Collingwood Lighting has introduced strip LED products that can be quickly installed

designed as a direct replacement for tungsten halogen dichroic downlights. As well as offering a 70 per cent energy saving, it also provides a long life of 50,000 hours, which dramatically reduces maintenance costs by eliminating the need for regular lamp changes. LEDs are also being introduced into emergency lighting
systems. Hochiki Europe’s emergency lighting system is an intelligent low voltage system that uses LED technology to provide a unique, highly cost effective and energy effi cient solution, which is ideal for those looking to reduce expenditure within their buildings and keep operating costs to a minimum.
Performance criteria Energy performance and management is being tackled head on, and Part L of the Building Regulations is in place to implement the European Energy Performance of Buildings Directive. The EU Directive on the Energy Performance of Buildings (EPBD) contains a range of provisions aimed at improving the energy performance of residential and non- residential buildings, taking into account the building type, climate and cost effectiveness. Manufacturers are also taking the issue seriously. Thorn

Lighting’s Kelly Herrick, comments: ‘Energy management is something that needs to be looked at in its entirety and there are positive simple things you can do to make a difference.’ Lee Dryden, Osram’s communications manager, agrees
and says: ‘Market infl uences demand an intelligent approach to product design and use, and we are constantly working to make our production processes more eco-friendly. We consider the entire lifecycle of our products, from environmentally friendly product design to safe disposal at the end of their life.’ Products which specifically address this issue are
Luminaires from Riegens Lighting have been installed at the newly constructed Warwick Clinical Trials Unit (WCTU), part of Warwickshire University. Riegens’ Planus fi ttings were specifi ed by Couch, Perry & Wilkes and form part of a totally fl exible, energy saving lighting scheme. The luminaires were specifi cally devised with schools, colleges and universities in
mind. The modern aluminium profi le provides uniform lighting whilst the RT5 optic technology, along with the choice of excellent indirect or direct illumination, results in a high quality fi tting with excellent light output. The Planus College suspended system chosen at WCTU incorporates 2x28w T5 lamps and has been utilised throughout the offi ces, classrooms and any areas where a higher ceiling is in place or where solid soffi ts exist. Neil Foster of Couch Perry & Wilkes, comments: ‘The luminaires were connected through a BUS control system, whereby all lighting is addressed and connected via a modular system to allow for future space planning fl exibility. As this project is a very high thermally performing building, daylight factors are at the high end of the BS 8206, LG10 recommendations and we installed microwave sensors and absence detection with daylight linking. This allowed for the lights to adjust up or dim down, depending on the natural sunlight available. Estimated savings for the lighting system have been calculated at around 40-60 per cent.’
now available. For instance, Tridonic’s basicDIM RCL is a networked lighting management system for control in single rooms that can achieve energy savings of up to 80 per cent, while Venture Lighting’s Ventronic Global electronic dimming ballast combines maximum energy savings with total system control, using DALI digital dimming, simple switch dimming or 1-10V variable dimming. The ballast has low energy consumption and facilitates a 70 per cent total energy cost saving.
Command and control When it comes to energy wastage, it only takes a drive around any commercial district to spot the main offenders – the offi ces and industrial units left with lights blazing, either due to an oversight by an employee, or as a ‘security measure’. This type of activity has led to the suggestion that making
lighting control compulsory is the only way to achieve immediate and signifi cant cuts in energy consumption. John Forsyth, general manager of Ex-Or, is an advocate
of this measure. He comments: ‘A minimum of 30 per cent of the energy consumption accounted for by lighting in industrial and commercial buildings could be saved using existing control technology that automatically turns off the lights when space is unoccupied. Automatic lighting control
using proven technology has an immediate effect on CO2 emission reduction.’
