Abstract :
[en] Reducing energy consumption has become a critical priority in sustainable urban development, with accurate prediction of building cooling loads essential for efficient energy management systems. However, challenges such as inconsistent data and model generalizability restrict the seamless integration of energy modeling into urban planning. As such, this study introduces a novel hybrid modeling framework to forecast annual cooling load intensity in Phoenix, Arizona. The proposed hybrid approach integrates Extreme Gradient Boosting (XGBoost), Light Gradient Boosting Machine (LightGBM), and Categorical Boosting (CatBoost) in a stacking ensemble and uses a GA to optimize hyperparameters and the meta-learner. The results demonstrate that this optimized framework achieved a better accuracy with a root mean square error (RMSE) of 1.09 kWh/m², a coefficient of determination (R²) of 0.99, a mean absolute error (MAE) of 0.26 kWh/m², and a mean square error (MSE) of 1.19 kWh/m². Additionally, SHAP interpretability analysis indicates the window-to-wall ratio as the most influential driver of cooling load inPhoenix, Arizona. The model’s robustness was further validated on 100 unseen buildings in Scottsdale, Arizona, demonstrating strong generalizability. These findings highlight the potential of the proposed framework to enhance building energy forecasting and to provide actionable insights that support urban energy management.
