INTELLIGENT BRANDS // Cabling Integrating building lighting with IoT using PoE Structured cabling vendor Siemon illustrates how Power over Ethernet is integrating lighting with IoT systems. specify, install, and manage the many components in a Power over Ethernet lighting system, most customers rely on a lighting engineer or architect to design a reflected ceiling plan for the building space. Power over Ethernet lighting solutions globally illuminate over one billion square feet of commercial space today. Explosive growth is predicted for the smart lighting industry because, in addition to having the potential to reduce energy costs by up to 90%, these systems lower capital lighting investment, improve safety and comfort, and integrate with all IoT- enabled building automation systems. In fact, Gartner predicts the number of smart lighting deployments to grow from 46 million units in 2015 to 2.54 billion units in 2020. Considered an integral component of the Internet of Things, smart or intelligent lighting solutions consist of a system of lighting fixtures, which can be controlled, monitored, and powered over one centralised network. Deployment of smart lighting systems over balanced twisted-pair cabling is becoming increasingly popular due to the ease and benefits of using Ethernet communication for control and deploying remote powering technology, such as 60W Power over Ethernet, to safely energise the lighting grid. These systems are commonly referred to as Power over Ethernet lighting. To maximise efficiency, Power over Ethernet lighting luminaires typically utilise light emitting diode technology, which offers the benefits of lower www.intelligentcio.com power consumption and less heat generation than other luminaire design alternatives. The power saving opportunities and deployment flexibility associated with smart Power over Ethernet lighting systems are significant and are changing the landscape of structured cabling design. Power over Ethernet lighting systems are sophisticated and rely on a well-designed infrastructure of high performance balanced twisted- pair cabling, network electronics, and software connecting and communicating with IP addressable luminaires, dimmers, sensors, and controllers to deliver maximum performance, comfort, and energy savings benefits. Because of the wide range of expertise needed to Power over Ethernet lighting opportunities alone comprise 35% of the possible savings in capital expenditure in an IoT enabled building. In addition, a comparison performed by Cisco of the upfront labor and installation investment and upfront hardware and software investment costs between traditional fluorescent, traditional LED, and 60W UPOE3- enabled LED lighting deployments in a 3,000+ m2 building in New York City, demonstrates that Power over Ethernet- enabled lighting systems have the lowest cost of ownership. Unlike traditional lighting systems supported by 120V 60 Hz or 230V 50 Hz alternating current circuits running over 12-14 AWG electrical cable, Power over Ethernet lighting is deployed over user-friendly balanced twisted-pair INTELLIGENTCIO 33
