Air treatment units thanks to their design allow to minimize the airport’s gas consumption by regulating indoor air temperature and refreshing it with outdoor air. These units work with large fans and function on multiple levels :

• In the winter, the air is heated by a hot water circuit produced by gas boilers;
• In the summer, the air is cooled by a iced waterproduced by a cooling unit;
• In the summer, by night, a free cooling system introduces cool outdoor air for natural cooling of the premises
• All year long, an innotiative heat pipe system recovers energy from the extracted air in Terminal 2.

To go further on gas consumption reduction, a high-efficiency hot water tank replaced old gas boilers in 2015. In the summer, it provides all the hot water for Terminal 1.

30 m² of solar panels have been installed on Terminal 2. They provide hot water production without the use of fossil fuels. During the summer, the boilers in Terminal 2 are shut down; they are only used in winter for heating purposes.

A 100m3 tank collects all the rainwater falling on around 10,000 m2 roof of Terminal 2. In 2015, the recovered water, which is used for flushing toilets in the restrooms, helped save one-third of the building’s water consumption.

A 50m³ tank has also been installed near the Aircraft Rescue and Firefighting Service (SSLIA) station. It collects the 1,000 liters of water used daily by firefighters during their training exercises. Connected to the station's roof, the tank also captures rainwater. The water is then reused to fill the fire trucks' extinguishing tanks.

Paris-Beauvais airport has recently undertaken an energy audit to identifynecessary improvements for optimizing the energy performance of its buildings. The airport aims to implement innovative solutions to reduce energy consumption related to the lighting of indoor spaces and parking areas and the runway lightning as well.

Translucent skylights have been settled on the roof of Terminal 2 to maximize the use of natural light. They cover 10% of the building’s surface, helping to reduce the airport’s electricity consumption minimizing the need for artificial lighting during the day.
