Sustainable and energy-efficient rehabilitation of the former hospital of San Salvatore in L’Aquila.
No full textThe topic of sustainable rehabilitation of historic buildings is currently really
important in the town of ’Aquila. After the earthquake of 2009, the project aims in the field of
energy efficiency and the use of innovative technologies and materials are integrated with the necessary reconstruction interventions and with the refurbishment of the heritage buildings.
The transition from a “traditional” to an ecoefficient building takes place more easily and with
greater emphasis in the planning of new buildings, through the introduction of a high potential in terms of experimentation and applied research on building systems and components. The refurbishment of existing buildings raises several questions and presents considerable difficulties, especially when the intervention involves a building bearer of intrinsic meaning and historical, constructive and cultural values.
The former hospital of San Salvatore is a building complex located in the historic center of L’Aquila. It has been left devoid of any function since the end of the twentieth century, so it has undergone a gradual degradation, aggravated by the earthquake damage. The refurbishment of the
building has affected the functional-spatial, figurative, energetic and structural aspects. The
intervention mainly consists of the reuse of the building in order to create a university campus, in the extension of it through new elements that respect the original system, in the replacement of building elements affected by technological problems and in the integration of new elements in the pre-existing building, cooperating with it in terms of structural and energetic performance.
The main purpose of this paper is to define a methodological approach for the sustainable rehabilitation of the historic buildings, by assessment and analysis addressed in the refunctionalization and energy-efficient rehabilitation of the former hospital of San Salvatore in L’Aquila.retracing the steps of assessment and analysis addressed in the refunctionalization and energy-efficient

Management protocol in the building reconstruction process: the case study of the 16th Century Castle in L'Aquila
No full textIn recent years, the construction industry has witnessed a substantial re-evaluation of the way in which all phases of the building process are managed and controlled, particularly the executive phase, thanks in part to the development of innovative technological and computerised tools, in response to the needs of increasingly demanding clients, both public and private, and to the rapid evolution of regulations, which are linked to increasingly evolved concepts of comfort and safety in buildings. This has an impact on the need for designers and contractors to innovate their modus operandi, through better organisation of the work carried out and the adoption of procedures to ensure the quality of the services provided, where there is less and less chance of making mistakes, which would entail losses of an economic and time-related nature.
In the case of the construction process, since the construction site is a unicum in terms of both production and organisation, which escapes any simplistic standardisation, the operational control of management, understood as production efficiency, organisation and management of the construction site, can be validly conducted in parallel with the implementation of BIM methodologies and tools to support Construction Management. These concepts find concrete application in the post-earthquake consolidation and restoration site of a portion of the 16th-century castle in L'Aquila, for which the planning and control process in the digital environment was developed in parallel with the actual execution of the work, since the site was started in the traditional way, with the aim of verifying the deviations between the ideal and actual construction process
Le reti energetiche nei contesti storici: una metodologia per la riqualificazione
No full textstate-of-the-art highlights strong shortcomings in the definition of strategies for the identification of compatible
interventions in consolidated contexts, such as, for instance, the minor historical centres, which characterize the Italian
territory. Among the less investigated aspects in these areas, is the supply, distribution and management of subsequent energy and services. The paper aims at illustrating a conducted research result, focused on the dissemination methods of technological systems in order to improve, replace and integrate technological and energy networks. The proposed methodology was applied in a experimental design at Raiano, a minor village in the Province of L’Aquila
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Comparative Analysis of BIPV Solutions to Define Energy and Cost-Effectiveness in a Case Study
No full textThe built environment remains a strategic research and innovation domain in view of the goal of full decarbonization. The priority is the retrofitting of existing buildings as zero-emission to improve their energy efficiency with renewable energy technologies pulling the market with costeffective strategies. From the first age of photovoltaics (PV) mainly integrated in solar roofs, we rapidly moved towards complete active building skins where all the architectural surfaces are photoactive (Building Integrated Photovoltaics-BIPV). This change of paradigm, where PV replaces a conventional building material, shifted the attention to relate construction choices with energy and cost effectiveness. However, systematic investigations which put into action a cross-disciplinary approach between construction, economic and energy related domains is still missing. This paper provides the detailed assessment of a real multifamily building, taking into account retrofit scenarios for making active the building skin, with the goal to identify the sensitive aspects of the energetic and economic effectiveness of BIPV design options. By assuming a real case study with monitored data, the analysis will consider a breakdown of the main individual parts composing the building envelope, by then combining alternative re-configurations in merged clusters with different energy and construction goals. Results will highlight the correlation between building skin construction strategies and the energy and cost parameters by identifying the cornerstones for enhancing efficiency. The outcomes, related to the total life cost, self-consumption/sufficiency, in combination with different building design options (facąde, roof, balconies, surface orientations, etc.), provide a practical insight for researchers and professionals to identify renovation strategies by synergistically exploiting the solar active parts towards lower global costs and higher energy efficiency of the whole building system
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
