Citizen-led renovation aims to turn property owners into key players in the energy transition, moving from mere consumers to active agents. This approach promotes improvements in energy efficiency and the installation of renewable energy in buildings, especially in multi-family housing.

The benefits are numerous: greater thermal comfort, better air quality, reduced energy costs and protection against extreme weather events. In addition, it increases property value and contributes to climate change mitigation. When renovations are carried out collectively, the results are even more significant: cost savings, greater overall efficiency and a healthier, longer-lasting building.

Energy communities play a key role, offering advice, joint negotiation and access to innovative financing such as collective loans or crowdfunding. Examples such as Izgrei in Bulgaria show how local cooperation drives projects for insulation, solar panel installation and comprehensive improvements.

To start a citizen project, it is recommended to organise an owners’ association, carry out energy audits, define intervention scenarios and secure financing. Experience shows that collaboration, long-term planning and expert support are essential to move towards more sustainable and resilient buildings.
