Consequences of the coalition agreement for home builders?

Has anyone of you already dealt with the coalition agreement presented today and the consequences for (us) home builders?

It should be pleasant for new homeowners that there will be a tax exemption for real estate transfer tax if you will live in the property yourself. The rent control is supposed to be extended. 400,000 new apartments are to be built, of which 100,000 are publicly funded.

As an operator of a gas condensing boiler, I would have been very interested whether Nord Stream 2 will be put into operation or not, but I have not read anything about that. Natural gas electricity is supposed to end by 2040, whatever "end" means. The end for natural gas heating systems is supposed to be in the mid-2030s.

One wants to enable bidirectional charging of eCars. I think that's good :)

Sounds surprisingly restrained overall in the new construction sector. Private new buildings are generally supposed to install a photovoltaic system. Whatever the rule will be?

I am also unclear about the 65% renewable energy quota for new buildings from 2025? Could this mean a mandatory heat pump combined with the electricity mix and photovoltaics together with the KFW-40 minimum standard?

At least not KFW40+, so the questionable electricity storage is omitted.

Overall, high demands on new construction, but in my view, unfortunately little mandatory in the existing building stock. Yet it is said so nicely that ownership entails obligations. Except for listed buildings, much more can be achieved in the existing stock than KFW 70 to KFW 40.

One wants to enable bidirectional charging of eCars. I think that's good :)

I had to google "bidirectional charging" first, but I also think it's good. Even better than enabling it, however, is promoting it. ;-)

The self-builder is (reasonably) not the focus of the coalition agreement. He will benefit in the long term from the digitization of planning and approval. I find some measures particularly good, although of course still rather vaguely formulated. Here is what I found remarkable.

Excerpt:
As of January 1, 2025,
2992 every newly installed heating system shall operate on the basis of 65 percent renewable energies;
2993 as of January 1, 2024, for significant expansions, conversions, and extensions of
2994 existing buildings, the standards in the Building Energy Act will be adjusted so that the parts to be replaced meet EH 70;
2995 in the Building Energy Act, the new building standards will be aligned with KfW-EH 40 as of January 1, 2025. In addition, equal measures aimed at reducing GHG emissions can be used under the innovation clause.

--> Energy standards will be further raised. I think that building a single-family house will become somewhat more expensive because of that.

3012 We will create the foundations to increasingly consider the use of gray energy and life cycle costs.
3013 For this purpose, among other things, we will introduce a digital building resource passport. This is how
3014 we want to establish a circular economy in the building sector as well. Furthermore, we will develop a
3015 national wood construction, lightweight construction, and raw material security strategy. We want to facilitate market entry and approvals for innovative materials,
3016 technologies, and start-ups.

--> The shift to a circular economy can sustainably stabilize raw material prices and minimize resource consumption. I find this very good. The self-builder in 2022 is not affected by this.

3031 We will promote serial renovation by continuing and expanding the funding program within
3032 the BEG. As part of the research program "Future Building," we will further develop serial and
3033 modular construction and renovation, e.g., according to the Dutch Energiesprong principle,
3034 as well as identify and remove building planning and construction regulations hurdles. We will improve, standardize, and digitalize the building energy certificate. We
3036 will examine the creation of a digital building energy cadastre.

--> The real energetic gain for the climate lies in the existing building stock. The Dutch model is excellent. The self-builder in 2022 will also not be interested in this yet.

I had to google "bidirectional charging" first, but I also think it's good. Even better than enabling it is promoting it. ;-)

You only have to promote desired behavior that is not yet economically worthwhile for the individual. Bidirectional charging and discharging of a vehicle at the house is a no-brainer – especially with a spot tariff. The two happily rated newcomer Rivian and Sono have already conceptually included this in their vehicles.
