Daylighting performance with courtyard design variant on occupant wellbeing in a tropical climate

Abstract

In a tropical climate, the abundance of natural daylighting can illuminate an internal space, and it is an effective passive design strategy that provides energy savings for buildings. natural daylighting was widely used in all building settings before the innovation of artificial lighting, due to this innovation most buildings have transitioned and adopted artificial lighting to illuminate the interior of the building. due to this, high dependency on artificial lighting causes a poor indoor environment for user health and an increase in energy consumption in the building. a courtyard is a universal design element that has been practised for thousands of years globally. its design has become an area of interest in the tropical climate, which improves daylighting performance in buildings. courtyards with a proper design are key in providing sufficient daylighting for the indoor environment, as well as major energy savings in electric lighting. this research aims to explore the daylighting performance with courtyard design variant on occupant wellbeing. the objective is to identify and evaluate the courtyard design variant and the impact of the daylighting performance done toward occupant wellbeing. the methodology used in this research is the comparative analysis method which analyses the simulation data result that produces the recommended courtyard design, which is optimum for the occupant wellbeing in daylighting performance. the daylighting performance studies are done using sketchup and velux daylight visualizer software. the result from the findings will provide the optimum courtyard design variant and daylighting performance for occupant wellbeing. the result of the finding will contribute as a guideline for courtyard implementation in a tropical climate for occupant wellbeing.
