I have been living in my newly built house (a three-gable house) for one month now. It was built according to the 2013 Energy Saving Ordinance. I have underfloor heating but no ventilation system. To meet the requirements of the Energy Saving Ordinance, my insulation values had to be 15% better than the standard at that time. The thickness of the exterior wall insulation meets the latest standards and actually exceeds the 15% improvement. Airtightness is also ensured. The attic was insulated accordingly as well. Construction dryers were used during the building drying phase. After one month of living here, the relative humidity is usually between 50-60%, even when the bedroom and bathroom are occupied.
Now to my problem. Although, for example, the bedroom temperature is 20°C (68°F), it feels much colder to me. Right now, at 5:30 a.m., the humidity is 55% and the room temperature is 20°C (68°F). Still, I get a damp feeling. Even the duvet feels damp. Underneath my blanket, I am practically sweating, but the surrounding air feels much colder. It shouldn’t be radiation coldness from the window (there is one triple-glazed window) or from the walls (which have the described top-level insulation).
Everyone I ask says this feeling will go away over time. The building is very new, and there is probably still a lot of moisture bound in the structure that needs to dry out first. I also keep hearing about moving in only in the third year, and having friends or family live in the house in year one and two for drying purposes.
Could the cold sensation really be caused by only 55% humidity according to the hygrometer? Or what else could be causing this? Thank you very much.

MatzeGalle11 Mar 2017 07:23Thank you for your reply. Since you are a moderator, I assume you have some expertise in this matter? Your response sounds a bit like "how many times do I have to say it"... is that really the crux of the matter? Does that mean what I have been told is correct? Thank you.
Hello,
The house is brand new and likely quite damp. This is still normal. During the first year, the only solution is to ventilate a lot and heat generously at times.
Energy saving really starts in the second year...
Best regards,
Andreas

That's right... no matter how much insulation you add to the house... you can't outsmart the physics... the moisture stays inside, especially if you keep the mentioned rooms only at 20°C (68°F)...))))... is the "only" 20°C (68°F) meant sarcastically (I actually only need about 17-18°C (63-64°F) in the bedroom) or should the heating initially be set to higher temperatures? (Doesn't cold air hold more moisture?) I'm currently hardly able to keep the temperature below 20°C (68°F). The heat seems to be rising from below into the bedroom. The double-leaf door between the living/dining/kitchen area (open plan) and the hallway—and thus the first floor—is still missing...
