Open-fronted fridges are the largest consumer of power in stores and after extensive laboratory and store trials, M&S has seen proven energy savings from Aerofoils, with the added benefit of a more comfortable temperature for customers and colleagues. 

Results from existing client adoption of Aerofoils have proven that customers can save up to 30 percent on refrigeration energy costs through this straightforward, cost-effective and retrofittable solution.

Aerofoil, from Aerofoil Energy, is influenced by Formula One aerodynamics from Williams Advanced Engineering – part of the Williams Group that also includes the Formula One team – and is similar in appearance to the rear wing of a Formula One car. It uses aerodynamics to guide cold air down the fridge more efficiently, meaning substantially less cold air is lost from the chiller unit, resulting in lower energy use, fewer carbon emissions and warmer aisles in stores.

Paul McAndrew, chief executive of Aerofoil Energy, said: “Aerofoil Energy is delighted to be working with such an internationally iconic brand in food retail as M&S. This was a very interesting development project for us because M&S has its own bespoke refrigeration cabinets; the whole design process required close collaboration from the Aerofoil team with M&S to arrive at the most favourable and energy-efficient solution. As a result of this relationship, M&S will deploy three new technologies, taken from our Vortex project, that together have enhanced the performance and aesthetics of Aerofoils.”

Ian Moore, head of store development at Marks & Spencer, said: “We’re excited to be collaborating with Aerofoil Energy to reduce the energy consumption and environmental footprint of our stores. This technology will also help us offer a better shopping experience for customers by improving the temperature in our aisles.”
