Abstract：The incorporation of skylights significantly improves indoor natural lighting uniformity and illuminationlevels.Additionally，theuseofanairlayer helps mitigate hear transfer between indoor andoutdoor environments，thereby improving the overall quality of the indoor light environment. Using a comprehensive market building in Handan Cityas acase study，this research designs adouble-layer skylight transmissionsystem comprising 27 combination configurations by integrating skylights and air layers through the Grasshopper simulationplatform.With the helpof Octopus，amulti-objective optimizationsolution is developed to balance energy consumption and light comfort.The independent variables and evaluation index datasets are further analyzedusing the Hiplot platform to evaluate correlations between design parameters and light environment indicators.Results show that the optimal configuration is achieved when the air layer thickness is 0.8m ，thesemitransparent material thickness is 0.005m ，and the skylight area ratio is O.3.Under these conditions，the proportion of indoor effective daylight illumination increases by 10.97% ， the probability of daytime glare decreases by （204号 39.40% ，the brightnes ratio between north-south entrances and exits and their background surfaces decreases by （20号 61.45% and 45.10% respectively，and energy consumption per unit area is decreased by 18.42% . Correlation analysisrevealsthatinterlayerheightisnegativelycorelated withdaylightcoefficient，effectivedaylight illumination，and daytimeglare probability，although these correlationsare weak.The skylightarearatio is negatively correlated with indoor effctive daylight illumination，while the thickness of the interior lighttransmiting panel is positively and strongly correlated with daytime glare probability.Finally，the system's economicviability，applicability，and feasibilityare analyzed，offering anovel design approach and component model for enhancing the indoor light environment of large-scale public buildings in urban setings.
