摘要

Conduction transfer functions (CTFs) are widely used to calculate conduction heat transfer in building cooling load and energy calculations. They can conveniently fit into any load and energy calculation techniques to perform conduction calculations. There are three methods: the Laplace transform (LP) method, the state-space (SS) method and the frequency-domain regression (FDR) method to calculate CTF coefficients. The limitation of methodology possibly results in imprecise or false CTF coefficients. This paper investigates the accuracy of the three methods applied to the material properties of a single-layer and a multilayer heavyweight building construction.
