Passive house as a logical consequence? Are there counterarguments?

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).

At 2% interest, you would have an additional €222 payment over 30 years of repayment.
At 1% interest, it would still be about €194. (But who actually gets 1% guaranteed for 30 years on €60,000.)
I don’t pay that much for general electricity and electricity for our heat pump combined. (Kfw 70). So you’d have to sell quite a bit of electricity for it to ever pay off.

What do you actually do with all the stove heat in a passive house? Open the window and let it out?

Hello,

the offer comes from the Czech provider you questioned some time ago?

So we get the Energy Plus house for €210,000 (€1,750/m²) fixed price (Energy Saving Ordinance reference house offer would be €160,000, so about 30% less) ... €23,000 costs the photovoltaic + battery ... so €27,000 extra cost from Energy Saving Ordinance to Passive

A solidly built prefabricated house for €1,333.00/m², a PH at a cost of €1,525.00/m² and an Energy Plus house at a cost of €1,750.00 - where is the catch?

Rhine greetings

When the sun is shining, I heat my buffer tank and charge the battery.
When the sun is not shining, I use the warm water from the buffer tank; when that is depleted, I use an instantaneous water heater. I only get electricity from the battery first; when it is empty, I buy electricity, and at the end of the year, during the annual balance, the purchase and feed-in are reconciled

I had already written this elsewhere.
We have 5.5 kWp on the roof—almost exactly south-facing.
In December last year, due to the very few sunny days, we fed about 30 kWh into the grid. There were also several consecutive days without sun. Our self-consumption rate that month was good (35%—when little is produced, a lot flows into self-consumption first). How far will you get if you store these 30 kWh in the battery?
That this is not an isolated case can be seen from January—we fed in a slim 90 kWh. The self-consumption was 30%.
November 2014 was about 120 kWh feed-in (self-consumption not yet measured at that time).

This month I am almost happy. In the past few days, we have already fed in more than 150 kWh. Here I would agree with you—with these 150 kWh via battery plus the self-consumption that has already occurred (not yet measured), one should almost be able to manage a fairly autonomous normal livelihood with an energy-saving lifestyle.

PS: As you can already see from the lines, we have no battery storage. We also do not use other measures for electricity efficiency (e.g., smart technology). Washing machine, dryer, and dishwasher are programmable.

Quite simple: in the (contemporary) quality of the equipment and fixtures.
Because even cheap builders can build Passive Houses.
If it really is an RD house, then a look into the construction performance description is enough to see where savings have been made.
That is why apples and pears are unknowingly compared here. But okay: to each their own. One the showcase technology, the other the wellness bathroom. However, I do not want to change the topic of the discussion here either.

It seems to me, however, that Vogtländer was with a "good" seller.
I just hope that the specifications for this project are also correct (orientation, vegetation, neighboring buildings... I did a little surfing), so that the yield will also be ample.

I am, however, surprised that one can simply take a standard house as a basis for such a Passive House or Multi-Energy House, I thought that more parameters belong to it, such as window size and location, that is, an individually planned house on accordingly large terrain.

Or do I not need to apply the requirements for a Passive House to a Multi-Energy House?

The price per square meter we got for a PH was just under €2,040. Additional costs not excluded. I can’t imagine that you can manage with €1,500 unless the provider saves on materials or good craftsmen. Our [Energieeinsparverordnung] house is only slightly below that.
