Harvesting savings from the latest LED technology
With many businesses making the switch to LED lighting – and enjoying the benefits of significantly lower energy costs – we look at how you can make the most of your investment in LED with the latest control technology.
Facilities managers are now aware of the main benefits of LED units over conventional lighting. LEDs typically use up to 60% less energy than their conventional equivalents, and the associated cost and carbon savings have encouraged many businesses to adopt this technology. However, there are a number of additional technologies that can provide enhanced benefits compared to simply replacing with LEDs on a like-for-like basis. While these solutions may require greater up-front investment than simple one-for-one replacement, payback will be quicker and the ongoing savings even more impressive.
Capture daylight savings
Daylight harvesting sensors detect light levels and automatically adjust the LED’s output according to the ambient lighting available, consistently providing the lighting you need. For instance, if sunshine is streaming into an area lit by LEDs with daylight harvesting controls, the LED units will be automatically dimmed. At times when natural light levels are low, the LEDs will produce more light – providing comfort, safety and security for building users. Adding daylight harvesting sensors to your lighting solution can achieve further savings of up to 15% on top of basic LED replacement. Lighting activation levels can be adapted to suit changing requirements, and the life of the LEDs is extended due to lower average usage.
Introduce intelligent lighting Do you need non-stop lighting? There’s no need to rely on user education to switch off lights when they’re not needed. With motion sensor technology, you can be sure that you’re not spending money continuously lighting areas that are not in constant use.
Modern LED lighting can be gradually dimmed when it is switched on or off to reduce the contrast between light and dark, creating a more pleasant environment for building users. Lighting can also be maintained at a constant low level when full lighting is not required, helping to maintain safety and security. Lighting can also be linked into your Building Management System, enabling the use of pre-set timings and remote control.
Boosting savings further
The additional benefits of intelligent LED lighting solutions combine to maximise the ongoing savings of your investment. By providing lighting only when it is needed – and only to the level that is required – your air conditioning systems will use less energy to offset heat produced by lighting.

Perforated feature panels dazzle in the dark
The stunning new £60 million first direct Arena in the northern quarter of Leeds operated by SMG Europe, features Sotech’s back-lit perforated panels which light up the Leeds skyline with a kaleidoscope of ever-changing colours, producing a dazzling honeycombed external façade on what is believed to be the first ‘fan shaped’ arena in the UK.
The giant dome of the arena, rising to 35m in height, contains a skin of aluminium shingles finished in graduated shades of mint green and brown. The landmark 13,000 capacity entertainment focused arena designed by architects Populous and constructed by BAM for client and developer Leeds Council, boasts a unique honeycombed external façade based on a series of geometric layers punctured

with hexagonal tinted glass to the main entrance area. The varying shapes of the glazing, reminiscent of the cellular composition of a giant insect’s eye, are further emphasised by Sotech’s hexagonal perforated aluminium feature panels fixed back to a lightbox and adjoining the glazing. Working closely with leading building envelope specialist Lakesmere to achieve an integrated solution for over 400 square metres of aluminium feature panels, Sotech achieved an economical method of producing the 9mm perforations with the use of a sophisticated cluster tool enabling a number of holes to be punched simultaneously across a wide and complex variation of shapes and sizes.
The perforated feature panels subtly echo the cellular nature of the aluminium shingles during the day, but at night the seemingly randomly patterned perforations in the Sotech aluminium feature panels give way to an illuminated tracery, providing an almost psychedelic lighting experience featuring a palette of mesmerising, vivid colours which light up the Leeds skyline.
