THE ESTIMATION OF THE STATE OF BUILDING USING INFRARED THERMOGRAPHY AND NUMMERICAL METHOD

Thermography, as a contactless method for measuring temperature and temperature distribution on the surface of an object, has found its application in many human activities. On the basis of surface temperature measurement, the conclusions about the condition of the monitored object can be made. As far as the buildings are concerned, thermography plays an important role in quality control, heat losses measurement and inspection. In the paper the results of thermographic measurement, carried out during the winter and spring of 2004 on the facade of Jadrolinija Co. Rijeka main building, are given. It is a historical building, about hundred years old. The aim of the performed measurement was the estimation of the state of building and the necessity of its reconstruction. Thermographic analysis includes qualitative and quantitative interpretation of the results. Qualitative analysis was done on some characteristic parts of facade and confirmed with numerical simulation. The paper also includes a comparison between thermograms made on the same place of the facade in winter and spring period, with different boundary conditions.
