Multiobjective Optimization of Double‐Skin Façade Performance Using XGBoost and NSGA‐II in Buildings Under Hot Climate Conditions

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Buildings account for ~40% of global energy consumption, with cooling loads dominating in hot and arid climates. Double‐skin façades (DSFs) represent promising building envelope technologies for energy efficiency enhancement, yet standardized optimization methodologies for such climatic conditions remain limited.
