Cities are the world we live. A continuously increasing proportion of people are led to or choose to live in them. They are centers of work, services and leisure. However, cities have problems, e.g. pollution, congestion, lack of green spaces, social segregation… Elements which do not make them sustainable neither for humans who live in them, nor for the environment. A question that arises, is whether design could help cities to face their problems and contribute to the control of climate change?

How urban design, which creates the urban structure, along with a series of other parameters(transport, landscape- nature, energy, water, waste…), can contribute to that direction and offer a more sustainable solution? The model of sustainable urban design, which seems to answer these questions, is the focus of the research. How is this realized in practice? Can this model work? Which is our responsibility as citizens but also as users? The change of the way we understand space, the individual parameters which consist it and the realization of the effect of our daily actions in a city, are the basic components for the success of a plan for a sustainable city.
