Existing Properties

Renovation of existing real estate to an efficiency house
What is an efficiency house?
We define an efficiency house as an energy standard for residential buildings. The values 40 to 100 define the different efficiency house levels. The lower the value, the lower the energy requirement of the property and the more subsidies you receive.
You can claim the higher funding for the renewable energy class if the heating system based on renewable energies covers at least 55 % of the building's energy requirements.
