Automatic Model Reduction in Architecture: A Window into Building Thermal Structure

Abstract: Reducing building model complexity is currently a heuristic process requiring experience and skill; little progress has been made toward a numerical framework to automate this process. This paper proposes integrating automatic model reduction into the design process using a transparent model abstraction. Resistor-capacitor network analysis, mapped appropriately to a building information model, can provide the architect with insight into thermal coupling among building elements. Experimental results demonstrate the use of model aggregation to reduce simulation time without significant loss of accuracy.
