Estimation of temperature transfer function in facade wall heat transport

Abstract

This paper is presenting a method for temperature transfer function (TTF) estimation by filtering an experimentally collected data. The experimental data were obtained in simultaneous measurements of inside and outside temperatures variations during the period of 3 months of a building located in Belgrade, Serbia. The TTF estimation is based on Wiener filtering technique for the dynamic systems with finite impulse response (FIR). TTF is derivate in time and complex domain and the correctness of the acquired transfer function is tested on the new input data set. The estimated TTF in complex domain is used to get decrement factor (DF) and time lag (TL) between the temperatures.
