Based on DIN, the expression of a normal flat is introduced for apartment houses in the FRG. Such a flat has
four rooms; it is occupied by 3.5 people; it has a bathtub, a hand basin, and a sink. Flats of other sizes,
number of occupants and different equipment are converted to normal flats using the relations given in the
standard (NL). The situation in our apartment houses, massively built until the recent past, is similar.
Flats intended for 3 to 4 people are equipped identically with normal German flats. Smaller flats tend to
have smaller bathtub or a shower; larger, so-called two-generation flats tend to have an extra hand basin.
Apartment buildings with luxury flats and high standard equipment, with higher number of fittings, or
fittings equipped with high standard drain armatures, both hot water and heat energy needs must be
adjusted.
