Daylighting is one of the aspects that need to be considered in the design of public elementary school classrooms in Indonesia, as it impacts the health, comfort, and focus of the students. Good daylight performance can reduce the use of electric lights, leading to energy savings. Elementary school classroom buildings in Indonesia should have optimal daylighting performance because Indonesia is a tropical country that receives sunlight year-round. However, ongoing climate change alters the daylighting performance of public elementary school classrooms to change over time. A way to overcome this problem is to change the building design parameters. One of the building design parameters that has a significant influence on daylighting performance is WWR. Therefore, designing elementary school classrooms with good daylighting performance involves varying building design parameters related to WWR, such as the size and position of openings. Daylighting performance in Indonesian elementary school classrooms can be assessed through building modeling and simulation in Rhinoceros 3D and Grasshopper software. These simulations utilize historical climate data from Climate One Buildings and future climate data from the Future Weather Generator. The results of base design simulations with year change scenarios and climate data emissions show that climate change scenarios affect the daylighting performance of public primary school classrooms in Indonesia because climate change causes the radiation and illuminance components to change. Therefore, a variation design simulation was conducted for each future climate scenario. The simulation results show that WWR is the design parameter that most affects daylighting performance in this study. After optimization of all simulation results, there is one optimal opening design for all future climate scenarios: an opening with a WWR of 15%, a window elevation of 1.5 m, a window height of 1.1 m, and a window distance of 1.5 m.
