Bel Air

When the airline Bel Air opened their new headquarters and helicopter hangar in Esbjerg in September 2014, special focus was on creating an efficient and reliable ventilation system for the large volumes of space. A hangar places very special demands on air distribution, as the ceiling height is significant and temperature differences can quickly arise between floor and ceiling.

The solution was textile-based ventilation dimensioned to ensure a uniform and controlled air distribution throughout the hangar. Six fabric ducts of 65 feet each ensure a smooth supply of fresh air, while integrated 3/4" nozzles in the ducts actively direct the air into the occupied zone. In this way, heated air is prevented from accumulating under the ceiling and a more stable and comfortable indoor climate is achieved in the areas where the employees stay.

The consulting company NIRAS, which was Bel Air's technical adviser, recommended fabric ducts over traditional steel ducts. The recommendation was based on good experience from previous projects where flexibility, low weight and efficient air distribution had been crucial parameters. At the same time, the competitive price played a significant role in the decision-making process.

In addition, the close and personal sparring around sizing and design was highlighted as an important factor. With the right calculation and adaptation to the size and use of the hangar, the ventilation solution was optimized to both meet the comfort requirements and support energy-efficient operation.

The result is a solution where functionality, economy and indoor climate go hand in hand — also on a large scale and in an environment with special technical requirements.
