    Process-Centered Modeling Experience From Architect's Perspective: a Case Study in a Residential Building in Izmir
    (Izmir Institute of Technology, 2019) Gülmez Raafat, Rahşan Aytül; Durmuş Arsan, Zeynep
    Predicting current energy demand and future energy consumption of buildings is the challenging experience for architects. Although there are various dynamic simulation tools that enable them to calculate building energy performance, the complexity of tools poses problems to model, understand process-centered simulation studies and interpret the results. This thesis aims to present, test, verify and criticize the modeling, simulation and calibration processes of residential building from architect's perspective. One of the effective ways to overcome global warming problem is by immediate involvement of architects into energy modeling process. Therefore, the study criticizes the role of architect in process-centered modeling. Process-centered modeling is tested with existing residential building conditioned with air-source heat pump in İzmir-Turkey. Indoor and outdoor environment were monitored from July 2009 to June 2010. Digital model of the building was created by using DesignBuilder dynamic modelling tool, and calibrated for three different periods of heating, cooling and transition. The problems faced during modeling and simulation based on professional knowledge of the architect and simulation tool was exemplified. Finally, the survey was conducted to verify the role of architect tool users in modeling process. Consequently, case study exemplified how the architect conducts a processcentered modeling, and survey showed how his/her modelling experience and knowledge is essential for right management of design process. Mechanical systems modeling is still challenging issue requiring knowledge and experience for architect users..

    An Approach for Developing Sensitive Design Parameter Guidelines To Reduce the Energy Requirements of Low-Rise Apartment Buildings
    (Elsevier Ltd., 2012) Yıldız, Yusuf; Korkmaz, Koray; Göksal Özbalta, Türkan; Durmuş Arsan, Zeynep
    High levels of energy consumption in residential buildings and global warming are important issues. Thus the energy performance of buildings should be improved in the early stages of design. This article describes an approach for developing guidelines on sensitive and robust design parameters for the present, the 2020s, the 2050s and the 2080s. Such guidelines can help architects to design low-rise apartment buildings that require less energy for various purposes, such as heating or cooling. The article consists of a general literature review, interviews with architects, the generation of case-specific information and a mock-up presentation and a meeting with professionals. An example guideline that aims to reduce annual cooling energy loads under global warming in low-rise apartment buildings located in hot-humid climates is presented to demonstrate how the proposed approach can be applied. For this guideline, case-specific information was generated, and a global sensitivity analysis based on Monte Carlo Analysis and the Latin Hypercube Sampling technique was performed. The results show that the suggested approach is feasible and could be used to provide helpful information to architects during the design of low-rise apartment buildings with high energy performance. The most sensitive design parameters that affect annual cooling energy loads in low-rise apartment buildings were natural ventilation, window area, and the solar heat-gain coefficient (SHGC) of the glazing. The results are relevant for the present, the 2020s, the 2050s and the 2080s.

    Identification of the Building Parameters That Influence Heating and Cooling Energy Loads for Apartment Buildings in Hot-Humid Climates
    (Elsevier Ltd., 2011) Yıldız, Yusuf; Durmuş Arsan, Zeynep
    Identifying the building parameters that significantly impact energy performance is an important step for enabling the reduction of the heating and cooling energy loads of apartment buildings in the design stage. Implementing passive design techniques for these buildings is not a simple task in most dense cities; their energy performance usually depends on uncertainties in the local climate and many building parameters, such as window size, zone height, and features of materials. For this paper, a sensitivity analysis was performed to determine the most significant parameters for buildings in hot-humid climates by considering the design of an existing apartment building in Izmir, Turkey. The Monte Carlo method is selected for sensitivity and uncertainty analyses with the Latin hypercube sampling (LHC) technique. The results show that the sensitivity of parameters in apartment buildings varies based on the purpose of the energy loads and locations in the building, such as the ground, intermediate, and top floors. In addition, the total window area, the heat transfer coefficient (U) and the solar heat gain coefficient (SHGC) of the glazing based on the orientation have the most considerable influence on the energy performance of apartment buildings in hot-humid climates.

    Energy and Environmental Performance Based Decision Support Process for Early Design Stage of Residential Buildings
    (İzmir Institute of Technology, 2016) Gerçek, Mümine; Durmuş Arsan, Zeynep
    Deficiencies in systematic approaches for design decision support to increase energy and environmental performance of buildings in Turkey are projected as the major problem of this study. Rare usage of computational methods for evaluating and improving building performance, need for informational assistance in design, as well as lack of interaction between systematic knowledge and building practice are the secondary problems. This thesis mainly aims to test usability of the decision support process assisting architects in early design stages of residential buildings. Assessing the uncertainties in building performance caused by design parameters and climate change, in terms of determining the most significant parameters on annual energy consumption for heating, cooling and operational CO2 emissions in hot humid climatic region of Turkey is the significant objective of the study. The relation between input parameters and building performance indicators is examined by the uncertainty and global sensitivity analyses for a residential building in İzmir, Turkey. The process is supported by usability testing held with the architect in practice. The results indicate that, the sensitivity between input and output parameters changes according to the projected weather conditions and different floors of the building. The SHGC of windows on south-west, north-east facades, and window U values are the most effective parameters on energy and environmental performance. The proposed decision support process is approved to be applicable for early design stages of the selected building, and helps creating consciousness about the importance of systematic design decision approach for the building professional.

    Life Cycle Environmetal Impact Assessment of a Multi-Storey Residential Building in Izmir
    (Izmir Institute of Technology, 2012) Aral, Duygu; Durmuş Arsan, Zeynep
    For a sustainable development, it is essential to improve the building stock and sector which are majorly affiliated with the negative impacts on environment. The analysis of current situation and establish the basic problems in order to decrease the environmental impacts of buildings. Life Cycle Assessment (LCA) is a holistic and scientific method in the area of environmental impact assessment. While the LCA may be applied to individual building components or specified life cycle phases, it is also possible to assess the environmental impacts of a building from cradle to grave with an integrated approach toward whole life cycle. The purposes of this study are to evaluate the current position of the LCA method, which is a vital component of the sustainability assessment in building sector, and to make a quantitative assessment on the environmental impacts of multi-storey-mass housing which has the primary share of recent residential building stock in Turkey. One residential unit of a mass housing development in Izmir constructed at the last decade, at the edge of the expanding city boundary, was selected as the case object of this study. The life cycle of building is fundamentally examined in three phases, which are: pre-use phase, use phase and end-of-life phase. The Simapro software 7.3.3 and Ecoinvent 2.2, up-to-date database, were selected for the LCA simulation. In addition, as a local input to database, energy data for Turkey was created. As a result of this study, the environmental impacts during the life cycle of a multi-storey building residential unit have been ascertained and the life phases, building components and operational processes which have the heaviest impact on the environment have been determined.

    A Critical View of Sustainable Architecture in Turkey: a Proposal for the Municipality of Seyrek
    (Izmir Institute of Technology, 2003) Durmuş Arsan, Zeynep; Erkarslan, Özlem
    This dissertation aims at developing a sustainable design process prioritizing locality in social, cultural, ecological, political, economic, technological, legalistic,and architectural terms. To this end, it aims first of all at developing an approach for elimination of misconceptions.primarily informed by technological, morphological and numerical indicators.about what constitutes the concept of sustainability in architectural practice today and therefore starts out from a critical historical overview of approaches and practices for sustainability in the world and in Turkey. The thesis undertakes the critique of sterile projects in sterile environments and calibrates the replicable and exemplary aspects of international and national sustainable design practices so as to introduce, promote and guide realistic, practicable, and case-specific sustainable architectural solutions. The specific focus in both the critical evaluation of extant sustainable practices abroad and the proposed process for the municipality of Seyrek in Menemen, Izmir, Turkey, is the distinction between the assets and needs of industrialized northern geographies and southern geographies which are in the process of industrialization and which are frequently misguided by economic exigencies imposed by the industrialized north. As a village located in an Important Bird Area, in the vicinity of a Ramsar Site and on the edge of a First-Degree Natural Conservation Area, the case area in question provides a trenchant example for the study of the meaning of sustainability in a southern socio-politico-economic zone and a challenge for the architectural designer. Seyrek is a mirror of global as well as local problems today. It is located in the middle of Gediz Delta, the large agricultural land as well, and on the edge of several specialized industrial districts of the urban sprawl of Izmir.Placing the analysis of the case area in the context of the wider framework of international policy, the thesis proceeds to propose specific design tools for a sustainable housing development project in a crucial typical new residential segment of the semi-rural settlement of Seyrek.
