Visit www.lightingindesignmagazine.co.za Gregg These two events allowed attendees to delve into the latest technological innova- tions, leading lighting strategies, and business models and increased their knowledge on the potential lighting of the future presents. Hearing the presentations and wealth of knowledge shared at the seminars, reminded me of another apt quote by physicist William Pollard, “Learning and innovation go hand in hand. The arrogance of success is to think that what you did yesterday will be sufficient tomorrow”. M ahatma Gandhi said, “Live as if you were to die tomorrow. Learn as if you were to live forever.” This quote applies to both life and the lighting industry; with change the only constant, keeping abreast of the latest innovations, findings and developments is imperative. In recent months, lighting designers, manufacturers and electrical engineers have been fortunate enough to have been given the opportunity to broaden their horizons and knowledge at a smart street lightingmasterclass and BEKA Schréder’s Lightability Seminars. BEKA Schréder hosted its first of a series of seminars that will be held in all the major centres of South Africa. Held in Pretoria, attendees were updated on LED technology, current and future trends, thermal management, mid-power vs. high-power vs. CSP technology LEDs, tunable white, amongst other topics. A new luminance meter and its revolutionary way of measuring luminance levels onsite was also introduced. BEKA Schréder’s rollout of its Lightability Seminars gives at- tendees the chance not only to firm up their foundations of lighting principles, but also to expand their knowledge of LED lighting trends and technologies. In August, EmpireTraining hosted an interactive two day master class facilitated by international and local achievers with practical implementation experience in smart street lighting and controls in Sandton.The workshop looked at utilising avail- able technology to power and effectively manage resources to support the smart infrastructure that we as society use to power everything from smart phones to communication networks. Vicent Mbonye, Information Systems: University of KwaZulu-Natal, opened the event with the topic Smart and Connected Transportation . His presentation con- sidered a number of case studies, including street lighting projects in South Africa, PLANet intelligent street lighting in Palmerston, Australia, street lighting in the city of Los Angeles and the Akropolis Shopping Centre. Clayton Mclean, a Renewables and Social Entrepreneur discussed LED light- ing and energy efficiency before Justin Harmond, the Georgia Power Operations Manager of Lighting & Smart Services, gave an international view on smart lighting, business models, and light technology as well as monetisation with Small Cells and the potential of street poles. The first day concluded with a presentation by Raja Moudgil, Philips Lighting Country Leader, Southern Africa & Ghana. The second day saw Marnus Marais, Lighting Expert at the BE Group kick off proceedings with a talk entitled Embracing Networks: Smart Lighting for Smart Cities , after which Hendrik Vermeulen, Regional Manager at BEKA-Schréder spoke on how road safety is being compromised by outdated lightning technology and what can be done.

Creative use of lighting in an industrial environment

A close working relationship between architect and electrical engineer has resulted in an efficient and innovative lighting solution for a cold storage facility in Cape Town. T he Southern African Fruit Termi- nals (SAFT) Group of companies was established in 1999 as a cold storage solution for fruit and other per- ishable industries. Making its debut in CapeTown, SAFT soon spread its wings offering its services in other parts of the country. “SAFT Atlantic in theWestern Cape is SAFT’s flagship building and one of the first buildings at Atlantic Hills Business Park,“ says architect Joe de Villiers of Joe deVilliers Architects. “It is in a prominent position in the business park, so the building needed to make a good impression.” While the intricacies of the cold store/warehouse were the responsibil- ity of the team of engineers and other consultants, Joe de Villiers Architects’ brief was to ensure that the overall proj- ect was aesthetically pleasing within the constraints of an industrial building type, and a limited budget. As such, Joe deVilliers Architects was responsible for the design of the office building, staff facilities and gatehouse. “The lighting throughout the facility is entirely LED, as not only is it the most efficient in terms of light output and lifespan, but is also quite easily adapted to function in extreme environments,” notes Dominic Bright, of Converge Con- sulting, the electrical engineers on the project. “Being a cold store, specialised light fittings are required to provide nec- essary lighting levels within the facility

and perform not only in sub-zero tem- perature conditions, but also in areas of very high humidity.” All the lighting throughout the facility is controlled via occupancy sensors which control the output of the fittings by dimming down or ramping up to full output based on detection of people in the vicinity. This reduces the overall lighting consumption by up to 70%. As the facility operates 24/7, the external yard lighting plays an important part of the functionality of the facility, and the external lighting design had to allow for night-time use without lighting spill or glare. Each different area’s requirement informed the specification of the light- ing. By analysing the primary design parameters of light levels (lux), light fit- ting mounting heights, equipment and racking layouts, environment (operating temperature and humidity) and surface reflectance (walls, floor and ceiling), Converge Consulting developed a light- ing schedule of fittings with different light outputs, beam angles and enclo- sures to suit. “By designing according to fixed layouts we were able to ensure that the necessary lux levels were al- ways achieved by changing the output and beam angles of the light fittings to direct the light as required,” says Bright. In the cold storage areas a com- bination of linear LED high bays (with different beam angles) and low tem- perature, waterproof LED luminaires was installed.The offices were lit using recessed LED panels in the suspended ceilings with 6W and 14W LED down- lights in bulkheads and skimmed ceil- ings. Decorative suspended LED strip lighting at different angles was installed at reception and in the boardroom. The external yard lighting was also important and floodlights with cut-off diffusers were installed to limit glare and lighting spill from the facility.

light other sections, de Villiers notes there was no specific call for such a feature. “But, we came up with the concept for the lighting as a means to create a striking effect without adding too much cost using backlit polycarbon- ate sheeting. Internally, we specified hanging LED lights arranged at different angles, which repeat the angles used in the stepped sheeting (cladding) on the façade. Up-down wall lights on the exterior also highlight the splashes of yellow paint, a nod to SAFT’s logo and corporate identity,” he says. The play of light is a highlight of the structure – be it sunlight during the day or the LED lighting at night – the fact that the sheeting is articulated by means of stepped sheeting in two different colours (light grey and dark grey) means that the sunlight plays on the façade during the day and is up lit at night with powerful LED strip light- ing washes to accentuate the lighter grey recessed sheeting. Elsewhere, a canopy over the row of loading bays with a polycarbonate fascia along the front, is also backlit. “The challenge with lighting, and particularly façade lighting, is to achieve the correct lux levels to enhance the features of a building, and not to over- light,” says Bright. “Any structure can be lit up, the important role we have as designers is to ensure that we do this either by using light as the feature (such as lines of light on the façade) or by highlighting certain elements of a building. At SAFT it was important to conceal the façade lighting and rather to highlight the articulation of the façade.”

LiD Q3 - 2019

De Villiers notes that the detailing of the stepped sheeting and the backlit polycarbonate cladding was a bit tricky, as was sourcing LED strip lights that would be strong enough to wash up the façade, which is, in some places, up to 14 m high). “We had great help from the electrical engineers in this regard and mock-ups were installed on site at an early stage for our approval. The structural engineers were very accommodating and assisted with the detailing of different brackets to mount the stepped sheeting,” he says. The importance of lighting “Lighting is the most important design tool we used to elevate the building from ‘just another industrial building’ to something noteworthy,” says deVilliers. “Apart from the important functional requirements of lighting, we think the creative use of lighting is often neglect- ed in industrial environments. Many industrial developments are in promi- nent locations along our highways, and we think it is important for these not to be neglected.” Internally, as the facility makes use of high racking elements, it was extremely important to ensure that the cold store lighting had as little glare as possible so the forklift operators can look up at the racks without their vision being affected. “We are glad to say that our vision has become a reality,” says de Villiers in conclusion. “The façade lighting is drawing a lot of attention and the building is a talking point in the industry in Cape Town; something that was achieved with minimal additional cost.”

Lighting plays crucial role in human-centric office design

The new AAA grade head office for Cube Route Logistics is located within the Boundary Park Industrial Park, and was carefully designed with the wellbeing of both people and animals in mind.

T he prominent Malibongwe Drive frontage created an opportunity for Architects Of Justice (AOJ) to design a landmark building that would be impressive to onlookers passing by. The notable, non-conventional façade features an array of off-shutter concrete columns set around the building, over an envelope with coloured wall panels spaced between the glass curtain walls. Described by the architects as an ‘ultramodern structure’, their vision was to present a raw con- crete exoskeleton, filled by a pristine, smooth envelope containing a modern, clean and sleek interior.The juxtapositions of raw and smooth, dull and bright make interesting, striking and memo- rable architecture.

Having designed the shell of the 1000 square metre office block with warehousing and e-Pet store facility measuring approximately 9000 square metres, AOJ then set about creating an interior which harmonises with the striking façade. “With a very modern exterior, we wanted to create con- temporary interiors as well, which complement the geometry of the building,” says Mike Rassmann. Owing to the step backs in the façade, the office building has a geometric formwhich created many angles to work with. “We provided spaces for staff to sit outside on a large terrace, and balconies which overlook the yard areas and the activity be- low. Internally, the spaces complement the lines and angles of the façade, and we used different

they are essentially the same company, they needed to appear as separate for product branding. Part of the solutionwas splitting the two by floor and aligning the corporate identity accordingly.” The lighting design was critical to the interior, especially in the spaces where the architects were able to embellish a little more, such as the reception spaces, meeting rooms and in the large communal kitchen area in which the staff can congregate, eat or even work in a more relaxed environment. “We started with a high end design, and one of the big challenges was trimming that design back to budget whilst still maintaining the same kind of appearance. A hierarchy of the spaces can be seen in the chosen finishes, most notably in terms of the lighting. This included picking the right light fittings, surfacemount- ing them instead of cutting into the ceilings and recessing them, without going completely overboard with bulkheads. We used several pendant lights, hung at different heights, and picked the fittings very carefully to complement the exterior, thus many of the fittings that were picked have a geometric and angular concrete finish,” says Rassmann. The main lighting directive was reducing en- ergy consumption, thus the use of LEDs, yet at the same time, the lighting concept was informed by the striking lines across the façade. “This we echoed in the lighting design with long, thin LED linears,” Rassmann notes. Lighting was limited on the façade to security uplighters, as the designers wanted the building to ‘glow’ from within through the double volume glass entrance. Lighting chal- lenges experienced on the project included the fact that time and cost constraints dictated that much of the lighting had to be surface mounted rather than recessed, as well as getting staff to understand and use the motion activated lights correctly. Glass played a large part in the interior due to the high ceiling volumes of the space. “We had to get the balance right between glass and dry wall partitioning,” explains Lacovig. “With glass costing close on seven times as much as drywall partition- ing, we raised certain portions of the drywall parti- tioning to hide the desks and the assorted cabling,

finishes, such as striped, colourful carpets mixed with more muted tones so it is not too heavy on the eye,” he says. The architects brought through a fair amount of patterning to follow the diagonal geometries of the façade, working with different carpet colours to create visual interest. “The advantage of having one company dealing with both, is that you have a better sense of under- standing the conceptual design of the building, and can bring that thread right through into the interior which gives you a better product at the end of the day,” says Rassmann.The interior doesn’t disregard the exterior, and vice versa. “The way interior and exterior intersect is very conscious,” explains Alessio Lacovig. “We haven’t hidden the concrete structure within the building; you can see how the ceiling edges have been stepped back to expose the underside of the concrete slab and you see the concrete beams perforating the ceiling and glass façade to intersect the columns and support the floor slab, making the expression of the structure visible from the office interior. Rassmann notes that the project presented an interesting scenario, as there are two companies that run internally – the logistics company for pet products and an e-Pet store.This new head office is the amal- gamation of two Johannesburg operations, with the third still located in Durban. “We had to incorporate the two companieswithin the one building, andwhile

but then raised the glass above desk height. This allowed us to offset the cost of glass, but at the same time strategically position it in the interior to allow a maximum ingress of natural light. The warehouse portion of the logistics facility had to be well laid out to accommodate the multiple daily deliveries via a fleet of 30 trucks which travel to approximately 800 outlets in South Africa. An array of drive-in bays, a large covered side curtain loading area and dock-leveller loading bays offer a variety of vehicles the space required for an efficient operation. “While translucent sheeting in warehouses is stan- dard,” says Lacovig, “we created a natural light band at around 9 m high to keep the translucent sheeting above the racking level to supplement the high bay LED lightingTo allow even more natural light into the facility we introduced a monitor at the centre of the roof design and included a newly patented system, one of the first to be installed, featuring a translucent smoke vent which, unlike conventional solid louvres, will let light in and also flap open completely when smoke needs to be extracted.” Froma sustainable point-of-view, general sustain- able practices were followed. Correct orientation and the use of double glazing on the façade – coupled with correct proportioning of this façade – ensures a passive control of natural light entering the building, as well as the thermal temperature gains and losses, improving energy efficiency. In addition, the façade’s design assists in reducing the noise from the busy road alongside the office. “We kept the size of the

west façade small, thereby limiting exposure to the harsh afternoon sun and have a smaller ratio of glass to solid walls,” states Lacovig. “ Roughly 50-60 people will be employed in the main office space, and the architects note that the business almost has the feel of a large family business. “Very early on in the process we were informed that the old office had a tiny kitchen space, but that was where all the office staff interacted. In this new office, we ensured that the staff have enough space to gather, work in a café-style area and even cook meals together. Cube Route’s head office is a busy yet relaxed environment where people are encouraged to bring their pets to work, so it really was a project where we could explore the boundaries of themodernworkspace,” says Lacovig. The interiors were designed to be as human- centric as possible with abundant natural light, high volumes and extra colour, without coming across as being overpowering and garish. “From the shape of the façade, it gives staff an interesting interior space, not your conventional four wall box. That in itself changes the quality of the space and the perception of the space you are working in, making it a building which is exciting to be in,” states Lacovig. This emphasis on aesthetic appeal – coupled with a human-centric design approach – has re- sulted in a unique, eye-catching building which devi- ates from the norm of a ‘one-size fits all’ approach to head office design.

Natural light, LEDs combine in lighting design for Oracle SA head office

Design-and-build specialist Trend Group had to adhere to strict lighting and acoustic requirements at the new headquarters for Oracle South Africa in Woodmead Office Park.

T he brief was to deliver a purpose-built new building that rationalised the enterprise soft- ware giant’s operational requirements, opti- mising its space usage as opposed to downsizing. The client also had strict lux requirements for the different areas of the fit-out. These ranged from operational (white light) to ambient conditions (wall lights) in the collaborative spaces and other private and breakaway areas. The lighting installation is also future-proofed in that it is ready to be integrated into the BuildingManagement

System (BMS), which is yet to be implemented. Trend carried out a lux calculation for each floor to ensure it adhered to all client requirements. Pendants were incorporated, especially in the canteen, and served the dual purpose of lighting and providing acoustic properties. All the lighting was LED for maximum energy-efficiency, including feature lighting in the form of LED strip lighting. “The lighting intent was to supplement any shortfall from the natural lighting. There is a lot of glazing on the building, which admits a great deal of

We have created an inclusive space that will encourage innovation, foster learning and inspire organisations to achieve more,” Patel says.The project has officially submit- ted its documentation for a five Green Star rating from the Green Building Council of South Africa. Genstar Lighting was requested to produce LED lighting solutions, for two specific areas, base- ment parking lighting and peripheral downlighters for office use. “The selected LED downlights was the Robus 9 W LED Taylor, equipped with a CCT3 selectable internal switch,” notes Genstar Lighting’s Darryl Greer. “This allowed the client to vary the colour selection from 3000 K through to 6500 K, depending on the area of installation, for example, 4000 K was used in the general areas.” For the park- ing lighting, the main criteria were to offer energy efficiency, as well as ease of maintenance.

natural light, so it was just a matter of determining where this infiltrated to the required level,” Trend Group Technical Designer Nicola Bridge explains. Passive infrared sensors control the lighting, switching on and off automatically whenever there are occupants in an area. Automatic blinds were installed on the ground floor, front-of-house, and canteen areas, with man- ual blinds on the upper levels. “We collaborated closely with RWPTaemane as the lighting engineer. We designed the lighting intent, and they took it onboard to make it compliant and energy-sufficient; ensuring it meets all the local requirements and building standards. “It all links back to comfort, and ensuring people are comfortable within the workspace, without suffering eye strain or being over-stimulated as a result of the lighting,” Bridge highlights. “Digital transformation is on the rise in South Africa and with an unmatched portfolio of solutions and sup- port infrastructure, Oracle is poised to lead the country’s digital revolution,” says Niral Patel, MD and technology leader at Oracle South Africa. “The new office facility in Johannesburg is our latest investment and solid evidence of our commitment to South Africa.

A work of art

Inhouse were asked to provide a lighting schematic design solution suitable to an upmarket art gallery for a private art collector. The design had to allow for an art exhibition-style lighting scheme where the artwork becomes the focal point.

F or the Gallery at House 351 in a private resi- dence in Fresnaye, CapeTown, the designers at Inhouse had to focus their attention on concealed, mood lighting and directional lighting to provide focus to the art pieces. “While it was important to highlight the artwork, it was equally important not to get hotspots on the walls and to have consistent, even lighting,” notes Inhouse Creative Director, Aidan Hart. The art lighting required flexibility to accom- modate art being moved around, as well as fo- cused light sources with optimum beam control to mitigate glare. The lighting had to be the right

temperature for the art pieces, and it had to work with the modern design of the white space. The temperature of the lighting also played a big role in making sure that the lighting doesn’t damage or fade the art pieces. A high colour rendering spec of the light source was critical to bring out the true colours and textures of the art. “To make the art stand out we opted for 3000 K colour rating, still on the warm light spectrum but more crisp than your typical residential lighting,” he says. “We also had to allow for a lighting scheme suitable for functions, which required more ambient lighting to enhance visual depth and spatial flow through the trendy

space.The lighting scenes are controlled and man- aged by a home automation system.”

Lighting specific spaces Three areas make up the gallery: the space where the artwork is on display; a staircase leading guests into the space; and a bar area with a scullery and bathroom. Each area required Inhouse to focus on specific lighting styles. Staircases require a safety level of lighting to provide safe passage, but you also want to create a sense of flow. This was done by curve lighting elements that run down either side of the ceil- ing, providing wall washing lights onto specific artworks. The feature staircase incorporated LED lights in the curved timber handrail as well as the stairs tread overhangs, to give a warm, soft glow. The overall lighting concept behind the gallery space was a concealed black ceiling void into which art quality spotlights were installed to allow for maximum flexibility when lighting artworks that can change location and come in different sizes. The art required spotlights which were positioned in recessed tracks, to move or tilt as needed.The small

15

LiD Q3 - 2019

entertainment bar area adjacent to the art gallery was lit in a moody warm 2600 K light level, and in- cluded accent LED lights in the joinery.This allowed for a sense of intimacy and enhanced the usability of the space. One big challenge experienced by the design team was the high ceilings. “This may sound con- tradictory, but lighting design on high level ceilings requires consideration so as not to oversaturate the walls and floors, while providing maximum exposure to the artwork,” says Hart. “We were also limited in ceiling void space, and a careful selection of light fittings was required to ensure that the cor- rect fitting would provide both the necessary light- ing and fit into the void space above the ceiling.” It was also a challenge installing the LED lighting in the timber curved handrail. This was overcome using a new product from Martin Doller, which is an LED light in a flexible track. “Inhouse’s projects consider lighting to be a critical aspect in the final product. The success of these projects is in part determined by the lighting design, and we focus our attention on creating suc- cessful lighting solutions for our clientele,” says Hart. “Similar to other Inhouse projects, the lighting has played a crucial role with regards to the final product of the project. It was of the utmost importance that therewas harmony between various design aspects and this harmony has been created in the gallery. In addition to its practical purpose, the lighting in the gallery

enhanced the space by drawing attention to the art, and the colour of the lighting provided a general sense of moodiness at the bar area.”

Light fittings used • Focal point lighting/art lighting: Focused directional narrow beam light sources on adjustable spots on tracks for maximum flexibility • Ambient lighting: Created through indirect cove and joinery lighting with hidden recessed LED strip lighting. The black recessed boxes allows for a seamless modern lighting solution and the black recessed troughs mirror the black painted shadow lines along the floor finish. The following products were installed: • A recessed single downlighter (black) • 84 Single spot light tracks • One feature light • Three double spot light surface • 73 Three-phase track systems • 76 x 7,5 W, GU10, CRI95, 3000 K dimmable lights • 15 x 5 W, GU10, CRI80, 3000 K, dimmable, 60 degree beam angle A crucial aspect of the lighting in this project was the colour of the lighting. Lighting colour is defined by the temperature at which the light is omitted from the light fitting and is incredibly important to any environment. A very warm fitting (down in the 2400 K range), which gives a cool white light, will change the way the final product is perceived by the human eye. This includes materials and textures you wish to enhance with lighting. The colour of the light fitting lenses is also important to consider when lighting specific wall features. Sometimes a colour filter will enhance a wall feature to maximum effect; this can all be done very subtly and without direct knowledge of the observer, but to great success in the final product.

Promoting a unique identity after dark

The external lighting strategy of the new Park Square development, devised by Arup, embraces the latest in lighting concepts.

T he R1bn mixed-use office and retail develop- ment situated in the heart of Umhlanga New Town Centre in KwaZulu-Natal opened in late 2018. Arup provided integrated lighting design for the external lighting strategy of the Park Square Development. The company progressed the lighting concept, developed in conjunction with MAP Archi- tects, by looking at each external lighting element in detail with a view to creating a high-quality night-time environment. “Park Square showcases how various street- and-landscapes as well as architectural features can transform public environments through their careful integration of light,” explains Shikar Takurpersad, Associate at Arup and electrical lead on the project. “That visitors and tenants experience a quality experi- ence in the public spaces was a key consideration in the design for the external lighting for Park Square.” Integrated lighting The external lighting design had the following objectives: • To create an appropriate ambience and mood. • To promote legibility through the illumination of features including edges, nodes, paths and the enhancement of key vistas.

• To promote a unique identity for the area ‘after dark’. • To provide for safety, security, orientation and assists way finding. • To provide sustainable lighting solutions that minimise energy use. “The intention was always for the lighting to guide movement – people are attracted to the brightest part of a lit scene,” expands Takurpersad. “The dy- namic lighting components create visual interest that encourages people to linger in the space rather than simply pass through.” The lighting design combined well illuminated focal points and destinations. Light modulated the architecture, creating visual interest. This was bal- anced with ensuring that a high quality lit environ- ment was achieved by using a limited light colour temperature palette of white light, together with a range of light intensities, giving definition to the different areas and functions of the site. Enhancing the façade The intention for the façade was that the lighting will vary, respond to, and reinforce the layers of the building and activity behind accentuating the

‘wrapping’ nature of the vertical screen element. Illuminating these vertical fins on the park facing façade screen highlighted the ‘layered’ nature of the building and accentuated the lightness of the glass office ‘blocks’.The dynamic digital control for this lighting component created ‘moving lines’ of light and resulted in a lively animated effect when viewed from the adjacent Chris Saunders Park.This illumination was achieved through a complex Digital Multiplex (DMX) control system which required an extensive testing and commissioning process with specialist sub-contractors. Lighting the square The public square area is in effect a ‘void’ space created by the collection of ‘blocks’ forming the development. In order to further enhance these blocks and voids after dusk, the lighting strategy for the square took inspiration from the built form with different layers and volumes of light including recessed, flush and extruded forms. The perimeter glow from the retail units was supplemented by lit elements within the piazza such as up-lit trees providing visual interest in the vertical plane, integrated bench lighting and lit floor tiles and restaurant tables. Thewrapping façade screen flows into the piazza forming a ‘slatted’ backdrop to the space.The oppor- tunity was again taken to digitally animate the linear light elements in this façade screen creating various light scenes and visual intrigue for users of the space.

The tall form of a central stair tower with ad- joining amphitheatre creates the largest ‘block’ of the hierarchy within the square. Just as a fountain or sculpture can be the centrepiece of an external space, this lit ‘volume’ has become a key focus after dark with the incorporation of feature colour changing lighting. Sustainability in design Park Square was awarded a 4-star Design rating by the Green Building Council of South Africa (GBCSA). Nedport has subsequently committed to targeting a more ambitious 5-star As-Built rat- ing. Lighting plays a critical role in achieving these objectives. Preliminary calculations show that project will achieve a 36% reduction in energy consumption over the Green Star benchmark. Contributing to this is the fact that lighting design to the internal office spaces was in accordance with green star best practice principles. Both passive and active strategies are being implemented to achieve this target. Good daylight levels, coupled with the use of occupancy sensors for switching, saving energy when unused have been applied; lighting zones in the office space will not exceed 100 m 2 thereby al- lowing light for occupied spaces only; LED sources have been utilised for additional energy efficien- cies – these are all factors that ensure that energy efficiencies are optimised.

Lighting in the urban age More than half the world’s population currently lives in cities and it is estimated that this figure will be 75% by the year 2050. Those involved in the design, governance and implementation of cities are increasingly required to develop innovative solutions to respond to today’s exponential urbanism. The life of our cities after dark is only one element of this challenge.

I n simple terms, we light our cities so its inhabit- ants can perform a variety of functions by day and night. Howwe do this and, in particular, how suc- cessfully we do this, requires an equally innovative and informed design approach. Arup investigated an integrated approach for sustainable urban lighting masterplanning in response to a perceived gap in the current knowledge of the link between urban design and lighting engineering. The majority of urban lighting approaches either lean towards urban strategies or towards engineering solutions. Urban strategies are able to transform a space into a place unlocking the potential of the urban environment, but lack the technical knowledge of how to do so. Engineering solutions are technically sound, and comply with codes and regulations; however, they often lack the design sensitivity and understanding of the urban context. As a firm of multidisciplinary designers and engineers, Arup proposes that the integration of these two very different design methodologies is possible by first understanding the following four key ‘drivers of change’ currently shaping the built environment: What are the key issues cities face today? At pres- ent, 50% of the world’s population resides in urban areas.This number is likely to increase, although the distribution of population and nature of the increase is not the same everywhere. All cities, regardless of their pace of growth or development, are facing similar issues of economic stability, social cohesion and climate change. All three factors need to be considered when working at an urban scale, whether public space or all-encompassing masterplan. In China, India, Africa and Latin America, urban populations are exploding and cities are growing exponentially. At the same time, many developed cities are shrink- Drivers of change 1 – Urbanisation

ing and being dramatically restructured as a result of shifting economic bases and new patterns of migration. With investment in urban real estate, infrastructure and renovation becoming the driving force behind economic growth, the physical and social landscapes of the city are changing at an astonishing rate. What this means for lighting design, and in particular urban lighting, is that all cities are not alike, nor should they be. In addition to respecting and enhancing the local culture and local identities, it is fundamental to acknowledge that the govern- mental structures are different, levels of crime vary, investments in ‘green strategies’ are unique, and the demands on the population, whether increasing or decreasing, are also very different. Different design responses are required for different cities. A city in England that is fighting to bring people into the town centre has differ- ent needs from a city in China simply struggling to cope with urban sprawl or a series of ‘urban centres’. 2 – Policy and economics Current international and national policies are calling for the reduction of carbon emissions and local municipalities in the current economic climate are facing reduced expenditure budgets. Lighting plays only a small part, but more and more regional planning documents and initiatives are focused on energy, the environment, and climate change. Lighting designers need to be aware of lo- cal policies, understand the current debates and discussions, and also be in a position to influence policies that directly influence lighting. The Urban Age research project in 2009 indicated the vary- ing degree to which countries are funding ‘green initiatives’, which have a profound impact on the work that we do. Not surprisingly, South Korea, the EU, and China are leading the way in terms of

the percentage of financial support. This indicates where green stimulus is in place, but it also high- lights opportunities for other countries to bolster their stimulus packages. Other key relevant policy initiatives include: Kyoto protocol & Copenhagen 15: The most well-known initiative to reduce carbon emissions globally is the Kyoto Agreement, which was later fol- lowed by the Copenhagen 15, and is addressed each year, in the hope of a binding, global agreement. The C40 initiative: The C40, the Cities Climate Leadership Group, is an international initiative which helps cities committed to tackling climate change mitigation and adaptation. Ban of the incandescent light bulb: One of the most powerful movements in the European Union is the banning of high-wattage incandescent light sources.This forces change and has a powerful im- pact on the residential lighting market in particular. LUCI and the charter on urban lighting: The Lighting and Urban Community International recently published a Charter on Urban Lighting where more than 30 worldwide cities have signed up to principles for both ‘Sustainable Cities’ and ‘Sustainable Light’. For more information, visit www.luci.org. 3 – Energy and the environment Lighting is a visible element of expending energy and as such is often a key target of energy reduc- tion schemes. An interesting comparison lies be- tween the amount of light pollution compared to the amount of overall carbon emissions. As can be expected, the correlation is very close. What is remarkable, though, is the comparisons arising from the Urban Age conference series on the correlation between flood risks and carbon emis- sions. According to the conference data, the cities emitting the most CO 2 do not necessarily bear the same level of risk when it comes to flooding, or those emitting less CO 2 annually. This fact reveals that the greatest ‘offenders’ in CO 2 emissions affect the flooding of areas that have less of an energy impact. Shanghai and Mexico City are the only heavily polluting cities that are also largely prone to flooding. Interestingly, lighting has often been seen as a source of progress for developing nations but we should see this in terms of lighting quality rather than quantity. However, as important as it might be

in reducing the level of carbon emis- sions and amount of light pollution in de- veloped countries, it is even more important to create new patterns of development and consider city lighting holistically. Urban lighting planning or site wide strategies should include references and ideas to the following: – Minimising light pollu- tion. – Setting out environ- mental zoning stan- dards. – Addressing the re- cycling of hazardous materials found in light sources. – Minimising energy con- sumption. – Considering life cycle cost- ing analyses. – Considering the responsivity to light of local ecology. 4 –Technology Lighting equipment, lighting control, and renewable technology advance at a rapid pace. This knowledge is critical when providing strategic

advice to cities, planners and architects. In addition, the current model for cities is simply not working as resources are not being used efficiently. Technol- ogy has the power to drive the changes to- wards designing cities and systems of power in a remarkably efficient way. While the developed

countries are struggling to find ways to reduce en- ergy expenditure and their dependence on fossil fuels, the developing countries, without such extensive services networks, are making sustainable leaps and bounds

Shouldn’t it be our aim that all lighting installations be powered solely by renewable sources?Technology can be utilised in creative ways to bring people together. In Kenya perhaps this means illuminating a village shop, while in Europe it could be an interactive media facade that allows social interaction and enlivens a deprived urban zone at night.

It was discovered that artificial lighting allowed people in the community to interact after dark; children were able to study and do their homework at night, thereby improving their future educational potential. Sometimes a different but simple ap- proach is required to make a real difference and

Lighting in Design asked Grant Combrink, marketing manager at BEKA Schréder about urban lighting in the South African context.

LiD: What socioeconomic impacts can im- proved urban/street lighting offer? GC: Urban and residential street lighting must create public realms that let people interact with each other and the environment. Proper urban lighting can improve the following as- pects: • Safety. LiD: How does modern urban/street lighting take the environment into consideration? GC: The advantages of LED lighting include: • Energy efficient. • Long product lifetime therefore non-toxic, i.e. mercury, replacement parts. • Low glare. • Light only when and where needed. • Control systems. LiD: What challenges are faced, especially in South Africa, when it comes to urban/street lighting? GC: Challenges include, low performance and specification on some low-quality imported products; not using the correct luminaire, • Energy and monetary savings. • Well-being (colour temperature).

distribution or optic for the application; vandal- ism or theft; and a slow change over to LED technology in certain areas. LiD: What role do you see smart lighting play- ing in the future of urban/street lighting? GC: Full asset management by monitoring every single lighting point and knowing its detailed configuration or status as well as instantaneous event-reaction of lighting points in mesh network. Connectivity with wireless or wired sensor on standard and open protocols; providing a city with free WiFi hotspots is advantageous both for residents and tourists, who would enjoy an internet connection without data woes, and for the local economy, which would largely benefit from increased levels of trade and tourism. LED lighting is helping transform mobile networks and providing the infrastructure for scalable Smart City development. The world is witnessing a rapid expansion of mobile broadband use. The most recent studies pre- dict global mobile data usage will double by the end of 2020, as more people want access to information and applications on the move.

This is combined with increased demand for coverage and capacity of mobile networks. In dense urban areas where space is limited, operators can struggle to increase network sites to cope with the growing demand. To combat this problem, our Shuffle col- umns – the first connected streetlight to be launched on the market – now incorporates small cell technology; improving network coverage for end-users on the street. Street lighting is the one constant pres- ence in every town and city throughout the world. By integrating small cells within the lighting columns, there is no need for ad- ditional street furniture and the collaboration between local authorities and mobile operators can be approved – allowing us all to benefit from the development of truly Smart Cities. Furthermore, energy savings of up to 85% can be achieved with Virtual Power Output from remote monitoring, giving you full control over your energy usage. Multiple dimming scenarios will enable you to have the right light at the right time to ensure safety, while at the same time, a constant light output will extend the lifetime of the fitting. www.beka-schreder.co.za

Tips for lighting a home office With the number of people working flexitime or from home, it is only a matter of time before a lighting designer is asked to light a home office.

Use a desk lamp for task lighting Users will likely use this room to work on a com- puter, file paperwork and sign documents. Tasks such as these are focus-intensive and require a reliable, defined light source. An adjustable desk lamp is ideal for the job so the user can direct the light source exactly where it is needed. If there are multiple workstations in the room then consider a dedicated task light for each. Add a decorative touch Task lighting and ambient lighting are essential for creating a productive workspace but don’t forget to incorporate decorative lighting to add a bit of personality to the room. You may also want to consider highlighting a favourite piece of artwork or photographs on the wall with accent lighting. Don’t overlook natural light Natural light is great for stimulating the senses and increasing productivity, but it can also be a prob- lem. If there is a window in the office, position the computer screen in front of it. Sunlight streaming in from behind will create unwelcome glare.

W hether people work in a home office or a cubicle environment, the character and quality of lighting in the workspace can help increase productivity. Poor lighting can reduce energy, dampen morale, produce eyestrain and headaches, and ultimately impair ability to work effectively. The experts at Eurolux offer their tips for home office lighting: Avoid direct, overhead lighting Working under the direct glare of harsh, overhead lighting is a sure way to discourage productivity in a user. Lamps with shades and floor lamps that shine in an upward direction are great for providing sufficient ambient lighting. They create a soft glow and don’t cast shadows.
