WP2: Renewable Energy Systems from Building to District Scale


Renewable District Energy Systems (RDES) are developed from building to district scale, for existing buildings and quarters as well as for new projects. Concepts will focus on a systemic approach that considers factors such as retrofitting, phased development, long operational life times, future technologies and possible changes in building use, energy markets and climate conditions. Integration of fluctuating renewables requires also new RDES control algorithms. Consequently, we will develop models, design and operational tools, validated with test results and apply them in demonstration projects. Proof-of-concepts will reduce the implementation risks for the industry and accelerate dissemination. Based on phase I results, research topics for holistic RDES developments focus on Building Energy Systems solutions suitable for the Swiss building stock, e-mobility integration, new Multi Energy Grid / Energy Hub technology solutions integrating long term storage technologies, and control approaches considering Internet of Things (big data).


The research activities within this work package are structured into three modules:

  1. Renewable distributed energy systems development
  2. Energy systems control and management
  3. Application and demonstration of RDES technologies
