Un edificio esistente è un residuo del passato, sopravvissuto al presente, incarna il passare del tempo e lo rivela attraverso riferimenti fisici e non solo. La combinazione del carattere della struttura e delle esperienze di vita danno una ragione per proteggerla e trasmetterla alle generazioni future. Gli studi degli ultimi anni dimostrano che c’è stata una crescente tendenza verso la conservazione degli edifici esistenti. Tuttavia, le indagini hanno rivelato che la scelta della corretta operazione per una struttura specifica richiede uno studio approfondito e strategie adeguate all’utilizzo delle informazioni raccolte. Sfortunatamente, molti progetti risultano con applicazioni inappropriate a causa della mancanza di strategie operative. Di conseguenza, molti edifici di carattere storico sono minacciati dal calo del loro valore, deterioramento o addirittura estinzione. Tutto questo porta all’esigenza di generare linee guida che aiutino i progettisti a selezionare trattamenti di conservazione adeguati. Le strategie operative per gli edifici esistenti mirano a fornire continuità del contesto nelle ere future rispettando la loro identità. Lo studio dimostrerà possibili strategie che cercano di adattarsi a qualsiasi tipo di edificio esistente con varie caratteristiche. Nonostante ciò, tutte le operazioni potrebbero non essere adatte ad ogni singolo progetto, ma il progetto potrebbe utilizzare più di una alternativa operativa. Il progettista lavorerà al progetto seguendo le procedure standard che aiuteranno a fornire la giusta strategia. Le strategie proposte si dividono in cinque fasi. La prima, inizia con un’introduzione che aiuta a comprendere l’edificio esistente evidenziando l’importanza di lavorare con una struttura già costruita e affrontando i tipi e le organizzazioni che ne determinano il valore. La seconda fase è quella del “decision making”, spiega come scegliere un trattamento appropriato, le come la proprietà dovrebbe essere valutata in base ad altri quattro criteri principali. Il processo dovrà anche comprendere un team interdisciplinare esaminando il livello di significatività dell’edificio in riferimento ai tipi di edifici esistenti, la condizione fisica della struttura basata su osservazioni e calcoli, l’idoneità del futuro utilizzo proposto, età, e ancora più importante, i requisiti del codice specificati dalle autorità responsabili. La terza fase riguarda il grado di intervento del team di progettisti in linea con il risultato della valutazione precedente. Il team dovrebbe determinare il suo impatto sulla struttura individuata e decidere il livello di contrasto del nuovo intervento rispetto al progetto del passato. La quarta fase consiste nell’esplorare il tipo di trattamento di conservazione più adatto tra i quattro metodi tipici: conservazione, riabilitazione, restauro, ricostruzione e, quindi, scegliere uno o più metodi di progettazione in relazione al trattamento selezionato. La tesi termina, applicando quanto sopra, con un progetto chiamato “Chiesetta di San Giorgio” spiegando come le strategie proposte si possano applicare ad un sito esistente. In conclusione, le strategie operative hanno l’obiettivo promuovere progetti importanti e di valore storico, dimostrando le misure essenziali per conservare un edificio esistente e sostenere gli interventi progettuali con una rappresentazione chiara, con classificazioni, diagrammi, casi studio e l’applicazione finale del progetto.

Abstract
An existing building is a remnant of the past and survivor of the present. It embodies the passage of time and reveals it through physical and other references. The combination of the structure’s character and the life experiences give a reason to protect and transmit it to future generations. Studies in recent years demonstrate that there has been a growing amount of attraction towards the conservation of existing buildings. Yet, the investigations have constantly revealed that choosing the right operation for a specific structure requires extensive study and proper strategies to use the collected information. Unfortunately, many projects result with inappropriate applications due to the lack of operational strategies. As a consequence, many significant structures are under the threat of depreciation, deterioration or even extinction. This indicates the necessity for guidelines that lead designers to select proper conservation treatments. ‘The Operational Strategies towards Existing Buildings’ aim to provide continuity of the context in the future eras while respecting identity. The study will demonstrate possible strategies which can correspond to each existing building types with various characteristics. Therefore, all operations may not fit a certain project, but the project may end up with more than one operational alternative. The designer will work on the project by following the standard procedures which will help to provide the right initiative for the project. The strategies proceed in five steps. The first part starts with an introduction which assists to understand the existing building by highlighting the importance of working with an already built structure and it continues by addressing their types and the organizations that determine their value. The second step is called ‘decision making.’ In order to choose an appropriate treatment, the property should be evaluated under four main criteria. The process is undertaken by an interdisciplinary team and it examines the significance level of the building in reference to the existing building types, the physical condition of the structure based on observations and calculations, the suitability of the proposed use to this time and age, and more importantly, the mandated code requirements that are specified by the responsible authorities. The third step is the designer team’s intervention degree in line with the result of the previous evaluation. The team should determine their impact on the situated structure and decide the contrast level of the new intervention to the former design.
