If you are planning to build or buy a house or a new owner-occupied flat, you are entitled to subsidies from the state in the form of a low-interest loan from KfW, which also comes with a repayment subsidy.
An important prerequisite for this is that your property meets the standard of a KfW Efficiency House or a comparable passive house. The higher the energy standard, the higher the repayment subsidy. This means that you have to repay less.

The KfW Efficiency House
It is worthwhile for you to pay attention to the KfW Efficiency House standard when building or buying a property. This allows you to save energy costs, increase the value of your property, improve living comfort and also benefit from subsidies.
There are different levels for the KfW Efficiency House, indicated by key figures. The smaller the indicator, the lower the energy requirement and the higher the subsidy.
For new buildings, the KfW Efficiency House 40 Plus, 40 and 55 standards are subsidised. The decisive factor for classification is the energy quality of the property. It is measured with the reference values primary energy demand and transmission heat loss.
In any case, it makes sense to involve an energy consultant in the project, as energy-efficient construction requires complex expertise. A qualified expert ensures that all measures lead to the desired result. For the funding of your new building project, you must involve an energy efficiency expert.
