Frankfurt

The pilot site Frankfurt consists of two sub sites in Stadtallendorf and Eschwege.

In eSESH, 242 flats in 19 buildings are equipped with the service. In Stadtallendorf approximately 90% of tenants have a migrant background from Turkey. Most of them are employed or are former workers of the nearby chocolate factories. The majority of them came to Germany more than 30 years ago and stayed here after retiring. The level of education is relatively low.

The energy awareness service for tenants consists of a web portal to check and control their heating and warm water consumption. It contains hints and tips for energy saving and is available in German and Turkish for better understanding for non-German speaking tenants.

The energy management service addresses the issue that energy losses by transport from place of production to consumer (tenant) lead to higher energy consumption and costs for tenants. Accordingly, a better management can save energy and relative costs for tenants. The Energy Management Service monitors and controls the domestic hot water and heating system for early fault detection and maintenance management.
