    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..

    Overview and Discussion on Recent Applications of Building Integrated Daylighting Systems and Photovoltaics
    (Izmir Institute of Technology, 2017) Dim, Didem; Kazanasmaz, Zehra Tuğçe
    Consumption of energy resources has been increased with industrial revolutions, and today it is continuing. As a matter of fact, one of the biggest results of this negative increase is global warming. In this respect, studies are being carried out for more sparing consumption of natural energy resources (water, mines, fossil fuels etc.). As well as work and applications for more common and correct use of renewable energy sources such as solar and wind energy. This study has emerged through the examination of the concept of "architecture integration". Today, the necessity and the positive increase in the use of renewable energy sources have led to the emergence of integrated energy systems with the building. Therefore, renewable energy resources are being used more actively with subsystems that provide integration between building and ecosystem. Renewable energy sources are energy resources that benefit from natural processes for energy and can renew themselves faster than resources are consumed. Solar energy, wind energy, geothermal energy are the main sources of renewable energy. In this study, daylighting systems and photovoltaic applications, which are subsystems of solar energy and building integration as a result of renewable energy sources, are examined. During the research, it was considered how the systems are integrated into the building, their levels, design and structural characteristics and how they are used and reviewed through tabularized forms. As a result, it has been determined that the shape and features of integration vary according to the building form, environmental factors, and requirements of construction.

    Environmental Impact and Capacity Analysis of Renewable Energy Resources: Case Study of Wind Energy in Turkey
    (Izmir Institute of Technology, 2016) Değirmenci, Sinem; Bingöl, Ferhat; Sofuoğlu, Sait Cemil; Bingöl, Ferhat; Sofuoğlu, Sait Cemil
    The majority of electricity in Turkey is generated from coal and natural gas; however, renewable energy, especially wind power, is a promising energy source for Turkey. Development of new wind energy project requires complex planning process involving many social, technical, economic, environmental, political concerns and different agents such as investors, utilities, governmental agencies or social groups. To address the proper site selection, a Geographic Information System (GIS) based Multi- Criteria Decision-Making (MCDM) method has been used in previous studies. The aim of this study is to develop a GIS-based multi-criteria decision making application which can be updated by the changing regulations to identify potential sites for wind power plants in Turkey. A variety of constraints and factors were identified based on a literature review, regulations and gathered from variety of agencies. After excluding of infeasible sites, pairwise comparisons was carried out using analytic hierarchy process (AHP) as MCDM method by the study group to estimate relative importance of the criteria. The suitability map obtained from MCDM analysis was divided into four classes from the low suitable to extremely suitable area. As a final stage, decision making was carried out with the objectives by environmental impact approach. The output of this study can be used by energy planners to estimate the extent that wind energy can be developed based on public perception, administrative and environmental aspects.
