Abstract :
This paper proposes an aggregation-based model reduction method for thermal models of large buildings. Using an electric analogy, the baseline thermal model is represented as an RC-network. The proposed model reduction methodology is used to obtain a simpler (with fewer states) multi-scale representation of this network. The methodology preserves the electrical analogy and retains the physical intuition during the model reduction process. The theoretical results are illustrated with the aid of examples.
