Building thermography - non-destructive visualization of building defects Building thermography is a non-destructive measuring method for the detection of building defects in thermal insulation and thermal bridges on buildings. The use of thermal imaging cameras makes infrared radiation visible. The principle of the thermal imaging camera is based on the knowledge that each body or component emits a different amount of heat radiation. This for the human eye invisible heat radiation, also infrared light, is made visible by the thermal imaging camera by means of sensors. This technique makes it possible to determine the smallest temperature differences in the building components.The thermal images of a building show where building insulation is leaking or where the required insulation thickness is insufficient, depending on the colouring of the building parts. The temperature differences also reveal areas where leaks or thermal bridges are present. Accordingly, clear and usable images in building thermography are obtained very well in the cooler season. The temperature difference between indoor and outdoor areas is used here. In order to obtain unadulterated images of the thermographic building envelope, it is also necessary that the facade surfaces were not previously exposed to direct sunlight. The colour images of the thermal imaging camera clearly show where the weak points are on the building, uninsulated areas appear in the red to yellow range. If green areas are predominant, this corresponds to a well insulated standard.Thanks to this non-destructive visualization of building defects, the building thermography method is particularly popular in the field of building renovation. Here it can then be planned specifically which construction measures are necessary to achieve good building insulation. Also in the area of the quality assurance method with regard to compliance with the Energy Saving Ordinance (EnEV) and the proof of certain building standards (energy efficiency house 50 or 70, energy-saving house or passive house) the photographs with the thermal image camera serve. Another field of application for building thermography is the field of blower door tests. This test in the new construction area of residential buildings provides proof of the windproofness of the building envelope and is therefore an important component of the ean50.
