Buildings are mainly designed to be underpressured compared to the outside air, so that the inside air humidity cannot create microbes and other damages to its foundations.

So, the difference between a "planned" heat leak versus an abnormal leak has to be recognized.
The following circumstances have to be acknowledged before and during thermal imaging:
