The challenge Airedale solution
Iceland is a leading high street supermarket chain with 800+ stores across the UK selling frozen and • 800+ stores chilled food and groceries. Famous for its pedigree • Energy savings increased by 10% in frozen foods, Iceland worked with Airedale to • Savings of £6,000 per store deliver a standard, optimised, control system which • 2 year payback period could be applied across all stores to maintain store • ACIS™ control system across all stores environments and produce significant energy cost- • ACIS™ building energy management system savings. across 10 stores
Iceland required a standardised control system that could be integrated into all of the retailer’s stores for Previously we had infrastructure in both new cooling plant and retrofit, to offer optimised “ place to incorporate free-cooling, but control, free-cooling and simplified spares availability. our standard range of controllers had The controller had to be pre-programmable for a only fixed capability. Airedale’s controls standard store and configurable on site, with selectable solution allows us to use the same strategy, whilst enabling attainable install parameters. energy savings to be achieved.

Energy costs in our stores have reduced by 10% through tighter, more intelligent levels of control. Based on these results, over the course of a year, across all stores, Iceland’s total building energy costs of £45 million is expected to reduce by £6,000 per store.
