Thorn Energy Solutions helps Centre Retail Park slash energy by 89%
Centre Retail Park in Oldham has 245,000 sq. ft. of retail space and car parking facilities, with over 1,100 parking spaces. Occupiers include national retailers and restaurant chains, including Boots, Carphone Warehouse, Next, McDonald’s and Pizza Hut.
With the existing car park lighting scheme comprising 45 column-mounted 400W SON luminaires (with 52W gear losses), the site had a dull orange glow. Despite only 60% of the lighting working, it consumed 82,224 kWh per annum, with frequent lamp failures adding to the high operating costs.
In conjunction with Centre Retail Park agent, Savills, and Stroma, a leading authority in meeting energy reduction targets, an assessment was undertaken to determine a suitable replacement. As well as reducing energy consumption and improving lamp lifetime, a crisper light output was required to create an enhanced shopping experience with a greater sense of security.
LED replaces SON
Thorn Energy Solutions specified the Indra 98W road lighting luminaire with Bi power dimming to reduce energy consumption by 50 per cent during nighttime hours.
With its advanced optical performance, Indra offered the highest lumen output and also met the payback requirement of less than four years. Indra also reduces maintenance costs to practically zero, while still achieving the CIBSE requirement of 20 lux for car parks.
The 45 Indra fittings are mounted onto the existing lighting columns, using double-headed units where twin SON fittings had been previously used. The entire scheme is backed by Thorn’s comprehensive 5-year product guarantee for peace of mind.
