KfW 55 - Ventilation system yes/no? - Experiences

Blinds opened on the north side, south and west only slits open. It is dark but it is cool.

It would be interesting to see how that works with venetian blinds. We will have a mix of blinds and venetian blinds. Venetian blinds on the south side, the ground floor on the west side as well, otherwise mostly blinds.

Rollers or roller shutters?

I meant roller shutters, internal shading doesn't help much.

Raffstores protect against heat just like roller shutters, only it is not as dark.

I also meant shutters, I always say roller blind.
