Abstract：Atrium design significantly influences the energy performance of public buildings，especially in climate-sensitive regions.This study developsaparametric optimization framework integratingautomated modeling，large-scale simulation，and meta-sampleanalysis to evaluate the impact of eightatriumdesign parameters on energyuse.Abenchmark model libraryof 39，202atrium configurationswas constructed to assess heating，cooling，and lighting energy consumption.Sensitivity analysis revealed thatatriumarea and internal opennessare the most influential factors for cooling and heating demand.South-facing atriums consistently showed lower annual cooling energy demand （CEUl） and annual heating energy demand （HEUl）.One actionable strategy is reducing internal openness （Int） and increasing external openness （Out） to significantly lowerenergy use.Multi-objective optimization demonstrated up to 40.29 % reduction in annual total energy demand （EUl）.The meta-sample model， validatedagainstfull-samplestatistics，achieved 87.6% computational savingswithmaximum output errorof only 0.35% .These findings provide quantitative design guidance for early-stage atrium optimization and enable fast integrationwith parametric BlMworkflows.
