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

What gimmicks have I saved on, besides ventilation?Do you have KNX or similar? Shading system? Then, as mentioned, the ventilation. That’s what I mean. Many people build themselves because they want features like these. That naturally drives up the price.

With additional costs, it would be around 220,000 or so. That would put us well above 1,800 per square meter (approximately 167 per square foot).

Naturally, that drives up the price.Well, I can understand the ventilation system, but the rest is quite specific. Probably 80 percent of people don’t install the other two items. So, I don’t really find that representative for our calculation.

winnetou789 Aug 2017 17:53If by that you mean roller shutters, I have those electrically operated.
I just checked, and on top of the base price of 30,500, I have additional features compared to the standard building specification.
So the price would be for 1,400 m² (15,100 sq ft).
