Hamburg Airport and new Terminal 1

Did you know?

All energy savings at an airport ultimately reduce the emissions of carbon dioxide and other greenhouse gases.
At Hamburg Airport hangar H, heating and lighting energy requirements were reduced by a combination of lowering the heating circulation temperature of the floor heating, reassessing illumination needs and streamlining the opening and closing of the large hangar doors.

What are we doing?

Hamburg Airport made environmental efficiency a top priority in designing its new Terminal 1 building.
Terminal 1 uses a water-based cooling system which is around 15% more efficient that an air-based system due to the substantially better heat transfer and storage characteristics of water.
Another important feature is the ‘thermo-labyrinth’, a system to pre-heat outside air in winter and pre-cool summer outside air.

What is the result?

Using water to cool the space is more efficient than cooling incoming and re-circulating air. In winter, warm water circulates through the same system to ensure year-round comfortable temperatures.
By transferring heat from in-coming summer air to the cooler ground, the thermo-labyrinth reduces the annual energy needs of Terminal 1 by 1,450 MWh.
Furthermore, in Terminal 1, all water needs in the toilets and washroom facilities are met by an energy-saving rainwater utilisation system.
In upcoming years, energy efficiency will be improved by 15-20% across the airport. For that purpose, weak points regarding heating and cooling requirements are checked, alternative energy supply systems are analysed, movement sensors are applied, setpoint values for heating, cooling and lighting are tightened.
