Infrared thermography applied to the amalysi of the facade openings

Energy efficiency has become one of the most important challenges facing the construction sector. The envelope of the building, considering as such: facades, roofs, holes, walls against terrain and slabs, is the object of study in multiple investigations that try to find the most efficient constructive solutions that allow to reduce the energy expenditure and CO2 emissions [1]. Among all the elements described above, the facades occupy the most important position, since if we manage to reduce the transmittance through them, the demand of the building decreases as well. The facades must be designed with the intention of isolating as much as possible our buildings from outside and complying with the requirements of the Technical Building Code. Infrared thermography has been increasingly used as an inspection technique to identify and map façade defects and their severity. The use of hygrothermal simulation to understand the dynamics of heat flow allows us to observe significant references that can help in the interpretation of thermograms under different heating or cooling conditions [2]. The detection of thermal bridges and the quantification in real time of the heat flow lost through them becomes crucial when proposing solutions that allow improving the efficiency of the building. There are many studies that address these measurement techniques, some have even tried to compare the effectiveness of current fluid dynamics simulation programs with real measurements taken with thermal imaging cameras, in order to validate the solutions proposed in the studies comparing them with measurements in situ
