The green reconstruction of urban environments instead of the existing brownfields, open and public spaces, mobility infrastructures and in general grey infrastructure is finalised to a better use of soil, to a multifunctional usability of public
resources and to increase the robustness of urban environments.
5 Experimental Case Study: South Milan
In this scenario, the south-east sector of the metropolitan area of Milan has been
identified as an applicative case for design experimentation and the testing of the
evaluation model proposed and defined by the study. This choice is related to many
factors: indeed, this urban sector has undergone important transformation processes,
is well equipped with infrastructure for local and supra-local mobility (Mussinelli
and Castaldo 2015) and is also directly connected to the rural fringes and the Agricultural South Milano Park (Schiaffonati 2019; Tartaglia and Cerati 2018). Moreover, in this sector, in coherence with the strategic view of the Municipality (VVAA
2017) regarding urban resilience, many experimental projects and activities have
been funded and activated.
8 In the meantime, it shows the main environmental criticalities that characterise the city territory and the Po valley, such as air pollution, the
sewage system during acute meteorological phenomena, periods of drought and an
increase in temperatures during the summer period, with urban canyons as well.
The whole sector has been analysed to identify areas of criticality where regeneration interventions can be proposed through the use of NBS (Fig. 1).
Specifically, the activity carried out concerned the morphological/typological and
functional aspects (building heights, green areas and trees presence, public and private assets, presence of urban canyons, relationships between green areas, total surface area between permeable and impermeable surfaces, etc.), together with reliefs
on the materials characterising the paving and vertical fronts of buildings and other
structures above ground, as well as the solar exposure of open public spaces (streets
and squares) during the summer period. All the analyses have been codified through
the GIS tool, in such a way as to conform to the modelling tool of the urban microclimate (with ENVI MET software), according to stratigraphy and materials that
characterise the open spaces and buildings (Mussinelli et al. 2018b).
8 Among the different initiatives, the project “Sharing cities” for the experimentation of smart
and integrated solutions in the area of Porta Romana; the competition “Reinventing Cities” (area
of via Serio) for the realisation of an innovative building with regard to the reduction/zeroing
of the carbon footprint in which the ABC Department was involved in a participating team as
environmental experts (Andrea Campioli, Elena Mussinelli, Monica Lavagna, Andrea Tartaglia,
Davide Cerati, Giovanni Castaldo, Anna Dalla Valle, Serena Giorgi and Tecla Caroli); the project
“OpenAgri: New Skills for new Jobs in Peri-urban Agriculture” in the area of Porto di Mare-Parco
della Vettabbia; the “100 Resilient Cities—Urban cooling” resilient workshop to explore resilient
urban cooling solutions and technologies appropriate and coherent with communities’ expectations
with the participation of the ABC Department (Elena Mussinelli, Davide Cerati).
