For the purposes of regeneration of the consolidated city it is increasingly important
to have the knowledge of the micro-scale distribution of the vulnerability of the population to
the consequences of climate change and increasing urbanization. The work to be presented starts
with the creation of maps of the risk classification induced by the heat islands in the city of
Parma, and aims to investigate which are the most effective strategies that a Public
Administration can adopt. The maps that have been created allow to assess the risk for the fragile
population at the level of the single building. They relate the climatic datum of thermal variation
with the population residing within each building, and verify the causal relationship with the soil
sealing and with the morphology of the urban fabric. The results of the study can help to identify
the thermal hot spot, receivers of specific mitigation actions. The risk map is itself a tool to
develop multilevel actions, designed according to the peculiarities of the sites, where the possible
adaptive solutions are compared with the physical and morphological characteristics of the
places. The positive function of green infrastructures (contrast of overheating, flood mitigation,
creation of places and services with a recreational function) is acquired by research and urban
planning practice. It is equally well known the difficulty faced by Local Authorities in the
maintenance and increase of unbuilt public areas, fundamental for the connection of ecological
networks
