Lawyer wanted to sue the construction company

Has an expert ever looked at the whole thing? In hot summers it gets very warm especially in new houses, controlled residential ventilation has nothing to do with it.

What use is a great 40+ house to me if I then need an air conditioning system, can someone explain that to me?

Well, almost right, heat that comes in stays inside. So with a new building, just make sure that no heat comes in.

Hm, and how do I do that in summer with the large window surfaces that are so trendy? Sit behind the blinds all day? This whole efficiency thing is kind of a curse, I want my old house made of pumice stone back, it was always cool.

Unfortunately yes! But your old house certainly had a few trees in front of the windows, the surroundings were green. And the window areas were probably only half as large, no forced ventilation.

: Your questions are excellent and justified. We insulate houses like crazy and then in summer we can no longer sit outside in the fresh air without later having to cool down the inside again. Such constructions are simply built past the practical needs of people who like to live both outdoors and indoors.
All the KFW standards are a good vehicle for capturing subsidies and for statistical surveys with comparability on the subject of energy-efficient building.
Some good solutions simply exclude you from the KfW standards. Then you just ignore the subsidies and build in a way that you can live in it very well and still be CO2 neutral in operation.

I ask for examples
