORKING

The event was also an opportunity for networking, with the CPD presentations being followed by an evening lighting display that showcased the products of Zumtobel brand acdc, illuminating the cathedral’s interior and exterior façade, and the outdoor lighting products of Zumtobel’s Thorn brand.

The first speaker was David Orchard, EMEA sales manager at Telensa, discussing how to move smart cities ‘from buzzword to deployment’. David emphasised the need for lighting professionals to take and drive a holistic, whole-city, perspective when it comes to smart connecting lighting networks.

As he said: ‘The world is changing, we know that; we’ve been hearing that for a number of years now. It is becoming more connected, and smart street lighting is a key part of that. Proving that business case to our customers is critical to help them not only maximise energy savings, but also create a foundation for their future smart city ambitions.

‘Smart lighting controls increasingly make sense from an energy point of view as the price of energy continues to rise.

The central management system or a smart lighting system enables customers to keep managing, controlling and tweaking the dimming profile of their lights to adapt to the changing needs of the city,’ he explained.

‘What does smart street lighting infrastructure provide in the wider smart technology context?’ David then questioned.

‘I think it is a given that, from a location point of view, it is great,’ he answered. ‘You have street lighting columns everywhere around the city, and even in most rural areas too. The streetlight provides a power source for other applications and creates a fixed data point when it comes to the asset management side of things.’

CHALLENGE OF THE BUSINESS CASE

One of the ongoing issues with the rollout (or not) of smart city connectivity has been who leads it or drives it at a municipal level. Who joins it all together (especially if there are multiple initiatives or pilots underway), who pulls the levers to make things happen, who signs off the budget? Within this, how do you build the business case to make this sort of joined-up thinking and investment happen? This was something David recognised in his presentation.

As he said: ‘I think it is a given that the smart city benefits are quite clear, whether it is the financial benefits in reducing costs, whether it is the social benefits of increasing efficiencies, or the more environmental benefits. Instrumenting cities can improve quality of life; that has got to be what smart cities are all about. We are the customers of the city; adding to the quality of life is paramount.

‘The business case for smart cities is less clear, however. Smart city technology is moving and emerging really quickly; the future is uncertain, and things seem to change on a daily basis.

Cities and authorities come up against these questions all the time. What application am I looking for, what network should a city use? Cities have to predict

Smart cities and CPD what their future infrastructure needs to be, yet at the same time often can’t,’ said David.

‘We hear about electric cars and we hear about autonomous vehicles and lots of other things, for example. When is it they’re coming in; how are they going to benefit the city? Cities know what they might go to and they know what their aspirations might be, but they don’t really know. Therefore, smart city infrastructure needs to be flexible and cities must adopt open technology.

But then ‘‘open’’ also means different things to different people.

‘Where we are now, and probably where we’ve been now for a few years, is that there are many single-purpose applications. So, we hear about things such as smart bins or temperature sensors; single-purpose applications and hybrid networks; lots of little things happening: IoT, cellular and radio networks that run street lighting. There are lots of different networks out there,’ David argued.

He then cited the smart city work Telensa has been doing in Harrisburg, the capital city of Pennsylvania in the US. There, the city authorities have deployed Telensa’s PLANet smart street lighting controls as part of a conversion project to LED. A key element of this has been focusing on ways to ‘monetise’ (or make money from) what is otherwise a free wireless network, money that can then be ploughed back into other city-wide benefits. For example, the network has been used to monitor refuse collection to make garbage truck pick-up routes more efficient. ‘They wanted to see whether there were operational savings to be made by not collecting every bin every day, or if that meant they were just over-filling,’ explained David.

Sensors have been used to monitor road temperatures to make predictive models more accurate and save money on activities such as salt spreading during the winter.

Another benefit has been in having the ability to reduce the lighting in industrial areas when traffic is low and then raise it up again as and when needed. ‘It enables you to get the energy savings from dimming the lighting down, but there is the fail-safe that if something were to happen the lighting will go back up again,’ David added.

Air quality monitoring has been a further important focus of the project. ‘By having localised air quality monitors, you can give cities the capability to map out high emissions spots,’ David said. ‘If we know where

air quality problems are and it correlates with where traffic is bad, then we can start to do something about it.’

SMART CITY ‘DIGITAL TWINS’

Many cities, David suggested, were moving toward the concept of having a ‘digital twin’. Or as he explained: ‘Within a smart city environment, it is a virtual model of city IoT devices. So it is about building up a picture in real time of what is happening in a city, and then being able to replicate how a city’s physical assets interact with each other on a virtual platform. So correlating the air quality and traffic data and drawing insight which can be used to create services that improve citizen’s quality of life.’

When it comes to barriers to implementation, one of the main ones remained building the trust and engagement of citizens, especially in the context of data gathering, sharing and ‘ownership’. As David emphasised: ‘Citizens are the customer.

They want, demand, transparency and democratic control of what is happening to what is, ultimately, their data. But there is a lack of resource within local authorities and within companies, and expertise, as to how to achieve this.’

He added: ‘In order to get to a “true” smart city, the industry needs to move to having an array of multi-purpose AI sensors to cover many, many different applications. And platforms that can combine but also protect data as well. If you can bring the cost of the products down and have products that are doing multiple things, and also a platform to deliver the trust infrastructure.’

David concluded by briefly explaining

LIGHTING JOURNAL

Smart cities and CPD Telensa’s ‘Urban Data’ research project.

The project uses the Microsoft ‘Azure’ Cloud platform to create what it has termed as ‘a trust infrastructure for urban data’ or, in other words, a platform that cities can feel confident they can use to collect, use and most of all protect data, with the first deployment having taken place in Cambridge.

Data is collected via multi-sensor ‘pods’ installed on lighting columns, with sensors including video and radar. The data is then combined with other city data, with the ‘trust platform’ enabling cities to apply privacy policies and comply with data regulations as well as making data available to improve services and drive revenues.

Building – and communicating – this sort of trust infrastructure is vital because, as David highlighted, ‘we think the industry is moving towards a mass collection of data on a huge scale’.

As he added in conclusion: ‘So we can start to do really good things with data, rather than create siloed infrastructure with single-purpose applications. If we can drive the cost of those products down and make sense of the data and do the right things around privacy, then I think that smart cities have a good chance of really taking off.’

The next speaker was Ryan Carroll, lighting designer at Designs for Lighting, who spoke on ‘lighting to protect the environment’, in particular the challenges and considerations that need to be taken on board when lighting for sensitive environments.

His talk, which revisited the presentation he gave to the 2019 Professional Lighting Summit in Newcastle upon Tyne, was based around the work the practice had done on lighting the car park at the Dorothy House hospice care in Winsley, near Bradford-on-Avon, which won a Commission for Dark Skies ‘Good Lighting’ award in 2019.

As Ryan put it: ‘Sensitive sites require out-of-the-box thinking to ensure lighting is well implemented whilst fully considering the environmental challenges.

‘Whilst there are applicable British Standards, sometimes it is necessary to challenge these where the prescribed lighting parameters do not fully suit the application to which the proposed lighting is necessary.

‘If you’re involved in the design of a lighting solution for an environmentally sensitive site, there is not a one-size-fits-all rule in terms of the British Standards and guidance. You might find it just doesn’t work for a multitude of reasons. So, it is sometimes necessary to work outside of the comfort zone that the standards provide (providing this approach is risk assessment-based to www.theilp.org.uk

justify your approach) and build it into your strategy. Of course, continuous liaison with the client is key, so you can provide a solution that suits all parties.’

FOCUS ON SOCIAL VALUE

Next to the podium was Perry Hazell, LDC London chair and business manager, Asset Management Services, at Southwark Council, who talked through some of the smart/ connected lighting work the council is undertaking.

This has included rolling out fibre connectivity across its estate of 52,000 properties and piloting LoRaWAN networks across the borough.

As Perry explained: ‘Along with the vision, I think there are three key aspects to consider when implementing a smart city.

These are commercialisation, social value, and efficiencies.

‘If we can help local businesses to grow, then there are obvious social and economic benefit aspects to that. And making Southwark a place our residents can be proud of; that is of course an easy one for us.

‘A lot of people think smart cities is about saving money and driving down cost. But for us it is also about what, actually, can we do to generate income for the council, can we reinvest this in the service? What can we do in regards of utilising our assets better and what does that look like?’

Much like David Orchard, Perry emphasised the need to involve, engage with and bring residents, citizens and local businesses with you when implementing smart city initiatives. As well as the technology you needed to remember – or at the very least not forget about – the importance of social value, he highlighted.

CAREFUL BALANCING ACT

For example, when it came to sensors, there was a careful balancing act that a council needed to think through when it came to the business case/decision-making process, he explained.

‘Everyone is trying to sell you what they want to sell you and make some money out of it. But what can we use that is best in regards to efficiency, social value and commercialisation to help us as a council? And then location, where is it best to go? What is the most lucrative place for the commercialisation side of it and where are the areas of most concern or social value or interest?’ he said.

‘What do the residents want from it?

What do businesses get out of it? How can we make it work for our stakeholders?

Are there things we can do, socially, as a council to help our citizens?’ he highlighted. ‘It’s not just about saving time and money but, for us, also about improv-

WATCH OUT FOR AUTUMN LDC EVENTS AND ACTIVITIES

As members will undoubtedly be aware by now, the coronavirus Covid-19 pandemic has led to all ILP face-to-face events between now and July being either cancelled or postponed, including Professional Lighting Summit, which had been due to take place this month.

A programme of online CPD and social support activity is currently happening in its place but the hope – the intention – is that face-to-face CPD events will resume in the autumn, depending of course on the wider health situation.

To that end, please keep an eye on the Lighting Journal as well as online at www.theilp.org.uk/events

ing productivity,’ Perry added.

The final speaker for the afternoon was Dan Hodgson, lighting applications director at acdc, on ‘outdoor architectural lighting’, especially façade lighting, or, as he questioned: ‘When do you use it, why do you use it, what does it do to a space?’

Dan argued that, to be most effective, outdoor architectural lighting needed to be used ‘to define a space, to define the perimeter of a space; we use it to define history and culture within an urban environment; we use it to define the ground, the experience; we use architectural lighting on public buildings to establish that presence, to define it within its community.’

It always, again, needed to be about people, about people feeling safe within the environments they lived in, he emphasised.

‘It is about linking the interior to the outside. It is about people, it is about presence, about experience, about how it redefines their experience and their cultural heritage. And we use architectural lighting, whether it is on historic buildings or retail façades. We use architectural lighting to reveal the character of a building; to define the scale of the architecture.’

T

he Interreg 2 Seas Smart Lights Concept (SLIC) is a European Unionfunded project that is aiming to develop and test innovative techniques, methods, tools and concepts for energy savings, energy efficiency and renewable energy use in public lighting.

These include a decision-support tool, funding models, business cases, public engagement, and a cross-border knowledge platform.

A workshop on the project was recently held at Portsmouth University to aid decision-makers – policymakers, public lighting authorities and technical experts – in the implementation of smart public lighting technologies.

In particular, we were keen to discuss the selection of optimal actions to take in order to improve the performance of a given public lighting system in different environments. These included addressing a set of multiple conflicting criteria and constraints, such as operating costs, investment costs, CO2 emissions and health and safety.

The SLIC UK workshop was organised by the university of Portsmouth and held on 12 March (so just ahead of the coronavirus lockdown) at the Doubletree by Hilton Hotel in Southampton.

It attracted 29 delegates from industry and academia within the UK and Europe.

The aim of the workshop was to bring together academics, stakeholders, technology decision-makers, and policymakers from across Europe to discuss the potential and relevance of the use of decision-support tools for smart and sustainable public lighting.

The agenda for the day included keynote speakers with expertise in smart and sustainable lighting solutions, a panel and roundtable discussions. The aim of the roundtable discussions was to exchange knowledge between the different participants and to gather insights and inputs for the decision-support tool and to discuss the economic, environmental, and social key performance indicators for the decision-support tool.

Our keynote speakers were: • Professor Djamila Ouelhadj, professor of operational research and analytics at the School of Mathematics and Physics at Portsmouth University and the academic lead. Professor Ouelhadj also chaired the workshop and welcomed the delegates.

• Dr Karen Janssen, SLIC project lead/ manager and a senior researcher at the Centre of Expertise for Sustainable Business at Avans University of Applied Science, the Netherlands.

• David Hollingsworth, senior exterior lighting engineer at Ramboll UK in Southampton.

• Peter Harrison, the ILP’s Technical Director and prior to that director of Harrison Lighting and independent consultant in the exterior lighting industry.

• Richard Webster, street lighting manager for Suffolk Highways.

• Professor Marleen Janssen Groesbeek, professor of sustainable finance and accounting at Avans University of Applied Sciences.

• Dr Hassana Abdullahi, research fellow in applied operational research for the SLIC project at the School of Mathematics and Physics at Portsmouth University.

KEYNOTE PRESENTATIONS

Dr Janssen gave an introduction to the SLIC project, its aims and the partners involved, which we will come to shortly.

She explained that the project involves nine partners: • The University of Portsmouth, UK • Avans University of Applied Sciences, the Netherlands • The municipality of Mechelen, Belgium • The city of Bruges, Belgium • The municipality of Amiens, France • The municipality of Etten-Leur, the Netherlands • The municipality of Veurne, Belgium • Suffolk County Council, UK Dr Janssen also outlined how the research themes of the project focus on four primary areas: funding models and business cases, proven lighting technologies, stakeholder involvement, safety and crime evaluation.

David Hollingsworth explained the concept of a ‘smart city’ to the workshop attendees and what smart lighting can

offer in the context of smart cities.

He highlighted some benefits of smart lighting when integrated with sensors.

These include (but are not limited to): air quality monitoring, noise (car crash or social disturbances) monitoring, and traffic/pedestrian counting.

David also explained how smart cities can benefit from smart lighting using car charging points on lighting columns as well as the potential for using solar power in energy generation.

David advised that, before adding an equipment to an existing column, lighting guidance needs to be consulted. He cited, for example, that this needs to include the ILP’s PLG06 (2014) Guidance on Installation and Maintenance of Seasonal Decorations and Lighting Column Attachments [1].

Peter Harrison in his talk emphasised the benefits and savings obtainable from the implementation of ‘dimming and trimming’ in terms of street lighting.

However, he emphasised that, although lighting standards can be used to apply variable lighting, this requires an engineering approach.

One important note to take away from Peter’s talk was that current lighting standards do not directly take into account the social effects of lighting.

As highlighted above, Suffolk County Council is a pilot partner on the SLIC project. Richard Webster in his presentation therefore provided an update on some of the council’s street lighting innovations.

The council’s aim has been to investigate the potential of additional energy savings that can be achieved by correlating traffic in residential roads to changes on main roads.

Accordingly, the pilot has installed 25 radars to cover 500 lights and one road surface temperature sensor. A further element of the pilot has been the county-wide transition to LED, which in turn has realised energy savings, smart lighting adaptations and the widespread use of data analytics.

The project had successfully obtained a

Smart cities 100% Salix funding, Richard explained.

Professor Janssen Groesbeek is responsible for the development of sustainable finance and business models for the SLIC project. In her presentation she stressed the need to consider smart public lighting as a concept that is not only limited to ‘changing a light bulb’.

Rather, smart public lighting needed to be seen as an all-in-one system that considers the safety and reliability of any chosen technology, money-saving, the involvement of stakeholders, safety and well-being of citizens, and impact of the technology on biodiversity, she argued.

Dr Abdullahi, along with researcher Ramazan Esmeli, presented an overview of the SLIC decision-support tool that has been developed by the University of Portsmouth.

The tool, they explained, had been developed following a series of steps, including the design of the conceptual framework, the design of the user interface, definition of inputs and outputs, and the development of a multi-criteria decision-making model.

The tool is designed to take into account policy and technology decision-makers and the impact and evaluation of different locations, of economic and environmental c o n s i d e r a t i o n s, a n d o f s o c i a l sustainability.

It has been validated by the pilot partners. Feedback from the validation was implemented and a live demonstration of the improved tool was presented. One of the main aims of the workshop therefore was to get feedback from the stakeholders on the design and outputs of the decision-support tool.

Following the keynote presentations, panel and roundtable discussions were led

by Professor Ouelhadj to gather feedback on the design of the decision-support tool.

These concluded that having a tool that supports both a technical and a non-technical user is useful. A consensus was reached that the proposed social indicators of the tool should be implemented using information that can be gathered from the literature and guidelines available in the UK standard. This is because there is a gap within the EU on these standards, and the EU partners could learn from the UK standards.

During the roundtable session, participants were divided into three main groups to discuss the economic, environmental,

and social impacts around the use and implementation of public lighting. The three tables were occupied by the participants of the workshop according to their expertise and topic of interest.

These discussions concluded the following: • Economic impact. An economic model that measures the key performance indicators of operating costs, capital/investment costs, cost savings, and energy savings was agreed to be acceptable to be implemented in the tool.

• Environmental impact. Environmental indicators that were agreed include biodiversity, which can be measured using the rating scale and glare index. However, to include the cost of biodiversity in the decision-support tool, it was highlighted that some monetary value needed to be given to the impact of biodiversity. The monetary value of biodiversity could be based on the idea that, since not all animals are equal in terms of how they are impacted by artificial lighting, the cost value of biodiversity will therefore differ based on the species.

Suggestions were also made that it could be valuable to research the possibility of integrating the decision-support tool with a central database or a Geographic Information System (GIS) so as to use real-time data and location visualisation.

Lifetime CO2 related to production, operation, maintenance and end-oflife (maybe disposal or recycling) were also considered to be interesting environmental indicators for the decision-support tool.

• Social impact. Some of the social indicators agreed were health and safety, user comfort, the impact of road traffic accidents and its relationship to illuminance levels, motorists and pedestrians, crime risk, and the acceptability of and pride in social inclusion. On this latter point, there was discussion around how social inclusion can be promoted by light colour, and how light design can promote a sense of pride.

One conclusion of the discussion was that these social indicators can be measured using information both available in the literature and within the UK lighting standards, as there is again a gap in the EU on these standards.

The EU partners, for example, could learn from UK guidance such as the ILP’s GN01 Guidance Notes for the Reduction of Obtrusive Light adapted from the CIE 150 (2017) Guide on the limitation of the effects of obtrusive light from outdoor lighting installations [2]. The social indicators implemented in the tool following the UK guidelines could also form a basis for the EU partners to develop their own, the roundtable discussion concluded.

SUMMARY

The workshop was very successful in providing insights on the potential of smart lighting and smart lighting expertise, along with looking at developments in this context within the lighting industry in the UK and EU. It presented an excellent opportunity for the academics and stakeholders to present, discuss, network and hear about the exciting innovations taking place in smart and sustainable public lighting and the potential of decision-support tools in aiding decision-making, the selection of public lighting technologies, and the evaluation of their economic, environmental and social impacts.

The discussion and feedback sessions played a significant role in developing a consensus with the partners and the stakeholders around what next steps need to be taken in the improvement of the design of the decision-support tool.

Finally, an important topic discussed during the workshop was the novel multi-criteria method for choosing public lighting technologies, in other words the need to be considering the three sustainability dimensions of economic, environmental and social.

STAND CLEAR A consortium bringing together the lighting and rail industries, academia and the government has been studying how smart lighting technology can be used to improve train station capacity and passenger flow

By Alan Grant and Richard Harris

T

his article looks at the results of a research project that examined how smart technology, and in particular smart lighting, can be used to help our railway network improve station capacity and passenger flow.

The project was run by a consortium led

by DW Windsor, including smart city specialist sister company Urban Control along with the Department for Transport, the govBy Alan Grant and Richard Harris ernment agency InnovateUK, transport operator FirstGroup, the University of Nottingham, and RSSB, the Rail Safety and Standards Board.

THE CHALLENGE

Performance and safety (including the movement of people) at train stations is, naturally, a key concern in rail transport today, especially with the increasing numbers of passengers and often out-dated and cluttered station spaces.

The project, commissioned as part of the government’s 2012 Rail Technical Strategy, believes that improving capacity

and enhancing customer experience will increase passenger flow in stations [1]. The key project requirements were to: • Create intelligent stations that respond to the needs of customers, using dynamic lighting • Use light to get people on and off trains and through the station more quickly and safely • Ensure lighting does not cause glare or visual discomfort for drivers and passengers • Find an alternative to existing wayfinding solutions, including decluttering stations of outdated signage/zoning systems • Modernise the rail industry through the use of current trends, in other words experience lighting that is flexible, controllable, responsive and intuitive • Bring in systems that are instinctive and engaging

THE SOLUTION

The first question that needed to be addressed was: ‘why lighting?’. After all,

JUNE 2020

LIGHTING JOURNAL

Smart cities: ‘intelligent’ stations traditionally printed signage has been used to help commuter flow. However, signs need to be cognitively processed by passengers, which can take a few more precious seconds.

Light on the other hand is much more intuitive and quicker to process.

Lighting can influence behaviour, speed and the movement of people. At the same time, many stations are already upgrading their functional lighting to LED to save energy, so there was an opportunity identified – for LED lighting, with intelligent control functionality added, to deliver added potential.

PROOF OF CONCEPT

The University of Nottingham’s human factors team and Geospatial Institute led a research study to identify the typical movement-related issues an average station faces.

They then conducted an extensive review of lighting research literature, focusing on the reported effects of lighting upon behaviour/mood.

This led to the identification of clear opportunities for using light to influence movement behaviours.

From this, FirstGroup agreed for a proof of concept trial site, at Chippenham Station in Wiltshire.

The project – ‘Accelerating Innovation in Rail 4’ (AIR4) – led by DW Windsor, working with Urban Control, was to develop new wireless, connected lights and sensors for the station controlled through Cloud-based software. The project was part-funded by the Department for Transport and delivered through a competition run by InnovateUK.

THE PROJECT (PLATFORMS)

The aim of the project was to reduce dwell time and improve customer experience and safety. Alongside this, there was a goal to provide intuitive information to customers on where to stand to board the train and improve the flow of passengers off the trains and on the platform.

We used custom designed gobo-projected lighting on the platform to indicate to passengers where to stand to be adjacent to the carriage doors when the trains stopped at the station but not blocking the exit of those disembarking.

This also allowed a freer flow of passengers disembarking. The trial was evaluated by the university with a series of research questions. These were: • Do the lights function as intended?

• Do passengers respond to the lighting/move to stand for the train?

• Do passengers distribute evenly along the platform?

• Do passengers appreciate the lighting intervention? More orderly boarding?

The research was conducted through a combination of observations (both direct and indirect), interviews with customers and staff and by capturing and analysing Wi Fi data.

THE RESULT

Initial results from the study have proved to be extremely encouraging and have provided further insights into customer behaviour.

People did seem to notice the lights (in other words, they looked up, back, and along) and a small proportion of people used the lights to stand in the ‘correct’ place. There were several types of interactions with the lights, which as part of the research were categorised into five main ‘response types’.

1. The participant was positioned in an area from which it would be difficult to see the light and/or they were turned away from the lights.

2. The participant was positioned in an area in which it would be easy to see the lights, but for whatever reason (for example on their phone) they did not notice the lights.

3. The participant noticed the lights and looked up into the canopy, on to the projection or along the platform, but took no further action in response to the light .

4. The participant noticed the light and interacted with it by looking/moving either a body part (for example a foot) or their whole body into and/or out of the projection.

5. The participant was positioned away from the lighting but, once it activated, appeared to move closer/into the light .

THE PROJECT (HANDRAIL AND STAIRWAY)

Here the aim was to encourage efficient bi-directional passenger flows, improve space allocation and regulate walking speeds.

The approach for this element of the project was to install a dynamic lighting version of the DW Windsor Garda handrail system to indicate direction and pace of travel on the stairway; in other words, ‘up’ on the left of the stairs and ‘down’ on the right.

Furthermore, coloured LED lights were placed at the top of the staircase to align people descending; green on the left to encourage people to keep to the left side of

[1] ‘Industry launches new rail technical strategy’, Department for Transport 2012, https://www.gov.uk/government/news/industry-launches-new-railtechnical-strategy

the stairs when descending and red on the right to discourage use of this side. The trial was again evaluated, in this case using the following four research questions: • Do the lights function as intended?

• Do passengers move up and down the appropriate side of the stairway?

• Do the stairways clear quicker during busy times?

• Are there any improvements in passenger experience?

As with the platforms, customers and staff were interviewed, and observers took photos to document results.

THE RESULT

The survey responses indicated that passengers understood the purpose of the lighting. It was found the lights were (perhaps unsurprisingly) more visible during darkness or partial light – ideal for high commuter times – but the movement effect was strongest around dawn.

Several incidents were noted where passengers predominantly used the stairway as directed. Some people were observed moving from one side to the other after observing the lights.

In conclusion, the lights were noticeable and functioned as intended. People responded to the lights and some understood the intended reaction. Others thought they were to inspire use of the handrail, which nevertheless encouraged safer usage and movement.

The feedback from staff was that they found the lights useful as a device to back up their suggestions on how to use the stairway.

The final words we leave to two of our consortium partners. First, Nick Coad, a consultant with rail specialist consultancy Insetting, who is working with Urban Control, says: ‘There was so much interest in our demonstration that is shows that the market is ready for a change.

‘The beauty of these solutions is that they are not limited to rail alone; they can be applied anywhere crowds need to be influenced. The application possibilities are extensive from football stadiums to music concerts.’

And Stuart Parker, property director with FirstGroup, adds: ‘This [research] has been a very exciting project to be involved in. Innovative initiatives of this nature can open the door to a world of possibilities and are setting the standard for future customer experiences.’

Inside the ILP

‘WHATEVER YOU NEED AS AN ILP MEMBER,

I AM HERE FOR YOU’ Stepping into the shoes of Chantal O’Sullivan, who retired from the ILP in March after 38 years, was always going to be a challenge. But new Membership Services Manager Karen Suggett is on a mission to understand the industry, what makes members tick and how the ILP can best offer support and help

I

t was perhaps only appropriate that one of Chantal O’Sullivan’s last acts for the ILP after 38 years of dedicated service as Membership Services Manager was to identify the person who would go on to become her successor.

‘It was Chantal who said to me, “Karen, why don’t you apply?”,’ recalls Karen Suggett with a laugh. ‘I hadn’t thought I could because I was still only in my probation period as Executive Assistant, so it hadn’t even crossed my mind. But I was sitting there thinking it would be a great job to do.’

Karen only joined the ILP last August, coming to the Institution’s Regent House headquarters in Rugby after a decade working for a local HR consultancy as office manager.

‘I had convinced myself I was going to be there until I retired, so it came as a bit of a shock when they made me redundant. I then assumed that at my age I wouldn’t be able to get another job that quickly and so was all prepared to put my feet up and relax over the summer when I spotted the advert,’ she tells Lighting Journal.

STEEP LEARNING CURVE

That was for the Executive Assistant role but, when Chantal announced she intended to retire in March, Karen fitted the bill perfectly.

‘I was working alongside Chantal for three months while she explained the role, www.theilp.org.uk

so there was quite a long handover period.

Having said that, Chantal was with the ILP for nearly four decades and her knowledge and experience was, of course, second to none. So I recognise I am on a steep learning curve.

‘But Chantal always said everything is evolving and changing anyway, so you just have to move with the times. She has given me lots of advice and tips; she was a fount of knowledge.’

Karen is keen to meet, engage with and learn from members, a process she had hoped to kickstart this month at the Professional Lighting Summit until, of course, it was postponed because of the coronavirus pandemic.

However, she urges members nevertheless to pick up the phone to have a chat or drop her an email. ‘I would like to reassure members the whole team at Rugby is doing all we can to support them during these unprecedented times,’ she says of the pandemic.

KEEN ATHLETE

Outside of work, Karen describes herself as something of a ‘gym bunny’. ‘I have the gym bug. I do enjoy exercise. I go running and am a member of the gym,’ she says. ‘When I am not exercising I like to swap my trainers for sandals, as we love exploring different countries and cultures. We’ve done lots of city breaks,

including New York recently.’

Finally, another ‘bug’ she has definitely caught – if that’s not a bad way of putting things these days – is that of light and lighting.

As Karen explains: ‘I’ve sat in on the recent ATOMS online training course and went on the “Fundamentals of Lighting” course. I am finding learning about the industry absolutely fascinating. If somebody had said to me 12 months ago, “ooh look at these new lampposts” – lighting columns, as I now know – I would have thought, “it’s just a lamppost?”. But it’s just so interesting.

‘I never thought I would be the sort of person who would find lighting such an amazing subject, but it is – The Illuminated River in London, for example. And it is everywhere of course – I think lighting is absolutely fascinating.

‘Whatever you need as an ILP member, whatever your request, and whatever support or help you require, especially now in these difficult times, I am here for you, as is all of the team at Rugby. So please get in touch as I’d love to hear from you,’ Karen adds.

Karen can be contacted by email at karen@ theilp.org.uk or, once the rugby office has reopened, by phone through the ILP switchboard on 01788 576492.

Letters to the editor

‘I AGREE WITH RICHARD, BUT FOR ALMOST THE TOTALLY OPPOSITE REASON’

I agree with Richard, but for almost the totally opposite reason. The issue I come across is manufacturers trying to achieve the lowest capital cost scheme by specifying too few luminaires.

This is almost always done by using a Maintenance Factor of 1 or 0.95 when a realistic value might be 0.7. In other words, an independent assessment would show that you would need 40% more luminaires to achieve the correct value of maintained illuminance.

You can imagine the conversations I have had with clients who pay me a fee to tell them that they need to spend an extra 20-40% more on luminaires!

In my opinion, the advantage of using an independent lighting consultant is in the name. The client receives independent, unbiased advice. You might need more or you might need fewer luminaires. And don’t get me started on the quality and accuracy of manufacturers’ technical literature.

Unbiased advice is a legal requirement in financial services and led to the creation of independent financial advisors.

Maybe the ILP should therefore promote the concept of ‘independent lighting advisors’. It could produce leaflets explaining ‘Why use an ILA?’.

Let’s keep the discussion going.

In his article ‘Free delivery?’ in April, Richard Jackson of Designs for Lighting said he hoped to spark debate and discussion. As these letters show, he has done just that WHAT RICHARD JACKSON SAID, AND HOW HE’S RESPONDED

In his article ‘Free delivery?’ (April 2020, vol 85 no 4) Richard Jackson made the case that offering ‘free’ design services to clients was potentially a thin end of a wedge that could lead to the cheapening of lighting design expertise.

In response to Alan and John’s letters shown here, he said: ‘It’s great to see my article has created discussion and I agree with all of the points raised. In response to Alan Tulla’s letter, yes, the inconsistency of information coming from different manufacturers definitely helps to spread confusion, and the independent consultant can assist by ensuring a level playing field.

‘In response to John Bullock, again what you are saying is spot-on. However, in our sector we are often called into action at a later stage when the client is asked to provide a CDM-compliant detailed design rather than the indicative design that he attempted to pass through the planning or highway team at the local authority.

‘In an ideal world the client will employ the independent lighting designer from day one and we will take full responsibility for the whole lighting design process. I don’t think we are there yet for many highway lighting projects, particularly where contractors are being given a more leading role.

‘It seems we have a platform to evolve the discussion and I plan to reach out to Alan and John in the coming weeks to see how we could move this forward with the suggested ideas of independent lighting advisors, a “good design” charter, or a lighting factsheet. It certainly seems like this topic is one the industry wishes to discuss.’

‘RICHARD, I DON’T THINK IT’S THAT SIMPLE’

In response to Richard Jackson’s article, ‘Free Delivery?’, Richard, I don’t think it’s that simple. I understand that there are sectors where the design map works satisfactorily, such as roadway lighting, but it doesn’t translate to the broader lighting design sector.

FOR PRICING

I would never work from the premise that a manufacturer produces ‘indicative lighting design’ in order to provide a cost plan. That’s my job.

It may work when you’re operating within the framework of BS design standards – where there’s not far you can travel outside of established parameters – but for the rest of us the lighting design direction has to be negotiated with the client. And that is a designer’s job – not a manufacturer’s.

FOR PLANNING

I welcome the input of other specialist consultants and engineers in ensuring that the design develops in a practical and realisable form. And I’ll take as much advice from a manufacturer as they are prepared to offer.

But I take responsibility for what’s going on. I expect to sit at the head of the table in those conversations. If something cannot be done, it’s up to me to revisit the brief and advise the client accordingly.

FOR CONSTRUCTION

I have no competency when it comes to on-site works. My interest is in providing oversight to ensure that the design as approved does, indeed, get realised.

I understand my responsibilities under CDM but I also appreciate that other inputs may impact on what I (and the client) want – and design changes may be required even at that late stage in the project. And I have to assume responsibility for that. Again, it’s back to the brief and and more client discussions.

I guess what I’m saying is the designer is the pivot point throughout the process, from initial discussion to completion and handover. So, as far as the design map is concerned, I would shift the design consultant further up the table to sit at the right (or left) hand of the client, and add other professional input as necessary.

Design has to be the ‘voice’ and the ‘soul’ of the client if projects are to be delivered satisfactorily.

WEAVING YOUR NARRATIVE An engineered metal louvre fabric that acts as an innovative directional lighting filter has made a significant difference to projects such as King’s Cross Square at London’s St Pancras

By Joe Reynolds

Louvre technology

H

aving to compromise on your lighting unit choice or the aesthetic of a unit in order to meet regulatory requirements, neutralise glare or to conceal your light source is the sort of compromise that, while sometimes unavoidable, will always pain any self-respecting lighting designer.

Obtrusive external louvres, visors, hoods, films and baffles fitted to control light spill or light pollution are often considered something of a necessary evil. Not only do they interrupt the lighting unit’s design and form, they generally negatively impact on the light output ratio (LOR) and purity (CRI).

But at Smartlouvre, by revisiting and rethinking technology from the 1940s, we have come up with what we feel is an innovative solution that can enable lighting designers to avoid these sorts of painful compromises.

The MicroLouvre (and we’ve trademarked the name) is a simple, engineered metal louvre fabric that has been made to fine tolerances and which is designed to provide control and diffusion of sun, heat, light and air.

It comprises 17 paper-thin durable bronze louvres woven into every inch of the fabric, and the fabric itself is only 1.5mm thick. In fact, we believe it is the world’s thinnest and lightest metal louvre fabric.

FORTIES WEAVING MACHINES

The link to the 1940s is that, to create the product, our technicians went back to the original fabric-weaving machines designed by Dow’s John J Grebe, and spent years modernising them, computerising them and improving the overall weaving efficiency. Ultimately though, the machines, the process and the material first produced back in the 1940s remains the same today.

So, what’s the deal here in terms of lighting and lighting performance? The paper-thin angled louvres act as a directional lighting filter, allowing light to pass through in one direction whilst reducing the visual impact of the light source from the opposite direction, without limiting the LOR or CRI. The louvres are weaved into the fabric at angles of 17deg or 0deg as standard, but the material can be customised to any angle as required.

Because it is so thin and easy to manipulate, the metal fabric can be integrated into new products, or retro-fitted to lighting units. It is usually installed easily under the glass cover without the need for any adjustments to be made to the casing.

King’s Cross Square, St Pancras, London, showing the lighting design by Studio Fractal

The angled louvres mitigate unwanted light trespass, light spill and glare without the need for oversized external fittings that can interrupt the aesthetic of the unit, not to mention adding weight and increasing the size and therefore space required for the unit.

REQUIREMENTS AND REGULATIONS

With its 80% open area, the fabric permits optimum light transfer, ensuring high energy efficiency and full CRI. In photometric testing, carried out with several manufacturers of high-powered lighting units from uplighters to flood lights, there has been no reduction in intensity or output recorded.

The fabric holds an A1/A2-s1.d0 ‘Reaction to Fire’ classification according to BSEN 13501-1:2007+A1:2009 and in tensile performance testing a 1m² panel of fabric, tensioned under load proved a uniaxial stress factor of up to 25kgf/m².

Being lightweight and strong as well as meeting A1/A2 ‘Reaction to Fire’ standards, the fabric can be used in a wide r a n g e o f l i g h t i n g a p p l i c a t i o n s, everything from display lighting, photographic units, spotlights, wall washing, traffic lights, street lighting and heritage lighting.

The fact it is made from bronze also means it is corrosion-resistant, so making suitable for indoor or outdoor use.

Angular selective technology used in production of the fabric can provide anti-glare louvres for either a symmetrical beam or asymmetrical light kick, to suit the application. We can also, natur a l l y, c u s t o m i s e f o r s p e c i f i c requirements.

HOW IT WORKS IN PRACTICE

To give a sense of how the MicroLouvre product can work in practice, and the

sort of difference it can make, the architectural lighting specialists StudioFractal and its partners used the product on a project to create the first new public square in London for 150 years, a functional space with heaps of character at King’s Cross Square, St Pancras.

StudioFractal worked with lighting designer acdc to realise its design for this historic piece of architecture, and we supplied louvred metal fabric to neutralise the glare from the in-ground luminaires.

The result has been a cleverly designed (and expertly hidden) LED lighting scheme where the light grazes up the ground floor of the building to reveal the brickwork. The integrated metal louvred fabric works to hide the light source whilst maintaining an integrated balance of glare control and high lumen transmission.

The varying lengths of the space and the nature of use of the historic building as a public space restricted the designers from using any external fittings to the lights, because of health and safety regulations. The internal application of the metal louvred fabric therefore allowed the luminaires to perform and to meet the desired effect.

As StudioFractal’s Chris Sutherland has explained: ‘The product we used needed to be available in a range of lengths to suit the variation in space available. Being grade listed meant that the luminaire fixings had to be located in existing mortar lines to ensure no damage was done to the façade.’

LIGHTING JOURNAL

Social media round-up

SHARING AND

CARING Even with England now starting to reopen for business, many within lighting remain either locked down at home or furloughed. The ILP has been working hard to keep the industry connected, sharing and learning through social media and online

F

or many, hopefully, Monday afternoons between 3pm and 5pm have been a ‘Hi Light’ of their week. The ILP’s weekly ‘Hi Lights’ online networking events have been important during the weeks of the coronavirus lockdown in keeping the industry connected, inspired and learning.

As Kimberly Bartlett has written back on page 16, the mental and emotional toll of the pandemic in terms of anxiety and worry about the future has been significant, and is something the industry may need to address in the long term.

In its own small way, therefore, a forum such as Hi Lights can be valuable in mitigating mental ill health in anxious times, in showing lighting professionals who are, perhaps, worried about the future that they are not alone.

The events, which run from 3pm to 5pm every Monday afternoon, have provided a space for lighting professionals to bounce ideas off each other, to let people see their lighting solutions, to look for help with projects and specification and, very simply, to provide a place where, if you have time on your hands, you can virtually connect with a bunch of friendly faces.

During May, we even had the team from Nulty+ take over one of our Hi www.theilp.org.uk

Lights sessions, where we discussed everything from art and drawing through to rule-breaking and future-gazing, thinking and sleeping, even movies!

So, don’t be shy, come and join us! During this month, Hi Lights events will run on 01, 08, 15, 22 and 29 June between 3pm and 5pm. All Hi Lights events are free to join, and registration details (through Eventbrite) can be found online at www.theilp.org.uk

CHECK OUT ‘FURLOUGHED FRIENDS’

Don’t forget, too, the ILP’s ‘Furloughed Friends’ LinkedIn group is available to anyone within lighting who is looking for an understanding, professional and kind place for furloughed lighting professionals to share information, CPD, volunteering opportunities and budget-friendly activities.

If you are on furlough in the UK, you are allowed to undergo training and continuous professional development. If you are not furloughed but would like to contribute to the group, please join too.

All are welcome; you don’t have to be a current ILP member to be in this group.

You can find the Furloughed Friends g r o u p a t w w w. l i n k e d i n . c o m / groups/13843909

THE ‘LIGHT MINDED MOVEMENT’

If visual engagement is more your thing, why not join the ‘Light Minded Movement’, the Instagram-based social media initiative being run by the ILP with the IALD, Society of Light and Lighting and Zumtobel Group UK? Each week a theme is set each week and people are encouraged to post pictures relating to it.

The idea is it allows the lighting community an opportunity to communicate through images and to show how they are coping with the changes in their working conditions, life at home, and family; how their days have changed and what they are doing to keep mentally well.

To access the project, open Instagram and search for the Light Minded Movement: w w w. i n s t a g r a m . c o m / light_minded_movement/
