The necessary air comes in through the Regelairdinger and goes out through the Helios exhaust fan. But real fresh air is something else, it’s that feeling of the breeze. So once or twice a day we still open everything up, terrace, front door, and really create a draft. But you guys don’t understand what it’s about anyway. Young people also have no problem letting themselves be driven autonomously, while for me the automatic is already too much. Living self-determined... it is this disgust barrier that the Sinus Institute for Social Research describes between eco-moralists and the adaptives, which I feel between myself and the passive house.
