The Living Lab Energy Campus (LLEC)

The Living Lab reality consists of three identical detached houses and two office buildings. Each of the three experimental buildings, about 100 square meters in size, is equipped with a different controllable heating system. The first house has heat pumps to regulate the indoor temperature; this is why it is also called the heat pump house. The second house - the electricity house - has electric heating, heating cables and solar thermal components. The fuel cell house has a natural gas fuel cell for temperature regulation.
This configuration allows the analysis of energy data of differently equipped households under identical weather conditions. The direct comparison enables the optimisation of cooling and heating systems and the further development of adaptive, anticipatory and grid-serving building concepts.
These houses have an e-car charging station and a technology garage with stratified storage. The e-car charging station charges the electric cars when needed, which also allows them to store excess green power in the car battery. In this way, the electric cars also act as buffer storage for times when little renewable energy is available or a lot of energy is needed at once. Both heat and cold can be stored in the stratified storage system and released when needed.
In this way, an intelligent neighbourhood network can also be set up and support the public power grid.
The office buildings are also equipped with sensors and provide important research data on real energy consumption. The researchers can thus optimise energy storage and use it through adaptive and predictive control strategies.

Research at SEnSSiCC is conducted by the Research Platform Energy as part of the Institute for Automation and Applied Informatics.
