Doctoral Thesis A Model for Assessing Acoustic Comfort in Enclosed Public Spaces(Izmir Institute of Technology, 2019) Çakır, Onurcan; İlal, Mustafa Emre; Çakır, Onurcan; İlal, Mustafa Emre; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyAcoustic comfort is one of the important topics in terms of user satisfaction. In order to determine and control acoustic comfort, measurable parameters are needed to be able to compare and improve soundscapes. Parameters for architectural acoustics, like reverberation time and sound pressure level are widely used for this purpose. Psychoacoustic parameters like loudness, sharpness, roughness and fluctuation strength are mostly used for determining the sound quality of mechanical sounds. They have also started to be used for evaluating soundscapes of open areas and enclosed spaces. This research aims to find out the relationship between the psychoacoustic parameters and acoustic comfort in non-acoustic enclosed public spaces, specifically in eating establishments. To reach this aim, both on-site measurements and in laboratory listening tests were conducted in five eating establishments. During on-site measurements, a simultaneous questionnaire study was also conducted. Subjective and objective data were comparatively evaluated. Listening tests were based on auralizations with calibrated simulation models. This provided a research model, that allows control over the acoustic environment without having to make real changes in the physical elements of the eating establishments. The auralization sound files were presented to listening test participants with headphones and they evaluated soundscapes with different psychoacoustic properties. The last chapter provides a summary of results and suggestions for future studies. Better acoustic comfort was found to be related with higher sharpness, lower reverberation time, lower loudness and lower roughness values for the examined parameter ranges.Master Thesis Project Plannig and Management Using Building Information Modeling (bim)(Izmir Institute of Technology, 2018) Politi, Ruti Ruth; Aktaş, Engin; İlal, Mustafa Emre; Aktaş, Engin; İlal, Mustafa Emre; 02.02. Department of Architecture; 03.03. Department of Civil Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology; 02. Faculty of ArchitectureToday, in construction practice, implementation of effective construction management techniques and tools is becoming essential, especially as the scale of the projects increases. Large scale projects pose a challenge to industry; as the number of tasks, parameters and constraints to be considered rises, interaction of these tasks and parameters increases the complexity, as well. While the search for techniques and tools for better coping with complexity will never end, Building Information Modeling (BIM) has recently emerged as an approach that achieves considerable improvement in efficiently handling complexity. BIM is able to provide a digital visualization of a building or structure in 3D. The necessary geometric data is modeled but more importantly all semantic data associated with the project (function of the element, material properties, construction details, schedules, etc.) is stored with the model. The intent is to have a single model of the project for all stakeholders over all phases of the project. In this study, the main challenges within the current practice of project management are analyzed and what BIM-based project management has to offer to those challenges have been discussed. The thesis explores how BIM method can be applied to project management and how information can be collected to build a BIM model. The advantages of BIM-based scheduling (4D), cost estimation (5D), sustainability (6D), facility management (7D) and structural analysis in the scope of project management is discussed. A case study is given to validate the use of the computer aided programs for nD BIM during the construction phase.Master Thesis Acoustic Design Based on Multi-Aspect Performance Analysis(Izmir Institute of Technology, 2013) Atça, Emre; İlal, Mustafa Emre; İlal, Mustafa Emre; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyIn current architectural practice, architects, due to time and budget constraints do not analyse their designs and evaluate alternatives from the building physics perspective. They expect this analysis to be carried out by engineers. Unfortunately, engineers mostly get involved late in the design process, after many key decisions are already finalized, leaving them powerless to solve problems employing efficient strategies. However, the rapid advances both in computing and engineering have produced various simulation based tools for evaluating building performance that architects themselves can employ in the early design stages. The proliferation of the utilization of these tools throughout the architectural practice and education is necessary for achieving higher performance levels in the built environment. In this study, the main Lecture Hall at Izmir Institute of Technology, Department of Mathematics is diagnosed and documented through measurements and the possibility of predicting this existing level of performance through simulations during the design stage is explored. The brand new Lecture Hall is in urgent need of renovations, with additional costs, in order to improve acoustic, visual and thermal comfort in the space. Architects need to follow a performance based design approach where they consider performance criteria and utilize building simulation tools for design support in order to avoid problems that introduce costs later in the construction and operation of buildings.
