Super Sustainable Buildings via Thermal Dynamics & Passive Solar.
An Earthship is a type of passive solar house that is made of both natural and upcycled materials (such as earth-packed tires). Earthships can be completely off-grid or partially off-grid.
Earthships can be built in any part of the world, in any climate (with a permit) and still provide electricity, potable water, contained sewage treatment and sustainable food production.
Earthships are thermal mass homes first,
passive solar homes second.
Whatever temperature goes into an Earthship, it will hold… and since it is also a Passive Solar House, it is also very tight and interacts only with the sun and the earth for heating and cooling, providing stable comfort year round in any climate.
Thermal/Solar Heating & Cooling
Earthships maintain comfortable temperatures in any climate. The planet Earth is a thermally stabilizing mass that delivers temperature without wire or pipes. The sun is a nuclear power plant that also delivers without wires or pipes.
Comfort in Any Climate. Keep the building warm in the winter and cool in the summer. Comfortable with little to no utility bill / fossil fuel.
This increases both psychological and physiological comfort.
Solar & Wind Electricity
Earthships produce their own electricity with a prepackaged photovoltaic / wind power system. This energy is stored in batteries and supplied to your electrical outlets. Earthships can have multiple sources of power, all automated, including grid-intertie.
Security. Always Have Power. electricity: off-grid, grid-intertie. Solar, Wind, Biodiesel, Geo-Thermal, Micro Hydro.
Waste Water Treatment
Earthships contain use and reuse all household sewage in indoor and outdoor treatment cells resulting in food production and landscaping with no pollution of aquifers. Toilets flush with greywater that does not smell.
Contain & Treat Waste Water. Treat and clean greywater. Flush toilets with treated greywater, clean and clear. Improves and adds to conventional systems without replacing. Liquid Waste Water Planters provide for prolific Food Production.
Natural & Recycled Materials
House as Assemblage of by-products: A sustainable home must make use of indigenous materials, those occurring naturally in the local area.
Think Global. Act Local. A sustainable home must make use of local (indigenous) materials, those occurring ‘naturally’ in the local area.
Earthships catch water from the sky (rain & snow melt) and use it four times. Water is heated from the sun, biodiesel and/or natural gas. Earthships can have city water as backup. Earthships do not pollute underground water aquifers.
Potable Water. Generally speaking, a sustainable building with the methods outlined uses about half as much fresh, potable, drinking water as a conventional building.
Earthship wetlands, the planters that hold hundreds of gallons of water from sinks and the shower are a great place for raising some of the fresh produce you’d like to have in the winter, but find expensive or bland tasting from the supermarket.
Grow your own food. Earthships use interior greenhouses for treatment of grey water, as well as to grow food and enhance the natural beauty of the home.
