    Evaluating the Effects of Tinted and Clear Glazing on Indoor Environment Perception, Visual Comfort, and View Quality
    (01. Izmir Institute of Technology, 2023) Kazanasmaz, Zehra Tuğçe; Kazanasmaz, Zehra Tuğçe; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    Indoors are essential in people's lives because most of the time is spent here. Therefore, indoor quality and comfort should be provided. One parameter affecting this quality and comfort is lighting. Although the importance of natural lighting comes to the forefront in sustainability studies, many variables must be taken into account while providing successful lighting conditions. This thesis investigates the effects of glazing transmittance, colors, and view types on visual comfort and occupants' indoor perception and impact of the specified glazing parameters on the view quality. Room types combined with various glazing and view types were modeled and asked people through a questionnaire about how interesting, pleasant, and bright the rooms and pleasantness of the view are perceived by people. While subjective opinions were analyzed with statistical methods, calculated illuminance and luminance values of the rooms were compared with survey results. In the results, it was found that the glazing color has a significant impact on the perception of the interior. While the yellow glazing offers an interesting experience to the occupants, these rooms were not found pleasant. Yellow glazing combined with the street view was the most unpleasant interior. Medium-transmittance glazing type and the nature view was evaluated as the most pleasant room. Although the glass with the highest transmittance causes very high illuminance values in the rooms, it is most preferred room for brightness. As a result, perceptions change according to the characteristics of the interior, and they should be taken into account when designing these spaces.

    Multi-Objective Evolutionary Optimization of Photovoltaic Glass for Thermal, Daylight, and Energy Consideration
    (01. Izmir Institute of Technology, 2023) Kazanasmaz, Zehra Tuğçe; Kazanasmaz, Zehra Tuğçe; Kundakcı Koyunbaba, Başak; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    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.

    Effectiveness of Retail Lighting in Terms of User Satisfaction and Light Quality
    (01. Izmir Institute of Technology, 2021) Kazanasmaz, Zehra Tuğçe; Kazanasmaz, Zehra Tuğçe; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    The primary purpose of lighting design is to create visuality that can perform different tasks and perceive spaces and objects it means that visual comfort conditions. Visual comfort related with the quantity and quality of light. There are some points to be considered in order to ensure the lighting design that changes/determines according to the standards of each environment: light amount, color, direction, color rendering, and uniformity of light. All these determine the quality of lighting in the environment. Effectiveness of retail lighting related with how to design retail stores. In this study, which examines the effect of retail lighting in terms of human satisfaction and light quality, firstly what lighting is, its purposes and benefits are discussed. Then, necessary visual comfort conditions for stores, brand images and strategies, standards and requirements of lighting designs for customers are mentioned. This information was gathered by examining the main sources of lighting standards. In the studies conducted on this subject, it has been determined that there are incomplete studies examining "different age groups, socio-cultural groups, different store profiles, daylight effects and customer/employee satisfaction". For this reason, a survey was conducted in Boyner and DeFacto stores in İzmir Westpark AVM to support the study, and it was emphasized the effectiveness of lighting designs in terms of users' satisfaction and light quality.

    The Effects of Lighting Conditions on Visual Comfort, Satisfaction and Motivation Levels of Architecture Students
    (01. Izmir Institute of Technology, 2021) Durgut, Merve; Kazanasmaz, Zehra Tuğçe; Durgut, Merve; Kazanasmaz, Zehra Tuğçe; 02.02. Department of Architecture; 01. Izmir Institute of Technology; 02. Faculty of Architecture
    Education is a significant part of human life as people spend important part of their lives in learning spaces. Various studies indicate that the quality of physical environment in learning spaces has a crucial impact on students' mood, motivation, performance, productivity, health, and well-being. There are many different physical conditions in an environment and among these factors lighting is one of the most important ones as it is a visible condition. Although there is a wealth of research on the effects of lighting conditions on students' learning, well-being, visual comfort, and performance in regular classrooms, there is a dearth of research about lighting conditions' effects in architecture design studios. Moreover, while research on the effects of lighting conditions on students' performance and well-being is abundant research that focuses on motivation levels of the students is scarce. In this regard, the aim of this study is to investigate how lighting conditions affect the visual comfort, satisfaction, and motivation levels of architecture students. Field measurements and surveys were utilized in three architecture studios. Findings demonstrated that lighting conditions have an important impact on students' visual comfort, satisfaction, and motivation levels. Lack of daylight illuminance, glare, improper artificial lighting, and insufficient lighting were all found to contribute to inappropriate lighting conditions. Lighting conditions have also been found to affect seating preference of users. Seating arrangement and distance from windows affected the perception of users regarding lighting conditions. Based upon the results, some suggestions that would help resolve problems caused by inappropriate lighting were also offered.
