Article Citation - Scopus: 1Factors Affecting Tourist Visits To Archaeological Sites in Turkey: a Spatial Regression Analysis(Lodz University Press, 2023) Toköz, Ö.D.; Avci, A.B.; Duran, H.E.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.Article Citation - Scopus: 6Revealing the Climate-Responsive Strategies of Traditional Houses of Urla, İzmir(Sustainable Building Research Center, 2023) Avcı, A.B.; Beyhan, Ş.G.Vernacular houses possess significant climate-responsive properties due to the accumulated information from the trial-and-error method. Therefore, the traditional houses of a region can guide new buildings in terms of adaptation to the climate. The study focuses on the climate-responsive properties of vernacular houses of Urla, İzmir. The study aims to reveal the specific strategies of the traditional houses of Urla in response to the hot and humid Aegean climate. Relating to this purpose, Postane Street, which is among the significant historic streets of the town, is selected as the case area to evaluate the vernacular houses of Urla. The research method is based on the climate-responsive strategies determined from the literature review in the first part. These criteria include “orientation to the sun and wind, the effect of direct sunlight and shading strategy, building envelope and form, interior space organization, integration of greenery, building materials, and roof strategy”. Climate Consultant and Design Builder Software were used to prepare the psychrometric graph and shading regime visualizations. The study showed that the climate-responsive strategies of the street’s vernacular houses are shaped to avoid excessive heat gain in the climate of Urla. The research results are expected to guide sustainable design applications in the same area. © International Journal of Sustainable Building Technology and Urban Development.Article Citation - WoS: 2Citation - Scopus: 2Monitoring Soil Degradation Processes for Ecological Compensation in the Izmir Institute of Technology Campus (turkey)(Mdpi, 2022) Salata, Stefano; Couch, Virginia ThompsonMonitoring changing environmental conditions for short-term periods is a key aspect of adaptive urban planning. Unfortunately, the official environmental datasets are often produced at too large time intervals, and sometimes the speed of urban transformation requires real-time monitoring data. In this work we employed ESRI ArcGIS (ver. 10.8.1) to process two normalized difference vegetation indices for the campus area of the Izmir Institute of Technology (Turkey). The area of this campus constitutes an optimal site for testing whether alterations to the soil due to excavation and new construction can be monitored in small areas of land. We downloaded two different Sentinel acquisitions from the Copernicus ONDA DIAS platform: one taken on 28 March 2021 and the second taken on 13 March 2022. We processed the images while elaborating the normalized difference vegetation index for both years and compared them. Results demonstrate that all major and minor soil degradations on the campus during the intervening year were detected and empirically quantified in terms of NDVI reduction (abrupt changes). These findings confirm that detailed seasonal environmental monitoring of every part of the world is now possible using semi-automatic procedures to process original Sentinel data and recommend site-specific ecological compensation measures.Article Eğitim yapılarında asansör trafik analizi yöntemlerinin karşılaştırılmasına yönelik bir araştırma(Gazi Üniversitesi, 2023) Deligöz, Dostcan; Harputlugil, TimuçinPurpose: Regarding elevator design in educational buildings; It is aimed to investigate the legal framework, to integrate dynamic simulation programs to design process, to compare traditional and dynamic simulation methods, to evaluate the adequacy of elevator features specified in the legislation and to determine the optimum scenarios according to the minimum requirements.Theory and Methods: Based on the findings of the literature review, which examines the issue of elevator traffic analysis together with the legislation and regulations, the carrying capacities of the elevators in the educational buildings designed by the Ministry of National Education (MNE) are tested. The stability of the system is tested by analyzing the conditions where only the disabled, disabled and building workers can be used together and all building users can use the elevators with the dynamic simulation method (with Elevate Software). The limits of the system are determined based on the waiting times during the peak usage periods. The findings of the study are evaluated according to the waiting times determined by CIBSE Guide D and the Chamber of Mechanical Engineers followed by the discussion of the outcomes.Results: The issue of elevator design has been overlooked in educational buildings, and a comprehensive elevator traffic analysis method has not been defined. For the effective use of all occupants, elevator design should be handled comprehensively with considering potentials of dynamic simulation method.Conclusion: According to the findings of the study, it is noted that the number and capacity of elevators in the legislation for educational buildings are determined only for minimum conditions and for disabled users. In addition, the legislation (considering calculation methodology) is not specific for educational buildings but related with buildings in general with public use. Considering the occupants, and their profiles of the educational buildings, a more comprehensive traffic analysis with the dynamic simulation method may enable the elevators to be designed and to be used more efficiently.Article Citation - WoS: 5Citation - Scopus: 6An Investigation of the Design Process's Effect on a High-Performance Building's Actual Energy System Performance(Ios Press, 2022) Terim Çavka, Belgin; Çavka, Hasan Burak; Salehi, M. MahdiThe design intent and the performance targets of projects may sometimes fail to match a building's actual post-occupancy performance. The mismatch of intended and actual building performance can be attributed to multifarious reasons. This study focuses on the role of project decisions made during design as one of the reasons of shortfall. The aim of the study is to unveil the design decision-making process of a state-of-the-art research building through the analysis of project's available set of IDP (Integrated Design Process) documentation. To understand the relationship and correlation between the energy performance gap and the decision-making process of the case building, we investigated the design decisions' effect on the actual performance. The particular emphasis is on the decisions that were based on assumptions rather than measured actual test data for the proposed innovative building systems. The designed heat recovery system, which was dependent on recovered heat from the neighboring research building, had a significant effect on the building's poor energy performance. We investigated collected project data from coordination meetings, thoroughly analyzed project documentation, and quantified the building's actual energy performance data. The analysis of the project information shows the ripple effect of decisions that were made based on assumptions, that triggered shortfalls in the building's overall actual performance. Our qualitative analysis indicates that the poor system performance during operations was related with the design decisions that were not based on the measurement of the actual performance of the existing systems in the neighboring building. The performance of the heat recovery from the neighboring building as a highly dependent Energy Conservation Measure (ECM) analyzed through collected documents and data. The ambiguity of the available heat potential from the neighboring building and related testing issues defined on an explanatory timeline of process coding. The conclusion includes recommendations for the design decision-making process for innovative system integrations for high-performance buildings, and underlines the importance of IDP for complex buildings.Article Geleneksel Konutlarda Günışığı Aydınlığının Değerlendirilmesi: Kula Geleneksel Konutlarında Başoda(Gazi Üniversitesi, 2023) Battal, Cansu; Kazanasmaz, Zehra Tuğçe; İpekoğlu, BaşakDaylighting is one of the main factors among the features that determine the original space qualities in traditional houses. Illuminating the space with daylight also determines its ambience. Daylighting criteria should be considered among the features to be preserved in the usage decisions. In traditional dwellings in Anatolia, the main room is the most lavish room, which has projections and is surrounded by windows on three sides. Therefore, in the buildings which are conserved for reuse, the main room should maintain its original daylighting features. The aim of this study is to draw attention to the maintenance of daylighting features in the restoration decisions of traditional dwellings. Within the scope of the study, daylight performance of the main rooms of Kaçiklar and Zabunlar Houses selected in Kula, Manisa was evaluated. The daylight illuminance of the main rooms was measured during the four seasons; by calculating the ratio of the window area to the floor and wall areas, reflectance of surface materials and normal-normal transmittance of window glass were calculated. Results showed that daylight illuminance of the main room in Kaçiklar House was not sufficient for all four seasons, while it was in Zabunlar House. As a result, while the restoration decisions are developed, opening the closed window in the main room of Kaçiklar House, cleaning the paint on the top windows and and selecting a light-coloured wall finishing material will increase the reflectance value and will positively affect the daylight illuminance; in Zabunlar House, on the other hand, removing the existing wooden glazing in the sofa in order to increase the daylight provided through the sofa and increasing the reflectance value by choosing a light-coloured wall finishing material will increase the daylight illuminance of the main room.Article Citation - WoS: 3Citation - Scopus: 3For Whom the Bell Tolls? Towards a Flexible Concept of Authenticity for Religious Heritage Buildings in Political Conflict Zones–case of Northern Cyprus(Taylor & Francis, 2022) Saifi, Yara; Yüceer, Hülya; Hürol, YoncaThis article discusses the possibility of developing an understanding of the concept of authenticity through the understanding of authenticity in architectural terms, specifically religious heritage buildings in areas of political conflict. Although authenticity has been a continuous subject of debate in the field of heritage studies, however, we argue that difficulties in coming to terms with its application in areas of conflict are still persistent. The study uses the case study of the Agios Synesios Church in North Cyprus, built around the Twelfth century, and is still in use by the Greek Cypriot minorities who continued to live on the island following its division in 1974 and the forced displacement of both Turkish and Greek Cypriot communities to either part of the island. Based on observation of the church and its surrounding context, the research shows that coming to terms with authenticity is problematic for the church since the prolongation of the Greek Cypriot way of life has been compromised due to political fluctuations. The argument suggests that once the authenticity of a religious building is assessed as a heritage asset, a flexible concept of authenticity is essential to consider in areas of political conflicts especially when its original context no longer exists.Article Citation - WoS: 1Citation - Scopus: 1Design of Demountable Reciprocal Frames With New Geometric Properties(Int. Association for Shell and Spatial Structures, 2022) Özen, Gülçin; Kiper, Gökhan; Korkmaz, KorayThis study aims to develop missing geometric knowledge for demountable reciprocal frames (RF). While designing a demountable RF, one should know the initial, in-process and final form of the RF. These processes require some specific geometric knowledge. There are some deficiencies about geometric properties in the previous studies about demountable RFs. In this study, the positions and the orientations of the nexors are found by using the Denavit-Hartenberg parameters. This information gives where the joints are placed, how they are oriented and take position according to one another. Besides, the influence of engagement length on the fan height and the base edge are analyzed. Thereby one will be able to find out how much space the RF covers with the known base edge. With the geometric knowledge obtained from this study, demountable RFs having different engagement lengths can be produced with the same nexors.Article A Novel Design Method of Deployable Semi-Regular Tessellated Surfaces With Plano-Spherical Units(Int. Association for Shell and Spatial Structures, 2022) Maral, Mesude Oraj; Korkmaz, Koray; Kiper, GökhanThe design of movable systems gives an opportunity to create transformable designs which respond to the environmental, functional, cultural, and aesthetical needs of today's architecture. This paper proposes a method for designing a family of deployable structures which can be applied to semi-regular tessellated planar surfaces such as roofs, walls, and shading devices. The generated modular approach and adaptability provides a wide usage area and various combinations for these designs. The regular convex polygon modules are designed as a network of the triangular units. The triangular unit is designed using Bennett's overconstrained plano-spherical linkage topology. The polygonal modules are assembled to each other in one-uniform semi-regular tessellations. The assembly of adjacent regular convex polygons in each tessellation is examined to find a proper solution for no collision during deployment and to properly fit a surface without any gaps or overlaps in the deployed position. The assembly method for creating 1-DoF deployable surfaces and mobility calculations for a unit, the polygonal modules, and the assemblies are computed, and motion studies are demonstrated with CAD models and exemplified for a square module for motion tests in a prototype.Article Citation - WoS: 7Review of Literature for the Concept of Post-Disaster Housing in Turkey(Gazi University, 2008) Baradan, BernaThere have been implementations of post-disaster housing even in historical ages and mentioned in studies concerning a specific period in time in which the disaster occurred in Turkey. With a brief overview of such history of post-disaster housing, the studies were reviewed based on the relationship between approaches and time periods concerning the architectural literature of post-disaster housing in Turkey between 1977 and 2005. There are mainly two types of architectural studies about this concept; observations and analyses about the general policy in Turkey, and case specific studies. These two types of studies can also classified within their writing style as well; descriptive style and analytical style of writing is used for a basis for the comparison of approaches used in the studies. The term ‘architectural literature’ used in this article were used for the works published by the architects and/or studies published in architectural magazines. From this analysis, it could be concluded that the architectural society in Turkey changed its point of view to more humanistic solutions in post-disaster housing after the 1999 Marmara Earthquake.
