This study evaluates and optimizes daylighting performance in a hypothetical classroom located in Lhokseumawe, Indonesia. The classroom daylighting performance is represented by the metrics aUDI 250-750lx , sDA 300/50% , and ASE 1000,250 . Under the baseline conditions, poor daylighting performance was revealed as indicated by a low aUDI 250-750lx value and a high ASE 1000,250h value. To obtain good daylighting performance, this study utilized a computational simulation method using Rhinoceros, Grasshopper , and Honeybee Plus platforms. Optimization is conducted using Opossum with the RBFOpt algorithm. The optimization result suggests the building envelope design parameters and external shading device design which results in a better natural lighting performance as indicated by the increase of aUDI 250-750lx value at about 45%, the sDA 300/50% value remaining at around 94%, and the ASE 1000,250h value has decreased by 14% compared to the baseline condition of the classroom.
