The increasing influence of climate change on tangible cultural heritage in the 21st century has been recently recognized as one of the main threats to cultural heritage. Therefore, studies dwelling on the anticipated impacts of changes in the climate parameters are relatively new. This study covers the current debate on the anticipated impacts of climate change on tangible heritage. It presents a forecast on how climate change may affect physical, chemical and biological deterioration mechanisms and which traditional materials of construction may be affected and in what way. Thus, a methodological approach was proposed in an effort to guide heritage professionals in view of climate change. To this end, different databases including the inventory of the historic buildings in Turkey and the projection maps, which are the outcomes of Noah’s Ark Project and show the anticipated changes in the amplification mechanisms, were gathered by employing ArcGIS 10 software. The overlay maps were produced and evaluated from the perspective of Turkey to determine the cities, which are likely to be under the risk of different deterioration mechanisms that were anticipated to change over the century, and are rich in cultural heritage assets. After determining the case study area as Bursa, Muradiye Complex, the heritage map was produced and then the climate data series of the selected weather stations and periods were obtained. These data series were vi reclassified to make a trend analysis. Besides, heritage-climate risk maps were produced by employing ArcGIS10 software according to the selected materials and threshold combinations of temperature and relative humidity values. These maps were evaluated to understand the risk level of prevalent deterioration mechanisms. Then, archival records on the remediation processes to address defects of the buildings in the complex were gathered. The latest survey drawings of the buildings were used to calculate the surface areas of various deterioration types. Moreover, a field survey based on observations was conducted and photos were taken. At the last stage, the findings were compared with each other to interpret the prolonged defects and their relationship with climate parameters and/or inaccurate repairs. The study reveals that the historic environment in Bursa and so the cultural heritage of Turkey have been facing particular threats derived from changing climate parameters. Therefore, the aim is to provide a model to reevaluate short, medium, and long term strategies to manage the effects of these threats to render tangible heritage more resilient in the time of climate change.

A Proposal for an administrative structure for cultural heritage management in Turkey Bozkurt, Ela; Serin, Ufuk; Department of Architecture (2017) It is generally accepted that cultural heritage, a valuable, limited and non-renewable resource, is today subject to many pressures, including tourism. Globalization, rapid urbanization and the consequent development pressures, the demands and pace of modern society have all created an overwhelming appetite for new housing, which compete for the shrinking areas of urban land available, all combine to constitute an environmental threat to cultural heritage. To respond adequately to these threats, it has beco...
Rethinking cultural heritage conservation: evaluation of the treatments of former prison sites / Acar, Melih Emre; Bilgin Altınöz, Ayşe Güliz; Conservation of Cultural Heritage in Department of Architecture (2017) The prevailing mindset of heritage practice which was originated in the early 20th century, is so associated with the ‘thing’ that causes incompetence in responding to cultural and social demands of heritage conservation. Therefore, this thesis examines the treatments of former prison sites with the aim of revealing contemporary agents of cultural heritage conservation that are utilized to sustain and, indeed, to nurture intangible features of heritages. The discourse that is constructed around the abandone...
A Study for the conservation of Ertem olive-oil factory in Ayvalık / Yıldız, Gözde; Şahin Güçhan, Neriman; Conservation of Cultural Heritage in Department of Architecture (2017) Conservation and re-adaptation of industrial heritage has been a quite important aspect in the sense of continuity of the historic industrial character of the place for future generations. Industrial buildings usually lost their functions due to the fast technological developments and changing within production/consumption systems. This inevitable functional loss caused the obsolete structures which are regarded as industrial heritage. It is essential to conserve and recover the post-industrial landscapes t...
Improvement of METU-Research Laboratory for the Conservation of Historic Monuments (MONUMENTSLAB) Saltık, Emine Nevin(2011-5-31) Importance of conservation scientists and research in the care and conservation of cultural heritage has been better understood in last decades. Inadequate diagnosis, problems arising from incompatible repair materials have induced irreplaceable damage to historic structures. Adverse effects of the empirical conservation treatments or conservation treatments that were not well studied in terms of compatibility and durability have become noticeable on the monuments. There are collaborated efforts throughout ...
In-between preservation and economics: establishing common ground between socio-cultural and economic values for the sustainability of urban heritage places in Turkey Özçakır, Özgün; Bilgin Altınöz, Ayşe Güliz; Mignosa, Anna; Conservation of Cultural Heritage in Department of Architecture (2018) Conservation of cultural heritage is a ‘value’ based practice. The scholars in the fields of conservation and cultural economics have been aware of the co-existence of different values including economic as well as socio-cultural ones. Both the preservationist and economist approaches emphasize the subjectivity of ‘values’ that change according to time, context and the interests of different agents when intervention decisions about heritage places are at stake. The heritage places located at the center of c...
