There is nothing very sustainable about air travel, but the airport terminals can be, as has now been proven by the architects of Nordic â€“ Office of Architecture who designed and built a new terminal at Norway’s Oslo Airport. The new terminal is equipped with many sustainable and energy-efficient features and was built using recycled materials.
The new extension to the airport is basically a 984 ft (300 m)-long structure and it provides an additional floorspace of 1,237,849 sq ft (115,000 sq m). It was built using primarily recycled and natural materials, such as recycled steel, curved glulam beams, as well as concrete mixed with volcanic ash. The latter is thought to be more sustainable than regular cement, since lower temperatures are needed to mix it, and it is said to have a longer expected lifespan. The cladding and flooring is mostly oak.
The terminal is insulated to Passive House standards, while they also achieved the BREEAM “Excellent” sustainability rating, which is a first for an airport building. They will also be storing the snow collected off the runways in winter and using it to cool the building in the summer. The curved shape of the terminal also maximizes solar heat gain, while the generous glazing lets in ample amounts of natural daylight and eliminates the need for artificial lighting. Oslo only gets about 6 hours of daylight in the winter months, so I suppose artificial lighting will be needed then. As for heating, the terminal utilizes low-carbon technologies like district heating and natural thermal energy.
Overall, this is a great example of large scale sustainable architecture, which needs to become the norm going forward if we wish to preserve the planet.
