- Back-office lighting was often left on when no-one was working in the office and could be fitted with motion sensors to prevent lights being left on inadvertently.
- Refrigerated cabinets can be made more energy efficient by installing LED lights. Using a better air conditioning system can also reduce both cost and CO2 emissions.
- Water wastage could be improved by fitting duel flush cisterns in forecourt bathrooms along with watersaving taps.
Shell ESSP (Energy Saving Site Programme) Environmental Project
In 2009, Shell Oil and Coteba (now Artelia International) embarked on a study of how they could make a positive impact on the environment and make a large saving on their energy bills. The study identified the following:-
One of the biggest energy users on a forecourt is the canopy lights, which are illuminated whether or not the pumps are in use. Installing motion sensors and the latest low-energy LED technology could save hundreds of pounds a month on lighting. Many canopies also had more light that is necessary to achieve the lux levels required.
Perimeter lights were also high wattage and using more power than was necessary with modern LED options.
Many forecourt shops were over-lit and don’t make enough use of natural sunlight. Installing light-sensitive switches ensures that lighting costs are kept to a minimum during daylight hours.
Sun tubes installed in the shop roof could provide further natural light to the shop.
Three sites were identified by the Shell team and Xmo Strata were asked to implement of the solutions above onto three UK sites for evaluation.
As part of the preparation, the Xmo team had to mobilise our IEE 17th Edition and Comp’Ex 7/8 accredited electricians and accredit plumbers and a specialist contractor to install the sun tubes under our close personal supervision.
As always with pioneering technology, some of the initiatives were more successful than others and we worked with Coteba and Shell to define an agreed scope of works that was then rolled out to all company owned sites by four specialist electrical contractors, including ourselves.
The savings achieved equated to more than 25% of the estate’s energy bills and was deemed a huge success by all involved.
