London Gatwick Airport welcomes over 40 million passengers per year. With the airport experiencing high footfall through ground-floor lobby entrances, the doors are frequently opened, exposing the terminal to the external environment.
The airport’s 3.6m-wide entrance has no internal doors. During the winter, when the terminal concourse was being heated, the presence of a significant stack effect through the stairwell to the upper floors escalated the thermal exchange of air throughout the space from the influx of cold air.
This made it difficult to sustain a comfortable internal temperature, especially during cold winter weather.
The CPA Group team conducted a detailed site survey, recommending the Enershield Air Barrier technology.
Like all Enershield Air Barriers, the system creates a highly effective seal across open doorways by re-circulating facility air in a laminar (smooth) flow.
The kinetic energy generated creates a barrier which prevents leakage of air between two areas with different pressures and climates.
Enershield Air Barriers help to:
This Durashield Air Barrier was custom-designed and manufactured to precisely fit each internal lobby door. It was also strategically positioned across both openings horizontally.
Post-installation, our team carried out temperature measurements and compared them to pre-installation findings.
They deactivated the Enershield Air Barrier and reported a rapid decrease of up to 7°C. Having seen this impressive outcome, Gatwick Airport planned to further optimise its HVAC systems near the entrances to elevate the internal temperature and improve the comfort of passengers and staff.
NB: An independent CFD or computerised fluid dynamic report was commissioned by the client to help understand how a Durashield Air Barrier performs under set conditions compared to alternative outdoor heated technologies.
It’s clear to see that the Durashield Air Barrier has helped London Gatwick Airport achieve stable and comfortable internal temperatures, successfully separating the two environments, despite their high footfall.
