The engineering consultancy Sweco UK has upgraded rather than replaced the lights at its Maidenhead office.
Trilux reconditioned the existing fluorescent, which are installed in multi-service chilled beams, replacing the fluorescent lamp with an LED gear tray and the louvres with micro-prismatic diffusers.
The project got the go-ahead after a successful mock-up where Trilux presented a customised trial luminaire that modernised the appearance and performance of the original fittings.
‘By reusing and refurbishing rather than replacing, we not only minimised waste but improved the quality of the office lighting for our team,’ Conor O’Donoghue, operations director at Sweco UK, told the Circular Lighting Report. ‘Trilux supported us every step of the way, ensuring the results met both our operational needs and circular economy objectives.’
The two firms say that the collaboration was underpinned by shared values around climate responsibility, circularity, and the creation of better environments.
Both Sweco and Trilux are committed to the United Nations Sustainable Development Goals and see the transition to a circular economy as key to addressing climate and resource challenges.
This shared ambition shaped the project’s approach—from minimising waste through luminaire refurbishment to enhancing lighting quality and workplace wellbeing.
Trllux says that the refurbishment marks another milestone in its mission to support clients in making the shift towards a circular economy. It also sets a strong precedent for future upgrades within Sweco’s UK office portfolio, proving that sustainable design can sit side-by-side with performance and aesthetics.
