The estimation of the state of building using infrared thermography and numerical method

Infrared 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 of building envelope. In the paper the results of thermographic measurement, performs of a building representing national heritage are given. The aim of the measurement was the estimation of the state of building facade and the predicting of the works for its reconstruction. The building is located in Rijeka, a city on the Adriatic coast and the main Croatian harbour. Thermographic analysis includes qualitative and quantitative interpretation of the results. Qualitative analysis was done on some characteristic parts of the 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.
