Build before or after 01.04.2016?

On page 3 under point 4. Instead of central ventilation, a decentralized one with heat recovery can also be installed.

Yes, it is also helpful that this is allowed. However, it has nothing to do with geothermal energy.

Yes, you need an energy consultant who calculates the entire construction in advance and also later provides the proof to the KfW bank. Many construction companies work with energy consultants, just ask the companies about it. They then offer the corresponding services.

In case it was not clear to everyone yet. This energy consultant can also be subsidized from 01.04. for new construction. 50% of the costs up to €4,000 are funded. Especially with regard to the thermal bridge proof, I think this is quite helpful.

Yes, that indeed, but under "Brine-water heat pump with surface heating system" I would have understood a system with surface collectors. However, it might also mean that surfaces (living room, bedroom, etc.) are heated.

That refers to underfloor heating

"Note: Product change as of 01.04.2016

[*]Please note: The subsidy application must be submitted before the start of the project. The subsidy is then paid out after the completion of the project.
[*]The subsidy can now also be applied for new construction projects for which an application is submitted in the product Energy-efficient Construction (153) from 01.04.2016.
The information sheets valid from 04/2016 will be made available to you from the end of February."

Do I understand correctly that the costs for an energy consultant are paid by the KfW at half up to a maximum of €4,000?

We are building a house with a prefab house provider who carries out the verification himself and probably hires or employs an energy consultant for this purpose. If the costs for this were shown, could I then apply for the subsidy?
