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.}, school = {北九州市立大学}, title = {The Effect of L-Shaped Mini-Louvers for Building Facades on Indoor Environment and Cost in Hot and Humid Areas}, year = {} }
