Each network of circular cities that is set up within the framework of InC2 shall operate according to the action principles defined for this instrument and focus predominantly on one of the four priority themes identified:
town planning and construction
Town planning and construction processes allow societal needs and dynamics to be met, but are also intensive consumers of soil, water, materials and energy and responsible for a considerable part of the volume of landfilled waste and air pollutant emissions.
In a circular vision of the city, existing buildings and urban spaces are available resources with economic and social value and rehabilitation is the main form of intervention in the city and of urban development. Spatial planning promotes urban compactness and continuity, rehabilitation, refunctionalisation and improvement of the energy performance of buildings, the qualification of public and collective spaces, and promotes a greater use of urban heritage, enabling the reduction of the consumption of natural resources, soil in particular, as well as the protection of urban landscapes and collective memory. Rehabilitation projects and construction processes are oriented towards reducing impacts and increasing the useful life of buildings, their components and materials. Demolitions are limited and construction waste is managed in such a way as to take advantage of the value of the construction elements and rescued materials, and to foster new business models associated with their recycling and upcycling.
From a perspective of change, cities must define planning strategies and innovative forms of urban, land and local economic development management that enhance the efficient use of public spaces, buildings and urban infrastructure and social cohesion. This includes integrated urban rehabilitation actions, the promotion of the reuse of abandoned buildings and spaces, the qualification of public space and urban equipment, the regulation of new business models in the real estate sector, including new forms of transitional, flexible or shared appropriation of spaces, and new logics of hiring and offering public services and collective spaces. They should also promote the intelligent management of construction waste with innovative solutions and demonstration projects, including material libraries, recovery processes and regulatory mechanisms, and information and awareness raising actions within the sector.
