Parametric Sensitivity Analysis of a Test Cell Thermal Model Using Spectral Analysis

摘要

The paper deals with an empirical validation of a building thermal model. Weput the emphasis on sensitivity analysis and on research of inputs/residualcorrelation to improve our model. In this article, we apply a sensitivityanalysis technique in the frequency domain to point out the more importantparameters of the model. Then, we compare measured and predicted data of indoordry-air temperature. When the model is not accurate enough, recourse totime-frequency analysis is of great help to identify the inputs responsible forthe major part of error. In our approach, two samples of experimental data arerequired. The first one is used to calibrate our model the second one to reallyvalidate the optimized model.
