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

So, what exactly are we referring to?

Are you actually paid by this American car manufacturer with laptop batteries, who doesn’t have to make a profit, for doing such persistent marketing for them? After all, there are users here who can and want to spend quite a bit of money. But the topic is house construction!Hmm... so the only "non-persistent" way would have been to not reply to the post? I find your hostile reaction exaggerated.
The core issue is that changing mobility also imposes different requirements on houses, and especially those building new should consider whether they want to address this today, plan to retrofit in 15 years, or believe the anticipation is wrong and therefore consider the topic irrelevant.
Which government or company provides mobility is irrelevant to these considerations.
Relevant to the original poster’s topic of construction cost-effectiveness, we had concluded regarding energy that initially a gas boiler, but after its lifespan—15 to 20 years later—photovoltaics, ideally combined with electric vehicles and heat pumps, would be the most economical lifestyle.
Therefore, it is economically most sensible to build the first option today but do so in a way that allows conversion later.

What exactly do we mean?House construction + additional construction costs + all work required to make the house move-in ready (painting, flooring).
No furniture, no kitchen, no costs for the land.
It was claimed that anything under €1700 per square meter (approximately $180 per square foot) is almost impossible.
If you exclude some of these items, the price per square meter decreases, but then people are not really talking about the same thing.

winnetou789 Aug 2017 16:59Sometimes, only the house itself is mentioned here.
When I calculate it, I also arrive at 1,700 euros.

When I calculate it, I also get around 1700 euros.So now we’re talking about the same thing. That means 1700 €/m² (approximately $158 per sq ft) in the Uckermark region for a move-in ready house including all additional costs, but excluding the land and its related expenses.
This is realistic and should give the original poster a good idea that, even when building economically and carefully, there isn’t much room to go lower than this price. After all, you’ve already saved on many extras. And you’re living in what, pardon the expression, is a low-wage area of Germany.
