To promote the renewal and sustainable requalification of social housing in Lombardy means to carry out research in order to identify solutions as efficient and effective as possible, which do not involve the demolition of the building but promote its enhancement. Today it is possible to intervene on existing buildings with new strategies which give all-round and multipurpose solutions to the general issues, using techniques that go beyond punctual interventions and extend the useful life cycle of the built environment. The seismic upgrade must be at the basis of every project within construction. Thanks to an adaptive exoskeleton system it is possible to innovate the architectural image, to support an equitable and sustainable development based on the prevention and risk management connected to unexpected seismic events and to guarantee aspects of structural safety and physical integrity of the users, to improve the morphological, spatial and typological organization of buildings. By using an exoskeleton system, it is possible to innovate the architectural make-up, to support an equitable and sustainable development based on the prevention and the risk management connected to unexpected seismic events. A way to take into due consideration the now unavoidable aspects of structural safety and physical integrity of the users. This paper, part of a Departmental Study, presents the first guidelines to the renewal of social housing buildings owned by Aler Bergamo, Lecco, Sondrio on Piazzale Visconti in Bergamo.

The paper introduces the "BECOMe" project, winner of the PoliSocial Award 2018. BECOMe deals with sustainable affordable housing in developing countries. In particular, the research aims to deliver an integrated development plan for a new business ecosystem design model oriented to new sustainable settlements in Mogadishu (Somalia), involving local entrepreneurship, social facilities and renewable energies. Indeed, the topic of sustainable affordable housing in developing countries is gaining increasing importance for Somali and international stakeholders. Nowadays, the major gap in the provision of adequate and affordable housing is to build a social community and to go beyond just providing basic shelters, to create sustainable durable settlements. The fragile and uncertain nature of the social, political and economic context, characterized by the lack of common shared legislative references and business strategies within the housing sector, makes Mogadishu a complex and challenging reality to be explored and improved.

The role of student housing in academic formative paths is rapidly changing and increasing in importance. According to international trends, university residencies are shifting their function from mere dormitories for students to more open structures for urban territories and the local population and are starting to be considered as important opportunities for enhancing and revitalizing the peripheral and problematic contexts in which they often are located. The case of the Politecnico di Milano is emblematic, due to the large investments the university injected into this sector over recent years, leading to the opening of three new residencies in the suburbs of Milan. This chapter reports on the activities developed by the authors over the last few years, aiming at fostering a more direct relationship among academic knowledge, educational strategies, and urban contexts. This comes via the experimentation of new forms of didactic and research, which attach great importance for university residencies for their possibility to share services, facilities, knowledge among students and the local population. The research focuses on the consequences of this change not only in sociological terms, but also in architectural ones, considering the new implications for the morpho-techno-typological design of structures. The results aim at going beyond the rigid constraints of the current regulation, developing a more open approach to design, which could be a starting point for the advisable revision of the law 338/2000, which is now 20 years old.

The pandemic widened the questions on the typological, functional, and managerial inadequacy of the university housing, highlighting its limits and criticality. A polycrisis that suggests to critically rethink the spatial, organizational, functional, and managerial models, to reflect on the opportunity to open to the needs of new and varied users, not necessarily academics, but above all to broaden the reasoning to the policies tied to the EU internationalization programs. To this end, a new overall vision seems urgent, able to accompany the recovery in terms of innovation, and inaugurate, in competition with the use of the substantial funding of the PNRR, a new season of student accommodation interventions.
