In France 600 km² of land are built on every year. In addition, the increase of built-up land is four times faster than population growth. This massive and probably unnecessary urbanization leads to a significant loss of agricultural and natural areas, which are essential to maintain. The urban environment is home to over more than half the world’s population, consumes about 75% of energy resources and generates 80% of greenhouse gas emissions. Urban areas, highly energy consuming, are increasing up every day, mainly at the expense of agricultural areas and contributes to the degradation of the ecological footprint. Moreover, the compactness that characterised the cities of the past has for many decades now been abandoned, as typified by the dormitory towns and tower blocks of the fifties. The city is, by definition, a place where you need to promote exchanges and interactions between residents in order to contribute to their further cultural and general development and progress. As urban planners, we have to ask ourselves the question: how can we build the sustainable city of tomorrow? What are the most effective urban forms to create an efficient city in terms of space and energy consumption, whilst respecting the lives, development, progress and culture of the people. This is a reality, the concern for sustainable development should not clash with architectural and landscape heritage. On the contrary, the principles of sustainable development must be carried out simultaneously with the redevelopment of the old neighbourhoods, which are often synonymous with urban environmental quality and liveability.EnglishopenAccessconferencePaper225-229
