CPH City & Port Development Copenhagen
Masterplan woon- en werkgebied
Copenhagen is an attractive and dynamic city which is rapidly expanding and changing. By 2025 the numbers of inhabitants will have grown by 45.000. This calls for a clear vision how to incorporate new houses and enterprises in the region. The city faces several challenges how to realize these new developments. In recent years increased commuting in the region has put the infrastructure under great pressure. By
2025 car traffic will be up for 30-40% if nothing will be done to prevent it. Nordhavnen is intented to counter the trend to increased commuting in the region and facilitate new housing and enterprises. Because of the close proximity of the inner city, Nordhavnen can set new standards on sustainable urban development and put Copenhagen on the global map of leading environmental metropolis. In order to meet these ambitions, we have defined two conceptual elements which together form the hart of our proposal:
The eastern waterfront of Nordhavnen is linked with the inner city of Copenhagen by a series of iconographic bridges which together form a powerful connection between new and old Copenhagen. A scenic route through various public spaces along the waterside will stimulate people to either walk, cycle or use the public transport. The waterfront promenade will be one continuous carpet of vivid mixed programs such as city beaches, museum, hotels, offices and housing, sports and events. Stretching from the cruisers terminal to Island Brygge and even further to Sydhavnen, the promenade will be a true landmark in Copenhagen. It will become a significant part of more sustainable lifestyle of the people of Nordhavnen.
The containment of CO2 and the efficient usage of world’s natural resources can both be addressed at the scale of urban planning.
With the recycling of waste and solar energy comes another important topic for sustainability: water. This element can, when taken into account at the very beginning of urban design, contribute to a sustainable environment. Grey and black water from households and other dwellings can be recycled into irrigation water (for the greenhouses for example). The condensation from these structures can, in turn, be filtered into drinking water. These energy sources can be fully implemented if and when the urban design takes into account all its necessities. This is precisely the reason why a network of canals has been introduced in the design of Nordhavn and why, on four central locations on the site, large greenhouses have been projected. Furthermore, these components generate urban conditions of great value. Sustainability is thus not only achieved by reducing the usage of motorized vehicles (although we applaud the idea), but implemented as a core structure for urban planning.
One of the sources of CO2 emission is the motorised vehicles.One of the areas in which this emission can be contained and reduced to a minimum is car parks. An efficient way of reducing this emission is by letting trees absorb the CO2. By combining these two functions, an interesting structure emerges: a car park underneath a contained garden or greenhouse. The emissions of the cars are filtered by the trees and the oxygen can then be released to the atmosphere. The greenhouse in itself offers a greater contribution to the topic of sustainability (and to urban program, but we’ll deal with that later). A greenhouse captures solar energy. This energy can be captured in a collective heating system which then provides heating for –for example- households on one hand and energy through Micro turbines. Energy can also be generated through the usage of gasifiers which ‘digest’ waste from the cruise ships and the dwellings. By introducing such a system on site, transportation of massive amounts of waste can be avoided. The biogas emitted is captured to be transformed into energy. The emitted CO2 can then be reduces through the greenhouses. A third source of energy is the seawater: although the water has a low temperature, only a few degrees need to be subtracted from the sea in order to heat –for example- household boilers. The residual heat can be returned to the sea without affecting biological life (quantities are simply negligible).
The system simply works as an inverted fridge.
Waternetwork as a core structure for urban planning
To make Nordhavnen sustainable the constant temperature of the surounding water is used to generate energy. The existing docks are perforated in order to let water reach deep into the urban fabric. New and exciting network of canals, docks and marina’s will form a firm casco on which the new city is built. Furthermore the water will be of an additional value for all the new neighbourhoods and the public space. Water not only improves the image of Nordhavnen and makes it sustainable, it also enriches the flora and fauna on the site.
