In this paper, results of a long term (30 days) experimental in-situ measurement of air temperatures and heat fluxes through a building wall surfaces are presented. Indoor and outdoor measurements were carried out simultaneously in a residential building located in Belgrade, Serbia. The data were used to calculate the thermal transmittance of the wall according to ISO 9869-1:2014. The U-value obtained from the experimental data and those calculated in steady-state temperature regime are compared. Criteria for the data that have to be met in order to get accurate U-value are discussed. The U-value obtained from the experimental data and those calculated in steady-state temperature regime are compared. The U-value of the facade wall is 18.16 % higher than that design standard in steady-state conditions. For this reason, the in situ U-value measurement is an important auxiliary measure to guarantee the actual thermal insulation of building envelopes.
