Construction costs are currently skyrocketing

The obligation to energetically renovate something within 2 years after acquisition has actually existed for a long time

Although I would not call that "renovation," but rather cosmetic retouching. What needs to be done? - Insulate uninsulated pipes in unheated rooms - Insulate roof/top floor ceiling if the minimum thermal protection is not given - Replace heating if too old – although this expressly does not apply to low-temperature or condensing units In the end, it’s trivial and actually only rarely done completely. And I have indeed never seen an inspection – because no one (chimney sweep) gets paid for the inspection, so no one is motivated.

That's exactly right! There was once an inquiry to the responsible ministries of the states about how often this was checked. Most did not respond, in BaWü it was apparently 6(!) transfers of ownership. In other words: Laws and regulations must be put into practice, otherwise they are useless.

We are now getting things moving with the EU renovation. Among other things, a narrow wall is supposed to be demolished and then re-erected in a different position. A structural engineer is coming at the beginning of January. Are there any comparable values here, has anyone had something like this done and still remembers how much the structural engineer cost?

I am also extremely curious about the estimate from the interior fitter, as quite a bit is supposed to be done. Mainly interior plaster, floor insulation, underfloor heating, screed, and a few small things.

Perhaps the energy problem will soon be solved anyway, if the approach of the Lawrence Livermore National Laboratory can be pursued further, which, as some of you may already know, has succeeded in gaining more energy from the fusion of atomic nuclei than is put in. No radioactive waste was produced in the process either. It is exactly such news that gives me hope that we can solve our problems if we invest sufficiently in education, training, research, and development and do not leave too many people behind.

Read the message carefully again.

It is important that the reported energy gain basically only refers to the core of the experiment: The amount of energy directed at the hydrogen nuclei in the lab by the lasers is compared with the energy released. However, according to Roulstone, it is overlooked that almost 280 times as much energy must be expended to operate the lasers as finally reaches the hydrogen nuclei.

Translated, it means: It will still take a very long time before usable energy can be generated from it. We will probably not live to see the widespread use of such reactors.
