Building Envelope Design Optimization of a Hypothetical Classroom Considering Energy Consumption, Daylighting, and Thermal Comfort: Case Study in Lhokseumawe, Indonesia

This study evaluated the building performance of a hypothetical elementary school classroom considering its annual energy consumption, daylight criteria, and adaptive thermal comfort in Lhokseumawe, Indonesia. Variations in building materials, construction, and horizontal shading features were evaluated for the most optimal design solution. The aim was to optimize the multi-performance criteria as an integrated sustainable design solution for a typical classroom in Indonesia. To achieve this objective, the study utilized a computational simulation method using Rhinoceros, Grasshopper, and Ladybug Tools platforms. The optimization was conducted with Galapagos, an engine based on a genetic algorithm. The results suggest that the optimal solution achieved 100% sDA300/50% and more than 96% UDI100-3000lx. The annual thermal comfort percentage was also increased to over 90%, while the energy consumption was reduced by 20% compared to the baseline design.
