Assessment of Daylighting Strategies in Selected Convention Centres for Improved Sustainability
Get PDFThe study aims to assess the extent to which daylighting strategies are implemented in selected
convention centres. The objectives are to identify daylighting strategies utilized in selected convention
centres, and evaluate their adequacy. The study focused on convention centres as they are commercial
buildings that consume large amounts of energy. Three convention centres were conveniently selected at
random in Lagos State, Nigeria due to the easy access for observation. The study used the mixed-method
approach. 100 questionnaires were issued to respondents in each centre and 131 were retrieved and used
for analysis. The data collected were descriptively analyzed using the Statistical Package for Social
Sciences (SPSS), and the results were sorted from the highest to the lowest in terms of their mean item
score (MIS), and presented in tables. The sizes and functions of the identified strategies in the case studies
were analyzed in relation to standards, and the findings were discussed in relation to other researches. It
was revealed that the selected convention centres did not utilize daylighting strategies effectively as they
rely largely on artificial lighting. The findings further revealed that daylighting is not very well considered
at the conceptualization stage of this building typology. The pieces of evidence show that as the elements
in a space are considered, adequate daylight can enter that space and create the potential for energy savings
in lighting. Further studies can be carried out in existing convention centres in other developing countries
to explore the influence of daylighting on energy savings. This paper provides valuable information on
acceptable daylighting strategies based on the observations made which could be incorporated in
convention centres from the design stage, and insight into measuring the adequacy of daylighting strategies
in convention centres in comparison with other researchers’ findings as discussed below
Assessment of Daylighting Strategies in Convention Centres: A Review from 1990 to 2023
Get PDFThe main goal of a convention center is to provide a productive environment for different events, which they must do by meeting energy efficiency and sustainability requirements. Being a commercial building, it is known for consuming energy in large amounts, which should be mitigated to ensure sustainability. Daylighting is a significant technique in contemporary architecture that contributes to building energy savings, helps to reduce dependence on artificial lighting, provides connections to outdoor spaces, and influences users’ comfort. The study aims to investigate and review the daylighting strategies that are used in convention centers. To achieve this, literature, articles, and websites were reviewed to better understand daylighting and how it is applied in this building type. The study adopted a systematic review and discussed the results descriptively, and it showed that this technique is rarely used in this building type. This could result from a lack of daylighting consideration at the conceptual stage of the building design. Hence, it is recommended that designers understand this technique in order to properly implement it in convention centers and other building types. Further research can be carried out on how daylighting influences user comfort and satisfaction in other building types for adequate implementation in modern-age construction
IMPLEMENTATION OF DAYLIGHTING STRATEGIES FOR IMPROVING USERS’ COMFORT IN THE DESIGN OF A CONVENTION CENTRE IN MARYLAND, LAGOS
Get PDFDaylighting is a significant factor in the design consideration of a building because of its many benefits and advantages. It increases productivity in office workplaces and enhances the wellness of the users of the space. It can also improve users’ thermal and visual comfort. Convention centres are large commercial buildings that utilize large amounts of energy to provide a lot of lighting which can affect indoor comfort. Implementing daylighting in this building typology can help reduce energy cost, load, and demand, and improve the thermal and visual comfort of users. This study examined the daylighting strategies that can be utilized in the design of a convention centre to improve users’ thermal and visual comfort. The study created new opportunities for improving the design of convention centres and other built environment and is useful to architects and other relevant professionals. Questionnaires were used to gather data from the users of the selected buildings, and case studies were carried out to gather information on the entirety of convention centres in Lagos State, Nigeria, and other countries. The data gotten was analyzed descriptively using IBM Statistical Package for the Social Sciences. It was discovered that in many convention centres, daylighting was not appropriately considered, and many respondents lack knowledge of daylighting elements due to their lack of common use. The available elements were found to have mostly negative effects on thermal and visual comfort. Implementing daylighting more frequently can help increase adequate use and knowledge on daylighting, as well as improve users’ comfort

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
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
