Conservazione e valorizzazione del costruito per uno sviluppo sostenibile. Il caso del Collegio Spallanzani di Pavia

The presented paper aims to critically analyze the issues of conservation and enhancement of existing Cultural Heritage as a possible response to the objectives outlined by the 2030 Agenda for Sustainable Development. It is focused on university residential buildings, with specific attention paid to colleges, as complex typological systems which, while confirming their absolute functional validity, need to be update. It is in relation to the ever-increasing requests for beds for university students and to the adaptations with respect to performance, distribution, social, cultural and economic needs, required by an increasingly heterogeneous and international class of users. These general and characteristic aspects, at least of the Italian reality, will subsequently be declined on the city of Pavia and on the relationship of its colleges, public and private, with the territorial and urban context and its University. After a general excursus on the heterogeneity of the existing residential buildings, the purpose is to analyze more carefully one of the 11 colleges of EDiSU (Institution for the Right to University Study), the Spallanzani College, with the aim of recounting the historical and architectural events from its foundation up to the most recent typological-functional renewal and energy efficiency policies. The design choices described will be critically analyzed with the aim of bringing out the delicate relationship between funding due to ministerial ones, economic incentives and reports on the feasibility of intervention, use, maintenance and management of an existing historical college. In conclusion, some design principles will be outlined that can also be exported to other existing collegial structures.
