If it’s true that technological development is certainly an important pillar of sustainable design, however the same is insufficient, if not preceded and supported by a proper urban and architectural planning.
The cities we live in are sources of environmental degradation, consume resources and produce waste. Now it is necessary to re-establish a proper balance between the built and natural environment.
Sustainable cities do not consist only of buildings with energy-efficient but also of planning of the urban areas to ensure ecology, economy, social relations and psychologically sustainable environments.
Analyzing the current state of urban areas it is clear that the critical issues are due to poor planning and management of urban transport and to lack of policy integration of parking and mobility policies.
Cities are organized to enable and support the use of private transport, the city is developed to support mobility flows arising from the activities in it localized.
The research work done so far has enabled us to provide a complete picture of the delicate but complex issue of urban sustainability.
To identify the main problems, the research started from the analysis of the current state of our cities; once identified the problems, it was analyzed the causes; the research has focused on the theme of sustainable mobility.
Given the relevance of the theme and the interest forwarded to it by designers and planners, it was possible to identify a number of projects developed following the principles of environmental sustainability and, although each urban intervention appears governed by different planning options, in all cases there is a particular attention paid to the issue of mobility.
Among the major urban models analyzed: the district Solar City in Linz, Austria, the Vauban district in Freiburg, Germany, the seven projects Ecocity, Bad Ischl (Austria), Barcelona - Trinitat Nova (Spain), Gyor (Hungary), Tampere - Vuores (Finland), Trnava (Slovakia), Tübingen - Derendingen (Germany) and Umbertide (Italy), the Greenwich Millennium Village, London, the Masdar City, Abu Dhabi.
For urban sustainability it is essential a drastic reduction in the number of private cars, an increase of public transport, and the provision of pedestrian and cycle paths.
Today there are already several design choices that , from the stage of planning, were aimed at the realization of sustainable urban areas. It has also emerged that sustainable choices do not apply only to projects ex novo but, with right design choices and government of the territory, it is possible to intervene on existing sites (historic center, area, industrial area, virgin area, etc.).. The study of these cases is therefore possible to identify some guidelines to follow for sustainable urban planning and design.
