Luceco has provided a cost eecve, energy saving LED lighng soluon for three major buildings on the Parkgate Road Campus at the University of Chester.


LED LIGHTING REFURB FOR CHESTER UNIVERSITY Carbon footprint and energy consumpon reduced


services and facilities are located here as well as sports facilities, science and language laboratories. The University of Chester was founded by pioneers including William Gladstone and the Earl of Derby. It is one of the oldest English higher education establishments, pre-dating all but Oxford, Cambridge, London and Durham. The lighting design brief was to reduce the energy consumption of three major buildings – the Best Building, Westminster Building and Chritchley Building – with a payback of within five years. The lighting refurbishment programme has been funded by the Salix scheme. Established in 2004, Salix Finance Ltd delivers 100% interest-free capital to the public sector to improve their energy efficiency and reduce their carbon emissions with loans for energy efficiency projects.

An impressive selection of fittings has been employed including more than 750 LuxPanel luminaires installed into many areas including seminar rooms and lecture theatres, offices, and laboratories.


Quick and easy to install with no


he University of Chester has six campuses, with the 32-acre Parkgate Road Campus featuring a mix of buildings dating back to 1839. Many of the University's central


maintenance requirements and no visible frame when installed in the ceiling grid, high efficiency LuxPanels have the additional benefit of 13% extra visible light when compared with other LED panel luminaires. Supplied with remote 'plug and play' drivers, available in standard fixed output, dimmable and emergency options, high efficiency LuxPanels offer a market leading efficacy of 152 Lm/cW. Movement around the university requires a good uniformity of light and careful luminaire choice is important when lighting confined spaces such as corridors. The use of LED flat panels prevent intrusion from the luminaire into what is often a small space enduring large amounts of traffic.


More than 200 Circular LuxPanels were installed, mainly in circulation areas and rest rooms. Featuring slim framed panels, Circular LuxPanels offer excellent luminous uniformity and can be supplied as standard, with emergency packs or with dimmable remote drivers in 240, 180, 150 and 120mm sizes, further demonstrating the diversity of the LuxPanel range.


Other luminaires installed in transit areas included the Atlas Bulkhead, providing an alternative to traditional 28 and 38 watt 2D compact fluorescent fittings. Selected Atlas luminaires installed were fitted with an integral microwave sensor to further reduce energy consumption.


With the corridor function selected, the sensor adjusts the light level to 10% of the normal level when the space is unoccupied.


Retroflt opon


Platinum LED Downlights were also installed in breakout areas and landings offering running cost savings of up to 80%. Designed to retrofit ceiling cut outs of common compact fluorescent downlights, the Platinum features easy fit positive locating swing out tabs and interchangeable bezel options and is ideal for use with sensors and lighting controls.


Further circulation areas, corridors and offices were lit with the Academy luminaire. Academy is as an ideal replacement for linear fluorescent fittings in classrooms and circulation areas and offers an impressive 50,000 hours of maintenance free operation along with the LuxPanel, Platinum and Atlas fittings.


As with the Atlas, some of the 20 BUILDING SERVICES & ENVIRONMENTAL ENGINEER MAY 2018


Academy luminaires were also fitted with an integral microwave sensor to adjust the light level to 10% of the normal level when the corridors were not being used, to further improve energy efficiency.


Titan High Bays, complete with prismatic diffusers, were installed in atrium areas also offering high efficacy and instant light unlike traditional HID fittings. Large spaces within education environments often serve many functions such as assembly areas, dining halls and interior sports facilities. LED lighting technology delivers significant cost savings compared to traditional light sources and with no maintenance required throughout the lifetime of the luminaires, cost and inconvenience of lamp replacement, often requiring expensive equipment to gain access, can avoided.


Sport England guidelines


Replacement lighting for the Sports Hall required compliance with Sport England guidelines and LuxBay luminaires from Luceco were selected. LED LuxBay is environmentally friendly with no warm up time to produce 100% light output. Variants include 100, 150 and 200 watts, all with either a wide or narrow clear lens, offering over 50,000 hours of operational life. Options include integrated presence and daylight sensors for use with fixed output or DALI dimmable control as well as integral emergency variants.


The Best Building, Westminster Building, and Chritchley Building now demonstrate a substantial reduction in energy consumption and carbon footprint by over 66% as a result of the LED lighting refurbishment


programme. Moreover, maintenance on lighting provision has been substantially reduced due to re-lamping of luminaries being completely eliminated.


Due to the success of these first three buildings, further refurbishments have followed including buildings at the Riverside Campus housing the Faculty of Health and Social Care. Other sites include the Warrington Campus, originally a camp for Canadian officers in WW2, now the home of the North- West Media Centre and the training ground for the rugby league team The Warrington Wolves.
