Smart and Circular Lighting for Arnhem Municipality
T
RILUX partnership Delivers Intelligent and Sustainable Lighting for Centraal and Musis Parking Garages UK, March 2025 – The municipality of Arnhem has embraced a smarter, more sustainable future
with the modernisation of lighting at its Centraal and Musis parking garages. Working in partnership with ITN, TRILUX provided a cutting-edge, wireless lighting solution that enhances energy efficiency and supports circular economy principles by recycling old luminaires into raw materials for new fixtures. With a strong emphasis on quality, longevity, and sustainability, TRILUX's solution went beyond
conventional lighting upgrades. Integrated smart controls, sensor-based dimming, and wireless communication optimise energy consumption while reducing CO₂ emissions. The project also features a fully circular recycling process, setting a new benchmark for municipal lighting schemes.
A Smart, Wireless Lighting Network A key requirement of the project was the implementation of an intelligent lighting system that adapts dynamically to usage patterns. TRILUX equipped the parking garages with MyMesh-enabled luminaires, creating a fully networked, sensor-driven environment without the need for additional DALI control lines. "The luminaires operate at an energy-saving base level, automatically adjusting brightness based on
real-time occupancy data," explains Martijn den Besten, Business Development Manager at TRILUX. "If no movement is detected, the lighting dims further, and as soon as activity resumes, the system instantly returns to the required illumination level. This maximises energy efficiency while ensuring safety and comfort for users." All luminaires are seamlessly connected to the LiveLink Premium light management system,
allowing the municipality to remotely monitor, adjust, and optimise settings for different parking levels. The result is a high-performance lighting infrastructure that is cost-effective, long-lasting, and environmentally responsible.
Closing the Loop: A Fully Circular Lighting Approach The Arnhem project also demonstrates TRILUX's commitment to circularity. Instead of disposing of old luminaires, TRILUX and ITN established a closed-loop recycling system to recover and repurpose materials. "ITN collected and transported the decommissioned luminaires to the Recycle Service Center in
Amsterdam, where they were fully dismantled," explains Raymond van Dijken, Sales Manager at TRILUX Benelux. "Optics, housings, clamps, ballasts, electronics, and lamp sockets were separated and processed for reuse. The housings and optics were recycled into high-quality granulate, which is now being used as raw material in our Zaragoza factory to manufacture new waterproof luminaires." By integrating smart controls and circular economy principles, the Arnhem municipality is reducing its
environmental footprint and setting a precedent for sustainable public lighting projects. With long-term efficiency, flexibility, and sustainability at the heart of this initiative, TRILUX continues
to drive innovation in smart, responsible lighting solutions—helping cities transition towards smarter, more sustainable urban environments. For further information about TRILUX’s refurbishment solutions visit

www.trilux.com Case Study: The Range Chooses FUSION Sustainable Water Heating from Adveco I
n January 2024, market-leading mechanical and electrical contractor WM Building Services Limited (WMBS) secured the contract for the new build of a retail goods and produce distribution centre for The Range. One of the UK’s most recognised and fastest growing leisure and garden centre retailers, The Range has more than 200 stores and has recently acquired both the Wilko and Homebase brands, intending to rebrand as many as 70 of the latter’s properties as new The Range Stores. As key function of this planned expansion, the new
distribution centre for The Range & Wilco would be located in Stowmarket, Suffolk. With 356,600 square metres of warehousing space and the ability to manage 200-plus trucks, the site would be considerably larger than its typical stores. This new building was also to align with the retailer’s aims of increasing sustainability and reducing lifetime carbon emissions from its properties. Envisioned as a two-phase project, the build of the
distribution centre would commence with a clearly outlined base build and then a full package fit-out of services within the limits of the building. External attachments to the site building, such as packaged plant
rooms, would not be a viable option for this project. Part of the building specification required the provision of domestic hot water (DHW) for canteen and kitchen facilities within the distribution centre building to support the expected 1650 employees across the vast site. Recognising a need for specialist assistance, WMBS contacted commercial hot water experts
Adveco to advise on how to meet the criteria in the specification. Upon evaluation and recognising that the building specification would not incorporate any gas connections typically employed in larger commercial structures and secondly, the need to maximise internal space for distribution functions, Adveco proposed a low-carbon, electric-only response based upon its FUSION T packaged electric water heating system. This approach would help contribute towards the building securing its BREEAM certification. Adveco’s FUSION is an award-winning range of low-carbon, all-electric water heating applications
for commercial projects with a wide choice of pre-sized packaged variants. The system comprises an ARDENT electric boiler mounted to a specially configured high-pressure ATSx Stainless Steel cylinder. This provides a compact, highly efficient, low-carbon electric water heater that can be then combined with Adveco’s FPi32 Air Source Heat Pump (ASHP) and dedicated controls and metering for further carbon reduction and operational cost savings. This FUSION T variant can cut emissions by up to 56% compared to equivalent gas-fired alternatives. For new buildings, such as The Stowmarket Distribution Centre, which must now meet regulatory
changes preventing new gas connections, FUSION electric water heaters provided a clear response that was cost-effective, more sustainable and could meet the large-scale daily demands for hot water. Adveco supplied 12 kW ASHP variants of FUSION packaged with 500L ATST twin-coil cylinders and ARDENT Premium 24kW Electric Boilers, with all necessary controls. The ASHPs feed into the lower coil of the ATST cylinder, supplying low-carbon system preheat. The electric boiler, plumbed into the upper coil, supplies necessary top-up heat to achieve safe working temperatures for the commercial application and meet peak demands as and when required. The purpose-designed controls smartly manage the balance between the two heat sources to maximise efficiency and reduce consumption of electricity, reducing associated carbon emissions and controlling operational costs. There is also a highly significant level of redundancy introduced by having a balanced secondary heat source. This reduces strain on all system elements, cutting wear and extending the operation life of the system and reducing maintenance demands. WMBS were extremely “impressed and satisfied” with the FUSION application, swift progression of
the service and ultimate outcome, which contributed to the building securing an ‘Excellent’ BREEAM certification. The hot water system is now “running well and efficiently on-site” with notably lower carbon emissions, which will continue to decrease over the life of the building as the electricity grid undergoes further decarbonisation.
