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 comfort.is 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
