O ver the course of the last few years, an avalanche of transformational change has swept through all industries and societies, globally and within Africa, forever changing the manner in which we communicate, collaborate, learn, play as well as engage with friends, family and colleagues. Although much of this came as a fast-tracked by-product of the coronavirus pandemic, it is fair to say that we were already heading down that road. Now, as many workplaces begin to welcome employees back to the office or campus amid the ongoing pandemic, there are numerous concerns on our minds. How many people are in the building at any given time? Does the office layout allow for social distancing? What areas need extra cleaning attention? The solution: connected lighting. As you will be aware, connected lighting has the ability to bump up its intelligence factor by networking various devices in an Internet of Things (IoT) scheme. Read our article on page 16 to see how connected lighting is being employed in the urban lighting context, and our article on page 18 to read about connected lighting in the retail setting. The buildings of today can too be user centric, allow for immediate flexi bility and have future-proof digitisation concepts and systems installed. This is best achieved by a multi-functional smart building solution, acting as the building’s central nervous system; one that collects data for user-friendly applications, reduces the building’s carbon footprint and delivers cost savings all at the same time. Lighting infrastructure is a requirement for all used spaces, and now the technology exists to use this infrastructure for more than just the illumina tion of a room. Sensors have long been integrated into lighting systems, so why not expand the functionality of said sensors? Research notes that the wellbeing and productivity of building users is mainly influenced by better lighting (+23%), improved ventilation (+11%) and individual temperature control (3%). To combine all three of these well-being metrics into one system makes perfect sense. Sensors tracking occupancy, brightness, and temperature can provide the metrics to control not only the light, but also regulate ventilation and temperature, and do so extremely efficiently. Basic principle suggests that most systems work best if they are kept simple rather than made complicated; therefore, simplicity should be a key goal in design, and unnecessary complexity should be avoided. One simple, reliable system: many positive outcomes. Connected lighting systems allow for the delivery of extraordinary value beyond illumination for companies, employees and the users of spaces. It seems almost negligent not to use connected lighting; yet in a country where tight budgets exist and money talks loudest, it is likely to be a while until we talk about connected lighting as the industry standard.

Elegantly lighting City Centre Within the extraordinary Steyn City Lifestyle Estate is the recently completed first phase of the City Centre’s state-of-the-art apartments and spectacular treed piazzas. Here, residents can enjoy the convenience of apartment living with the luxuries of a seven-star resort. D esigned by Steyn City Architecture Design (SCAD), a joint venture between Nsika Architects, dbm Architects, and Boogert

The ‘villages’ have been built around treed piazzas which, in keeping with Steyn City’s green ethos, have been planted with trees and shrubs all grown from seeds within its on-site nursery. On completion, the city’s piazzas will be lined with several bespoke retailers and restaurants. The de velopment also includes 11 luxurious penthouses, all measuring on average 439 m 2 with features including private lift lobbies, glass garages, and private plunge pools. As part of this exciting project, some of South Africa’s leading interior designers – Stephen Falcke, Lesley Carstens and Silvio Rech, Buzwe Mabuza, Yvonne O’Brien, Amanda Elliott, Bilala Mabuza,

Donald Nxumalo and Ayesha Nobanda – assisted in creating beautiful interiors for six of the apart ments and two of the penthouses, which all speak to City Centre’s setting and context of luxury and convenience. None of the designers was given a brief – in stead, they were asked to create a home for the homeowner they imagine to be the typical City Centre resident. The results are as varied as they are beautiful. From the cosmopolitan jetsetter to the art lover, from the young executive marching her way up the corporate ladder to the couple who appreciates life’s finer pleasures, and ultimately the family seeking a safe haven where they can live their lives to the fullest – all are represented by interiors that explore the full spectrum of ex tremes; from unabashed opulence to understated elegance.

Regent Lighting Solution’s (RLS ) Althea pendants are mounted above the islands in the apartments’ dream kitchens, adding an element of modern sophistication. “These fittings were custom-made,” explains Catherine Feher, RLS Sales Consultant. “The engineers, CKR, and the architects visited our showroom and saw a similar pendant fitting of ours that they wanted to adapt. They sent through drawings of what they were looking for and we made up samples for them, with which they were very happy.” 284 of the 4000 K pendants were supplied, and the modern, contemporary lines complement the high-tech kitchens. In the apartments, high ceilings and doorways are the norm, along with rooms that can comfortably accommodate a king-size bed, with space to spare. Sumptuousness and sophis tication come standard, thanks to Blu line kitchens with integrated Gaggenau kitchen appliances – in fact, the City Centre apartments are home to the largest Gaggenau installation in the world – and boast Kohler fittings throughout. Air conditioning and double glazing ensure comfort in all climates and back-up generators guarantee the lights never go out. Enhancing the outdoor spaces and comple menting the spectacular architecture, a variety of luminaires from RLS were utilised; entering the roadway to the piazzas you are guided by the Quattro 4-way Urban Light Elements. “The 27 Quattro luminaires were supplied with anti-glare baffles and cowls to minimise the glare factor,” explains Feher. “Typically they are mounted at 6 m, however the architects wanted them to be mounted at 4,5 m which was not ideal as the light becomes quite condensed, however, we were able

6

LiD Q2 - 2022

to find a solution to irradicate the glare.” 15 Eos single wall mount luminaires accentuate the structure while providing light down the ramp to the 2000-car super sub-basement. In the basement, RLS’s Nimbus vapour proof luminaires with integrated microwave sensors are used. Unlike most basements that are dark and intimidating, the super-basement is spread out over nine hectares, boasting green lungs, ventila tion, and lots of natural light thanks to its high roof with architectural cut-outs. The facility has been built around 18 lift cores, with ring road access, and all bearing a unique design element (such as mosaic, timber, granite, and marble) to ensure that residents find it easy to navigate their way through the basement to their apartments. The super sub-basement will also feature designated Uber drop-offs at all 18 cores, golf cart parking and electric car charging stations. The piazza courtyards are elegantly illuminat ed by 15 Sliver double luminaires – mounted at 1500 mm in the courtyards and 900 mm elsewhere – and 225 surface-mounted Pathway fittings. Else where, the Linear Mini, in 4000 K, guides residents from one courtyard to another. Furthermore, the Linear 17 x 15, concealed within the staircase railings, gently illuminates the stairs. All exterior lighting was supplied in 3000 K, providing warmth and comfort, enhancing the spaces and providing a sense of comfort and ease. The construction team is currently on site working on Phase 2 of the project, and Feher is looking forward to providing more solutions for the architects. “Getting a project of this size out while in the middle of a pandemic was a challenge; however, it was well specced, well put together, and it has come out beautifully.”

Illuminating an art gallery in Zimbabwe Aberfoyle Art Gallery is a privately owned art gallery and exhibition venue, situated in the lush Honde Valley in Zimbabwe. The intent was to have a modern, multifunctional venue with lighting to suit its needs.

I n 2018, Architectural Planning Studio (APS) was commissioned by Nyangani Renewable Resources to design an Art Gallery on the grounds of Aberfoyle Lodge, Hauna, in the scenic Honde Valley of Zimbabwe. The first thing that the architects considered was the uniqueness of the site. Nestled within a working tea estate, partially surrounded by temperate rainforest, it was para mount that the gallery be unique, and respond to its particular context. Several sites were considered, and eventually one was selected for its incredible views, and its proximity to the existing lodge. To take full advantage of the views, APS oriented the gallery north west towards the golf course, tea terraces, and distant mountains. The gallery brief was to be flexible enough to accommodate a variety of art (including pictures

and sculptures of different sizes), and should be secure enough for high value works, all within a climate-controlled environment that would cater to sensitive works. The architects envisaged the gallery interior as a celebration of light and space, allowing the works of art to be showcased to their best advantage. Internally the curved roof segments are layered, and clerestory windows allow ambient light to flood the gallery space. Large concertina doors open up to a cantilevered balcony which reaches out towards the pond, where sunlight and panoramic views allow contrasting relief from the shaded rainforest. Landscaping complements the gallery building with verdant planting and carefully maintained tree species, drawing attention to the deck and the reflection pond. Programmatically, APS designed

8

LiD Q2 - 2022

the building with flexible and multifunctional spaces in mind, so it could be used both as an Art Gallery as well as a Conference Centre or Wedding Venue for up to 100 people. To this end a catering kitchen was incorporated in the layout, and storage rooms were designed as multi-use meeting/presentation rooms. Mechanical and electrical services are hidden within the building’s basement and routed invisibly up large cavity walls to the necessary rooms. Movable screens and partitions allow artwork to be moved and stored, either to make space for a large open space, or to compartmentalise smaller spaces. The pallet of materials is kept raw and honest, showcasing split face concrete blocks, and timber off-shutter concrete walls, with polished teak floors, skirtings, and architraves. Simple white painted gallery walls allow the interior to showcase the artwork to best effect. Dampening acoustic reverberation within the main hall was achieved through a custom designed ceiling, complete with softwood timber panels, hessian overlay and sound/heat absorbing

insulation above. Lead architect, Geoff Fox, notes that while there was no specific lighting brief for the project, the design brief centred around doing whatever necessary to be able to exhibit high value artwork in a climate controlled environment. “As architects, we suggested an emphasis on multi-functionality and adaptability to enhance the building’s use. For this reason, the main gallery space was to be lit with track lights, which, as much as possible, did not detract from the unique vaulted/arched ceiling and voluminous space, and which at the same time emphasised the ceiling at night with uplighting,” he says. Nulty – a UK-based lighting specialist – worked on the original concept design for the lighting, much of which was implemented by APS. Fox notes that the directional spots on the track lighting were chosen for flexibility and purpose lighting of artworks/sculptures. “The

track-mounted linears providing general lighting within the main gallery. All these elements are individually controlled by the intelligent daliTECH Omega, offering the best lighting levels for any event. The passages also house suspended track lighting allowing for a future permanent exhibition to be housed on these walls, while spot lights were also used to emphasise the pond below the gallery. The ambient lighting for the veranda encourages spill out-gatherings around food and drinks, without obstructing from the main feature – the panoramic views. “The pendants, complete with low watt warm light bulbs were a good idea on paper. However, we had to work with Regent Lighting Solutions to develop a bespoke solution that provided rigidity to the hanging elements and allowed them to be fixed against the wind, and each unique angle, depending on the curve of

purpose of the uplighting on the track lighting was to accentuate the roof/ceiling, and to provide an ambient atmosphere for parties and weddings. Furthermore, all lighting in the main gallery is dimmable, and each track can be switched on or off and dimmed individually.” Check Point Consulting worked with Regent Lighting Solutions on a modular track lighting system that boasts appeal and flexibility. The A-Line lighting system was the perfect solution as this system incorporated the galley spotlights to highlight artwork along with

the I-beam support,” he explains. The pendants feature a custom adjustable mounting bracket which allows the pendants to suspend parallel to one another, with a dimmable carbon filament-style LED lamp creating the perfect atmosphere to relax and take in the view of the surrounding nature. Fox believes that the lighting was critical to the success of the project. “By being able to adapt to any external or internal influence – as well as assisting with multifunctional events such as conferences, entertainment functions, exhibitions and art workshops, the role the lighting plays in the finished project cannot be overstated.” The Gallery was officially opened in November 2021, with the inaugural exhibition of The Stars are Bright, a collection of important art from the Cyrene Mission School, Bulawayo (competed between 1940-1947), by more than 40 resident artists, under the tutelage of Canon Ned Paterson.

Lighting defines and celebrates space at CT café

Lazari in Vredehoek, Cape Town, is a popular coffee shop which reopened this April with a brand new look.

H anno de Swardt from Onnah Design was tasked with the renovation, and he notes that the owner’s interior design brief was clear from the get-go and in line with his vision for the space. “They wanted a warm and inviting space, lighter and brighter than before. A space that was relaxed and comfortable, encouraging customers to linger longer. The circulation and flow had to remain easy and practical whilst retaining a maximum seating plan. The introduction of a new banquette seat and a bar counter along one length of a shopfront were the obvious design interventions here,” he says. The need to charge mobile phones or work on a tablet or laptop were met by introducing plug points in various easy-to reach areas.

The client also added some new and exciting Mediterranean dishes to the menu which had to tie in with the new look. This was successfully accomplished through the use of all the different finishes, colours and design elements. “A final requirement was to resume trading as soon as possible, so the project team had a rather challenging deadline to meet. However, with proper planning and project management we met this part of the brief and the shop was soon trading at full capacity. De Swardt created a lighting brief for the client based on a site survey and assessment. “The only lights retained were a few decorative pendants that complemented the new scheme. As for the rest, we introduced new lights throughout. The idea

specific design features. “Blessed with ample floor to ceiling height I could celebrate the volume with woven wire pendants and terracotta pots with dried Eucalyptus Populus, hung upside down, just for fun.

was to improve the general lighting levels in the space and create a fine balance between efficient task lighting and effective decorative lighting,” he explains. The proposed furniture layout and new lighting layout had to make practical and aesthetic sense and complement each other as opposed to compete with each other. Task lighting was introduced where required and the more decorative lights were used to celebrate the volume and

us to hang 75 coffee cups, lit by small star lights, introducing a super fun element and focal point to the shop. Furthermore, the use of concealed LED strip lighting was introduced to highlight certain important elements in the space. A cosy lounge corner in the space now boasts a bright neon sign on a blue wall creating a fresh new ‘Instagramable’ look,” says de Swardt. Furthermore, star lights were used within a cantilevered bulkhead to highlight 75 suspended coffee cups. Thin black pendants along the shopfronts were added, fulfilling roles as both decorative and task lights. The back-of-house kitchen received a new fluorescent light whilst the old, unsightly, ceiling mounted fittings outside were all updated with new contemporary fittings. Even though the space is relatively small there were fortunately enough opportunities to create a visually appealing and exciting space, which

Chair Crazy, in line with the desired look and feel. Three walls were identified as feature walls and were treated as such through the use of colour and neon signage, applying wallpaper and lastly wall decoration in the form of colourful plates, tinted mirror cladding and shelving. De Swardt says emphat i ca l l y, “Never underestimate the importance of good lighting for both architectural and interior projects.” In this project, in conjunction with all the other design elements, the lighting plays a crucial part in defining and celebrating the space. “Without the lighting, the scheme would ‘ fall flat’ and become insignificant. This is a prime example of where a sensitive approach to lighting and the considered implementation thereof contributes immeasurably to the pleasant experience of a space and the successful visual definition of an interior.”

was de Swardt’s main goal. “As Lazari is such an iconic venue in Cape Town, we thought it wise to keep some of the old items in the space and just spruce it up. I took the approach of ‘something old, something new, something borrowed, something blue’. In line with the client’s brief, I drew further inspiration from the Mediterranean, introducing warm blues as the main accent colour, offset against calm, relaxing, earthy tones,” he says. The new Cemcrete floors were the main point of departure, replacing the previous black slate tiles. Oak lookalike melamine was used for the new table tops and to define the new custom made banquette seat, by Bespokeliving. The front-of-house kitchen counters were enhanced with cladding in the form of thin vertical oak strips on a black backdrop, giving it a completely fresh contemporary look. An interesting mix of dining chairs were procured from Patio Warehouse and

Connected thinking: Wi-Fi through urban lighting

We live in the age of the internet. Constant connection is the new normal: we work, shop and sometimes even fall in love online. Smart technology can empower and connect communities, improving offline life.

S mart technology encompasses a wide range of concepts, fromkeeping residents informed about services via their smartphones, to providing charging points for electric vehicles. That’s just the start of how WiFi and other technologies connect cities: they also drive innovation, connect businesses and customers, and help make cities #selfieready. But did you know that street lighting can now play a vital role in providing connectivity? Schréder created the Shuffle to be much more than an energy-efficient lighting system. It provides a reliable and secure infrastructure for WiFi, meaning sufficient bandwidth is available for a perfect surfing experience 24 hours a day, 7 days a week. It can also be used to deploy small cell 4G or 5G in partnership with telecoms operators. Or both! Up to five modules can be placed in each Shuffle pole, so the only limit is your city’s ambitions. Whatever options you choose will foster a more vibrant community by connecting citizens, businesses and visitors. Boosting local economies: How a roman city gives 5 000 tourists free WiFi A case in point is Trier, Germany’s oldest city. The

diverse needs of the population make a clear use case for free WiFi: there are 20 000 students, two million tourists every year and, as across much of Europe, a small part of the population who do not have access to the internet at home. Free WiFi helps this last group bridge the digital divide. It’s accessible to everyone: Trier provides free WiFi on all bus routes, which has also made public transport more attractive – you can’t do online shopping, chat to friends or finish an essay while driving! In the area around Hauptmarkt, the main market square, all residents and visitors can connect, for free, for an hour each day. On average more than 5 000 people take advantage of this service daily, with notable spikes when tourists arrive. Residents can have up to four hours free if they download the city app. No tracking is carried out on the app in compliance with GDPR regulations, avoiding a headache for authorities. For the tourists, a free internet connection avoids hefty internet roaming charges, leaving them free to share #content about their visit, stay longer, and in turn, boost the local economy. And there’s another advantage for cities who want to preserve their heritage: as the WiFi access points are integrated in Shuffle columns located

16

LiD Q2 - 2022

all the integrated technology. “We are waiting to see the ramp-up in E-charging in South Africa, and the Shuffle will be a perfect product for that. Universities, particularly, have shown a lot of interest in the Shuffle withWi-Fi, charging stations, SOS (to name a few) and we are also able to specify this to the needs of the customer.” Combrink says that while abroad the Shuffle has been used predominantly in urban areas, parks, plazas and to showcase historical areas, he believes that locally – and this has been backedup by feedback from the market – the focus will be placed on the Shuffle’s functional features and security aspects. Nobody knows exactly what the future will look like, so adaptability is built into the company’s smart city products. Shuffle modules can be added, replaced or exchanged as requirements evolve. But the pole itself isn’t going anywhere: Shuffle is a sustainable solution.

throughout the city centre, there was no need to dig up the ground around the UNESCO World Heritage sites. European examples Also in Germany, the Bundesgartenschau is a garden festival which lasts 173 days and enables cities to create sensational outdoor spaces and events. Heilbronn was the 2019 host city, drawing 2.3 million visitors to projects including the transformation of the Neckarbogen area into a “district of the future,” complete with almost 300 Shuffle columns. All are fitted with LED lighting and an Owlet IoT control system to adapt lighting for events taking place. Some have WiFi hotspots and others have charging points for electric cars. As the smart city becomes a new reality, residents of the area are early adopters for the fully-connected neighbourhood. Shuffle’s endless adaptability is a springboard for innovation. One particularly creative way to use them is to create site-specific installations. It could be information about sports teams in Shuffles around their stadium, facts about marine life on a seafront walk, or taking visitors on an interactive journey with a touch of immersive smartphone magic. Another hit with young visitors is Pairi Daiza, a 65-hectare wildlife park in Belgium. Open all year, it needs to be lit in a way that respects the animals’ needs. When the client explained their specifications, Schréder designed bespoke elements for the Shuffle to ensure the columns blended in seamlessly with the landscape and didn’t disrupt the animal inhabitants who live there. The light poles are also available with a specific coating that makes it adapted to demanding environments such as seafronts and piers, such as Uberlingen’s Seepromande, an elegant boardwalk along the German shores of Lake Constance. Around 50 Shuffle poles light the lakefront, with Wi-Fi installed in several to ensure even coverage. While switching to LED lighting will provide energy savings for the town, their main driver is creating a welcoming evening ambiance and adding connectivity. A local perspective Froma South African perspective, BEKA Schréder’s Grant Combrink notes that the Shuffle is one of the company’s premium products. However, there have been numerous installations and proposals to fuel companies, schools and universities, mostly due to the versatile nature of this product with

Connected lighting in the retail market Grocery and large retail have been forced to adapt to the evolving landscape, accelerated by the coronavirus pandemic. Customer expectations have shifted with the influx of online shopping and brick-and-mortar retailers have been required to provide an omnichannel experience while

improving a store’s operational efficiency. T he retail landscape has evolved in recent years with the growth of online shopping. The pandemic led to reduced opening hours, restrictions on the number of people allowed in brick-and-mortar stores, and concern over safety of indoor exposure to the virus. Although grocery stores have seen fewer disruptions than other re tail, due to their essential nature, many have been required to modify their opening hours, leading consumers to experience grocery delivery or pick up rather than shopping in-store. In addition, shop pers have decreased their number of store visits overall, opting instead for weekly store purchases. The pandemic has also led to an increased amount of spending in a decreased amount of time. Accord ing to a study in Europe and the US, spending per minute increased by 49%. Similarly, another study found that European customers reduced shopping by an average of 5%while simultaneously increas ing basket size by roughly 16%. These shifts have created many challenges for the retail segment, especially brick-and mortar retailers that have had to adapt quickly to handle the increase of purchases with an influx of online shopping combined with the need for pickup and delivery options. The importance of an omnichannel retail approach has become more apparent than ever before. Although this evolution in shopping trends has created challenges for the retail segment, it has also revealed opportunities. Through technology advancements, retailers

can address many pain points, provide a more experiential and personalised experience with omnichannel shopping, reach sustainability goals, and achieve operational excellence through energy savings, staff efficiency, and improved store maintenance. Retailers have massively adopted LED lighting and environmentally friendly refrigerators and are increasingly adopting self-checkout solutions and electronic shelf labels. Lighting controls have evolved, enabling new levels of energy savings, ambiance creation, and operational efficiency through advanced scene setting, sensor automation, and remote monitoring and lighting management. Adoption of indoor positioning systems (IPSs), utilising lighting solutions, has grown in recent years across many verticals, with retail seeing especially strong growth due to the benefits and use cases available within this sector. Although location-based services and mapping via GPS are commonplace in the outdoor environment, this functionality has not always been available indoors. IPSs can provide value to facility owners, managers, and corporations, as well as shoppers and employees within in a retail store. Retail trends Shifting customer expectations: With the increase of onl ine shopping, to draw in customers, grocery retailers need to differentiate their store experience, shifting their store format from

18

LiD Q2 - 2022

savings as well as occupant controllability. The third stage, networked lighting, came with the adoption of dimmable LED luminaires and lighting control systems that provided automated schedules and granular scene setting capabilities that helped retailers to reduce energy consumption and enhance store ambiance. In this stage, there is one-way communication to the luminaires. Grocery retailers frequently connect their lighting control system to their building management system (BMS). BMSs have primarily been used to monitor and manage store refrigeration and HVAC and alarm systems, and the centrally defined schedules trigger scenes in the lighting controls though a simple localised integration. For the fourth stage in the evolution of lighting controls, connected lighting, Guidehouse Insights uses the U.S. Department of Energy definition, which is an “LED-based lighting system with integrated sensors and control lers that are networked, which can be either wired or wireless, enabling lighting products within the system to communication with each other and transmit data.” This stage includes bi-directional communication within the system, and the lighting system has the ability to collect and process data for enhanced insight. The fourth stage is facilitated by the advent of intelligent LED luminaires that are able to generate data on energy consumption and failures, lighting controls that are able to gather these insights and securely transmit them to a cloud based solution that can store and process the data with advanced analytics to deliver deep insights and benchmarking on energy consumption, lighting failures, and compliance with centrally defined lighting scenes. These insights can be used at a corporate level to define further energy reduction optimalisation, as input for sustainability reporting, and fed back to the store for the store manager to gain insight in-store performance. Such intelligent LED luminaires may also be out fit ted with advanced sensors that, for example, enable people counting, and register temperature, humidity and noise levels. Such features could be useful for applications beyond illumination. With the advent of LED lighting, lighting companies have found that the capabilities of

transactional to experiential. The influx of online shopping has provided consumers with a more personalised shopping experience, with store apps providing suggestions based on past purchases and highlighting sales or popular options. This experience has increased the ef ficiency of shopping and led to shifting customer expectations when shopping in a brick-and-mortar store. Operational challenges: Retai lers face a multitude of operational challenges from rising electricity bills, increased customer expectation for store experience, and staffing turnover to reduced budgets and a lack of in-store analytics. Labour shortages, increased wages, and the high estimated cost of replacing hourly workers increase the need for operational efficiency. By increasing automation through Internet of Things (IoT) technologies, retailers are able to reduce some manual labour. Sustainability goals: Retail companies need to reduce operating costs, both to improve budgets as well as address customer sentiments over corporate environmental concerns. Increasingly, customers are choosing to support businesses that are addressing climate change, which has pushed many companies to set corporate sustainability goals and show customers how they plan to address climate concerns through environmental, social, and governance initiatives. Connected lighting solutions for retail Tradi t ional l ight ing systems operate on a programmed scheduled or manually controlled switches and breakers. The brightness and colour temperature of these systems are not adjustable to daylight levels or occupant demands. Sensor lighting is a non-networked lighting system that includes sensors, such as motion or occupancy sensors. Although these systems use sensors, they are not networked, and the luminaires do not have the ability to communicate. Sensors for these lighting control systems enhance energy

are a click away.

Connected lighting enabled market trends Connected lighting solutions allow retailers to cut energy use through the use of LEDs and controls as well as integrate into BMSs. Connected lighting solutions are uniquely positioned to address these key areas, and control strategies that are implemented with connected lighting systems result in additional energy savings. These strategies include occupancy sensors to adjust lighting when they sense a presence (or lack) of people and daylighting to allow lighting to be adjusted based on the amount of natural light. Luminaire-level lighting controls use 25%- 75% less energy than non-controlled fixtures. Energy savings make an ROI for a retrofit of LEDs and lighting controls within the capital budget for companies. IPS can provide customers an experience more akin to an online experience, which can alleviate some frustrations around finding items easily. Many retailers offer their own mobile app, which allows a customer to create a shopping list and, upon arriving at the retailer’s brick-and-mortar store, the customer can then gain access to real-time inventory information and assistance in finding specific products. Additionally, through the app, retailers are able to offer personalised promotions based on past purchases and send location-based reminders of these promotions when a shopper is in-store. Likewise, a grocery retailer could offer coupons based on overall purchase spend, or another metric, to help increase customers’ overall spend, either in-store or online. Beyond providing reduced energy use, an omnichannel experience, and overall enhanced experience to customers, an IPS that is made possible through connected lighting solutions can enable handheld store navigation, which allows employees to instantly locate any item a customer needs assistance with as well as save time for employees fulfilling online orders. Store data that employees can easily access can allow them to search for a product and identify not only where it is located within the store but also if the item is in stock, without having department specific knowledge. The increase of online shopping has created a major benefit to retailers: the ability to gather significantly more data and insights into customer buying behaviour. Historically, for in-store customers, retailers’ loyalty programs provide the cornerstone for shopper purchasing behaviour. By combining this program with an IPS, retailers can gain increased analytics beyond sales figures to customer behaviour in stores. Gaining improved insights into customers, products, and employees can provide a retailer with a competitive advantage over their peers. Analytics gained from an IPS can include the average time a customer spends in a specific

LED also enable the pursuit of opportunities beyond illumination. For retail, the most notable is the use of LED lighting as an IPS. The two most prominent communication protocols that enable IPS are Visible Lighting Communication (VLC) and Bluetooth Low Energy (BLE). Bluetooth is an open wireless technology developed by Ericsson in 1994 specifically for sending and receiving data over shor t distances. Often, lighting vendors install luminaires with embedded Bluetooth beacons, which allows for the ability to use these capabilities later without the need for additional hardware. VLC is the combination of illumination and communications. It is an advanced communications technology using visible light roughly between 375 nm and 780 nm. Data is communicated wirelessly through minor non-visible variations in the light and received by a device with a front-facing camera. VLC technology is typically integrated in digital drivers (i.e., drivers that support the digital addressable lighting interface lighting control protocol), making it easy for a luminaire manufacturer to implement. The most notable use of VLC is for indoor positioning in the retail segment, as VLC offers the higher positioning accuracy that is required in retail, and LED luminaires are not subject to the mounting height restrictions of BLE beacons. VLC can also work in conjunction with BLE, whereby BLE could be used for in-pocket notifications and VLC for indoor navigation. Indoor positioning using VLC or BLE is obtained by a building owner or manager using LED lighting that is VLC enabled or that incorporates a BLE beacon. A retail customer downloads an app that allows the VLC software to connect to the user’s smartphone camera to access their location. In the case that only BLE is used, permission to connect to the user’s Bluetooth function to access their location is required. The ability to pinpoint the exact location of a customer and provide them with targeted coupons, product information, reviews, or in-store help by a sales associate offers an improved shopping experience. This experience is comparable to online shopping, where additional product information and discounts

since the beginning of the pandemic. Retailers were forced to adapt quickly and many now offer some type of omnichannel experience with options for online ordering and delivering or online ordering and pickup at a physical store location. However, providing an omnichannel experience is not be enough to maintain a competitive advantage, and retailers need to work on enhancing this experience. • Retailers must gain improved insights into customers, products, and employees. Online retailers are easily granted access to customers’ shopping trends and popular products; gaining these insights for brick-and-mortar retailers is more cumbersome. However, connected lighting solutions can enable these insights for retailers to improve customer loyalty and provide experience more akin to an online shopping experience. • Retailers need to understand their options for connected lighting. Through LED upgrades, some retailers have purchased connected lighting systems with the availability to begin using the software capabilities later by upgrading for those capabilities, such as through connecting the stores to Interact Multisite management from which the entire chain can be managed and monitored. Or by adding in Interact indoor navigation. In this way, retailers have worked to future-proof their brick-and-mortar stores, but as store and facility management turns over, the availability of this functionality might not be clearly understood by new stakeholders. The benefits of connected lighting extend beyond a single store location. For retailers to fully realise the benefits of these solutions, they should prioritise expanding to multiple sites. Doing so not only provides the retailer with reduced energy savings, improved operational efficiencies, and expanded insight into their portfolio of stores, but also an enhanced omnichannel experience for their customers. Guidehouse Insights prepared this white paper, commissioned by Signify, to provide insight into connected lighting solutions and IPSs within the grocery and large retail market.

department, a more accurate view of the average time spent in-store, the number of departments visited, and the average time spent in front of an advertised product, among others. Signify’s Interact offering is one example of a connected lighting system that provides a flexible solution that delivers lighting IoT capabilities in a number of professional application areas, include grocery and large retail. Signify’s offerings include the connected lighting system, such as the luminaires, sensors, and controls, as well as software. Signify’s Interact software application integrates data from a connected lighting system with other smart retail solutions. The company’s Interact offering focuses on scene management, energy optimisation, l ighting management, and indoor navigation. These four core areas address the key retail trends discussed earlier. Signify’s indoor navigation and location analytics support personalised shopping and provide staff efficiencies, such as improved workflows and improved store layout and operations. Additionally, Signify’s offerings provide multisite management, which al lows for ef fectively managing and monitoring the connected lighting in large groups of stores, whether these are super- or hypermarkets or express stores or a combination of the three. Conclusions and recommendations To gain and sustain a competitive advantage, retail market stakeholders should consider the following recommendations: • Retai lers need to strive for operational excellence. To effectively compete in the evolving market, retailers need to work smarter in the face of increasing energy bills and labour shortages. By implementing connected lighting solutions, retailers are able to monitor and manage their store lighting remotely, saving maintenance visits and driving down energy consumption. • Retailers should prioritise sustainability goals. For many retailers, reducing their carbon footprint is already top of mind. Prioritising this goal not only helps retailers reduce their energy spending but also allows them to address customer sentiment over corporate environmental concern. Investing in a connected lighting solution provides one option to prioritise this focus through energy savings from LED lighting and lighting controls while providing the other non-energy benefits discussed here. • Retailers must enhance their omnichannel shopping exper ience. Even before the coronav i rus pandemic, the growth of digitalisation was pushing the retail market toward providing an omnichannel shopping experience. Although this trend was not as common among grocery retailers, it had already started and has grown exponentially

Tailor-made lighting for a circular economy Signify now offers its customers the opportunity to design and adapt their own custom lighting, which is then printed in 3D. This simultaneously saves on time, energy and waste during manufacturing, as well as packaging and transport.

T here has been much discussion over the years regarding lighting and controls’ impact on the environment. With little debate, the LED rev olution has significantly improved energy efficiency of light sources. Additionally, this has allowed for both more efficacious luminaires and creativity in fixture design due to the small footprint of the LED light source. As light sources have shrunk over the years, luminaire manufacturers have had to consider brightness, luminous intensity, and glare, amongst other important characteristics, when designing new fixtures. Other than greater efficacy in the light source, smaller apertures, and power supplies, what else has changed within the fixture? The answer is very little until recently. 3D printed luminaires are beginning to offer more versatile and flexible options for non-recessed products. 3D printing for lighting paves the way for more innovative designs, with different shapes and more complex colours. Signify has developed a manufacturing method that is both flexible and sustainable through the use of a fully recyclable polycarbonate. This enables you to quickly design or modify your lights according to your needs. At the end of their life, your equipment/materials are recycled and reused/remelted to produce new lighting. This intelligent modular design of the luminaires allows Signify to extend their lifespan and reduce the company’s carbon footprint by up to 75% compared to traditional luminaire production. From design to production, the waste of resources is minimal because the company recycles almost all of the fixtures, produces only the quantity strictly necessary and do not use screws or paint.

3D printing: How does it work? Signify is firmly committed to lowering its carbon footprint. Its 3D printed and 100% recyclable lights reduce your environmental impact as the company uses 100% recyclable polycarbonate, allowing new fixtures to be printed from old materials. 3D printing involves depositing a recyclable polycarbonate thread in a predetermined shape and thus shaping a form. Signify print the luminaire body with the parameters chosen by the customer and associate it with an LED module whose technical characteristics have been selected (flux, dimming, colour temperature, etc.) The creation and customisation of lighting is done on an intuitive online configurator where customers choose the type of lighting (ceiling, recessed, projector), its colour, its opacity and its texture, so that they can shape a unique identity for an unparalleled customer experience. Whether you are looking for luminaires of a certain colour, or of a certain size or cut-out, Signify has the solution. The company offers endless combinations of shapes and lighting options, and, furthermore, customers can even return their 3D printed luminaires to have them recycled and reprinted in newer designs.
