What is a low-energy house or energy-saving house, what is a passive house or zero-energy house, and what is an energy-efficient house?
The topic of energy efficiency is gaining significance in a big way and the classifications, standards and awards in this area are diverse.
To help you navigate the jungle of energy-saving concepts more easily, we have collated the most important information on energy-saving houses and prefabricated housebuilding for you.
The energy-saving house as the standard for new buildings in Germany
house
Houses that consume significantly less energy for heating and hot water than the average energy standard are referred to as low-energy houses or energy-saving houses.
In the meantime, the energy-saving house has become the standard for new buildings in Germany.
Save energy at the highest level with a passive house
A passive house is a building which requires almost no classical building heating system, thanks to its efficient thermal insulation and the use of solar energy and passive energy sources such as waste heat from household appliances.
At Hanse Haus, we’ll show you one of our show homes built according to the passive house standard in our Show Home Park. Variant 45-192, a single-family house with pitched roof, impresses by the fact that it almost completely satisfies its heating energy needs with sunlight.
Come to our Show Home Park in Oberleichtersbach in Northern Bavaria and convince yourself with this energy-efficient Hanse Haus passive house.
Are you concerned about the environment and would like to build an environmentally friendly and sustainable house? Perhaps you would also like to be as independent as possible from public electricity suppliers and benefit from attractive subsidies for new buildings?
For our Hanse Haus prefabricated houses, we have created the following energy-optimised house concepts for you:
Building a KfW Efficiency House pays off
Through the Kreditanstalt für Wiederaufbau (KfW), the German government helps finance energy-saving houses that meet certain criteria with favourable loans and repayment subsidies.
Currently, there are three different subsidy-eligible KfW Efficiency House standards for new buildings: the Efficiency House 55, the Efficiency House 40 and the Efficiency House 40 Plus.
We’ll show you the heating systems with which your Hanse Haus prefabricated house will meet KfW’s criteria for subsidy eligibility, so that you can save money.
Plus-Energy House - your prefabricated house as an energy generator
The Plus-Energy House takes you one step further: you generate more electricity than you need yourself.
A photovoltaic system converts sunlight into electricity, which, when not being used, is sent to a storage device by an intelligent home control system. Surplus electricity is then fed into the public electricity grid.
