1to3 energy is building regional renovation hubs across Germany, bringing together local energy consultants and craft businesses to renovate buildings efficiently and environmentally friendly. These hubs consolidate cross-sector expertise and create a scalable infrastructure to drive the energy transition in the building sector.

In line with the principles of the Circular Economy, the focus is on the sustainable use of existing buildings. By improving energy efficiency and integrating renewable energy sources, resource consumption is significantly reduced, and the need for fossil fuels is eliminated. 1to3 energy’s digital collaboration platform ensures seamless processes, rapid implementation, and a cost-optimized transformation of the building stock.
