Waitrose & Partners will trial the first “invisible door” at its Berkhamsted store later this year. Developed by Wirth Research, the AirDoor concept places an archway outside of the frame of the existing entrance that prevents conditioned air from being lost when the door is opened or stays open. The solution is inspired by Formula One racing technology to guide air towards appliances to heat or cool appropriately. The AirDoor uses sensors to detect airflow in both directions and counteracts it with self-generated wind to create a barrier that stops heated or cooled air inside the store escaping and outside air flowing in. According to Wirth Research, this negates the need for revolving doors or lobbies.
