    Analysis of the Relationship Between Daylight Illuminance and Cognitive, Affective and Physiological Changes in Visual Display Terminal Workers
    (SAGE Publications Inc., 2019) Öner, Merve; Kazanasmaz, Zehra Tuğçe; Leccese, F.; Salvadori, G.
    This study explored the impact of daylight illuminance on cognitive load during visual display terminal use by means of various physiological, performance and subjective measures. Repeated-measures design was adopted to identify the impact of variations in daylight levels that were manipulated through the shading system configurations (shading-on; shading-off). A total of 30 subjects performed visual and cognitive demanding tests. Performance measures were supported by subjective data and eye-related measures during the experimental analysis. Results revealed that the use of a shading system had positive impact on sustained attention. Concerning ocular measures, percentage of eye closure values showed opposite tendencies among vigilance and sustained attention demanding tests. Eye aspect ratio-max and blink duration were significantly correlated with reported glare sensation. In all tests, eye aspect ratio-max was found significantly higher in lower illuminances. Search velocity was significantly correlated with ocular variables in higher illuminances whereas sustained attention showed an opposite trend. This, initially, explains that even slight differences in daylight illuminance might have distinctive effects on the relationship between different groups of assessment variables while measuring cognitive load. Secondly, it proves the significance of carrying out sensitive experiments in terms of both light levels and test characteristics.

    Experimental and Numerical Investigation of Forced Convection in a Double Skin Façade
    (MDPI Multidisciplinary Digital Publishing Institute, 2017) İnan, Tuğba; Başaran, Tahsin; Erek, Aytunç
    Flow and heat transfer of the air cavity between two glass façades designed in the box window type of double skin façade (DSF) was evaluated in a test room which was set up for measurements in the laboratory environment and analyzed under different working conditions by using a computational fluid dynamics tool. Using data from the experimental studies, the verification of the numerical studies was conducted and the air flow and heat transfer in the cavity between the two glass façades were examined numerically in detail. The depth to height of the cavity, the aspect ratio, was changed between 0.10 and 0.16, and was studied for three different flow velocities. Reynolds and average Nusselt numbers ranging from 28,000 to 56,500 and 134 to 272, respectively, were calculated and a non-dimensional correlation between Reynolds and Nusselt numbers was constructed to evaluate the heat transfer from the cavity (except inlet and outlet sections) air to the inside environment and it could be used the box window type of DSF applications having relatively short cavities.

    Corporate Social Responsibility in Construction Industry: a Comparative Study Between Uk and Turkey
    (Emerald Group Publishing Ltd., 2016) Ulutaş Duman, Dilek; Giritli, Heyecan; McDermott, Peter
    Purpose – Corporate social responsibility (CSR) has evolved to an important agenda for many industries and its scope has been widened from the responsible business to strategic decisions. Therefore, the purpose of this paper is to investigate the concept of CSR from the perspective of construction industry by questioning CSR awareness, CSR activities and CSR integration with a comparative case study between UK and Turkey. Design/methodology/approach – Conducting comparative and qualitative research using a case study methodology, this study sets the context for understanding differences in these two countries as to how CSR is perceived and put into practice by selected case firms. Findings – The results revealed that construction companies are aware of the increasing importance of the CSR; however, company scale and the characteristics of the country have great impact on CSR preferences. Despite the differences in the approaches all firms take with regard to CSR domains and CSR types, ethical domain and the social orientation have become prominent for CSR initiatives in both the UK and Turkey. Originality/value – This study provides the empirical evidence for the understanding and integration of the CSR concept in the construction industry; shed light on missing knowledge about CSR integration and serves as a source for further in-depth researches on CSR.
