Approccio tecnologico alla progettazione sostenibile del patrimonio ordinario

This paper presents a teaching experience carried out within the Architectural Technology course in the second year of the Architecture degree programme, focused on the energy and functional retrofitting of the Spirito Santo neighbourhood in Enna, considered as ordinary built heritage. The project activity aimed to promote a conscious and integrated design approach, combining technological, environmental and social aspects. Starting from a critical analysis of the existing buildings—marked by high thermal losses, obsolete construction solutions and limited passive performance—students developed multi-scale intervention strategies involving the building envelope, interior spatial organisation and outdoor spaces. Particular attention was paid to functional redistribution in relation to solar orientation, the reactivation of urban voids and the improvement of universal accessibility, with the goal of enhancing both energy performance and neighbourhood identity.
