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 company said. The expansion doubles the size of the existing terminal building with the addition of a new, 300m long pier. Nordic said it continued the timeless architectural expression and rational simplicity of the original airport, whilst introducing new design elements to enhance the passenger experience. Nordic also updated the existing train station at the airport enabling 70% of all passengers to access the airport by public transport. The design increases the airport capacity from 19 million to an anticipated future capacity of 30 million.
The multi-disciplinary design team applied a 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 winters in an on-site depot to be used as coolant during the summer, as per the statement. 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 and by choosing environmentally friendly materials, and Nordic said the building’s CO2 emissions were reduced by 35%. 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, and artificial lighting is designed only as a minimal supplement to high levels of natural daylight, according to the company. “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,” Gudmund Stokke, Founder and Head of design at Nordic-Office of Architecture commented.
