Home Acts and Ordinances Heat Act

As of: January 2009


The new Heat Act

The new Renewable Energies Heat Act entered into force on 1 January 2009. It stipulates that owners of future buildings must cover part of their heat supply with renewable energies. This applies to residential and non-residential buildings for which a building application or construction notification was submitted after 1 January 2009.

The owner is free to choose which source of renewable energies is used. The important aspect is that a certain percentage of heat is generated this way. The percentage depends on the type of energy employed. If solar power is used, for example, it must cover at least 15 per cent of the heat demand. At least half of the heat must be generated by renewable energies if solid or liquid biomass, geothermal energy or ambient heat is used.

The Act was drawn up with the objective that every owner of a building should be able to find an individually tailored, cost-effective solution. In addition, the German government has further increased its comprehensive support programme, the market incentive programme for renewable energies, to supplement the Act. It assists building owners in getting a start on heat from renewable energies.
