Il contesto edilizio italiano è caratterizzato da una vasta e diffusa presenza di edifici storici, la cui ri-qualificazione rappresenta un nodo critico per il raggiungimento dell’efficienza energetica del patri-monio costruito, con conseguente riduzione delle emissioni di CO2. Il presente lavoro di tesi si inseri-sce in questo quadro generale attraverso un caso di studio relativo al progetto europeo “UIA Ope-nAgri – New skills for new jobs in Peri-urban Agricolture”. In particolare, esso risulta finalizzato alla valutazione delle prestazioni termico-energetiche di due strategie di involucro, da integrare nella ri-qualificazione energetica degli edifici di Cascina Nosedo, uno storico complesso rurale situato nella periferia sud di Milano. Per poter condurre valutazioni sull’involucro, è stato necessario costruire un modello parametrico dell’edificio; la presente tesi propone un percorso di progettazione che ha por-tato alla sua definizione, disegnato opportunamente rispetto allo specifico caso di Cascina Nosedo, volto a bilanciare una riqualificazione energetica efficiente con la necessità di conservazione e valoriz-zazione del bene culturale. La metodologia proposta si snoda in tre passaggi fondamentali: analisi del contesto territoriale e culturale; progettazione del modello architettonico ed energetico; analisi e confronto tra diversi scenari di involucro.

Abstract
Italy is characterized by widespread and diffuse presence of historic buildings throughout the country; the energy retrofit of which, is a critical node of the process towards high performance buildings and the reduction of global emissions of CO2. The thesis work lays in this general framework through a case of study related to the European project “UIA OpenAgri – New skills for new jobs in Peri-urban Agricolture”. In particular, it is aimed to the evaluation of the thermal energy performance of two envelope strategies, to be integrated in the energy retrofit of Cascina Nosedo, an historic farmhouse located in a peripheral area in the south of Milan. In order to carry on the evaluations on the envelope, the construction of a parametric building model was necessary; this thesis suggests a design path that has led to its definition, properly developed in relation with the specific case of Cascina Nosedo, balancing the will of an efficient energy retrofit with the necessity to conserve and enhance the value of the cultural good. The methodology proposed consists of three fundamental steps: Acknowledgement of the context and its cultural relevance, design of the building model matching the project directives, analysis and comparison of different envelope solutions.File | Dimensione | Formato | |
