Alright, I can still agree with the ventilation system, but the rest is quite special. Probably 80 percent of people won't install the other two things. I don't really find that representative for our calculation.
But a ventilation system alone can add >70€/sqm depending on the design.
By shading system I mean blinds or similar. They don't have to be automatically and centrally controlled via home system xyz, but the more windows there are, the more it makes sense.

As said, electric shutters with timers from Busch Jäger are included for me.
