01
Entopia Building, Cambridge.
Some 350 luminaires removed from a London office Cat A fit-out have been reused in this exemplar sustainable building for Cambridge University. The original supplier of the lights agreed to re-test and re-warrant the lights, and new endplates for the fittings were 3D printed so they could be installed on the exposed ceiling. This process was reliant on insurance approval and the client’s willingness to engage in the reuse process. Energy consumption post-refurbishment is expected to be less than 16 per cent of the pre-refurbishment level.
02
Timber Square,
London.
Landsec’s ambition for this hybrid timber development on Bankside is to create a landmark zero carbon scheme, one of the biggest in the capital. Every element was reimagined from an environmental perspective. So it was with the lighting: it was decided that instead of completing a full lighting fit-out to all 26 floors, just two floors would suffice from a letting perspective. The decision saved over 9,000 luminaires from being installed along with all their associated wiring. The architects on the project are Bennetts Associates and the consulting engineers are Hoare Lea.
03
Botanic Square,
Cambridge.
Botanic Square is a 500,000 square feet project that is slated to become the most sustainable workspace in Cambridge. The design has been updated to reduce the amount of carbon used in construction and to improve the operational carbon performance. As part of this, a flexible track and trunking lighting installation will be provided on all floors to provide flexibility in the move from a Cat A fit-out to Cat-B. One floor will be fit out fully, with the rest of the floors illuminated to background light levels of 100 lux.
04
Devonshire Square,
London.
Squire & Partners is sensitively refurbishing and extending Building 7 at Devonshire Square in City of London to create a vibrant office-led campus on the Liverpool Street site. It is targeting a Breeam Outstanding rating and a five-star NABERS score. Office floors are designed as open plan, Cat A standard workspace, but the team has decided to fit out just one floor initially rather than the entire building. Early-stage calculations estimate that the move will achieve carbon reductions of about 600 kgCO2/m2. The sustainability consultant on the project is Hoare Lea.
05
Building Crafts College, London.
Some 300 linear metres of luminaires were removed from a Cat A fit-out on the South Bank and reused in this construction training college. The salvaged fittings underwent inspection and maintenance at the factory of lighting manufacturer Silent Design. Despite being just six months old and unused, all fittings had their batteries replaced, underwent comprehensive re-testing of wiring and components, and were customised into 1500mm units with custom end-caps. Silent Design has even given the client a five-year warranty. The project was undertaken by Evolve Services Group.
06
Skanska,
London.
Construction giant Skanska reused and upgraded luminaires at its London headquarters rather than replacing them. The company took advantage of a take back scheme from lighting maker Trilux to re-purpose the original luminaires, re-using all salvageable material and upgrading to the latest LEDs and drivers. In addition, areas originally designed for a cool colour temperature of 6000K for a call centre were modified to a warmer 4000K using specialist filters, avoiding the waste of perfectly functioning luminaires well before the end of their useful life.
07
Fenchurch Street,
London.
A upgrade project in the City of London using remanufactured luminaires cut energy use by 55 per cent. Revitalite 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 use of quality components and careful installation allowed Revitalite to provide a five-year warranty on all the light fittings.
08
51 Lime Street,
London.
A LEADING insurance company has reused 1,400 luminaires in a refurbishment at its City of London headquarters. Fifty-one Lime Street, also known as the Willis Building, is 30 storeys tall. The lighting refurbishment saw 1,400 luminaires upgraded and reused, leading to a 39 per cent energy reduction. Kent-based FUTURE Designs, the original supplier of the lighting, developed a new gear-tray design which used the latest optics to give the appearance of a fluorescent but with the benefit of LED. Photometrically testing the prototypes ensured that the light distribution was maintained.
09
Arup,
Manchester.
Arup teamed up with luminaire remanufacturing business The Regen Initiative to reuse the lights in a refurbishment of its Manchester offices. The fluorescent gear and lamps were replaced with LED modules and drivers, and some additional luminaires were repurposed from a Cat A fit-out office in Leeds, which would otherwise been disposed of. The Regen Initiative ensured that the optical performance of the retrofit solution would be maintained. The project’s carbon consumption was reduced by over 47 per cent and the energy use was cut by 72 per cent.
10
10 Upper Bank Street, London.
International aw firm Clifford Chance saved 56 tonnes of steel by reusing rather than replacing 22,000 luminaires during a lighting upgrade at its 151-metre 32-storey London docklands headquarters. The company is the latest in a line of major lighting industry clients demanding low carbon fluorescent-to-LED upgrades that minimise waste and recycling. The switch – by Kent-based FUTURE Designs – resulted in an immediate energy saving of 51 per cent, with a comparable light output. This is a saving of over 1,000 tonnes of carbon over a five-year period.
11
The light panel designed for reuse.
Scottish manufacturer EGG Lighting has unveiled a ceiling panel light that’s been designed from the outset for remanufacturing. At the end of its life, EGG says that the 600mm x 600mm fitting can be upgraded to like-new condition. The optics, LED module and control gear are designed to be easily interchangeable. The company says it has used its experience in remanufacturing to design the product, which is known as the Designed for Remanufacture, or DFR, panel. The DFR has a Cibse TM66 circularity rating of 2.6, putting it in the ‘excellent’ band.
12
Mobile workshop
Scottish firm Stoane Lighting has created a mobile workshop in which technicians can upgrade, test and re-warranty office and other lights. The ReNew division was set up to to avoid the disposal of luminaires when there is likely an opportunity to refurbish. The firm upgrade lights with the latest LED, driver and/or optical technology while retaining the product’s robust mechanics. Once the ReNew service is complete, the company offers a new five-year warranty and commitment to a further 20 year duty of care. Any unwanted parts will be recycled.
