Waitrose’s ‘invisible door’ could save £1.5bn

Waitrose & Partners will introduce an ‘invisible door’ that has the potential to save British retailers a combined £1.5bn per year by reducing their energy bills.

Wirth Research’s AirDoor provides an archway that sits outside the store, located around the frame of the existing entrance and prevents warm air being lost from the store during colder temperatures and cold air being lost during warmer temperatures as customers enter and leave, meaning doors are often left open for long periods. It will perform particularly well in instances of extreme temperature or pressure differences as well as strong winds.

The concept is scheduled to launch at the supermarket’s Berkhamsted store later this year and, if successful, there are plans to roll the AirDoor out to more Waitrose shops.

The AirDoor was co-funded by Innovate UK – the Government scheme that rewards innovation with global potential. Innovate UK is part of UK Research and Innovation, set up to drive productivity and economic growth by supporting businesses to develop and realise the potential of new ideas.
