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 tips for energy saving and is available in German and Turkish. The energy management service addresses the issue of energy losses. The transport from production to consumer (tenant) leads to higher energy consumption and costs for tenants. Hence, a better management can save energy and costs for tenants. The Energy Management Service monitors and controls the domestic hot water and heating system for early fault detection and supports general management including maintenance.

Total consumption of tenants on building & property level compared to supply. In case of high energy consumption, malfunctions alerts are sent to service staff.

Cost-Benefit

The business case for Frankfurt is sound and tenants benefit immediately. The measurement provider benefits within a brief period whilst the introduction of eSESH allows for an even faster amortisation of the strategic decision for ICT-based sub-metering. The housing provider needs to wait a few years for an economic pay-off but benefits in the long run from reduced maintenance costs, higher rents and longer rental periods due to the reduction of conflicts.
