Master Thesis Analysis of Building Information Modeling (bim) Performance Using Big Data From a Construction Project(01. Izmir Institute of Technology, 2023) Bostan, Berkay Batuhan; Çavka, Hasan BurakThis study aims to propose a systematical approach for evaluating BIM performance from a main contractor's perspective based on big data from a construction project. Retrospective case study is used as the research approach. Data is collected through interviews with the main contractor firm, and data from the logged project information in project databases including ACONEX and Microsoft Excel files. A framework containing performance metrics, specifically tailored to evaluate BIM performance based on big data, is developed from the combined analysis of literature review, interviews with main contractor, and overview of the project data. Collected project data and interview data are analyzed using the developed framework. Results of the data analysis are verified through follow-up interviews with the main contractor firm. Findings of the study suggest that it is possible to evaluate the BIM performance through analysis of collected BIM big data using the proposed systematical approach. Several performance problems were identified during the data analysis. Follow-up interviews revealed that identified performance problems from the data analysis largely coincided with the real-life experiences and accurate data entry is the key criterion for the analysis to yield correct results. The proposed framework should be tested in wider range of studies and may serve as a foundation for a future benchmarking system. Future work should focus on refining performance metrics, establishing a BIM big data database for benchmarking, exploring data's potential to be used for real-time performance assessment, and implementation of emerging Artificial Intelligence (AI) techniques for the analysis of big data.Master Thesis Evaluating the Effects of Tinted and Clear Glazing on Indoor Environment Perception, Visual Comfort, and View Quality(01. Izmir Institute of Technology, 2023) Coğul, Ilgın; Kazanasmaz, Zehra TuğçeIndoors 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.Master Thesis An Investigation of Performance Indicators for Stage Acoustics in Music Halls(01. Izmir Institute of Technology, 2023) Kuşcu, Duygu; İlal, Mustafa EmreIt is vital for concert halls to provide suitable acoustic conditions, as they provide the physical environment in which the communication between musicians and the audience is established. Although the acoustic conditions in these halls have been studied in detail for audiences, relatively little is known about the conditions under which musicians perform on stage and how they perceive acoustics. This thesis research investigates how the acoustics of the hall in which they perform are perceived by the musicians and how the objective data obtained through measurements carried out on stage matches the evaluations of the musicians through quantitative methods. Acoustic measurements were carried out in the Main Hall of the Ahmed Adnan Saygun Arts Center Izmir. Evaluations by the orchestra musicians about their own home stage were collected through questionnaires using a 10-point semantic differential scale for subjective acoustic parameters. A total of 33 musicians who regularly perform on this stage participated in the study as respondents. Compatibility between subjective data obtained from opinions and objective data obtained from measurements were compared. The main objective of this investigation was to scrutinize the tools and parameters that are recommended for acoustic design of concert hall stages, and provide further data for studies into understanding musicians' preferences and objective parameters that are being developed to reflect them. The correlations among subjective parameters on stage acoustics, were examined. Overall Acoustic Impression was found to be highly correlated with Hearing Others (0.833) and Support (0.753). This was supported by the objective measurements where STearly values were in a highly favorable range with a mean of -13.7 dB for this stage that is generally deemed to have good acoustics by musicians. The objective and subjective support parameters were found to be useful indicators within the limited context of Ahmet Adnan Saygun Arts Center Main Hall.Master Thesis Citation - Scopus: 21Multi-Objective Evolutionary Optimization of Photovoltaic Glass for Thermal, Daylight, and Energy Consideration(01. Izmir Institute of Technology, 2023) Taşer, Aybüke; Kazanasmaz, Zehra Tuğçe; Kundakcı Koyunbaba, BaşakAs 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.Master Thesis Comparatic-Ve Energy Performance Assesment of Hemp-Clay as Building Block Material(01. Izmir Institute of Technology, 2022) Ergün, Betül; Durmuş Arsan, Zeynep; Akkurt, SedatBio-based and earthen building materials have recently started to be used again in seeking sustainable materials to combat climate change. Hemp-based building materials stand out as energy-efficient materials due to their favorable thermal properties, although they still have unstandardized features that vary by location. This study aims to investigate the thermal properties and energy performance of hemp-clay building blocks which are produced with local hemp and clay in the western Aegean region of Turkey for today and the future, leading up the research on hemp-based building materials in the Mediterranean region. The methodology of the research consists of laboratory experiments on material and building energy simulations via DesignBuilder software. Building block samples were produced with 27 different hemp-clay mixtures and tested using a quick thermal conductivity meter. Subsequently, the thermal performance of selected hemp-clay block was compared with conventional wall infill materials such as hollow clay brick, autoclaved aerated concrete, and lightweight pumice block via simulations of the annual energy consumption of an existing residential building in Izmir. Simulation scenarios were generated keeping wall thickness and U-value as constant for the climate of 2020, 2050, and 2080. Hemp-clay building blocks reduced the heating and cooling demands of the case building by 21% and 14%, respectively in 2020. Their energy performance outperformed the other materials' performances even if the scenario walls have the same U-value as hemp-clay walls in today's and the future's climate conditions. Consequently, the hemp-clay building blocks are apparent as a promising material to be improved in Turkey.Master Thesis From Space To Junkspace: Four Episodes Of/In Architectural Theory(Izmir Institute of Technology, 2022) Yalçın, Zeynep Özge; Erten, ErdemThis thesis focuses on four concepts in architectural theory; space, place, nonplace, and junkspace, and points to understanding possible connections and relationships between these concepts. It aims to investigate how these relationships are established and possible causes in architectural history which might have led to their emergence and use by tracing the evolution of these concepts through a literature review. The discussion will be framed around episodes of debate on the concepts regarding the history of architectural theory. Conceptualized as a force field generated by the dynamism of bodily movement, the understanding of space by empathy theory profoundly influenced modern architecture. Modern architecture’s preoccupation with space was criticized with recourse to the concept of place. Anticipating postmodernist sensitivity place challenged the dominance of space. However, the focus on place, in opposition to space, was also criticized for the tendency to create scenographic effects driven by commercial interest. The “production” of “places” was followed by the definition of two important concepts: “non-place” by Augé and “junkspace” by Koolhaas. By reading the debates around these four concepts as episodes of/in architectural theory, I not only aim to see the relations between these concepts but also understand how the impact of globalization is visible regarding “non-place” and “junkspace.”Master Thesis Intuition an Intuitive Thinking in Architectural Design: the Case Study of Gön Leather Factory by Nevzat Sayın(Izmir Institute of Technology, 2022) Türkoğlu, Kardelen; Doğan, FehmiThe concept of intuition has been one of the cornerstones of the philosophy of knowledge since antiquity. It has been used in different disciplines with distinctive meanings, but it has remained an unclear phenomenon. In particular, the term has been researched in philosophy and art, and the concept has been interpreted in different theoretical frameworks. The discipline of architecture, which is related to these fields, is often considered to be a problem-solving effort. This view highlights the rationalization attitude in modern architecture. In addition to this rationality, the unpredictable, multi-disciplinary, and open-ended structure of architectural practice makes the concepts of intuition and intuitive thinking an inseparable part of the architectural design process. Within the scope of the thesis, the role of intuition and intuitive thinking in the architectural design process has been examined. In the literature, commonly, architecture is interrelated with philosophy, art, and mathematics due to its scope. Moreover, intuitive thinking stands out as a concept related to the designer's historical background and level of expertise. In this framework, intuition in architecture is discussed in inference to the concept of intuition in philosophy, art, and mathematics and the idea of intuitive thinking based on experience. In addition, the notion is a subjective concept, and it has a structure with different expansions on the subject scale. At this juncture, intuition and intuitive thinking are examined and analyzed through the works of Architect Nevzat Sayın.Master Thesis Virtual Acoustic Reconstruction of Two Ancient Spaces: Metropolis Ancient Theatre and Eflatun Pınar Open Air Water Sanctuary(Izmir Institute of Technology, 2022) Bolat, Senem Deniz; İlal, Mustafa EmrePhysical damage caused by various natural events or incorrect uses causes the original acoustics of historical places to be lost over time. In this context, protecting and maintaining the acoustic heritage of historical places which stand out with their acoustic characteristics becomes a crucial subject. Metropolis Ancient Theatre and Hittite Open Air Water Sanctuary are two historical places where acoustic character is at the forefront. In this study, acoustics of these two spaces in their original state is reconstructed. Firstly, original purpose of use for the Metropolis Ancient Theatre is investigated. In accordance with the original use scenario, a study is conducted in which passive interventions were explored for performances at the orchestra level and on stage in the present state of the theatre. This intervention provides a guidance on how the theatre can be best utilized for the future events suitable to its original use scenario, today. Secondly, acoustics of the Hittite Open Air Water Sanctuary is reconstructed through virtual acoustic simulations. In the Hittite culture, it is well-known that water plays a significant role in everyday life. Through an auralization study, the acoustic environment during religious ceremonies, celebrations and sacrificial rituals is explored. How the constant sounds of flowing water affects perception of musical instruments played around the sanctuary is investigated through the virtual reconstruction of the space. Both of the two case studies are chosen to explore their original acoustics using two different methods which include objective evaluation for Metropolis and subjective evaluation for Eflatun Pınar. Within the scope of virtual acoustic reconstruction studies, the validity of two different methods is aimed to be investigated under a single study. With virtual acoustic reconstructions, experiencing the acoustic memory of historical places becomes possible. With the similar studies in this field, acoustic memory is aimed to be preserved in accordance with its original purpose of use within the scope of acoustic heritage, in a very general sense.Master Thesis The Effects of Spatial Layout of Healthcare Facilities on Staff Communication(Izmir Institute of Technology, 2022) İleri, Nurcan; Kasalı, Altuğ; Doğan, FehmiThe space occupancy patterns of staff stand out as one of the basic function of spatial configurations that affects communication, behavior and teamwork in healthcare facilities. There is a strong relationship between staff communication, behavior and the occupancy of space in healthcare facilities, since space is considered as a primary factor to shape the modes of interaction involving occupants and care protocols. This study focuses on the space occupancy of nurses working in inpatient units (IU) as the primary form of data, and comparatively examines three different IUs with different spatial layouts, and contrasts and compares differences within. This research brings together different methods including on-site (observations, surveys, and interviews) and off-site (space syntax and statistical analysis) analytical techniques to understand the distinctive dimensions of space such as accessibility, visibility, and physical proximity. The findings of the study reveal the potential effects of different spatial layouts and space organizations to create different densities on circulation loads, which may in turn impact occupancy, accessibility, and visibility, and also communication within the unit. Although there are morphological differences between the three units, the findings suggest that particular key areas emerge to affect occupancy. There are particular zones -to attract dense circulation- observed in the units involving staff-related areas (nurse stations, nurse rooms, and medication preparation rooms) across the corridors in units. In addition to these particular staff-related areas, the different locations including break rooms and unit secretary workstations also emerged as locations where high levels of occupancy involving staff, patients, and visitors, was observed.Master Thesis The Effect of Restoration Interventions on the Indoor Climate of Historic Buildings: Case Study of Tire Necip Paşa Library, İzmir, Turkey(Izmir Institute of Technology, 2022) Çağırgan, Umut; Durmuş Arsan, Zeynep; Gökçen Akkurt, GüldenLibraries are collections of recorded information which can host cultural heritage values that must be protected against mechanical, chemical and biological degradation. To prevent degradations, libraries require stable indoor climates with minimal temperature and relative humidity fluctuations and low concentrations of indoor air pollutants. Aim of the thesis is to investigate if installing a HVAC system is effective in improving the indoor climate of a historic library as a long-term preventive conservation method on the preservation of paper-based collections. Tire Necip Paşa Library in İzmir was selected as the case building which underwent restoration and a HVAC system integration in 2015. Library’s indoor climate was investigated before 2015 which allowed the comparison of pre- and post-restoration periods. Within the scope of this thesis, library was monitored at five locations between 2019-2021. 2019-2020 monitoring results were compared to pre-restoration monitoring results in terms of degradation risks and ASHRAE Chapter 23 control classes. Pre- and post-restoration indoor climates satisfied A1 and AA control classes, respectively. While there were mechanical and chemical degradation risks before restoration, no risk was observed post-restoration. There was no biological degradation risk during either periods. Additionally air pollutants were sampled during summer and winter of 2020-2021 which showed high SO2 and NO2 concentrations. Lastly the BES model of library was prepared and calibrated to investigate if existing HVAC system will continue to provide a stable indoor climate on future. The results of 2050 and 2080 simulations showed that HVAC system will struggle to provide a stable indoor climate.
