Parameter identification with the software package LORD

This paper describes some basic concepts of the software package LORD, which was developed during the PASLINK projects. LORD allows the modelling and identification of thermal systems, in particular building components. A certain degree of experience is necessary for the correct application of the software. Although the technique used is the well-known lumped parameter modelling, which describes the thermal system as an electrical analogue RC network, several improvements are possible. One of them is the stochastic treatment of the data. Such developments of the package have produced improved results and expanded its range of application.
