And? Are you sweating? We are not! :P

Yesterday and the day before, it was a maximum of 25 degrees on the ground floor and first floor. The day before yesterday with active [Kontrollierte-Wohnraumlüftung] and yesterday for testing without [Kontrollierte-Wohnraumlüftung]. It is currently only 25 degrees as well.

Currently 24 degrees in the living room, but with the roller shutter down, I find it so depressing that I cleaned the car for 3 hours in the blazing heat yesterday.

Last night it was 21.6° in the ground floor in the house without cooling, this morning 21°, on the upper floor 23° perfect temperature.

It will probably be a bit warmer in the next few days since at night it no longer falls below the room temperature. The ventilation has not switched on for 3 days, I ventilate in the early morning hours and that's it.

26° C in the living room with shading. In the rest of the house as well.

For everyone still considering whether to install some form of cooling, I would say YES!
Today it's reaching almost 40°C outside. Phew! Luckily, back then we ticked the box for "Cooling yes or no?".

It runs very energy-efficiently via our geothermal floor heating (the cold is practically only pumped up). We have a comfortable 22.1°C in the rooms.

Honestly, this climate change really pisses me off. If anyone has a plot of land at the North Cape cheap to sell, please get in touch.

We have air conditioning, and it was by far one of the best decisions in the house. But 22 degrees with almost 40 outside? That would be way too cold for us. We currently have a constant 24 degrees in the house (only the bathrooms are warmer because they are not air-conditioned) and 22 degrees in the bedroom. Electricity consumption with these extreme outside temperatures is about 10 kWh per day. Otherwise usually 2-3.

PS: We have little shading because we don't want to sit in the dark

21.6 degrees at how much outside? >35? Sorry.. but I can't believe that. How is that supposed to work? Don’t you live in the house? Doors open sometimes etc. What about cooking etc.? Maybe try using a calibrated thermometer?

With shading and discipline, our neighbors have 25..26 degrees.
