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 The Peculiarities of Light as a Quality in Architecture(Izmir Institute of Technology, 2000) Kutlu, H. Gökhan; Erdoğdu Erkarslan, Özlem; Erkarslan, Özlem; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyThis study focuses on the evolution of lighting, both natural and artificial, and its effects on space. The twentieth century is taken as a focal time period, which had witnessed great developments in lighting field that caused inevitable transformations on space and spatial concepts. The evolution of artificial light, the significant innovations in building technology, and the new requirements formed under the desires of a new society are examined in their relation to architectural context with respond to light and lighting in space.The research includes cases from architectural and artistic world, and tries to investigate the role of light in the built environment. These cases are examined in a comparative way, considering the psychical and experiential characteristics of light in order to define its meaning for space.The study consists of two parts. In the first part the process of the evolution of lighting in the twentieth century, its position today, and the social, cultural, and technological alterations are examined deterministically. The second part is a classification of cases under the guidance of some concepts, which defines the interaction of light and space.
