Sustainable design of buildings
Get PDFThe research project EFIResources: Resource Efficient Construction towards Sustainable Design, supports European policies related to the efficient use of resources in construction and its major goal is the development of a performance based approach for sustainable design, enabling to assess resource efficiency of buildings in the early stages of building design.
This report focusses on development of the performance based approach for sustainable design, enabling to assess resource efficiency of buildings, is in line with the assessment of safety criteria of the European standards for structural design.
The proposed approach, which is based on a standardised procedure for LCA, aims to harmonize the sustainable assessment of buildings in Europe and to enable an easier integration of structural and sustainability criteria into the design process, thus coping with the basic requirements for construction works of the Construction Products Regulation.JRC.E.4 - Safety and Security of Building
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Model for Life Cycle Assessment (LCA) of buildings
Get PDFThe project EFIResources: Resource Efficient Construction towards Sustainable Design, focusses on the development of a performance based approach for sustainable design, enabling to assess resource efficiency of buildings, in the early stages of building design, and supporting European policies related to the efficient use of resources in construction.
The proposed approach aims for the harmonization between environmental criteria and structural criteria in the design of buildings and thus, it provides the chance for structural engineers to foster a more efficient use of resources throughout the life cycle of buildings and reduce the environmental impacts of construction works.
The work plan of the project is organized into the following main tasks:
• Task 1: Development of a life cycle model for the assessment of buildings, which will enable the benchmarking;
• Task 2: Identification of best practices and development of a set of benchmarks for residential and office buildings;
• Task 3: Development of an approach for sustainable design consistent with the reliability approach of the Eurocodes;
• Task 4: Recommendations for standardization and guidelines for sustainable design.
This report focuses on the development of the model for life cycle analysis (LCA) and on its implementation into a software tool. This model will be used for the benchmarking of the environmental life cycle performance of the structural system of buildings.
The model is applied to common construction materials, at the material level, and structural systems, at the building level, to provide additional guidance in its application and to identify main limitations.
Therefore, some limitations are identified but these affect mainly other building components rather than the structural system of the building, which is the main focus of the developed model.JRC.E.4 - Safety and Security of Building
Environmental benchmarks for buildings
Get PDFThe research project EFIResources: Resource Efficient Construction towards Sustainable Design, aims to support European policies related to the efficient use of resources in construction and its major goal is the development of a performance based approach for sustainable design, enabling to assess resource efficiency of buildings in the stage of design.
In the proposed model for sustainability design, the performance of the building, focussing on resource use, is benchmarked against standard and/or best practices.
This report focusses on the framework for the development of benchmarks for life cycle performance of buildings and provides a preliminary set of reference values for residential and office buildings.JRC.E.4 - Safety and Security of Building
Variations on the Author
Get PDF“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
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
