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

You need to comply with the Energy Saving Ordinance. KfW 70 standard is sufficient for this. That was the term used in the past. It is no longer specially subsidized and is now considered the basic standard. Nothing more is necessary or cost-effective.
How can this be achieved most affordably? By building a house with 36.5cm (14 inches) Ytong blocks, plastered, without additional insulation, equipped with triple-glazed windows, underfloor heating, a gas condensing boiler, and 5 m² (54 ft²) of solar panels on the roof for hot water production. Optionally, a controlled mechanical ventilation system like RegelAir integrated into the windows and a Maico exhaust fan in the bathroom can be added. With this setup, you can manage with a basic house costing around 200,000. And it works. Karsten

Your post is unfortunately so filled with ideological assumptions that a serious discussion probably isn’t desired. I am currently interested in a serious and independent discussion. That’s why I am here in the forum, to learn from others’ experiences. It’s simply about not throwing money away unnecessarily to businesses. Don’t get me wrong, it’s not about building as cheaply as possible, but about building efficiently.
With 200,000 for the entire house, it is and will remain cheap, either like @Nordlys with 36 cm (14 inches) Ytong, but otherwise with Poroton and polystyrene insulation. Gas with solar is the most affordable heating method.
With your budget, you have very little room for maneuver.
