Is the transfer function method reliable in a European building context?

Beccali, Giorgio; Cellura, Maurizio; Brano, Valerio Lo; Orioli, Aldo February 2005 Applied Thermal Engineering, vol 25-2 and 3, p. 341-357 The available tools for dynamic simulation of the buildings thermal behaviour are manifold, and the most modern ones, known as TRNSYS, are founded upon the use of the Z-transform (ZT) set also called transfer function method (TFM). The transfer function method (TFM), recommended by American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), is one of the most modern tools available to solve heat transfer problems in building envelopes and environments. TFM utilises Z-transforms to solve the equation system that describes the heat transfer in a multi-layered wall. Due to an analogy with an electric circuit, it is possible to write the equation system in a matrix suitable to be solved by computer. The authors have investigated TFM mathematical features, especially concerning the reliability and the quality of the thermal dynami
