Living in a passive house is nothing extraordinary. The combination with elements of an earth house can be very comfortable as demonstrated by Passiv-Erdhaus GmbH in Günzburg (see Links).
“Erdferienhaus” is the fourth house of the small Passiv-Erdhaus housing estate in Günzburg. It is for rent from a private landlord.
Günzburg is located in Bavaria, South Germany, between Munich and Stuttgart in the Swabian Danube Valley.
