Design and install new forecourt lighting scheme to reduce energy consumption and minimise maintenance costs.
MITIE was asked by Total UK to design and install an energy efficient lighting scheme for the Smithdown Road service station, Liverpool. The scheme encompassed all areas of the service station, from canopy lighting to the retail shop, and was designed to trial new technologies with the view to introducing further installations throughout the Total UK estate. An integral element of the contract was to document and report on energy savings, which meant measuring the service station’s energy consumption before and after the refit.
What was Total UK looking for?
Total UK required a lighting scheme that could effectively demonstrate significant energy, carbon and cost savings, without compromising the lighting quality and customer safety. It was important that the new lighting was cost effective and was able to project a very achievable and short-term payback on investment.
How did we help?
MITIE was able to achieve significant savings by replacing old 400 HID canopy lighting with new twin 80 Watt luminaires with optical reflectors to direct maximum light onto the forecourt. The forecourt lighting utilizes dimmable high frequency electronic control gear with the original daylight sensors operating in sequence with a new ‘presence detection system’ that dims by 25% when the forecourt is not in use. LED floodlighting replaced old 250Watt and 80Watt lamps, whilst refitting the retail shop with T8 fluorescent power saver sets reduced energy consumption even further.
To ensure accurate results, a ‘clamp data logger’ was installed to measure the energy consumption of the lighting before and after the installation, whilst light readings were also recorded.
The energy consumption of the service station’s lighting scheme was reduced by 57%, saving over 56 tonnes of CO2 emissions per annum presenting a payback period of just three years. Such significant reductions were achieved through the combined use of the latest energy efficient fluorescent lamps, LED floodlighting and by linking daylight sensors with occupancy detection sensors to dim the forecourts lights when not occupied. The trial has successfully demonstrated that using a combination of compact fluorescent canopy lights and LED flood lights offer significant benefits, including reduced energy consumption, lower maintenance costs and a smaller carbon footprint, while not compromising on lighting levels.
