Background: The integration of smart technologies into modern facilities has underscored the need for proactive maintenance strategies to minimize unplanned equipment failures and enhance operational efficiency. Traditional maintenance approaches, including reactive and time-based preventive maintenance, often fall short in dynamic building environments. Predictive maintenance, driven by machine learning (ML) and Internet of Things (IoT) sensor data, offers a data-driven solution to anticipate equipment failures before they occur. Methodology: This study proposes a comprehensive machine learning framework for predictive maintenance in smart facilities, evaluated using the ASHRAE Great Energy Predictor III dataset—a real-world benchmark containing operational data from diverse building systems. The framework compares both classical machine learning (Random Forest, XGBoost) and deep learning (LSTM) approaches to address different predictive maintenance scenarios. Data preprocessing included outlier removal, missing value imputation, feature engineering, and normalization. Model evaluation was conducted using precision, recall, F1-score, ROC-AUC, and inference time metrics. The system is designed for seamless integration with existing Computerized Maintenance Management Systems (CMMS) to ensure practical deployment. Results: Among the models tested, the LSTM network achieved the highest predictive performance (F1-score: 0.89, ROC-AUC: 0.93), while XGBoost provided an optimal b...
