Hello everyone,
During the planning phase of building a house, you inevitably come across forums about home construction and topics related to energy standards. I have already read several books and browsed various websites on the subject. I should mention that I am not a professional in this field. What I have noticed is that the entire topic of "economic / ecological home construction" is heavily influenced by commercial interests. The so-called "smart" consumer is often misled by marketing terms and a government-led campaign for "CO2-efficient building." Books or websites dealing with this subject often do not provide clear, comprehensive assessments.
In the "better" literature, insulation materials are compared in terms of insulation value and whether they are expensive or affordable. However, I still cannot determine what makes the most sense for my individual case. I simply do not want to spend excessive amounts of money, especially on things that do not add value, such as polystyrene insulation. If additional costs for a particular heating system are reasonable over a feasible period, then yes.
Our current goal is to build a simple single-family home with about 130 - 140 sqm (1400 - 1500 sq ft). The house should cost around €200,000 (without outdoor landscaping, floor coverings, land, or additional construction-related costs; our expectations are modest).
I am interested in knowing, based on the current state of technology, what is the most energy-efficient and cost-effective building option?
Energy-saving regulation / building standards according to KfW, yes or no, and if yes, which level?
Solid construction or prefabricated house?
Condensing boiler technology or heat pump?
Thank you very much for your answers!
Best regards

It's not the case; this is a perfectly normal offer for the area, although some local companies sometimes offer even lower prices.
But nobody here will believe that anyway.

Calm down, Brauner... I got frustrated and annoyed earlier today too, but then I remembered something Yvonne told me a few weeks ago. Basically, when you say here that it’s possible to do things more cheaply, the message to others is also, “You’re foolish to spend so much...” However, besides self-inflicted issues—I’m only talking about KNX, venetian blinds, and a double garage with a remote-controlled roller door—it’s also frustrating to hear that in places like the Uckermark or Ostholstein, people are building nice houses for half the price.

People, what do we actually know? He says he lives in SH. That could be Norderstedt or Wedel, which would be expensive, or Süderstapel, which would be quite cheap, and they’d practically give him the fully serviced land for 40€/m² (4 USD/ft²).
He says he wants to spend about 200,000€ (220,000 USD) for the house. Without additional costs, without land, without utility connections or landscaping, etc. So basically a turnkey house. Here in SH, everyone sells that with a foundation slab but without painting and wallpapering, without a fitted kitchen. He doesn’t say he can’t spend more. He only asks: Is it economically worthwhile—not idealistically or ecologically—to pay extra for KfW 55 or even 40 standards? And he wants to know if it’s better to build with solid construction or prefabricated building. And he says a simple house would be fine, they’re not spoiled.
I tried to give an answer to his questions, I think a factual one. But then he gets an outrage wave thrown at him, from “never ever” to “rent instead” to “pricing impossible” to “you have no choice anyway.” And our house is used as an example: “If you want that, you end up where he ended up.” (What we’ve built is totally normal in our housing estate, and everyone builds here roughly at that level.)
I want to make this clear: I’m not saying “Whoever blows 500,000€ (550,000 USD) in Wiesbaden is crazy.” Maybe that’s the standard there, and you can’t change it. Just please accept that it’s different elsewhere. And yes, I stick to my point: The KfW standards are incentives to insulate more, use newer or more expensive technology, linked to subsidies, but these subsidies are more than offset by the builders’ higher prices, and from an economic point of view, it doesn’t make sense to me. I’m open to counterexamples. I can also say: Ok, I was wrong. That doesn’t diminish me. KarstenSince we all know everything better here: In Wiesbaden/Mainz, you only get a new build condominium for 500,000€ (550,000 USD)...[emoji2]

winnetou787 Aug 2017 21:05I’m starting to not care anymore; in 4 weeks, the construction of my affordable house, which is unique, will begin, and I’m looking forward to it.
