Energetic

The building sector is considered to have great potential for realising the development of sustainable and resilient energy supply systems. The reason for this is that the decentralised integration of renewable energy systems and the simultaneous use of their own storage potential can relieve the pressure on supply grids.

In addition, the combination with combined heat, power and cooling systems and load-shift technologies enables a significant improvement in the security of supply. However, well-founded and targeted further development requires a cross-system consideration of all the individual technologies involved, taking into account the control and hydraulic interfaces. Due to a lack of suitable test buildings, isolated individual technology tests are currently primarily carried out under laboratory conditions or simulation calculations. This does not allow for a cross-system analysis that takes real user behaviour into account. For this reason, the ‘Energetikum’ was designed as an interdisciplinary living lab. It enables the further development of alternative energy supply systems, storage technologies, control strategies and digital building management methods on a 1:1 scale, taking real user behaviour into account. The building was constructed with a high degree of flexibility in terms of energy supply and the measurement, control and regulation technology that can be used. The extensive hydraulic system technology also creates the necessary flexibility for the cross-system development of new component storage concepts and the prerequisites for the validation and further development of building and system simulation models. The Energetikum has been used as an office building for the employees of Forschung Burgenland GmbH since April 2015. In addition, numerous research projects - in which the ENERGETIKUM is used as a demonstration and test object - have already been acquired. These multi-year research projects are carried out in co-operation with corporate partners and are also funded by the FFG. This emphasises the sustainability of the chosen research approach and the established research infrastructure.

The further expansion of renewable energy systems requires intelligent networking between energy supply, storage and distribution. This requires new and cost-efficient solutions. Inevitably, the building of the future will therefore also have to take on the tasks of short and long-term storage of wind and PV power. The establishment of a single technology solution (e.g. large-scale electrochemical storage systems) cannot be expected in the short or medium term for ecological and economic reasons. However, solutions based on coordinated and comprehensively optimised overall systems that make the building usable as an energy storage system represent a promising alternative. However, this requires precise knowledge of the dynamic behaviour of thermally active components, geothermal heat exchangers and heat pump systems, solar hybrid collectors, fuel cells for power-to-gas-to-power applications, etc. In addition, there is a lack of communication models between the buildings and the energy supply that are reduced to the essentials (e.g. simple load shedding systems via one-way communication with the grid operator through targeted utilisation of the thermally active storage masses) as well as intelligent (model-based) predictive control strategies. In order to solve these problems, the ENERGETIKUM was equipped with advanced measurement, control and regulation technology (MSR), a test environment for stationary fuel cells and outdoor geothermal heat exchanger units.
