ᐅ Maximum room temperature?

Hello,

we have been living in our new timber-framed house for several months now and have generally been satisfied with the indoor climate. However, with the recent hot weather, it has become almost unbearable. Our bedrooms are on the upper floor, with an attic above. The rooms have about 0.5m (1.6 feet) of sloped ceiling, in case that might be relevant.

This evening, I measured 28.6°C (83.5°F) in my young daughter’s bedroom, which has one exterior wall facing north and one facing east, with a window in the east wall and the roller shutters kept closed all the time.
Is this “normal,” or is there a reason for complaint?

That is obviously not a defect. It is relatively warm at 36°C (97°F), and we will have to endure it for a week. Most of the heat in the room comes through the windows.
And when we reach minus 20°C (-4°F) in winter, we will have to endure that as well.

As I already mentioned, this was about my 2-year-old daughter's room, and I just want her to sleep well. It was not about finances... whoever wants to believe that, fine by me.

Here in this solidly built old house with brick walls, it took a while for the building to warm up, but the last three nights were only bearable without a blanket. So the temperature was definitely not below 28°C (82°F). Without active cooling in the summer or heating in the winter, every house adapts to its environment. For some houses, it just takes a bit longer. Insulation does help retain the temperature for a while, but a week of such temperatures... 28.6°C (83°F) already seems quite comfortable to me.

In my parents’ 30-year-old sand-lime brick terraced house, which doesn’t have roller shutters but does have internal shading, it stays very pleasantly cool (that’s where we fled to). They are also very careful to only open the door briefly and to ventilate only at night (unlike our apartment, the air isn’t even stuffy). Additionally, the warm air naturally rises into the attic... at least it’s dark up there because the windows are quite limited – but there’s always something 😀

I think everything has already been said:
1. Calling it a defect is a very strange idea
2. Use shading
3. Ventilate at night
4. Convince children to play either indoors OR outdoors
5. Use thermal mass next time – it doesn’t help if it’s hot for two weeks and points 1 to 4 aren’t followed, but it does support through significant thermal inertia and phase shift
6. Stop complaining (otherwise everyone always complains that there is no summer) and ultimately do your part against climate change 😉 (The airflow on a cyclist can be very pleasant)

I belong to the rare type of person who needs summer the least and doesn't complain when it's rainy and cold... so I allow myself to complain when it gets too hot 😉 Opening the windows in the morning and then keeping everything closed consistently is a good start. A fan by the bed or in the living room also helps. And now I'm just looking forward to the thunderstorm 🙂

Hello, I hope my quick question is not a disturbance.

How does it work if you run an air conditioner together with a controlled residential ventilation system with heat recovery?
Is there a negative effect where the air-to-water heat pump ends up working against it?
