Sainsbury's has been considering LED technology for about seven years, first for their refrigerator lighting and later on for feature lighting and car parks. Overtime as the LED technology has developed, the supermarket giant has been considering it for more and more applications.
Last year was a huge advancement of this. Sainsbury's opened its first all LED store in a brand new hypermarket in Leek, Staffordshire. This store consumes about 60% less energy for lighting than comparable stores thanks to the GE 'Blade' fitting, Nonetheless, this is still only one store.
However as of this year, Sainsbury's has made LED lighting the norm and the store in Leek is no longer going to be an exception.
Paul Crewe, Sainsbury's sustainability boss says the energy-efficient lighting is 'one of the most important technologies that we have introduced over the last three years.' All the major supermarkets have been dabbling with LED lighting but the scale of Sainsbury's decision and the sheer amount of attention that they are paying to lighting, makes it a cut above the rest.
Simon Waldron, who joined Sainsbury’s last year as electrical engineering manager, says: ‘My role is to make it 100 per cent LED. But the real challenge is to go LED while maintaining look and feel. Customers are used to walking into a Sainsbury’s store and recognising the brand, and a change in lighting is a big visual element that could impact that.’
Sainsbury's has already built five new stores that are using 100% LED lighting, and replaced traditional lighting in over 100 more. By the end of the year a total of 100,000 LED fittings will have been installed across the Sainsbury’s chain, reducing electrical load by 56 per cent (so far). The new lights are expected to pay for themselves in less than five years.
As a result of the project, Sainsbury’s has made its way on to the Lux Awards shortlist in three categories: retail lighting, recycling, and client of the year.
The company’s lighting team has picked LED equipment from a range of manufacturers to come up with systems for new stores, old stores, big stores, little stores and everything in between. The project covers not just sales floors but also cafes, car parks, petrol stations, offices, back-of-house storage areas and distribution centres.
And to make sure each solution was exactly right for its needs, Sainsbury’s has in many cases developed products in tandem with its lighting suppliers, or requested custom versions of existing products. Dextra supplied a bespoke flat panel, GE developed its original 'Blade' product specifically for Sainsburys in addition to a semi-recessed version.In addition to this, JCC supplied its SkyTile LED panel in a previously unavailable colour temperature. ‘We don’t just take the first product we look at in a catalogue,’ says Waldron, ‘we work with manufacturers to come up with the ideal solution for each area in the estate. Generally we don’t take no for an answer. That’s not being arrogant, but we can always push manufacturers to come up with non-standard solutions that work for us.’
Sainsbury's massive LED lighting upgrade is part of a £1 billion energy-saving project known as Project Graphite – a reference to the carbon emissions that it aims to prevent.
The supermarket industry is more than competitive ever due to the rapid rise of cheaper stores such as Aldi and Lidl. Sainsbury's is hoping that a more sustainable approach and all the benefits that are attached to it. The team have calculated the total cost of owning the LED fittings for their whole lifetime, not just how many years it will take for the lamps to have paid for themselves.
Sainsbury’s aim is to achieve a 30 per cent reduction in carbon emissions by 2020, compared with a 2005 baseline. And because it’s building more supermarkets at the same time, the reductions at each site will have to be significantly higher than that.
The new Sainsbury’s that opened in the centre of Wolverhampton in July is a prime example of what’s being done. The £60 million, 6,700m2 store contains LED luminaires from Dextra, GE, Holophane, JCC, Nualight, Philips, Thorlux and Zumtobel (as well as plentiful daylight through the skylights). It uses about 60% less energy for lighting than a comparable store with traditional lighting.
Its a long while since LED light fittings were recognisable by the grid of glary blueish dots. When choosing manufacturers for this project, Sainsbury’s insisted on four key elements, the first of which was that there be no compromise on the current look and feel of the fittings. The other things suppliers had to offer were energy efficiency, no component replacements for 10 years, and proper recycling of old luminaires.
One area where Sainsbury’s has been particularly clever is the attention is warranties, working with each manufacturer to get the correct warranty to make sure that minimal maintenance would be required for the life of the fittings. Sainsbury’s writes its own warranties with manufacturers, usually asking for five-years’, covering both labour and parts.
Sainsbury's worked with the recycling scheme Recolight, which our sister company, Lightsave Fuller Read, also works with. By the end of this year Sainsbury's will have recycled over 220 tonnes of old lamps and louvres.Whilst recycling their old lamps they are also refurbishing over 60,000 luminaire carcasses that would have otherwise been sent to the scrap yard.
