Massive passive house as bungalow

Well, concrete is not that trouble-free after all.

Small excerpt from Wikipedia:
The following damage mechanisms can occur:

[*
Reinforcement corrosion due to carbonation of the concrete
[*]Pitting corrosion of the reinforcement caused by introduced chlorides
[*]Concrete corrosion as a result of:
[LIST]
[*]Sulfate attack
[*]Alkali-silica reaction
[*]Lime leaching
[*]Freeze-thaw cycles

Surface protection systems, such as coatings or impregnating the concrete surfaces with a hydrophobic agent, serve to improve durability and can be applied either immediately after production or as a measure to extend service life during concrete repair.
Concrete repair also includes all measures by which damages (cracks, spalling, etc.) are remedied and the original protective properties of the concrete are restored or improved as much as possible.

As already said, it depends on the processing and maintenance. And what you see in Rome are indeed precursors of today's modern concrete, but concrete as you know it today has only existed since Monier.

Again from Wikipedia:
Another major development leap was the invention of reinforced concrete by Joseph Monier (patent: 1867). That is why reinforcement steel or concrete steel is still occasionally referred to as Monier iron today.

The problem with all these materials, including your brick, lies in the way they are manufactured. Resources that do not grow back are consumed for bricks, cement, sand (not unlimitedly available), and steel. Enormous amounts of energy must be expended for their production (except sand, of course). Therefore, my conclusion is: we cannot do without steel and cement, but we have to use this material in these quantities. As much as necessary, as little as possible. Now surely someone will come and attack me, saying we are deforesting our forests. Yes, forests are being cut down worldwide to burn wood, to use chemically, to produce paper, and to make room for plants from which completely pointless ECO-fuel is produced. We have and will have enough wood, also in the future, to easily build our houses with it.

A little digression into wood philosophy, had to be done.

This is about insulated, airtight and windproof envelopes, the orientation of the house, window areas, cold and thermal bridges, etc.

Hello Friedrich,

You do realize that some of the oldest buildings in the world (meaning those that humans actually live in) are made of 100% pure wood.

Sorry, but when I read that, I always think of the prefabricated house industry, which advertises with exactly that slogan. What they forget to mention is that today's prefabricated houses have nothing, absolutely nothing, in common with the houses used as a slogan.

To stick with your favorite reference work (beware – the entries are, if at all, only rudimentarily checked for accuracy), one of the oldest still preserved churches is the Hagia Sophia; nowadays a mosque.

Rhenish regards

:rolleyes I already know that, it was just about the fact that it is wrong to generally classify wood as a building material as less durable than stone or concrete. Simply not being inhabited is enough to let even a wet-built house rot in a very short time. Yes, and the durability of a building today depends much more on current trends and technological development than on the building material. To make it clear, I am certainly a strong advocate of timber construction, but not a fan of prefabricated construction. Why? Because many findings of modern timber construction are only very reluctantly implemented there. Prefabricated house builders are good when it comes to the style of the houses, but the basic construction often looks pretty poor. Let me say, diffusion-open construction, installation level, insulation materials, etc. Yes, and as for Wiki, what I copied in fits, right??? Regards Friedrich

Resources that do not regenerate are consumed for bricks, cement, sand (not available indefinitely), and steel.

Regarding bricks and sand, I disagree. Bricks are mainly made from clay that is depleted with sand. Clay is a weathering product of rock. Even while you were writing this sentence, somewhere a weathering process involving clay or sand must have occurred again. Sand is nothing more than fine-grained weathered sedimentary rock.

If you grant your wood the ability to regenerate, then please also grant this to clay and sand, even though they do not form green little trees.

As always, first of all thanks for the answers and also the explanations about renewable raw materials

For us, the question still arises whether the price for a civil engineer and architect costs just as much as someone who can do both...

And whether we have forgotten anything else?

Or rather, what the best type of insulation would be

Hello,

...
- I have read a lot on the internet about passive houses, and on one site it said that it is almost impossible to build a bungalow as a passive house.

Why and how? Complete nonsense! Any building can be designed as a PH!
Whether it is actually economically viable in each individual case depends on the specific boundary conditions of the construction project.
Built on the Zugspitze, the additional investment compared to the energy saving ordinance standard would certainly pay off. At a mild climate location, questions regarding overall economic viability are certainly appropriate!
A PH cannot simply be realized massively, single-shell, depending on how one defines massive, without additional insulation.
Here, lightweight construction or multi-shell wall construction is usually more sensible!

Best regards
