Ex-Or brings greater efficiency to lighting
By being controlled effectively by an Ex-Or lighting-management system, the new lighting system in this Birmingham office will save £3000 a year in electricity costs.
By delivering light only when needed and in the required quantities, the refurbished lighting system in the Birmingham office of Royal & SunAlliance is expected to reduce electricity bills by £3000 a year for this 3-floor office complex in Colmore Row. The Ex-Or MLS digital lighting-management system ensures that lights are on only when needed and controls light output according to ambient light. It also allows the company more flexibility as a growing number of its 700 employees work outside the time frame of 9 a.m. to 5 p.m. Detectors sense the presence of occupants and measure levels of ambient light. The detectors communicate with one another to provide the correct level of light for occupants in designated work zones throughout open-plan areas and ensure that lights in key circulation areas and corridor routes are kept on. Roger Rigby, senior electrical engineer with consultants Cundall, explains, ‘The main driver for Royal & SunAlliance was efficient delivery of lighting so that the system would be as environmentally friendly as possible. The company has an energy team which actively monitors energy use throughout the complex and estimates it is saving £3000 a year off the lighting energy bill as a direct result of the new lighting system.’ He said that the former lighting system was old fashioned and inappropriate, particularly as some staff need to work in the early mornings and late evenings. ‘They needed a system that would automatically deliver correct levels of light whenever required. Previously, the landlord had to be contacted whenever lights were needed outside the core working hours.’ The lighting is from Fagerhult, for which Ex-Or is a preferred supplier.
