Energy Efficiency in Buildings. Research Perspectives and Trends.
Full text linkThe 1st International Conference on Buildings, Energy, Systems, and Technology (BEST 2016), was held in Belgrade, Serbia, on November 2-4,2016.
This conference was an opportunity to bring together experts with different skills around the theme of building performance. It covered different aspects (technol-ogy, energy, environment, and economy), different scales (from the urban to the building level, including the built environment up to the single technical building systems), and different phases of the building process (from urban planning to building design, up to construction and management).
This Special issue contains extended versions of some selected papers presented at BEST 2016, which went through a blind peer review of international experts.
The present Editorial introduces the topics of the BEST 2016 and the contents of this Special issue. The focus of the Editorial is the theme of energy efficiency im-provement in buildings; it provides an overview of state-of-the-art and of the leg-islation framework, and a discussion on research perspectives and trends

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

No full textRecently, the issue of climate change has received considerable critical attention. According to the fifth assessment report of the intergovernmental panel on climate change, if the emissions continue to rise, the global average temperature will be 2.6-4.8 degrees Celsius higher than the present, by the end of 21st century. Furthermore, climate change projections express that heatwaves will occur as often as each year by the middle of this century as the climate pattern has been disrupted. In this context, there is an increasing concern that a paradigm shift is likely to happen in the future energy performance of the buildings. As the building sector consumes around 40% of the total energy in the world, reducing energy demand is challenging. Considering the long life span of buildings, this study, therefore, sets out to assess the effect of climate change on Italian typical residential buildings. This study can form the basis for future actions toward the resiliency of the built environment.
In this paper, the study of climate change impacts is carried out by sensitivity analysis of the heating and cooling demand and the risk of overheating under different scenarios using the variance-based model. “Representative Concentration Pathways (RCPs)” 4.5 (stabilization) and 8.5 (business as usual) of emission and concentration scenarios according to IPCC fifth assessment report, have been applied in this study. The analysed buildings have been selected from the IEE-TABULA research project. They represent three building sizes (single-family, multifamily and apartment blocks) for the construction period 1946-1960 in Italy. This period was selected because buildings present a higher energy saving potential compared to other construction periods. Energy simulations were carried out using Energy Plus for the near term (from 2021 to 2040) and long term (from 2081 to 2100). The widely used morphing methodology was adapted for creating future weather data using the existing tool, WeatherSiftTM for Milan (Italy). The results indicate that occupants will experience a high risk of overheating and building energy use patterns will change. The simulations show decreases in heating energy demand and an intense increase in cooling energy demand, as expected. These results underline the significance of considering future weather for energy performance assessment of buildings. Besides, they point out the urgent need to establish building adaptation measures for climate change
