We're lucky enough to have had the opportunity to help out with a great project happening at the moment. Gus and his partner Sarah along with a crew of awesome helpers are building a radically sustainable home for their young family in Hikuai on the Coromandel Peninsula. It's an Earthship house. Pictured are some of the team in their Cactus get-up.
A little bit about Earthships:
An Earthship is a passive solar house that is made of both natural and recycled materials. The main components being used are earth rammed car tyres, cans and bottles.
Earthships are designed to work as autonomous buildings using thermal mass construction and a natural cross-ventilation system that is assisted by thermal draught to regulate indoor temperature.
Earthships are built to utilize the available local resources, especially the energy from the sun.
Earthships are buried into the ground. All rooms are connected by a long corridor which is also used as a greenhouse. All greywater runs into a botanical cell along this corridor.
The whole north-facing side of the house is made up of 70-degree glazing admitting lighting and heating.
The thick dense earth-rammed tire walls provide thermal mass that naturally regulates the interior temperature during both cold and hot outside temperatures. Low e glazing would be perfect for this.
Above this glazing is a 37 degree flashing for PV solar panels to harness the suns energy for electricity.
We are looking forward to following the progress and will have updates here throughout. For more information check out their Facebook page here.
