system. Further requirements included run- ning cost efficiency, low maintenance and control of luminaires. All office lighting and outdoor lighting, and the lighting manage- ment system were supplied by Lighting Innovations Africa. The offices, meeting rooms and common areas are illuminated by 5800 Pallure LED light fittings, locally manufactured at LIA’s Port Elizabeth factory.The Pallure is a stylish, perforated recessed fitting designed specifi- cally for office illumination. To meet the strict control criteria request- ed by the client, the ENCELIUM light man- agement system was selected. It is a DALI based system that enables comprehensive control of the whole lighting system from anywhere via remote access and makes use of daylight harvesting, occupancy control, personal control and smart time scheduling, the combination of which can deliver energy savings of up to 75%. ENCELIUM is a flexible and powerful way to manage a lighting space. It is the only lighting control system that can gather data from a range of lighting component suppli- ers to tailor lighting usage with changing requirements – making any building fit for the future. The system consists of a central service unit that enables users to control the lighting by floor, zone or by individual fixtures. The sensors, switches and fixtures are all wired back to an energy control unit (ECU) via the DALI bus.The ECU controls the lighting using a combination of six strategies to save between 50 to 75%.The Polaris 3D is the graphical interface that views the build- ing in 3D, providing various thermographic views to show status, energy consumption and all system information. Each ECU is equipped with four DALI channels that en- able it to control up to 256 fixtures and 256 sensors or switches. For the outdoor installation including pathway lightings, tree uplighting, garden lights and façade lighting, LED was used throughout.e in the area.”
