Remanufactured luminaires cut energy by 55% in City office

Synergy Creativ

An upgrade project in the City of London using remanufactured luminaires has cut energy use by 55 per cent.

Revitalite, sister firm to Hertfordshire-based commercial lighting firm Synergy Creativ, replaced fluorescent lamps and gear with LED modules at 71 Fenchurch Street, a building owned by Savills.

The primary challenge encountered by Revitalite team was the building’s tapered design. As a result, each light fitting needed to be a different length to fit accurately within the existing chilled beam housing. The irregular dimensions posed a significant obstacle in designing, remanufacturing, and installing the retrofitted fixtures, potentially impacting the overall energy efficiency and aesthetics of the building.

The team conducted a comprehensive site visit to examine the existing chilled beam housing and understand its intricacies. By physically inspecting the spaces and taking precise measurements, they gained valuable insights into the available spaces and the best ways to integrate the new fittings seamlessly.

After the site visit, Revitalite used the acquired measurements to create detailed drawings. These drawings accounted for the tapering dimensions, ensuring that each light fitting would be tailor-made to fit perfectly into the chilled beam housing. The team collaborated closely with manufacturers to customise the fittings accordingly.

The use of quality components and careful installation allowed Revitalite to provide a five-year warranty on all the light fittings.

The total yearly energy consumption will be cut to 21,000 kWHr from 47,000.

Revitalite also offers a number of additional control options such as DALI dimming, daylight dimming and absence and presence detection.

‘Reconditioned lighting is the future of sustainable lighting solutions,’ says chief operating officer Mike Stay. ‘We’re committed to providing high-quality products that meet the needs of our customers and help to reduce the environmental impact of lighting.’
