Cold despite 20 degrees air temperature

Hello,

I have now been living in my new building for 1 month. (3 gable house) It was still built according to the Energy Saving Ordinance 2013. I have underfloor heating but no ventilation system. As a requirement to meet the Energy Saving Ordinance, my insulation value had to be 15% better than the guideline value at that time. The thickness of the exterior wall insulation is according to the latest standard and even exceeds the 15 percent. Airtightness is also given. The attic was insulated accordingly as well. Drying of the new building was carried out using construction dryers. The relative humidity after one month of living, even with the bedroom and bathroom occupied, is mostly 50-60%. Now to my problem. Although I have, for example, 20 degrees in the bedroom, it feels much colder to me. Right now, at 5:30 am, I have 55% humidity and 20 degrees room temperature here. Still, I have a "clammy" feeling. The top blanket also seems clammy to me. Under my duvet, I am practically sweating, but the surroundings seem much colder. It can’t actually be radiant cold from the window (one window triple glazed) or from the walls (with the described top insulation). Everyone I ask says it will improve over time. The building is very fresh and there is probably still a lot of bound water in the building that needs to come out first. Then there is always the saying about moving in only in the third year and before that in the first year tenants should be enemies and in the second year friends for the purpose of drying out while living in. Can the cold sensation be caused by only 55% humidity according to the hygrometer? Or what else could it be? Thank you very much

Heating and ventilating, I can't say more about that...

Thank you very much for the response. Since you are a moderator, I assume you know about the subject? Your answer sounds a bit like "how many times do I have to say it"... is that really the crux of the matter? Then what I have been told is true? Thank you

Hi,

since 1 month my new building

the place is brand new and probably quite damp. That is still normal. In the first year, only a lot of ventilation and sometimes heating generously helps.

Saving energy only starts in the second year...

Many greetings,

Andreas

That's how it is... no matter how much insulation etc. you stick to the house... you can't outsmart physics... the moisture stays inside, especially if you "only" keep the mentioned rooms at 20°...

))))....is the "only" 20° meant sarcastically (I actually only need about 17-18° in the bedroom) or should heating initially be done at higher temperatures?.. (cold air absorbs more moisture, right??). At the moment I can hardly manage to keep the temperature below 20°. The heat seems to be rising from below into the bedroom. The double door from the living/dining/kitchen area (open living) to the hallway, and thus to the first floor, is still missing...
