Abstract: This paper presents an experimental and numerical characterization of the thermal behavior of the Environmental Test Chamber at Concordia University. This characterization is performed using frequency domain techniques, based on the analysis of building transfer functions. The frequency domain model was developed from the application of first-principle heat transfer equations, and then validated and calibrated with experimental data. This paper also presents a modified least-squares curve fitting method (based on an existing technique) used to obtain transfer functions from discrete frequency responses. Data not readily available in the experiments and required for the development of the frequency domain model was calculated with a lumped parameter finite difference model (LPFD).
