For the relighting of the Dom Tower in Utrecht, Speirs Major Light Architecture reused 70 per cent of the luminaires which it originally specified back in 2013.
This led to design challenges with optical design and light distribution. Outside of circularity, it was the practice’s first project, where it got to ‘redo’ one of its original designs.
At Circular Lighting Live 2025 this month, Benz Roos, associate partner at Speirs Major Light Architecture, shares his learnings and insights from the project.
He’s one of 35 expert speakers who’ll share their experience and actionable insights into sustainable lighting.
Organised by environmental compliance authority Recolight, this one-day conference and exhibition on Thursday 25 September at the Minster Building in London will put you ahead of the biggest trend in the lighting sector: sustainability.
There’ll be updates on key environmental metrics, standards and legislation, including the new version of TM66, the latest Life Cycle Assessment tools, the UK Net Zero Carbon Buildings Standard and EU and UK environmental legislation.
Adding to the mix is a series of inspirational ‘Just One Thing’ micro talks, the presentation ceremony of the prestigious Build Back Better Awards and debates on key issues affecting the lighting community.
Standby too for the unveiling of radical new initiatives and business models to tackle some of big environmental challenges facing the industry.
Other speakers include architect Hamish Angus McAndrew, Paul Beale of 18 Degrees and Society of Light and Lighting president Kristina Allison.
A ‘moon shot’ debate will explore ambitious ways to accelerate change in the sector.
You’ll be able to choose from eight specially curated sessions to get the most out of the day.
Sessions include climate-driven lighting design, the regulatory roadmap, smart luminaire remanufacturing, managing metrics such as environmental product declarations and life cycle assessments, Cat A and commercial office lighting, innovations in circular lighting, the logistics of circularity such as take back schemes and fitting reuse and finally, inspiring and pioneering projects where sustainability is paramount.
Free to specifiers, Circular Lighting Live 2025 will feature leading experts, specifiers and policy makers who will share their insights into forthcoming standards and legislation, emerging technologies and new business models.
Big brands backing the event include Signify, Sylvania Group, Glamox, KKDC, Prime Light | Group, Prolojik Limited, Thorlux Lighting, Trojan Lighting Solutions Limited, NVC Lighting UK, Mymesh by Chess UK, SMART SYSTEMS UK LIMITED and ALBIS Distribution.
