Hello,
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.

It also depends a lot on whether ventilation is installed and how many windows the house has, and so onI also find that difficult to understand. We have a lot of glass and ventilation, yet there are still significant temperature differences between the rooms.

just wanted to give a quick update. Thanks to all the helpful tips here (ventilation and heating), I have now maintained a consistent relative humidity of max. 45%. I have kept the heating on well (sometimes up to 23°C (73°F) in the bedroom). I even didn’t ventilate for a day just to see what would happen. Even then, the humidity did not rise above 45%.
What really confuses me now is the following:
The bed linens in my bedroom feel damp, even though the humidity is 43% at 21°C (70°F). When I sleep, I start sweating after a short time. I mean, nobody needs to sleep at 21°C (70°F). 18°C (64°F) should be perfectly fine. But why do the bed linens seem (or actually feel) damp at these conditions?
