Sternchen3127 Dec 2019 20:24Hello everyone,
we hope you can help us a bit. We have purchased a plot of land, the notarization appointment has already taken place, and now we are waiting for the payment deadline. Meanwhile, we are already in contact with several solid construction companies that we have shortlisted and have received two offers so far; the third meeting was today.
So far, it was clear to us that we would build a KfW 55 single-family house (about 125 m² (1350 sq ft) living space on the ground floor and first floor) with a full basement (30 m² (320 sq ft) basement possibly used as living space with underfloor heating), a photovoltaic system, heat pump, and underfloor heating with individual room control.
Today, for the first time, we were asked why we actually want to build to KfW 55 standards. An efficiency house 70 would be around €20,000 - 30,000 cheaper, plus approximately €15,000 for the photovoltaic system. According to this, it would take about 15–20 years for the additional costs of building to KfW 55 with a photovoltaic system to be recovered through energy savings. The subsidies, except for the €5,000 from KfW, are no longer as favorable as they used to be and may not be cost-effective.
We have already received two offers from construction companies where this question about not building to KfW 70 did not come up at all.
We are now a bit confused and would like to exchange some thoughts on this.
Many thanks in advance.

General contractors often add extra features just to label their house as KFW55. In practice, building to KFW55 standards barely costs more today compared to the Energy Saving Ordinance.
If you end up with a "KFW57," it doesn’t really matter anyway, since the subsidies are not worth it.

We have already received offers from 2 construction companies, and neither ever asked why not KfW70. The question cannot even arise because KfW70 has been superseded by the Energy Saving Ordinance 2016 and is therefore no longer subsidized. For this reason, I also find it difficult to understand what exactly an "Efficiency House 70" is supposed to be: from the term, I would expect it to mean a KfW70 house (at a time when the Energy Saving Ordinance 2014 was not yet mandatory).

Well, you can ask a lot of questions: why a basement, which is considered lower-quality living space, when living above ground is better?!
Why have a shower in the guest bathroom, or why not have a shower in the guest bathroom?
So, there doesn’t have to be anything fixed about that!

By the time the additional costs for meeting the KfW 55 standard with a photovoltaic system were recovered through energy savings, the house would already be about 15–20 years old. Look, even the skeptic mentioned a reason here. You invest money in the house and get an ROI of 12 years. After 25 years, you are clearly ahead. There are worse decisions.
Regarding subsidies: take advantage of them if they help you reach your goal. However, don't lose sight of the goal itself because of the subsidy.

When it comes to subsidies: take advantage of them if they are on the way to your goal. But don’t lose sight of the main objective for the subsidy. This once again reinforces the saying that the devil always shits on the biggest pile, because ultimately it means that subsidies are just a nice extra for those who don’t really need them – which, in my opinion, raises questions about the purpose of subsidies aimed at private individuals (even those below the social security threshold).
