In this paper, based on in situ experimental temperature measurements, the following dynamic thermal parameters of a wall were calculated: decrement factor, time shift of thermal transmittance and areal heat capacities. The outdoor and indoor air temperature of a resident building in Belgrade during the three months from spring to summer of the last year were collected by data loggers. The experimental data were processed using the techniques of filtering and Locally Scatter plot Smoothing (LOESS) method, in order to get frequency and amplitude of daily temperature variations. A solution of the Fourier heat equation for this case, in matrix formulation in frequency space, is given. Matrix's elements of the Fourier equation were used for calculation of the dynamic thermal parameters of the wall.
