Master Thesis Performance of Movable Façade Panels in Terms of Dynamic Daylight Metrics for a Classroom(Izmir Institute of Technology, 2020) Keskinel, Yeşim; Kazanasmaz, Zehra Tuğçe; Kazanasmaz, Zehra Tuğçe; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyAlthough the use of daylight has an important role in educational spaces, uncontrolled use of daylight can lead to some undesirable situations for occupants. It is generally accepted that recommended illuminance values change between 300 lux and 2000 lux in educational spaces. However, it is not possible to get these illuminance range at the same level during the day, as the classrooms have been used all day period. To create more satisfied daylit spaces, movable shading systems become a solution because of their ability of guiding the direct daylight in day period. To evaluate the daylight performance of movable shading systems, dynamic daylight performance metrics have been used. This thesis focuses on comparing different types of movable shading systems developed as a result of findings of dynamic daylight metrics in a classroom. A classroom in the Department of Architecture in Izmir Institute of Technology was chosen as the case room measured illuminance values. It has been found that the level of illuminance values are much higher than the generally accepted values. The classroom has been modelled virtually and analyzed on a special software programmer in order to examine the findings of the field measurement. Two different types of moveable shading systems have been suggested and used to evaluate the performance of illuminance. When the results are evaluated, it can be understood that movable shading systems have a significant role on creating satisfied spaces in educational areas. Especially, single oriented shading systems, which represented as model 1 in thesis, are more successful to control direct daylight.Master Thesis The Influence of a New Layout Arrangement and a Light Shelf-Reflective Louver System on Satisfying Visual Conditions in Academic Library Reading Room(Izmir Institute of Technology, 2017) Öner, Merve; Kazanasmaz, Zehra Tuğçe; Kazanasmaz, Zehra Tuğçe; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyHigly glazed facades has been increasing with the intention of more daylight gain in buildings. However, more daylight may not always bring more satisfaction considering many factors that influence daylighting quality. Uncontrolled daylight brings visual and thermal problems which end up with negative interactions with user comfort. Library spaces in which different task activities are performed simultaneously need to be well designed in terms of daylight performance, thus the user satisfaction could enhance. This thesis particularly focuses on the optimization of visual performance in an academic library with a new layout arrangement and a light shelf-reflective louver system. One of the reading rooms of Izmir Institute of Technology Library was chosen as a reference case, where the instrumental monitoring of existing daylighting conditions was performed. The reference case was then analyzed with daylight simulation tool, so that the outcomes would later be used for the performance testing of the new proposals. Luminance patterns and illuminance distribution of different points were evaluated in terms of visual performance recommendations. A new layout arrangement and light shelf-reflective louver system were proposed respectively in accordance with the deficiencies of simulation results. Ultimately, daylight performance of the library was significantly improved regarding illuminance and luminance based distribution. Despite a diminution in average illuminance due to the dramatic decrease of excessive amount of daylight near the window, the big picture gives the clues on how a simple layout change and a daylighting system can make enhancement on the visual performance of a library reading room.Master Thesis Simultaneous Improvement in Visual and Acoustic Performance by Modifying Common Design Components in Lecture Halls(Izmir Institute of Technology, 2017) Öztürk, Yasemin; Kazanasmaz, Zehra Tuğçe; Kazanasmaz, Zehra Tuğçe; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyProviding indoor comfort conditions at optimum level in educational buildings increases the concentration, the desire for learning and occupants’ performance. The learning environment’s appeal for students and teachers are mostly derived from their visual and aural sensations. So, properly-designed lighting and acoustic conditions have become an important concern. Daylighting is a component of energy saving strategy. It provides visual performance and comfort to support executing tasks, additionally to achieve aesthetic and occupants’ appraisal of the physical environment. However, too high background noise and low intelligibility lead to disturbance in hearing and understanding. Such problems mainly cause the lack of concentration, which disturb occupants’ satisfaction with the indoor acoustic environment. Both students and lecturers raise their voices to communicate better when there is poor reverberation and clarity. Yet, measures and precautions to improve one aspect are not enough. Designers/researchers can establish an integrated approach to deal with the aspects of daylighting and acoustics under common design criteria; since, one design alternative developed to improve sound distribution modifies the visual performance either in an effective way or in an unfavorable way. It is necessary to propose common design alternatives, such as ceiling geometry, seating layout and material combination to conclude simultaneous enhancement in visual and acoustic performance. To achieve that, this thesis presents analyses of DIALux and ODEON models of a lecture hall proposing design component choices for ceiling geometry, seating layout, and material combinations. Simulation findings direct out attention to how to design a lecture hall in an integrated approach.Master Thesis Overview and Discussion on Recent Applications of Building Integrated Daylighting Systems and Photovoltaics(Izmir Institute of Technology, 2017) Dim, Didem; Kazanasmaz, Zehra Tuğçe; Kazanasmaz, Zehra Tuğçe; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyConsumption 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.Master Thesis A Prediction Model for Daylighting Illuminance for Office Buildings(Izmir Institute of Technology, 2008) Binol, Selcen; Kazanasmaz, Zehra Tuğçe; Kazanasmaz, Zehra Tuğçe; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyDaylight is a primary light source for the office buildings where a comfortable and an efficient working environment should be provided mostly during day time. Evidence that daylight is desirable can be found in research as well as in observations of human behavior and the arrangement of office space. A prediction model was then developed to determine daylight illuminance for the office buildings by using Artificial Neural Networks (ANNs). A field study was performed to collect illuminance data for four months in the subject building of the Faculty of Architecture in .zmir Institute of technology. The study then involved the weather data obtained from the local Weather Station and building parameters from the architectural drawings. A three-layer ANNs model of feed-forward type was constructed by utilizing these parameters. Input variables were date, hour, outdoor temperature, solar radiation, humidity, UV Index, UV dose, distance to windows, number of windows, orientation of rooms, floor identification, room dimensions and point identification. Illuminance was used as the output variable. The first 80 of the data sets were used for training and the remaining 20 for testing the model. Microsoft Excel Solver used simplex optimization method for the optimal weights. Results showed that the prediction power of the model was almost 97.8%. Thus the model was successful within the sample measurements. NeuroSolutions Software performed the sensitivity analysis of the model. On the top of daylight consideration, this model can supply beneficial inputs in designing stage and in daylighting performance assessment of buildings by making predictions and comparisons. Investigation about this subject can be able to support the office buildings. having intended daylighting comfort conditions.Master Thesis Modeling of Advanced Daylighting Systems To Imporove Illuminance and Uniformity in Architectural Design Studios(Izmir Institute of Technology, 2013) Fırat Örs, Pelin; Kazanasmaz, Zehra Tuğçe; Kazanasmaz, Zehra Tuğçe; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyThe daylighting performance is an important asset that deeply affects the occupant's visual comfort. In study and work environments, it is crucial to maintain adequate and uniformly distributed daylight. Deficiencies in daylighting conditions of these environments may cause health problems, work performance loss and excessive energy consumption. The varying nature of daylight in daily and yearly basis is a strong challenge on that matter. Advanced daylighting systems have been developed to overcome this challenge. Improving the daylighting performance of existing buildings is another difficulty in daylighting design, since the aspects like orientation, window area and surrounding elements affect indoor illuminance levels and uniformity. Thus, daylighting design needs should be carefully considered at the initial design stages of the buildings. Regarding to these, four architectural design studios facing southwest, southeast, northwest and northeast were selected in Izmir Institute of Technology Faculty of Architecture. In these studios, daylighting measurements including illuminance at specific points were conducted in May and June 2012. The aim of this thesis is to improve the illuminance and uniformity in the selected studios. Simulation models were built in Ecotect; and the field measurements were then used to validate the Ecotect model. To reach the best daylighting performance, simulations were carried out by Desktop Radiance with applying advanced daylighting systems, namely laser cut panels, prismatic panels and light shelves. The simulation findings were analyzed and discussed. It is considered that retrofitting efforts after the construction would be inadequate regarding daylighting, unless complying with the standards during the design process.Master Thesis The Impact of Architectural Design Criteria on Energy Performance of Residential Buildings: a Case Study in Izmir(Izmir Institute of Technology, 2012) Uygun, İlknur; Kazanasmaz, Zehra Tuğçe; Kazanasmaz, Zehra Tuğçe; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyThe impact of architectural configuration and design norms on energy performance of buildings has been a critical issue. Even, it becomes noteworthy for residential buildings of good quality. New legislation in Turkey which was prepared to comply for the latest European Energy Performance of Buildings Directive 2010/31/EC requires information about the evaluation of energy performance of existing buildings. So, this study aimed to determine energy performance of residential buildings in Izmir, to analyze significant relationships between their performance and architectural configuration through statistical analyses (analysis of variance (ANOVA), regression, t-Test, scatter charts). Utilizing production drawings, certain area-based ratios and building dimensions were determined as architectural configuration indicators. Most prevailing architectural variables, such as, zoning status, external surface area and A/V ratios, and others, namely, orientation, floor counts in a building, aspect ratio, heating system were analyzed. Energy performance of case buildings were determined by using The Standard Assessment Method for Energy Performance of Dwellings (KEP-SDM) which referred to Turkish standard TS 825, and European standard EB ISO 13790. Majority of the investigated buildings were in Energy Class B and C, in CO2 Class G; however, their energy consumption values were two times higher than the ones in European countries. Findings present such a clue that interactions between variables and their total effect on the energy performance and CO2 emissions should be taken into consideration. They would also provide feedback information on the residential building stock in İzmir, selected as a representative city in Turkey.Master Thesis Thermal comfort evaluation in intelligent buildings; case study in Darüşşafaka Residence(Izmir Institute of Technology, 2009) Soykan, Esra; Kazanasmaz, Zehra Tuğçe; Kazanasmaz, Zehra Tuğçe; 02.02.
