ONE OF the largest European power-over-ethernet projects has opened in Copenhagen.
Over 400 LED luminaires at the ‘smart office’ of the Albertslund Municipality are connected, powered and communicated with using Ethernet cables. The installation allows the office workers to personalise their lighting using a smartphone app while giving the building’s managers insights into energy use and space utilisation.
It’s the first PoE project in Scandinavia.
The connected lighting system uses Cisco PoE switches to transmit power and data over standard ethernet cables. Data acquired by the sensors – including occupancy detectors – in the lighting fixtures provides information about the building's use and operations. Data, such as light levels, energy consumption and room occupancy, helps managers to optimise both the energy use and the office space.
The smart office represents a milestone in the EU-funded ‘Lighting Metropolis’ initiative, which plans to make the whole of greater Copenhagen a laboratory for connected lighting. The Albertslund Municipality smart office is one of the initiative’s first projects and joins more than 25 other demonstration projects under development, from lighting for psychiatry to traffic lights and lighting for schools.
‘We’re looking at an exciting future where we will see smart buildings that provide valuable information on their use. Light typically accounts for about 40 per cent of a building's electricity use.
'Switching to connected LED lighting can result in electricity savings of up to 80 per cent as well as lower maintenance costs, gains in productivity and last, but not least, an optimised working environment,’ says Astrid Simonsen Joos of Philips Lighting, which supplied lighting system.
Danish telecoms company TDC Erhverv installed the system and other technologies, including Wi-Fi and video conferencing equipment, and led the project’s overall management.
- Lux is organised two conferences on Lighting for Health and Wellbeing in 2018. The first takes place in Newport Beach, California on 18 July and the second takes place on Wednesday 26 September 2018 in London. For more information on both events and to view the full programme, click HERE.
