Article Citation - WoS: 5Citation - Scopus: 5Comparison of Advanced Daylighting Systems To Improve Illuminance and Uniformity Through Simulation Modelling(Znack Publishing House, 2014) Kazanasmaz, Zehra Tuğçe; Fırat Örs, PelinDeficiencies in daylighting performance (illuminance and uniformity) of educational facilities 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. Daylighting design needs should be carefully considered at the initial design stages of the buildings. So, the aim of this study was to improve the illuminance and uniformity in four selected architectural design studios in Izmir. Measurements of daylight illuminance were conducted in May and June 2012. Simulation models were built in Ecotect/Radiance. To reach the best daylighting performance, simulations were carried out by Desktop Radiance with applying laser cut panels, prismatic panels and light shelves. It is considered that retrofitting efforts after the construction would be inadequate regarding daylighting, unless complying with the standards during the design process.Other The Levantines: Commerce & Diplomacy(Intellect Ltd., 2016) Amygdalou, Kalliopi[No abstract available]Article Citation - WoS: 1Citation - Scopus: 1Impact of Thermal Mass for Future Energy Consumption: Case Study in Adobe House(Inderscience Enterprises, 2019) Durmuş Arsan, Zeynep; Yöney, Ekin GamzeThis paper examines thermal mass quality of building envelope as passive preventive phenomena for future energy consumption. It questions how much and what type of thermal mass is required for decreasing energy consumption according to future climate change. Summer energy performance of adobe house in Konya, Turkey is studied in terms of thermal mass characteristic by using dynamic simulation software. Measured and predicted microclimate data for 2017 and 2050s are used to compare passive impact of wall material choices, i.e. adobe, limestone, vertical hollow brick and volume of wall without night-time ventilation. In conclusion, the study reveals that thermal mass with lower density and thinner materials show higher energy performance for summers. Energy consumption is minimum with vertical hollow brick wall in 50 cm for 2017 and 30 cm for 2050s. It is deduced that thermal conductivity will still have higher impact than thermal mass on energy consumption.Article Citation - WoS: 6Citation - Scopus: 9Impact of Climate Change on Indoor Environment of Historic Libraries in Mediterranean Climate Zone(Inderscience Enterprises, 2019) Turhan, Cihan; Durmuş Arsan, Zeynep; Gökçen Akkurt, GüldenMost historic library buildings house valuable paper-based collections that are kept in unconditioned environments. This vulnerable cultural heritage is expected to be highly affected by climate change in the future. In this study, indoor microclimate of an unconditioned historic library, Necip Pasa Library (Izmir, Turkey) is analysed for existing conditions and future climate data. The measured and predicted indoor microclimate data from 'present' till 2080s are used to determine possible chemical degredation risk on library collection and human comfort. Comparison of periodic results of future climate data indicates an increase in temperature that could cause both an increase in chemical degredation risk on the library collection and a decline in thermal comfort conditions. Mitigation of climate change effects on library collection and human comfort requires taking some actions such as adding light and adaptive mechanical solutions.Article Citation - Scopus: 1The Impacts of Window To Wall Ratio and Window Orientation on Building Energy Consumption and Co2 Emissions Under Climate Change(Inderscience Enterprises, 2019) Gerçek, Mümine; Güçü, İlkerDecisions about the openings of the buildings play crucial role for improvements in recent and future energy and environmental performance characteristics. Therefore, the effects of window to wall ratio and window orientation on building annual heating, cooling energy consumptions and operational CO2 emissions are investigated regarding recent (2018) and future weather conditions (2050s and 2080s) of Izmir. The simulation model of a typical office building is created, and several scenarios are generated, including four facade orientations and different window to wall ratios, simultaneously. Then, the impacts of retrofits in window characteristics on building performance under climate change are examined for Izmir and Ankara. Finally, the results are evaluated in terms of different weather conditions to reach the most efficient opening design alternative. Considering the average life time of buildings, the outcomes of this study can be used as additional data for understanding the relation between transparent surface design and energy, environmental performance of buildings.Article Citation - WoS: 4Citation - Scopus: 5Illuminance and Luminance Based Ratios in the Scope of Performance Testing of a Light Shelf-Reflective Louver System in a Library Reading Room(Znack Publishing House, 2019) Öner, Merve; Kazanasmaz, Zehra TuğçeUncontrolled daylight brings visual and thermal problems that may result in negative interactions with user comfort, productivity, well-being, and human health. Library spaces, in which reading, writing, and computer task activities are performed, need to be well designed in terms of daylight performance to enhance user satisfaction. The focus of this study is to make a performance test of a light shelf-reflective louver system to improve the visual performance conditions of a library reading room. First, the instrumental monitoring of existing daylighting conditions was performed. Second, Relux model was prepared to evaluate luminance patterns and illuminance distribution. Third, a new light shelf-reflective louver system was proposed based on the insufficiencies of the simulation results. The performance of the new system was found highly satisfactory based on the findings of enhanced luminance patterns and uniformity ratios especially at the points near the windows.Article Citation - WoS: 1Citation - Scopus: 6Examining Occupancy and Architectural Aspects Affecting Manual Lighting Control Behaviour in Offices Based on a User Survey(Znack Publishing House, 2018) Cilasun Kunduracı, Arzu; Kazanasmaz, Zehra Tuğçe; Hordijk, TruusFurther understanding the building occupants’ needs and behaviors can reduce lighting energy consumption. This research explores how the occupancy and interior architectural aspects become effective in manual lighting control in offices. It involves a multiple sectioned questionnaire focusing on the possible architectural factors such as the desk position, the surface colours, the distance to window, the distance between desk and lighting switch, and inquiring participants’ manual lighting control behaviour through the photographs of modified interior layouts, surface colours and time intervals. Statistical methods are used to determine the significant aspects, which may reduce the use of lighting control. Interior layout, distance to window, time of the day, and number of occupants in the offices are the most significant contributions to the manual lighting control behaviour. To pay attention in these contributions, it would be possible to reduce the use of electricity for lighting while user satisfaction increases.Article Citation - WoS: 7Citation - Scopus: 9Simulation-Based Retrofitting of an Educational Building in Terms of Optimum Shading Device and Energy Efficient Artificial Lighting Criteria(Znack Publishing House, 2016) Bayram, Göze; Kazanasmaz, Zehra TuğçeThe high level of daylight performance is crucial to increase academic and work performance of students and staff in educational buildings which are mostly used during the daytime. New design solutions have potential to reach optimum lighting conditions and minimum energy consumption. So, the purpose of this study is to evaluate and propose an energy efficient lighting design for an educational building. The aim is to find the optimum type of shading device with appropriate slat angles, transmittance of glazing, and the luminaire type/layout as well. Utilizing DIALux simulations, scenarios for combinations of these inputs are tested for classrooms, offices and a laboratory, which are non-identical due to their orientation, size, window characterization and facade organization. The procedure covers all significant days (winter/ summer solstice and equinoxes) during one year. Such an integrated approach would be proposed for lighting design and retrofit applications. © 2016, LLC Editorial of Journal “Light Technik”. All rights reserved.
