Abstract

 In urban planning space for most of the (sustainable) generated energy, water clearance and waste(water)-treatment is found outside the citydistricts or even cities. The distances for transportation of energy, water and waste(water) continue to increase. Broadening the bio-diversity and food production are sometimes even found in other (Eu)regions or countries. The consequence of this need to transport energy, water and waste to centralised plants outside cities and consequently an enormous amount of ‘technical infrastructure’ is an additional use of energy, water and materials. Apart from that, leakages, inclining rotational speeds, changing technologies and aging of existing technical infrastructure will lead to huge problems within 20 to 30 years [1]. Besides, especially the technical infrastructure needed for the transportation of wastewater, warmth and electricity has a non-negligible environmental impact and is a relative expensive feature in urban planning. This technical infrastructure is often situated under the ground and not visible. Therefore the overall involvement of users is little, they don’t see the effects of their habits and the resulting qualities and quantities of the transported ‘flows’. Apart from the need to increase the visibility of the different flows, the costs for the needed infrastructure should be calculated more directly linked to the amount of use or -produced. If the optimum scale for each one of the flows could be found, considerable cost reductions would arise from technical infrastructure which is no longer required, and generating funds for investment in ecological solutions would intensify. The inevitable mixing of different elements is detrimental to the quality. The majority of the transported flows undergo losses during transportation which also has serious impacts on the immediate environment. The way to permanent urban development appears to be elusive. In modern town planning new inventions and the introduction of intelligent light infrastructure are required. In the long term only closed cycles for processes and use of material could result in a permanent and sustainable urban environment. These cycles should be located as close to the users as possible and should be based on passive or natural technologies. The paper focuses on rethinking the urban development as a whole, e.g. including buildings, (technical) infrastructure and the so called ‘suprastructure’. It shows possible reductions in used materials and energy through a renewed way of thinking concerning building site preparation via general ‘lightness’ of needed (re)new(ed) infrastructure by (dis)connecting different flows and their solutions in a more integral way and by finding more decentralised, local and flexible solutions. It shows a reference casus of a realised common housingproject in the Netherlands (with sustainable care) and its calculated environmental impact of the individual houses and the belonging technical infrastructure inside and outside these houses and the entire city district.
