Hello dear forum,
We have been struggling for a long time with the question of which type of construction is most suitable for our building project. Maybe the experts and homeowners here have some good advice for us. Please note in advance: only verifiable facts for discussion, no old sayings, thank you!
Now to our planned project:
- Energy-efficient house with photovoltaic system including buffer storage
- All electrical work and interior finishing to be done by ourselves (except plumbing)
- Basement to be avoided (rocky soil, cost savings)
- Heating system: air source heat pump with water storage tank
- Living space of 140-180 square meters (1500-1937 square feet) single-family home
- Snow load zone 2
- Modern architectural style, open layout with large window fronts
- Budget approximately 300,000-400,000 Euros
Is brick construction still worthwhile for a modern house, or is it better to save time and a lot of money by planning a prefab house?
Thank you very much for your support

In terms of thermal transmittance, the "prefabricated house" has outperformed the "solid house" for forty years now (even with half the wall thickness!). However, based on your budget expectations, it doesn’t seem likely that you want to be an energy pioneer when building your home. The additional costs are quite comparable to organic certification standards.Aren’t most "prefabricated houses" automatically insulated well enough to easily achieve KfW 40+ standards through centralized mechanical ventilation with heat recovery and photovoltaic systems plus battery storage? That means about 25,000 euros (approximately 27,500 USD) extra for the technology, which is subsidized by 15,000 euros (approximately 16,500 USD) and reduces heating costs to zero?!

Tomtomsen2 Jun 2019 14:26I have seen it similarly so far. Maintenance costs for the equipment have been neglected.
But I want to be a bit more precise, so I will consult an energy advisor.

Aren’t most “prefabricated houses” already well insulated enough to easily meet KfW 40+ standards just by using centralized controlled ventilation systems and photovoltaics with battery storage? Probably not, otherwise many home builders wouldn’t offer different wall constructions for KfW 40—others may manage with supplementary measures alone. This is likely because the goal remains mostly theoretical.

So, that means an additional $25,000 for technology that is subsidized with $15,000 and reduces heating costs to zero?! That’s exactly what the €30,000 subsidy is for: to encourage investments that would otherwise reasonably be thought to make little sense. There’s always a Judas price for betrayal—in this case, the betrayal of one’s own gut feeling that it might be nonsense (or at least not convincingly cost-effective).
