The realization of net-zero exergy districts can be supported by urbanization options for district density and building characteristics. This research work formulates an urbanization algorithm to minimize the carbon dioxide emissions responsibility of districts based on energy usage and aspects of embodied energy to tackle multiple drivers of urban emissions. The combined method is implemented to scenarios that contribute to a net-zero exergy district target with 6 options for district density and the selection of building materials. Based on a comparison of scenarios for a case study in the province of Ankara, Turkey, the scenario in which on-site exergy production is about 9.5% of the annual exergy consumption will be responsible for about 13,731 ktonnes of carbon dioxide emissions in a timeframe of 30 years. Conversely, a near net-zero exergy district in which on-site exergy production is 75% of the annual exergy consumption will have about 2967 ktonnes of carbon dioxide emissions during the same timeframe, including embodied energy in buildings. The sensitivity analysis with 9 different combinations provides differences in trade-offs based on timeframes and scenarios. The research work has ramifications for local decision-making to avoid locking-in of carbon dioxide emissions by prioritizing an integrated approach to urban energy solutions on the supply and demand sides, district density, and building materials while reaching net-zero targets in the future.

The transformation of urban space at the conjunction of the old and new districts : the city of Aleppo
Miroğlu, Ebru Aras; Sargın, Güven Arif; Urban Design in City and Regional Planning Department (2005)
The urban space is subjected to countless transformations depending on multiple reasons such as urban planning decisions, the administrative system and regulations. In this context, the aim of this thesis is to reveal the spatial transformation of an urban area at the conjunction of the old and new districts of a historical city. A morphological analysis method depending on quantitative and qualitative chaarcteristics will be utilized to understand its changing spatiality.
Employing remote sensing technique to monitor the influence of newly established universities in creating an urban development process on the respective cities
Cetin, Mehmet; Aksoy, Talha; Cabuk, Saye Nihan; Şenyel Kürkçüoğlu, Müzeyyen Anıl; Cabuk, Alper (2021-10-01)
Universities have a wide range of effects on the development of the cities, economic growth and socio-cultural structures of the communities. Accordingly, the Turkish government has encouraged the establishment of the higher education institutions to support the regional development especially in the underdeveloped areas. In this study, 13 universities established after 2006 in the eastern and south-eastern regions of the country were analysed for the determination of the effects of the university establish...
Analysis of urban morphology in squatter transformation areas
Şahin, Mustafa Raşit; Yetişkul Şenbil, Emine; Department of City and Regional Planning (2014)
The impacts and results of urban transformation has been discussed as an important issue in developing countries by different disciplines as political economy, urban design, city planning and urban sociology. Urban transformation projects in Turkey are mainly criticized since the main focus is about physical transformation. In this context, the aim of the study is to determine what quality of space is produced by urban transformation projects in Turkey. Urban transformation projects creates a different scal...
A Critical evaluation of the urban transformation in Çukurambar, since the late 1980s
Ajazi, Gerta; Sargın, Güven Arif; Meij, Agnes van der; Department of Architecture (2015)
The primary purpose of this study is to put forward a critical examination on the urban transformation of Çukurambar district in the last three decades, under the forces of changing political, administrative, economic and social structure of the city. The fragmented structure of the neighborhood which resulted from the insufficient policies regarding the planning procedures in Turkey, is an inevitable problem which should be dealt with and the urban renewal plans prepared for Çukurambar should be investigat...
The role of urban agriculture in sustainable urban development, creation of social bonds and community formation
Erişen, Yağmur; Akkar Ercan, Zübeyde Müge; Urban Design in City and Regional Planning Department (2022-4-18)
With the ever-increasing urbanization, sustainable urban development has gained more importance. Actions to achieve sustainable urban development have been discussed from many perspectives. One of the prescribed actions for successful sustainable development is the sustainable communities according to the specific urban context, responding to the wants, needs and the culture of its community. With the COVID-19, people in cities realized the importance of green spaces and the critical need for socialization....
