Case Studies Refurbishment: an opportunity to install lighting management Office building owners and occupiers are increasingly seeing refurbishment as an opportunity to incorporate sophisticated lighting systems and controls. It could be a complete internal refurbishment, or a lighting upgrade where inefficient luminaires are being replaced. Whatever the degree of refurbishment, the incorporation of lighting management delivers three real benefits: significant reduction in energy costs due to the elimination of unnecessary lighting; compliance with legislation; and the creation of a more productive working environment. "Royal & SunAlliance’s annual £3,000 saving" This was demonstrated when a major lighting refurbishment incorporating sophisticated lighting management from Ex-Or was carried out at Royal & SunAlliance's Birmingham office complex. Because the new Fagerhult lighting system only delivers light when needed without any energy wastage, thanks to Ex-Or, Royal & SunAlliance cut its carbon footprint and now benefits from an annual saving of £3,000 on its electricity bill. It allows the company more flexibility as a growing number of its 700 employees work outside the core 9 am to 5 pm time frame. And because the lights are automatically set at optimum levels, Royal & SunAlliance staff are working in a healthier and more productive environment. “Energy cost savings of between £7,000 and £9,000 for SEEDA” Managed lighting systems from Ex-Or put the South East England Development Agency (SEEDA) well along the road to BS EN ISO 14001, the standard for environmental responsibility and sustainability. The Ex-Or MLS Digital Managed Lighting System was installed at SEEDA's five storey HQ building in Guildford to completely eliminate the unnecessary use of office lighting. Not only has this helped them meet their ISO 14001 environmental responsibilities, it has also meant that electricity consumption has been cut by up to 15 per cent - an annual energy cost saving of between £7,000 to £9,000. The existing recessed 2 x 36W LG2 Cat 2 light fittings were replaced by 4 x 14W T5 ALD Lighting Fusion luminaires, and the Ex-Or MLS Digital Managed Lighting System was installed throughout all open plan offices, cellular offices and meeting rooms in the two wings that make up the building. The installation means that the lights no longer blaze endlessly and needlessly outside office hours just because people have forgotten to switch them off. Before and after metering measurements were taken in the first wing to be converted, and they showed an immediate cut in electricity use of 20 per cent. Because each wing has different levels of natural light, a building-wide saving of up to 15 per cent will give SEEDA a payback period of just over two years.” “Automatically delivers light at optimum levels” Managed lighting systems from Ex-Or were installed throughout the West London HQ building of dunnhumby, the high profile international marketing company behind Tesco's Clubcard scheme. All four floors of the office building in Ealing were refurbished to provide higher quality accommodation for dunnhumby's 350 staff. The Ex-Or MLS Digital Managed Lighting System was installed. It automatically ensures that lights remain on only when needed, and automatically delivers light at optimum levels. Doug Good, director of property and procurement with dunnhumby, said that compliance with legislation and the need to cut energy were the two main reasons for choosing the Ex-Or MLS Managed Lighting System. The prestigious 82,000 sq ft eight-storey office building 15 Fetter Lane development in the City of London underwent a complete refurbishment with the interior being gutted and refitted and new external facades created. Consulting engineers Foreman Roberts Ltd specified the Ex-Or MLS Digital Managed Lighting System throughout the building. Straightforward to install, providing automatic energy-saving operation and offering the option to access further levels of functionality as and when they might be required by individual tenants - the Ex-Or installation delivered a cost-effective yet supremely flexible solution to meet the aspirations of this prestigious, multi-occupancy office development.
