Abstract: The building envelope makes the most significant contribution to the reduction of building energy consumption. The application of new, alternative and improved materials and systems has an important impact on the performance of buildings. This paper is focused on thermal transmittance as an indicator of thermal conduction of the construction element. It includes comparisons of the U -values calculated by software with those measured in-situ on three representative façade walls. The walls have been constructed with the new wall system Fragmat NZ-1, a new product in Macedonian buildings. This research provides basic information on the thermal transmittance of the system. The results of the analysis show that in-situ measuring is a useful tool in validating the precision of analytically calculated values, since it was difficult to obtain precise results from the analytical calculations only, especially when the layers have non-uniform thickness.
