NETWORKED LIGHTING Light years ahead Cray Valley Components and Integrated System Technologies (IST) highlight the opportunities that exist in providing the next generation of networked lighting via IST’s iDrive Power and Ethernet (PaE) lighting system. T he commercial built environment has constantly changed down the years. However we are entering a stage where change is accelerating faster than ever before bringing multiple advantages to building owners, those working in them and delivering oppor tunities to contractors. The intelligent building concept connects multiple devices, people and processes to drive new experiences and better business outcomes by converging multiple, disparate building networks, systems and ser vices via a secure and intelligent network. Such systems help unlock new experiences and efficiencies whilst lowering building operating costs over the typical 50-year lifetime of a building. Different building systems, such as lighting, heating, air conditioning, IP, VoiP, as well as physical security and access control, can now work together. They can adapt to users’ needs in real time to make spaces work better for individuals and groups. This approach breaks through silos of independently operated building systems to make it easier to automate all building ser vices. Through digitisation, it becomes possible to put sensor data into databases that can be analysed to gain deeper insight into how employees, customers, and guests are using spaces, allowing improved business decisions to be made about use of real estate such as room, floor and building occupancy. One of the most compelling of these next generation solutions is in connected lighting. 18 | September 2017 Ethernet-based low voltage lighting ‘Installation companies that have strong relationships with their end-user clients will benefit most from these new ideas.’ Eddie Brady, business development executive at Cray Valley Low voltage LED lighting is playing an increasingly important role within intelligent buildings, driven by the adoption of Category 6A Ethernet cabling to luminaires. Low voltage lighting marks a new era and new opportunities for the cabling industry, as lighting projects involving hundreds and thousands of luminaires and sensors can only be deployed viably and reliably using wired solutions. LED luminaires offer three compelling reasons for inclusion in the intelligent building. T  hey consume less electricity T hey generate less heat T hey are 100% dimmable There are also other advantages as the systems offer enhanced optical wireless networking. The recent development of optical Li-Fi networks, can theoretically achieve speeds of up to 226Gbps. Li-Fi networking also transcends the limitations associated with Wi- Fi, such as limited bandwidth and potential carcinogenic effects. Other advantages include a typical 50,000 hour life-span for the luminaires and centralised LED drivers that reduce maintenance costs. Also, the reduction in the amount of energy used for lighting can directly impact the reduction of HVAC costs. For every three watts reduced in lighting, there is a corresponding one watt reduction in HVAC load. Low voltage, smar t lighting also provides significant health and safety benefits, allowing easy maintenance and office reconfiguration. Advanced emergency evacuation wayfinding uses LED luminaires to flash and change colour to aid employees to locate the nearest and safest exit route. Creating new user experiences via lighting services With an IP backbone linking multiple building systems in a smart, connected architecture, future lighting systems will improve safety, comfort, productivity and business deliverables. There are also many new services that can be offered by low voltage, digital lighting solutions. With many organisations using ‘hot-desking’, employees can customise light in their spaces to match what they are doing and to suit their personal preferences. A smart, connected workspace can even automatically carry over an employee’s pre-set IP phone preferences and automatically log them into collaboration tools. In shared spaces, the same digital architecture supports multiple functional working zones that can change to suit a new employee, team, or task. Another hot topic right now is human-centric, healthier lighting. Users will be able to control lighting intensity and colour temperature in every work space, alongside other factors to adapt to the needs of occupants. Circadian rhythm lighting which mimics natural light cycles can increase productivity up to 16%, aid patient recovery in hospitals and improve le &r662FvFƖvFr6WF066&RFVw&FVBvFFvF6vvRBvfFpƖ6F2FB6V7BvFVVW>( Bf6F'>( W'6
