ᐅ Lime plaster and lime paint, or something else – new construction

Hello,
In the new condominium, there is still relatively free choice regarding plaster and wall paint.
On the internet, you often read that lime plaster and lime paint are the more ecological options. However, since the developer wants a price equivalent to that of a new car according to the offer, I’m naturally wondering if it makes sense.
The problem is: this is a new build. Energy Saving Regulation 2014 with heat recovery system. Unfortunately, we have a slight history of mold-related issues... including needing to change wallpapers. Our current apartment is a renovated building from the 1960s. Despite ventilating multiple times, there is a cold spot on an external wall where moisture always accumulates, as well as at the window edge.
Since in the new apartment we will also be cooking, showering, washing, and drying clothes inside, we are naturally concerned that too much moisture in the air will lead to mold growth with standard plaster as well...
So, what to do? Use regular plaster and simply apply lime paint on top? Or rely on the heat recovery system to transport all the moisture away?
The bathroom will be tiled up to the ceiling. The ceiling will be covered with either wallpaper with a raised pattern or painter’s fleece with lime paint.
Please help. Thank you.

I could imagine it in the main bathroom, but for the rest of the house, I think it’s unnecessary.
Yes, we do all these things in the house. You really don’t need to worry about overly humid air with a mechanical ventilation system!

Yes, mainly to reduce electricity costs, but when I calculate it and see how little it consumes, that would be great.
We have 100 sqm (1,076 sq ft) of living space, just the two of us, but we are only being offered the p190.
What formula or power requirement did you use to select the p310?

fach1werk28 Mar 2018 21:30We have used both casein paints and lime paint. The lime paint has easily withstood all moisture exposure without damage, while the casein paint developed some small mold spots within 13 months between the sink and a few centimeters (inches) above the kitchen windowsill. Specifically, this area was covered with a tough, elephant-hide-like coating, but there was still organic material underneath. I had to remove it.
Best regards, Gabriele

We decided to use full lime plaster throughout the entire house, applied in two layers. The price difference compared to lime-cement base plaster was 2 EUR per m² (approximately 0.2 USD per sq ft) net, and it was absolutely worth it for us.
We would not want gypsum plaster.
The top lime plaster layer remains "untreated," meaning that once the plaster is dry, it is finished and will not be painted over. The color and surface look much more natural than the smooth, heavily painted white gypsum surfaces, which we would not have liked.

Because of heat recovery, controlled mechanical ventilation saves energy instead of using more. Without heat recovery, you have ventilation losses because you have to open the windows. Heat recovery recovers the heat.
Example: The ventilation extracts air at around 18°C (64°F) from inside the house and uses it to warm up the 5°C (41°F) cold air from outside. The air leaving the house is then only about 10°C (50°F), and the fresh air coming back in is about 17°C (63°F). So you get fresh air at 17°C (63°F) indoors. With manual ventilation, you would have exchanged 18°C (64°F) warm air for 5°C (41°F) cold air and then had to heat it up at your own expense.
But don’t get me wrong: due to the initial cost of the controlled mechanical ventilation system, it probably won’t be cost-effective. However, it definitely provides a significant increase in comfort.

We also have texture throughout the entire ground floor.
