Article User Satisfactions on Visual Comfort and View Quality Based on Colours and Opacity of Glazing To Control Daylighting(Znack Publishing House, 2023) Cogul, Ilgin; Duran, Hasan Engin; Kazanasmaz, Zehra TugceWindows are both components that open to the outside and gates that bring the outside elements inside as well. The visible view through windows affects users' perception of the indoor environment. Visual comfort is a key concern to create qualified interior spaces. Glazing type in naturally lit environments becomes very substantial for comfort. As glazing technologies develop, the options available for users have also increased. This study aims to find out how different glazing and view types impact user perception and satisfaction in the interior and to create design ideas for the spaces to be completed in the future. A room with various glazing transmittance (20 %, 50 %, and 90 %), colours (blue and yellow), and view types (street and landscape) are modelled virtually in Relux. A survey composed of these rendered scenes from these variations includes four questions. 40 people participated in the survey. Statistical analyses are made using Stata and EViews. Illuminance and luminance are calculated via Relux to discuss quantifiable values and subjective one together. According to the results, as transmittance increase, the rate of people finding the room pleasant and the quality of the view decrease, but a brighter environment shows up. When using tinted glazing, users mark the rooms as interesting, while pleasantness and view quality decrease. A landscape view instead of a street view in the rooms results is a more interesting, pleasant indoor environment, and higher view satisfaction.Book Review Citation - WoS: 1Randa Aboubakr, Sarah Jurkiewicz, Hicham Ait-Mansour, and Ulrike Freitag, Eds.

In this context, a mathematical model considering user behavior and window aluminum frame element effect was build by zonal analysis method to calculate the heat transfer in single and box type closed cavity double skin façade systems, and build model was experimentally verified. Experimental study was conducted in office spaces having single and double skin façade systems in Ege University, Civil Engineering Building’s south façade in January 2017. Next, verified model was used to study the heat transfer in the façade systems for İzmir’s climatic condition by using monthly average daily data. The change in thermal performance of single and double skin façade systems due to the climatic condition during a year was investigated by using the 10 year average climate data of İzmir (Mediterranean climate). It was found that double skin façade system acts as an insulator preventing extreme indoor temperature values, thus contributing to the indoor comfort level against changing outdoor conditions. ©2021 TIBTD Printed in Turkey.Article Citation - WoS: 1Citation - Scopus: 1Approaches To Optimization for Movable Shading Systems: a Review of Optimization Methods and Tools(Znack Publishing House, 2021) Keskinel, Yeşim; İlal, Mustafa EmreStudies show that movable shading systems have lots of benefits for building performance. Minimizing energy consumption and maximizing daylight usage are natural expectations when using these systems. To find optimal solutions for these systems, different methods have been used. Today, optimization methods are used to solve this problem. In the literature, there are few studies about optimization of movable shading systems. This paper aims to identify different movable shading systems, optimization types, and computational optimization tools that are used. Research findings and future projections based on the reviewed papers are summarized.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.Article Citation - WoS: 7Citation - Scopus: 7Applicability of a Prismatic Panel To Optimize Window Size and Depth of a South-Facing Room for a Better Daylight Performance(Znack Publishing House, 2020) Köse, Büşra; Kazanasmaz, Zehra TuğçeThis study examines the performance of attached prismatic panels, which have shading capability, in a side-lit deep plan room to find out the least possible WWR value in relation to room depth satisfying the required daylight availability. The methodology is based on simulating a base model in Relux and testing it with alternative models composed of incrementally defined WWR and room depth values. In accordance with minimum IES requirements, the most satisfying sDA value was found to be 48.54 % in a room of 12 m depth with 67 % WWR. An sDA of 51.59 % and 59.26 % was achieved in a room of 9m depth with 43 % WWR and 6m depth with 30 % WWR, respectively. The least ASE values were obtained with the least WWR alternative of 30 % in all room depths. This study presents a new approach with the consideration of innovative daylight redirecting systems to propose revisions for the requirements mentioned in standards about daylight in buildings but based on conventional fenestration systems. © 2020, LLC Editorial of Journal ""Light Technik"".

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.
