Hello everyone,
I’m somewhat heat-sensitive. Until now, I have always lived in apartments that would get extremely hot in summer, despite maximizing shading during the day and ventilating strongly with rapid air exchange at night. Those were the days of my childhood spent in a basement apartment, where even in the height of summer the bedroom stayed pleasantly cool.
To get to the point: I definitely don’t want to deal with that in my own home. So, air conditioning is an important topic for me. My question is: what is the best way to maintain comfortable temperatures even in the peak of summer?
I have read that heat pumps can also provide cooling through underfloor heating, although the effect seems to be relatively mild. It’s also said that mechanical ventilation with heat recovery can be combined with cooling, but here, too, there are obviously fairly strict limitations. Finally, there is the conventional split air conditioning system, which certainly cools well but also consumes a lot of electricity. However, combined with solar panels on the roof, electricity costs should remain manageable since there is usually a surplus of electricity in summer that’s hard to use otherwise.
What would you recommend considering both cost and comfort? Maybe some combination makes sense, for example cooling with a heat pump via underfloor heating and additional cooling through mechanical ventilation with heat recovery – perhaps a moderate amount of cooling from two systems is sufficient in combination. Who has experience and can share knowledge and opinions?
Best regards,
HB1

Then, perhaps only a system half as "large" would be necessary, and the money saved could be invested in an intelligent control system or remote control.

Especially since sunlight through the windows causes much higher indoor temperatures than those outside.Well, I don’t know who lets the air conditioning run nonstop with unshaded windows, but in my opinion, they should be held accountable. Otherwise, a temperature difference of 10°C (18°F) compared to outside within an hour should be sufficient...

Well, I don’t know who sets the air conditioning to blast through unshaded windows, but in my opinion, they deserve to be tarred and feathered. Otherwise, a temperature difference of 10°C (18°F) compared to outside over one hour should be sufficient...Then you’d have to start with me. I like to sit in a BRIGHT!, air-conditioned office.
