System-Theoretic Models for Building Thermal Analysis

A method for computer simulation of thermal analysis and energy consumption in buildings is described. This method is based on the system-theoretic approach which has been used to formulate and solve the set of equations for dynamic thermal analysis of buildings. The technique is well suited for computer formulation and the solution of repetitive structures. The resulting set of equations is sparse and can be solved very efficiently on a computer. The algebraic-differential equations are derived for an example using the system-theoretic approach. A large scale example is also presented.
