ᐅ How can you bypass energy-saving regulations and avoid bureaucratic hassle?

No, because the cold air warms up within a few minutes since the house is heated... as the house is insulated, all the furniture, walls, people, etc. are part of the heating system... and everything inside is at a significantly higher temperature than the cold air from outside. So, of course, energy is needed to warm up the cold air, but this happens relatively quickly and efficiently. In a house from around 1900, you have cold walls, etc., which leads to the well-known problems.

Quick question regarding the "bold text":
I often see images taken with a thermal camera of an older, uninsulated house. These always show a bright red color (meaning warm).
However, you say that the walls of old houses are cold.
(I actually thought the same myself...).

Where am I making a mistake in my thinking?

Strange that you, as a new user, know Steffen80 so well [emoji848]

That "LOL" also has a childish tone, where do I know that from? [emoji848][emoji848][emoji848]

Hi ypg,

why is that strange?
I have already noticed that you, for example, are always very helpful and usually very pleasant and professional in tone. Sometimes a bit sharp... but still very accommodating.

11Ant is also very helpful and thankfully does not hold back his opinion and support. However, the tone can be a bit sarcastic at times.

Steffen80 is a multimillionaire and likes to make that known to everyone without being asked. If you look at almost any (somewhat exaggerated) thread about financing, you can't help but come to that conclusion. (As I said, he’s probably really nice in private!)

I could say something about some users here in the forum. (So don’t feel “ignored”!)

You probably know "LOL" from the internet or texting. I didn’t invent it. It’s been around for a long time.

Childish? Yep, hopefully, I’ll be a little child at heart for life.

Long story short. I’m not going to convince you. I’ll just tell you what’s possible with the energy saving regulations without using styrofoam or proprietary systems. A aerated concrete wall, Ytong or similar, at least 30 cm (12 inches) thick. Then plaster. Or a 24 cm (9.5 inches) thick block, some fiberglass insulation, and a brick veneer in front. A small air gap in between. Windows should be double or triple glazed, but with passive forced ventilation—look up RegelAir. In the bathroom, possibly a Maico exhaust fan, manually operated via the light switch. Hot water heating with radiators if underfloor heating feels too warm. Such a house is not completely airtight nor fully wrapped in insulation, yet it can be approved without issues by the building authority.

Hi Nordlys,
this gives me something to work with, thanks a lot.

Wood is probably still in the running as a material. May I ask how one would need to insulate if I wanted the extension made from as natural wood as possible? (Not a log house, but wooden battens).

The next question is: how does the wooden extension “work” with the existing double-walled masonry?
Is there anything special to consider?

Well, I wonder why you want to know or meet people here by reading, when maybe you should be studying insulation and related topics instead. Just trolling. A Maxximus, whatever that is. I’m out anyway – no one has ever called me snippy [emoji23]

No, only very few people say LOL here, I’ve seen it 2-3 times... it’s a phrase used by people stuck somewhere in the past, for example due to a loss... often in a relationship, but not necessarily. At least it reflects a stagnation in development... I’d guess from 5 to 10 years ago.
The age back then was in the twenties, and others rarely used this abbreviation...

Hello Farilo,

I think it’s good that you want to think for yourself about whether a solution really makes sense. However, you lack basic physics knowledge to tell if your reasoning is correct or not. I conclude this at least from many questions you have asked throughout the thread.

Hello Chand,
you are absolutely right there.

Fundamentally and upfront: It is correct to gather information from several sources. But you have to be aware of the danger of "confirmation bias." You fall into this cognitive error when you give more weight to sources that confirm your subjective feeling than to those that offer inconvenient information. So be especially careful if you find Mr. Fischer’s position "plausible"—perhaps you would see it differently if you knew more!

Confirmation bias is quite a tricky issue. I am aware of this "phenomenon" and do try to watch out for it. I also have no problem changing my opinion today if someone explains something factually and, with some luck, I understand it. But this is an ongoing struggle. I keep at it.

Regarding Mr. Fischer, I do not accept everything he says without question. But I listen. And the things I think I have understood, I take as input for forming my opinion. Just like many opinions here from the forum. When Mr. Fischer talks about climate change or presents his rather "unique" tables, that’s where I stop. (He definitely should work on the layout of some of his presentations.)

A strong counterargument, for example, is that he generalizes personal experience to the overall condition: He works against faulty insulation—so he only sees the faulty cases—and makes that a fundamental problem. In reality, this affects 0.x% of insulated properties, while professionally installed insulation performs as promised in the other 99,...% of cases. Anyone adopting such a view just because it confirms a (pre)judgment is not really thinking independently, so be cautious!

I do not want to act as Mr. Fischer’s defender here. That’s for him to do himself. But what you described above is a trait we all show. We learn from personal experience and share it with others. I don’t take it at face value when he says ALL houses have mold. At the same time, I don’t dismiss it entirely as nonsense either. At the moment, I just don’t have a final opinion on this. Field research, which will likely never happen, could provide clarity. So that remains wishful thinking.

You should also reconsider your economic approach to whether it all pays off financially. Just as an example: Depending on your property (which I don’t know), insulating the roof might create usable space where before there was only limited usability (too hot in summer, too cold in winter). In that case, you have created space that might have cost you more if bought, than the insulation itself. This could be considered a gain, even if there is no short-term payback purely from heating cost savings. Depending on how you calculate it… here too you need to be clear whether you want to include value increases (in pure money terms) and usability improvements (from uninhabitable space to potential living or good storage space) or not.

I understand what you mean. I see it similarly. There are certain added values that cannot or should not be directly compared in cash.

I hope I was able to give you some "food for thought," you still seem to be on your educational path .

You did!
Thank you.

Finally, something about the subjectively perceived indoor climate by you all. Here too, I see confirmation bias at work: With a skeptical attitude towards insulation, you visited houses, felt uncomfortable, and what was to blame then? Logically, the insulation!

However, your discomfort can have hundreds of other causes. Too bright, too dark, too much echo, ceiling too low, too high, wrong colors, not the right cozy materials, an unfamiliar smell (nothing touches our emotional center closer than smell!), no lake view from the window, unpleasant outside noise, and so on.

Especially in very old houses with original windows, there is constant air exchange with the outside. This influences, for example, the smell and might also cause a sensation of moving air. Anyone who finds this comfortable must still remember: In winter, that means heating, heating, heating. And that means not only cost but constantly heating dry winter air from outside—inside it is warm AND very dry. After a few weeks, your eyes and mucous membranes will show you what they think of this indoor climate.

Well, that cannot be the case. I did not travel across the country to visit almost every house-village just because I initially thought insulation was bad. Especially with Viebrockhaus, which usually has a good reputation, I felt stifling air in every single house. Truly every one! And that was even though sometimes the door was left open longer downstairs. (Or is that exactly the reason, and I don’t understand a deeper physical cause?)

So, I definitely did not approach the matter with bias. On the contrary. I wanted to and almost did, reluctantly. Until I got lucky and suddenly other questions had to be resolved.

I just need to write many things down in a notebook, very traditionally. I cannot remember all these information and opinions. And searching the forum every time is tedious. Pen and notebook acquired
