The Conduction transfer function (CTF), which is widely used to calculate conduction heat transfer in building loads and energy calculations, is the basic method in EnergyPlus.
Could someone tell me if we can consider this method as an analytical one and if we can use the results provided by EnergyPlus for the validation of other methods?
I send you a paper "Investigation of the Accuracy of Calculation Methods for Conduction Transfer Functions of Building Construction "
This paper investigates the accuracy of the three methods applied to
the material properties of a single-layer and a multilayer heavy weight building construction.
Wait a message!
Thanks to Pr. Benouaz and Pr. Xinhua for their prompt answers.
However, in the paper :
"Applicability of calculation methods for conduction transfer function of building constructions, International Journal of Thermal Sciences 48 (2009) 1441–1451,
Xiang Qian Li, Youming Chena, J.D. Spitler, D. Fisher "
the authors considered the CTF solution as a numerical one and compared it to an other exact analytical solution.
That's why I have asked this question.
CTF in EnergyPlus is solved by the State Space technique which is a matrix algebra model, and hence can be considered numerical
