Sollihøgda plussby – Europe’s first ’PlusCity’ by COWI
Sollihøgda plussby is an ambitious environmental project aiming to strengthen the future of the Oslo region. Today, the proposed location is an uninhabited forest area. The city will have a train station along the new train line to Bergen, can accommodate 30,000 inhabitants and provide 15,000 jobs, and become Europe’s first plus city.
The vision has four city principles;
Smart city and transportation
The town center and transportation hub will be surrounded by high-density areas with apartments and office buildings. At Sollihøgda, transport methods with the highest social benefits will be put first, with accessibility easiest for those who walk, ride bicycles and travel by bus and train. The project also includes autonomous buses and freight transport, a car-sharing pool, and city bikes.
A city that produces more energy than it uses. Clean and renewable energy production will be distributed and stored through smart micro grids. Zero emission buildings and a city designed with intelligent mobility solutions will decrease the carbon footprint and energy needs substantially.
Portal to the forest
The city becomes a a portal to the forest, and a destination that people will want to visit. Cross-country ski tracks and biking trails will lead straight from the train station and all inhabitants will have a maximum distance of 200 meters to the forest.
The zero-emission society is inspired by natural ecosystems where waste does not exist – everything is a resource. We will design and develop solutions where the technical world can learn from the biological systems, where everything will circulate and make us less dependent on non-renewable raw materials.
Sollihøgda plussby will also nourish an industry that will create an excess of innovation and knowledge about smart city solutions and circular economy that can be exported to other cities in Norway and globally.
