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

Well, I wonder why you want to get to know the people here or why you know them by reading, when maybe you should be studying insulation and such instead. Just trolling. Some Maxximus, whatever. I’m out anyway – nobody’s ever called me snippy before [emoji23]

No, 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 because of, for example, a loss... usually in a relationship... maybe, but not necessarily. At least there is stagnation in their development... I’d guess from 5 to 10 years ago.
The age back then was in the 20s, others rarely used this abbreviation...

I find that quite surprising. After all, it’s a word that older people definitely use as well.
When? Well, for example, following your comment above.

Regarding "stagnation of my development": ypg, please, a bit more decorum and respect. Being funny and being rude aren’t the same. Watch out.
Thank you very much.

Best regards

Quick question about the "bold text":
I often see images taken with a thermal imaging camera showing an older, uninsulated house. It always appears bright red (meaning warm).
But you say that the walls of old houses are cold.
(Which is actually what I always thought too...).

Where am I making a mistake?

The walls in the images only appear red because the rest is deep blue. It only makes sense to use a thermal imaging camera when the outdoor temperatures are low. This way, the temperature differences are easier to see.

Otherwise, due to missing insulation, the wall is naturally cooled from the outside (at low temperatures). As a result, the temperature on the inside surface of the wall is a few degrees colder than the indoor air temperature.
This creates a feeling of coldness near the wall or it may even feel drafty.

In insulated houses, the wall temperature is roughly the same as the air temperature. Because there is no cold feeling, it seems warmer in direct comparison despite the same air temperature.
It simply feels more comfortable.

To compensate for this, the temperatures in uninsulated older buildings are often set higher.

There is also a certain heating behavior involved, but that would go too far here.

You can also notice this with older, large windows. Maybe pay attention to this during winter.

As a multimillionaire, I definitely wouldn’t build a house here or be active in this forum.

Did my post come across as "envy"? Hm... I actually don’t know envy. Maybe I’m wrong and you’re not a troll. Having a lot of money plus a lot of time is certainly possible, no question. I don’t know anyone personally, but if you’re that lucky, then it’s truly something to be admired.

A plot by a lake near Hamburg for 100,000 euros… I’ll only believe that once I’ve seen it. Sorry.

The mistake is this: The red color you see represents heat on the outside. But heat should not be on the outside; it should be inside. The heat visible on the outside means it is missing inside and must be reheated. Well-insulated façades appear as blue as possible in thermal images, blending with the surroundings, because the heat stays inside.

If you look at two people side by side in winter with a thermal camera—one naked, the other wearing a coat—who appears red, who does not, and which one is actually cold? Exactly...

The misunderstanding is this: The red you see is heat outside. But heat should not be outside; it should be inside. What is outside is missing inside and has to be compensated for. Well-insulated façades appear as blue as possible in thermal images, like the surroundings, because the heat stays inside.

Since the question about the thermal camera, I’m certain he is a troll.

No one can seriously engage with this topic and fail to see the logical connections xD

I’m out of this thread
Don't feed the troll

Hello Joe,
I’m not quite sure I understand that. The goal is to get a comprehensive overview, not just information from a specific time period. So why only show that one image?
Wouldn’t it make sense, in principle, to also see that there are no temperature differences?

This creates a "cold feeling" near the wall or it can even feel drafty.

Cold outside → uninsulated wall gets cold. That’s understandable.
The inside surface is then colder than the room air temperature, which explains the "cold feeling." Okay.

So this means the uninsulated wall absorbs and releases the ambient temperature. The speed at which this happens is another matter… but so far, so good.

Okay. The inside surface basically remains unaffected by the outside temperature, whether it’s warm or cold outside—completely thermally insulated.
The result is always an inside surface temperature that is roughly constant relative to the indoor air temperature.

By contrast, the uninsulated wall always reflects the current outside temperature. In other words, the wall transmits the outside temperature.
