WHY AIRDOOR > energy Efficiency
Measurable energy efficiency at open entrances
AirDoor reduces energy loss at the entrance by preventing treated indoor air from escaping, while limiting air infiltration to help existing heating and cooling systems operate more efficiently, all while using less energy than traditional overdoor heaters.
How AirDoor delivers energy efficiency
More energy efficient than overdoor heaters
Unlike traditional overdoor heaters, AirDoor operates without any heating or cooling element. Instead, it uses a smart control strategy and variable‑speed fans to detect and respond in real time to external pressure changes, generating an active air plume across the doorway to manage infiltration at the entrance.
By combining the absence of heating with fan output only when required, AirDoor consumes up to 95%* less energy than conventional overdoor heaters. This delivers significant long‑term savings and replaces an energy‑intensive, fixed‑output approach with a far more efficient smart entrance solution.
*Based on the average daily energy consumption during the heating season for an AirDoor installed in a 2 x 2.1 metre doorway versus a comparable over-door electric heater under the same conditions.
Reduce heating and cooling demand across the building
By effectively sealing the entrance, AirDoor limits unconditioned air entering and prevents treated indoor air from escaping. This stabilises conditions near the doorway, reducing the need for existing building systems to work overtime to reach target temperatures close to the entrance.
As heating and cooling demand is reduced, HVAC systems can operate more efficiently across the building. When assessed at a whole‑building level, installing AirDoor can deliver energy savings of up to 54%* when conditioning the main occupied space.
**Energy analysis carried out in Winter on a high street retail store with one AirDoor showed average daily energy consumption of the store pre AirDoor was 149kWh vs 69Kwh with AirDoor installed – a reduction of 54%.
Proven, measurable energy and carbon savings
AirDoor’s energy performance has been independently recognised, being named Ventilation Product of the Year at the Energy Saving Awards. Its ability to reduce energy use at open entrances delivers measurable benefits beyond theoretical modelling.
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).

Additional AirDoor benefits
Performance you can measure
Weather Protection
Active protection against wind, rain and unwanted outside air, delivering consistent comfort and efficiency right across the entrance while freeing up valuable space near the doorway.
Cost Savings
With no heating or cooling element, AirDoor delivers significantly lower running costs than traditional heated systems, offering a strong return on investment and lasting long-term savings.
Thermal Comfort
By maintaining consistent indoor temperatures and eliminating cold draughts at the entrance, AirDoor creates a more comfortable environment for customers, staff and visitors.
Indoor Air Quality
AirDoor limits the entry of dust, pollutants and insects at the entrance, supporting cleaner indoor air and healthier conditions for occupants.
Sustainability
By reducing energy consumption and carbon impact at the entrance, AirDoor helps businesses cut emissions and supports net-zero ambitions without compromising comfort or performance.

FAQs
Can’t find the answer you’re looking for?
AirDoor creates an active, invisible air barrier at entrances, limiting heated or cooled air escaping through open doors, reducing the energy required to maintain internal temperatures.
Yes. By reducing heat loss at entrances, AirDoor significantly lowers the demand placed on heating systems leading to energy savings
AirDoor helps reduce energy use by limiting air infiltration at entrances, supporting more efficient and controlled building operation.
Yes. AirDoor is specifically designed to maintain performance in environments with constantly open or frequently used doors. The active, invisible air barrier it generates limits outside air and related weather infiltrating entrances even with the doors open, making it ideal for retail, supermarkets and other high footfall entrances.
AirDoor enhances overall energy efficiency by minimising energy waste and supporting more effective HVAC operation.
