L’uso del legno nel settore delle costruzioni può essere una delle soluzioni più adeguate e idonee per la realizzazione di edifici ad alta efficienza energetica con ridotte emissioni di CO2. Il presente lavoro di tesi nasce come risposta ad un bando internazionale per progetti urbani resilienti a zero emissioni di carbonio. Gli obiettivi prefissati dal bando permettono di sviluppare un lavoro basato sull'approccio della progettazione integrata in cui ogni fase del processo è guidata dalle prefissate finalità in termini di sostenibilità. L’approccio multidisciplinare risulta infatti una componente fondamentale del progetto sviluppato, che si è articolato tramite un’interazione di tematiche architettoniche, strutturali, tecnologiche ed energetiche. Il progetto prevede un edificio di nuova costruzione destinato a social housing realizzato a Milano, tipologia di intervento che assume un ruolo chiave per quanto riguarda la sperimentazione di nuovi approcci alla progettazione sostenibile sia dal punto di vista culturale che tecnologico. Il progetto architettonico si è delineato a partire dall’analisi del contesto urbano e delle caratteristiche climatiche, con l’intento di definire le volumetrie e la loro corretta esposizione per arrivare a determinare aspetti funzionali e distributivi basati su concetti di flessibilità e condivisione. Il legno è stato scelto come materiale strutturale dell’edificio e rappresenta un’interessante proposta al fine di raggiungere lo scopo di ridurre le emissioni di CO2 nel mondo delle costruzioni. A partire dall’innovativo sistema costruttivo X-LAM o crosslam (cross laminated timber) sono stati svolti il progetto strutturale e quello tecnologico, trattando le principali criticità e potenzialità, con l’intento di confrontarci con un sistema non affrontato durante il percorso accademico. A livello energetico sono state indagate le strategie passive che possono contribuire al raggiungimento di un edificio ad alte prestazioni energetiche. Le simulazioni sono state eseguite prendendo come riferimento due appartamenti a diversa esposizione e sono state confrontate in termini di consumi energetici per il riscaldamento e raffrescamento.

Abstract
The use of wood in the construction field can be one of the most adequate and suitable solutions for the construction of high energy efficiency buildings with reduced CO2 emissions. The present thesis work was born as a response to an international competition for urban resilient carbon free projects. The objectives set by the competition allow us to develop a work based on the integrated design approach in which each phase of the process is guided by the established goals in terms of sustainability. The multidisciplinary approach is in fact a fundamental component of the developed project, which is articulated through an interaction of architectural, structural, technological and energy themes. The project consists of a new building, built in Milan, whose intended use is social housing, a type of intervention that plays a key role as regards the experimentation of new approaches to sustainable design, both from a cultural and technological point of view. The architectural project was developed starting from the analysis of the urban context and the climatic characteristics, with the aim of defining the volumes and their correct exposure to arrive to determine functional and distributive aspects based on concepts of flexibility and sharing. The wood was chosen as the building's structural material and represents an interesting proposal in order to achieve the aim of reducing CO2 emissions in the construction world. Starting from the innovative X-LAM or crosslam (cross laminated timber) construction system, the structural and technological projects were carried out, investigating the main criticalities and potential, with the aim of comparing a system not dealt with during the academic course. From the energetic point of view, the passive strategies that can contribute to the achievement of a high energy performance building have been investigated. The simulations were carried out taking as reference two apartments with different exposure and were compared in terms of energy consumption for heating and cooling.File | Dimensione | Formato | |
