That title isn’t quite fair because it isn’t exactly true. But given the hype around Earthships I felt it is a deserved.
This short post was prompted by a longer article where the author inquires into the performance of Earthships in Europe. He raises exactly the same questions I encountered in my research. He made an effort to reach out to known Earthship projects in Europe to inquire about their performance and this is what I read between the lines:
- There are very few Earthships in Europe.
- Most European Earthships do not have permanent residents (if at all, cats do not count).
- There is very little information on performance.
- From what little information there is, it seems there are severe performance issues.
- There is very little sense of joy from all this.
The author is less blunt then me. I’ve written before that I think the Earthship “formula” is wrong for a cold and moist European climate. I also feel that the knowledge around Earthships is incomplete because I did not come across any information on why they are designed they way they are,why they work where they do and why they do not work in the European climate.
I did however find the Passive Annual Heat Storage book where (1) I finally found explanations on how underground houses behave and (b) answers to all the questions presented in the linked article and then some.
