Do you know that feeling when you think you have understood something and wonder why not everyone does it that way?
That's exactly how we feel right now about the passive house. Have we missed something or what arguments are there against a passive house? I really can’t think of any.
Sure, it’s a bit more expensive, but if I get the costs back soon and then save for a lifetime, I don’t understand why I should, for example, build a KFW 70 house...
So in our case, that means I do have additional investments of about 30% (€60,000) but even have a slightly lower monthly burden thanks to the lower interest rate and the savings on ancillary costs.
So please convince me otherwise or agree with me, but my conviction for the passive house feels a bit uncanny to me.
Well, I don’t want to convince or cure anyone like you of something else now, but one counter-argument could be:
I take from the €60,000 additional investment for 30 years (purely fictional since we don’t know how prices will hold up) €1000/year for gas. Over 30! years that amounts to €30,000.
I don’t have to finance the €60,000, so I don’t pay interest either. I think electricity will break even... yes, I am very skeptical about that since quite a bit has to be bought additionally in winter.
Additional to the €60,000 could be: extra soundproofing for the freezer room (I once heard somewhere that due to the technology a higher noise level could arise), which I don’t have to finance now either...
So, disappoint me, but somehow from a gut feeling (I’m too lazy for elaborate calculations right now) I come to a better result if a) I don’t have to finance these €60,000, or b) invest part of it in a bit more square meters (messy, I can also heat these additional square meters with gas).
