I can confirm the excessive dryness problem. My gf moves to a passivhaus a few years ago, and I had real trouble with cry eyes during the night. After a year, I sort of adjusted, but it definitely doesnt feel very healthy.

You just need to cook more pasta: large pots of boiling water. :) More seriously: a very airtight house, which is generally desirable, does need a properly balance HVAC system. In some climate zones this means perhaps having a humidifier and in other zones a dehumidifier. Most people only think about furnaces and air conditioners when considering HVAC, but those mostly deal with temperature. Humidity has to be considered separately, often by different equipment.
- mlang23 7y agoI am guessing in many cases, there is no money left for humidifiers. You start out with the idea that you want to build a passivhaus. But you still have a limit on how much you can spend. So all the ventilation stuff is being installed, and the humidity control is being skipped. Which leads to each and every individual apartment considering their own humidifier, which probably pretty much kills the energy-efficientcy-idea that started the whole thing. At least that is what I observed in my limited small world. Humidity below 30% is cruelty.
