[Tool 3]: comprehensive renovation of 8.500 very diverse homes

.

The partner cities will demonstrate the technical and financial feasibility of in-depth renovations. The focus here is on a collective approach. The demonstration projects include collective renovations of houses into low-energy and nearly Zero Energy Building almost-energy-neutral homes, thorough renovations of large and small apartment blocks, communal solar panels, district renovations, shallow geothermal energy, energy investments for vulnerable groups of the population and third-party funding for energy renovations. Good practices will again be translated into guidelines, playbooks roadmaps and training courses that will be distributed among the stakeholders on a large scale.
