    Energetic and Exergetic Design Evaluations of a Building Block Based on a Hybrid Solar Envelope Method
    (Springer Verlag, 2018) Mert, Yelda; Saygın, Nicel
    To achieve sustainable development, there needs to be a focus on decreasing use of non-renewable energy sources and greenhouse gas emissions. In this regard, many studies focus on the strong relationship between energy and the environment. This study aimed to introduce the exergy analysis method into the urban planning field to find out the amount of exergy, rather than energy, that can be conserved in a building block when a solar envelope-based design is applied. In addition to the known energy-efficient design parameters, a criterion for the solar envelop method is integrated into a single method. This hybrid method includes taking into account the requirements for orientation, spacing, landscaping, and building form, as well as the building height properties as proposed in the solar envelop method. The solar envelop method depends on understanding the changing position of the sun throughout the day and year. If this dynamic behavior can be a factor in the design of an urban area, environmental friendliness, sustainability, and reduced energy consumption can comprehensively be achieved in cities.

    Energy Efficient Building Block Design: an Exergy Perspective
    (Elsevier Ltd., 2016) Mert, Yelda; Saygın, Nicel
    This study introduces the exergy analysis method into the field of urban planning, in order to find out the amount of energy that can be conserved in a building block when an energy efficient construction design is applied. This was done in four steps. First, energy efficient design parameters were derived from the literature and design alternatives were developed accordingly. Second, data was gathered from the case area for the exergy calculations. Third, exergy analysis of existing building blocks and proposed design alternatives were separately carried out. Finally, the amount of decrease in the exergy loss due to suggested energy efficient design was found out. The results show that the exergy efficiency of the existing building blocks is about 2%, while the proposed design alternatives will be around 10-11%. The overall exergy loads of the alternative plans were found as 166.3 W, 225.1 W, 142.5 W and 137.8 W respectively for winter and 105.4 W, 140.0 W, 89.9 W and 86.3 W respectively for summer, on a housing unit basis. As a result, the suitability and importance of the exergy analysis on the built environment was proven, by revealing actual and considerable energy conservation and sustainable use of energy through application of energy efficient design parameters.

    Evaluation of the Conservation Activities in the Historical Settlement Tenedos-Bozcaada Island
    (WITPress, 2011) Akpınar, Figen; Saygın, Nicel; Karakaya, Emel
    The efforts for the conservation of cultural heritage in historical settlements are a highly problematic and multi-faceted issue in Turkey. Although the conservation legislation dates back 50 years, the cultural heritage has not been internalized and not accepted in wider parts of the society and, has not found a solid political base. The historical and cultural heritage areas are mostly marketed for tourism and turned into places as the simulacrum of the elitist and middle class tastes. Tenedos (Bozcaada) Island inherits the rich cultural heritage of two millennia. The Island is in danger of losing its social, cultural and multi-ethnical characteristic where Turkish and Greek societies live harmoniously. The architectural, economic and ecological values are also in danger because of the rise of touristic activities and the construction of vacation homes as well as the State's withdrawal to provide subsidy to the agricultural sector that took place after the 1980s in parallel with the general economic policies adopting global economic restructuring. The objective of the paper is to highlight the multidimensional character of the social and spatial process which is enmeshed in the conservation activities of the Island. The values and norms, social, economic considerations in the conservation activities need a new approach and, without existence of a common will and a wider participation of the society it is hard to expect any success in the conservation of the rich cultural values, and to assess, develop and carry them into the future. A bundle of techniques are used: a large survey analysis of the area is realized and its social, historical and physical characteristics are documented. Questionnaires, in-depth interviews are used in order to detect the difficulties for conservation of the heritage in part of the responsible public bodies. The public and tourism sector opinions, thoughts and aspirations are surveyed. Even though, the preservation of Tenedos Island's cultural heritage appears to be a difficult challenge, there seems to be some positive clues for the future. © 2011 WIT Press.

    Reclaiming Ecological Sustainability of Urban Streams by Use of Green Infrastructure Techniques
    (Izmir Institute of Technology, 2016) Aksoy, Selçuk; Saygın, Nicel
    Ecological sustainability of urban streams has been significantly reversed from the last quarter of the 20th century onwards. This reverse has occurred as a result of increasing urbanisation and human activity, including construction in floodplain areas, relocation and culverting of streams, channelization, riparian clear-cut, and discharge of wastewater into streams. However, on comprehending the significance of urban streams, ecologically-based stream rehabilitation projects have been preferred to hard engineering solutions. These rehabilitation projects not only restore stream ecosystems but also reclaim their contribution to urban landscapes through the provision of ecological, social, and cultural assets. Based on the above, this study sets out to examine urban stream rehabilitation in the context of sustainable water management. In that regard, this research suggests an integrated and holistic approach through green infrastructure tools which can compensate for misguided human interventions on nature, and reclaim ecological sustainability of urban streams and their environs. In line with ecological sustainability, best practices from various countries and the case study of the research evidenced how the degraded stream ecosystem could be rehabilitated by using green infrastructure techniques. The research methodology used in the study involves analysis of the theoretical literature on green infrastructure and stream rehabilitation, best practice analysis, and case study analysis to develop a rehabilitation guideline for Arap Stream and its surroundings. In this sense, the research presents urban-scale, district-scale and neighbourhood-scale rehabilitation strategies for the case study. Finally, the study delivers the rehabilitation plan for Arap Stream that includes in-stream and green infrastructure techniques.

    Place-Making: Examination of Practices in Turkey
    (Izmir Institute of Technology, 2015) Kuru, Ömür Damla; Saygın, Nicel
    Place-making is an approach which represents a comprehensive framework in building public places with a major concern of assigning functions in an ongoing process. The major point that place-making distinguishes from the former approaches is underlining the process of making instead of the certain product of design. This thesis is a descriptive study which aims to explain the making process of contemporary practice in Turkey. The perceptions of privacy and publicness concepts in Turkish Culture are different than they are in Western Culture. These two cultures are similarly affected by recent movements against top-down policies which lead commodification of commons. Pressures cause reactions such as Wall Street Occupation and Occupation of Tahrir Square. When we consider Turkey, we see that the place-making process is driven by NGOs and platforms that advocate right to the city similar to worldwide movements. In this thesis place-making process in Turkey is introduced with its traditional background and its contemporary break through. Three types of bottom-up movements are taken as cases that are selected from Istanbul, the primary city of Turkey and under a great pressure of construction. Gezi Park Occupation, Kuzguncuk Farm Reaction and Don Quixote House Occupation and Yeldeğirmeni Neighborhood Revitalization are analyzed through main components of making process; actors, processes and outcomes. It is remarked that place-making process draws a distinct identity rather than the traditional approach to public places and aims to protect commons by advocating right to the city in different social contexts that reflect the complexity of place-making process.

    Application of Exergy Analysis Method To Energy Efficient Building Block Design
    (Izmir Institute of Technology, 2014) Mert, Yelda; Saygın, Nicel; Saygın, Nicel
    This dissertation introduces the exergy analysis method into urban planning field in order to find out the amount of energy that can be conserved in a building block when energy efficient design is applied. Two hypotheses are developed here: 1. Exergy analysis is a suitable tool for the built environment, and 2. Energy efficient design parameters provide energy saving in the built environment. A case study approach is undertaken in order to test the hypotheses stated above. To do this, first, the energy efficient design parameters have been derived from the literature and design alternatives are developed accordingly; second, data has been gathered from the case area for the exergy calculations; third, exergy analysis of existing building blocks and proposed design alternatives are carried out, and finally, the amount of decrease in the exergy loss due to energy efficient design is found out. The findings in this study show that the exergy efficiency of the existing building blocks is nearly 2 %, while the proposed design alternatives are nearly 10-11 %. The overall exergy loads of the alternative plans are found as 166.3W, 225.1W, 142.5W, 137.8W and 184.8W respectively for winter and 105.4W, 140.0W, 89.9W, 86.3W and 125.3W respectively for summer on a housing unit basis. These results are much better when compared to the existing situation per housing unit which is 1079W (winter) and 1173W (summer). The best alternative energy efficient planning and design brings 1631 W (winter) and 2810W (summer) of exergy saving that corresponds to 799 TL/year and 978 kg/year reduction in CO2 greenhouse gases emission per housing unit. This data shows that the expected results and are in harmony with the literature. As a result, the suitability and importance of the exergy analysis on the built environment is proved by revealing the energy conservation and sustainable use of energy through using energy efficient design parameters.

    The Development of Shopping Centers in Turkey: The Case of Denizli
    (Izmir Institute of Technology, 2010) Kuyumcu, Aysun; Saygın, Nicel
    In the last decade, even though the importance of shopping centers appear to decrease day by day, their place within the Turkish real estate market displays a considerable rise. Among those reasons underlying the increase of investments on shopping malls take place the stability of the economic environment, the insufficiency of supply within the market of shopping centers, the young and dynamic population, the increase on gross domestic product, and the high profit ratio compared to other countries. As an explanatory research, this study targets at evaluating the changes and development of shopping centers in history, identifying the characteristics of today's shopping centers, examining the location criteria of shopping centers, and focusing on the development of shopping centers from the world-wide scale to Turkey and Denizli. This study has dwelled upon the characteristics and classification of shopping centers in the world by ICSC and DeLisle and of those in Turkey by AMPD. Among the examined issues take place the adopted criteria in selection of location for shopping centers and the development process of Turkish shopping centers as based on quantitative information obtained. The development process of shopping centers in Turkey have been analyzed for the period between 1988-2009 and in addition to existing circumstances, future considerations have also been made. Examination of the development process of shopping centers in Denizli, on the other hand, has involved consideration of firstly the geographical and socio-economic status of the city, and then of the urban development profile as well as the traditional trade district. In the final stage of the examination, all shopping centers in Denizli have been chronologically analyzed in terms of their development processes, investors, relations with the urban pattern, physical characteristics, transportation facilities and accessibility. In result of the comparative evaluation, discussions focus mainly on the location of shopping centers and their harmony with the urban pattern as well as their future strategies against the threat of becoming identical with one another.

    Sustainable Management of Water Resources on Campus: the Case of Izmir Institute of Technology
    (Izmir Institute of Technology, 2011) Ulusoy, Pelin; Saygın, Nicel; Saygın, Nicel
    The concept of sustainability plays an essential role in university campus development. This study specifically focuses on sustainable water resources management among extensive sustainable campus principles. Water is a non-renewable asset for our increasingly arid geography due to reasons such as global warming. The sustainable management of water resources includes capture and reclamation of rainwater/stormwater, treatment of wastewater, protection and enhancement of groundwater quality, protection and rehabilitation of natural water bodies (creeks, streams, rivers, lakes and others) and efficient landscapes. Green infrastructure techniques prevent runoff problems due to conventional drainage such as flood and water quality degradation; and provide natural drainage and infiltration, improve water quality, prevent floods and enhance ground water. In thisstudy rainwater/stormwater is treated as a non-renewable resource instead of wastewater. This water resource can be captured and reused for different purposes such as irrigation, groundwater recharge, green corridors and landscape amenity by integration of rainwater/stormwater features into the site in an aesthetically pleasing way. Additionally, use of green infrastructure techniques reduces the consumption of clean water. This study develops strategies for use of green infrastructure techniques and recommendations to guide the implementation of these strategies. As a case study, recommendation of green infrastructure techniques with efficient landscape for entire Izmir Institute of Technology (IYTE) Campus located in Gülbahce-Urla (Izmir) has been developed.
