Terminal 1
Terminal 1 was officially opened in 2005. It was designed by the architectural practice of von Gerkan Marg & Partner, as was Terminal 2. Terminal 1 has a floor area of 6,300 square metres, making it a third larger than Terminal 2. With its dynamically formed roof construction and its light, airy interior space the new Terminal 1 harmonises perfectly with Terminal 2.

While Terminal 2 handles all flights operated by Lufthansa, Condor, Germanwings, members of the Star Alliance and their partner airlines, Terminal 1 serves all remaining scheduled and chartered airlines.
In addition to its impressive architecture Terminal 1 is also distinguished by its innovative, environment-friendly, energy-saving technology. Thus all the water used for flushing purposes in the sanitary facilities is supplied from an energy-saving rainwater usage system. The rainwater is collected on the terminal roof; fed via pipes into a collection system; filtered and pumped into a rainwater reservoir located on the lower ground floor. This enables Hamburg Airport to save 6.5 million litres of drinking water per year.
A thermal labyrinth harnesses natural geothermal energy to supply the terminal with warmer or cooler air, as required. Towers located on the exterior walls of Terminal 1 suck in air, which is then fed into the terminal’s cellar. The ambient temperatures there either warm the air in winter or cool it in summer. The demand on the air conditioning system can thus be reduced, making it possible to decrease CO2 emissions by 400 tonnes per year.
