RSG unwrap energy savings

Following the installation of T5 lighting from Riegens, The Retail Supply Group (RSG) is living proof that a simple change to fluorescent lighting can now offer a cost effective alternative to HID luminaires for high bay applications in warehouses. The refurbishment, financed by a Carbon Trust loan, has allowed the company to install the new lighting quickly and efficiently, providing immediate savings in energy and costs.

Within RSG sits Glopac, a well established packaging supplier to major UK retailers, and Greenpac, a fast growing pioneer in environmental solutions across both packaging and textiles. It was clearly appropriate that a company with such strong green product credentials should seek to behave in an environmentally responsible way in all areas of its operations.

The task therefore was to explore all the options for re-lighting the warehouse to provide a new lighting scheme that would comply with the CIBSE guidelines for warehouse lighting, but at the same time reduce energy consumption. Results of investigative work demonstrated that by changing the existing 400W metal halide lamps to Riegens HB-ECO 4 x 54W fluorescent fittings using 4000K colour temperature tubes, significant savings could be achieved.

Part of the Riegens power saving ECO range, the HB fittings are controlled via occupancy and daylight sensors to minimise running costs.

Designed for surface mounting or suspension, HB-ECO provides excellent vertical illuminance thanks to dedicated asymmetric reflectors that provide optimum light distribution. Available with lamp packages designed to suit any installation, HB ECO comes in two or four lamp options, with a choice of 40W, 50W or 80W PLL lamps for large open areas, and all T5 variants for storage areas. Control gear options of HF, 1-10V analogue and DALI dimming or dimming with integral PIR sensor are available with other options including three hour emergency on request.

Following the installation, Liam Knowles, a Director for Greenpac commented: “We are delighted with the significant increase in light levels, coupled with immediate energy savings achieved through this replacement system which is fully in line with and reinforces Greenpac’s philosophy. Riegens were recommended to us by a previous major retail client and we are particularly impressed with the comprehensive savings the system offers through its combination of movement and daylight sensors. By taking advantage of The Carbon Trust government grant, we have identified significant projected energy savings providing an anticipated payback calculation of up to three years maximum.”
