    Comparison of Advanced Daylighting Systems To Improve Illuminance and Uniformity Through Simulation Modelling
    (Znack Publishing House, 2014) Kazanasmaz, Zehra Tuğçe; Fırat Örs, Pelin
    Deficiencies 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.

    Illuminance 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 Tuğçe
    Uncontrolled 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.
