La prestazione energetica con gli strumenti GIS
No full textLa prestazione energetica degli edifici, i relativi fabbisogni ed i consumi energetici sono temi ormai dibattuti sia nel settore delle costruzioni che in quello immobiliare. La Direttiva 2002/91/CE ed il suo recepimento hanno di fatto posto l’accento sull’incidenza che l’edificato ha sui consumi energetici, ben prima della rivoluzione della “Green Economy”. La certificazione energetica degli edifici ha contribuito a diffondere la valutazione degli edifici in termini prestazionali e “comunicativi”, anche a fini immobiliari. Appare chiaro inoltre come l’enorme mole di informazioni a carattere estremamente eterogeneo necessiti fin da subito di un sistema di integrazione dei dati che consenta successive analisi statistiche e di valutazione dell’accuratezza, rappresentatività e propagazione dell’errore, anche nella rappresentazione geometrica e cartografica. L’ambiente GIS consente in questo senso la più ampia prospettiva di integrazione e di elaborazione delle informazioni
Sistema di Accreditamento e Certificazione Energetica (RER). Prime valutazioni in ambiente GIS estese al caso studio di Ferrara
No full textThe new policies about energy performance of building, including minimum energy requirements and EPC (Energy Performance Certificate), are apply to new and existing building, especially in case of energy retrofit. The introduction of EPC database in Emilia-Romagna is an opportunity to start new GIS studies and simulations.
This paper, about Ferrara historical center, aims to debate on the one hand, the number of heritage buildings and their incidence from the energy point of view and, on the other hand, the typology factor for energy saving
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
Coconut fibre insulators: The hygrothermal behaviour in the case of green roofs
No full textCoconut fibre insulators represent an insulating material considered as ‘‘exotic”, which clashes with the
scepticism of his thermo-hygrometric behaviour, particularly in the case of covering technology such as
green roofs, which is a technological solution often adopted in the case of sustainable buildings or nearly
zero energy building. Green roofs represent a valid constructive solution with high thermal performances,
adopted both in existing and new buildings. The purpose of the research regards the study of
the thermo-hygrometric behaviour of the concrete (CLS) and Cross-Laminated Timber (CLT) slabs, insulated
with coconut fibreboards (CF) such as an alternative of synthetic insulator, referred to 10 different
green roofs scenarios. The results show that coconut fibre insulations are equally comparable to natural
and synthetic materials, and the doubts for their applications, including the green roofs, are related to
technological solutions for the implementation in the market and their diffusion between the buildings
materials, rather than their hygrothermal features
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
TECHNICAL SYSTEM HISTORY AND HERITAGE: A CASE STUDY OF A THERMAL POWER STATION IN ITALY
No full textAmong the less explored aspects of the history of the buildings, with a few honourable exceptions in
Anglo-Saxon literature, is the history of technical systems (heating, wiring, lift, artificial lighting, etc.). Yet
technical installations are one of the most important aspects of differentiation of traditional architecture
from the modern age, along with the introduction of concrete, steel, glass and other products of
industrialisation. Technical systems also present a diversification in the manner of use of the building, even
old ones, which are equipped with facilities. Finally, the types of systems, because of their transience and the
absence of specific historical culture, risk falling into oblivion, on the basis of trends imposed by external
factors (energy efficiency or the availability of cheap energy, for example). Therefore, we have taken into
consideration a thermal power station built in the 1930s in a rationalist building in Forlì (Italy), with the
intention of studying and preserving the approach
Il miglioramento dell’efficienza energetica dell’edilizia preindustriale di base: approccio conoscitivo e strumenti innovativi per il governo delle trasformazioni
No full textThis contribution aims to present the synthesis of an ongoing research, developed in two different PhD dissertations, regarding the improvement of energy efficiency of buildings, when it comes to dealing with the complexity and heterogeneity of the urban fabric for the pre-industrial basic building. In particular, a learning and operating approach is developed, which allows to recognize the physiological limit of transformability of the preindustrial basic building characteristics for energy performance enhancement, beyond which a process of incompatible alteration is implemented. By preindustrial basic building is meant the product of a building process which is the result of a non-codified practice preceding the industrialization of the components and the organization of the process itself; it is designed for residence purposes and it is the result of a spontaneous development of building types. The study identifies a methodological and interdisciplinary approach which is consistent with the principles of restoration, suggesting terms, concepts and learning modes at territory level, in order to orient the process of restoration currently adopted for the intervention on preindustrial basic building. Furthermore, we developed instruments which are useful to learn and manage the transformations at the territory level. These instruments target also administrations and political decision-makers, in order to direct energy and territory planning policies which are compatible with the historical context
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
