“Lighting is responsible for a whopping 20 per cent of all electricity consumed ”

building management system. Simply applying the same solution to lighting can achieve additional savings in the range of 30-40 per cent, whilst creating environments that respond to your exact needs. Proper control saves money, reduces carbon footprints and (done properly) will have no negative impact on business operation whatsoever. As we look ahead to daunting energy challenges, it’s clear that delivering significant energy and carbon savings whilst continuing to grow, innovate and perform will be a key challenge for all businesses. Lighting is an obvious and rewarding area to start to make changes, whilst today’s advanced technology offers the potential to significantly improve built environments. Control is the key to meeting these objectives. Specified alone, LED solutions are impressive.

Coupled with intelligent control systems they represent the future of highly efficient, highly functional lighting design.

Solution Open Technology has undertaken a project at Europe’s busiest train station, which illustrates the benefits of intelligent lighting solutions. In fact, Clapham Junction is the latest in a series of projects that has seen Network Rail and South West Trains work in partnership with Open Technology to introduce intelligent lighting controls across its infrastructure. Following an initial installation at Woking Station in 2010, LiGO has now been introduced at 25 stations and train maintenance depots across the Wessex Route. Installing lighting control is one part of the South West Trains, Network Rail Alliance’s climate change and

energy reduction strategy that is estimated to achieve total annual savings of seven million to 12 million pounds and a payback period of approximately six years. Delivery of a safe environment is of paramount importance in the transport sector, and the challenge is to achieve maximum savings for operators, alongside comfort and safety for staff and passengers. Open Technology’s LiGO control system is able to provide the exact light levels required across the station, matching lighting use to train timetable, passenger presence, daylight levels and other varying uses. The system is able to ensure maximum savings throughout the year as well as reduce light pollution in the surrounding area. For the first time, Clapham Junction station will be able to automatically dim the lights down to a minimum value when the station is not in operation or switch the lights off when the station is completely closed. On average, this would amount to savings of 35 per cent of usual lighting use. “Intelligent lighting has enabled us to save, on average, 20 per cent at each location,” explains Amy Dickinson, environment manager Southwest Trains, Network Rail Alliance. “An automatic control keeps it simple for us. It enables us to save as much energy as possible, by dimming down and turning off automatically when not in use. It also tracks usage, which helps us to spot any areas for improvement and understand how our buildings are being used.” m
