Economics
The comparison of life cycle costs showed that the subsidies offset the additional costs of 12% compared to a passive house.
Two- to four-room apartments are offered for rent in sizes ranging from 60 to 120 square metres. The average rent is 13.50 euros/m². This includes the energy supply, including electricity, as a flat-rate rent. This saves the housing company accounting costs.
Certification: Efficiency house plus
