The pilot site of Darmstadt (Germany) includes 45 buildings in Darmstadt and in the nearby smaller towns of Dieburg, Weiterstadt and Bensheim. The buildings have a total surface of approx. 55,000 m² with 688 dwellings accommodating approximately 1,514 tenants.
The buildings were built between 1959 and 1986; the facilities for energy, heating and water were installed between 1974 and 2003. Thus, the quality of the meters, the need to heat and the energy efficiency differ among the buildings from medium to bad. All dwellings were equipped with smart heat cost allocators and modern thermostatic valves.
A high proportion of tenants in the pilot site dwellings receive social welfare benefits and have a migration background. They are varying in age (18 to 85) and have a medium/low educational background.
