Doctoral Thesis Analysis of Walkability Measurement Tools (wmts)(Izmir Institute of Technology, 2019) Paykoç, Eda; Akış, Tonguç; Akış, Tonguç; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyWalking is the most basic act of human which makes all equal and liberates them in the built environment. For defining how walking friendly the area is, walkability is an issue started to be discussed from its several different aspects. Although walkability is studied from several different disciplines, it has neither accurate definition nor definite criteria.Starting from 1990s, walkability has started to be measured with hard-copy walkability measurement tools (WMTs) and followed by web-based walkability measurement tools. In the literature, WMTs are generally used as a tool to measure the walkability level of the selected case. However, there are few studies which tries to understand and examine the background process of these WMTs.The aim of this thesis is to categorize and define the background idea of walkability measurement tools by criticizing their keystones and their main ideas. The mapping, clustering, tabling and analyzing processes are the main devices to develop critical analysis. In tabulation, two specific charts are composed: Comprehensive Data Chart and Content Analysis Chart. Under Comprehensive Data Chart, properties of WMT are defined and categorized. In Content Analysis Chart, each tool’s content of WMTs are compared and criticized. Finally, the thesis developed a critical analysis for defining, comparing and understanding each and every single WMT.Doctoral Thesis Children's Perceptions of Their Urban Outdoor Experiences: the Case of Izmir(Izmir Institute of Technology, 2019) Dikmen Güleryüz, Oylum; Kasalı, Altuğ; Doğan, Fehmi; Doğan, Fehmi; Kasalı, Altuğ; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyResearch in children’s outdoor experiences is a rapidly growing field of investigation together with the increasing interest in the problems associated with rapid urbanization. Although there are studies that document positive and negative consequences of the built environment on children, children’s use of urban environments need to be investigated further in cities with fast urbanization rate where children are at a disadvantage especially given the fact that technology. The aim of this thesis is to understand through the eyes of children the intercorrelated relationship between physical characters of urban environments and the way outdoor environments are used. Therefore, a multi-site field study is conducted in five different urban zones with different physical and demographical characteristics (central, gated community, squatter settlement, mass housing and point-block settlement) in İzmir, Turkey which has high rates of urbanization and population growth. The study follows a mixed-method approach. The participants included 370 fourth grade primary school children and 258 parents. Even though the living environments selected for this dissertation vary in terms of physical qualities and demographic characteristics, 77% of children reported to prefer spend their free time outdoors. However, the study provides evidence to link children’s preferences regarding place and duration of use, and the way they use outdoor environments vary among the urban zones studied. The findings of the dissertation is linked to the growing literature on the subject with the aim to contribute to the improvement of children’s environments in cities, and the related policy-making efforts worldwide.Doctoral Thesis A Model for Assessing Acoustic Comfort in Enclosed Public Spaces(Izmir Institute of Technology, 2019) Çakır, Onurcan; İlal, Mustafa Emre; Çakır, Onurcan; İlal, Mustafa Emre; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyAcoustic comfort is one of the important topics in terms of user satisfaction. In order to determine and control acoustic comfort, measurable parameters are needed to be able to compare and improve soundscapes. Parameters for architectural acoustics, like reverberation time and sound pressure level are widely used for this purpose. Psychoacoustic parameters like loudness, sharpness, roughness and fluctuation strength are mostly used for determining the sound quality of mechanical sounds. They have also started to be used for evaluating soundscapes of open areas and enclosed spaces. This research aims to find out the relationship between the psychoacoustic parameters and acoustic comfort in non-acoustic enclosed public spaces, specifically in eating establishments. To reach this aim, both on-site measurements and in laboratory listening tests were conducted in five eating establishments. During on-site measurements, a simultaneous questionnaire study was also conducted. Subjective and objective data were comparatively evaluated. Listening tests were based on auralizations with calibrated simulation models. This provided a research model, that allows control over the acoustic environment without having to make real changes in the physical elements of the eating establishments. The auralization sound files were presented to listening test participants with headphones and they evaluated soundscapes with different psychoacoustic properties. The last chapter provides a summary of results and suggestions for future studies. Better acoustic comfort was found to be related with higher sharpness, lower reverberation time, lower loudness and lower roughness values for the examined parameter ranges.Doctoral Thesis Kinematic Design and Analysis of Deployable Vault and Pseudo-Dome Structures Based on Origami Techniques(Izmir Institute of Technology, 2017) Karaveli Kartal, Andree Sonad; Korkmaz, Koray; Korkmaz, Koray; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyIn recent years a need for more adaptable and flexible structures have been observed due to the changing spatial and functional needs. One of the solutions for an adaptable space in architecture is deployable structures. These kinds of structures provide flexible solutions to the functional and spatial necessities of an environment. There are different kinds of deployable structures such as bar and foldable plate structures, membrane, inflatable, cable/strut etc. This study presents a method of designing a pseudo-dome flat-foldable and deployable plate structure (rigid origami) based on origami patterns that have a polar rotation deployment axis. To achieve this objective, first a method of designing flat-foldable and linearly deployed barrel vault structures have been created by analyzing their geometrical properties. This analysis along with a workspace analysis provided knowledge on the geometrical relations between the cross-sections and deployment parameters. These relations allowed the design of a flat-foldable rigid origami structure based on the geometry of the cross-section using a pattern-generator. The method of using a pattern-generator to create an origami pattern has been modified to achieve a polar rotated deployable pseudo-dome structure. The design method allows the designer to calculate all the relevant parameters to create an origami structure by modifying three parameters for barrel vault foldable structures and two parameters for pseudo-dome structures. The created origami pattern is then transformed to a foldable deployable plate structure with the intended design requirements. The design processes for both design methods have been explained with case studies.Doctoral Thesis Non-Visual Aspects of Spatial Knowledge: Wayfinding Behavior of Visually Impaired People in Complex Urban Environments(İzmir Institute of Technology, 2016) Kan Kılıç, Didem; Doğan, Fehmi; Doğan, Fehmi; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyEverybody perceive space multi-dimensionally however blind people are more conscientious of the non-visual constituents of space. Although there is an extensive amount of research on mobility, perception, and way-finding of blind people, there has been fewer work to show which specific aspects of built environment they focus on and they use as cues in the way they relate to their urban environment. Therefore, this study focuses on the senses of blind individuals during their way-finding process in urban contexts. Two case studies in İzmir, Turkey and Lisbon, Portugal were conducted in large-scale urban contexts. The case study in İzmir highlights the holistic and multi-dimensional perception of space by asking 9 congenitally blind participants to mark those places that they find particularly important in Kemeralti and İzmir Fair Park by verbally describing the features in the environment they attend to. It was found that auditory information was the most used environmental cues and a feeling of enclosure is the most important environmental feature during way-finding. The second case study in Lisbon was conducted with 5 congenitally blind participants to understand the strategies of congenitally blind participants with a focus on whether sounds from the environment are of primary importance for blind individuals. The most important finding is that increased familiarity with the environment, the better way-finding strategies blind individuals have. This study highlights multi-dimensional sensory experience of urban environments and non-visual aspects of spatial perception.Doctoral Thesis Experimental and Numerical Analysis of Flow and Heat Transfer in Double Skin Facade Cavities(İzmir Institute of Technology, 2016) İnan, Tuğba; Başaran, Tahsin; Başaran, Tahsin; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyIn this study, airflow and heat transfer in a double skin facade (DSF) cavity were examined numerically and experimentally under natural and forced flow conditions. An experimental setup was constructed i the laboratory environment. Experiments were performed for two different DSF's airflow modes; buffer zone and external air channel. These experiments vere conducted with and without a solarsimulator integratrd t the system. Furthermore, the effect of pressure drop elements in the cavity of DSF were analyzed experimentally. After the numerical results (CFD and nodal network) were verified with experimental measurements, dimensionless heat transfer correlations were developed for the natural and forced convections. As a result, an extensive experimental data set was obtained for different working conditions of DSF. So, the dimensionless pressure loss coefficients were calculated experimentally based on the geometric configuration of the pressure drop elements in the cavity. In natural convection, with Rayleigh numbers ranging from 8.59*109 to 1.41*1010 and the increasing tendency of the average Nusselt numbers from 142.6 to 168.8 were shown. A correlation for a cavity characteristic length of 0.116 was constructed to evaluate the heat flux. In forced convection, another dimensionless correlations weredeveloped to predict the heat transfer by using. Nusselt numbers with in the Reynolds numbers ranging from 28000 to 56000 for a DSF with an external airflow mode. These correlations could be used for different characteristic length ranged betwen 0.1 and 0.16. These correlations were used for the energy performence of DSF applications for different directions and climatic zones in Turkey and compared with the single skin facede.Doctoral Thesis Environmental Discourse in Turkish Architecture(Izmir Institute of Technology, 2014) Yücel, Şebnem; Yücel, Şebnem; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologySince the 1960s environmental discourse has entered into architectural theory and practice in effective ways, inducing disciplinary transitions in all three categories: artefacts, knowledge and practices. This dissertation emphasizes the discursive character of this “environmental turn” in architecture and aims to make explicit its significance for Turkey. To that end, the dissertation reviews four Turkish architectural periodicals covering a time span of 49 years from 1963 to 2012. The data is then used for tracing of the formation of the discourse on environmental architecture in Turkey by illustrating how certain concepts and themes arose at specific time periods and their transformations in time. In that context, the dissertation emphasizes three concepts – environment, sustainability and energy-efficiency- and in revisiting these in a sequential and overlapping fashion a general outlook of the conditions in which the discourse on environmental architecture have emerged is sketched. Such an analysis reveals the transformation of environmental considerations from that of radical reflections to legitimate concerns in Turkey. Yet, it also displays that this “legitimation” is based on an unquestioned “givenness” of the objects and statements of the discourse. This, in return, creates a speculative basis of legitimacy removing it from its social and economic contexts. This study has taken on this challenge by emphasizing the system of formulating the problems –namely the “problematic” of the discourse as its main concern. In that context, it first of all presents the analysis of the mechanisms in which environment has risen as an important problem of architecture in Turkey, and secondly, reveals the relations of this process to the nature of solutions proposed. In the end, by emphasizing the taken-for-granted assumptions and generalizations inherent in the discourse on environmental architecture in Turkey, the dissertation aims to open up for new avenues in which new formulization of the problems could emerge.Doctoral Thesis An Evaluation Methodology for Assessing Artificial Lighting Quality in Architecture: the Case of Apikam(Izmir Institute of Technology, 2007) Kutlu, Hilmi Gökhan; Günaydın, Hüsnü Murat; Günaydın, Hüsnü Murat; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyThe aim of this dissertation is to design a qualitative evaluation methodology for artificial lighting. There is a problem in the general characteristics of lighting industry, deriving from its technical vocabulary which is mainly based on quantitative parameters, values, and systems which in some ways are neglecting the main ingredient of architecture: the user. The evaluation methodology that is subject of this dissertation was considered as a qualitative approach to lighting quality. The study benefited from the knowledge of environmental psychology, concerning the effect of lighting on behaviors and tried to integrate it to the process of assessing lighting quality. The methodology depends on data collection by various means such as surveys, measurements, and computer simulations. To test the qualitative evaluation methodology, a case study was designed in the exhibition hall of the Ahmet Piritina City Archive and Museum (APIKAM) in zmir. The evaluation methodology was successfully operated and made a detailed evaluation possible on the two lighting systems in the exhibition hall of APIKAM. Both lighting systems failed in functional aspects, because of the high intensity of light they produce, the emission of UV and IR wavelengths, and glare problems. They are simply not appropriate for the selected environment, where organic . based materials are exhibited. Recessed fluorescent lighting system failed in physiological aspects as it triggers less arousal than halogen spotlighting system. Both lighting systems have failed in attention scale under psychological aspects, because none of them supply continuity in the order of visual clues that match with the sequential order of the exhibition. For aesthetic and environmental judgments, the results of the survey showed that halogen lighting system was the preferred one by the subjects. For the sub-part of feelings, recessed fluorescent lighting systems failed, because it influenced generally negative feelings, while positive feelings are generally influenced by halogen spotlighting system.Doctoral Thesis A Model for Assesing Project Management Maturity Level of Architectural Design Offices (arch-Pmm)(Izmir Institute of Technology, 2007) Beset, Doğan Arda; Günaydın, Hüsnü Murat; Günaydın, Hüsnü Murat; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyThe aim of this dissertation is to develop a model to assess .The Project Management Maturity Level of an Architectural Design Office. (Arch-PMM). The purpose of ARCH-PMM is to develop an environment for productive and efficient design conditions. By increasing the levels of ARCH-PMM, architectural design office will create opportunity to focus on its concerns for high quality architectural design process. To determine whether Arch-PMM assessment methodology is working properly, a semi structured survey is conducted with selected architectural design offices. This study is the first attempt that focuses on architectural design offices. PM practices and processes. A 5 leveled PM Maturity Model is developed to assess architectural design offices. current PM Maturity level. Maturity levels are assessed vis a semi-structured survey. 71 Members of the Association of Turkish Independent Architects (ATIA)participated to semi-structured survey to validate the model. A list of demographical questions was asked to draw the demographical picture of the architectural design offices. Both, maturity levels and demographical data are analyzed. The results of the assessment provide the necessary information for the architects to improve their PM processes and activities. Project Integration Management was highly mature among the other function areas and it.s followed by Project Scope Management. The least matured function area was the Project Risk Management. High correlation values between the number of staff and all PM function areas are also observed. Yearly income level and overall maturity level of the architectural design offices are found to be related at correlation high levels (r.0.73). The well defined structure of architectural design process seems to support project management culture and have potentials of high project management maturity levels.Doctoral Thesis A Critical View of Sustainable Architecture in Turkey: a Proposal for the Municipality of Seyrek(Izmir Institute of Technology, 2003) Durmuş Arsan, Zeynep; Durmuş Arsan, Zeynep; Erdoğdu Erkarslan, Özlem; Erkarslan, Özlem; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyThis dissertation aims at developing a sustainable design process prioritizing locality in social, cultural, ecological, political, economic, technological, legalistic,and architectural terms. To this end, it aims first of all at developing an approach for elimination of misconceptions.primarily informed by technological, morphological and numerical indicators.about what constitutes the concept of sustainability in architectural practice today and therefore starts out from a critical historical overview of approaches and practices for sustainability in the world and in Turkey. The thesis undertakes the critique of sterile projects in sterile environments and calibrates the replicable and exemplary aspects of international and national sustainable design practices so as to introduce, promote and guide realistic, practicable, and case-specific sustainable architectural solutions. The specific focus in both the critical evaluation of extant sustainable practices abroad and the proposed process for the municipality of Seyrek in Menemen, Izmir, Turkey, is the distinction between the assets and needs of industrialized northern geographies and southern geographies which are in the process of industrialization and which are frequently misguided by economic exigencies imposed by the industrialized north. As a village located in an Important Bird Area, in the vicinity of a Ramsar Site and on the edge of a First-Degree Natural Conservation Area, the case area in question provides a trenchant example for the study of the meaning of sustainability in a southern socio-politico-economic zone and a challenge for the architectural designer. Seyrek is a mirror of global as well as local problems today. It is located in the middle of Gediz Delta, the large agricultural land as well, and on the edge of several specialized industrial districts of the urban sprawl of Izmir.Placing the analysis of the case area in the context of the wider framework of international policy, the thesis proceeds to propose specific design tools for a sustainable housing development project in a crucial typical new residential segment of the semi-rural settlement of Seyrek.
