ᐅ Passive House as a Logical Choice? Are There Any Counterarguments?

Hello everyone,

we are a family planning to build a house. So we have tried to gather as much information as possible. In the process, we have come across the passive house concept.

Do you know that feeling when you think you understand something and then wonder why everyone isn’t doing it that way? That’s exactly how we feel about the passive house right now. Are we missing something, or are there any arguments against building a passive house? I really can’t think of any.

Of course, it is somewhat more expensive, but if I recover the costs soon and then save money for life, I don’t understand, for example, why I would build a KfW 70 house instead...

So please either correct me or agree with me, but my conviction about the passive house feels a bit unsettling.

Thanks for your thoughts.

Additionally, for a standard house complying with the Energy Saving Ordinance, the program 153 is not available, @ypg , so the savings are indeed realized compared to that.

No, but for KfW 70, as I mentioned! And there, the manageable investments still pay off... while from KfW 70 onwards it no longer makes economic sense.

But whatever... in a few months the information probably won't be up to date anyway

As always, when it comes to energy topics, people say "it’s not worth it" from all sides. How do more expensive tiles pay off? How does a fireplace pay off? How does building a single-family house pay off at all?

At 2%, everything pays off

Hehe, you can make any numbers look good... The fact is: You have to invest more money upfront, which means you also have to pay back more in the long run.

And with KfW loans, you usually cannot make special repayments, so you are stuck with them for 30 years.

And Bauexperte is right, 40% additional costs are realistic... 2%, no way.

A 40% cost increase is absurd. Or are you really all building for 1300€/m² (120 USD/sq ft)?

LOL I even built for 1400€ per square meter, and it was a KfW-70 house... I wouldn’t really go any lower than that... unless you plan to end up with major structural repairs later on...

If you really have very cheap offers—whether for passive houses or regular ones—take a close look at what you are actually getting... don’t assume that cheap means good quality.

Good morning,

Why?

Or do you think I just made up that number because I enjoy teasing you and the users here? Maybe you should describe what you understand by a passive house, then we might get closer to the point.
