NUOVE PROSPETTIVE DI SOSTENIBILITÀ PER LA RIQUALIFICAZIONE DEL PATRIMONIO STORICO CON ELEVATI VALORI TESTIMONIALI

Il caso studio del Padiglione di Sant Manuel dell’Hospital de Sant Pau a Barcellona

I processi che perseguono gli obiettivi di salvaguardia di tutte le manifestazioni passate dei manufatti edilizi presentano una forte componente di sostenibilità rispetto ai fattori ambientali, economici e sociali, intendendo, per questi ultimi, anche la componente di valorizzazione degli aspetti culturali e testimoniali. Le attività connesse con la conservazione, la manutenzione e il recupero degli edifici storici diventano, dunque, azioni sostenibili e, pertanto, possono essere valutate attraverso gli strumenti e i metodi pertinenti a tale contesto. A tale proposito, l’intervento sul padiglione di Sant Manuel dell’Hospital de Sant Pau di Barcellona è stato valutato attraverso l’applicazione del rating system LEED® 2009 New Construction and Major Renovation al fine di evidenziare le criticità di applicazione di uno strumento generalmente utilizzato per l’architettura di nuova costruzione o per le ristrutturazioni importanti di edifici recenti.

NEW HORIZONS OF SUSTAINABILITY FOR HISTORIC HERITAGE RESTORATION WITH HIGH CULTURAL VALUES

The case study of Sant Manuel pavilion of Hospital de Sant Pau in Barcelona

Processes aimed at preserving buildings previous expressions have a strong sustainability connotation related to environmental, economic and social aspects, meaning also, for this last factor, the enhancement of cultural values. Activities connected with restoration, recovery and reuse of historic buildings become sustainable actions and, thus, may be evaluated with instruments and tools that are appropriated with this context. With this purpose, the restoration of the Sant Manuel pavilion of the Hospital de Sant Pau in Barcelona has been assessed with the LEED® 2009 New Construction and Major Renovation rating system, aiming at highlighting criticalities and potentialities of an instrument that is generally used for new buildings or for major renovations of recent ones. The building, commissioned to the modernist architect Lluís Domènech i Montaner and built between 1901 and 1922, was based on the hygienist ideas of the late19th century hospital buildings, an approach that strongly believes that the purity of the air breathed by patients (achieved by assigning a large volume to each one and by a strong ventilation) can have a strong impact in decreased mortality and increased recovery rates. The result is an exceptional project in terms of extension and quality, declared by UNESCO as a Heritage of Mankind, that is now undergoing a restoration process. In the research activity, the restoration process on the case study has been evaluated through the application of all prerequisites and credits of the LEED® rating system, an internationally recognized tool for environmental sustainability assessment. The result is a gap analysis that reveals many points of strength, but also some weaknesses and some omissions, in particular related to the restoration process.
