LOOP - THE COPENHAGEN SUCCESS FORMULA FOR PEOPLE-CENTRED URBAN EXPANSION

Share page

Since the early 2000s, the City of Copenhagen has been developing the Nordhavn area with a total size of 3.6 million m² through the company By & Havn; Nordholmene - Urban Delta is one of the largest urban development projects in Northern Europe. Over a period of 40 years, the industrial port area will be transformed into an archipelago of neighbourhoods in which active mobility will be given priority and the supply of renewable energy will be consistently implemented.

Gradually, land is being developed and port activities are being relocated to expand urban growth, including on artificial islands in the Örseund. Since 2019, Camilla van Deurs has been the city architect of Copenhagen, an advisor to politicians and (technical) administration on the topics of architecture, urban planning and the environment, and she keeps an eye on the master goals of CO2 neutrality by 2025 (Copenhagen's climate plan "CPH 2025") and thus circular economy and mobility, as well as the targeted development of diverse housing supply. In addition to the ambitious sustainability goals, for which Nordhavn received the DGNB Gold certification, a share of 25 % of price-reduced rents is to be obligatory in residential projects. In new buildings, a parity share of flats up to 50 m² is to be created in order to be able to offer suitable housing for single people as well.

Green Loop & Blue Bays - Intelligent Grid & Cultural Heritage

The planning and architectural offices Ramboll, SLETH, Polyform and Cobe - the latter themselves located in the inner harbour of Nordhavn - jointly won the competition for the master plan of this conversion in 2008. In accordance with the Danish formula for success, the planning principles focus on human needs while anticipating future environmental conditions and technologies.

The zoning into distinctive districts is continued over existing canals and harbour basins and accentuated with the help of fillings and canal buildings to form an archipelago with island-like neighbourhoods, whereby the character of the individual zones is to be formulated in their idiosyncratic cultural heritage through adaptive reuse of formative existing buildings.

The green-loop, a planning pattern and spatial-functional loop, will connect the islands to each other and to the city centre via a green bicycle expressway, giving preference to active mobility and surrounding it with recreational public space. At each location, one will reach a public transport connection within five minutes and the individual neighbourhood sections will be interspersed with green corridors. These will be laid out radially from Urban Greens, i.e. still highly cultivated green spaces, in the parts close to the centre to Natural Greens in the outer areas. This combination of green and blue city - close to the water and permeated by nature - prioritises quality public spaces, ranging from promenades and parks to pocket parks as recreational hideouts, which allow for a small escape in everyday life.

The Intelligent Grid underlies the development planning as a dynamic planning principle. The islands are again planned in subdivided plots and the density of development and mix of functions are coordinated in such a way that open-city and dense-city aspects complement each other effectively; a combination of high-density development and looser areas, intermixed with housing, offices, retail, and cultural/public uses.

Århusgadekvarter - nucleus of future development

With the development of the inner North Harbour area, a solid reference area has already been created in Århusgadekvarter from which future development will be driven forward. The design of Sundkaj by SLETH symbolically shows the new direction. The wooden walkway serves as a public, connecting space of the neighbourhood, giving priority to pedestrians and cyclists and opening access to the water.

With the Silo, Cobe have adaptively converted the former grain silo into residential and public uses, with a restaurant and an event and exhibition space on the ground floor. The crystalline-edged façade made of galvanised steel plates meets air-conditioning standards and at the same time ensures the visual appeal of this landmark.

In the immediate vicinity of the silo, JAJA Architects with Konditaget Lüders have lent further meaning to a multi-storey car park by transforming the roof area into a sports and leisure facility. The façade, which in addition to its greening effect also functions as access to the roof, is symbolic in its design for the Red Neigborhood, as it is called because of its originally predominant clinker brick construction of the harbour buildings. Reliefs along the stairways cite the history and future of the area.

Energylab Nordhavn

The structural development of the harbour is accompanied by a smart energy reallaboratory project, EnergyLab Nordhavn, which was mapped via a public-private partnership chip of twelve project partners and currently continues as an association organisation. The neighbourhood's energy system is tuned to renewable energies (wind and solar), with volatilities in energy availability being balanced out via a smart system of buffer storage. Battery storage built into the car park, a heat buffer storage at the cruise terminal and smart home technologies enable water and heating to be heated when the supply is at full load, thus storing energy in a decentralised way in households as well. EnergyLab Nordhavn proves how intelligent real-time data analysis can be used to display electricity and heat production from renewable energy sources and brings the sharing concept to the energy sector. The experimental components, infrastructures and contractual relationships of the cooperations serve to demonstrate the possibilities and as a model for further neighbourhood projects.
