Monitoring and inspection of apartment building facades with the help of thermography aims to identify and evaluate construction defects and their effects on thermal efficiency. The analysis of facade cracks is of great importance in the investigation of construction issues, especially in the rehabilitation processes of buildings. In this paper we studied the thermal rehabilitation efficiency of apartment buildings in Bucharest. The used approach was to compare the facades of insulated with non-insulated ones in two periods of time to identify defects and detailed analysis of thermographs in areas with heat losses. The study focuses on the temperature gradient, temperature variation and distribution, but also on Δ T value which is a thermographic analysis tool that shows the temperature differences between two components, being a criterion to identify and evaluate defects.
