Why do "SMART" houses, have to be so complicated?

Unlike the fancy solar houses of the seventies,
. . . a Passivhaus design is pretty:
. . . . . . simple,
. . . . . . dependable, and
. . . . . . durable.
Exactly how durable, has just been demonstrated by
. . . Dr. Wolfgang Feist, Rainer Pfluger & Wolfgang Hasper in their study
. . . Durability of building fabric components, and ventilation systems in passive houses.

They examined the first Passivhaus dwelling, Dr. Feist's own,
. . . built in 1990 in Darmstadt, Germany.
. . . The house was a test bed, and has been monitored ever since.

The house is a very straightforward design,
. . . a simple box with masonry walls, wrapped with
. . . 11 inches of exterior foam insulation, and
. . . a mineral plaster stucco exterior, known as EIFS.
. . . The wall has held up rather well, and
. . . the roof, which has also lasted 25 years.
