Smart lighting reduces energy costs by 71% for Penthéréaz
Supporting Flanders’ Smart Region Journey
Fluvius, which manages 1.2 million lighting points for 300 Flemish cities and municipalities, has been on a mission to convert them all to LED technology since 2015 with the ‘All Lights to LED’ plan. In 2024, over half of Flanders’ lighting points - 600,000 luminaires - had been equipped with LEDs. That has driven a 30% reduction in energy use since 2015, which equates to around 30,876 tonnes of CO2 emissions per year. By completion, the transition is expected to save up to €54 million annually on energy costs. While much of the energy saving is due to converting the light fittings from legacy systems to LED, another wave is down to embracing smart technologies. By using a smart lighting system in combination with controller nodes to connect thousands of lighting points, Fluvius enables cities and municipalities to dim or switch off the lights during the quietest hours of the night to save even more energy. ‘All lights to LED’ is a long-term project and we have been working with Fluvius every step of the way. More than 300,000 street lights are now connected to the Schréder EXEDRA platform, helping municipalities across Flanders to save energy and money by optimising lighting.
The picturesque town of Penthéréaz in the Gros-de-Vaud region of Switzerland, decided to upgrade to a smart lighting system to reduce energy costs and light pollution. They chose the FLEXIA QUERCUS, a versatile luminaire with a plant-based design that brings a touch of nature to the heart of the town and is an DarkSky approved luminaire. Featuring a flat glass protector, it directs all the light to the ground with no light spill. All of the FLEXIA QUERCUS luminaires in the town are controlled by the Schréder EXEDRA lighting control management system that adjusts the lighting according to real needs. To ensure that the lighting met the expectations of the local community, tests were carried out in four streets. Feedback from the residents was invaluable in determining the most appropriate lighting levels. Based on these insights, a dimming schedule was implemented, delivering substantial energy savings of over 70%. Thanks to the intuitive interface of Schréder EXEDRA, the local authorities can easily adapt the lighting to events taking place in the town. For example, on 12th August 2024, the town switched off the lighting for the night of the Perseids to give residents the best possible view of the meteors in the sky.
In addition to reducing energy consumption, Schréder EXEDRA also provides real-time monitoring, with instant access to the status of each connected luminaire, giving Fluvius a much better overview of its inventory. This improved visibility will enable Fluvius to extend the lifespan of assets, maximise uptime, and further reduce intervention costs - helping cities to achieve their circular economy goals.
We’ve already switched 70% of the lights in Bruges to LED, greatly reducing our energy consumption. We are also able to dim the lights to a level of 30% or even 50%, something we were not able to do with the regular street lights. Mercedes Van Volcem Alderman for Bruges Public Domain (2019 - 2024)
