Sažetak
The aim of this paper is to show a new possibility for in situ U-value determination using infrared thermography (IRT) method and its comparison with heat flux method (HFM). It also gives procedure for conducting the experiment and for the analysis of measured data. Average method and dynamic method given in ISO 6869 were used for data analysis, and results obtained using dynamic method show higher level of accuracy than ones obtained by average method. Results obtained using IRT method are much closer to theoretical values with differences between 0-19% respectively of the method used to approximate surface heat transfer coefficient. Since dynamic method is much more sophisticated than average method, its procedure had to be implemented using Excel VBA. The main conclusion was that use of infrared thermography could be used, together with dynamic method of analysis, for relatively fast and accurate in situ U-value determination.
