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

but I am also not saying the moon landing is controversial, because there is a certain group that claims it is a fake

The moon landing was real, but its television version was reshot. However, that is truly OT.

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.

... or devaluation in the eyes of a potential buyer who sees the insulation material as a contaminant. Oh, how proud people were of Eternit back then.

... or inferiority in the eyes of a potential buyer who sees the insulation stuff as contaminated waste. Oh, how proud one was of Eternit back then.

Well, luckily you sleep on the floor, only sit on sheepskin in the living room, drink your milk straight from the cow's udder, and brush your teeth with miswak And with all these activities, there isn't even a thick layer of stone and plaster between you and the evil plastic

You are always so unreasonable! Insulation is not evil. But insulated old buildings often cause problems. The materials should be compatible with each other. If I wrap an early post-war house, simply built, thickly, I easily get mold spots where it stays cold/damp. You have to approach that more carefully. Maybe leave it with new windows that are no longer so drafty. Maybe improve something with glass or stone wool in the roof and in the side areas. That's it. A new building can be designed from the start so that it fits, insulated really well. But the ventilation problem remains. Either controlled residential ventilation or forced ventilation of the windows. That contradicts the insulation idea, but it is healthier. I myself refuse to buy a car whose windows are closed and that compensates this with air conditioning. I hope you understand the metaphor. About cost-effectiveness. There is a lot of malpractice with calculation tricks that do not work. I’ll give you an example: We are supposed to produce hot water using renewable energy. Okay. We are supposed to consume as little primary energy as possible, preferably very little from fossil fuels (wood stoves apparently don’t count, they seem to be eco-friendly, smile). But if - as with us - 110 sqm is inhabited by just two people who have no bathtub, a dishwasher, and a shower, the most economical and ecological would be a pure modern gas boiler with condensing technology without hot water supply. A hot water tap in the sink with an instantaneous water heater, the same in the shower, with 2 times 3-4 minutes of showering per day totally fine, only cold water at the washbasin, also in the guest toilet. End of story. Windows with forced ventilation, end. That saves construction costs, gas, and the little electricity for 2 showers is negligible. A controlled residential ventilation is omitted, more electricity saved, but the energy saving ordinance does not want such a house. It wants solar panels (which are glued together by little Chinese people who knows how), or controlled residential ventilation or air-water heat pump or geothermal or biogas district heating. But it lets the wood stove pass. For us, I am sure, what the ordinance demands is economical nonsense. And ecological nonsense too, - Karsten

Modern houses often have a .... it's too warm-feeling. And it's somehow stuffy feeling. A remedy can be. Radiators instead of underfloor heating. Walls painted with breathable paint. No gypsum plaster, but consistently lime-cement or even clay plaster. Forced-ventilation windows. Karsten

I find the clay plaster interesting. Is it applied inside instead of cement plaster? And can you then paint or wallpaper normally on it? (Sorry, I really have no idea...)

If you stay in the system, you can forget about it. With colors from Keim, for example. Google is full of how to do clay plaster. It’s expensive. Karsten
