Passive house as a logical consequence? Are there counterarguments?

Passive house = meets the criteria for passive house certification.
Or is that too simple now?

@ nahti

If you now also consult Aunt Google with "Passive house + certified passive house components," you will surely be able to explain to me why a 2% surcharge is more realistic than 40% ...

So we are building the PH without a heat pump for now, thus already cutting some costs with which Bauexperte reaches the 40%, and we also save the 10-15 thousand euros for the heating system. The floor slab will also be cheaper than in other passive houses because we are not insulating it but working with a crawl space and a warm floor ceiling (16 thousand euros and a U-value of 0.11). In addition, we will create 2 residential units in the house, which means we will even get 100,000€ for 0.75% plus another 10,000€ repayment subsidy. By the way, these KFW loans can be repaid early at any time without cost. I would really be interested to know how one could still come up with 40% more there. I’m happy to be convinced.

@ Vogtländer

Maybe for better understanding - you have decided on an EnergiePlushaus. That is a fine thing and - provided all the conditions are met, including price - apparently the right alternative for you.

However, you are not building a true PH, in which no heating system is allowed to be installed (and I have taken this into account in the surcharge), but there are significant additional cost drivers which together lead to a 40% higher price.

just inform yourself:

...What many do not know: With KfW loans, special repayments are not possible in all cases. Especially with the popular homeownership program (No. 124), the government promotional bank refuses extra payments. Only early repayment of the loan in a lump sum is allowed, but in this case, the KfW charges a prepayment penalty. "The homeownership program is a pure KfW product and is not subsidized by the federal government, therefore the special repayment option is omitted," explains Sybille Bauernfeind from the KfW press office as the drawback. Incidentally, the same disadvantage applies to program 159 (age-appropriate remodeling, elimination of flood damage).

: Program 124 can also be redeemed/paid off free of charge after the fixed interest period of 10 years. So nothing like being stuck with it for 30/35 years.

You always have the chance to get rid of it after 10/20/30 years. With other programs, even during the first 10 years, sometimes partially or entirely without costs.
