Lighting in Design Q2 2023

the city. • In a Jakarta trial by Indonesia’s Ministry of Energy (MOE) Research and Development Agency, more-efficient street light lamps combined with dimming and scheduling capa bilities yielded 59% in energy savings. Plus, Jakarta was able to detect electricity theft and reduce maintenance and operational logistics of their outdoor lighting system. • The City of Paris replaced 80,000 light fixtures with a multivendor open system. In addition to saving 35% in both energy and capital expenses, Paris is using its citywide lighting network as the basis for developing Smart City applications. In Sénart en Essonne , a four-city area 35 km south of Paris, an outdoor lighting system has helped reduce the area’s operating budget and maintenance costs while increas ing road safety. • A state-of-the-art outdoor lighting system controlled by smart technology provides Sau di Arabia’s Riyadh and Mecca with real-time outdoor lighting control. Now, the cities can remotely turn lights on and off, adjust their intensity through automatic programming or sensors, detect energy leakage or possible ca ble cuts, and receive an alarm for any unauthor ised opening of a power supply cabinet door. • Milton Keynes, 45 miles northwest of Lon don, modernised its outdoor lighting net work by installing smart electronic bal lasts and enterprise monitoring software. The city’s lower-wattage street lights – paired with a control network and various sensors – allow lamps to adjust illumination automatically for longer life and less light pollution; cast higher-quality light; and help the city satisfy various EU and worldwide directives to reduce energy usage.

lighting control. • Compliance with European Union, worldwide, and local laws and directives for reduced ener gy use, CO 2 emissions, and use of high-pollut ing components such as mercury. • An infrastructure for efficiently controlling future technologies, including Smart City and Internet of Things applications. Real-world examples • Norway’s capital, Oslo, was one of the first cities to deploy a large-scale intelligent, open standards-based outdoor lighting network. Data from traffic and weather sensors and an internal astronomical clock are used to auto matically dim some street lights, thus reducing energy use by 62%, extending lamp life, and lowering replacement costs. • Elsewhere in Norway, Øvre Eiker, famous as the site of the first major Viking gold find, in stalled a dynamic outdoor lighting system with PLC transceivers and controllers that reduced street light energy use by 45%, cut mainte nance costs by 35%, reduced CO 2 emissions, and helped meet EU directives. • Using the new technology, Quebec City saved 30% in energy use, reduced maintenance and inventory costs, increased public safety, and beautified the city’s historical district. • After installing electronic dimmable ballasts and enhanced fixtures controlled by technol ogy, the densely populated Chinese cities of Dongguan and Shenzhen saved an average of 52% in energy costs; identified cable theft; and reduced the number of maintenance people. • Dublin completed a successful project replac ing 1300 light points with electronic dimmable ballasts controlled by CMS cloud-based soft ware. With average energy savings of 35%, Dublin approved the solution for the rest of
