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.Master Thesis The Metaphor of "curtain Wall" in the Modern Architectural Discourse(Izmir Institute of Technology, 2013) Kutluay, Pınar; Yücel, Şebnem; Yücel, Şebnem; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of Technology"Curtain wall" is mostly regarded as a direct outcome of the industrial reform in the Nineteenth Century. Following technological determinist approach, most of the studies about curtain wall seek to find an origin for it in the late Nineteenth Century. Different from these studies, this thesis investigates the formation of the discourse of curtain wall in view of its metaphoric background. Instead of focusing only on technology as the main factor, the study unveils different sides of the discourse which remained in the background and deciphers how "curtain," a term borrowed from textile and theatre, has been associated with facade of frame structure. In detail, the study sheds light on how frame structure, one of the main components of a curtain wall system, came to be called as "skeleton" with reference to the theory of organicism. The dressing --Bekleidung-- theory of Gottfried Semper is also examined as an alternative interpretation of the relationship between structure and facade regarding monumentalization through dressing and masking; as skeleton structure led architects to reconsider wall with concern of representation. Furthermore, the study concentrates on the architectural environment of Chicago in the second half of the Nineteenth Century, exploring two mainly different interpretations of frame structure which both arose from a shared concern of representation by some significant architects, including Louis H. Sullivan, who was also interested in monumentalization through ornament. This thesis claims that curtain wall is a metaphor invented to reconcile the emerging technology with the theory of representation which had diverse sides.Doctoral Thesis Effect of Urban Geometry on Pedestrian Level Wind Velocity(İzmir Institute of Technology, 2011) Yücel, Şebnem; Yücel, Şebnem; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyIn the recent years there are many studies on the detection of the Urban Heat Island (UHI) Effect which shows itself mostly by the temperature difference between rural and urban areas. The heat generation in the city, the radiant energy balance, the air flow direction and intensity are the main factors affecting the UHI. Height and shape of the buildings, the street width and orientation, the space between the buildings and the urban topography and vegetation are the main elements of the urban geometry. The air velocity is either increased or decreased by building blocks and the solar energy is trapped in the urban canyons formed by buildings on both sides of the streets. Pedestrian comfort level is greatly affected by the temperature, the relative humidity and the wind speed in urban canyons. The city of Izmir has been experiencing very hot summers especially in the recent years due to the UHI effect and the global warming. The compact organization of the streets in the mild climate of Izmir during the winter protects pedestrians and building façades from cold winds. However the prevailing wind and the local breeze in the summer season on the coastal region in Izmir are blocked by the buildings as well, causing discomfort during the hot summer days. Although this is a well known problem in Izmir, there are very few scientific studies on the subject to bring it above a speculative level. The aim of this study is to fill this gap as much as possible and find a way to create guidelines for planners and architects for future plans or physical organisation of the city and making strategies for better urban environment and comfort conditions for the citizens of Izmir.
