L'ambiente naturale ha sopportato per molti anni il peso di processi edilizi poco virtuosi. L'industria delle costruzioni è responsabile di grandi quantità di emissioni di CO2, di enormi volumi di rifiuti, dell'esaurimento delle risorse e del prevalere di edifici rigidi e non adattabili. Attualmente, circa un terzo dei rifiuti generati nell'UE deriva da costruzioni e demolizioni. (Commission, Construction and demolition waste, 2023) Eppure numerosi materiali di scarto hanno ancora un valore. Purtroppo, a prescindere dal loro potenziale di riutilizzo, finché si seguirà il modello economico lineare, si continuerà a registrare una sostanziale perdita di materiale. Questa situazione deriva dalla mancanza di una progettazione consapevole che consenta una decostruzione non invasiva degli edifici e delle loro modifiche nel tempo. Il legno è un materiale tradizionale che negli ultimi anni ha guadagnato un'attenzione significativa nell'ottica della sostenibilità. Se acquistata in modo responsabile, questa riserva rinnovabile offre un minore consumo di energia primaria durante la produzione e assorbe CO2, consentendo di trasformare gli edifici in serbatoi di carbonio. (Winter, 2003) Inoltre, costruire con il legno ha il potenziale di consentire il disassemblaggio grazie alla sua lavorabilità e leggerezza. Per secoli, molti edifici in legno sono stati progettati con sofisticati sistemi di giunzione che ne consentissero il successivo smontaggio (Zwerger, 2011). Oggi, a seguito dell'industrializzazione, queste pratiche sono state a lungo dimenticate. Le connessioni industriali diffuse hanno ridotto al minimo la possibilità di smontaggio e hanno cambiato il paesaggio della raffinata tettonica del legno. Se si vogliono raggiungere gli obiettivi della costruzione circolare, sarà fondamentale ripensare la progettazione dei nodi e delle connessioni nei sistemi strutturali. È possibile reintegrare i giunti tradizionali in legno nei progetti contemporanei? Questa tesi si propone di esaminare i concetti di costruzione circolare e di progettazione per il disassemblaggio e di esplorare le qualità tettoniche integrali, l'artigianalità e la funzionalità dei giunti tradizionali in legno. Il progetto di tesi indagherà su come queste tecniche convenzionali possano essere integrate nel design contemporaneo, sottolineando il loro potenziale di riutilizzo e flessibilità.

Abstract
The natural environment has been carrying the burden of unreflective building processes for many years. Construction Industry is responsible for large amounts of CO2 emissions, massive volumes of waste, resource depletion, and the dominance of rigid, unadaptable buildings. Currently, around one-third of waste generated in the EU stems from construction and demolition. (Commission, Construction and demolition waste, 2023) There is value to be found in numerous discarded materials. Unfortunately, regardless of their potential for reuse, as long as we proceed to follow the linear economic model, substantial material loss will continue to take place. This situation arises from a lack of smart designs that would permit a non-invasive deconstruction of buildings and their modifications over time. Timber is a traditional material that has gained significant attention in the light of sustainability in recent years. When sourced responsibly, this renewable reserve offers lower primary energy consumption during production and binds CO2 making it possible to transform buildings into carbon sinks.
