What are Earthships? Sustainable Architecture - #UNLITTER

Written by Tessa Whitby - @UNLITTER Team

It’s no secret that conventional construction industry infrastructures contribute to a long list of negative environmental impacts including deforestation, the disruption of natural land and habitats, the use of fossil fuels, as well as further pollution. What if there was an alternative way to build affordable houses and communities that work with nature to meet basic human needs? Is there a way that those housing and building designs could incorporate recycled materials and also be fully sustainable? In the desert of Taos, New Mexico, Mike Reynolds has an answer. Earthships are radically sustainable buildings, using advanced biotecture tactics and designs that take the meaning of #UNLITTER to a new level.

Earthship designs first came about in the 1970s but have truly attained perfection in the last decade or so. What started as a simple dream to sustainably live #offgrid has been growing into a small revolution in recent years through the vision of Earthship founder Mike Reynolds and his many students and partners around the globe. The growing academy programs offer unique educational opportunities to anyone strong-willed enough to invest time and work into eco-construction systems that could entirely transform the way communities are built. For those who question that such a sustainable dream is even possible and want to witness it with their own eyes, many of these bio-structures are even available for eco-tourist, nightly rentals.

So, what is an Earthship?

Whereas houses are structures independently powered using fossil fuels, expensively maintained, and continuously renovated to withstand the effects of nature over time, an Earthship is more like a living, self-sufficient “vessel.” There are six main principles of sustainability that every Earthship design must incorporate:

  • Water Harvesting

  • Contained Sewage

  • Thermal Mass/ Thermal Cooling and Heating

  • Building with Recycled and Natural Materials

  • Solar and Wind Electricity

  • Food Production

With entire walls and foundations built from recycled tires, bottles, cans, and other recycled materials, Earthship eco-construction designs combine repurposed trash with natural materials to support a completely self-sufficient system. These vessels have the capacity to generate their own electricity, heat and even catch rainwater to be filtered and used for multiple jobs. By using a rain-catching roof system that captures, filters, and recycles water. It is possible to use the same water to shower, flush the toilet, and also feed plants before it’s no longer usable.

How do Earthships use Biotecture?

The term biotecture can be defined as architecture that uses living plants and other organic materials as a crucial part of the design of buildings. The food production aspect of Earthships can actually take up more space in a structure than living space. This allows for year-round produce supply for residents and is an integral part of the water filtration, cooling, and heating systems. Every system in the Earthship structure works together to reuse and circulate water and energy at a cost-efficient and environmentally safe level.

The end goal is to have a fully self-sufficient house that provides nutrient-rich produce and is entirely supported by sustainable systems that operate on renewable energy sources like wind and solar. Biotecture at this level of functionality could mean no fossil fuels, no utility bills, and a year-round supply of local organic fresh food even in harsh winters and poor conditions. Using tires, cans, glass bottles, and other recycled materials alongside natural materials allows us the opportunity to #UNLITTER our trash in a way that might even outlast conventional building materials.

How can Biotecture be better than conventional infrastructure methods?

Below, you will find a list of mission objectives found directly on the Earthship website. These goals set an example of exactly how biotecture methods and designs can offer more functionally sustainable benefits than the conventional infrastructure methods, which we now recognize as destructive to the environment. If a sustainable future is to become a reality, supporting sustainable designs that embrace a symbiotic relationship with the environment and renewable energy is essential to consider as we reshape conventional industries.

  • To reduce the economic and institutional barriers between humans and their habitat.

  • To reverse the overall negative effect that conventional human housing has on this planet.

  • To create a less stressful plane of existence for humans in an effort to reduce the stress that they in turn place on the planet and each other.

  • To interface economics and ecology in a way that immediately and tangibly affects current pressing problems with life on earth.
