The pilot site in Linz consists of six buildings and 361 dwellings. Since the dwellings are very modern and well insulated, the potential waste has been mostly avoided already. Hence, the service focus on optimal management and behaviour change with an overall target of 5%.

The pilot sites integrates an edss and ems for tenants. The system does not only provide information to the end customer by using a web based information platform, but it allows the delivery of measured data, not only images, to the customers almost without any delay. Measurement data is provided to the customer by using IP-based communication. This allows tenants not only to check the consumption values in real time, but also to be able to configure some switching and control equipment to react (switch), if a specific tariff is available or if a threshold has been defined, and / or if a certain power consumption is exceeded.



For more details visit the eeMeasure tool and the esesh deliverable D7.2 also covering qualitative surveys.



The tenant can access a forecast for consumption until the end of the year. In case of very high energy consumption a warning is shown on the portal.The tenant received saving tips in accordance with his consumption Monthly reports summarising the energy consumption of the tenant are generated automatically. Other features: The adaptor plugs can be used to switch on/off devices.



The business case for Linz allows for a multi-stage implementation with energy efficiency services on a first stage and integration of further services (e.g. smart home and entertainment), on a second stage prepared for opt-in scenarios. The utility Linz AG is modernising its services with the esesh solution also optimising internal processes. Customers are offered ‘more than energy supply’ alone by extending the range of services. On the first stage both, tenant and housing provider benefit immediately. The second stage cannot be sufficiently modelled as the benefits are specific to this pilot site.
