Article Citation - WoS: 5Stormwater Management and Green Infrastructure Techniques for Sustainable Campus Design(Gazi Üniversitesi, 2011) Saygın, Nicel; Ulusoy, PelinThis 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.Article Citation - WoS: 2Arazi Kullanım - Ulaşım Planlaması Bütünlüğünde Uyum için Model Önerisi(TMMOB Şehir Plancıları Odası, 2018) Duvarcı, Yavuz; Alver, YalçınHer ne kadar kuramda ulaşım planlama ile arazi kullanım (nazım imar) planlama rutinlerinin birbirleriyle eşgüdüm ve uyum içinde hareket etmeleri gerektiği belirtilse de pratikte bunun pek gerçekleşemediği görülmüştür. Bu derleme çalışmasında özellikle olması gerektiği belirtilen uyumun gerçekleşememesinin ardındaki nedenler araştırılmış ve bunun nasıl sağlanabileceğine odaklanılmıştır. Sorunun kökeninde ise iki disiplinin birbirini takip eder ve benzer parametreleri paylaşır olmalarına karşın iki ayrı planlama alanı biçiminde ayrı prosedürler halinde planlamayı gerçekleştirmeye çalışmaları bulunmuştur. Ancak ideal durum olan (a) aynı anda birlikte planlamanın tek plan çalışması olarak gerçekleştirilmesi pratikte fazlaca uygulanabilir bulunmamış, yine, (b) aynı anda farklı planlama eylemleri olarak gerçekleştirilmeleri ve eş güdümlü olarak birbirlerinden beslenmeleri veri alışverişini aynı anda olanaksız kıldığından, genelde (c) ulaşım planlaması ile arazi kullanım planlamasının farklı zamanlarda birbirini takip eden ayrı planlama alanları olarak ortaya çıkması kaçınılmaz hale gelmektedir. Söz konusu ardışık ayrı (c türü) planlama eylem alanlarının temel sorunu ise birbirini karşılıklı besleyen bir döngü gibi görünse de uygulamada birbirine uyumlu gittikleri yalnızca ilkesel düzeyde kalmakta, retorikten öteye geçememektedir. Pratikte geçerli olan c türündeki uyumun sözde bir iyi niyet belirtisi olarak kalmaması ve gerçek uyumlandırmanın sağlanması için iki planlama alanının birbirini aktif olarak karşılıklı kontrol etmesi şartı aranmalıdır. Bu tür bir ilişki şemasının tesisinde, bir alanın (örneğin ulaşım planlamanın) politika hedeflerinin öteki alanın tanımlı çıktılarına (performans ölçütleri) uyumluluğu ve somut değerlerin belirlenen hedef değer aralıklarında çıkması gözetilmelidir. Bunlar somut kriterlere dönüştürülerek, modelleme çalışmalarında özellikle simülasyonlarda gözlenebilir sonuçlar üzerinden başarımları kontrol edilmelidir.Article Economic Impact of Exergy Efficient Building Block Design(IJCEAS, 2017) Mert, Yelda; Saygın, Nicel; Mert, Süha OrçunEven 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.Article Citation - WoS: 3Citation - Scopus: 4İzmir’deki Ulaştırma Projelerinin Kentsel Eğilimlere Etkileri(TMMOB İnşaat Mühendisleri Odası, 2008) Duvarcı, Yavuz; Selvi, Ömer; Günaydın, Hüsnü Murat; Gür, Güneşİzmir’deki önemli ulaştırma projelerinin kentsel eğilimlere olan etkileri Delphi yöntemi sonuçları temel alınarak analiz edilmiştir.

En etkili (olumlu/olumsuz yönde) projeler, bütünleştirilmiş raylı toplu taşıma sistemi, mevcut İzmir limanının geliştirilmesi; en fazla etkilenen sosyoekonomik eğilimler ise turizm sektöründeki gelişim, ekonomik gelişme, hava kirliliği ve özel araç kullanım oranı olarak çıkmıştır.Article Citation - WoS: 3Citation - Scopus: 5Groundwater in Local Development Strategies: Case of Izmir(IWA Publishing, 2018) Velibeyoğlu, Koray; Yazdani, Hamidreza; Baba, AlperThis study takes into account groundwater in local development strategies of Izmir, in which rapid and uneven development has occurred in recent decades. Therefore, resilience thinking is needed in the future development of the city-region. To this end, the paper aims to make an analysis of recently completed asset-based local development strategies for Izmir city towards water resiliency. The methodology has two main steps. Firstly, by using spatial interaction analysis of peninsula and river basins, potential vulnerabilities and risks are indicated. Secondly, a stratified model of strategy evaluation is conducted by scrutinizing the existing layered approaches. Then, these models were applied to all strategic decisions including water resources and indicated a high level of consistency to achieve sustainable and resilient use of blue-green infrastructure in the future of Izmir’s metropolitan area. Local assets, including water resources, are the backbone of future development of the Izmir city-region. Therefore, usage of local assets in a multi-level perspective of strategy development needs to be understood. The stratified model denotes that special emphasis should be given to different river basins in different levels. This study illustrates that synergy management is needed between different layers of local development strategies, in which the role of urban and rural households is of the utmost importance.Conference Object Citation - WoS: 17Citation - Scopus: 21Place Management of a Creative City: the Case of Izmir(Inderscience Enterprises Ltd., 2017) Mengi, Onur; Durmaz Drinkwater, Sıdıka Bahar; Öner, Aslı Ceylan; Velibeyoğlu, KorayThis study investigates how place management is used to render a creative city through the combination of soft factors as intangible characteristics and hard factors as tangible characteristics of the built environment. The study focuses on Izmir, Turkey; exploring its potential as an emerging creative city. The methodology is a descriptive analysis of recent urban design and planning activities of creative cities, reviews projects and strategies in Izmir. Findings provide a framework for place management tools and their strategic use for integration of art, design, creativity and knowledge in creative cities. Place management is used as a tool for image building and identity enhancement, and for quality of place to attract creative and knowledge workers. In the case of Izmir, hard factors triggered the formation process whereas soft factors have taken strengthen the initiative. However, both of them are yet not strong enough to creative public awareness and critical mass.Article Citation - WoS: 2Citation - Scopus: 2Exergy Analysis of Mass Housing Areas: Mavişehir I and Ii, Izmir(Inderscience Enterprises Ltd., 2015) Mert, Yelda; Saygın, NicelIn 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%.Article Citation - WoS: 17Citation - Scopus: 21An Evaluation Methodology for the Tangible and Intangible Assets of City-Regions: the 6k1c Framework(Inderscience Enterprises Ltd., 2010) Velibeyoğlu, Koray; Yiğitcanlar, TanTogether with hard and soft networks, tangible and intangible regional assets play an important role in the knowledge-based development of competing city-regions. The aim of this paper, therefore, is to investigate the best ways of managing invaluable tangible and intangible assets of city-regions. The paper explores the importance of asset management of city-regions by giving special emphasis on their knowledge asset base. This paper develops and introduces a theoretical framework to conceptualise a new approach to articulate the strategic planning mechanism, so called the 6K1C framework. The 6K1C framework is part of the strategic planning process of continuous improvement of overall public sector performance. The framework provides a proactive check-list approach integrated for managing and harnessing tangible and intangible assets of the post-industrial city-regions.Article Citation - WoS: 2Citation - Scopus: 2Soft Computing and Regression Modelling Approaches for Link-Capacity Functions(Czech Technical University in Prague, 2016) Koşun, Çağlar; Tayfur, Gökmen; Çelik, Hüseyin MuratLink-capacity functions are the relationships between the fundamental traffic variables like travel time and the flow rate. These relationships are important inputs to the capacity-restrained traffic assignment models. This study investigates the prediction of travel time as a function of several variables V/C (flow rate/capacity), retail activity, parking, number of bus stops and link type. For this purpose, the necessary data collected in Izmir, Turkey are employed by Artificial Neural Networks (ANNs) and Regression-based models of multiple linear regression (MLR) and multiple non-linear regression (MNLR). In ANNs modelling, 70% of the whole dataset is randomly selected for the training, whereas the rest is utilized in testing the model. Similarly, the same training dataset is employed in obtaining the optimal values of the coefficients of the regression-based models. Although all of the variables are used in the input vector of the models to predict the travel time, the most significant independent variables are found to be V/C and retail activity. By considering these two significant input variables, ANNs predicted the travel time with the correlation coefficient R = 0:87 while this value was almost 0.60 for the regression-based models.Article Citation - WoS: 2Citation - Scopus: 1Significance of Rent Attributes in Prediction of Earthquake Damage in Adapazari, Turkey(Czech Technical University in Prague, 2014) Tayfur, Gökmen; Bektaş, Birkan; Duvarcı, YavuzThis paper analyses rent-based determinants of earthquake damage from an urban planning perspective with the data gathered from Adapazari, Turkey, after the disaster in 1999 Eastern Marmara Earthquake (EME). The study employs linear regression, log-linear regression, and artificial neural networks (ANN) methods for cross-verification of results and for finding out the significant urban rent attribute(s) responsible for the damage. All models used are equally capable of predicting the earthquake damage and converge to similar results even if the data are limited. Of the rent variables, the physical density is proved to be especially significant in predicting earthquake damage, while the land value contributes to building resistance. Thus, urban rent can be the primary tool for planners to help reduce the fatalities in preventive planning studies.
