The law targets inefficient old buildings primarily. This would include buildings that have higher average oil or gas consumption due to their poor thermalinsulation. It therefore addresses private homeowners, especially the target group of 50 plus, as well as private owners of apartment buildings.
In the case that such a building has no thermal insulation, or only very weak thermal insulation, the heating after renovation must use 10% less fossil energy or at least 10% of the required energy must be obtained from renewable sources. There are two ways to do that:
Modernising oil or gas heating and insulating buildings
If you want to keep using oil or gas as heating fuel for the time being, it will be essential to replace the old heat generator with a new, more efficient model. The consumption of fossil energies can be reduced by at least 10% through the additional installation of new windows as well as any thermal insulation of the facade and the roof.
Switching to renewable energies
The fossil heating system will either be supplemented or replaced with a new solution that would achieve a share of at least 10% of renewable energies. There are several standard solutions for this. The changes will hardly be affected, however, if a building is already insulated.
