Germany got a new national standard in 2016 requiring them for special places like laboratories, childcare, retirement homes, museums, public buildings with irreplaceable goods (like a historic library), wooden homes (which are the minority here), wood working businesses etc.
The standard is applicable for new planning. There is no obligation to update existing buildings.

Of course we had discussions about the new standard only being implemented because the manufacturers want to sell afdds... I haven't had any experience yet and don't know about any nuisance tripping.
