    Decoding 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, Özüm
    People 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.

    Emerging Concept of Human Centric Lighting in Literature Review
    (IEEE, 2023) Kazanasmaz, Zehra Tuğçe; Köse, Fatma Büşra; Tayfur, Gökmen
    Human centric lighting is an umbrella concept which covers human health and well-being in general. As the conventional lighting techniques are based on horizontal workplane illuminance, it drives from the vertical eye level illuminance and its spectral distribution triggering the non-visual effects on humans. That is named as melanopic illuminance consequently. Its metrics have taken their place in lighting design literature and applications, with emergence of related standards subsequently. This literature overview contributes about the understanding the meaning human centric lighting due to transition from visual to non-visual effects of light, and how they direct recent research through light's impacts on human performance, emotions health and well-being, and relations to energy saving even. The shift from the concept of human centric lighting to circadian lighting design is obvious in very current studies. © 2023 IEEE.

    Daylight Performance and Lighting Energy Savings of Amorphous and Crystalline Silicon Solar Cells in an Architecture Studio
    (IEEE, 2023) Taşer, Aybüke; Kazanasmaz, Zehra Tuğçe
    Semi-transparent photovoltaic (PV) glass increased its popularity due to its energy and environmental advantages, which can generate electricity on-site and utilize natural daylight. They use thin-film solar cells to allow daylight to enter space and generate electrical energy. Crystalline and amorphous silicon (a-Si) solar cells are the most prominent in literature and industry due to their high efficiency and sufficient transparency. This study aims to assess the daylight and lighting energy-saving potential of thin-film crystalline and a-Si photovoltaic glass in an architecture studio in Izmir, Turkey. The simulation engine applied two types of solar cells on existing windows to evaluate the advantage of such glass for daylight performance and lighting energy consumption. Spatial Daylight Autonomy (sDA), a climate-based annual daylight performance metric, evaluates the daylight performance of the studio. Research findings note that such solar cells enhance the visual comfort of occupants and the daylight performance of the studio. In addition, crystalline silicon solar cells can cover the studio's whole lighting loads in the summer and fall seasons and balance them up to 66% and 23% in the spring and winter seasons, respectively. These have higher transmittance and peak power, thus; resulting in higher energy and daylight performance. © 2023 IEEE.

    Heritage tourism plays an important role in preserving cultural heritage and promoting local development. The advent of digital technologies has brought about a revolutionary transformation in the conservation and tourism of cultural heritage, redefining the way heritage sites are experienced and shared across global audiences. This study presents a literature survey on the role of digital technologies in developing the heritage tourism sector. The literature review highlights the difficulties of traditional documentation methods and the limitations in recording details of heritage artifacts. In response, digital techniques such as 3D scanning and photogrammetry emerged as essential and practical tools to create accurate and detailed representations of architectural structures and artifacts. These technologies enable remote access to heritage sites as a reliable way to share cultural heritage with a broader audience. In addition, the effect of virtual reality (VR) and augmented reality (AR) applications on heritage tourism is emphasized in the study. Such digital technology applications encourage an engaging experience by allowing visitors to explore historical contexts and past civilizations virtually. In addition, the presentation of digital information on physical environments enriches the visitors' experience of making sense of heritage sites. Furthermore, the study demonstrates the importance of interactive multimedia exhibits and storytelling in interpreting heritage. These exhibitions blend traditional museum displays with digital technologies, enabling personalized exploration and enhancing bonding with cultural heritage. Online platforms, virtual tours, multilingual translations, and digital access initiatives play a significant role in appealing to diverse audiences, thus expanding the scope of heritage promotion. Overall, the study highlights the critical role that the integration of digital technologies into heritage tourism plays in preserving, presenting, and relating to cultural heritage.

    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, Alper
    A 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.

    Lighting Quality and Work Performance Based on Glazing Types and Dynamic Led Lighting
    (IEEE, 2022) Köse, Fatma Büşra; Tayfur, Gökmen; Duran, Hasan Engin; Kazanasmaz, Zehra Tuğçe
    The 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.

    Interactive Imagery and Shared Mental Models in Design Learning
    (Insider Knowledge - Proceedings of the Design Research Society Learn X Design Conference, 2019, 2021) Yazıcı, Gizem; Doğan, Fehmi
    This study explores the relationship between interactive imagery and shared mental models in a design learning environment. The study focuses on design, design learning, and the cognitive components of design. In this research, conceptual project development processes of third year architecture students, in a design studio where four instructors gave desk critiques on a rotational basis, are examined. Within the scope of the study, interviews were conducted with four students and four studio instructors. The process was analysed and interpreted based on the collected data and interviews. It is argued that interactive imagery and shared mental models, which are shaped in the studio's desk critiques, juries and panel reviews, affect the students' conceptual project development. It is possible to conclude that if there is more than one studio instructor giving desk critiques on a rotational basis, students may have both advantages and disadvantages.
