Lower carbon impact at open entrances

AirDoor supports sustainability and net‑zero ambitions by consuming less energy than traditional overdoor heaters and reducing energy loss, heating demand and carbon emissions at the entrance, without compromising comfort, access or performance.

How AirDoor supports sustainability

Consumes less energy than traditional overdoor heaters

Unlike traditional overdoor heaters, AirDoor operates without any heating or cooling element, avoiding the high energy demand associated with continuously generating heat at open entrances. Instead, it uses a smart control strategy and variable‑speed fans to respond only when required, consuming the minimum energy needed to manage entrance infiltration.

By combining sensor‑controlled operation with the absence of energy‑intensive heating, AirDoor delivers a significantly lower operational energy footprint than conventional entrance systems, embedding sustainability into the way the entrance performs rather than adding it as an afterthought.

Reduces energy loss and carbon emissions at the entrance

By keeping treated indoor air inside the building and limiting unconditioned air from entering, AirDoor reduces key sources of energy loss at open entrances. This stabilises conditions at the doorway and lowers the heating and cooling demand required to maintain comfortable internal environments.

As both product‑level energy use and system‑level demand are reduced, carbon emissions associated with entrance operation fall accordingly. Energy analysis from a single AirDoor installation at a UK supermarket showed carbon savings of around 15,000 kg of CO₂ per year*, directly linking improved entrance control to measurable emissions reduction.

*Energy analysis from a single AirDoor installation at a UK supermarket showed reductions in average daily gas and electricity use of 154 kWh and 177 kWh respectively, delivering a conservative saving of around 15,000 kg of CO₂ per entrance per year (based on BEIC Conversion Factors).

Supports net‑zero strategies with proven, scalable impact

AirDoor is increasingly used as part of long‑term sustainability and net‑zero programmes, where reducing operational energy use across building portfolios is essential. Its ability to deliver measurable performance at open entrances makes it a practical, repeatable solution for deployment across multi-site estates.

This approach has been independently recognised through an Energy Saving Awards win and by inclusion in the published sustainability and climate strategies of major organisations, including Sainsbury’s and the John Lewis Partnership. Together, this demonstrates that AirDoor is a credible, scalable technology supporting long‑term net‑zero ambitions.
