[ Spotlight: Lighting] Ex-Or claims that legislation to manage the use of this
technology could achieve savings of £1.5bn and achieve cuts in CO2
emissions equivalent to 1.8 per cent of the
UK’s contribution to the European Union’s pledge to cut greenhouse gas emissions by 20 per cent by 2020.
Standard bearer The day when lighting controls are the rule rather than the exception is set to move a step closer later this year with the publication of BS EN 12464-1: 2011, the revised European standard for lighting indoor workplaces. The purpose of this standard will be to address the design
and development of lighting schemes around a specific task or activity. BS EN 12464-1: 2011 will encourage designers to consider all available forms of lighting, including daylight, and also look at how wall and ceiling colours can be used to increase a room’s brightness. It will also provide guidelines about the use of lighting controls and recommend ways to illuminate rooms only when they are in use.
A bright future The lighting industry is clearly undergoing radical change and is set to become much more diverse in terms of suppliers in the next few years. The demands on ever more efficient light sources and assurances of achievement of performance claims, as well as increasing demands to innovate in areas such as LEDs, will ensure that companies with the resources and the know-how will remain at the forefront in providing ever more appropriate, controllable and sustainable solutions.
What’s in store?
M&S store in Ecclesall Road, Sheffield
Marks & Spencer (M&S) has unveiled its new lighting approach with the opening of its store in Ecclesall Road, Sheffield, where Philips LEDs have been installed throughout, in conjunction with a Philips Dynalite lighting management control system. This makes it one of the first UK stores to be 100-per-cent lit with LED technology. By applying LEDs across its car park
area, back of house and shop floor, M&S can now enjoy typical energy savings of 25-30 per cent on its lighting electricity usage, in comparison with other stores using conventional light sources. These savings can be increased still further as a result of the new lighting control system now in place. Specific use has been made of ‘daylight harvesting’ by controlling the light fittings so that M&S can take advantage of the free natural daylight that pours in through the windows, automatically dimming the luminaires within the area so that a constant level of light is maintained in the working space.
As well as the immediate energy savings, the company will also benefit from a reduction in maintenance costs, as the long life of the LED sources means that no re- lamping should be required through the life of the store. Richard Gillies, director of sustainable business and CSR at M&S, explains: ‘We’ve
made some bold commitments as part of our target to become the world’s most sustainable major retailer by 2015, and substantially reducing energy use is one of them. LED lighting is an important part of our reduction strategy and provides bright, consistent light levels which really complement our products.
