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?

Our friends have brick walls almost 50cm (20 inches) thick, and their home is wonderfully comfortable... without any air conditioning, no basement, and outside temperatures of 39°C (102°F).

The thicker the wall, the longer it can withstand high temperatures. A thick concrete roof would be ideal for this – but other alternative additional roof insulation methods can also help to some extent. I will look into a central air conditioning system. I have read that it costs around 4,000 euros, which I am happy to invest.

It’s getting warmer in Germany; prepare for it and buy an air conditioner if it gets too hot for you!

That was an honest question, purely out of curiosity, as I’m not really familiar with this topic. If you, for whatever reason, cannot understand that, that’s fine, but then please spare us the arrogant answer!

Thanks to everyone else for their constructive contributions.

“Comfortable” is very subjective. When it was 40°C (104°F) outside, I also found the 25°C (77°F) inside on the ground floor quite pleasant. I believe it’s not the walls alone that matter, but especially good shading of the windows (otherwise, a lot of heat enters) and roof insulation that keeps the heat out. Otherwise, even a brick house won’t be able to maintain indoor temperatures below the outdoor average after a week of heat.

Hello,

I also don’t understand the question about the defect.

But do you really expect deep-frozen products in a freezer containing only a few items (thermal mass) after several days without active cooling (plug unplugged)?

I consider that to be a belated excuse!

Oh – I do understand the question very well. It’s less the question itself that bothers me, and more the intention behind it. If you had asked something like “how is it with you in similarly built single-family houses” – “how do you deal with it?” – “what measures do you take?” I would have let it pass without comment.

Your budget is probably almost empty – quite normal after getting through the housebuilding adventure. I can also imagine there are still many smaller items to be completed and that you have to wait until you have saved a little more money. Also normal; you’re in good company.

What is not normal – and that’s why I replied – is your openly expressed search for someone to “blame,” because you – what? Didn’t give much importance to summer heat protection when planning your house? Decided to skip a heating system that can also cool? Perhaps also a mechanical ventilation system with heat recovery? Your budget no longer allows for the purchase of an air conditioning unit?

It is a widespread – and in my opinion – very unpleasant habit to presumptively assign “blame” to the house supplier, with the goal of transferring money into one’s own pocket. That’s exactly what you meant by the addition “Is that ‘normal,’ or a reason for complaint??”

As long as this kind of attitude is posted publicly here, I will respond; regardless of the sensitivity toward unwanted comments.
