Abstract
This paper is concerned with identification of thermal static and dynamic characteristic values using measured data. A building thermal behavior is expressed as a mathematical model for a system on the basis of several inputs and a single output signals. The determination of system parameters is based on a simple least-squares technique. This system identification method is applied to the measured data about air conditioning equipments, outdoor and indoor thermal environments of an office building, and the calculated extraction load using identified values of the system parameter corresponds with measured extraction load well.
