Article Citation - WoS: 3Citation - Scopus: 2User Lighting Preferences Based on Navigation and Space Quality in Virtual Exhibition Environments(Znack Publishing House, 2020) Çevik, Aslıhan; Kazanasmaz, Zehra Tuğçe; Duran, Hasan EnginJust as any other interior environment, lighting of exhibition spaces must be examined to enhance its visual quality and comfort. In this study, user behaviour, perception and impressions are analyzed for more comprehensive understanding by including subjective reasoning. Due to the chaotic progress and contradictory choices in exhibition lighting, daylight is mostly avoided while the role of users and relation between quantitative and qualitative parameters are often neglected. A series of sample exhibition spaces illuminated either artificially or by daylight are modelled virtually in Lumion software to be evaluated in a three-step questionnaire. A total of 90 participants are selected from three different professions (architects, visitors, artists), their reaction like movement, preference and impressions are gathered via questionnaire while moving through the model. The study aims to find out the role of lighting type in exhibition navigation and its relation with non-lighting parameters using statistical analysis methods. Results show that natural light is preferred more in sculpture exhibition while artificial light is preferred in painting exhibition. Movement towards daylight increases in transition areas and towards the end of the exhibition. A significant difference in navigation choices are found between professions, architects preferred to move towards more natural light while artists preferred artificial light.Article Citation - WoS: 2Citation - Scopus: 2An Empirical Validation of Estimation Model (optimlum) for Energy Efficient Luminaire Layout Design in Offices(Znack Publishing House, 2020) Uygun, İlknur Erlalelitepe; Kazanasmaz, Zehra Tuğçe; Kale, SerdarThis study performed with the purpose of constructing and validating a model named OptimLUM ( Optimizing Luminaire Layouts) to estimate the most accurate location, number and type of artificial light sources according to average illuminance and maximum uniformity in an office. OptimLUM is appling through Excel Spreadsheet to develop the model and uses Evolver, which is basing on genetic algorithm to implement optimization routine. To validate the reliability of the proposed model, luminaire layout scenairos generated for two types of luminaires after taking illuminance measurements in an actual office. OptimLUM illuminance values were comparing statistically with measurement and DIALux results to test the applicability of the model. The model performance is highly accurate in determining luminaire positions: coefficient of determination R-2 and coefficient of variation CV were equal to (86-99)% and to (0.04-0.12) respectively, and for all scenarios. Its outputs are closer to the actual measurements when compared with DIALux outputs.Conference Object Renovating a Lecture Hall With a Glass Roof: a Case Study of Performance Based Design(ÖKK-Editions, 2013) Atça, Emre; İlal, Mustafa Emre; Başaran, Tahsin; Kazanasmaz, Zehra Tuğçe; Durmuş Arsan, ZeynepIn practice, architects, due to time and budget constraints do not analyze designs and evaluate alternatives from the building physics perspective. They expect this analysis to be carried out by engineers. Engineers mostly get involved late in the design process, after key decisions are already finalized, leaving them powerless to solve problems efficiently. However, rapid advances both in computing and engineering have produced various simulation based tools for evaluating building performance that architects themselves can employ early in the design process. The proliferation of these tools throughout the architectural practice and education is necessary for achieving higher performance levels. In this study, the brand new Lecture Hall at Izmir Institute of Technology, Department of Mathematics that is in need of renovations to improve acoustic, visual and thermal comfort is diagnosed through measurements and the possibility of foreseeing, through simulations, the existing level of performance during the design stage is explored.
