    Stormwater Management and Green Infrastructure Techniques for Sustainable Campus Design
    (Gazi Üniversitesi, 2011) Saygın, Nicel; Ulusoy, Pelin
    This study focuses on sustainable water resources management among extensive sustainable campus design principles. Water is a non-renewable asset for our increasingly arid geography due to reasons such as global warming. The sustainable approach to water resources consists of reclamation and capture of rainwater/stormwater, treatment and reuse of wastewater, protection and enhancement of groundwater quality and natural water bodies (creeks, streams, rivers, lakes and others) and creating water-efficient landscapes. Green infrastructure systems provide natural drainage and infiltration, prevent floods, improve water quality, and enhance ground water. In this study 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 design. This study develops strategies for use of green infrastructure systems and recommendations to guide the implementation of these strategies. As a case study, first the current state of stormwater sustainability at Izmir Institute of Technology (IYTE) Campus, located in Gulbahce-Urla (Izmir), is discussed. Then, to improve and sustain the hydrologic balance, green infrastructure best management practices (BMPs) for IYTE School of Architecture grounds are developed as a pilot study of an ongoing masters thesis.

    Economic Impact of Exergy Efficient Building Block Design
    (IJCEAS, 2017) Mert, Yelda; Saygın, Nicel; Mert, Süha Orçun
    Even after the end of 20th century, the details of connection between energy especially energy production-and the environment were not fully understood. The population growth in last thirty years, undeniable climate changes and the starvation of non-renewable energy source reserves leaves no room for doubt, however: energy and environment share a strong and significant connection. This perspective is especially important in the world of economics, considering the cost of energy for end users. This study covers the economic impact and gain of applying exergy efficient planning to a building block. The study hereby undertakes a case study to show that an efficient planning can help save energy, and thus money. The existing blocks of the chosen case had 2% energy efficiency, while the designs proposed in the study have 10-11%. The findings in this study show that an 8 % improvement in the exergy efficiency of the building block results in 780.05TL saving for a single housing. This sums up to 54.603,49TL for the building block annually.

    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.

    Exergy Analysis of Mass Housing Areas: Mavişehir I and Ii, Izmir
    (Inderscience Enterprises Ltd., 2015) Mert, Yelda; Saygın, Nicel
    In this study, in terms of urban design, an exergy analysis of Mavişehir mass housing area in Izmir, Turkey is carried out based on spatial properties, shadow effects, wind effects and local climate to understand the importance of design strategies. The exergy analysis is applied with broad consideration covering the heat loads of the separate buildings for winter and summer. When the exergy results of Mavişehir I and Mavişehir II are compared it is found that Mavişehir II has less exergy by fuel and exergy load values. This may result from different design strategies in Mavişehir I where the same buildings and villas between residential buildings are located according to sea view, whereas in Mavişehir II, there is a heterogeneous pattern with various forms and heights of the residential buildings. It was also discovered that exergy efficiency of the area is 4.20% and the exergy flexibility factor is 19.3%.

    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.
