We have not changed the floor plan. Some work on El. We only contracted trades where the warranty was important to us. So heating/plumbing/electrics/2 windows. It was difficult to find companies that had the time and interest.

The problem is probably all too familiar. Craftsmen are missing

We have just moved from a drafty old building from 1902 into a KfW 70 house with decentralized ventilation and no Styrofoam (36 cm Poroton masonry), and the quality of living is worlds better.
Surely there are good humidifiers that help against the dryness caused by controlled residential ventilation?
And by the way, it is the outstanding long-distance suitability that absolutely justifies SUVs gaining an increasing market share. The problem is less the consumption. I was just in a well-known ski area in Austria. Wonderful air when you leave the hotel in the morning. Unfortunately, this good air on local roads is repeatedly temporarily spoiled by diesel vehicles of a well-known German car brand. An American V8 gasoline engine — naturally aspirated — with a proper catalytic converter is much more "environmentally friendly" there.

Hmm, I don’t know any statistics, but I believe that the majority of kilometers driven with an SUV are also on short distances. And a 1.2L 4-cylinder is certainly more environmentally friendly than a 3L V8 engine. And with my Touran, driving long distances is also quite fine, every day, sometimes with two children in child seats (including a rear-facing one). Even at 100-120 km/h and not at full throttle in an A4, SUV or whatever. Unfortunately no electric car or gas-powered... You can rationalize everything. Driving a car is rarely reasonable, whether the insulation craze is reasonable... How you build your house, whether insulated with styrofoam or with wood fiber, whether with controlled residential ventilation or like Nordlys with regelair and decentralized exhaust, everyone should decide for themselves. Both are possible. There certainly isn’t just one truth. Regards

Hm, I just recently read a test report about a well-known mid-size sedan with such a short-stroke 4-cylinder engine. Result: consumption at spirited driving on the highway around 10 liters.
I already managed that years ago with a 2.5 V6 naturally aspirated petrol engine and significantly lower particulate emissions. The most important point optimized here is obviously the manufacturer’s profit. They now save 2 cylinders in production....

Combustion engines should be optimized so that only the natural products CO2 and water come out of the exhaust....(These two substances you also excrete daily for biological reasons, really!)

Technically certainly easier to achieve than a battery for electric cars with a real 500km range, 50kg weight and a charging time of max 5min....

Thematically, however, we are now far away from the plastic bag topic

Not quite. My point is not that the passive house is a plastic bag, but that it is an obvious legislative goal to mandate this type of house in new construction for CO2 avoidance reasons. Mandatory! I don’t care if tego, haydee, or whoever else likes it, they can build it for themselves. But to mandate it for everyone, while at the same time not banning the Touareg or BMW Six-Hundred-Pants, that’s outrageous. Our Golf with three cylinders and 110 HP reaches about 180, consumes between 5 and 7 liters, has room for 4, and CO2 around 110 g. That is perfectly sufficient.

Now then. I don’t want to mandate everyone to drive such a car. Whoever wants the Six-Hundred-Pants, go ahead. But I could live well with speed limits and a tax preference for smaller cars. I can also live well with passive houses. Just please nobody force me to live in one. It’s also about freedom and rejection of social-pedagogical legislation and nanny politics. Karsten
