KfW - construction: is it necessary or not?

Maybe it’s also due to age, but sometimes I have the feeling that nowadays way too many so-called standards are set when building among the builders themselves, as if you couldn’t build anymore without this or that nowadays. I read, among other things, that a house without underfloor heating is complete nonsense, that all kinds of xy values are mutually overachieved or that only one thing or another seems possible and is considered a fact. This also often applies to the topic of KfW. In the end, I want to feel really comfortable in my completely individually designed place and more value should be placed on this in detail; but often the money unfortunately runs out there. So far, I have not had all that regarding KfW, controlled ventilation, underfloor heating etc. pp. or only partially in my various living situations and have still always ensured that I feel great in the house. I like bold individuality in design, which no one else can feel for me. With or without KfW – that will not change your well-being in the house. If it is only insignificantly more expensive you can do it, otherwise I would invest the money elsewhere in directly noticeable living and quality of life.

And what would that be?

And what would that be?

As stated, the emphasis was on ME:
- Air conditioning, because the humidity makes life in summer difficult for me
- a great, individual floor plan in collaboration with someone who can interpret floor plans well according to my wishes
- a glass roof over the terrace
- a really stylish shower or one full bathroom per floor plus a guest WC
- a small, separate guest area
- a garden sauna
- blinds or Venetian blinds......
etc.....

These are things I have always found extremely comfortable and pleasant so far, which is why they will be included again in the new house. That only applies to me personally; these are my priorities on the list but I gladly invest more there; less in the garage, car, outdoor facilities, higher KfW standards (without making my garden ugly in the process).
In addition, I generally handle energy carefully.

That already sounds good. Of course, you can legitimately question his statements, but he might also be able to show you reference projects. My former house was built at the time with 36cm brick walls, and I enjoyed living there. Of course, the floor plan, location of the windows, etc. are also very important, as are many other points. Personally, I also like to rely on a person who gives me a down-to-earth impression and someone who recommends what he knows well. But with the floor plan, I would definitely want to find my very personal needs reflected.

And that’s the kind we’re looking for. Not someone who wants to push something on us, but someone who says what he can do and also helps us with decisions.

And we already have our own ideas and a rough draft. It is based on the location of the house. Where there is a lot of light, the rooms that are used often (living room, children’s rooms) should be located there, and of course a south-facing terrace.

We will keep looking.

How did you do it?

We built ecologically and waived the subsidy. With our own forest, which produces significantly more biomass than we need for heating, and the desire for radiant heat, a basic stove was the obvious choice. That means you are already out of the KfW system. Of course, you can still build highly efficiently, no one forbids that and it conserves resources.

As written, the emphasis was on ME: - Air conditioning, because humidity does not do well for me in summer - a great, individual floor plan in collaboration with someone who can resolve floor plans well according to my ideas - a glass roof over the terrace - a really stylish shower or one full bath per floor plus a guest WC - a small, private guest area - a garden sauna - blinds or Venetian blinds ...... etc..... These are things I have always found extremely comfortable and pleasant, which is why they will be included again in the new house. This only applies to me or these are my priorities on the list but I gladly invest more there; less in garage, car, outdoor facilities, higher KfW standards (without making my garden ugly in the process). In addition, I generally handle energy carefully.

Thank you, there are some nice things in there (-: I could check off every item, only the air conditioning I really think I am missing .... Maybe really retrofit it for the bedroom ...

Once again interesting to see the influence politics has on facts
and how it leads to completely nonsensical claims, such as gas being similar to an air-water heat pump.

Every air-water heat pump failed until the Energy Saving Ordinance 2014. Only when politics decided to simply increase the actual primary energy factor politically did air-water heat pumps become viable and lead to cheaper construction methods, since even relatively poor building envelopes became economical.
Every general contractor or prefab house manufacturer must have been happy. Because where did the additional profit go now,...
Photovoltaics usually cover about 25% in private households, and the energy is produced at the wrong time.
The actually delivered electricity cannot be CO² neutral, since the entire renewable energy produced in Germany currently only just covers the current digitalization.
And even experts like Prof. Lesch have no solutions for the future here.

At least politics trusts the citizen to do calculations and think logically.
That is why KfW40+ is only funded with battery storage. Which ecologically is a disaster similar to all electric cars. No one will buy a new battery for €21,000 in an ID3 after 8 years. The old one can currently only end up in an incineration plant, as it is not recyclable. Environmental damage and child labor in Africa or Latin America for lithium and cobalt mining are not even mentioned.

Whether KfW55 or not is currently not even a question, because a KfW55 house is simply cheaper to build than an Energy Saving Ordinance house. The lower operating costs are not even considered.

Then in 2021/22 comes the enormous loss in value of Energy Saving Ordinance houses, when according to the new Building Energy Act only passive houses are approved as new buildings.

One must never forget that many political decisions are often strongly influenced by lobbies. Which are not the lobby of the average consumer.

Because if the state suddenly misses the mineral oil tax, on which energy can this then only be levied?
