Detailed Thermodynamic Modeling of Multi-Zone Buildings with Resistive-Capacitive Method

Increased use of energy in buildings and HVAC systems requires advanced control schemes like model-based control to improve energy efficiency, which in turn requires accurate thermodynamic models of buildings. The Resistive-Capacitive (RC) method is a popular and versatile approach for thermal model...
