Message from the GMSegment innovation brings resultson a global scaleIn reviewing this issue of Lightnews, our businessand the value we deliver to you as customers, I wasamazed again at some of the major differences betweenthe possibilities that a lighting controls lead approach(including integration possibilities) presents, versus abuilding management system only approach. The need fora deep understanding about users, operators and ownersand the architectural space they occupy, requires greatcare and balance in the approach to any solution ratherthan just the efficient control of a buildings services.That fine balance of maximising comfort and minimisingenergy usage – the context of which needs to beaddressed differently depending upon the type of buildingspace we control – is much more than just consideringa set of plans in two dimensions. Or calculating areas tobe controlled and providing a bill of materials or a list ofcomponents as a solution.This issue of Lightnews showcases the capabilities andsuccesses in our lighting controls lead approach by ourown resources and those of our chosen partners andcustomers on a global basis.In South Africa we review two office segment projectsincluding a ground breaking building “lightwall” innovationfor a telco facility and 50000m 2 of floor space undercontrol for a major financial institution. In the UK ahistoric property is converted to a major multi-functionalhospitality facility and is building their brand, maximisingenergy savings and getting operational efficiencies througha facility-wide approach. Also in the UK, a new luxuryresidence in the very heart of London, gets a sophisticatedhome automation control system that provides it’senthusiastic owner with unrivalled performance,controllability and energy-efficiency.As part of their Middle East brand expansion plans, Marksand Spencer are enhancing revenues and giving shoppersa better in-store experience. Heading further East wesee the results of an even clearer understanding ourcustomers unique needs in upgrading and retrofittingexisting facilities, whilst they remain fully operational. Thewhole race track lighting control system was completelychanged at the Singapore Turf Club with no interruptionto one of the world’s busiest race track programs. Andin Sydney, extensions and refurbishments to the SydneyStar Casino complex were achieved by replacing existingsystems, installing new ones and giving the operatorsone central control point to maximise their returns andtheir guest’s experience. Whilst in the US we review ourdevelopments for one of the world’s largest energy usersin providing proof points of our controls solutions.The Philips Dynalite offer is continuing to grow in allregional markets around the globe. This growth is beingachieved in large due to a decision to take a marketsegment, rather than a purely product technology basedapproach. This ensures that in each region and country wehave the right people, with the right ideas, the right contactsand the right approach to the considerations required to getthe best lighting controls result we can for our customers.Now with a clear focus on the requirements for Office& Industry, Hospitality, Retail, Entertainment, Healthcare,High-end residential and custom install users – our platformdevelopment decisions can be maximised for differingsegment customer needs, whilst ongoing investments in theportfolio can be prioritised and leveraged to the benefit andcontinued growth of our business.This focus means we’re all about getting a better resultfor our customers because we understand the needs ofkey stakeholders in these different segments on a granularlevel – what’s important to a Facilities Manager in an Officelooking to maximise energy-savings can be completelydifferent to those of the Facility Manager of a largeEntertainment Centre that has mixed use requirementsincluding events such as Exhibitions, Conferences andBallroom functions, as well as the odd Concert thrown in.Being the Global Centre of Competence for IndoorNetworked Controls, we have continued our heavyinvestment in Research and Development and we areable to see the results in some of our new innovationsand technologies featured in the Product Spotlight and

Light in actionOne horse race when itcomes to lighting controlKranji as the only racecourse in Singapore means the stakes for the operators are high toprovide the latest results and odds to visitors and broadcast viewers alike. When the SingaporeTurf Club released the tender to upgrade the racecourse facility, Philips Dynalite had to crackthe whip to meet the challenges of a field of competitors.Monitoring the energyconsumption of each lightingtower was a fundamental elementof the tender as the STC strivesto improve the facility’s overallenergy efficiency.“”Horse racing in Singapore has along history, dating back to colonial timeswith the first race taking place in 1843.The Singapore Turf Club (STC), managedby the Malaysian Racing Association hasbeen in its current location at Kranji since1999. The original facilities and track designwere hailed as state-of-the-art at the timeand received a recognition award fromthe Philadelphia Chapter of the AmericanInstitute of Architects, for its ‘fun andwhimsical’ design.The racecourse complex comprises sixtracks. The principal track is used forlong- and short-course races over 2,000mor 1,800m. A 1,500m polytrack permits allweatherracing and four tracks are availablefor training purposes. The visitors’ areas andcorporate facilities are equally impressive.When commissioned in 2000, the coursewas floodlit with more than 40 lightingtowers, fitted with 1,800 Watt ArenaVisionluminaires from Philips.In 2007, the Singapore government releaseda tender to upgrade the infrastructurefor the racecourse. A key criteria was themonitoring and control of the lightingtowers, to ensure that the lighting towerswere secure and available for training andrace meetings at all times. With just a shorttime frame in which to respond, ControlTech Asia, the long standing Philips DynaliteVAR for Singapore, was able to designa lighting control system based on coreproducts and technical expertise.To maximise security, STC required tripleredundancy to ensure that the lights wouldremain on when needed. In addition, theflood-lighting system needed to have bothtimed and manual control capabilities foronsite and remote operation. Monitoringthe energy consumption of each lightingtower was a fundamental element of thetender as the STC strives to improve thefacility’s overall energy efficiency.“The overall system has three networksto provide the level of redundancy thatSTC required,” said Ray Bond, BusinessDevelopment Manager, SouthEast Asia forPhilips Dynalite. “Normally, we would runthe controllers over a single bus network,but in this case there were two existingnetworks wired underground. The thirdlayer needed to sit above the original twoon a wireless network, giving three streamsof data to guarantee the system wouldremain on when needed.”“We used an intelligent building as ananalogy when designing the system. Usuallythere would be one control room, butin this case, there are three, giving 200%redundancy! Making sure only one was inoperation and not overridden by one of12 | Lightnews Vol 13

The Singapore Turf Club – Singapore.Photo from EwingColeThe Singapore Turf Club – Singapore.Photo from EwingColethe redundant networks also needed to beconsidered,” Bond said.A key challenge for the installation teamwas overcoming access restrictions. Duringinstallation, the racecourse was fullyoperational. There was no opportunity to‘shut’ the facilities to allow the installers thefreedom to connect, test and commission.The lighting control system was installedin the background until it was ready to beswitched over. It had to be 100 per centoperational, first time.The Philips Dynalite tender submission bytheir experienced VAR – Control Tech Asia,utilised off-the-shelf products, but it was theability to integrate with an existing legacypower system and provide a maintenanceagreement post-commissioning that gave thecompany the green light.The product range used to control thelighting towers included the DDRC1220-GLand DDRC420 Din Rail relay controllersover the Firetide 5.8Ghz wireless networkequipment. Three desktop work stations aswell as three maintenance laptops, runningthe Philips Dynalite EnvisionManager andMapView software were supplied to overseeand manage the system.Monitoring of energy consumption andcomponent failure and integration with thirdpartypower meters required the PhilipsDynalite team to write special software.Each tower’s monitoring system is housedin outdoor enclosures, linked by cables andwireless networks. By linking the towers, themaintenance crew can readily establish whichtower is exhibiting abnormalities, based onirregular power consumption behaviour andrespond accordingly.The use of outdoor enclosures to housethe equipment in the high heat and humidityof Singapore presented a whole new setof challenges. “Some of our equipment hasbeen modified to tolerate the conditionsto literally protect them from meltingin the heat,” said Bond. “Being a tropicalenvironment, a huge amount of protectionhas also been added to cope with the highrisk of lightning strike.”The second phase of the Kranji racecourseredevelopment will focus on control ofthe broadcast monitors around the track.As racegoers move around the complex,individual races and betting information areconstantly broadcast and updated on thedisplays. With the monitors fully integrated,energy consumption of each screen canbe monitored based on the amount ofcurrent drawn. “Power consumptionmonitoring is rapidly becoming a corerequirement for many businesses in theregion. With monitoring equipment andenergy-efficient LEDs and luminaires, wecan provide companies with opportunitiesfor improvement in their energy savings,”concluded Bond.The project at Singapore Turf Clubracecourse highlights the increasing demandby many companies for quality productsand service. The ability to adapt to specificclient requirements allowed Control TechAsia to meet the unique and complex needsof the Singapore Turf Club. The flexibility ofPhilips Dynalite lighting control equipment,and its capacity to integrate to and optimise,existing systems, will ensure that the Kranjiracecourse continues to be the number onehorse racing venue in the region. nLightnews Vol 13 | 13

Industry insightIntegrating for astreamlined BMSLighting features in every room on every floor of every building. Therefore, it makessense to integrate any additional services, such as airconditioning or automatic blinds,into the lighting control system as part of the building management infrastructure.With this in mind, the Philips Dynalite lighting control system is second to none inproviding integration with a range of third-party devices.Systems integrationtakes a holistic approachto commercial buildingmanagement.14 | Lightnews Vol 13The concept of buildingmanagement systems (BMS) isnot new. However, the use of systemsintegration to streamline buildingmanagement is rapidly evolving as more andmore demands for high level functionalityand aesthetics for occupants (comfort) andenergy-efficiency for the building, becomedriving forces for commercial applications.The key attraction for installing a BMS isas the name suggests, to manage the manycomponents that the whole building, as wellas individual office suites may require. Therange of applications that can potentiallybe managed is extensive, from HVAC tosecurity and maintenance to lighting controlthat includes daylight penetration into thebuilding. System integration in a commercialsense is therefore the ability to integratethird-party products, regardless of provider.As buildings become more intelligentand energy-efficient and the demandsfor occupant comfort rise, the need forintegration in an overall system increases.Just another day at the officeThe level of integration available can bedemonstrated by an everyday occurrenceat a commercial building. As a car entersthe under-building car park, the lights areautomatically adjusted to suit the time ofday to allow the drivers’ eyes to adapt. Toopen the boom gate requires a swipe card.The staff identification system is maintainedby the BMS database. Upon recognition ofthe driver and swipe card, the gate is liftedand illumination is increased along thepathway to the driver’s designated car space.The lights from that car space to the nearestelevator or exit are also illuminated to givethe driver a safe pathway into the building.The building management system also knowswhich floor the driver works on and activatesthe lights for the elevator foyer on that floor,corridor lights to the appropriate officesuite, office reception area and bathroom.The airconditioning setting adjusts to its‘occupied’ state, the blinds open to maximisethe available sunlight and the lights areactivated above the employee’s workstation.As the employee enters the conferenceroom to prepare for a meeting, presencesensors activate the lights in that zone. Viaa user interface the employee activates theprojector and screen, alters the pre-setlight and blind settings to reduce glareand increases the temperature a little toaccommodate the overseas guests.Putting the building puzzletogetherThe preceding scenario is fairly typical ofany commercial application, whether it befor an office, hotel or hospital. By integratingall the elements required to make anenergy-efficient, safe and comfortable workenvironment, the building managementsystem is able to monitor and report onthe building’s status. Energy consumptioncan be economised by turning servicesdown (or off) when rooms are unoccupied;security can be maintained and audited;safety requirements can be adhered to andmaintenance such as re-lamping can bescheduled for non-occupancy periods.Standard industry protocols such as KNX,Lon, BACnet, RS232, RS485 and TCP/IP arefacilitating the ability to streamline systemsintegration. By providing gateways betweenthe Philips Dynalite DyNet backbone andthird-party protocols, building managers andowners have the ability to seamlessly linkcomponents into a single control system.With a fully integrated building managementsystem, the building supervisor is in aposition to optimise energy consumption,building maintenance and administer accessrights, whilst providing the occupant withuser interfaces to tailor their individualwork area to take advantage of natural light,audio-visual needs and temperature.Providing systems integration for buildingmanagement need not be confinedto new buildings. As many existingbuildings have false ceilings and risers fortelecommunications and power, accessto these ducts to install the backboneinfrastructure is relatively easy for retrofittingan office or an entire building.Similarly, changing the layout of an officesuite is not an insurmountable problem –if an extra luminaire needs to be added or

moved, the DALI controller can be editedto reflect this change. Re-arranging an officespace in this fashion avoids wasteful andintrusive re-cabling and extends the lifetimeof the overall infrastructure.The Philips Dynalite system has beenspecifically designed to take advantage of theDALI standards for communication betweenpassive and active interfaces. Typical examplesof passive interfaces would be occupancysensors that activate light levels whereasactive interfaces are devices such as keypads,touchscreens or remote controls. With a fullyintegrated system, inputs to user interfacescan be relayed back to the BMS. Continuedchanges to preset settings can be trackedthrough the BMS reporting facility such thatalterations can be made to accommodate thechange in preference settings.Systems integration for commercialapplications provides a holistic approach– with an intelligent building managementsystem at its heart to control, monitorand report. Philips Dynalite continues toincorporate more third-party products –such as their alliance with Somfy the worldleader in motors and automatic controlsfor openings and closures of homes andcommercial buildings – into the oneframework and collaborate with otherindustry leaders to further facilitate highlevelfunctionality, improved sustainabilityreduced energy consumption and increaseuser comfort. nBalancing Light withPhilips and SomfyThe partnership of Philips Lighting and Somfy continues toprovide a unique balance between natural and artificial light.By utilising occupancy sensor technology, the Philips ControlsOccuSwitch DALI (sensor/load controller combined) andSomfy blind motor controllers, now work together to maximisecomfort for building users and minimise energy usage forbuildings owners and operators.The OccuSwitch DALI is designedto respond to occupancy and lightlevels to minimise energy consumption.The simple act of turning off lights cangenerate an energy savings of up to 55%for any vacant area. Adjusting the blinds viathe Somfy motor controllers to optimisedaylight harvesting will further reducecosts associated with heating and coolingand get a better overall energy reductionresult whilst enhancing office and classroomenvironments.In an office or classroom, enhanced lightingmakes for a safe and productive workenvironment. The light from windows maynot extend throughout the entire room.This leads to variations in light levels. TheOccuSwitch DALI will address the variabilityby dimming the lights nearer the windowor increase the corridor lamps to createthe light scheme required for the room. TheOccuSwitch DALI sensors will interfacewith the Somfy motor controller to alterthe position of blinds to balance natural andartificial light levels.The stand-alone configuration of theOccuSwitch DALI product is an easy toinstall solution, connecting directly to themains power of the room or area andcan control up to 22 DALI compatibleluminaires. Moreover, the unit can beconnected to a building managementsystem to give basic integrated networkfunctionality. In either scenario, theOccuSwitch DALI is designed to overrideany pre-set levels and communicate withthe Somfy motor controllers, based on theoccupancy status of the room.The retractable sensor shield featureof the OccuSwitch family is designed toprevent the unit from responding to lightlevels unnecessarily. For example, wherea corridor wall is semi-transparent, aretractable sensor shield on the OccuSwitchThe Philips ControlsOccuSwitch DALI workingtogether with Somfy foroptimal energy savings aswell as lighting control andenvironmental easily rotated by hand to prevent theunit from detecting the light through thepartition. The OccuSwitch provides thecorrect level of light that is appropriate forthe room, without the influence of the ‘falsetrigger’ originating from the corridor.The OccuSwitch product range, in particularthe OccuSwitch DALI, provides a versatile,easy to install solution for office andclassroom applications. Interaction withSomfy blind motor controllers provides theoccupant with a level of illumination that isdesigned to suit the changing natural lightlevels throughout the day. The overall resultis an environment that maximises energysavings and enhances the comfort and safetyof the occupant. nLightnews Vol 13 | 15

Light in actionThe Star, Sydney – Lights ofthe façade and external publicareas are being controlled bythe Philips Dynalite solution.Odds stacked in favour ofLighting Control SolutionInstalling and commissioning a lighting control system for a single hotel renovation is recognised asa major undertaking. But incorporating the construction of a new hotel and the refurbishment of amajor casino complex – all to be completed in stages – is not a gamble to be taken lightly.The Star City hotel and casinocomplex in Darling Harbour, Sydney, isundergoing a major, multi-million dollarrefurbishment including the lighting in thetwo hotels and casino, as well as all façadesand external public areas, with the selectedlighting controls solution being managed byPhilips Dynalite.Owner of the complex, Echo EntertainmentGroup, is in the process of renovating thecasino, building a new six-star hotel andrefurbishing the existing 480-room hotel.The complex will also be rebranded as“The Star”. Sections of the casino are beingprogressively closed as the renovations arecarried out. The upper levels of the originalhotel are no longer accessible to the publicwhile construction work takes place. Thenew hotel, with nearly 200 rooms and suitesopens in October 2011.As the renovations have progressed in eachsection, all electrical switchgear has beenupdated and the existing lighting controlsystems replaced with a Philips Dynalitesolution. The lighting management systemfor the entire complex will be controlledfrom a central, head-end computer runningthe latest EnvisionManager software. Eachnew section of casino refurbishment willform a new segment of the networkedsystem with cables running back to thehead-end computer.Total cost of the whole scheme –refurbishment of the casino, hotel renovationand new construction – is in excess of$950 M. According to Grant Thomson,Channel Manager Indoor Controls at PhilipsDynalite, the aim of the project is to “changethe perception of the whole complex andfor it to be seen as a major rival to otherlarge casinos around the country, providingimproved entertainment and gaming facilities.”Another aspect of the project is the planfor a multifunction 4,000-seat venue,where conferences and similar events cantake place. As part of the drive to alterthe perception of the casino in DarlingHarbour, the type of food available willalso be changed. The takeaway and foodcourt outlets will be replaced by severalnew restaurants, some under the charge ofMichelin-starred chefs.The redevelopment is an on-going projectwith work continuing for at least anotheryear. Another part of the project is thereplacement of the façade and externallighting, all of which is to be linked into theone control system. “The new hotel isbeing built from the ground up,” Thomsonsaid. “The job is massive; practically everylight in the building will be under the onecontrol system.”There is a specific set of Philips Dynaliteequipment for the rooms, a different set16 | Lightnews Vol 13

for the corridors, including DIN-rail or wallmounted lighting controllers in electricalenclosures or rooms. The façades andcorridors use yet another set. Thomsonstated that all the products used are stock,off-the-shelf, units. The only customisationapplied to the equipment involved thephysical button sets and configuration onthe Revolution wallpanels used in the roomsto suit guests needs.A welcome in every roomThere are four types of private roomsthroughout the new hotel: standard roomsas well as junior, executive and signaturesuites. The contract for the electricalfitout was let by a separate tender foreach type of room. As Philips Dynalite wasalready contracted to undertake the casinorefurbishment, the company was in a goodposition to win the tenders for the roomfitouts according to Thomson. In additionto the rooms, the Day Spa lighting, lobbylighting and all corridor illumination, wereseparate contracts.Philips Dynalite submitted tenders forthe 113 standard rooms, 35 junior suites,eight executive suites and the luxurySignature Suites on the top two levels ofthe new hotel. “While the contractor waslooking at the jobs as separate entities,they also had to consider that all of thepieces must work together” Thomson said.Part of the challenge was that the controlsystem needed to be flexible enoughto control a wide range of light fixturesfrom a range of different manufacturers.The lighting management system was ona separate contract to the luminaires. Therefurbishment is making extensive use ofenergy-efficient LEDs, including some PhilipsColour Kinetics dynamic and animatedlighting installations around the complex.The project also included dimming of theLED reading spotlights above the beds ineach room. According to Thomson, this is aproblem for all manufacturers and his teamtested lamps from 15 manufacturers butfound only one in the market that dimmedcorrectly; it was not a case of changing thefixture but the whole light fitting.The management system also hadto communicate with the separatecontrol systems in each room for theinternal services, including door locks,airconditioning and audio-visual control.In addition it will send a Dynalite controlsignal to set, for example, a ‘Welcomescene’ where a particular light level is setand displays a personalised greeting on thetelevision in the room.While there are Philips Dynalite wallpanelsthroughout each hotel room, guests can alsoutilise the TV remote to control the lightsand music from the SuiteControl providedby the Control4 GUI front-end which canalso be displayed on the room TV.Integration challengesThe development of the integration betweenthe third-party systems is always challenging.The SuiteControl system required a special‘driver’ in order to communicate with thePhilips Dynalite system, but the one providedwas only written to a particular level.Thomson stated that the Philips Dynalitedevelopers had to program around thelimitations of the driver. A major limitationwas that it is written for each room andcannot be copied simply from one roomto another. For a ‘typical room’ this can bea relatively quick procedure, but if thereare variations, the programming must bechanged. For example, if a typical room hasfive circuits, but a corner room only four, theintegration has to be modified.“We rose to the challenge and got itresolved, so that now and in the future thehotel operator benefits as a result of ourintegration efforts,” Thomson stated. “Therooms are not directly linked so any changehas to be physically made in each room,which conceivably could be half an hour perroom without our solution.”As a guest enters a room there is a lighton in the corridor and you choose yourlighting scene from a wall panel. A guest orthe housekeeping staff can select either amorning or afternoon ‘scene’ by pressinga button. There are also sensors in eachroom which are designed for ‘occupancydetection’; if no movement is detectedit turns the lights off after a certain timeperiod to save energy. The blinds are alsocontrolled by a Philips Dynalite pushbuttonon a wall panel so at a simple touch theblinds simply open or close.As each stage of the project progressedtowards completion, it was important toremember that all the different segmentsmust be able to operate seamlessly andflawlessly. Thomson concluded by statingthat overcoming the initial constructabilitychallenges had been a learning experiencebut one well suited to the Philips Dynalitesolution and project implementationmethodology utilised. “I am proud that theproject is running well, the complex operatorsare happy and that each new segmentseamlessly joins to the rest of the facility.” nLightnews Vol 13 | 17

Light in actionEntrance to the Fort Irwin trainingbase in the Mojave Desert.Green DefenceEarly results of a lighting management projectat a busy US military training base in the MojaveDesert indicate that Philips Dynalite systemshave the potential to reduce the Department ofDefence’s energy bill by a third.The United States Departmentof Defence (DoD) is one of the largestconsumers of energy in the US andtherefore the world. The broad range ofactivities undertaken by the military andits support operations, use large quantitiesof different energy types in a varietyof ways. In 1995, the DoD establishedthe Environmental Security TechnologyCertification Program (ESTCP) which isdesigned to support the development ofinnovative technologies and promote theirtransfer to a wider commercial market byadopting them for use in federal governmentoffices and other facilities.Operated in conjunction with theDepartment of Energy, each year ESTCPrequests industry to submit projects forevaluation. Projects run under ESTCP,demonstrate systems in operational settingsat military facilities in order to documentand validate improved performance andcost savings. According to Philips ControlsMarketing Manager, Mike Skurla, it is oftendifficult to convince large corporationsor government departments about theeffectiveness of new equipment and systems.“The ESTCP demonstration projects collectcost and performance data in a controlledsituation in order to overcome concernsregarding technical or programmatic risk,”Skurla added.When Philips Controls submitted anapplication, the Army’s Fort Irwin wasnominated as the site to conduct threedemonstration projects. The base is ahighly classified, secured, active facility inCalifornia’s Mojave Desert that carries out awide range of live fire and simulated combattraining exercises. Fort Irwin has an averagepopulation of nearly 25,000.Building 988 at Fort Irwin is used by seniormilitary staff for coordinating the trainingof more than 6,000 personnel that transitthrough the base on different courses. Thesystem demonstration is being carriedout in a portion of the building coveringapproximately 6450 sq. ft. out of the totalbuilding area of 22,000 sq. ft. The areacomprises a conference room, open planoffices, a theatre room, common areas, rest18 | Lightnews Vol 13

ooms and private offices. A PhilipsDynalite portfolio control system wasinstalled in the building along with upgradesof existing lighting fixtures and partialreplacement with new energy-efficientPhilips Lighting luminaires.Private offices around the periphery ofthe building employ ‘daylight harvesting’techniques to provide even illuminationand to save energy. Preset scenes wereprogrammed into the system inconference rooms so that all the lightscould be turned on or off with one button.In addition, the lights could be dimmed toa pre-determined level automatically fordifferent meeting modes.Good illumination can still beenergy-efficientStaff members that work in the buildingare conscious of the need to conserveenergy and have a good code of practicein place where lights are turned off whenpeople leave a room. However, to furtherreduce energy consumption, many of theluminaires had been ‘de-lamped’, whereone of the fluorescent tubes was removed.While this did reduce power consumptionit also resulted in poor lighting conditionsat staff workstations. To compensate, somestaff resorted to bringing in their own desklamps which pushed energy usage back up.Philips Controls Project Manager, OsvaldoVelarde said the aim was to demonstratethat the building could have better lightlevels in the different functional areas of thebuilding and still use less energy. “Preliminaryresults are very positive and indicate thatwe could be reducing the DoD’s electricitybill by 30 per cent,” added Velarde.Securing accessThe greatest challenge of the project wasgaining access to the building where theteam would be working. Since Fort Irwinis a continuously operational military base,a major requirement was to minimisedisruptions to normal working routines. Itwas determined that the best time for thework to be carried out was overnight whenfewer staff are on duty. “We had to work oddhours,” Velarde said. “We started our workingday between 15 hundred and 19 hundredhours in the afternoon, depending on whichpart of the building and which day of theweek and finished between three hundredand four hundred hours in the morning.”The list of people to be working on siteand in the building on a particular day hadto be submitted in advance. It was also arequirement that everyone had to carrytheir individual clearance documents withthem at all times.Another requirement of the project wasthat everything had to be completed in thedesignated shift. “We couldn’t just turn upand do some work and then say we’d comeback the next day,” said Velarde. “Every dayhad a work plan that stated what was to bedone each shift. All equipment was takenaway and we ensured there was no dust orleft over cables lying around so that peoplewould not notice we had been there.”Serendipitous faultThe lighting controls were installed on aseparate network and isolated for securityreasons from the DoD operational ITinfrastructure. This isolation enabledthe team to install a gateway that bychance allowed Velarde and his team todemonstrate a key feature. Project Engineer,Matt Helm, had been on site commissioningparts of the system for a week when hereceived a call as he was about to board aflight home to Chicago. Fort Irwin statedthere was a problem in the conferenceroom used by the senior military staff. Assoon as he landed, Helm connected via theInternet into the DyNet system in Building998 and within five minutes had it resolved.“While everybody knew there was anissue,” Helm stated, “they also all knew thatwe got it sorted in a matter of minutes.It was very attractive and impressive tothe Fort personnel because they knew itusually took at least an hour to get specialisttradespeople on-site.”The Philips Dynalite system installed at FortIrwin has met the aim of ESTCP by showingthat energy savings can be made whilemaintaining safe and comfortable workingenvironments. Velarde stated that he hadbeen told that the building supervisors forother parts of Fort Irwin had indicatedthey would like to have a Dynalite systeminstalled after seeing the effectiveness andease-of-use of the installation in Building998. Philips continues to work with ESTCPand other organisations to develop systemsthat will help reduce federal energy costs. nThe façade of the Fort Irwinadministration building.Lightnews Vol 13 | 19

Industry insightFacilitating the perfect meetingroom environment with userinterfaces, lighting and equipment.Managing meetings forcomfort and productivityProviding the perfect meeting room-equipped with projectors, audio-visualequipment, HVAC, blinds and lighting – to provide both comfort and productivity,features highly in the ‘must haves’ of users and facility managers in commercialbuilding environments. Phil Main, Global Product Marketing Manager, PhilipsDynalite, reviews the best ways to manage these separate elements to get a betterexperience and result for all.20 | Lightnews Vol 13The key to this offering is the userinterface – that point of contact betweenthe user and the systems installed. Thecontrol of equipment and facilities providedin a modern meeting room can be dauntingto the visitor who is unfamiliar with thesystem setup. The choice of interfacesavailable can itself be intimidating, rangingfrom a basic remote control, through totouchscreen panel or tablet PC. The optionson the interface should be intuitive, selfexplanatoryand give the expected resultwhen operated.The ideal user interface will have clearlylabelled ‘buttons’ on one device that willintegrate all of the installed systems andenable a visitor or regular user to operatethe facilities quickly and easily without havingto locate the airconditioning, lighting, blindsor projector controls individually. For moreexperienced users of the room, the decisionto use advanced options to access specificsettings should be equally as straightforward.Incorporating the user interface intonetworked management serviceswill facilitate optimal room usage.Communication between the facilitiesmanager and presenter via a graphicaluser interface can be advantageous toboth parties. For the facilities manager,notification to the occupant of servicessuch as meal delivery can be conveyed andat the conclusion of the meeting, roomscan be taken to an energy-efficient stateand cleaning services requested. Conversely,should the presenter require assistance,the user interface can be a useful tool tocontact the facilities manager.Scheduling calendar software can furtheraid energy-management by coordinatingmeeting room bookings and availabilityof resources. If the room is booked,the facilities can be automatically set to‘meeting’ status and conversely turned offat a preset time after the conclusion ofthe booking. Occupancy sensors can beprogrammed to override this feature ifthe meeting runs overtime, and also keepon external corridor lighting to allow safeegress from the area even after hours.Should the room be required on an adhoc basis, communication with facilitiesmanagement via the user interface canactivate the room.Lighting control systems for meeting roomswill need to consider the position of thespeaker, the use of audio-visual equipment,the location and seating arrangements of theguests. Alternative preset compositions forlighting, blinds. HVAC and equipment, basedon the room’s configuration reduces thecomplexity for the presenter to establishpresentation conditions.Communication is the key to a successfuland professional meeting. Intuitive userinterfaces allow the presenter to optimisethe meeting room environment at thetouch of a button, while ‘behind the curtain’,facility managers coordinate services andequipment to maximise room usage andenergy savings. n

The modernstructure of their new house is hiddenbetween two rows of three-storeyterraces and further concealed by a grassroof and a California-styled garden. Thehomeowner, who is also a successfulproperty developer, faced a daunting task inobtaining planning permission.Work on the project began in 2008, withsignificant time spent detailing all theelements that were to be part of thehome automation system. The homeownerwanted all the lighting, blinds, heating,cooling and audio-video equipment to beintegrated under Philips Dynalite control. Theintegration with the heating system requiredbespoke coding by the experienced installersand specialist consultants familiar with thePhilips Dynalite equipment and software.Environmental designAccording to Will Brocklebank of Faceto-FaceDigital, the company responsiblefor the design and commissioning of thePhilips Dynalite controls, the opportunityto work on a house “from the ground up”was an unusual experience. “We mostlywork on projects where modern technologyis added while renovating classic Londontownhouses,” he said. The large house inEnsor Mews covers more than 5,000square feet on two levels, surrounding anentrance courtyard with automated vehicleaccess gates.To minimise the environmental impact ofthe house, twin ground-source heat pumpsare used to drive the underfloor heatingsystem. Integrating all the elements of thebuilding’s HVAC system into the automationcontrol required a good deal of ingenuityfrom the design team. The engineers fromFace-to-Face Digital had to write routinesfor every aspect of control at the deepestmachine-code level.The release of upgraded software for theaudio-visual system meant that the homeentertainment equipment could be fullyintegrated into the automation system.

A DNG100BT Ethernet gateway wasinstalled in the house to allow monitoringof all the activities of the system. Face-to-Face can also make changes in response tothe homeowner’s requests. According toBrocklebank, such support is vital to thesuccess of a project as complex as EnsorMews. “We respond to questions from theclient about day-to-day operation of thesystem,” he said, “but we also can workwith the mechanical engineering companywhen there is unusual behaviour with theirequipment and can direct them to the siteof the problem.”Final commissioning of the Ensor Mewshouse was overseen by AWE Europe Ltd.Paul Mott, Sales Director for AWE, statedthat his company was now becomingdirectly involved with projects at theplanning stages – working with custominstallation companies like Face-to-FaceDigital – providing backup, technicalsupport and training for all the brands theydistribute. “We are seeing more and moredealers wanting to provide lighting controlsolutions that can be expanded to integrateother systems and the Philips Dynalite offerexcels at this,” Mott said. “Even thoughAWE only became the Philips DynaliteVAR last year, we have already run severaltraining courses for new users of theircommissioning software, EnvisionProject,which is very intuitive and reduces time tocomplete projects.”Integration on displayThe homeowner was involved in all aspectsof the project and the quality of the finishedhome is testament to his desire to makesure everything was right.

Product spotlightGet a better result for your projectCommissioning and managing an entire lighting control system in a building is never an easy task, even with the best planning. Even more sowhen third-party providers need to be integrated into the same infrastructure and the task is late in the construction program. With PhilipsDynalite’s EnvisionProject and EnvisionManager software solutions, the process is intuitive, user-friendly and flexible, resulting in significanttime savings, reduced costs and risk for all project delivery and operational stakeholders.EnvisionProjectSince EnvisionProject was first launched in2010, the commissioning software has beenwidely acclaimed by industry for both its easeof implementation and intuitive configurationprocesses. Experienced users saw reductionsin their commissioning times of a minimumof 40%! Key features of EnvisionProject arethe icon-driven menus and commissioningtemplates to deliver a streamlined, functionallighting control system.The next software version, v1.7 ofEnvisionProject will take these advantagesone step further by continuing to simplifyand expedite the commissioning processwith greater flexibility to incorporatethird-party product/systems providers. Byextending the capabilities of the gatewayinterfaces, the EnvisionProject softwareis now able to connect to third-partyprotocols such as KNX and Lon andcontrol services such as HVAC, audio-visualand blinds. (See also Somfy blindintegration possibilities mentioned in thisedition of Lightnews).EnvisionManagerOnce installed and commissioned, effectivemanagement of the system is vital. Anunsung hero for the building supervisor tomanage the building, is the Philips Dynalite’EnvisionManager software. As the namesuggests EnvisionManager allows themanagement, modification and reportingof lighting control systems and third-partyproducts and systems. The user interfaceof the software provides an overview ofthe entire building, allowing the managerto make adjustments to networked devicesand functions to maximise energy efficiency,schedule maintenance and respond tochanges in occupancy behaviour, whilstalways considering the balance required interms of user comfort and productivity.EnvisionManager has the capability toprovide a range of reports including energyconsumption, lamp life and fault finding andoccupancy patterns. With this data, historicalreferences and audit trails can be establishedto ensure the building is safe, energyefficientand comfortable for its occupants.The next release of EnvisionManager v3.5will be an important component of PhilipsDynalite’s lighting control solution and willincorporate four key features to facilitate:• more efficient commissioning times• improve occupancy safety• perform sensor calibration and• monitor energy consumption in zones.Off-site commissioning:The user interfaces of EnvisionManager canbe designed off-site prior to installation.With the off-site commissioning feature,the downtime lost to travel or delays inconstruction can be overcome bygenerating graphical user interfaces andconfiguring devices prior to going on-site.Once on-site, the engineer can scan thenetwork to establish communications,select a device and synchronise it with thesoftware via serial number identification.Client training and acceptance of theuser interfaces can be facilitated prior toinstallation, reducing the time to final clienthandover, with resultant cost reduction andcustomer satisfaction.26 | Lightnews Vol 13

Area/corridor cascading:Building managers will have the capability oflinking lighting control of offices to corridors,corridors to foyers and reception areas.While an office is occupied, the corridorlight will remain on, as will the lights for thefoyer and reception. As each area is vacatedsequentially, for instance at the end of theworking day, the lights will switch off after apre-determined delay as each sequential areais vacated, cascading through the building.By utilising EnvisionManager, the buildingsupervisor can link corridors and officespaces in which to operate the cascadingfeature. Not only does this remove the onusfor the last occupant to turn out the lights, italso maximises energy savings by using onlythose lights that are needed.Sensor self-calibration:In a large project, many sensors are installedand cannot be easily calibrated until theinterior fitout is complete. Calibrating thesensors is performed at night, with all thelights on – this represents the ‘high’ statefor the lamps with no ‘daylight’ contributionfrom building windows and openings.Similarly, turning all the lamps off is to setthe ‘low’ point. During normal operation thesystem will now dim the lighting whenevernatural daylight entering the building causesthe measured light to rise beyond the ‘high’level. EnvisionManager is now able to initiatea calibration to ensure that the sensors anddimming functions are at the correct levelsensuring occupant safety.Scalable energy consumption:A key feature of EnvisionManager is theability for the building manager to ‘zone’particular areas of the building. Zoningallows for a suite of offices to be ‘grouped’together even when they are not physicallyin the same location. The advantage of thisfeature is the ability to monitor and reporton energy consumption, particularly if abusiness utilises disparate locations withinthe building. Not only can the buildingmanagement system work toward greaterefficiency, but can also monitor, minimiseand report on their energy costs andconsumption. A good example of this wouldbe a cost centre such as R&D or Accountingthat has teams dispersed onto differentfloors in a building. With reductions inenergy consumption and occupant safetyand comfort enhanced, the installation andcommissioning time is accelerated.The combination of these features is setto provide the building manager witha powerful set of tools to improve theoverall management of the premises. Thefully integrated end-to-end solution ofcommissioning software available throughEnvisionProject and EnvisionManager isgiving the installer and user a streamlined,easy to use system. The added featuresof third-party integrators, managementtools and improved user templates andicons included in the forthcoming versionreleases, will make the commissioning andmanagement process truly visionary. nEnvisionManager’s MapView,showing an office floor inreal time operation.Designing a lightingscene in real time acrossmultiple controllers withEnvisionProject.Lightnews Vol 12 | 27

Product spotlightMaximising the use of natural lightingis a key strategy and opportunity toimprove energy efficiency and reduceenergy consumption“”Balancing lightand energy usageLighting and airconditioningconsume the largest portion of allpower used in commercial offices. As partof green building and sustainable designprinciples, modern commercial buildingsare designed with a lighting ‘wattage budget’which sets an upper limit on the numberof watts that can be consumed per squaremetre of floor space.Maximising the use of natural lighting is akey strategy and opportunity to improveenergy efficiency and reduce energyconsumption, but this needs to be offsetby the needs for an occupants comfortthrough the reduction of glare from outside,as well as heat penetrating the building. Thelast point can also impact on the energyusage of the airconditioning system thatmay need to use additional energy to keepthe occupants comfortable. According toDaniel Walker, Product Manager with PhilipsDynalite, it has been easy to control artificiallight, but far more difficult to coordinatethis with natural light penetration intothe building, so that the illumination in aroom is constant no matter what time ofday and that the reduced lighting energyis not offset or overcome by increasedairconditioning energy costs. “PhilipsDynalite worked in partnership with Somfyon a development project to write codeinto one of our network gateways sothat it could communicate direct to theirsystem making the integration process a lotsimpler and bringing a finer granularity ofcontrol,” Walker stated.”This allows buildingowners and operators to not only get thecorrect balance in terms of the right lightingconditions but also to maximise the balanceof energy used overall.”There is an obvious synergy betweenthe systems controlling blind positionand lighting levels within buildings, so it istherefore essential to integrate both systems.The Philips Dynalite DyNet softwareprotocol has been able to send messagesto Somfy motors for many years, butpreviously could only send simple ‘start/stop’commands. The result of the collaborationbetween the industry leaders now meansthat a Somfy blinds motor can receive veryspecific instructions such as ‘drop down10 cm’. The unit was first demonstratedat Lightfair in Philadelphia earlier this year.“We have put the Somfy drivers within ourproduct so that within the commissioningsoftware we can say to a gateway that “youare talking to a SOMFY motor” and it willautomatically repopulate itself with theappropriate commands,” said Walker.For example, a Philips Dynalite occupancyand light level sensor mounted on the ceilingcontinually measures occupancy of an areaor zone and the amount of sunlight enteringa room. By comparing this to the desiredlighting lux level programmed into the unit,the appropriate position for the blinds andthe amount of artificial light can be set.During the course of a day, the levels ofsunlight entering a room increase, however,so too does the glare and heat. In themorning, the blinds will be gradually opened(they can be closed at night to retain heat)and lights dimmed, but at noon, the blindsmay be closed again and the artificial lightsat maximum. “So with one sensor we aregoing to be able to drive the lighting andthe blinds together,” Walker added, “We’rebringing all these elements back to thePhilips Dynalite system and then balancingmultiple variables to achieve the optimumlighting and energy management results.” n28 | Lightnews Vol 13

Ultrasonics – costs down,efficiency upUltrasonic occupancy sensorsenable developers to reduce thecost of a lighting control system and gainsignificant energy usage reduction forbuilding owners.Early lighting controls were basic switches onthe wall that could turn on or off. They reliedon the user of that space to turn the lightsoff when they left the office or area to saveenergy. If not switched off then no energyis saved and this adds additional cost suchas energy usage and maintenance like relampingat an earlier time than required. Lateranalogue and digital timers were developedto provide basic automation for switchinglights on or off, these were cumbersometo use and assumed regular “normal hoursof work” in a building. The next advance inautomated control was occupant presencedetection which allowed lights to be turnedon automatically when someone entereda room. The first presence detectors werepassive infra-red (PIR) devices which offeredthe ability to scan small areas of a space orroom. When coupled with an internal timeoutfeature, the lights could be automaticallyturned off if no presence was detected aftera period of time.PIR sensors have limited detection range,sensitivity issues and require a line of sightto any occupant. This last point can result inoffice staff potentially being left in the dark.Ultrasonic sensors are the latest technologystep used to control illumination inbuildings. The new multifunction sensorfrom Philips Dynalite, combines fourdetection technologies into the one device– ultrasonics, the traditional PIR, lightinglevel and infra-red receive technologies. Thislast feature enables the sensor to adjust thelocal light settings by a hand-held remoteunit. The sensor can automatically tunethe lighting control system to gain extraenergy savings by dimming the lighting whenenough daylight from external sources orextra lighting above standard requirementsthrough overdesign or no presence isdetected within the area.“With the four sensory disciplines in thedevice, there is an opportunity to perform asequence of logic so that multiple functionscan be performed by the one device.Our company is the only one that doesthis,” according to Daniel Walker, ProductManager at Philips Dynalite. The sensor canbe programmed so that when occupancy isfirst detected it also determines the naturallight level provided by sunlight. The sensorcan then instruct the lighting controller tosupply the necessary artificial illuminationfrom the light fittings within the area. Allthis happens in less than a second andremoves the need for multiple sensors to bemounted in a room to separately performthe different functions.Ultrasonic sensors actively propagate highfrequencywaves which reflect off surfacesand objects and the sensor records thereflection back to the device as a referencepoint. Any change indicates positive motiondetection and the lighting managementsystem responds.The major benefit of the wave reflectionsis that the wave can wrap around cornersand bounce down into office cubicles; thisremoves the problem of people becominginvisible to PIR sensors when they are notin direct line-of-sight of the sensor. Walkerstated, “Ultrasonic sensors were installedin an office changing room. We found thatin practice the standing wave was bouncedoff different surfaces and spread out. Wewere able to use just one sensor to controlall the lights in the change, shower andlobby areas, not three as would be requiredwith traditional PIR occupancy sensors.”Such an arrangement provides not justbetter occupancy sensing performance,but also real cost savings in installation andcommissioning, providing a faster pay-backfor the end-user.Different levels of ultrasonic sensitivity canbe set to allow for situations where the useris only making slight movements in the taskthey are performing in the area they workin, such as keyboard strokes whilst sitting inthe one position. This allows for the lightingand other services in a building space toremain on even for a single user after hours,creating a comfortable, safe and productivework environment.The new sensors can be linked withother sensors and lighting load controldevices, making this a system solutionwith large scalability opportunities.Being digitally addressable allows thedevices to be remotely configured bythe control computer. This removes theneed to manually adjust switches andpotentiometers directly on the deviceitself as is required with other competitorsolutions, which adds time and cost.Ultrasonic sensors have a much largerscanning range so fewer units need to beinstalled on the ceiling and this reduces thecost of both installation and commissioningand this can be 15-20% for sensor devices.Operational energy savings for a buildingcan be up to 55-65 per cent because of thecombined technologies being used. “This isa great benefit to the developer in reducingcapital costs, as well as leaving a bettersystem installed that will provide the ownersor occupiers with ongoing energy savings.” nLightnews Vol 13 | 29

Light in actionPreparing one of the operationalareas of the Standard Bank facilityin Johannesburg.Banking on an above Standardsolution gets 50% in savingsMaximising comfort as well as minimising energy are the basis for any controls solution in the office spacetoday. But for one major South African banking facility, both security and safety were added to the primaryrequirements for their recently implemented lighting system. The local Philips Dynalite distributor was able todemonstrate that employees within the facility could have safe, illuminated pathways to internal workstationswhile at the same time significantly reducing energy costs by effectively controlling the system right acrossthe facility at all times of the day for all building users.When South Africa’s StandardBank released a tender for theconstruction of a facility to house someof its operations, one of the majorrequirements of the project was to optimiseenergy efficiency in the building. TeslaAutomation was chosen to supply, install andcommission the lighting management systemthat is possibly the largest networkedlighting system in South Africa.The total budget for the project, includingconstruction, fit-out and computerhardware, was approximately 4 billion Rand(400 M Euro). Located in Johannesburg, thebuilding comprises offices, computer roomsand common areas, covering approximately50,000 square metres of flooring. Whilethe core of the Philips Dynalite technologyallows for integration with other buildingservices, the design from Tesla was for astand-alone lighting management system.“We originally proposed integration to thebuilding network system for individual lightcontrol, but for security reasons the bankdid not want anyone to be able to accessthe data networks,” said Zoran Paunovic,Managing Director of Tesla Automation inCape Town.Tesla has been the Philips Dynalite valueadded reseller (VAR) for southern Africasince 2004 and enjoys good workingrelationships with many of the leadingelectrical consultants and engineers inthe region. The facility is a completelynew building. During the fit-out stage, thecabling for the lighting management systemand luminaires, as well as the light fixturesthemselves, were installed by the electricalcontractor. Paunovic’s team installed all thesmart devices including the controllers,sensors and switches and also programmedand then commissioned the whole system.Paunovic was able to demonstrate tothe lead electrical consultant that Tesla’sproposal was a more cost effective solutionthan any other competitors solution. Inparticular two items stood out, the ease ofconfiguring the system and the minimal needfor reprogramming. Energy efficiency andsustainability were a major consideration inthe planning for the new bank facility andTesla was able to show that its design couldpotentially save more than 50 per cent onenergy consumption.Securing the projectBanks are renowned for their adherenceto security of their systems and restrictingaccess to different parts of the building.Paunovic stated that the only time theyrequired special clearance was when histeam returned to site to make a slightalteration to the configuration and toreplace a faulty device. “We had alreadyfinished our part of the job before thetenants moved in,” he added. “We onlyhad to go back and go through a short listof minor changes which is something youalways have to do on this type of project.”Paunovic said that of all the equipmentthat his team installed, only one sensorout of the 500 was defective and that itwas a simple matter to replace the unit byunplugging the faulty one and replacing itwith a new unit. It was then a simple matterof adjusting the DLight III server software,rather than reprogramming everything fromscratch like some other systems.One of the largest electrical contractorsin South Africa was responsible for the30 | Lightnews Vol 13

approximately 500 M Rand electricalcomponent of the project. With substantialinteraction and flexibility required on siteTesla was able to install and commissionthe lighting management system so that thebuilding was handed over to the client onschedule, within budget and with an abovestandard result.A well lit path to the futureThe operations area of Standard Bank’snewest facility occupies more than half thearea of the building. The space has beendivided into eight separate areas overtwo floors of the building, with each areameasuring approximately 60 by 30 metres.Designing the lighting layout using theDALI and Philips Dynalite’s Dynet protocoltogether made it possible to overcome thelimitations of a DALI only system, wheremultiple areas would normally need tobe controlled separately and no controlsacross “universes” are possible. The DALIonly protocol allows limited amount of“presets”, fade rates, etc. that is common inother lighting management systems, whereasthe Philips Dynalite system takes all theadvantages of DALI and gets a better resultby providing maximum flexibility, scenesetting and scalability.Offices located next to the main buildingutilise energy-efficient T5 luminaireslinked to daylight harvesting sensors thatautomatically maintain the level of 300 lux.Other sensors and controllers throughoutthe building combine to ensure thatworkers moving around in the facility arealways walking in illuminated corridors andcomputer rooms. The luminaires in thecomputer areas have been grouped togetherin batches of lights that provide ‘follow me’lighting: the pathway to a particular suite ofcomputers a person might be working atwill be illuminated, but adjacent areas will beset in energy save mode.The success of the project for Tesla hasincreased the market awareness of its nameand the globally recognised Philips brand.Paunovic concluded, “We are already busytendering on many projects throughoutSouth Africa.” nEnergy efficiency andsustainability were amajor considerationin the planning for thenew bank facility andTesla was able to showthat its design couldpotentially save morethan 50 per cent onenergy consumption.“”Lightnews Vol 13 | 31

Light in actionVodacom’s dynamiccontrols displayThe development of an operations centre for a major South Africantelecoms company provided the backdrop for an innovative anddramatic lighting project that has become an iconic and much talkedabout installation in Cape Town.Vodacom, one of South Africa’slargest telecommunicationsproviders, needed a new facility tomeet the demands of its rapidly expandingsubscriber base and the number of differentservices it offers to them.An existing building near a Cape Townhighway was proposed that had most ofthe required features to accommodate theoperations, but with the one exception beingthat it was too small. However, the size ofthe structure was not a major obstacle. Thedesign allowed additional storey’s to be addedwith little disruption. An innovative modulardesign was developed that doubled the heightof the building.Design considerationsA major part of the project was theconstruction of a massive, dynamic lightwallconstructed of glass panels that encirclesthe building. A major requirement from thearchitect and designer was for the LEDfixtures not to be seen through or reflectedin, the glass panels. Tesla Automationcollaborated with one of the country’sleading LED manufacturer to design thecustom fixture that would be used toilluminate the lightwall. Philips Luxeon RebelLED units formed the basis of the fixtureand were mounted behind the glass panels.This was challenging because the LuxeonLEDs are a very powerful light source sothe positioning of the fixtures behind thepanels was critical to getting the right resultdemanded by the designers.Zoran Paunovic, Managing Director of TeslaAutomation in Cape Town, stated that thedesign for the lightwall panel could havebeen described as being developed by trialand error. “We obtained a sample of theglass and constructed a mock-up of thepanel and mounting box in our office,” headded. “We made several different diffuserSequence showing asample of colours thatcan be 32 displayed | Lightnews on Vol 13the Vodacom lightwall.

There wasa small amount of direct lighting on the glassbut the majority was coming back reflectedoff the building.”The lightwall on the re-developed Vodacombuilding was the first use of exterior LEDson such a large scale in South Africa. Asthe building was close to a major road,concerns were raised about the impactof the structure on the passing traffic.“We had to do a lot of research into theplanning regulations,” Paunovic said, “but wediscovered that the local regulations onlyrefer to billboards, not buildings.”Efficiency is keyThe massive glass panels that form thelightwall measure three by two metres.According to Paunovic, Tesla originallyoffered to have a multi-directional designfor the dynamic movement of the light tocreate the effect of the computer game“Tetris”. While this concept was spectacular,it proved too expensive for the client.The fixtures allow a full palette of coloursto be displayed but since Vodacom wasrecently bought by the international telecomprovider Vodafone, the colour of the lightshas been restricted to the red and whitecorporate colours of the new owner. Thedesign was modified to have only horizontalmovement of the colour changes, movingleft to right and right to left or from thecentre outwards.The lightwall is not integrated with otherbuilding services and is controlled by asingle computer inside the building anda Philips Dynalite timeclock. Operatingfrom sunset to sunrise, the dynamic displayof the Luxeon fixtures is coordinated byPhilips Dynalite LED controllers installedin 37 distribution boards mounted outsidearound the building. Tesla also incorporateda manual override control into the system.Timing throughout the project was animportant factor. Tesla had to ensure all 500fixtures would be ready on time. Assemblyof the lightwall was also dependent on theconstruction of the building because none ofthe support structure could be put in placeuntil the outer walls had been rendered andpainted. The whole wall was painted whiteto maximise the reflection off the walls andthrough the glass panels.Another design criteria was for thebuilding to have minimal environmentalimpact. The LED modules used for thelightwall are all ultra-efficient colourrendering units. Throughout the remainderof the building, LED lighting is used in allthe corridors. To further reduce energyconsumption, extensive use of occupancydetection is implemented.A bright futurePaunovic stated that the Vodacom lightwallhad already generated a great deal ofinterest throughout the South Africanconstruction and design industries. Tesla hasbeen approached with more proposals thatutilise the special Luxeon Rebel fixtures. Thecompany has also been asked to advise ontheir method of installing the luminaires sothat the source could not be seen.Tesla became the Dynalite VAR in SouthAfrica in 2004. Since Dynalite’s acquisitionby Philips, Paunovic has also taken on otherranges within the Philips family, includingColorKinetics. Tesla will be working closelywith Philips South Africa to leverage thePhilips brand name and promote theDynalite lighting management system andColorKinetics luminaires in all appropriatefuture projects. nLightnews Vol 13 | 33
