if the topic is so important, I would rethink summer heat protection (especially the roof and wall construction) even more. Also, possibly build a passive house instead of KfW55.
My bedroom (facing north and WITHOUT any heating and thus without a PC) still remains tolerable in summer. 2-5° less could not hurt during longer heat periods.
All those who claim that only an air conditioning system can achieve what you are looking for are probably right, but from experience I can say that the 2-3° passive cooling from our brine-to-water heat pump in our passive house provides me with significant "relief" in summer. It has now already been hot enough outside for several days to judge that.
If I were to build again, I would still add a central air conditioning system AND an earth-air heat exchanger to the future house. Simply because I never knew that air conditioning systems consume so little electricity, which you anyway have left over in summer with suitable photovoltaics.
Thank you for this contribution.
I have not yet dealt with the implications of a "passive house" at all. I will put that on my list.
Again here: Central air conditioning and earth-air heat exchanger together sound very tempting. I just have to find a way to make the topics more tangible for myself.
