Article An Analysis of Visitors’ Perceptions of Shopping Malls †(MDPI, 2023) Çavka, Hasan BurakShopping malls have been a significant part of our daily lives for decades. Their significance is derived from the use of these spaces based on great numbers of people, as well as the role malls play in culture. On the other hand, the design of malls has been constantly evolving according to the needs of users and the market. This study is based on survey data that we collected from ninety visitors of a shopping mall located in Izmir, Turkiye. Through the survey, we collected data on topics such as the participants’ visit frequency and reasons for visiting the mall, architectural and spatial features they favor and/or dislike, their opinions on where they perceive malls in everyday life, and their opinions on alternative spaces to malls. The data collection was finalized right before the pandemic, which significantly changed the way we think about public spaces, as well as malls, in relation to architecture. Analyzing collected data provides further insight into surveyed customers’ perception of spaces, the design of shopping malls, the use of the space, the preferred design features, as well as design features that drive customers away from the mall. The analysis was later compared and linked to studies in the literature. These research findings have the potential to be used in studies that evaluate mall design and space use, as well as in studies that compare the post-pandemic perception of spaces and the use of shopping malls. © 2023 by the author.Book Part 1960s Tax Law and Non-Muslim Exodus From Istanbul: Turkification of the City(Taylor & Francis, 2023) Akpınar, İpekThis chapter discusses the urban consequences of the expulsion of Istanbul Greeks in 1964. It demonstrates the urban impact of the 16 March 1964 decree that terminated the residence of 12, 000 Greek passport holders in Istanbul (a population of 40, 000 with their relatives), who were given 24 hours to leave the city and allowed to carry only 20 kilograms of belongings or US$22 with them. The event also alarmed many other non-Muslim families to emigrate from Istanbul, while the city was receiving a large influx of immigrants from rural lands due to the growing industrialization and urbanization. Akpinar discusses the urban planning interventions in Istanbul under the Menderes and subsequent governments throughout the 1950s and 1960s as ad-hoc or intentional steps toward Turkification, in which discrimination and the resulting emigration of Istanbul Greeks played a significant part. © 2024 selection and editorial matter, Esra Akcan and Iftikhar Dadi; individual chapters, the contributors.Conference Object Citation - Scopus: 1Decoding and Predicting the Attributes of Urban Public Spaces With Soft Computing Models and Space Syntax Approaches(Education and research in Computer Aided Architectural Design in Europe, 2023) Yönder, Veli Mustafa; Doğan, Fehmi; Çavka, Hasan Burak; Tayfur, Gökmen; Dülgeroğlu, ÖzümPeople spend a considerable amount of time in public spaces for a variety of reasons, albeit at various times of the day and during season. Therefore, it is of utmost importance for both urban designers and local authorities to try to gain an understanding of the architectural qualities of these spaces. Within the scope of this study, squares and green parks in Izmir, the third largest city in Turkey, were analyzed in terms of their dimensions, landscape characteristics, the quality of their semi-open spaces, their landmarks, accessibility, and overall aesthetic quality. Using linear predictor, general regression neural networks, multilayer feed-forward neural networks (2-3-4-5-6 nodes), and genetic algorithms, soft computing models were trained in accordance with the results of the conducted analyses. Meanwhile, using space syntax methodologies, a visibility graph analysis and axial map analysis were conducted. The training results (i.e., root mean square error, mean absolute error, bad prediction rates for testing and training phases, and standard deviation of absolute error) were obtained in a comparative table based on training times and root mean square error values. According to the benchmarking table, the network that most accurately predicts the aesthetic score is the 2-node MLFNN, whereas the 6-node MLFN network is the least successful network. © 2023, Education and research in Computer Aided Architectural Design in Europe.

These conditions influence occupants' visual comfort and perception. Thus, the design of the glazing component becomes more of an issue. With the emerging smart window technologies, the design options have expanded. These technologies have been investigated mainly in terms of energy performance. This paper presents a literature review of smart windows and their performance on visual comfort and human perception. Experimental studies that conducted measurements or surveys in this field are evaluated. The results of the study showed that with the growing technology of smart windows, it is possible to increase visual comfort and human satisfaction indoors. However, there are performance deficiencies that create particular problems for occupants. The aim of this paper is to collect the studies on smart glazing in terms of visual comfort and human perception and bring out the potential of smart window technologies for human-centric indoors. © 2023 IEEE.Article Citation - Scopus: 6A Field Study on Adaptive Thermal Comfort in a Naturally Ventilated Design Studio Class in the Post-Pandemic Period(Universiti Putra Malaysia Press, 2022) Pekdoğan, Tuğçe; Avcı, Ali BerkayDesign studios are where design students spend most of their time learning theory and practices. For this reason, thermal comfort conditions in studios are crucial to provide a suitable environment for education. Especially in the post-pandemic period, thermal comfort conditions have become more critical in educational buildings. The present study focuses on the adaptive thermal comfort condition in an architectural design studio in the Mediterranean climate of Izmir/Turkey. The study aims to evaluate the comfort conditions of the students and determine the effect of mask use on thermal sensation in the post-pandemic period. For this purpose, air temperature, relative humidity, and air velocity measurements were collected during the studio hours in the spring semester when the heating and cooling systems were not working. Additionally, a thermal sensation survey was conducted with 42 students. The results showed that the thermal comfort level was within the 90% acceptability limits according to the ASHRAE Standard-55. According to the survey results, the use of masks by the students did not have a significant effect on thermal perception. © 2022, Alam Cipta.

That is why indoor air quality at home is essential for public health. Sufficient ventilation is the factor to avoid accumulation of pollutants in indoor air, which include microorganisms, such as SARS-CoV-2. Therefore, adequate ventilation is needed to provide good indoor air quality for human health and reduce infection risk at home. There are no reports of residential ventilation rates in Turkey. In this study, CO2 concentrations were measured in two residences in Izmir, Turkey. Three experiments were conducted to determine background concentrations and the rate of natural ventilation with infiltration and opening windows. Results show that air exchange provided by infiltration is low for both case rooms, while adequate ventilation could be achieved with natural ventilation under the studied conditions. Infiltration provided air exchange and ventilation rates of 0.18 h-1 and 5.9 m3/h for Case 1 and 0.29 h-1 and 8.23 m3/h for Case 2, respectively. Air exchange and ventilation rates were increased to 2.36 h-1 and 76.9 m3/h for Case 1 and 1.2 h-1 and 34 m3/h for Case 2, respectively, by opening the windows. Although ventilation can be provided by opening the windows, the other factors that determine its rate, e.g., meteorological variables, cannot be controlled by the occupants. Consequently, people cannot ensure the good indoor air quality in bedrooms and sufficient reduction in transmission of pathogenic microorganisms; therefore, risk of spreading diseases such as COVID-19 at home.Conference Object The Effect of Lap-Splice Configuration on Seismic Performance of Substandard Rc Columns(fib. The International Federation for Structural Concrete, 2022) Baltacı, Alihan; Gündoğan, Safiye; Demir, Uğur; İlki, AlperA considerable amount of existing reinforced concrete (RC) buildings in developing countries possess vital deficiencies such as incorporating poor quality of concrete and insufficient transverse reinforcement, and use of plain reinforcing bars without proper detailing, such as inadequate configurations of lap-splices at critical plastic hinging zones. While these can affect the strength and ductility of structural members adversely under seismic actions, research on such substandard structural members is scarce. As such, further information is valuable for the assessment of the seismic safety of such substandard columns constructed with inadequate lap-splice configurations of plain round bars. Therefore, this study aims to investigate the effects of different lap-splice configurations of plain bars on the seismic performance of substandard RC columns and contribute to the development of assessment codes for such existing substandard buildings. Towards this aim, three full-scale columns were constructed to represent typical characteristics of substandard RC columns. The columns were subjected to constant axial loading (with an axial load to capacity ratio of 0.3) and reversed cyclic displacement reversals simultaneously representing gravity loads and seismic actions, respectively. The test program included i) one reference column with continuous longitudinal bars (no lap-spliced connection), ii) one lap-spliced column with an overlap length of 20 times the longitudinal bar diameter without any hook and iii) one lap-spliced column with an overlap length of 20 times the longitudinal bar diameter with a 180-degree hook. Test results demonstrated that columns with lap-splices did not reach their flexural strength and experienced more remarkable strength degradation with respect to the column reinforced with continuous longitudinal bars. On the other hand, presence of a 180-degree hook at the ends of spliced bars reduced the negative influence of inadequate lap-splice length in terms of strength and ductility.Conference Object Citation - Scopus: 2Lighting Quality and Work Performance Based on Glazing Types and Dynamic Led Lighting(IEEE, 2022) Köse, Fatma Büşra; Tayfur, Gökmen; Duran, Hasan Engin; Kazanasmaz, Zehra TuğçeThe combination of daylight characteristics and LED lighting quantities determines offices' visual environment. Lighting conditions can influence office workers' health and work performance. This study is an experimental one containing lighting measurements in two offices, subjective performance tests, and questionnaires to find out how work performance, lighting preferences, and satisfaction with lighting quality modify in terms of various glass types and dynamic LED lighting quantities. Glass types have strong impacts on contrast tests on paper and luminance which are corresponding to work performance. Regarding lighting quality, it strongly relates to the homogeneity of light, the impression of artificial light and the perception of objects' textures and color, contrast balance between paper and the surrounding. When the glass was modified in offices, we observed that participants preferred to change the CCT setting of LED by remote control, and in relation to that the eye-level illuminance and SPDs showed significant changes. So, the findings depicted the importance of the choice of glass types concerning LED lighting settings in terms of the above variables.Article Citation - Scopus: 1Outside the House but Not in the City: Promenades in Istanbul as Negotiated Public Spaces for Women in 19th-Century Ottoman Novels(İstanbul Teknik Üniversitesi, 2021) Çil, Ela; Şenel Fidangenç, Ayşe NurDrawing on from feminist literary theory, this article analyses the first Ottoman novels working within and consolidating the patriarchal discourse published in the rampant modernization period in the second half of 19th century, which is also named the Tanzimat (Reorganization) era of the Ottoman Empire. Having Istanbul as their settings, the discourse of the novels tackle with delineating the limits to the social and cultural transformations, which the novels’ writers perceive to be the direct result of Western influence. The novels have a didactic style aimed for guiding their readers to shield certain values, which they think hold the core of Ottoman identity, from the changes. We argue that the discourse of the novels manifest ambivalence regarding the inevitable presence of women outside the house and negotiate with their readers on the place and practices of publicness. No matter how popular and crowded they had then become, the promenades, were where the male writers aimed to confine women in their outings. At one level, their emphasis on the promenades is related with the conceptualization of nature as a safe space in the context of a modernizing city. And, on the other level, they want to keep Muslim women away from Pera, the Westernized and cosmopolitan district, in Istanbul.Conference Object Citation - WoS: 1Citation - Scopus: 2Computational Design in Distributed Teamwork Using: Digital and Non-Digital Tools in Architectural Design Competitions(Education and Research in Computer Aided Architectural Design in Europe, 2019) Erbil Altıntaş, Livanur; Kasalı, Altuğ; Doğan, FehmiThis paper reports a case involving computational practices in design process with an aim to understand the role of digital and non-digital tools in the design process. Following an ethnographic approach, we aimed at understanding the nature of the interactions among team participants which are human and non-human in a distributed system. We focused on computational practices in design process and we aimed to understand the role of digital and non-digital tools in the design process. Tools have remarkable role in a distributed system in the sense of propagation of knowledge. It was observed that form exploration by digital tools may not controlled as much as sketching.
