    As the industry has expanded and the population has increased recently, so have the World's energy consumption and greenhouse gas emissions. Buildings are responsible for almost 40% of this consumption and emissions. They should be designed following energy-efficient and sustainable strategies. One of the most practical methods for increasing building energy efficiency and reducing environmental effects is building-integrated photovoltaic systems, which use solar energy to generate electricity on-site. This thesis explores the potential of photovoltaic glass technology in an architecture studio at the Izmir Institute of Technology Campus in Izmir, Turkey. The initial part of the study uses simulation modeling and field measurements in three scenarios to test the benefits of this technology in terms of thermal and lighting energy consumption and comfort levels. Scenarios included amorphous silicon thin-film modules in three transmittance values modeled in existing windows. Research findings propose that photovoltaic glasses have the potential to balance the room's lighting loads in a range between 15.1-and 20.3%. They improved occupant thermal and visual comfort by preventing overheating and glare risks. They also decreased cooling loads. Then, the study uses a genetic optimization algorithm to explore the optimum potential of the system in terms of annual energy consumption and daylight performance. Design variables are the window-to-wall ratio (i.e., window size and location) and amorphous-silicon thin-film solar cell transmittance to generate optimum Pareto-front solutions for the case building. Optimization objectives are minimizing annual thermal (i.e., heating and cooling) loads and maximizing Spatial Daylight Autonomy. Optimized results of Low-E semi-transparent amorphous-silicon photovoltaic modules applied on the window surface show that the Spatial Daylight Autonomy is increased to 82% with reduced glare risk and higher visual comfort for the occupants. Photovoltaic modules helped reduce the room's seasonal and annual lighting loads by up to 26.7%. Compared to non-optimized photovoltaic glass, they provide 23.2% more annual electrical energy.

    Professionals' Awareness on the Application and Use of Building Integrated Photovoltaic Systems
    (01. Izmir Institute of Technology, 2020) Tüten, Aysen; Kazanasmaz, Zehra Tuğçe; Kazanasmaz, Zehra Tuğçe; Kazanasmaz, Zehra Tuğçe; 02.02. Department of Architecture; 01. Izmir Institute of Technology; 02. Faculty of Architecture
    In this thesis research, broad definition of solar energy, photovoltaic systems and building integrated photovoltaic systems, their application forms, usage in building subcomponents and examples on the usage of building integrated photovoltaic systems are involved. By the application of the survey method, the awareness of professionals on the application and use of photovoltaic systems integrated into the building were examined. This questionnaire consists of 3 sections: the general definition of solar energy (A), the general description of photovoltaics integrated into the building (B), and the application of integrated photovoltaics to the building (C). The survey questions consist of multiple choice, matching questions, true-false questions and interpretation questions. The responses given to the questionnaire were analyzed in terms of the number of participants and percentage based by comparing them tabularly and diagrammatically. The importance of the study is to enable practitioners, academics, architects and engineers to realize their knowledge about BIPV systems, to understand the importance of these systems in terms of energy efficient design approach and to encourage them to use these systems in their projects. And thus, spreading the use of BIPV in our country and all over the world, leading them to realize the energy efficient design approach. In the first chapter; after the general introduction of the subject of the thesis, problem description, research objective, thesis content and methodology are mentioned. In the second chapter; the definition and technical problems of BIPV systems, usage areas of BIPV, case buildings, performance evaluations, market opportunities and applicability are mentioned. In the third chapter; the methodology section is included that consist of general information about the survey, survey questions and content, preselected buildings for the survey, information about the participants. In the fourth chapter; the results and analysis of the questionnaire, the comparison of the responses of the participants and the evaluation of the results, the comparison of the participant information and the literature information, and the evaluation of the results are included. The fifth chapter is devoted to results and evaluations.
