ᐅ How do you properly balance the requirements of the Building Energy Act against the standards of KfW 55, 40, and 40 Plus?

Hi everyone,
We are currently planning our single-family home and are receiving different recommendations from various builders regarding construction with or without meeting certain KfW standards. We are planning a solid masonry construction.
We would like to independently review the advantages and disadvantages and are wondering which points should be considered. From our perspective, these are the following:
Thank you for your feedback.

We would like to independently review the advantages and disadvantages and are wondering which points should be considered. From our perspective, these are the following:
- Financial considerations - The repayment subsidy for KfW55 is usually about the same as the additional construction costs, so it balances out more or less
- Indoor climate - Excessive insulation can negatively impact indoor air quality (we only know this from friends, but aren’t sure if this is always the case)
- Land utilization - Using an external thermal insulation composite system (ETICS) can achieve KfW55 with thinner walls, which on our narrow plot would allow about 10m² (108 sq ft) more living space
- Value retention - Are there any experience reports regarding the value retention of the different construction methods?
- Energy-efficient construction saves heating costs over time, so building energy-efficient should be cheaper in the long run
- KfW loans currently don’t play a major role, as banks offer similar or even better conditions
Thank you for your feedback.

It wasn’t difficult for us; we just built without any subsidies, and the house turned out exactly as we wanted.Yes, that’s definitely the right approach. After all, you only build once 🙂 My comments weren’t really meant seriously either. Although having a granny flat or accessory dwelling unit is something to seriously consider. It increases the resale value and attracts more potential buyers who might not be able to afford a large single-family home on their own with rising property prices. But I suspect, as 11ant wrote, that the subsidy for the granny flat won’t be sufficient!?H

After all, you only build onceThis phrase is often used to steer decisions toward more expensive or supposedly better options. However, it is completely meaningless and not generally valid. It is not worth basing your decisions on it.For a new build, it is definitely advisable to design the house so that parts can be separated once the children move out.
Either one of the children can occupy the separate apartment, or it can be rented out externally. Those who can afford it in old age may choose to leave it vacant, but this is not environmentally friendly.
Accordingly, we placed our bedroom with an adjoining bathroom on the ground floor, three children’s rooms on the upper floor, plus a separate full bathroom and a centrally located family room of 46m² (495 sq ft) with connections for the kitchen.
The stairwell can be closed off towards the ground floor, which is beneficial for heating operation.
But we would have built this way even without the two KFW loans.

When building a new house, it is definitely advisable to design it so that areas can be separated after the children move out.We separated the children’s spaces right from the start (they were 17 and 19 at completion) – they each have their own apartments. Of course, there are other practical options – such as moving out if the house becomes too large, keeping space for a retirement hobby, accommodating exchange students, renting out via Airbnb... – everyone’s situation is different.
