Comprehensive studies are needed to discover materials and construction technologies contributing to the thermal performance of historical buildings and to keep them in working order over time. Examined in this study were the thermal performance characteristics of Şengül Hamamı, a 15th Century Ottoman bath, to discover original thermo-physical properties of historic materials and to assess thermal failures in present situation by taking into consideration recent incompatible repair work. The analyses were done by using non-destructive investigation methods, such as microclimatic monitoring, quantitative infrared thermography (QIRT), heat and water vapour transfer calculations, supported by laboratory analyses on thermo-physical properties of historic materials. The results were evaluated in terms of thermal properties of historic materials establishing the historic dome section, microclimatic characteristics of Şengül Hamamı, its original thermal characteristics, and thermal failures occurred in time due to wrong repairs. An in-situ assessment method was also developed for the identification of thermal and moisture failures at real boundary conditions by joint interpretation of QIRT and heat transfer calculation results. The study showed that historic dome structure of Şengül Hamamı was originally configured to provide sufficient thermal insulation characteristics owing to good thermal properties of its materials. That success was attributed to conscious use of low-density, high-porosity historic materials having low thermal conductance and high vapour permeability characteristics. It was seen that the thermal performance of historic structure was severely destroyed by recent repairs using concrete and cement-based materials, which were incompatible with historic fabric of the structure due to their different thermo-physical properties.

Acoustical characteristics of historical Turkish Baths Aydın, Asuman; Tavukçuoğlu, Ayşe; Department of Architecture (2008) Comprehensive studies are needed to better understand the original acoustical features of historical baths in order to uncover the historical technologies that enabled the acoustical performance for which they are renowned and to ensure they retain this performance with time. In this study, acoustic performances of Şengül Hamamı and Kadı Hamamı, two 15th century historical baths belonging to the Ottoman period, were examined to discover their original acoustical features and to assess their present situatio...
Construction techniques of four of traditional ormana houses Çelik, Gülşah; Gökce, Fuat; Restoration in Department of Architecture (2009) The subject of the thesis is construction techniques of four traditional Ormana Houses within the wider context of Akseki Region vernacular architecture. The thesis analyses the appropriate methodology and approach for a documentation of construction techniques and details of the traditional houses. As such, it includes the necessary research and analysis that would provide the base for coherent restoration principles and decisions. The thesis includes the historical background of Ormana, detailed descripti...
Environmental aesthetics of the rural architectural tradition in the Mediterranean highlander settlement: the case study of Ürünlü Kavas, Kemal Reha; Erzen, Jale Adile; Department of History of Architecture (2009) This thesis formulates a conceptual framework to account for the rural architectural traditions. The proposal is presented by referring to Ürünlü, a Mediterranean highland settlement in Southwestern Turkey. The thesis' basic assumption is the environmental coherence of the traditional rural culture. Environmental aesthetics provides the conceptual basis through which architectural elements of the environmental coherence are investigated. Environmental aesthetics enhances the inclusive conceptions of "enviro...
Spatial information systems for conservation of historic buildings case study : Doğanlar Church İzmir Günay, Serkan; Bilgin Altınöz, Ayşe Güliz; Restoration in Department of Architecture (2007) Conservation of historic buildings requires comprehensive and correct information of buildings to be analyzed in conservation decision making process in a systematic and rational approach. Geographical Information Systems (GIS) are advantageous in such cases which can be defined as computer based systems for handling geographical and spatial data. GIS have the potential to support the conservation decision making process with their storing, analyzing and monitoring capabilities. Therefore, information syste...
Value assessment for industrial heritage in Zonguldak Kılınç, Ayşem; Özgönül, Nimet; Restoration in Department of Architecture (2009) The aim of this thesis is to develop a value assessment method for industrial heritage in Zonguldak, one of the symbolic industrial cities in Turkey where mining has been the leading force since the discovery of hard coal in the mid-19th century. Values to decide what to conserve and why are searched during this process under the light of discussions on industrial heritage and values of the architectural conservation. Focusing on this aim, this study is structured in four parts as the survey on industrializ...
