Airport Terminal Extension in Keflavik

In the spring of 2010 the Eyjafjallajökull volcano in Iceland erupted, having a devastating effect on the country. Air traffic in Europe came to a standstill and as a result Iceland became increasingly isolated. Eyjafjallajökull was on everyone's lips, both east and west of the Atlantic, but the eruption turned out to have great promotional value for Iceland. When air traffic recommenced in Europe, tourists flooded to Iceland to experience the exceptional nature and culture of the country. With a population of only 330,000, the years after the eruption of Eyjafjallajökull saw a large number of tourists travelling to Iceland. The amount of passengers traveling through the airport has increased with 30-40% per year, and in 2015 almost 5 million passengers traveled through the terminal. Keflavik Airport terminal opened in 1986, then 23,000m2. Since then the terminal has extended several times, and with the massive increase in the number of tourists traveling through the airport there is a continuous need to expand the terminal fast.

In 2016 the airport extended with a 4.700 m2 busgate terminal. It services passengers to and from the aircrafts by remote stands. By limiting the size of the construction and the amount of service for the passengers it was possible speed up the building process and ensure maximum performance of the building in terms of passenger flow. The building programme is complex as it has to service both Schengen and nonSchengen passengers and also passengers of socalled third countries simultaneously. The layout is simple and rational allowing for a great degree of flexibility. Extensive glass facades allow travellers to engage in the activities on apron as well as having spectacular views to the surrounding vast landscape and mountains. Travellers are exposed to the ever changing Icelandic weather conditions. In the wintertime one can experience the special Nordic light, aurora borealis, and in the summertime the building will be bathed in daylight all day long.

The building is simple in its structure, consisting of a steel frame, prefabricated concrete floor slabs and a glass facade. The simplicity in the building structure was necessary in order to allow for the airport to be fully operational during the construction. The materials and colour schemes for the airport extension are inspired by Icelandic nature. The floors are made of black terrazzo and smoked oak. The interior glass walls are inspired by Icelandic autumn colours that can be found around the Thingvellir National Park. Woven aluminium mesh in natural colours is laminated into the exterior glass façade, acting as a sunscreen and having a positive effect on the indoor climate. This provides improved thermal performance, reduces glare and adds a unique depth in the texture of the façade. It also reduces heat loading and light transmission, potentially saving the building owners capital expenses in relation to heating, ventilation, and air conditioning.
