Background information

The Integrated National Energy and Climate Plan (PNEC) targets, among other things, the decarbonisation and reduction of energy consumption in residential and tertiary buildings. As part of this, a new subsidy programme has been implemented:he so-called 'Klimabonus'. This programme aims to make homes more energy efficient, facilitate the choice of emission-free mobility solutions and, finally, manage the environment and forestry environments responsibly. This change will be accompanied by measures to support lower-income households in particular. The Klimabonus programme can be divided into five categories:

• Sustainable mobility (support maintained and extended in duration);
• Renewable energy (simplified and increased support);
• Protection of biodiversity (aid maintained as it is);
• Sustainable housing (simplified and reinforced support);
• Targeted aid for low-income household.

Content of measure

Regarding the sustainable housing, the Klimabonus programme replaces the ‘Prime House’ and ‘Clever Fueren’ programmes, with the aim of making more rational use of energy and developing renewable energy sources. This programme provides technical and financial support for :

• the energy renovation of an existing building (over 10 years old). This may involve work on just one part of the thermal envelope (roof, external wall);
• maximising the use of renewable energy, in particular the installation of technical systems that make the most of renewable energy sources (heat pumps, wood-fired boilers, etc.);
• the construction of sustainable buildings and housing;
• Developing sustainable eco-districts.

The plan to decarbonise heating systems in buildings includes a transitional phase, known as the ‘phase-out’. This action is voluntary, with the support of financial aid and collective solutions. If the voluntary approach proves to be too slow or insufficient, only replacement with heating installations using a minimum of 70% renewable energy will be authorised. The ‘phase-out’ does not entail any obligation to replace a (fossil) heating installation that is still in proper working order. It applies when replacing an existing boiler that is out of service or no longer authorised under current regulations. In addition to state support for sustainable housing and renewable energy, some local authorities also provide support for energy efficiency, as well as subsidies for work carried out by a private organisation: Enovos. In addition, the energy renovation of low-performance residential buildings is accompanied by an advice service. The plan provides for the creation of a national entity for energy renovation projects, decarbonisation and the installation of photovoltaic systems for residential buildings. The main aim is to provide comprehensive, structured support for owners of low-energy-performance residential buildings, in terms of identifying potential for improvement, planning, financing (taking into account all existing support mechanisms) and implementing energy renovation, decarbonisation and photovoltaic installation measures.

Use of measure

Older homes, new private buildings, as well as company and collective buildings are targeted by the measure.
