Capacity Building Programs: Offering training programs for architects, engineers, builders, and contractors on best practices for sustainable construction. Monitoring & Reporting Mechanisms: Establishing systems to monitor and report on building energy consumption to track progress towards sustainability goals.

What are potential drawbacks or limitations of relying solely on machine learning algorithms for predicting building energy consumption?

While machine learning algorithms offer numerous benefits for predicting building energy consumption, there are some limitations to consider: Data Quality Issues: Machine learning models heavily rely on data quality; inaccurate or incomplete data can lead to unreliable predictions. Interpretability: Some complex machine learning models lack interpretability, making it challenging to understand how they arrive at specific predictions. Overfitting: There is a risk of overfitting when a model performs well on training data but fails to generalize accurately on unseen data due to capturing noise instead of patterns. Limited Contextual Understanding: Machine learning algorithms may not account for contextual factors like occupant behavior or weather changes that influence real-world outcomes significantly. Model Bias: Biases present in historical data used for training can be perpetuated by machine learning models if not addressed properly.
