The pilot site Karlsruhe Rintheim is located in the federal state of Baden-Wurttemberg in Germany. In the years 2010 and 2011, 17 buildings have been connected to the district heating systems. These buildings are involved in eSESH.

The planned Energy Awareness Service is directed to the tenants with the purpose to raise consciousness concerning energy saving potentials in their private households. Using the energy portal, the tenants in Rintheim can check and control their energy consumption. This includes heating energy and hot and cold water consumption on a monthly basis as well as electricity consumption on an hourly basis. To offer a higher frequency for electricity consumption data, a link from the energy portal to the web portal from Stadtwerke Karlsruhe (SWK) is planned. Hence, if tenants want more detailed information about their electricity consumption, they can click to the portal from SWK over a direct link in their energy portal where data illustration is in a 15 minutes time resolution.

The planned Energy Management System is directed towards monitoring and controlling of the heat supply systems in Volkswohnung’s building stock. VoWo is in charge of the management of about 30 buildings in the residential quarter Karlsruhe-Rintheim. Since September 2009, sixteen of these buildings have been connected to a district heating network. At this site, flat-plate solar panels on the top of the building support the domestic hot water production in addition to the district heating supply.

The main aim of the EMS is to ensure early fault detection and the improvement of the performance of the heat supply system. A bad performance leads to higher consumption and to higher energy costs for tenants. By implementing a monitoring system, it is possible to identify those systems which have unsatisfactory energy performance and to take early actions to improve them.
