Is there also material with fewer cm, but for example 023? We also have that on the roof. Then 2-3 cm less should be enough, right?

Ok, what could happen in the worst case?
That the parapet has to be extended? Would that be a big cost factor? Semi-detached house with 87 sqm roof area..

Yes, there is better material, PIR has a thermal conductivity of 023. Then it becomes thinner or you make a thin layer of it and EPS on top, depending on how much is needed to reach the target value. PIR is, of course, noticeably more expensive than EPS and with double labor costs these costs also become significant.
Maybe the energy consultant will also pull something completely different out of the hat. There are many options.

Parapet ... I’m not a roofer :) I would estimate in the range of 3-5k €. The downpipes might also need to be adjusted.
Your roof was just renovated, so you should know the prices.

The rainwater runs down the facade instead of dripping off. At least it doesn’t look nice.

Attached are pictures of my facade. I think, apart from the cracks, it still looks great, doesn’t it?

So if I plan to only paint/repair the facade until retirement, how should I proceed?

Just paint with crack-bridging paint?
Can I leave the cracks as they are for now?
Can the ETICS be damaged by the existing cracks? Keyword moisture?
What happens if the plaster flakes off, especially in the area of the cracks? Is it sufficient to just repair it in those spots?

My concern is: what can I do now to keep the facade as it is without expensive renovation?

You can do that.

A clear yes and no. Only plaster cracks in the topcoat? Then you can leave it like that. If the cracks go all the way through to the ETICS, you already have a moisture problem.

Yes.

Superficial cracks = do nothing or paint (appearance)
Deep cracks = get a painter/plasterer who can offer a solution (partial repair)

How can I check if the cracks go to the WDVS? If yes and moisture has already penetrated, is it enough to remove the plaster around the crack and replaster? Or is the WDVS then ruined? And if yes, can the WDVS be renewed at that spot or does the entire façade have to be renovated?
