ᐅ Strong odor when turning down the underfloor heating system

Hello,
we have the following problem. In our newly built house (moved in 6/22), a sweet/sour slightly pungent odor, similar to “stale sweat,” has appeared over the past few weeks. I would not describe it as chemical or musty. We have now observed that it comes from the bedroom and only affects this room. We locate it along the floor near the exterior wall. We turned the heating fully on to see what would happen. The odor disappeared. When we turned the heating back down, the smell returned. Sometimes it feels like a real “cloud” of odor rises upwards toward the windowsill. It seems likely that the smell is coming from the heating system. Has anyone had a similar problem or any ideas? We would appreciate any advice! We have not yet installed baseboards. Ventilating makes it temporarily better. There are no laundry baskets or similar items in the room.
Floor: underfloor heating, screed, PE foil, cork parquet.
Thank you in advance!!

Hello, has the problem been resolved by now or is it known what caused it?Unfortunately not. However, it does not seem to originate from the floor, but rather from the walls. Another family of the developer is experiencing the same issue. We have temporarily moved out of the bedroom. The indoor air quality analysis was successful, and now the manufacturers of the individual building materials are being consulted.J

Interesting topic. I can’t quite tell— is that something like silicone or adhesive in the joint, or is it just an optical illusion?
No, that is the “edge insulation strip” from the screed layer. The gray area is just the wall; we didn’t paint all the way down to the floor. The indoor air quality analysis showed the following.

Hello,
we have the following problem. In our new build (moved in 6/22), a sweet/sour slightly sharp odor, similar to “stale sweat,” has been present for several weeks. I wouldn’t describe it as chemical or musty. We have now noticed that it originates from the bedroom and only affects that room. We would localize it along the floor / towards the exterior wall. We turned the heating fully on and waited to see what would happen. The smell disappeared. When we turned the heating back down, the smell returned. Sometimes it even feels like a “cloud” comes towards you. It almost rises up towards the windowsill. So it seems likely that the smell comes from the heating. Does anyone have any ideas or has experienced something similar? We would appreciate any advice! We have not installed baseboards yet. Opening the windows temporarily improves the situation. There are no laundry baskets or similar items in the room.

The indoor air analysis showed the following (see photo). Does anyone have an idea? The smell comes from the exterior wall.

What does the expert (who conducted the analysis) say? I’m also just an amateur, but to me it sounds like there was something in the paint and/or plaster that either shouldn’t have been there or has reacted with something else, causing the current off-gassing.
At least for hexanal, I found that it is often present in coatings. So, it could be that the emulsion paint didn’t cure properly, which is why something is off-gassing there. However, whether this is due to “expired” paint or possibly an incompatibility with a previously applied plaster, filler, or primer, I can’t say for sure...
