In developing countries such as Turkey, the main driving force of economy is the Architecture-Engineering-Construction (AEC) industry. Hence, rapid urban expansion dramatically increases the pressure on the existing infrastructure which affects buildings, public transportation and overall energy usage. In order to control urbanization, governments facilitate mass-housing projects in increasing numbers. Higher rates in construction require an immediate need for methods of assessing the environmental impacts of these large scale mass-housing projects. Currently, there is not any framework or legislation which regulates the environmental impact of mass-housing projects. In order to provide a comprehensive response to this need, the study aims to develop a life cycle assessment (LCA) based decision support tool (DST) for early design phase of mass-housing projects in Turkey. DST should take into account several clusters of aspects that are inherit in the urban and typological characteristics. In this context, neighbourhood scale is considered as the suitable scale in order to have more precise results. This tool is aimed to provide planners with decision support where and when it is most needed. Residential buildings are the most constructed building type in Turkey, and early design phase is when the design preferences have the highest impact. In the end of the assessments, a reference LCA study which represents the mass-housing projects in neighbourhood-scale in Turkey was developed. Different embodied carbon values were defined for project typologies. Depending on the reference LCA study, a decision support tool (DST) for mass-housing projects in neighbourhood scale was achieved. The DST is capable of introducing several sustainable solutions that are appropriate for mass-housing projects.

The Use and efficiency of housing stock in Turkey Oğuz, Saygın Can; Balamir, Murat; Department of City and Regional Planning (2003) Although efficient use of stock is an important issue of housing economics and policies, there is very little research on the subject in Turkey. This study aims to investigate the stock efficiency in Turkey by measuring the degree to which the housing stock matches household size. Distributions between dwelling units and the households in terms of their size are investigated for this purpose. The stock is studied within three zones of occupational density: أcomfort, overcrowding and underoccupationؤ, accord...
A robust green traffic-based routing problem for perishable products distribution Tirkolaee, Erfan Babaee; Hadian, Shaghayegh; Weber, Gerhard Wilhelm; Mahdavi, Iraj (Wiley, 2020-02-01) Nowadays, transportation and logistics are considered as the drivers of economic development in the countries due to their impacts on the main variables of the country's economy such as production, employment, price, and the cost of living. Statistics indicate that fuel consumption constructs a major part of transportation costs, where its optimization leads to the creation of an energy-efficient and sustainable transportation system. On the other hand, vehicles' traffic is also one of the main criteria aff...
A Study on the price escalation system in public construction contracts in Turkey Ercan, Muhammed; Dikmen Toker, İrem; Birgönül, Mustafa Talat; Department of Civil Engineering (2017) The construction industry has a major role in the development of Turkish economy. The construction sector contributes 6-8 % of the gross domestic product of Turkey. At the same time, public investments comprise an important portion in the Turkish construction sector. Medium to large construction projects generally take over a year for completion and cost of materials and labor that are used as resources in construction projects often increase during implementation of construction projects. On the other hand...
A comparative study of classical and machine learning approaches for time series forecasting: an empirical analysis on exports in Turkey Günel, Eda; Yozgatlıgil, Ceylan; Department of Statistics (2019) Exports has become one of the main economic indicator for countries. Accordingly, an accurate forecasting for exports is an important step for decision making and finding the most appropriate forecasting model constitutes the main subject of many studies. By taking the popularity and success of the machine learning (ML) methods on time series forecasting tasks into consideration, they are utilized also in this study to observe their predictive performances on Turkish exports. In this respect, Long Short Ter...
Building Marshall Plan in Turkey: the formation of workers’ housing question, 1946-1962 Karataş Başoğlu, Sıla; Cengizkan, Ali; Department of Architecture (2015) This thesis aims to analyze the formation of workers’ housing question at manpower, topographical, morphological and habitual scales with regard to the ideological, political, economical, cultural and institutional programming of Americanization in Turkey within the scope of the financial and technical assistance programs of the Marshall Plan accompanied by the praxis of the United Nations. Based on the premise that the Marshall Plan engaged in workers’ housing production and architecture culture in Turkey ...
