A new way of work for Deloitte atThe Ridge

Lighting plays key role at state-of-the-art university building

Ed Space

A s with much else, the way we illuminate the spaces we inhabit is set to change along with our changed priorities since the arrival of the pan- demic. Pre-existing trends in workplace wellbeing, sustainability and online communication will ac- celerate, while new uses of retail spaces, public space and even the home will emerge. The design of lighting will have to respond to these shifts so that it plays a key role in articulating our new built environment. Here are a number of ways lighting could change post-COVID. • Workplace lighting will get creative: This will be a megatrend in offices. Progressive employers will invest in their interiors, and statement lighting, to foster loyalty, belonging and community. Expect more boutique style interiors, food and beverage areas and meeting rooms. • There will be more emphasis on light qual i ty: A trend before the pandemic, the move to higher quality lighting – low glare, low flicker, higher colour rendering – will accelerate as wellbeing in workplaces becomes paramount. • Concept stores will drive retail lighting: Concept and ‘brand experience’ stores will increasingly be seen. These store-as- showroom spaces typically eschew rows of spotlights in favour of embedded lighting in light boxes, fixtures, tension-fabric units and display cabinets. • Expect more personal ised control in offices: The lighting industry has been talking about personalised lighting for years, but it looks set to have its moment thanks to affordable technology, the advent of private working spaces and a desire to lure employees back to the workplace. • Lights will be made to circular principles: Increased concern for the environment post- pandemic will see more lighting equipment begin to bemade to circular economy principles. • Upper-room disinfection lights will be a thing: UV-C lamps – mounted above people’s heads and shielded from sight – will increasingly be used to kill airborne viruses. But just how big this market this turns out to be, when everyone has had a vaccine, remains to be seen.

• IoT lighting will, eventually, arrive: The future, we once once told, is lights connected to the cloud as part of the ‘Internet of Things’. That has not happened. However, the technology is becoming more accessible – and cheaper – so there is an inevitability that it will arrive in some form. • Say goodbye to blanket uniform lighting: In offices, expect to see more meeting rooms and the introduction of quiet places where people can concentrate. These will require different lighting approaches, leading to a more complex product matrix. • Catering for the desktop-to-laptop trend: At one time, the lighting industry was obsessed with reflections on desktop computer screens. No longer. More and more employees will migrate to laptop use, which should allow more design freedom, but we will still have to be mindful of glare. • Pendant lightingwill increasingly appear in workplaces: Pendants and other decorative- style lights – once the preserve of the boutique hotel – will increasingly appear in workplaces as we move from rows of desks with employees emailing each other to collaboration, team building and ‘knowledge sharing’ spaces. • Visual balance will move up the agenda: Avoiding substantial changes in light levels as occupants move from one space to another, or indeed across the same open-plan space, will become an increasingly important consideration of lighting design as part of the light quality agenda. • Forget human-centric lights; think colour tuning : Daunted by the science, many lighting designers, consultants and clients are reluctant to apply human-centric principles. However, colour tuning light, which mimics dynamic daylight, will prove a more popular way to give employees a more natural light. The Coronavirus pandemic has changed everything. Its impact on global wellness and the economy has forced organisations in every industry – including our own – to flex and evolve, both in real-time and in the long-term.The well-known proverb, ‘Necessity is the mother of invention’ could not be more apt at this time.

A restoration with a light touch The restoration of the ensemble of heritage buildings on Buffelsdrift, west of Ladismith in the arid Klein Karoo region of the Western Cape, by SAOTA and Jaco Booyens Architect, a specialist in clay buildings, recently won the gold medal at the seventh edition of the international Domus Restoration and Conservation Award in Italy.

Q&A with Jaco Booyens and Greg Truen Q: Howwas lighting chosen so as not to detract from the building’s heritage? A: On the outer facades we used two types of lighting. The lights next to doors or entrances when entering the buildings were custom designed and manufactured lights based on Gawie Fagan’s Groot Constantia interpretation of a traditional lantern light. The frames are simple 16 mm mild steel square tube powder coated in black with clear glass covers, built into the mud with two horizontal bars as support. Throughout the scheme these lights were placed just above lintel height. The front facade entrance of the main house has two lantern lights; one on each side of the door. The lower lights were designed to be as unobtrusive as possible. We decided on mild steel folded plate boxes powder coated in white and built-in flush with the mud walls to create a slot where the light shines downwards. It reads on the facade as a vertical slot emitting light. They can be seen on the front facade as well. These lights also came in handy in the interiors, for instance, to light the Wine Store staircase landing and some of the bathrooms. We mounted one above the freestanding bath and at foot level in the small bathroom’s shower. The lights were also used to light the parking area and as footlights on stone stairs going down from the parking area to the main house kitchen entrance. Q: Were there issues or challenges with wiring the lighting in ‘old’ walls? A: Wiring in mud walls is actually a lot easier

to install. To hide conduits in a softer material like mud is much less of a fight than grinding into plaster and brick. The whole process can be done without power tools. Lime plaster, being much more ‘plasticy’ and with a more ‘alive’ type surface makes covering it up also quite easy. Q: The interiors feature an assortment of interesting light fittings – can you tell us more about those? A: The internal l ights were much more contemporary than those outside. The strategy for the internal lighting was to use spotlights for task lighting and to accent artworks. For general mood lighting, we used tabletop lighting, which creates warm zones in the house and fills the space with a general low level of lighting. We used strip lights from Province Lighting fixed to the overhead original Yellow Wood beams and ceilings so as to keep the lights in the background. Task lighting in the bathrooms and some pedestal lights were specifically chosen to be contemporary. A: The electronics of modern dimmable LED lighting are quite sensitive. We had some issues with the so-called dirty electricity in the countryside. I would propose the next time round to try and get the lighting circuit specifically to be run off grid with solar and an inverter to give the lights clean, high quality electricity. A fairly small system should be able to carry the load for this. Q: Did the electricity supply to the remote area impact your lighting decisions?

T he restoration involved a cluster of Cape build- ings in a valley beneath the Swartberg moun- tain range, consisting of a main house and two barns, plus a store. A short way off is a flat-roofed building, typical of the Ladismith style, which was originally used as a wine store. Other structures on the property include a contemporary shed, a cottage further up a hill and a graveyard. The house, barns and wine store were all restored. SAOTA director Greg Truen, who acquired the farm in 2016, notes that while minor additions and modern alterations had been made to the buildings, the original house, was “in good condition, considering” and that the barns were “fundamentally untouched”. In the main house, evidence of earlier

refurbishments in the 1970s, were stripped out, while modern kitchen and bathrooms were inserted in an adaptive approach to conservation. A new pump house was added near the dam wall on the property. Its design and construction were an experiment in contemporary architecture using the same materials and techniques as the heritage buildings, including poured mud or ‘cob” walls, as

well as brick vaulted roofs. The landscaping around the house took the form of a series of low terraces. L i c e n c e s t o g r a z e livestock on the land date back to the mid-1700s, and it is clear that it was farmed before the 1800s. The main house on this portion on the farm dates back to 1852. Hans Fransen’s seminal study, The Old Buildings of The Cape, records “three old buildings … all with Prince Alber t - t ype end - gables ( ho l bo l wi th hor i zont a l string courses)”. The main T-shaped homestead, he says, “has massive lof t steps at the side and original

Where modern materials were introduced, they were carefully selected. The shower (in the recess originally used for a fireplace), for example, has been clad in terrazzo slabs, and in the kitchen, a contemporary island has been inserted, also clad in terrazzo. “We looked for a contemporary material that spoke to the original materials,” says Truen. The concrete and aggregate in Terrazzo resonate with the stone and cement paving. “The terrazzo felt like a way to work between the old and the new, where the new felt like it had some kind of genesis in the old,” says Truen. The kitchen block also makes it possible to keep the kitchen and dining areas integrated, making it a central social space, while a 200 mm raised barrier above the counter ensures that the food preparation area is unobtrusive. Appliances are stored below the counter. “There are no contemporary appliances sitting at higher levels other than this extractor fan,” says Truen. One of the only contemporary interventions was the addition of a double-sided fireplace between the kitchen and lounge area. Recessed lights were used on the exterior walls to keep the walls unmolested by modern technology. Where lanterns were added, on either side of the front door, for example, and elsewhere on the main house, as well as on the wine store, they were custom made. Their design took cues from lanterns the legendary Cape modernist architect and restoration maestro Gawie Fagan designed for a wine cellar at Groot Constantia, one of Cape Town’s most famous historical wine farms. Fagan played a pivotal role in “figuring out a way to interpret Cape detailing and reference it in his modernist work”, explains Truen. Other buildings The Wine Store The outbuilding that is referred to as the wynkelder in reference to a time when grapes were grown on the farm, is a small flat-roofed structure that has been restored and converted into a living unit. It was badly damaged and had been clumsily altered. An incongruous timber pergola and a brick fireplace had been added to the exterior. The fireplace, however, had delaminated from the wall and was collapsing. The walls were also badly damaged by

holbol stoepbankies”. The house and barns had been constructed according to the usual technique used by Dutch settlers in the Cape, with walls of poured mud or clay, cast layer by layer about 700 mm wide. “This method of construction – ubiquitously used by Dutch settlers, trekboers and later Voortrekkers – requires a source of clayey ground into which is added ‘a good proportion’ of sand and grit, possibly straw or dung, combined in a pit, all trod through by oxen-hooves in span,” writes Fisher (quoting William John Burchell’s Travels In The Interior Of Southern Africa ). Truen and Booyens opted to use a thin lime plaster on the interior walls between the central living room and the bedrooms on either side, not only expressing the original texture of the mud wall, but also, as Truen puts it, leaving “a little of that construction history visible, so you can get a bit of a story of how these building were put together”. In the living space, the original Yellow Wood beams and ceiling were intact and could be restored. The timber floors, however, had rotted and were replaced with poplar planks, consistent with the originals, kiln dried in Oudtshoorn. The screed floors of the T-section, which was converted into a combined kitchen and dining area, bathroom and front stoep were all refinished using “stone pavers taken out of the veld”, as were the kitchen courtyard and front stoep.

ideas we had to do with contemporary architecture built using traditional techniques,” says Truen. The building forms a connection between the landscape and the dam wall. Its earth-coloured walls take their cue from the poured-mud walls of the heritage buildings. “It’s a technique somewhere between rammed earth and working with concrete,” explains Booyens. “You could almost say it’s a primitive form of working with concrete, but instead of concrete, we worked with mud.” The walls are more than a metre thick, and have been left unpainted, expressing their materiality and blending with the landscape. The vaulted brick roof was an experiment in construction devised to simplify the expensive and highly skilled labour usually required to construct vaults. It involved creating a system of steel beams and a plywood template, and building the vault one row at a time, which proved both cost efficient and appropriate for the skills available locally. “When we took the shutter out, it stood up, because it was a real catenary arch,” says Booyens. The rest of the roof is planted, and steel waterspouts cantilever far out from the walls so that water draining from the roof does not fall against the wall, a technique adapted from vernacular West African adobe architecture. “For me it was a really interesting experience to go and find materials on site, and then build something that is so fundamentally in tune with the climate and performs so much better than any contemporary building,” says Truen. “There are definitely lessons there.”

termites and the floors and ceiling rotted. When repairs began, it was discovered that the wine store had originally been a single-level building, and its parapet was raised in the 1970s to allow for another level so it could be used as a house. “When we repaired the plaster, we could see that the bottom part of the building was made out of poured mud, and then as you go up, there are some sundried bricks, and thenmore contemporary bricks right at the top,” says Truen. A somewhat clunky staircase has also been added. The repairs and restoration of the wine store involved reorganising the ground level so that it could function as a living area and kitchen, and locating the bedroom and bathroom on the mezzanine above. The ground floor was levelled and paved in stone harvested from the surrounding veld. The rotted upper floor was replaced with SA pine, which was limewashed. The roof upstairs was finished with poplar beams and a rietdak ceiling. “We had to create a new stair between the levels,” says Truen. “Of course, that raised the question of how you insert new fabric into old fabric.” Booyens designed a new self-supporting steel staircase as a contrasting contemporary insertion. “The staircase doesn’t touch the original structure of the building,” he says. It floats above the floor and is set slightly apart from the walls, connecting at a single point on the floor and at just one point on the mezzanine level.” The exterior of the wine store has been painted pink partly in reference to the historical practice in the karoo of mixing lime to make a light red or pink colour, and partly in an exploration of some of the historical connections between Cape and Mexican architecture. Pump House The pump house is a new building constructed in response to the need for an irrigation building. “It was an opportunity to experiment and test some

A new way of work for Deloitte at The Ridge Following on from its successful completion of Deloitte’s new Africa headquarters at Waterfall City in Midrand, Paragon Interface has just completed a new workplace for the professional services firm at The Ridge at the V&A Waterfront in Cape Town.

T his was a high-profile project for the interior architecture company Paragon Interface, part of the Paragon Group, as The Ridge has just been awarded a 6 Star Green Star Office Design rating by the Green Building Council of South Africa (GBCSA). “Maintaining the design integrity of the base building architecture while successfully incorporating the distinctively Deloitte brand experience was our aspiration for the interior of

this ground-breaking ‘green’ building,” highlights Paragon Interface Director Claire D’Adorante. “The result has been a project that we are immensely proud of. The Ridge has quite a unique aesthetic – it’s industrial but still very elegant and well-detailed in response to the technical requirements of the sustainable design brief.” The Ridge is the apex of the new Portswood District green development at the V&AWaterfront. It has a gross lettable area of approx. 8 500 m 2

and consists of ground, plus three levels of office accommodation and three basement parking levels. The ground floor accommodates the more public functions such as a Deloitte reception, client-facing meeting rooms, a staff restaurant and a Vida Café that can service both Deloitte employees and the public realm through a service hatch inserted into the covered entrance façade. The ground floor experience is completed by Deloitte’s ‘Xcelerator’, an immersive environment where clients can experience the potential of digital transformations in an innovative environment that enables the creative development of customised digital solutions. To facilitate and encourage active movement for both employees and visitors, The Ridge has a light- filled internal atrium conceptualised as a street that

runs through its centre. The workspace planning focuses on activating this street edge through the deliberate positioning of agile workspaces around the atrium to create a bustling working corridor. It includes a balance of collaborative workspace such as touch-down points, casual lounge spaces, focus rooms and pods. Social relaxation areas are positioned in the vertical circulation core. Lifts and a sculptural steel staircase allow employees to easily connect with each other between floors. Newways of working such as desk-sharing practices are also being successfully implemented here, aligned with Deloitte’s global workspace practices. Apart from the application of similar branding elements in the signage, finishes and colour scheme as at Waterfall City, The Ridge has a distinctively different atmosphere. Extensive use of natural materials such as exposed concrete, timber and glass echoes the external façade. The indoor planting completes a holistic wellness experience for users. Lighting design From quite early in the process, we had a very good idea of what we wanted to achieve with the light,” says D’Adorante. While extensive smart lighting was initially considered, “some areas such as the client meeting suite and Xcelerate area are on a DALI control system allowing each light fitting to be addressed individually,” she says. The majority of the lighting is also motion sensor controlled in order to save on electricity. Due to the industrial design aesthetic, special consideration had to be given to the light fixtures which were sourced. “The reduced amount of ceilings, however, gave us more flexibility and opportunity to explore a wider variety of fittings,” says D’Adorante. “With the darker surrounding, the lighting also seems more pronounced, as if every light source has become a feature. The fact that the light stands out more with the darker background compared to standard white ceilings also forced us to think a bit more about what the end result would look like.” In terms of providing unique forms of lighting to the diverse interior spaces, D’Adorante notes that there were quite a few different principles used for the respective spaces and Paragon Interface had to find a balance between what they wanted, the Greenstar lighting requirements, the different acoustic/ceiling solutions required, and green building limitations. “It was actually quite a complex process to get to the end result for all the different areas,” she says. “In short, we had to use normal white 4000 K light fittings for both meeting

rooms and workspaces as part of the Greenstar requirements. In the meeting rooms and general office space we focused on positioning the light fittings where they would be most required and effective, such as directly above the desk.” The designers wanted the cof fee shop, restaurant and bar to feel cosier, so they opted for warmer and lower lighting levels in these spaces. The meeting and training rooms all utilised the same light fitting where the light fitting replaces the ceiling tee – the final pattern was mostly a result of Greenstar requirements where the electrical engineer and Paragon Interface had to work together closely to find a pattern they were happy with aesthetically, but which also had an equal spread of light. “Most of the lighting in the officewas considered to be both functional as well as decorative,” she notes. “One purely decorative lighting fitting which we wanted to include had to be value engineered out.” The back of house areas such as the kitchens are the only areas with regulation drop-in lights and light ceilings for an equal spread of light across the room.” The majority of the lighting was supplied by LED Lighting SA. A unique interior Perhaps the biggest differentiator at The Ridge is the presence of exposed slabs and services, a technical requirement of the innovative chilled slab cooling solution – one of the many unique sustainability features of the building. Special acoustic panels float underneath the slabs to provide appropriate levels of sound absorption for a comfortable office environment and suspended linear low-energy LED lighting between the panels follows a similar design rhythm. “From the beginning The Ridge was always going to be unique, and the interior really needed to respond to that brief. At the same time, it aligns the threads of Deloitte’s branding philosophy and the workplace strategy implemented at Waterfall City,” says D’Adorante. The sustainability features at The Ridge that contributed to its green rating from the GBCSA include energy-efficient and passive climate control measures, the use of renewable energy, sustainable water handling, reducing the carbon footprint of the building and a focus on the use of natural lighting, including natural ventilation through openable windows. Energy performance has been integrated fully into the design, which maximises natural light and ventilation, and manages water and waste resources efficiently .

Lighting plays key role at state- of-the-art university building The Jan Mouton Learning Centre is a contemporary, multifunctional learning and teaching facility on the central campus of Stellenbosch University. The building is located on the knuckle of the primary campus circulation routes, and houses state-of-the-art technological groupwork infrastructure for future orientated lectures, streaming, conferencing, and classes.

N estled between the Langenhoven (Neelsie) student centre, and the Polymer Science building, the Jan Mouton Learning Centre will serve as a general learning and teaching facility at Stellenbosch University (SU), where students, staff and stakeholders of the University and the

broader public can interact with each other. “Despite advances in technology and the rapid developments in distance learning, there will always be a need for personal interaction while learning. This centre, with its various lecture rooms, breakaway rooms and big open spaces, makes

12

interaction so much easier,” says Prof Stan du Plessis, Chief Operating Officer at SU. Wo r k on the cent re, wh i ch accommodates more students than any other current teaching space on the SU campus, started in October 2017 and opened to all SU students on 15 March 2021. According to Du Plessis, the c l assrooms and aud i tor ium are equipped with state-of-the-art smart technology, which will furthermore “enable students to be connected to cyberspace seamlessly,” and add to an improved learning environment. The centre also has a low carbon footprint, which includes a greywater system that serves the ablutions. Group-work classrooms respectively

LiD Q3 - 2021

Interior lighting On the ground floor, the building has two large auditoriums, two lecture halls, and a computer centre. Regent Lighting Solutions (RLS) was approached for a lighting solution, which included: • Linear lighting and Kibo 145: In conjunction with the Kibo 145 downlight, the Linear Pro 70 was employed to provide the best possible lighting output for the different lecture halls on all floors. These two products work well together to reach the required lux levels, not just visually but also functionally. The Linear Pro has a continuous design for the angled ceiling detail to give the auditorium beautiful light lines. These luminaires are the highlight of the interior of the building as they are the main lighting application throughout. • Shuttle Double : This was specified in the hallways for all floors. • Linear Micro 33: This was utilised for the ablution areas on all floors. The Linear Micro is suspended in the middle of the area; the goal was to create a more intimate atmosphere than a public restroom. • Nemo: This downlight was used to light up all entrances into the auditoriums from the 1 st to the 3 rd floor. • Canolux: Used in the stairwells between the

seating 350, 270 and 150 wi l l provide the flexibility for lecturers and students to adapt their environment to facilitate discussion and teamwork. Another huge advantage is that the Jan Mouton Centre was designed according to the principles of universal access, ensuring that people with disabilities can use the whole facility, its restrooms, auditorium and classrooms with ease. “The new centre sets the benchmark for future development of buildings on campus. The learning spaces were specifically designed to cater for the modern pedagogies developed around interactive and hybrid learning. “The Jan Mouton Centre will also expand our physical learning environment, which will in turn enhance our learning and teaching capacity. It will be providing a bigger and better space, where future learning will take place and make the University even more accessible to more visitors,” says Du Plessis. Unlike most academic buildings on SU’s campuses, no single faculty will be the building’s custodian. The centre will also be used for conferences, which will give access to people outside the University as well. The centre will have ample parking space in the basement and outside of the facility.

floors, achieving an aesthetic look as well as the required lux levels for staircases. Exterior lighting With regards to lighting the exterior of the building, RLS supplied: • Shuttle Double: Creates a nuance for the external perimeter lighting of the building, and was used in conjunction with the Shuttle ceiling, which is mounted on the concrete soffits. • Shuttle Ceiling: External perimeter lighting mounted on the concrete soffits to light up the walkways around the building leading to the entrances and stairways. • Geo Bulkhead: General lighting of the internal /external stairwells and substation areas. • Lumina 1500 mm: This luminaire was chosen to light up the side of the building as well as the building’s name. • Lugo: Basement parking and plant room around the Jan Mouton building. Lighting controls Venues such as auditoriums and lecture halls pose a major challenge, not only to the lighting

installation but also to the level of control required. High-quality light is required to maximise the comfort and productivity of the scholars whilst control of the lighting is crucial for the lecturer to truly capitalise on the session. Auditoriums have many uses and one needs to be able to effortlessly adapt the lighting to the use of the environment. Bright focused lighting on the front stage helps visual communication by enhancing facial expressions or reducing light intensity on the front stage to prevent whitewashing on the screen during a presentation or video. The client’s requirement for the ground floor auditorium was to control the room as one entity but also in the same instance as single entities, meaning that it had to be controlled as a left-hand side and a right-hand side of the room. RLS designed the control system using its daliTECH Omega product range. A combination of configurable scene pads for physical interaction and using motion sensors ensured a perfect balance of user control to best suit the task at hand as well as providing energy savings. The system was commissioned according to the client’s requirements for specific scenes, similarly, this was done throughout all the floor levels. Here is an example of one of the scene pad settings which are mounted at the lecturer’s desk. Scenes 1-4 (100%, 75%, 50%, 25%), scenes 5 and 6 as dimming up and down respectively and scene 7 as presentation mode. Presentation mode, for example, turns all downlighters above the lecturer’s desk off to allow for video presentations on the screen and the rest of the luminaires drop down to 25% which provides an adequate light level for note-taking. The first and second-floor auditoriums had the same split room concept as the ground floor, with one key difference; both halves of the rooms also needed to be able to be controlled together, as a single large room. Control protocols each have their owns set of rules, which need to be adhered to for the systems to work. daliTECH Omega is flexible enough to accommodate small and large environments by combining different products. By doing so RLS was able to achieve the same level of operation in the larger auditoriums as described in the context above.

Light for industry and engineering

In these days of increasing digitalisation, more and more work processes run completely automatically. Industry 4.0, where man and machine communicate directly with one another using intelligent digital systems, is within reach. As an active part of the overall system, light will work as a connecting element – for example, to collect data or to aid navigation.

P roduction processes in industrial companies are now changing at increasingly shorter intervals. The same space regularly has to satisfy different utilisation scenarios and visual requirements. Lighting systems should have a high degree of flexibility so that they can be quickly adapted to layout changes, reducing production downtime to a minimum. Trunking systems represent an especially good basis for lighting, as the luminaires can be moved quickly and easily without any tools. Adaptability can be further enhanced by using an ATIVO multisensor. Motion and light measurement zones can be changed with a simple click of the mouse. Time-consuming repositioning of sensors is therefore a thing of the past. Industry 4.0 has the potential to optimise industrial processes in terms of adaptability and productivity even further in the future. In this context, lighting can play a significant role. For example, the level of illuminance automatically adapts to the task at hand and therefore always provides the perfect lighting conditions. Furthermore, connecting

communication and machines and systems and products can further increase productivity in the form of reduced production times, data analysis or lower error rates. Productivity The demands on workers will noticeably increase in the future. Routine functions will become more and more automated, while increasingly complex tasks that demand manual intervention will require appropriately trained employees. Beyond that, there is the issue of democratic change. Shifting age patterns in the workforce bring about new workplace requirements. Good light quality is the basic requirement for the well-being of employees, helping to make sure that they are motivated and can concentrate sufficiently to deal with such highly complex tasks. This increases performance and markedly lowers error rates. In addition to its visual and emotional effect, light at the workplace is also important in terms of biology. Light with shortwave, blue spectral components has an activating effect, whereas warm-white light

carbon footprint and often leads to higher energy costs. Selecting the right lighting and controls system therefore contributes significantly to an optimised use of energy resources. Advanced electronic control gear with a dimming function can cut power consumption by up to 25 percent. The intelligent use of presence sensors offers the possibility to further decrease the need for artificial light by 20 to 40 percent. Centrally controlled time management systems ensure that the lighting is only switched on when it is really needed. Daylight sensors dim luminaires depending on the amount of daylight available, therefore guaranteeing a constant level of lighting. Application overview Diversity demands versatility: Industry is made up of many diverse areas, fromheavy industry to clean- room applications. Lighting has to satisfy a variety of requirements and comply with the appropriate standards depending on the task. Zumtobel offers the right lighting solution for every requirement. In this way, every industrial application can be taken care of in the best possible way. Maintenance: Maintenance work in logistics warehouses with high ceilings is a time-consuming and expensive task. The luminaires are often very hard to reach, which is why replacing defective lamps or ballasts also takes a lot of time and effort. Durable LED luminaires reduce maintenance requi rements to a minimum. Innovative constructions reduce dirt accumulation and mean that luminaires stay cool and are easy to clean. Energy and cost savings : Long operating hours and immense spatial dimensions lead to high energy consumption. At least 20 per cent of operating costs in a logistics facility are for lighting. Efficient LED luminaires with targeted light control enable long-term reduction of these costs. In addition, lighting management systems with corridor functions can reduce lighting usage times – especially in those areas that are only occasionally used by people due to increasing automation. Ideal illumination: Fork-lift drivers frequently have to look directly into light from a luminaire when loading and unloading high shelves. Ideal

has a relaxing influence. Biologically effective lighting can provide long-term support in terms of employee health, particularly in production areas without natural daylight or for night-shift operations. The natural sleep/wake rhythm is enhanced through targeted use of illuminance and light colours that imitate natural daylight. Reliability Industrial and manufacturing enterprises are extremely diverse and characterised by very different environmental conditions. The demands on lighting in individual applications are equally diverse. No single solution can meet the demands of every industrial application. Identifying the prevailing environmental influences therefore plays a significant role when selecting the right lighting. The technical components of a luminaire should be protected against overheating in the case of very high temperatures. No liquids or foreign objects should enter the housing in areas with increased moisture and dirt accumulation. During intensive cleaning processes and in chemically polluted ambient atmospheres, special attention must be paid to the right choice of material in order to provide resistance against the substances present in the application. Application-specific standards and guidelines often contain lighting related requirements that have to be fulfilled. Checklists can provide an overview and record the existing general conditions in an industrial project as comprehensively as possible. Efficiency Energy requirements in industrial enterprises are especially high due to long operating and production times. This has a negative impact on the

and are equipped for a long service life with the lowest possible reduction in luminous flux. High degrees of protection and carefully designed luminaire sur faces minimise unwanted dir t accumulation, so that expensive cleaning and service intervals can be deferred. Var iable work tasks : When i t comes to metalworking, one task rarely takes place in the same workplace for the entire service life of the lighting. If tasks in the production area change, lighting conditions also have to be adapted. Trunking systems are characterised by a high degree of flexibility and adaptability. The position, type and number of luminaires can be quickly and easily altered to suit the new visual task. Glare limitation: Body and assembly work in the automotive industry are demanding tasks that require perfect lighting conditions. As shiny metal surfaces are often found on production lines, the risk of direct glare and glare by reflection is particularly high. These have a negative impact on error rates, concentration and fatigue. Highly selective luminance and visible LED light points should be avoided to reduce disruptive light reflections and subjective glare sensitivity. Luminaires with uniform, homogeneous light- emitting surfaces are recommended. If luminaires are arranged laterally and parallel to the production line, unwanted light reflections can be reduced. Maintenance: Replacing defective lamps and luminaire components can be time-consuming and costly in the automotive industry. Production processes have to be interrupted and the areas that need servicing are often in high halls that are difficult to reach and that require the use of lifting and climbing aids. Durable LED luminaires with higher protection and a carefully considered

light quality with good glare suppression not only enhances productivity and motivation but also increases safety. Optics optimised for logistics guide the light in a targeted way to the place where the visual task is being conducted. High-bay warehouses benefit from the use of luminaires with narrow-beam optics that provide even illumination in vertical shelving areas. Horizontal transportation areas are also well illuminated. High flexibility: Trunking systems offer added flexibility to respond quickly and easily to altered layouts. If LED optics are replaced, the general appearance of the luminaires remains unchanged, despite the different light distribution. Shiny surfaces: The range of visual tasks in the metal industry is particularly wide. General operations and detailed inspection work often occur side by side, even though they have individual requirements in terms of uniformity, glare and illuminance. Disruptive glare caused by reflection, which often occurs when working with reflective materials, can be minimised with uniform light distribution and the correct luminaire arrangement. This helps workers focus and limits potential sources of error. Oily environments: Luminaires are regularly exposed to coolants, oil vapours and metallic dust in metal-working applications. Luminaires made of PMMA with high IP protection classes offer maximum robustness in these kinds of environments and prevent the entry of foreign objects. Conversely, optics made of PC should not be used, as they can break upon direct contact with oils and lubricants.

In pharmaceutical industries, safety isn’t just important, it is mandatory.The environment must be maintained according to strict guidelines and standards that cannot be compromised.

Durability : Our industrial LED luminaires are specially designed for demanding environments

Maintaining high standards of hygiene is a prerequisite protocol for the food industry. When it comes to the produc- tion site, the modern food industry has higher standards and is usually advisable to have luminaries with an IP 65 rating.

recommended to help ensure a reliable assessment of even the smallest colour nuances.

design help to extend service intervals and reduce maintenance costs. Silicone-free content and degree of protection: Si l icone can negatively influence the fluid characteristics of material surfaces, which may disrupt painting processes and lead to visible errors on the product. Strict regulations often apply in the automotive industry, which prohibit the use of luminaires containing silicone in order to minimise the danger of contamination. In addition, using a higher degree of protection of at least IP5X is recommended for optics and LEDs in car manufacturing. Flying sparks caused by cutting work cannot penetrate the housing, helping to avoid potential soiling of and damage to the interior workings of the luminaire. Efficiency: Considering the high lumen packages required in large production halls in the automotive industry, the energy requirements for lighting systems are particularly hefty and the system efficiency of LED luminaires is therefore especially important. Significant energy savings can be made by using dimmable LED luminaires. Extreme temperatures: While lighting systems are often exposed to very high temperatures in production areas in the food industry, extremely low temperatures are required for the storage of foods in deep-freeze facilities. Products developed specifically for the food industry are designed for extreme conditions like these and can be permanently used in ambient temperatures ranging from –40°C to +50°C. Visual quality inspections: Before foods are packaged, they are normally subjected to a visual inspection to see whether the products comply with freshness and quality requirements. The use of light sources with high colour rendering is

Demanding visual tasks: Demanding detailed tasks, such as working with test samples, require high illuminance and low levels of glare, particularly in laboratories. Disruptive light reflections on glassware can be reduced by using luminaires with a homogeneous light-emitting surface. For particularly tricky visual tasks, general lighting concepts can be optionally supplemented by individually adjustable workplace luminaires. Car parks: Lighting in car parks is used around the clock. A combination of energy efficient LED lighting solutions and corridor-function controls is ideal for keeping operating costs as low as possible. Vertical illuminance plays a crucial role safe parking and exiting, as well as safely crossing driving areas. Due to the low mounting heights in car parks, light distribution should be as wide as possible for even illumination. A slight indirect share creates a pleasant spatial atmosphere. Qual ity inspection: The work of a quality inspector requires the utmost concentration. Unevenness and minute errors have to be detected and corrected immediately. Ideal lighting conditions are an essential requirement for this work, providing employees with the best possible support for complex activities. Workplace lighting is usually used to supplement general lighting. This can be adapted for special requirements such as increased illuminance or separated light colours. Agriculture : Stubborn dirt and ammonia emissions associated with animal husbandry and the storage of manure are a major issue for farms. Luminaires with extra protection and particular materials are therefore ideal, especially PMMA, which is resistant against gases and aggressive cleaning agents commonly found in barns. An energy-saving LED lighting solution soon pays off due to the large size of the halls and the long operating hours. LED industrial lighting offers solutions for the gamut of lighting challenges mentioned above. In addition to the efficiency and low maintenance of LED lighting, intelligent light management is helping to enhance the workforce’s occupational safety, productivity, focus and overall well-being. Lighting constitutes nearly 10 per cent of the total cost of setting up a manufacturing unit and its subsequent running costs. Selecting the right products can cut costs considerably. www.zumtobel.com

Left: Flexible lighting systems support resiliency in the workplace by providing a com- fortable, productive, engaging work en- vironment that can change and adapt over time. Right: Lighting is functional and essential, but it also has the power to be motivating, engaging, and to create a connection to nature.

How smart lighting helps define the resilient workspace

Offices look very different from what they did just two years ago, but the traditional workplace was changing long before that.

B efore the pandemic, open office plans were ceding to flexible office plans; the workday itself was becoming more fluid as employees moved between remote work and onsite work; global markets demanded innovative ways to communicate when travel was too cumbersome or expensive. Today, more than ever, a successful workplace needs to be resilient – it has to be flexible and nimble enough to handle anticipated and unanticipated change, able to support employee wellbeing, and poised to continue to add value over time. Flexible, smart lighting systems are essential to resilience. And while the coronavirus pandemic has helped pinpoint the focus on flexible lighting, specifiers and manufacturers were already implementing solutions that could respond to whatever the future brought while being human centric enough to provide a comfortable, productive, engaging work environment. Wireless systems enable that flexibility. They are simpler and easier to design, but also dynamic, more powerful, and more responsive than many wired options. Lighting and shading solutions can enhance comfort and foster a connection to the outdoors. State-of-the-art controls help balance the human need for interaction with social distancing recommendations by offering personalised or touchless control options for employees and occupants. And smart solutions contribute to more efficient space management by helping to identify and evaluate occupancy patterns and work in concert with scheduling and room-reservation software.

Flexible lighting: Able to address today’s realities and tomorrow’s challenges Even in an ideal world, lighting requirements change as projects progress. To meet aggressive timelines and demanding budgets lighting control solutions have to be easier to design, require fewer up-front details, and be able to adapt quickly to accommodate changes over time. The fewer limitations a system places on designers, and ultimately their clients, the better. For lighting designers, it can be more efficient to rely on a go-to system that is equally at home in both small spaces and large spaces, retrofit and new construction, and with whatever fixtures and light sources they select. Wireless, scalable solutions can offer all these advantages, and more – they can pivot quickly in the face of changing space layouts, can be easily reprogrammed or rezoned to align with social distancing guidelines, and with wireless it is easy to add controls at any time wherever and whenever they are needed. Wireless solutions will play an even bigger role moving forward since they can be installed and programmed quickly with no new wiring – this is especially important in retrofits. System controls such as occupancy sensors, daylight sensors, and timeclocks are not revolutionary, but they are increasingly important to meet code, and to provide the right lighting, at the right time. Again, wireless systems offer reassurance that when the client wants additional control locations or needs to add wireless sensors for touchless control, the designer can deliver without having to reinvent the
