Text description provided by the architects. Designed by Oslo-based practice Nordic-Office of Architecture, the 115,000 sqm expansion to Oslo Airport sets new standards in sustainability. The competition-winning design, which uses snow as a coolant, has achieved the world’s first BREEAM ‘Excellent’ sustainability rating for an airport building.
The expansion doubles the size of the existing terminal building with the addition of a new, 300m long pier. Nordic continued the timeless architectural expression and rational simplicity of the original airport – which the practice designed in 1998 - whilst introducing new design elements to enhance the passenger experience. Nordic also updated the existing train station, which sits at the heart of the airport enabling 70% of all passengers to access the airport by public transport.
Nordic’s design increases the airport capacity from 19million to an anticipated future capacity of 30miliion, whilst passenger flow was improved with a maximum walking distance of just 450m, far shorter than most airports.
The multi-disciplinary design team applied an holistic approach to sustainability, including the harvesting of as much on-site energy as possible. Snow from the runways will be collected and stored during wintertime in an on site depot to be used as coolant during the summer. Natural materials have been used throughout the building: the new pier is entirely clad in timber sourced from Scandinavian forests. Recycled steel and special, environmentally friendly, concrete mixed with volcanic ash has been used throughout. By choosing environmentally friendly materials, the building’s CO2 emissions were reduced by 35%.
Enhanced levels of insulation mean the project has achieved Passive House level performance standards. Energy consumption in the new expansion has been cut by more than 50% compared to the existing terminal.
Passenger comfort and well-being have been key drivers of the design throughout. Artificial lighting is designed only as a minimal supplement to high levels of natural daylight, and can be set to reflect different moods according to weather, season and time of day. The compact layout of the building, transparency and open spaces enhances visual legibility and wayfinding, providing reassurance and peace of mind for travellers. A panoramic window at the north end of the pier, a 300-metre long skylight and curved glazed windows on both sides open up the view to the surrounding landscape and beyond.
Green walls and water features suggestive of Scandinavian forests enhance the experience for passengers as they move through the terminal. The retail units in duty free areas have been conceived as organic stone forms associated with Norwegian landscapes.
Gudmund Stokke, Founder and Head of design at Nordic-Office of Architecture, commented: “We are delighted to have delivered a project which not only develops Oslo Airport’s distinctive architecture, but one which also provides a greatly enhanced experience for passengers.“
Dag-Falk Petersen, CEO of AVINOR commented: “Oslo Airport is now more spacious, more efficient and more comfortable for the passengers. The expansion project was delivered on time and under budget by the design team.”
Nordic’s team is currently working on ten airport projects in seven different countries. Istanbul New Airport, is scheduled to open next year and, once completed, will be the largest airport in the world.
