Airedale saves millions for Iceland stores

Food retailer Iceland has reduced energy costs by £4.8 million following the installation of Airedale’s ACIS control system in all its 800+ stores, an average of £6000 per store, as part of a major upgrade programme. The move followed the success of installations in 50 stores. In stores where the control system was installed but no changes made to plant, Iceland could compare and evidence energy draw before and after installation. Energy costs have been reduced by 10%, with an expected payback on the investment within two years. The new system provides tighter and more intelligent levels of control, coupled with free cooling and part-load efficiencies during off-peak and non-trading hours.

Iceland required a standardised control system that could be integrated into all stores for new and existing cooling plant from Airedale and for retrofitting to other manufacturers’ equipment. The system enables Iceland to intelligently manage HVACR and other building services across multiple sites from a single central system.

Key requirements were for the controller to be pre-programmable for a standard store and configurable on site, with selectable install parameters, saving significant installation costs.

Graham Ireland, project manager with Iceland, explains that the ACIS system is flexible and accommodates individual store criteria by changes to the software.
