Currently there are three subsidy-eligible KfW Efficiency House standards for new buildings:
- the Efficiency House 55,
- the Efficiency House 40 and
- the Efficiency House 40 Plus.
The thermal insulation of the building envelope and the so-called primary energy requirement are used as criteria for evaluating the attainment of these efficiency house standards.
The following rule applies here: the lower the number in the Efficiency House standard’s name, the lower the primary energy requirements of the house.
Good to know: Primary energy takes account not only of the quantity of energy in an energy source that can be used for heating, but also the energy consumption necessary for the production, transport or conversion of this energy. Thus, the primary energy requirement is an important indicator for evaluating the carbon footprint of a building. However, depending on the chosen heating system, it does not necessarily imply low heating costs.
Our Hanse Haus prefabricated houses already meet high energy-saving standards – both thanks to their well-insulated building envelope, built according to the KfW 40 Plus Standard, and their efficient heating systems.
In order to receive KfW subsidies for new buildings, some further efficiency improvements will be necessary.
We will be happy to inform you about which heating systems will help your Hanse Haus home fulfil the KfW subsidy criteria.
A KfW Efficiency House 55 is a house that requires a maximum of 55% of the annual primary energy requirement permitted by the Energy Saving Ordinance (EnEV).
No underside insulation is required for the floor slab here.
When it comes to the heating system, there are many possibilities for fulfilling the necessary requirements. You can obtain detailed information from our consultants.
For a home that meets the KfW Efficiency House 55 Standard, you will receive a repayment bonus of 18,000 euros.
A KfW Efficiency House 40 is a house that requires a maximum of 40% of the annual primary energy requirement permitted by the Energy Saving Ordinance (EnEV).
Hanse Haus’s quality advantage: the Hanse Haus building envelope built according to the KfW 40 Plus Standard.
The KfW 40 Standard requires a basement or a floor slab by Hanse Haus as well as underside insulation for the floor slab, or the Hanse Haus Efficiency 40 insulation package.
For a house that fulfils the KfW Efficiency House 40 Standard, you will receive a repayment bonus of 24,000 euros.
A house which meets the requirements for a KfW Efficiency House 40, and fulfils the following criteria, is a KfW Efficiency House 40 Plus:
- Electricity generation through renewable energy sources such as photovoltaic systems
- Stationary batteries as an electricity store
- A ventilation system with heat recovery
- Digital user interface with the visualisation of electricity generation and consumption
For a home built according to the KfW Efficiency House 40 Plus Standard you will receive a repayment bonus of 30,000 euros.
The Variant 45-175 show home fulfils the criteria for the KfW 40 Plus Standard.
You can visit this advanced, energy-efficient house with pitched roof at the Prefabricated House Exhibition in Bad Vilbel near Frankfurt.
Fore more information on the Hanse Haus Variant 45-175 prefabricated home, its floor plan and planning options, see the page with the details on this house.
You will find our Variant 35-235 show home in the Prefabricated House World in Wuppertal. This Hanse Haus prefabricated home also fulfils the criteria for the KfW 40 Plus Standard.
Drop by and see how beautiful energy efficiency can be. You will find the address and opening hours on our map. Or make a personal appointment with one of our consultants, who will be happy to tell you more about energy-efficient houses.
For all subsidy levels (KfW 55, KfW 40 and KfW 40 Plus) you will receive for the construction of a new Hanse Haus prefabricated house a loan of 100,000 euros per residential unit with a particularly low interest rate.
Thus, for our homes with granny flat, you will receive two loans at once.
