I’m just going to join in on this thread. I’m going to renovate a house built in 1973. It was constructed with concrete blocks. I basically just want to replace the windows and insulate the roof structure. Or would external insulation make sense for concrete blocks? (The heating is oil and a wood-burning stove)

I find your undifferentiated generalization even more incomprehensible...
There is a potential here to conceal an administrative offense—which can be penalized with fines up to €50,000 (approximately $54,000)—through such statements. The legal situation is a fact and cannot be broadly dismissed by referencing exception clauses.On what basis do you conclude that he has to insulate the exterior walls? That is not stated in the law. He does not have to modify the house walls at all. He can simply replace the windows, and according to Annex 3, he only has to meet certain requirements regarding the new windows. The same applies to the heating system.
