Studio del microclima indoor per la conservazione preventiva di Villa Barbaro, Maser

Nowadays, a deep knowledge about historic buildings is strongly necessary to manage those architectures in a preventive way, to guarantee their conservation. The term ‘management’ has here many meanings and involves several fields, as: sustainability; energy efficiency; the possibility to preserve the cultural heritage, safeguarding the building and – at the meantime – the artworks hosted inside it, its accessibility…all topics connected to the one of the open to the public of a museum, or the free use of a building by the owners, if we are talking about a private house. This paper is focuseed on an analysis work of some of those phenomena on a specific case study: Villa Barbaro, realised in Maser (TV) between 1554 and 1560 by Andrea Palladio (1508-1580) and registred in the UNESCO World Heritage Site list since 1996, as Palladian Villa of Veneto. In this case, the monitoring campaign has been fundamental, because it has allowed to record determinants data for the comprehension of the current conservative problems of the Villa and for the elaboration of design solutions, finalised to. The parameters recorded by the probes during the monitoring campaign are: air temperature; relative humidity; illuminance; and carbon dioxide (CO2). Thanks to the realisation of a virtual building model of Villa Barbaro, it has been possible to create hypothetical scenarios which we could obtain through specific architectural and managemental interventions. Moreover, in this way, it is possible to evaluate the consequences caused by those interventions preventively, on the virtual model, without any risk on the original architecture and artefacts. Another aspect which contributes to characterize the research in innovative ways, is the calculation of a specific index, aimed at determining the ‘aggressiveness’ of the indoor microclimate towards the artefacts: Heritage Microclimate Risk (HMR). Finally, the reading of “I Quattro Libri dell’Architettura” helps to find out many indications (as the thickness of the walls, etc.) by Andrea Palladio, in relation to the microclimate. The focus of the research is the global knowledge of an historic building, under the architectonic and microclimatic point of view, which is useful to have a clear picture of the current conditions and characteristics of a studied building, before proceeding with interventions which could compromise or worse its conservation conditions.
