What exactly is an energy-efficient house?
Can you recognize an energy-efficient house from the outside?
Where can I find good information on this, or who has experience with it?
Many questions about a topic I hear more and more often but never quite understand what exactly is meant by it.
Best regards,
Tina

Hello,
first, the term energy-efficient house needs to be defined. There are "energy-efficient houses" that go back to the Anno/Tuk standards.
A current standard for energy-efficient houses includes various levels, starting with efficiency house 70 or 55, up to KfW 60 and KfW 40 houses.
The number indicates the energy consumption of the house.
Then there are also passive houses.
For a layperson, it is probably difficult to recognize such a house from the outside. But basically, you can assume that all newly built houses meet at least the Energy Saving Ordinance 2007 standard or, from October, the Energy Saving Ordinance 2009.

The figure provided by KFW indicates the primary energy demand and has little to do with the actual energy consumption.
A passive house receives the same subsidies as any other KFW-certified house. The criteria are listed on the KFW website. Whether you save money with a KFW loan can also be demonstrated with a calculation example.
Only passive houses "can" operate without a heating system—electricity is still generally needed, especially since it is more cost-effective to feed solar-generated electricity into the grid completely and draw power as usual.
