    Socio-Economic and Development Disparities Over the Long-Run: Exploring Spatial Heterogeneities in the Case of Turkey
    (Hungarian Central Statistical Office, 2024) Doğan, Fehmi; Duran, Hasan Engin; Karabakan, Berfin; Dogan, Fehmi; 01. Izmir Institute of Technology; 02.02. Department of Architecture; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture
    The aim of this paper is to explore the evolution of socioeconomic development and income disparities and convergence patterns across Turkish provinces, emphasizing the impact of spatial heterogeneities. We propose two types of contributions to the literature. First, most of the studies that apply the 13- convergence method presume a unique 13 parameter, assuming that all regions homogenously converge to the steady state at the same pace. However, we argue that relaxing this assumption by way of considering spatial heterogeneities might be more informative. Second, we provide a simple solution to a severe problem: The neoclassical model assumes a monotonic saddle path along which economic fluctuations are not considered, which might be particularly influential with regard to convergence when the time span is too short to capture long-term evolution. Many empirical studies cover only short periods, which may be easily dominated by recessions or expansions, significantly biasing the results. To overcome this problem, we look into two datasets covering long periods (1963-2017 and 1975-2021). Having applied various empirical methods, such as spatial regressions, GWR and nonparametric regressions, we obtain several results. First, at the country level, there is empirical evidence of regional convergence and decreasing development inequalities. Second, however, this convergence process is not valid in all areas. We conclude that there is nonnegligible spatial heterogeneity that should be taken into account in such analyses.

    Factors Affecting Tourist Visits To Archaeological Sites in Turkey: a Spatial Regression Analysis
    (Lodz University Press, 2023) Avcı, Ali Berkay; Duran, Hasan Engin; Duran, H.E.; 01. Izmir Institute of Technology; 02.02. Department of Architecture; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture
    The study focuses on the factors affecting visitor numbers to archaeological sites in Turkey. The aim is to investigate the geographical, economic, and demographic factors underlying the visits using statistical methods. The study covers 117 archaeological site visits in 2019. Although existing studies analysed determinants of visits to archaeological sites of different countries, the evidence needs to be explicit. Methodologically, the classical linear regression models are primarily applied in the literature, whereas the incorporation of spatial dependence has largely been ignored. This study contributes to the literature by employing demographic, economic, and climatic factors and spatial relations between the sites. Therefore, spatial autoregressive (SAR) and spatial error models (SEM) are developed in the analyses. According to the results, WHL inscription and distance to the city centre are crucial factors for the visits. In addition, the study emphasizes the significant negative effect of spatial dependence on visitor numbers of archaeological sites near each other. © by the author, licensee Łódź University – Łódź University Press, Łódź, Poland.

    User Satisfactions on Visual Comfort and View Quality Based on Colours and Opacity of Glazing To Control Daylighting
    (Znack Publishing House, 2023) Kazanasmaz, Zehra Tuğçe; Duran, Hasan Engin; Kazanasmaz, Zehra Tugce; 02.02. Department of Architecture; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    Windows are both components that open to the outside and gates that bring the outside elements inside as well. The visible view through windows affects users' perception of the indoor environment. Visual comfort is a key concern to create qualified interior spaces. Glazing type in naturally lit environments becomes very substantial for comfort. As glazing technologies develop, the options available for users have also increased. This study aims to find out how different glazing and view types impact user perception and satisfaction in the interior and to create design ideas for the spaces to be completed in the future. A room with various glazing transmittance (20 %, 50 %, and 90 %), colours (blue and yellow), and view types (street and landscape) are modelled virtually in Relux. A survey composed of these rendered scenes from these variations includes four questions. 40 people participated in the survey. Statistical analyses are made using Stata and EViews. Illuminance and luminance are calculated via Relux to discuss quantifiable values and subjective one together. According to the results, as transmittance increase, the rate of people finding the room pleasant and the quality of the view decrease, but a brighter environment shows up. When using tinted glazing, users mark the rooms as interesting, while pleasantness and view quality decrease. A landscape view instead of a street view in the rooms results is a more interesting, pleasant indoor environment, and higher view satisfaction.

    De-Sealing Reverses Habitat Decay More Than Increasing Groundcover Vegetation
    (MDPI, 2023) Frary, Anne; Salata, Stefano; Couch, Virginia; Saygın, Nicel; Arslan, Bertan; 02.03. Department of City and Regional Planning; 04.03.

    Modeling ecosystem services is a growing trend in scientific research, and Nature-based Solutions (NbSs) are increasingly used by land-use planners and environmental designers to achieve improved adaptation to climate change and mitigation of the negative effects of climate change. Predictions of ecological benefits of NbSs are needed early in design to support decision making. In this study, we used ecological analysis to predict the benefits of two NbSs applied to a university masterplan and adjusted our preliminary design strategy according to the first modeling results. Our Area of Interest was the IZTECH campus, which is located in a rural area of the eastern Mediterranean region (Izmir/Turkey). A primary design goal was to improve habitat quality by revitalizing soil. Customized analysis of the Baseline Condition and two NbSs scenarios was achieved by using local values obtained from a high-resolution photogrammetric scan of the catchment to produce flow accumulation and habitat quality indexes. Results indicate that anthropogenic features are the primary cause of habitat decay and that decreasing imperviousness reduces habitat decay significantly more than adding vegetation. This study creates a method of supporting sustainability goals by quickly testing alternative NbSs. The main innovation is demonstrating that early approximation of the ecological benefits of NbSs can inform preliminary design strategy. The proposed model may be calibrated to address specific environmental challenges of a given location and test other forms of NbSs.

    Adapting Cities To Pluvial Flooding: the Case of Izmir (türkiye)

    In the coming decades, climate change will be one of the most significant challenges for urban areas. The quantity, duration and intensity of events, such as flash rains and heat waves, will increase the vulnerability of urban regions while exposing citizens to potentially dangerous conditions. According to the current literature, mainstreaming resilience in urban planning means designing rules that strengthen urban systems’ adaptive and self-regulating functions by reducing their vulnerability. In this work, we aimed to build knowledge for the application of the sponge district concept to Izmir (Türkiye), one of Europe’s most vulnerable areas to pluvial flooding. To do this, we first analyzed the runoff in each urban sub-watershed, then employed a composite index to determine potential areas of intervention for nature-based solutions. Results show that 10% of Izmir’s urban areas are extremely vulnerable to cloudbursts, which means that 40% of the urban population is exposed to this phenomenon. Moreover, the runoff calculation in the sub-watershed demonstrated that the potential flood volume is underestimated, especially in the upslope areas. The results can be used as a template to suggest a stepwise approach to mainstream the resilience of densely-inhabited coastal urban catchments.

    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.

    Historical collective shelters, yahuthanes or cortejos, are an alternative form of housing that were developed to provide secure sheltering of the groups who were disadvantaged in terms of economic, social, and cultural aspects in the Ottoman city. They have played a significant role in history as a building type that made possible cohabitation of groups, with moral and material problems, and struggling to maintain their integrity despite hardship. This study deals with a group of historical collective shelters in the traditional commercial center of Izmir dating mainly to the late 19th and early 20th centuries. The objective is to understand the historic evolution of collective shelters (yahuthane, cortejo) in Hursidiye, Kurtulus and Sakarya neighborhoods of Konak district in Izmir, to define their cultural values, to analyze their social and spatial development, to present their physical characteristics and evaluate their preservation problems. Eleven collective shelters were documented in the studied site, which is a portion of the traditional commercial center of Izmir (Kemeralti). The site comprehends the ruins of the Roman Agora and the remains of the public buildings dating to the pre-modernization period of the Ottoman Empire as well as the late Ottoman urban layout. As a method, the preliminary studies were reviewed, the land registers were surveyed, the present base map together with the historical maps were overlapped and the case studies were conducted using conventional techniques of architectural and urban conservation. The study has documented the interaction of Muslim and Jewish communities and how the collective living habits of these ethnic groups living in collective shelters differed from standard residential life at the end of the 19th and beginning of the 20th centuries in the traditional commercial center of Izmir. Though collective shelters in the historic center of Izmir have been studied in the literature, their specific location on the map was not available. This study has provided locations of the shelters and evaluated the architectural characteristics of their remains. The traces and remains of the historic collective shelters should be preserved as elements contributing to the integrity of the multi layered city.
