Brenet workshop «Building-related Multienergy-Systems: Exploring future products and services for decarbonization»

The brenet building network held the third workshop in the series "Building-related Multienergy-Systems" on 24 March. The focus of the event was on solutions with multi-energy systems (systems with different energy sources for heating, ventilation, cooling and power supply) for single and multi-family houses.

In the workshop, which was conducted in English, small innovation groups discussed one of the following questions and develop solutions:

  • Planning multi-energy systems in single-family homes: How can planners be supported in combining PV, battery, electric mobility, thermal storage and heat pump?
  • Hydrogen for mobility and as seasonal storage: Which solutions enable decentralised use in buildings?
  • Battery storage in the building or in the bidirectional vehicle: How can the management of the storage be optimised in the area of conflict between profitability – energy supply – climate?
  • Data and data management: What new solutions are required for the holistic multi-energy system?
  • Interfaces in multi-energy systems: What new definitions are needed for sustainable systems?
  • How can real estate managers be motivated to replace fossil heating systems with more environmentally friendly (multi-energy) systems?
