Hello everyone,
We have now been living in our house for six months (KfW 55 standard, although the heating demand is closer to KfW 40) and are really impressed with the indoor climate and comfort provided by the underfloor heating (operated by an air-to-water heat pump). The underfloor heating works flawlessly for us and seems well adjusted, at least the energy consumption is reasonable and the indoor temperatures are almost always comfortable. We don’t have a central or decentralized ventilation system; we ventilate traditionally by opening windows. So far, so good.
The only "problem" is the bedroom (about 17sqm (183 sq ft)): it faces northwest and is not directly heated (the flow temperature is set to zero), because even with the door closed it already gets “too warm.” The temperature in the house is around 21–22°C (70–72°F), which is our preferred indoor temperature. However, in the bedroom, we would like only 16–17°C (61–63°F), since 20°C (68°F) makes the bedding unnecessary 😀 But we simply cannot achieve this… Usually, we ventilate by opening windows crosswise for about an hour before going to bed, which lowers the temperature to around 13–14°C (55–57°F) — actually already too cold — but it quickly rises again and reaches nearly 20°C (68°F) in the morning. This causes waking up at night sweating and almost not needing the blanket. Not very restful… 🤨
Sleeping with the windows open is unfortunately not an option since we need complete darkness and absolute quiet.
How do you handle this? Is it something you just have to accept in extremely well-insulated houses, or how do you get the bedroom cooler? I can’t imagine all new-build homeowners comfortably sleeping at 20°C (68°F), as this doesn’t match the general recommendation for the [oB]optimal sleep temperature[/oB] for adults, which is between 15°C and 18°C (59–64°F).
Thanks in advance!

Almost no one can avoid having an air conditioning system (if they want to sleep well). Yes, that’s exactly how we’ve done it as well, and the investment is worth every cent 🙂

You mean spots inside the room, but he means spots outside above the window on the facade. You can see this on some (many) houses with ETICS.
(Try searching for "facade black above window") This is probably due to the window being permanently tilted open or the absence of a proper mechanical ventilation system, right?
