Abstract

Recently, the significance of human well-being in architecture has been growing. In particular, it is quite important for student educational facilities to serve as a pleasant and safe space with an efficient classroom environment. Providing an appropriate light environment and preventing excessive glare in the classroom can improve cognitive function for students, their health and academic achievement. The domestic green building rating system (G-SEED) evaluated light environment and glare control for natural lighting in the classroom through illuminance and shade standards. Still, it was not assessed from an integrated perspective, and the shade standards were ineffective for the lighting environment and glare control. This study aims to verify whether the G-SEED shading standards for creating an appropriate light environment for educational facilities were appropriate through simulation. This research established the simulation standard through a comparative analysis of the light environment, glare measurement metric, and G-SEED and LEED(USA) evaluation criteria. In addition, the range of shade length for simulation was derived through the shade length specification of G-SEED targeting general classrooms (7.5*9.0m, h=26). Based on this, the light environment and glare were simulated with the Grasshopper Algorithm based on Climate Studio. Through statistical analysis (SPSS) of the simulation results, the trend of the light environment, glare change according to the length of the shade, and the mutual statistical significance between each shade length were identified. It was derived through simulation and statistical analysis that the shade length specification of G-SEED was not statistically significant in some effects on light environment and glare. In addition, it was found that there was a need for a method to evaluate the diversity of design integrated into the currently proposed standards. Therefore, it should be developed into a green building rating system that can improve students' learning and well-being while supplementing these limitations.
