Abstract
A topic of interest in sustainable urban planning and regeneration is the lack of
integration of the ‘essential’ or ‘critical flows’ (water, energy,
waste/wastewater).
In the Netherlands the shortage of space within urban planning leads to a
rising demand for multiple use of ground and the intensification, or
‘densification’, of existing city districts and neighbourhoods. This process of
densification can be considered positive for urban areas with lower densities, for
it can improve the quality of the urban area and can improve the environmental
efficiency of the public services. However, existing city-parts, invisible
infrastructures and social structures are being aggravated due to this
intensification. Furthermore, less public open spaces are to be included in future
designs concerning these areas. This is also due to cut backs in maintenance
costs and disposal of existing dispersed and fragmented parts of ‘lost’ monofunctional
areas. In summary, one can say that the ecological and spatial
conditions in and around cities are under pressure: transportation distances grow,
protection and qualities diminish, and (infra)structures get more complex, less
robust and less visible. There is however a possibility to revalue the liveability
and ecological quality of open space in and around cities. The use of
decentralized systems at district or local scale could introduce new urban
functions to mono-functional and diminishing (green) areas and options for selfsufficiency.
This paper will focus on another background concerning urban planning
based on ‘Decentralized Concentration’: The need for interconnection of
essential urban infrastructures and ‘red/green functions’ based on another
network philosophy and use, to achieve real (lasting) sustainable urban
development. It focuses on network geometry and related backgrounds for
design, integration and implementation of sustainable solutions concerning the
essential flows at the scale of an urban district, a cluster of houses and individual
houses.
Keywords: urban typology, self-sufficiency, decentralization, energy and sanitation.
