An application of spectral decomposition to model validation in the thermal analysis of buildings.

Summary

The authors compare building thermal behaviour as obtained from experiment and from a physical model. Experimental data are analysed by use of an identified model, decomposed as a sum of first-order models. The physical model is reduced to an equivalent form by use of its eigenelements. This method provides an intrinsic basis for comparison. Analysis showed that the dynamic behaviour of the building could only be explained by using a two-dimensional model for conduction in one of the walls; the agreement between experimental data and theoretical model was then quite good.
