Industrial sites extended over decades
On older industrial sites a brick or steel-frame hall with later extensions is common. The joint between old and new sections tends to form a thermal bridge, and the heating system has often been changed more than once. There the camera shows not only envelope defects but also old, uninsulated or wet heating pipes.
For smaller manufacturing and assembly workshops the Quick diagnosis (up to 1,000 m²) is usually enough: a fast, costed loss list that shows what pays off first.
