Building without a ventilation system using hollow bricks?

Hello kamnik,

astonishing how much anger you wield here with the (conspiracy) club. Take it like the Buddhists of your part-time chosen home: No claim to absoluteness on your own religion.

We would like to support you, but unfortunately your statements completely miss the topic of the questioner. My tip: Start your own topic where all debaters can discuss your theses!

I found Fabian’s original question more interesting than your comments.

Hello kamnik,

amazing how much rage you wield here with the (conspiracy) cudgel. Just do it like the Buddhists of your part-time adopted home: No claim to absoluteness for your own religion.

We would like to support you, but unfortunately your statements completely miss the questioner's topic. My tip: Start your own thread where all willing debaters can discuss your theses!

I found Fabian's original question more interesting than your remarks.

The problem is that communistically oriented people like to psychiatrize dissenters when they run out of arguments? In the whole follower generation, it is always difficult when others think and act against the current. In sports, one would say: not very sportsmanlike.

But you have to take all that lightly.

ps. stock up on 10 x credit cards, get 2 x mortgage bonds notarized into your land register excerpts, pay until retirement... but don't complain in retirement: "...there was no money to live on..."

Basically, only the 3 B's matter: Beer, babes, bikes!

This is a - planning tailored to a specific life situation -; you copied the views from the front page of my homepage in the single-family house section. These views are an example of a cube.

Great sales argument? respect!
tailored to a specific life situation (I have to remember that)
If there were lime cement as plaster on the walls, I would find this construction method extremely negligent towards the builder.
This reduction of the roof overhang has cost many owners new windows in the Munich area + surroundings.
Reason: Due to leaching out of lime materials, lime residues deposit on the glass and eat into the glass surface. An action that would be avoidable if the district offices + building authorities had left another construction option open - but the builders were not allowed to do so - similar damage that cannot even be reverted because the magistrates are now in retirement homes (due to Alzheimer’s) and no longer accountable.

Especially many of your "old" masters have produced this dangerous nonsense. By the way, just like their "estimates" of the heating energy demand of a single-family house. I know enough of them and "owe" them quite a bit of extra and unnecessary work. Currently, again one of your old "masters" decided on short notice to install a 3 kW higher heat generator - better safe than sorry. Apart from the fact that it is completely unnecessary - the heating load calculation confirms the sold heat generator, it would have cost my clients 5 to 6 thousand euros more. So much for the subject of "old masters"

What does a 3 kW higher heat generator mean? Which heating system was installed, what is the output of the system?
Heating is generally a science. At trade fairs, every manufacturer also says: "My system is the best - never had any problems," etc.
yeah, yeah
Gas condensing boiler + proper control (+ remote function; i.e. worldwide access to the boiler)
Domestic hot water: AEG eco boiler for shower + sink (then you also get boiled water and not some contaminated puddle from the 1000-liter storage tank which is completely emptied every 2 months + circulation pump power for nothing).

Here is a commentary on the flat roof guideline for interested laymen:

"Since October 2008 the new flat roof guideline
that the technical rule is also responsible for
waterproofing against non-pressing water. However, with the condition that
DIN 18195 is also to be observed here, which is expressed under item 3 Rules for waterproofing
of utilized roofs and surfaces."

Flat roofs are always sources of trouble. All flat roofs are generally roofed over; with wood or steel construction.
Anyone who has already had flat roof repairs certainly doesn’t want flat roofs. Wherever the
mud sits in the corners, moisture eventually bores through the underlying layers.
No DIN helps you there; only good business liability insurance for the front-line worker.

If the respective builder uses "Douglas fir" instead of spruce and maintains his facade, this statement is irrelevant. But - and here we are back with you - Douglas fir is, of course, more expensive

persistently high moisture, so that a pressure impregnation is necessary."

? how do you want to maintain a vertically nailed facade at 5 meters height after 5 years?
aa) erect scaffold
bb) remove battens, sand, oil or impregnate them with a compressor.

? how else do you want to get behind the battens?
my personal opinion: a miserable brain fart from planners without much thinking.
Otherwise you can’t call
this misplanning. Then without roof overhang, so that lots of
water runs down the walls and lets the material weather even more.

If you mounted vertically overlapping boards as was regularly done in the past, you could spray facade protection paint with a compressor every 5 years and have peace for the next 5 years?
But instead, you screw obsolescence material to the wall that dies after 10 years.
Then buy new.

I cannot understand how one can still give prices for such things?
Review:
aa) No overhang/roof, to save material
bb) vertical battens on the facade, so you have work again after 10 years?
cc) flat roofs, so that construction damage occurs after a few years
dd) cube + barn shed shapes, with side sliding doors for the 4.5 x 2.8-meter sliding glass window elements (main thing: expensive + complicated)
ee) additional awning technology for the large-area windows, so you don’t get heat stroke in the living room with direct sunlight
ff) overpriced air conditioning technology so you can expel the heat again when the
Osram (lamp) is properly at zenith
etc. etc. etc.

There is a petition committee - also in Brussels. Ask your questions there!

Not all, that's true - I still preferred the very old church or cathedral builders to the "old masters or master builders" you generally praise

Petition committee? oh well; what applies: total refusal and just say no.

The original couple built their house themselves more than 80 years ago, dug the cellar by hand + rotated the return corner in the gable 90 degrees (not many can do that today) and it still stands.
Their daily business: they had nothing to do with construction, more with steel.

The construction industry today has become so unimaginative? What really pisses me off as a baroque type: these straight lines in today’s modern architecture - so boring.
I prefer the Arab world, because they still have imagination, except in the slave state of Dubai.

I simply recommend everyone here to use the ignore function... it works great.

Stand in a prefabricated house in summer and then in a brick house, at 40 degrees Celsius outside temperature, in summer.
In the prefabricated house, the heat accumulates, which has to be transported outside via an overpriced air conditioning system.
In the brick house, I don’t even have this problem because the brick cools sufficiently.

Kamnik, you have probably experienced that a brick house was cooler in summer than a prefabricated house you stayed in...
However, drawing general conclusions from this is not particularly helpful...

There are certainly prefabricated houses with poor summer heat protection... but you can also achieve good heat protection in a prefabricated house!

By the way, the brick does not cool... it absorbs the heat, heats up slowly, and thus delays the penetration of heat into the interior... in the evening/night it then slowly releases the stored heat again. If you have an insulation layer in front of the brick, the heating up is additionally delayed.
The ideal combination is therefore an insulating layer, which, however, can hardly absorb heat due to low mass, followed by a heavy layer with high storage capacity... e.g., brick or massive wooden boards, plasterboard, etc... the thicker the better...
Many cheap, old prefabricated houses often saved on the mass here, which is why they sometimes had poor heat protection.
Much more important regarding heat protection is shading of windows! Through a window, on a sunny day, so much heat enters the room that the wall hardly matters anymore...
Especially older buildings sometimes have very small windows compared to modern (prefab) houses. If these are not properly shaded with external sun protection, I will have problems!

Prefabricated houses therefore do not need air conditioning if properly planned, just like solid constructions...

That is the popular misconception. People open the windows in winter because their throat is scratchy and they are suggested that the oxygen must be depleted.
This is exactly where the problem lies.
The problem is that the heating consumes the humidity in the room. Then the scratching/discomfort in the throat comes, then you throw the windows open.
By placing small humidifiers, I get enough humidity in the room and don’t have to constantly throw open the windows – because the oxygen level is often sufficient.
But it also depends on how you heat. If the Chief/Bullerjan (type of stove) burns oxygen in the volume, I have to add; but this works with a very small control, an intake air duct + fan, without having to throw open the windows.

Again: This applies to your old building with a combustion source inside the house... not to a new building! Here you do not have the problem of too dry air if you have no ventilation system... the opposite is the case!

I transfer a lot from building technology from the year 1980 to today.

And here lies your problem... Today’s houses are simply not directly comparable here anymore... Whether you like it or not is another matter...
It is simply a fact that houses today must be well insulated and almost airtight!

If you now just apply old approaches to new houses, you get exactly the effect that nothing fits, everything is sh** and you start to rave about the good old days...

But people are becoming more and more soft? Just camp outside in winter once, that makes you tough + wash your genitals in the morning with cold sea water + normal soap?

You complain about the extra costs but do not want to acknowledge the advantages... with the same argument I could ask you why you have electricity and running water or buy clothes etc... you could camp in a tent in the garden, that is by far the cheapest!
Calling others soft but flying to Thailand every winter yourself...

When I already read nearly airtight house, my alarm bells ring.
... there have been wall ventilators since the 70s, even exhaust devices are standard for cooking areas?

?
What alarm bells are ringing there? That is simply how things are nowadays... and now you come with wall ventilators and exhaust devices? I thought you were against fans etc...
What now?

The bigger problem is the total insulation. The local expert reports miserable mold infestations... not in old existing buildings... no, mainly in renovated buildings, which have been totally insulated with super windows + ultra insulation. No air gets through, people want to save and then boom, mold in the house

Exactly! That’s what we’ve been writing all along... well insulated house -> ventilation system...
That’s why the original poster asked... and you were the one who told him a ventilation system is unnecessary etc...
Then he would have exactly the described problem... The house no longer ventilates itself through cracks and gaps and leaky masonry/windows but must be ventilated manually or by controlled living space ventilation much more often...

So what are you trying to tell us now? That your initial views were dangerous nonsense and the original poster should please plan a ventilation system if he doesn’t want to live in a mold farm soon?

Conclusion: A low energy house only pays off for the planner because he can skim off money.

Whether and when it pays off is secondary... the fact is that today you have to build such a house!
So it does not help the original poster if you give him advice based on "high energy houses" just because you personally don’t believe in low energy construction...

Or did you just want to spout your pub talk and only used the original poster’s topic as a hook?

Hello everyone,

thank you very much for the good advice.
I will now plan my house with a ventilation system. The window vents also sounded interesting.

P.s. it's a pity that so much was written off topic here. I am not interested if someone here has a basement with 400m² and 20 cars. I believe that was not my question?

best regards Fabian
