For everyone still considering whether to install some form of cooling, I would say YES!
Today it’s almost 40°C (104°F) outside. Phew! Luckily, back then we opted for "cooling yes or no?" and chose yes.
Our cooling runs very energy-efficiently through our ground source heat pump in the floor (the cold is basically just pumped upwards). We have a comfortable 22.1°C (72°F) in the rooms.
Honestly, this climate change is really annoying me. If anyone has a plot of land to sell cheaply at the North Cape, please get in touch.

I’m not an expert on insulation and such, but shouldn’t houses be insulated or designed in a way that makes the indoor environment independent of outside temperatures?
We are buying a house that, according to an energy report from 10 years ago, was already classified as an unrenovated old building. We recently visited when it was about 35°C (95°F) outside, and the living areas facing north were a cool 20–22°C (68–72°F), without any complicated heating or cooling systems and without shutters. It was naturally warmer under the roof but still bearable, and the south-facing rooms didn’t exceed 25°C (77°F). Heating in winter is obvious, but in summer, you should be able to retreat inside the house without relying on expensive systems.
As I said, I’m not familiar with this, but I just don’t understand why some people sweat in their new builds and need costly systems and shading like shutters when I can relax in my house, classified as an unrenovated old building, in “cool comfort.”

Without shading, it doesn’t work for us. I suspect that the indoor temperature would then be almost as warm as outside.
The insulation keeps both cold and heat out. Over the course of the day, a house gets warmer due to cooking (if you even need that in this weather), electronics, body heat, etc. At night, it cools down again. This is achieved through ventilation, either mechanical and/or automatic.
With new builds, you have the problem that once they heat up, the heat is stored in the walls and so on, and it’s not easy to get rid of it again. Ventilation doesn’t help much in this case.
Some people don’t set their ventilation system to bypass mode, so the heat recovery continues to run.

It’s not just about the age of the building. Thick walls also provide protection, as does a shady location and small windows. Many old buildings actually perform quite well in terms of temperature, although they usually have only small windows. With large windows, the situation can quickly change.
Currently, we have 24°C (75°F) on the ground floor and 25°C (77°F) on the upper floor. Honestly, I find it quite comfortable and wouldn’t want it any cooler (I do love warmth, and in winter we usually have around 23°C (73°F) in the house).
During the day, we always open the shutters on the sides of the house where the sun is shining. On the ground floor in the living areas, we have external venetian blinds, and I love them. They keep the sun out while still allowing plenty of daylight into the room. When I see neighbors sitting with their shutters closed all day in the living area, I am always grateful that we chose venetian blinds.
Still, cooling is definitely something nice, and I don’t want to deny that. In our old apartment (top floor), we often had 28°C (82°F) or more day and night in the rooms, and I really found that unbearable.

Steffen8025 Jul 2019 15:07Some people here really exaggerate! At night, when temperatures are above 20°C (68°F) or even much higher—like the upcoming night in Cologne with a low of 26°C (79°F)—the interior doesn’t cool down at all. Even a passive house heats up, unless they’ve started installing very small windows recently? And neither external blinds nor roller shutters keep 100% of the heat out. The fact is: a detached house in current!!! temperatures (over several days) cannot be kept below 25 to 26°C (77 to 79°F) without air conditioning. If it stays above 35°C (95°F) for a week and over 25°C (77°F) at night, you’re looking at 28°C (82°F) inside as well! I’d bet on it.
