蒸暑地域おける建築物のファサードに使用するL型ミニルーバーの室内環境及びコストに与える影響に関する研究 The Effect of L-Shaped Mini-Louvers for Building Facades on Indoor Environment and Cost in Hot and Humid Areas アレクサンダー, ラニ　スルヤンドノ 1095 daylight cooling energy simulation L-shaped mini-louvers simple payback period 北九州市立大学 博士(工学) The problem of cooling energy consumption growth occurs globally. Indonesia is one of the areas which show significant increase of cooling energy demands. Focusing on Jakarta, Indonesia’s capital city, proposed shading devices were simulated to show their performance to improve daylight and reduce cooling energy consumption. The shading design is inspired by Japanese koshi, but using L-shaped aluminum profiles as mini-louvers. The environmental benefit is obtained from improving daylight condition and saving the cooling energy. Several simulations were executed. Attaching L-shaped mini-louvers at the window can lead the Useful Daylight Illuminance (UDI) to be more than 90. The comparison between electric saving and application cost shows the simple payback period of the simulated sun shadings. Placing the 15 mm × 15 mm L-shaped mini-louvers in the east and west can meet the simple payback period less than a year in both residential and office. doctoral thesis 2021-12-24 VoR application/pdf 甲第167号 https://kitakyu.repo.nii.ac.jp/record/927/files/(KKDE1167AS)甲第167号_アレクサンダー　ラニ　スルヤンドノ.pdf https://kitakyu.repo.nii.ac.jp/records/927 eng open access
