The 38-site project was finished on time and within budget, and Spire Healthcare is now able to significantly reduce its energy spend while enjoying excellent levels of illumination in its external car parking areas.

The project began in June 2014 and was completed in two phases – the first comprising 21 of the largest energy consuming sites – and FES replaced 1184 fittings in total. The new LED luminaires have achieved in excess of 73% energy savings, while also providing 25% better light output. Furthermore, they have an enhanced rated life of up to 20 times better than the previous luminaires in some cases.

"Spire Healthcare will save just under £800,000 over a 10-year period," explained Marcus Brodin, commercial director at FES. "This figure includes over £564,000 in energy savings, over £188,000 in maintenance costs and £43,000 in environmental tax savings related to the CRC Energy Efficiency Scheme. With an overall energy usage reduction in excess of 428,000kWh, the effect on the environment will also be significant too, with carbon dioxide (CO2), mono-nitrogen oxide and sulphur dioxide (SO2) emissions all drastically lowered."

The previous infrastructure comprised over 44 different luminaire types, ranging from small 50W bulkhead fittings to large 1000W floodlights, all of various ages and conditions. In order to deliver a degree of uniformity FES installed five core LED replacement luminaires from the Thorlux lighting range – the Corn Lamp, Flood, Wallpack, 1500mm LED Luminaire and Globe.
