Zero
Earthship Zero is loosely based on the "Encounter" Earthship designed by Michael Reynolds of Earthship Biotecture.
The Earthship East Augusta project is the first iteration of this design in Australia. Also known as "Earth 1", Clive Digney is the proud owner. Clive invested in a weather station and indoor sensors so we now know how this building performs... and it is amazing! See the graphs below of the indoor, outdoor and greenhouse temperature. This building must be 'BEYOND TEN STARS'. The name "Zero"' comes from Clive's heating and cooling bill - which is zero!

Renderings and floor plan below of the Zero with 2 bedrooms (as you add more bedrooms and bathrooms the building simply gets longer in the east west direction).

Thermal Performance
It is quite rare for someone's home to be studied in such detail. Here is SCIENTIFIC DATA that demonstrates the extreme energy efficiency of this Earthship home in East Augusta, Western Australia.
The indoor and outdoor temperature is measured and recorded every 5 minutes. The temperature in the greenhouse (sunroom) is also recorded.
The graphs below show a hot summer week and a cold winter week. You can see how stable the indoor temperature is - it stays between approx 20C and 24C without the need for heating or cooling devices such as air conditioners. It simply uses an extreme form of passive solar design called... Earthship!
