How can one circumvent the Energy Saving Ordinance and avoid bureaucratic madness?

No, I have to agree with you there. At the latest yesterday evening, I also thought he can only be trolling.

Sure, it's a troll, but the topic is still interesting.

And you take this guy seriously?

Come on..

If it's a troll, the direction it comes from is clear. The name of a certain gentleman has come up conspicuously often.

Nevertheless, everyone gets a chance... the topic, as I understood it, is interesting regardless of trolling: "Is insulation worth it?"

"Worth" has an ecological and an economic dimension, plus the subjective feeling of living associated with it.

And even the ecological component, although the toughest category in the whole story, is controversial. So here you have a topic that is certainly not settled (okay, maybe it never will be).

You forgot the esoteric component, which plays the biggest role in the topic of insulation, meaning the argument "walls can no longer breathe" or "plastic is evil"....

The ecological component is not controversial... ok sure, if you take the often mentioned gentleman here, but I also don't say the moon landing is controversial just because there is a certain group claiming it's a fake or that 9/11 was a staging by the USA. Even the disposal "problem" that was so heated just a few months ago has dissolved into thin air in a very short time.

The economic one is of course controversial because no one can predict the future and price development. If you don't assume rising energy costs, you can't calculate insulation economically. Who is right will be seen in many years.

The ecological component is not controversial...

Not? I have already heard that the production, transport, and installation of insulation require more energy than it can save during an average lifespan. That is calculable nonsense, but I have heard it anyway.

Anyone who does not assume rising energy costs cannot calculate insulation economically.

And that is why the economic discussion is controversial: That may be true if you only compare the future costs of saved heating energy against the price of the insulation. But that is only half the story. Insulation contributes to the value of the house and is thus tied-up capital—not just money spent.

Anyone who argues as you do has removed the house value from their private balance sheet and only looks at the flow figures (e.g., how much I spend on heating and how much less that is with insulation than without). The stock figures (such as the house value) are ignored. But that is incorrect. The economic monetary value of the insulation is the money saved on heating/cooling energy PLUS the added value of the property attributable to the insulation.

I haven't calculated anything concrete at all?! Of course it increases the value of the house and of course that must be taken into account in the calculation, but it does not change the fact that the future development of energy prices is the big unknown that you can manipulate at will.
