REVIPOWER – Model training for energy-and resource-efficient neighbourhood renewals in Polish cities was designed by a Polish–German working group of multi-sectoral experts supported by additional expertise from external specialists. The innovative training materials consist of five independent training modules introducing energy efficiency and resource efficiency as a cross-cutting theme throughout the holistic approach to city renewal. Each module builds on the global and local challenges linked to climate change mitigation and adaptation, as well as taking into account the socio-economic priorities of Polish municipalities.
