Satisfy the needs of populations while saving natural resources

Satisfy the needs of populations while saving natural resources

Cities must be designed, built and managed to meet the fundamental needs of all their inhabitants.

Air quality, health

Cities must offer their inhabitants living conditions that protect their health, in particular enabling them to live in an environment that is as free of pollution as possible. Good air quality is certainly one of the main objectives that must be achieved. This assumes that real-time monitoring and alert systems are available, that the development of industrial activities and mobility is managed with this objective in mind and that the internal air quality of buildings that are constructed is the best possible.

The water cycle

Water quality is also a determining factor for human health. Not only must a regular and generalised supply be arranged for cities, but its quality, which can be degraded by multiple elements, must also be assured.

In addition, water being a precious resource, waste must be avoided and there must be a capacity for recovering and treating it in order to return it to consumption.

Energy management

Energy is essential for human life, in particular city life, and its availability is a determining factor in a city's economic competitiveness, as well as for its inhabitants' quality of life. Depending on the modes of production involved, it can have a greater or lesser impact, in particular on air quality and greenhouse gas emissions.

Depending on the manner in which a city is organised, the modes of mobility proposed and the types of construction involved, energy consumption may be significantly reduced without for all that affecting peoples' comfort.

In addition to the actual design of a city, its forms and the distribution of activities that must include the "energy consumption" dimension right from the initial planning stage, the development of renewable energy in the urban area, the recovery of energy generated by the "urban metabolism" and the use of the most energy efficient techniques both in terms of mobility and construction, in particular thanks to the development of smart grids, can be used to combine production, management and the satisfaction of energy needs.


Construction, renovation, building

Ensuring the availability of a diversified and satisfactory housing supply, combatting a precarious or even unhealthy habitat, adapting housing to peoples' life pathway, such are the needs to which cities must respond.

In addition, the building sector constitutes a formidable reservoir for energy saving and the reduction of the greenhouse gas effect, both due to the opportunities for reducing consumption and its capacity to produce renewable energy. Its characteristics also constitute a major element in the comfort of urban life, both in terms of the quality of indoor air and the reduction of sound pollution. It is also a means of contributing to the biodiversity that is essential for ecological balance thanks to clever designs using planted roofs and walls.


Security in cities

A feeling of security and the ability to come and go without restriction are important elements in a city's quality. This preoccupation is an integral part of planning, especially ensuring a social mix in neighbourhoods in order to avoid segregation and ghettoization, but also devising town planning that is not conducive to crime, in particular permitting surveillance and the intervention of the forces of law and order.

Nature in the city

Nature in a city is a factor of urban amenity and an indicator of the quality of the environment. Revegetation and landscaping contribute to the reduction of pollution, the streaming management and fight against the effect of heat islands generated by warming. It also contributes to improve energy efficiency in buildings. Nature in cities also provides citizens with a response to their demands for leisure and amenities. It is also an opportunity for some families to produce part of their own food. It is therefore a major element in city dwellers' quality of life.


Heritage and leisure

Inhabitants' quality of life also depends on their opportunities for leisure and relaxation. This involves the provision of cultural, sporting and show infrastructure but also the capacity to develop and provide access to a city's cultural and historic heritage as well as its natural resources (rivers, etc.). In addition these elements are a source of attractiveness for both economic and tourist activities.
