Research Activities

  • Energiekonzept Wiener Neustadt Phase 1

    Advice and technical support of the project klimaaktiv missionzero Wr. Neustadt. Report on the missionzero-relevant data in Wr. Neustadt.


    Establishing a sustainable energy and economic system and dealing with the opportunities and risks of digitization are among the greatest challenges facing our society. BSAIO aims to put these two aspects in relation to each other. The methods from the fields of Big Data, Machine Learning and Artificial Intelligence, which are based on digitization, as well as increasingly powerful optimization algorithms, offer the possibility of operating systems in a more sustainable way and saving resources both in their planning and operation. To this end, all necessary knowledge is to be imparted and the methods are to be applied directly to practical tasks. At the same time, the targeted use of methods based on digitisation for responsible and sustainable use of resources should help to create best practice examples in this area.

  • Bio(FLEX)Net

    Due to the benefit of being storable, the production of biogas allows the equalisation of fluctuating energy production from renewable energy sources as wind energy or solar energy. The present project aims to develop adaption measures within a retrofit in order to change the plant operation with the target of offering flexible energy on demand.

  • RealLifeBiomass

    The active involvement of end users in further awareness raising is the key element of WP3. Interested house owners (n=100) are actively involved in measures and methods for the sustainable improvement of air quality and for optimizing the operation of their own heating system. A citizen science approach is chosen (end users collect data on their heating behavior themselves and then forward it to the project consortium), leading to increased end-user awareness.
