Studio del microclima indoor per la conservazione preventiva di Villa Barbaro, Maser
No full textNowadays, 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
APPROCCI CONSERVATIVI A CONFRONTO. La Reggia di Venaria Reale a Torino e la Biblioteca Generale Storica dell’Università di Salamanca
No full textLo studio dell’evoluzione storico-architettonica della Biblioteca Generale dell’Università di
Salamanca (Spagna) e della Reggia di Venaria Reale, a Torino (Italia), affiancato dall’analisi dei
dati microclimatici e dall’ausilio della simulazione virtuale, hanno permesso di confrontare gli
esiti di due differenti tipologie di intervento applicate a due distinti edifici storici. La prima
tipologia ricade nella logica del restauro conservativo; la seconda nel campo del recupero,
della valorizzazione e della riqualificazione. Il presente contributo si pone l’obiettivo di
presentare logiche, finalità ed esiti che hanno guidato e caratterizzato entrambi gli approcci
EUROPEAN TRAINING CURRICULUM FOR RESTORATION WORKERS (RE-VET PROJECT). UN PROGETTO ERASMUS PLUS TRA FORMAZIONE E COLLABORAZIONE SUL TERRITORIO.
No full textGli interventi di restauro hanno il fine di preservare il patrimonio storico-culturale e architettonico per poterlo tramandare alle generazioni future. I lavori di restauro architettonico sono normati da specifiche regole e sono guidati da professionisti. Ciononostante, nel panorama europeo, tra gli operai edili impiegati nel campo del restauro architettonico scarseggiano generalmente conoscenze sufficienti per intervenire in piena coscienza sui beni culturali: questa mancanza di cultura diffusa può costituire una minaccia per la conservazione del patrimonio. L’articolo presenta il progetto europeo RE-VET (European Training Curriculum for Restoration Workers), un Erasmus plus che è stato avviato nel 2020 ed è pensato per la fascia di lavoratori EQF4 che operano nei canteri di restauro architettonico in Europa. Il fine, in armonia con gli obiettivi più generali dei programmi Erasmus Plus, è quello di intervenire sulla formazione per colmare le lacune esistenti, per migliorare la qualità degli interventi di restauro sul patrimonio architettonico, contribuendo così alla conservazione preventiva del patrimonio storico-culturale e architettonico in Europa.Conservation projects aim to preserve the authentic cultural properties of architectural heritage in order to hand these values down to future generations. Restoration works on Cultural Heritage require special professional skills and trusting incompetent and inexperienced people is a threat which could affect its conservation. The architectural restoration works are regarded as a part of the construction industry according to specific regulations and they are led by professionals. However, workers involved in the building companies generally lack skills and knowledge on how to handle historic buildings. This paper presents a European Erasmus plus project, started in 2020 and designed for craftspeople who implement works dealing with architectural heritage: RE-VET project (European Training Curriculum for Restoration Workers). It aims at contributing to the skills of these workers in order to increase the quality in restoration works of architectural heritage, thus contributing to the preservation of cultural heritage in Europe using a bottom-up approach
Building Simulation to Measure Indoor Microclimate in Heritage Buildings
No full textThe aim of this paper is to describe our Building Simulation (BS) approach to study indoor microclimate parameters in heritage buildings. Literature already exists over this subject: in the area of museums - Thomson, Camuffo; this issue has been particularly emphasized, for example, by Bernardi; others, as De Guichen, proposed specific methodologies for museums. Nevertheless, in our opinion, today there isn’t a vision which includes the history and the objectives of the architecture. We consider indoor microclimate in heritage buildings as a result of several strategies to guarantee indoor comfort. We named it “Historic Indoor Microclimate”, and we adopt BS to simulate actual, past and future indoor microclimate. In this paper we show three case studies of Italian historic buildings: Villa La Petraia, Florence; Villa Barbaro, Maser; Palace of Venaria Reale, Turin, which can clarify the importance of the application of the BS on cultural heritage. Moreover, the paper proposes an index: “Heritage Microclimate Risk”, useful to study the indoor microclimate aggressiveness
The Study of Historical Indoor Microclimate (HIM) to Contribute towards Heritage Buildings Preservation
Full text linkKnowledge of building techniques, materials and their decay is nowadays quite vast, as
well as on the solutions and methodologies of a restoration project, which depends on the goal of
the restoration itself. Even the choices on the new usage of historic buildings are often well
considered. In the last few years, we have conducted some monitoring campaigns to obtain data
related to four distinct buildings, differing in construction times, typology, location, current and
historical uses. What has been discovered is that these buildings appear to be able to guarantee
historical microclimates surprisingly overlapping to the parameters nowadays considered
appropriate to conserve them and the historical patrimony they contain. In this article we show
some explanatory results of four case studies from our research. The monitoring control, moreover,
allowed us to develop the analysis further, from survey to virtual simulation. In this way it was
possible to verify the effects of minimal variations in the architectural characteristics, such as
opening or closing a window, covering an open yard, or else removing a cover, reducing the source
of light etc. All of these managerial and architectural interventions have a significant effect on the
indoor environment of buildings and can improve the conservation status of architecture,
sometimes to such an extent that more costly and invasive restorations become unnecessary
INDOOR MICROCLIMATE MONITORING: USE AND ISSUES. THE CASE OF THE REALM OF VENARIA REALE.
No full textWith this paper we want to present a methodology for the indoor microclimate monitoring and data analysis, stating the related difficulties and issues. It will be presented the study of the indoor microclimate of two rooms, carried out in the Realm of Venaria Reale. This building is the result of six architects’ work, between 1659 and 1798: Amedeo Castellamonte, Michelangelo Garove, Filippo Juvarra, Benedetto Alfieri, Giuseppe Battista Piacenza e Carlo Randoni. The overarching aim is to involve, in the field of microclimate measurement, applicated on the Heritage Buildings’, the size-time in the subject matter and which permits to obtain new data, useful under the scientific and operational point of view. On this line of thinking, Marco Pretelli e Kristian
Fabbri, have defined a specific field of research: the “Historic Indoor Microclimate” (HIM), which adopts an approach designed to consider the architectural and microclimatic context, starting from the disciplines which define the indoor microclimate study, introducing the study of the physical
variables that determinate the indoor microclimate in a prolonged time dimension. Moreover, the paper is aimed to explain what are the most common issues which you could address during this kind of study, and to propose and to present a new index: the “Heritage Microclimate
Risk” (HMR): the whole data and information that is possible to register by means of monitoring and which allows to identify a magnitude index to assess the HMR. In this way it is possible to evaluate the risk level to whom the goods are exposed and the level of the human’s comfort, to the end to
improve it, in a vision which considers the conservation of goods and the comfort of the users in a coordinated way. Indeed, the best strategy to preserve the cultural heritage is the one that allows to detect in time any potential microclimatic risk, or rather situations where there is a danger due to the
fact that actual parameters of the indoor environment are going beyond the set alert thresholds. The so-called “risk situations” can be determined by physical, chemical and biological factors: principal causes of the degradation.
The study carried out on the two rooms of the Realm of Venaria Reale, includes the analysis of ten years probes’ data; the realisation of a virtual building model; the construction of a virtual environment model and its validation: by comparing the virtual data to the monitored ones. It permits
to evaluate the actual, past and future conditions of the building, its goods and the people thermal comfort conditions. Moreover, we can envisage alternative scenarios, pre-emptively defining which actions could aid the preservation of the good, avoiding the risk component that would be taken
working on the original. All this process entails many issues: about, for example, the data, which could have many gaps and errors, or incoherence, due to some different reasons as the malfunctioning of the probes or of the HVAC system; difficulties finding restoration data and archive documents; establishing the building’s thermo-physical characteristics; managing, on the virtual building model, the UTA (air-handling unit)
and of the set-point data; obtaining information from different actors; etc. In our opinion, it is substantial knowing and thrashing out these kind issues, when you want to work on the field of monitoring and microclimate control
Study of the indoor microclimate for preventive conservation and sustainable management of historic buildings : The case of Villa Barbaro, Maser
No full textIn recent years, there has been an increasing awareness of the need for a proper management of historic buildings, which must be sustainable; energy-efficient; make it possible to ensure the preservation of cultural heritage, whose availability also must be guaranteed. To find this kind of solutions we propose a new concept: Historic Indoor Microclimate (HIM), i.e. the study of any indoor microclimate’s change of an architecture, due to structural or management variation. Moreover, this study identifies a magnitude index to assess the microclimatic risk. The case study presented shows the results of a research carried out in 2016 and applied to Villa Barbaro, Maser, which concerns the evaluation of the indoor microclimate through monitoring and planning of the management of this building. It permits to guarantee a better energy efficiency; the preservation of the historic building and of the collections and artefacts inside it; and to increase the level of visitors’ comfort
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
