Design Optimization for Light-Shelves with Regard to Daylighting Performance Improvements in The Tropics

Different daylight device systems and control strategies can be employed in different parts of a window system to perform functions, particularly for fully glazed façades. A light-shelves with parametric both portions the were proposed this study as an innovative daylighting improve distribution glare probability. The aim article was present simulation investigate influence light shelves on performance improvements buildings located tropical climates. Multi-objective optimization method by classifying results based sky conditions. metrics Useful Daylight Illuminance Glare Probability used evaluate compare final solutions blight shelf parameters shelf. concludes that optimal provide best range visual comfort office spaces tropics. idea (inner outer) provides most options achieving balanced levels front back room.
