It stands to reason the dark winter months are the prime time to hold light festivals. And this winter, the industry – and the public – has certainly been spoilt for choice. We’ve had events up and down the country including, to name but a few, the Night of Heritage Light, LewesLight, Edinburgh’s ‘Street of Light’ and Lumiere Durham. Last month, as we highlight in this edition, it was London’s turn with the arrival of the first Lumiere London. Artists, it is clear, are increasingly using the expertise of lighting professionals to bring light-based installations and artworks on to our streets and into our public spaces. And the results, as we’ve seen in the past few editions of Lighting Journal are often breath-taking as well as undoubtedly popular with the public. For me, however, the discussion point of an event such as Lumiere London, or indeed any public light festival, is less the displays themselves, however much we may marvel at the skill involved in creating and displaying them. No, for me, it’s the inherent contradiction within them about what we, the public – consumers of light as well as lighting professionals – expect ‘good’ lighting to be. One of the strands running through our focus on architectural lighting in this edition is the importance of understanding when and how not to light as much as when and how to light. As DesignPlusLight’s Sanjit Bahra has argued when speaking about his Southbank Place project in London, good lighting design needs to be, if not exactly invisible, then certainly tertiary; something that complements rather than overpowers or distracts from the ambience of a space. It’s a bit like going to the movies. You might find yourself humming the soundtrack in the shower the next morning or vividly associate it with that film the second you next hear the opening bars. But if you’re constantly noticing it while the movie is running, it’s probably failed in its job. I’m not for a moment claiming this is an earth-shattering insight. This is something any lighting professional will have had drilled into them probably from their very first day at college. Nevertheless, we live in a world where lighting technology and LEDs can do ever more impressive, imaginative and creative things, technology we celebrate in our light festivals and installations. All the more reason, therefore, to remember, and equally celebrate, the inherent tension between feature and function that makes good lighting design such an enthralling occupation. Nic Paton Editor

4 Architectural lighting: Lighting as a Service

PAY AS YOU GO Pay-per-lux or ‘Lighting as a Service’ rental-based models could be a more cost-effective way to integrate ‘smart’ technologies into architectural lighting, as Francis Pearce reports


ver the past decade, the development and adoption of LED lighting has led to significant performance improvements and long-term cost savings for many users. But, according to Iain Macrae, head of global lighting applications management for the Thorn Lighting brand (part of the Zumtobel group) even greater changes are on the way. ‘There will be a step change in what we expect a light to provide. Lighting is likely to become a key application in all senses of the word, delivering not only light but data, Li-Fi functionality and many more things,’ he says. ‘The change in technologies will bring more services closer together. The “Internet of Things” will allow connectivity previously unthinkable. Data is just one option, there will be more, including predictive maintenance, personal settings and so on. ‘As this connectivity joins more technologies, we will see increasing convergence, partnerships and wider acceptance of industry standards and that again will help the specifier – knowing that you can power a light from the Ethernet or connect it to the Internet of Things, and that it will be compatible will be great for suppliers and specifiers,’ he enthuses.

Lighting Journal February 2016

This, of course, is all well and good, and undoubtedly exciting. But what will actually mean in terms of lighting solutions? After all, if it is hard enough to anticipate developments in pure lighting, how much tougher will it be to plan and specify extended or valueadded ‘lighting-plus’ systems linked to the internet or building management systems? LIGHTING AS A SERVICE One answer may be to make it the supplier’s problem, not the specifier’s. Pay-per-lux or subscription-based ‘Lighting as a Service’ (LaaS) models do this by leaving the ownership of the fittings and controls with the vendor, right through to recycling. Under LaaS, users no longer buy lighting, they rent light. This takes lighting out of capital expenditure and makes it an operating cost, which may be reduced as the system gets smarter or more efficient. Zumtobel, for one, has developed a LaaS scheme called NOW! as a way to encourage users to move to LED lighting. Its approach includes taking on project planning, implementation and management, with the installation and

investment costs paid from energy savings over time. An agreement covers disassembly and disposal of the old luminaires plus the installation, commissioning, maintenance and repairs of the new. The benefits of switching to new lighting and using LEDs is felt by both supplier and user: lower running costs, reduced maintenance and cuts in emissions. This can include the use of online energy monitoring to help optimise lighting. This service delivery approach has, up to now, mainly been tried with LED street lighting. But it is making its way into architectural lighting, and even edging towards the home as commercially available Li-Fi becomes more widely available and vendors look for ways to integrate technologies more effectively. Because it focuses on outcomes rather than ownership, LaaS as a business model is potentially disruptive – in the positive sense of being innovative or groundbreaking – even if as a concept it is not entirely revolutionary. Parallels exist in the automobile industry, for example, where some carmakers (and Volkswagen is a good example) have articulated a future

Architectural lighting: Lighting as a Service 5 where they will be selling ‘mobility’ rather than vehicles, and where car clubs will offer a viable alternative both to owning and hiring a vehicle (at least in cities). Bringing the discussion back to lighting, Philips’ global head of sustainability, Henk de Bruin argues there is a need to ‘decouple our material use and energy consumption from economic growth, and to experiment with leasing contracts instead of relying on a “boxed product” business model.’ Or you can also take the example of architect Thomas Rau who, when Philips worked with RAU Architects on the fit-out of its offices in Amsterdam, said: ‘I’m not interested in the product, just the performance. I want to buy light, and nothing else.’ The result in this case was a lighting system that made extensive use of free, natural light and specially adapted LED fittings with a combined daylight sensing and control system to cut energy use – crucially all provided as a service. LaaS, therefore it is clear, need not be restricted to citywide schemes or giant installations such as airports. But does LaaS make lighting more sustainable? ‘In a business sense, yes,’ says Zumtobel’s Iain Macrae. ‘The client can afford to update for a regular and predictable cost; that investment in lighting is a positive thing for a

Because it focuses on outcomes rather than ownership, LaaS as a business model is potentially disruptive – in the positive sense of being innovative or groundbreaking – even if as a concept it is not entirely revolutionary lighting supplier and may encourage more regular upgrades of lighting than before.’ There are, however, limits to the flexibility of LaaS as a model. Iain points out that finance is directly linked to a specific solution and the savings that solution makes for the business. This means that if you change away

from the specified luminaires, controls and services, then the finance is no longer available. However, it does enable organisations to invest in the best available solution rather than just the solution that fits their capital expenditure budget at the time and, as a result he argues, ‘there should be no need to spec break either’. When it comes to environmental sustainability, the jury is also still out, concedes Iain. ‘Certainly these solutions offer significant reduction in energy use but, as an investor, you have to allow the technology to save more energy and resource than it took to manufacture, install, run and recycle,’ he says. LaaS is clearly, then, a conversation point and it does appear to be one direction in which an industry tide may push customers. There does, however, remain a discussion to be had over how this new functionality is used. Do you give individuals more control over their own lighting; what role does data privacy play within LaaS and how do you protect the integrity of combined light and data networks? In theory, though, as Philips chief executive Frans van Houten has argued, ‘just by rethinking designs and processes, many products can be made more eco-friendly, and even be equipped with additional features, at no extra cost.’

6 Architectural lighting: Lighting as a Service

DUTCH COURAGE Last year Amsterdam’s Schiphol Airport opted for a lighting as a service model for its new terminal buildings Last year, Philips Lighting’s Benelux general manager Frank van de Vloed came out with the catchy soundbite: ‘I drink water but I don’t have a reservoir in my basement.’ His comment was made in the context of an agreement between Philips and energy services company Engie (formerly Cofely) under which Schiphol Airport in the Netherlands agreed to pay for the light it used but not the fittings, supplied by Philips. Using a system based on LED lamps should cut the airport’s electricity consumption in half and the specially tailored fixtures are expected to last 75% longer than the previous conventional lighting.

Replacing components rather than whole fixtures also, of course, saves on resources. While Philips will retain ownership of all the equipment, Schiphol Group will lease it for the duration of the contract so that by the end of the contract, fixtures will be re-used elsewhere after upgrading. The Schiphol contract can be traced back to Philips’ decision back in 2013 to adopt what it called a ‘circular economy’ approach to business. This was, it explained at the time, one in which ‘the conventional model of customer ownership of the product is replaced by customer access to the product “paying for performance”.’ The pay-per-lux LaaS lighting model is part and parcel of this as, again in Philips’ words, it ‘allows customers to use the best lighting solution for their needs without owning the hardware’. As Frank van der Vloed explained (and to put his soundbite in its full context): ‘We believe that more and more forward-thinking businesses will move to a Light as a Service model. ‘After all, most of us are used to this kind of model – for example I drink water but I don’t have a reservoir in my basement. Many people are used to pay-as-you-go models. Add to this considerable energy savings from LED technology and the sustainability of the overall system and the proposition is compelling.’


LaaS can reduce energy costs as well as upfront investment, argues Simon Taylor


ighting consumes approximately 20% of all electricity in the world, 30% of electricity in commercial spaces and 40% of electricity in office buildings worldwide. This explains why energy efficiency has become the hot topic when talking about lighting, with more and organisations asking themselves: ‘How can we save more energy, how can we save on carbon emissions, how can we become more sustainable, how can we make financial savings?’.

Lighting Journal February 2016

One way to do this, of course, is through LEDs. LED technology is growing fast and offers many advantages, particularly long life and low energy. However, often with this technology, when the lifetime of the light source has ended, the whole luminaire is discarded. We believe this is the wrong way of thinking and, as such, advocate modularity for sustainability where only the light source needs to be replaced rather than the whole luminaire.

When infrastructure lighting meets highway lighting


Debating the business case for the de-illumination of signs and bollards

8 Architectural lighting: Lighting as a Service LIGHT MANAGEMENT SYSTEMS More effective light management systems can be another answer. By introducing the latest in light management systems, you can better control the lighting and, in turn, enhance the energy saving possibilities still further. Lighting control opens up many possibilities when it comes to maximising the energy savings, and it makes it possible to control when and how much light is needed. In fact, lighting control can reduce energy consumption by up to 80%. For instance, we offer IQ sensors that have a typical payback of one to two years. Sensing with this type of lighting control means no-one needs to remember to switch lights on and off again. A third solution is to rent rather than buy your lighting, a concept gaining in popularity in the market, as Francis Pearce has highlighted on the pages before. To our mind, if you are already making energy and financial savings by combining LED efficient light sources and lighting controls, the logical next step is to use this to finance new lighting systems and installation, including rental or leasing rather than buying. HOW RENTAL SCHEMES WORK We’ve recently launched our own ‘Rent Your Lighting Scheme’. The scheme offers a way to eliminate the investment you would traditionally need to make in equipment while, at the same time,

reducing your organisation’s energy costs from day one. It is an exciting development that has the potential to offer big benefits for UK commerce and industry. The concept is also likely to appeal to business directors and accountants, as the scheme aids cash flow, keeps costs off the balance sheet and takes advantages of various tax benefits. Importantly, it also provides a full performance guarantee over the contract period. We argue it is ideal for all types of applications, including offices, warehouses, industry, retail, hotels, education, and exterior lighting. MONTHLY RENTAL PAYMENTS The way our scheme works is that, once contacted, we visit the company to conduct a survey of existing lighting installation and energy consumption by a technical expert. This is then followed up with the provision of a new lighting plan with a full financial calculation, together with energy saving and CO2 saving documentation. Once the project is agreed, we entirely manage the project from start to finish, including installation, financing and a performance guarantee during the full contract period. Financing arrangements are entirely flexible with monthly rental payments adjusted to projected energy savings making the project cash positive right from the start.

Rental schemes could have applications in many settings, including warehouse lighting

Lighting Journal February 2016

We’ve already completed several lighting projects using this rental scheme. One recent example has been with Whirlpool Corporation, the world’s leading manufacturer of domestic appliances. Aura Light is an accredited Energy Service Company (ESCo) and, as such, we offer energy services and can guarantee energy savings. Accredited ESCos are, in turn, eligible for ‘White Certificates’ or TEEs, which are documents certifying that energy consumption has been reduced. We signed an agreement with Whirlpool Corporation to assist the funding of lighting investment using White Certificates. The project was for the lighting of the Whirlpool production facilities, and our role was to verify the reduced energy consumption obtained through the installations and manage the certification process. To that end, we installed energy saving lighting at Whirlpool’s production facilities and most recently at its Cassinetta refrigerator factory in Italy, where Aura Eco luminaires were fitted along with Aura Eco Saver long life fluorescent lamps. This has led to a reduction its energy consumption by 37% per year and the saving of 103 tonnes of CO2 emissions. Simon Taylor is managing director of Aura Light UK

cheduled for completion in 2019, Southbank Place is a mixed-use riverside development being led by the Canary Wharf Group and Qatari Diar Real Estate Investment Company, and situated just down from Waterloo Station, opposite the London Eye. One element that has been completed however, and which incorporates a distinctly eye-catching bespoke architectural lighting scheme, is the development’s Grade II* listed marketing suite in County Hall, in the former offices of the Greater London Council. The scheme was designed by lighting design firm DesignPlusLight (DPL) in conjunction with interior designer Goddard Littlefair to create a high-end, luxury lighting scheme to seamlessly connect the entrance reception, meeting rooms, display pods and finally into the sample suites. ‘Our whole design ethos is to create layers of light that collectively enhance the perception of space and communicate an instant feel of exclusivity. Good architectural lighting should always complement, but never take precedence over the interior design,’ explains DesignPlusLight director Sanjit Bahra. ‘It is important to understand what not to light as much as what to light. Good lighting design should enhance an interior and not detract. It’s a fine balance to achieve. ‘And this approach was essential in a space like Southbank Place because of the very sensitive heritage aspect of it. There were significant physical restraints, for example we were not allowed to chase in new wiring. But it was also important to be sympathetic to the architecture and history of Southbank Place,’ he adds. LIGHTING INTEGRATED INTO THE JOINERY The project uses an architectural lighting control system to ensure that all the lighting elements are carefully balanced to create mood settings. Because of the chasing issue, DPL proposed a wireless control system by Rako Lighting that enabled the existing wiring to be used and expanded upon to create multiple circuits within each room. DPL and Goddard Littlefair then worked closely to integrate the lighting into the joinery pieces to bring layers of light into each space. Within the entrance reception, existing ceiling points were reused and the fluorescent bulkheads replaced with bespoke decorative chandeliers to give sparkle and glamour to the space. A new reception desk was designed with vertical lines of LED light carefully detailed within the metal folds, offering a glimpse of the structure within. Discrete surface spotlights concealed within the ceiling coffers provide a focus on to the stone fireplace and clock. The window treatments of sheers and curtains were highlighted with a halo of light emanating from the head of the pelmet, softly lighting the display plinths below. ILLUMINATED PANELS A bespoke 6m crystal chandelier from Preciosa Lighting was designed and commissioned by Goddard Littlefair and hung in the stairwell to emphatically draw the visitor up towards the first floor. A total of 16 interlinking rings of light, supported from five storeys above, cascade down the central stairwell. The existing fluorescent landing bulkheads were covered with parchment shades to soften their appearance and to provide a warm domestic-like light. To create a sense of arrival on the first floor landing, DPL up-lit the arch reveal above the door header and illuminated specialist eglomisée panels either side. These reflect the light from the chandelier to provide further sparkle.

Architectural lighting: projects 13 In the reception room, a stunning chandelier anchors the visual attention to the centre while custom-designed cabinet pieces frame the four corners of the room. These serve both as display pieces but also house the heating and air-conditioning mechanics required for the space. DPL integrated a flush line of light to frame each cabinet and individual display recesses were lit with under-shelf lights. LED up-lights were concealed in the top of the cabinets to provide reflected light into the space. Subsequently only a few surface spots were required to light key artwork pieces. The boardroom features a custom-created black raindrop chandelier by Tom Dixon. The light hangs down from the ceiling in tandem with the bespoke joinery pieces. The showroom features two closing rooms. Both feature custom-designed chandeliers with surface spotlights concealed adjacent to the chandelier rose to light the fireplace and artwork. Smaller cabinets are designed as drinks cabinets, again lit with concealed LED strip-lights to provide a warm reflected light into the space. The second closing room, which once served as the office of Ken Livingstone when he led the GLC, has a high bay window that offers a magnificent aspect of Big Ben and is softly lit with LED strip-lights concealed behind the pelmet. Plug-in up-lights illuminate the fireplace surround whilst the occasional surface spotlight lights key artwork pieces. An integrated corridor links the u-shaped 1,207sq m suite rooms. The original timber panelling within the corridor was removed and restored, giving DPL the opportunity to bring cables up the walls without damaging the fabric of the building. LED strip-lights were then concealed to the top of the pilasters so as to up-light the vaulted arches and create a sense of rhythm along each corridor. At each junction, mini LED spotlights were concealed behind custom-made plaster mouldings to highlight the cross vaults and punctuate the end of each corridor. The existing fluorescent pendants that were once the sole form of lighting within the space were replaced with decorative glass and parchment lanterns. These could not

be dimmed, as they were the emergency lights to the space, so DPL recommended low energy LED candle lamps that enhance the room with a soft glow. Finally, there are a series of exhibition rooms overlooking the Thames, where potential buyers can view the individual elements of the development with scale models and information panels. SENSE OF CONTINUITY The lighting approach was kept consistent to ensure a sense of continuity across the exhibition space. The juxtaposition of the original listed panelling and the contemporary display pod was playfully enhanced with coloured lighting, which enhances the perception of an intimate room within a room. The free-standing timber beamed structure allowed for the concealment of LED spotlights to illuminate the display pieces. Each room had a Creston control screen that allowed the mood of the room to be altered at the touch of a button (commissioned by Fisher Productions). ‘There are so many interesting things you can do with lighting these days. The advent of LED technology has opened up a realm of exciting possibilities enabling you to design things that were difficult to do in the past,’ explains DPL’s Sanjit Bahra. ‘There is always a danger that lighting becomes the most apparent thing for all the wrong reasons (ie as a glare source or poorly executed design). ‘Whilst it’s perfectly fine to immediately notice a bespoke decorative light fitting, a dynamic installation or something of that ilk, however in architectural terms, my view is that good lighting design needs to reveal the space in interesting ways that complement the interior or the exterior. ‘To my mind, the realisation of good lighting design really needs to be secondary or even tertiary. You should walk into a space and go “wow this is amazing architecture or interior design”. You should then be looking at the interesting details within the space. And hopefully then, after that, there is a realisation of the enhanced ambience or atmosphere created by lighting,’ Sanjit adds.

SQUARING UP Five feature lighting columns are at the heart of new public space transforming Sunderland city centre. Lighting Journal took a look

Lighting Journal February 2016

Architectural lighting: projects 17


ugust bank holiday Monday last year was something of a red-letter day for the citizens of Sunderland. This was because it marked the formal opening of Keel Square, the new £3 million public square that is at the heart of an ongoing multi-million pound city centrewide regeneration strategy. The square is home to new fountains, ‘friendship benches’ highlighting Sunderland’s international links and two pieces of public art that celebrate the city’s proud shipbuilding heritage. The ‘Keel Line’ is a strip of engraved granite running through the square and ‘Propellers of the City’ is a 3.5m-high interactive sculpture (see cover). The development of the square has been led by Sunderland City Council’s in-house landscape architecture team, with the whole project winning in the Public

Space category of last year’s Northern Design awards. From the off, lighting was envisaged as being central to the regeneration project, as senior landscape architect James Gordon recalls: ‘In consultation with our PFI lighting partner, Aurora/Balfour Beatty Living Spaces, we developed a strong vision to provide striking statements whilst providing flexibility to cater for different events, themes or moods. ‘All elements were to work together, from architectural lighting to feature lighting such as gobo projections and water feature lighting, to create different effects through the seasons and for special events. However, the principal sculptural pieces were to be the bespoke lighting columns, complemented by various other focal and sculptural pieces,’ he adds. g

The building’s grand clock tower is highlighted from a floodlight on an adjacent column, with additional floodlighting of its north and south elevations from further floodlights on a hidden platform.


The design team turned to Philips Lighting to design and install five bespoke feature lighting columns, which would provide day-to-day illumination as well as have the potential to be used for special occasion lighting. These slender, steel and timber-clad structures incorporate CCTV at their tops and metal sculptural elements at their bases, the latter designed to deter potential vandals. The metal elements have also been designed to look like the riveted sheet metal of ships, again to highlight Sunderland’s maritime heritage. UNIFORM LIGHT DISTRIBUTION The feature columns have been fitted with Philips UrbanScene luminaires. One challenge, given the fact there were only five lighting points, was to achieve uniform light distribution across the square, and this required precise positioning and orientation of the luminaires. The columns are also fitted with a number of UrbanScene gobo projectors using a variety of templates to project images on to the surrounding buildings and paving. Provision has been made for fitting temporary bars to the columns to support additional lighting for special occasions. The council was, naturally, keen to ensure the square could become a community focal point at Christmas. To that end, an additional feature column has been created, designed in keeping with the feature columns, which can be erected when needed. When erected this will create a 25m by 18m canopy of light, containing around 25,000 LED lights as the main element of the Christmas lighting within the square. The square is enclosed to the west by a Grade II listed magistrates’ court and the project sought to anchor this structure into the new space, again

‘DANCING’ WATER TABLE The architectural details of the building’s facades are picked out by a combination of Philips Graze Powercore, ColorReach and DecoScene RGB LED luminaires within ground-mounted enclosures, as column attachments, and roof-mounted units. The square also features a ‘dancing’ water table, again illuminated by colour-changing LED fittings. The colour-changing lighting, which was commissioned by LITE Ltd, is synchronised from a central point through a Pharos DMX control system using a DMX-DALI interface to the luminaires. This has been used to create sequenced programmes that provide flexible colour schemes and can be changed to suit requirements. The Pharos controller is located in a new pump house constructed for the water fountains. This means when the lighting is being changed manually the effects are immediately visible from the pump house. On the north side of the square a new dual carriageway has been created, running parallel with the river. Both road and pavement lighting for this have been provided by Philips Luma LED lanterns mounted on 59 bespoke single and twin arm conical tapered columns. These incorporate a removable bracket arm fixing at key locations to allow for flexible advertising and wayfinding banners. Some of the columns also carry CCTV cameras.

t’s the constant tension faced by any heritage site or historic building owner: how to balance visitor enjoyment (and the vital money it brings in) with the preservation of paintings, textiles and furniture that are vulnerable to light fading and ageing. Pioneering research by Professor John Mardaljevic, professor of building daylight modelling at Loughborough University’s School of Civil and Building Engineering, has been helping the National Trust to square just this circle. By using a technique called ‘high dynamic range’ imaging (HDR),

essentially a combination of camerabased modelling and photometry, Professor Mardaljevic has been able to measure where the natural light falls at different points throughout the day over several months in the Smoking Room at the trust’s historic Ickworth House, near Bury St Edmunds in Suffolk. As Professor Mardaljevic explains: ‘Light is the way we first encounter the world, the wider world beyond our immediate touch. Whilst most vision is concerned with the light that is coming off services, my work has been concerned more often with the light that

is falling on to services. ‘My first postgraduate research was modelling the light from very distant galaxies. So when I began working in buildings, it was a great surprise to discover that daylight in buildings was modelled using a very simplistic notion. So I began work on what became known eventually as climatebased daylight modelling, and that is something that has underpinned my work for the past 20 years. ‘In any heritage building, any heritage space, the light will vary enormously across the walls depending

Architectural lighting: measuring daylight 21 on the arrangement of windows and time of day, and so forth. If illumination is measured at all in these spaces, it will be at just one, possibly two, points. Our techniques show the illumination across all the surfaces of interest to the space; so is a comprehensive evaluation of the illumination conditions over long periods, over months or even years,’ he adds. Dynamic range imaging is where a camera is linked to a computer, which in turn controls the sequence of exposures. ‘Every ten minutes a sequence of exposures takes place, and from that the computer creates a cumulative luminance image – this is the high dynamic range picture. ‘And from that we can get a physical measure of illumination exposure; everything that the camera sees with its wide angle,’ says Professor Mardaljevic. DAYLIGHT MANAGEMENT By combining the HDR measurement technique with climate-based daylight modelling, Professor Mardaljevic is able to predict how the long-term daylight exposure can change when, for example, opening hours are increased, especially at different times of the year. ‘Often, for example, it is clear the most risk is when the rooms are opened in the winter because of the low angle The smoking room: measuring illumination exposure

of the sun,’ he explains. ‘High dynamic range imaging is a technique that could be applied to other museums or heritage buildings.’ His work has also led the National Trust to look into the feasibility of revising the daylight management guide for its historic houses, including things such as the scheduling of the use of shutters/blinds in each of the rooms. As Dr Nigel Blades, preventive conservation adviser at the National Trust, explains: ‘The problem we’re facing is how to balance getting enough light so that people can see and enjoy things, and that we’re not damaging or fading things at such a rate that a lot of things will be lost to us completely in maybe a few years or decades’ time. ‘John’s research has been really helpful for us to understand better the fall of daylight in those rooms and how we can learn to manage the shutters and blinds, and keep the daylight out when we don’t need it and provide as much as possible when the visitors are in so they can enjoy the collection. ‘Based on the research, we will finetune our use of daylight to minimise the rate of change in light-sensitive objects, while providing sufficient daylight for visitors to enjoy our collections,’ he adds.

LONDON CALLING Winter is the season for light festivals and last month it was London’s turn, with the capital witnessing its first Lumiere London


t was London’s turn to get the ‘Lumiere’ treatment last month, following hard on the footsteps of Lumiere Durham in November. Some 30 light-based artworks, installations and exhibits were concentrated in four central London locations: King’s Cross; Mayfair and Grosvenor Square; Piccadilly, Regent Street, Leicester Square and St James’s; and Trafalgar Square and Westminster. The free event was developed by creative producers Artichoke and supported by London mayor Boris Johnson, and ran across four days from 14-17 January. Although by no means the first light festival in the capital, it was first specifically Lumiere-branded event and attracted more than one million people, said Artichoke. Visitors were encouraged to explore what was described by the organisers as a ‘dazzling night-time gallery’ on foot, so as to allow them to discover parts of the capital for the first time or simply see familiar sights in a new light. To that end, a number of set walking routes were created between many of the exhibits.

At Westminster Abbey, French digital artist Patrice Warrener used his ‘chromolithe’ technique to ‘paint’ the Abbey’s West Gate in riot of colour. LIGHT SCULPTURES ‘The Light of the Spirit’ highlighted the statues above the Great West Door as well as parts of the two western towers built by Sir Christopher Wren and Nicholas Hawksmoor. In Piccadilly, Lumineoles light sculptures ‘danced’ with the elements, while on the façade of the BAFTA building (195 Piccadilly) stars and directors of British screen and TV appeared as part of a dynamic technicolour artwork by Newcastle-based studio NOVAK. At King’s Cross, visitors were able to explore the area, its

buildings and spaces through 11 installations and projected artworks, including the ‘Circus of Light’, a magical animation across the breadth of the re-purposed Granary Building commissioned for the festival from Portuguese studio Ocubo. There was also ‘Diver’ by Ron Haselden, a 17-metre light sculpture at the King’s Cross Swimming Pond Club. Mayor Boris Johnson said the event had ‘brought a wonderful burst of imagination, colour and creativity to our city’s streets in the middle of cold, dark January.’ He added: ‘We have been astounded by the crowds, which exceeded all our expectations and brought a boost to the West End and King’s Cross and are delighted by the response, not just from Londoners, but visitors from around the world.’

Hard-to-predict variables such as access, climate and obstructions can make on-site exterior lighting lumen maintenance and testing a real challenge. Gareth John assesses the role laboratory-based testing could play

Lighting Journal February 2016

Exterior lighting and lumen maintenance


run a commercial photometric laboratory, fully equipped and state of the art – those of you who have experienced my sales pitch before have no doubt heard this part, but bear with me, it does get interesting! My customers expect me to be fluent with all the various standards and technologies and up to the minute on what’s going on in the lighting business. I have to be pretty light on my feet, reacting to new test and measurement standards in the lighting industry and generally staying up to date with what’s going in ‘the biz’. All the same, I occasionally get a phone call that catches me slightly unawares and requires me to think fast. Such a call happened a couple of summers ago when somebody from one of the big names in lighting called me up and asked me about ‘TR28 and lumen maintenance testing’. Lumen maintenance testing was an easy one. Measuring changes in light output as a function of time is a standard service we offer. But what TR28 dealt with and its relevance to lumen measurement in this context was a new one on me. I’m an optics guy, not a street lighting guy per se, so this particular standard had passed me by. Essentially, the caller wanted to bypass this standard and do lab-based testing instead. Although this particular enquiry eventually didn’t come to anything, the conversation left me curious about exterior lighting lumen maintenance and where laboratory testing fits into it. So, the following is a summary of what I’ve learned on the subject – how it works, why it’s carried out and where I think it should go in the future.

LUMEN MAINTENANCE – WHAT IT IS, AND WHY YOU NEED TO DO IT If you install exterior lighting, eventually it’s not going to be as bright as it used to be. The luminaires are going to accumulate dirt, the lamps themselves will become less bright as they get older and eventually the lamps will burn out. However, anyone who installs lighting does so on the basis it will continue to deliver the required light on the roadway year after year. The industry therefore needed a metric that could predict this depreciation year on year and let us know when the illuminance fell below tolerable levels and therefore, when you had to re-lamp or clean the luminaires. The Maintenance Factor (MF) was invented to assess this. The International Commission on Illumination defines MF as the: ‘Ratio of the average luminance/illuminance on the working plane after a certain period of use of a lighting installation to the average luminance/illuminance obtained under the same conditions for the installation considered conventionally as new.’ (CIE 17.4, International Lighting Vocabulary, 1987). MF is a number between 1 and 0, calculated as shown below: MF = LLMF x LSF x LMF Where LLMF = the lamp lumen maintenance factor that is used to correct for the depreciation in lamp lumens due to the time spent burning; LSF = the lamp survival factor: this takes into account the probability of lamps surviving for a given time; LMF = the luminaire maintenance factor this describes light decline due to build-up of dirt on the face of the luminaire. LLMF and LSF are both dependent upon the type of lamp being used. LMF is dependent upon local pollution levels and the IP rating of the luminaire enclosure. Over the years the industry has compiled tables that give values for each term in the above equation as a function of lamp type, environmental zone and IP rating of the fixture. There will be discussions between the contractor and the end user about how low each value should become before the luminaires are cleaned and the lamps replaced, and hence this leads to agreement on cleaning intervals and re-lamping intervals. I’ve heard 0.8 or 0.9 quoted as typical values but some readers may have different expectations. All of this is based on data we have about how luminaires behave


in known conditions but there are certain variables we can’t necessarily predict. To give a couple of examples, the temperature can’t be precisely controlled and this will have an effect on lumen maintenance. One also has to consider that the control gear may not be appropriate for the light source and this may lead to lumen depreciation. However, as metrics go, this is a pretty good one, given it’s based on sensible physical assumptions and it’s easy to understand. The questions therefore are: how do we use this data to predict how lighting schemes will maintain illuminance levels, and how do we test to ensure they are actually doing so? LUMEN MAINTENANCE MEASUREMENT – PREDICTIONS AND REALITY When we carry out measurements of lumen maintenance, we should compare against a predicted base line. Generally, people use lighting software in order to assess what the lighting levels will be and how well they’re expected to be maintained. Part three of the Road Lighting Standard 13201 Calculation of performance details how the simulations should work and what assumptions can be made. This is a well written standard (and how often do you hear that sentence?) and it includes maintenance factor into the calculations. All the same, a simulation is still just a simulation so you have to go out and measure the light levels on site to ensure that the reality matches up. This is where the next part of 13201 comes in, Methods of measuring lighting performance. This tells you what to measure and what measurement conditions need to be in place before you start. Principally, the environmental conditions shouldn’t affect the measurements significantly and there should be no extraneous light or obstructions that can affect the measurement. This document asks surveyors to carry out a lot of measurements. The time and cost involved in doing this means full on-site measurements weren’t always carried out. In 2007 therefore the ILE (as it then was) published TR28 Measurement of Road Lighting Performance on Site. This is an engineers’ document, based on the original standard but providing practical advice to lighting professionals on how to fill out simplified measurements that can still provide

meaningful data for lumen maintenance. In summary, it lays out a method for measuring luminance and illuminance at a random sample of sites, ideally once a month. The test report describes measuring the illuminance and luminance of an evenly spaced grid of points across a roadway. Where this document really comes into its own is the detailed description of the uncertainties involved in taking an on-site measurement. I’ll break these down into two categories, the ones that are knowable and consistent and the ones that aren’t (and see table 1). By ‘knowable’, I mean uncertainties that are measurable and will be reasonably consistent from month to month. The knowable uncertainties are reasonably straightforward, and should be the same from month to month. The real problems come in with the uncontrollable, difficult-to-measure ones and this is why my original caller wanted to involve my lab in this. For instance, the document says

the measurements should be taken in areas where ‘the light is not obstructed by trees, vegetation, parked vehicles or highway furniture.’ But take the image below of an average urban residential street. As you can see, there are cars on either side of the street, making it difficult to carry out measurements. And bear in mind this is during the day; at night it’s likely to be even more crowded than that. Indeed, every street in my part of town looks much the same as this. We also have to consider the environmental factors that vary from month to month. Moonlight can add as much as 0.3 lux to the measurement and, as we know, variation in ambient temperature will have a significant effect on light output. We also have to consider the contribution of extraneous light (house lights, passing cars and so forth). Cloud cover can affect the local light levels, both by changing the amount of light coming from the sky but also

by increasing the sky glow, reflected from the street lights. None of this is consistent and repeatable from month to month, so can present real difficulties in making lumen maintenance measurements. Compiling uncertainty budgets is part of my job of running a test lab, but the sheer difficulty of putting the above uncertainties into a number that can put error bars on an illuminance or luminance value makes my head spin. There are just too many hard-toquantify variables here. However, there is an alternative to this, where you can take the luminaires off the lighting columns and submit them for independent testing. LUMEN MAINTENANCE MEASUREMENT – THE TEST HOUSE APPROACH I started looking around to see what the state of play was with lumen maintenance testing in the lab and found a document published by the County Surveyors’ Society (CSS) in 2008. This details a study carried out by various bodies in the lighting industry (including the ILP) to ascertain whether the assumed luminaire maintenance factors, as stated in BS 5489, were accurate. Multiple sites were used for these tests, with at least two luminaires selected from each site. The luminaires came from more than one manufacturer.

Exterior lighting and lumen maintenance 33 Crucially, the document stated: ‘In order to get a high level of accuracy in test measurements, luminaires were removed from site and taken to a test laboratory to obtain photometric measurements under test conditions.’ The luminaires were tested for total light output in an integrating sphere, with measurements taken before and after cleaning of the luminaire’s housing. The study concluded the luminaire depreciation was less than expected and therefore the factors reported in BS 5489 were too conservative. However, what really comes out of this work is how much more reliable this approach is compared to conducting measurements on site. When you’re working in a photometric lab, the uncontrollable variables you have to deal with outdoors disappear. In other words: • The temperature and air flow is controlled, so climatic dependence can be neglected. • There is no extraneous light to consider. • There are no reflections from the roadway to consider, because there’s no roadway!

• There is no cloud cover to account for. • There is no need to consider variation in luminaire mounting. So, if you introduce this change into your testing regime, suddenly your results become a lot more accurate and repeatable, month after month. Even if there weren’t a case for laboratory testing based on convenience and accuracy, I believe we would still need to carry out these tests. The results in the CSS document date from 2007, only cover LMF and don’t deal with LEDs. Therefore, we still need to reassess what the LLMF and LSF values are for LED-based luminaires and if they match up with manufacturers’ claims. I have had customers asking me for this information and I have to admit I just don’t know; the data isn’t out there. After all, in a marketplace where people are making claims for lumen maintenance based on expected 20year lifetimes, it is vital to know if the maintenance factor values stack up.

ever under-estimate Daily Mail headline writers. ‘Scientists plan “self-repairing city” with an army of drones that fix streetlights and potholes without being told to’, it screamed back in October. Visions of swarms of drones perched, perhaps slightly malevolently, looking down on us from lighting columns until, slowly, spreading their ‘wings’, they open… Well, perhaps not. Nevertheless, whoever it was who came up with the idea of describing a pioneering research project being led by Leeds University’s School of Civil Engineering as developing (among other things) ‘perch and repair’ robots to repair lighting columns certainly did not help. ‘It’d be fair to say there’s been a lot of media interest,’ concedes the school’s Professor Philip Purnell. ‘If I knew the answer to what these things are going to look like or how they’re going to work then we wouldn’t need the research project. But it might not necessarily be a flying drone, there could be other ways to do it.’ ENGINEERING ‘GRAND CHALLENGES’ The £4.2 million national infrastructure research project was announced in October, is funded by the Engineering and Physical Sciences Research Council and is part of a £21 million pot of money to examine ‘Engineering Grand Challenges’. As well as (possibly) ‘perch and repair’ lighting column robots, the team – which includes Leeds City Council and the UK Collaboration for Research in Infrastructure and Cities – will look into innovations such as ‘perceive and patch’ drones designed to autonomously inspect, diagnose, repair and prevent potholes in roads. It will also investigate ‘fire and forget’ autonomous devices designed to operate indefinitely within live utility pipes, again performing inspection, repair, metering and reporting tasks. And the important word here is ‘autonomous’ rather than, specifically, drone or robot, emphasises Professor Purnell. ‘We are not just investigating the robots themselves but the entire system, everything from sensing and repair capability to autonomous systems. It may well be you don’t need to fly a robot up there to effect the repair. ‘However, one of the advantages a lighting column has over, say, a pipe in the context of autonomous systems is that it already has its own power. It might not be a perch and repair robot, it might be a crawler that goes up the pole, or something else completely. But it is about stripping the whole thing back to its foundations.’ Of course one of the challenges in this context is the sheer complexity and variability of lighting columns. Then there’s the physical difficulty often involved in getting into the housing and making the repair or replacement, often perhaps in bad weather or high winds. ‘One of the things we want to ask is exactly that: why is it so complicated?’ questions Professor Purnell. ‘Why is that we have, say, eight types of bulbs and 17 different poles, or however many there are? Why is it we can’t create, perhaps, standard attachments

or latches that could be retrofitted to make a system that could be amenable to being repaired by an autonomous system, whether a robot or some other system? ‘You have a 50g bulb, say. So why is it we need to have four people and a cherry picker to change it, not to mention the cost of having to close the road or do it in the middle of the night? We’re looking not just at technology and systems but also existing infrastructure and how to adapt it,’ he adds. AUTONOMOUS SYSTEMS The project is running over four years and bringing in not just robotic and civil engineering expertise but also economists and social scientists. And Professor Purnell stresses it is about trying totally to rethink or re-visualise approaches to these challenging infrastructure questions rather than coming up with quick-fix solutions. ‘The suspicion with something like this is always that the end result will be robots taking people’s jobs. But that’s not the case at all. What we’re wanting to do augment the workforce, free manpower to do the more important stuff,

to look at what happens when we can make things go together better. ‘It is a “grand challenge” project so by its nature it is difficult to predict where we will be with it in four years’ time. But we are hoping to have a demonstration system within a year to 18 months to show what might be able to be done. However, this might be one analysing and repairing pipes rather than flying up to repair a lighting column,’ he points out. And whatever answers academia arrives at, Professor Purnell is keen to see industry engaging with this process. ‘Whatever the solutions we come up with, these are not things that going to be rolled out to industry in a couple of years,’ he says. Indeed, the team is hoping to hold a ‘stakeholder event’ in the spring, in Leeds, at which Professor Purnell is looking for industry to get involved as well as other academics and experts. ‘There are so many different systems out there that you cannot hope as an academic to understand the complexity of them all. There’s different bulbs, voltages, heights and so on – you need to understand the complexity of what you’re dealing with, and I think the industry can help with this,’ he says.

SEASIDE SUMMIT For as long as anyone can remember the ILP’s Professional Lighting Summit has been held in the autumn. Scott Pengelly, Vice President Events, explains why the ILP has taken the radical decision to move this year’s Summit to June


raditionally, the ILP Professional Lighting Summit has always taken place in the autumn. It fitted well into the diary to be held at that point of the year and, of course, linked nicely into the presidential year and the AGM. But as time has gone on we’ve begun to have issues with its timing being in the autumn. As the industry calendar has becoming ever busier and more cluttered, particularly the four months from September to Christmas, the feedback from members has been that the Summit has increasingly been clashing with other industry events, not least events such as LuxLive. There are so many events throughout the autumn and everyone is so busy; it’s such a ‘hot spot’ period of the year. We feel spreading things out more will be valuable and welcomed by members. There’s also a potential financial benefit. September is the middle of the party political conference season, which makes it generally a more expensive time of year to host an event.

Summits but we’re also looking to refresh certain elements. In June we have more light into the evening so we’re hoping do a different type of evening event, although the exact details have yet to be decided. And we’re going to make the evening event slightly less formal. Nevertheless, the core of the Summit, the focus, will still definitely be on providing a value-adding CPD event to members of all different types and backgrounds. Our membership is a broad church and we remain absolutely committed to providing an event that caters to the whole range of our membership. Hopefully, too, the seaside in June is going to be an attraction in itself! However, moving the Summit in this way does, of course, create another issue: the fact the presidential year concludes in September, and the AGM will therefore still need to be held in the autumn. What we are going to do this year therefore is have our AGM in October, on 6 October but also hold an additional event alongside it, this year in London.

CALENDAR COMMITMENT For these reasons we’ve decided that, as of 2016, the Professional Lighting Summit will be moving forward in the year, this year to 15-16 June in Brighton. This is a time of year that is generally freer in people’s calendars; there is less competition from other events and so, hopefully, it can give people greater freedom to commit to, and focus on, what’s going on and what’s on offer at the Summit. Having the Summit in June is a trial for this year, even though we very much hope it’s going to work and be popular. With something like this you don’t know whether it’s going to be a success until you’ve actually gone and tried it once. It’s going to be the same length and format as previous

LONDON LECTURE Some of the fine details have yet to be worked out but we’re looking to arrange an afternoon/evening single event, probably a slightly more formal lecture. Last year’s International Year of Light lecture by Professor Russell Foster, professor of circadian neuroscience and head of the Department of Ophthalmology at Oxford University, proved hugely popular and is, I feel, a perfect example of the sort of event that could be a good fit at this time of year. We’ve got a speaker planned in for it, the optician Ian Jordan, whose speech to last year’s Summit on the use of light to treat people with dyslexia, dyspraxia, autism and other conditions was one of the highlights of the event in Chester.

Waterfont Hotel, Brighton: venue for new summer Professional Lighting Summit

So it’s going to be on a topic on the periphery of standard lighting subjects, but it is, I certainly feel, of such interest and difference that it will attract a wide audience. It will be followed by a relatively informal networking event with the new president. Beyond these two important changes, we Ian Jordan: speaker at new October also have a busy calendar AGM event of events for 2016. We have our ‘Lightscene’ exhibition and set of CPD presentations in Sunderland upon Tyne on 21 April and our ‘How to be Brilliant’ series of lectures also starting from that month, to name but two. Do keep an eye on the Diary page in Lighting Journal and online, at SMART CITIES More widely on events, one the things we’re looking do this year because of its popularity is more debate and discussion around smart cities. Smart cities is a subject that everyone is talking about at the moment. Some people have different ideas to others as to what it all means; for some of our members, even just the jargon of smart cities can be baffling. Yet smart cities is not something that’s going away; indeed it is something that will be gradually rolling out and becoming a reality for many. For ILP members, it is clear this is an agenda they are going to have to grasp and understand. That’s why, as an institution, we want to be able to support members and the industry more closely with this agenda. We want to provide ILP members with enough information that they can be on the front-foot with this vitally important issue. To that end, April’s CPD seminars at Lightscene are focusing on smart cities this year. We want to welcome along

a number of other parties because smart cities is, of course, not just about lighting. We need to take into account that it needs to be almost, if you were using a political analogy, a cross-party debate, one encompassing our industry but also city planners and local authority experts, data and software specialists, even community leaders and so on. Lighting is a key part of the smart city agenda, but we have to recognise it is just one part of it. To my mind it’s important that, as both an institution and an industry, we get out there and speak to and engage with other organisations, groups, bodies and industries; that we share knowledge and expertise and, if necessary, even partner with others on joint or collaborative events. There are so many crossovers between ourselves and other industries and I think there are a lot of opportunities we need to look at. For example, we’re looking at supporting the ‘Seeing is Believing’ technology event in November. Although lighting will always need to be the core of our events programme, how we use our events, and how we collaborate more widely through our events, is important. We can use events to help to bring the different arms, the different areas of expertise, within our industry closer together. By being a proactive institution, by being an institution that breaks the ground by reaching out to similar institutions, we can help to lead and shape different agendas. Even more importantly, we can help individual members lead and shape agendas in their own areas. Scott Pengelly is ILP Vice President Events and product manager at DW Windsor

38 Inside the ILP: ILP news


The ILP has appointed a new technical team with a remit to push forward and promote technical excellence and CPD within the profession.

Haydn Yeo: new VP Technical

Haydn Yeo, street lighting team leader at A-One+ and formerly regional technical liaison officer in the Midlands, has been appointed Vice President Technical, and has already chaired his first meeting of the ILP Technical Committee. He takes over from Keith Henry, who has moved a new role of Vice President Highways following a reshuffling of the ILP’s VP structure to split the Highways and Infrastructure disciplines (Lighting Journal, NovemberDecember 2015). At the same time, Peter Harrison, former head of design and additional revenue at Balfour Beatty and now an independent

lighting consultant, has been appointed technical services manager. Peter told Lighting Journal: ‘I see the technical services manager role as a fantastic opportunity for me to continue to work with lighting professionals and to be involved in taking ILP forward.’ Haydn and Peter will work closely with professional services manager Stuart Bulmer, who continue to support the technical remit of the ILP but will now focus more on educational issues, including the development of the exterior lighting diploma. ILP Senior Vice President Kevin Grigg said: ‘With the appointment

Peter Harrison: technical services

of Haydn and Peter, we have a great opportunity to develop and drive forward the ILP technical remit. There is so much to be done – in a sense, too much – so I am confident the new team will harness our resources and focus on the key technical issues facing the ILP and the lighting profession.’

EDUCATION VACANCY PRESIDENT OUT OF ILP Vice President Education Stuart Green has decided to step down from his role, meaning the institution is now seeking a new champion to develop its education programmes. The position is open to any subscribed ILP member and a full job description is available through the website, Applications should be sent in confidence to chief executive Richard Frost ( to arrive no later than Friday 12 February. Interviews of applicants will be held as soon as possible after that date.

ACTION TEMPORARILY It is with sadness that the ILP has to report that President Elizabeth Thomas is temporarily out of action, after having undergone a major operation to remove a benign brain tumour. Assuming her recovery continues on track, Elizabeth has said she hopes to be fully back at the ILP helm by April, and in

time for the annual spring round of lighting meetings and events. In the meantime, Senior Vice President Kevin Grigg has stepped up to cover for her responsibilities, although he will continue to be ably supported by the rest of the executive board, Vice Presidents and regional officers.

RETENTION OF COUNCIL LICENCE The ILP successfully completed the renewal process of its Engineering Council licence in December. A team led by Vice President Membership Guy Harding and comprising chief executive Richard Frost, membership committee member Richard Raynham and

membership manager Chantal O’Sullivan oversaw the regular, fiveyear audit process by the council. This declared the ILP’s procedures to be robust and that there were no ‘non-conformities’ identified. In fact, the ILP scored 15 out of a possible 16 points.

The auditors also recommended that a previous special condition of having a council liaison officer attend all membership interviews be removed. The successful audit means the ILP’s licences will now be renewed for a further five years

PEDESTRIAN LIGHTING Members are being invited to comment on a discussion document on pedestrian lighting written for the ILP by Professor Steve Fotios, professor of lighting and visual perception at the University of Sheffield and Peter Boyce, senior researcher at the university. The document reviews what is currently known about the desirable characteristics of lighting for pedestrians and considers the extent to which the existing UK standard is adequate. The document can be read at under ‘News’.

Inside the ILP: ILP news 39


YOUNGEST ILP MEMBER A 15-year-old boy from Wigan has become the youngest member of the ILP in recognition of his passion for street lighting. Ben McKenna collects sodium lanterns and LEDs as a hobby and, according to his family, even preferred to receive light bulbs rather than sweets as a child, the BBC reported in December. The lighting team at Wigan Council decided Ben deserved to become an ILP member after his grandmother got in touch before Christmas to ask

where she could buy him one of the LED lights the council has been installing across Wigan. He was also given a second-hand outer bowl and has spent a day with the street lighting team. The council in 2014 announced an £11 million plan to switch the town’s 31,000 street lights to LEDs. The council’s technical and design officer Chris Pennington told the BBC: ‘He is very knowledgeable and was asking us about what qualifications he needs to progress.’

The ILP is reminding members in the throes of paying their 2016 membership subscription that all ILP members are bound by the Institution’s Code of Professional Conduct. This was reviewed by the ILP Council towards the end of last year, and so members are being reminded of their continuing duty to behave ethically. The code has been updated so that it specifically now refers to the use of social media in this context. The code is available to view on the ILP website under the tab ‘Membership’.

40 Independent lighting design


ighting is one of the few things we come across globally that needs no explanation – we all understand it. Or rather, we all know we need it. It makes plants grow, it allows us to see, it can tell us the time and it can make us feel happy. Nevertheless, as any lighting professional will well know, for someone to assume they ‘understand’ light because they understand the above would be simplistic. Light does need some translation because where you are in the world alters how you value light. This idea of the value of light, and the more frequently talked about ‘quality of light’, is the core of a lighting designer’s toolkit. To that end, for next month’s Light + Building 2016 trade fair and exhibition in Frankfurt (from 14-15 March), the IALD has brought together specialists from around the globe to tell you about their lighting perspective or, as I like to think of it, ‘the light where you live’. We’d love to see you there – and our forum will be in room Aspekt, Hall 3 Westside, Level C, Messe Frankfurt – and this is what you can expect. VICTOR PALACIO, IALD PRESIDENT, IDEAS EN LUZ, MEXICO CITY, MÉXICO Victor will start off our free-toattend series of talks. He will share information and personal views on possible scenarios for the profession and the potential ways of practising it in the years to come. He’ll argue that lighting design has left behind its ‘childhood’ as a profession and now faces the potential of ‘young adulthood’, a period where it will be necessary to define strategies for the future. As Victor states: ‘Many questions will arise during this transition, including: will lighting design become a technical consultancy, will there be the room, time and money for a design-based profession in the built environment, will there still be a future for independent lighting design practitioners? ‘The challenges are big: the evolution from a “components” based industry to an “integrated systems” one; players in the market offering a wide variety of services (including design); codes and restrictions that ultimately limit the design approach; independent practitioners who find business opportunities under many different models. ‘On the other hand, lighting designers are becoming more aware of the immense potential of light to transform the world in more fields than we ever imagined before. ‘As the profession evolves, its social role will become more important – light has increasingly relevant implications in human health, environmental impact, and the economies of cities, public communications, people’s wellbeing and more. ‘Yes, there is a future for lighting designers. It’s up to us to provide vision and give direction to it.’

The Light + Building fair in Frankfurt is but a month away, and the IALD will be bringing together specialists from around the world to discuss lighting design, as Emma Cogswell outlines Lighting Journal February 2016

ANNA SBOKOU, OF ANNA SBOKOU LIGHTING DESIGN, ATHENS, GREECE Anna’s imaginatively titled talk ‘Spice with a Touch of Lemon’ will focus on the different forms of practice and conduct that a lighting designer in Greece adopts. Lighting design has a universal base that allows its practitioners to easily move and work around

Independent lighting design 41 the world. Nonetheless, cultural and local characteristics vary substantially and affect the work process and dynamics of a designer. In countries where independent lighting designers are not widely recognised, the work process can vary even more. KRISTIN BREDAL, OF ZENISK, OSLO By contrast, Kristin Bredal will send us a postcard from Norway, speaking for the Norwegian Lighting Association, Lyskultur, whose main objective is to contribute to the continuous development within the area of light and illumination. In a country where the winter is long and dark, there is an obvious need for good lighting solutions. Lyskultur works continuously to provide municipalities and contractors with sufficient information regarding master plans for lighting in town and urban environments. GERD PFARRÉ, OF PFARRÉ LIGHTING DESIGN, MUNICH, AND ANDREAS SCHULZ, OF LICHT KUNST LICHT AG, BONN Multi award-winning German lighting designers Gerd Pfarré (a fellow of the IALD) and Andreas Schulz will do a joint talk on what it has meant to be a lighting designer in Germany over the past decades. They will talk about their views on applied creativity and the values of being independent, using past examples of their own work to demonstrate the highs and the lows. As well as these keynote speakers, we will be joined in Frankfurt by lighting designers from France, Italy and Spain, each giving their perspective. There will also be experts in lighting advising us on new trends in LEDs, the Certified Lighting Certificate and the IALD’s role in public policy. ‘ARGUMENT’ – A LIZ WEST INSTALLATION If you’re looking for a shot of colour whilst in Frankfurt look no further than the immensely talented Liz West’s ‘Argument’ installation in the Designers Lounge, Hall 3 Westside, level C. This will be a free drop-in centre for designers to recharge their batteries, meet others and have some time out from the show. It will be open from the Monday to Friday of the show. Manchester lighting artist Liz uses light as a material that radiates outside of its boundaries and containers. She playfully refracts light using translucent, transparent or reflective materials, directing the flow of artificial light. Liz will be the IALD’s artist in residence for Light + Building and, as well as the installation, will be giving in a presentation where she will discuss the role of light in her recent work, including her acclaimed ‘Your Colour Perception’ and ‘An Additive Mix’. Emma Cogswell is IALD UK projects manager
