Foundational Concepts
The design of Earthships is revolutionary in sustainable architecture, incorporating rigorous principles and elements to minimize environmental impact and maximize energy efficiency.
Earthship Architecture Principles
An Earthship embodies the principle of sustainability by utilizing recycled and upcycled materials and local resources. Architect Michael Reynolds pioneered this concept, envisioning structures that are self-sustainable and eco-friendly.
They prioritize the use of recycled cans and bottles, as well as earth-packed tires, and other reclaimed materials to form the building blocks of the walls, which serve as thermal mass and structure. This design harnesses the principles of sustainable architecture by reducing waste and reusing materials that would otherwise contribute to pollution.
Sustainable Design Elements
The sustainable design elements of an Earthship are comprehensive. They include:
Recycled materials: Tires, cans, and bottles are integrated into the construction.
Renewable energy: Solar panels and wind systems provide a clean energy source.
Water harvesting: Rainwater is collected, filtered, and reused to reduce water waste.
Natural temperature control: The Earthship leverages thermal mass and cross-ventilation to regulate indoor temperatures without relying on external energy sources.
Passive Solar Heating and Cooling
Passive solar heating and cooling are central to the Earthship home design. Strategic placement of windows allows for the absorption of sunlight, which is stored in the Earthship’s thermal mass and released as heat when temperatures drop.
During summer, the design prevents excessive heat from entering the living spaces, maintaining a comfortable climate. Earthships are sited to maximize exposure to the sun, a fundamental feature of their passive solar architecture, which eliminates the need for mechanical heating and cooling systems.
Constructing Your Own Earthship
Utilizing non-standard building materials, these homes leverage the abundant resources that are often categorized as waste, alongside the gifts of the natural environment.
Recycled Materials
In the construction, recycled materials play a pivotal role. A primary component is old tires filled with compacted earth, which serve as the building blocks for walls.
These structures also incorporate aluminum cans and glass bottles, effectively reducing waste by repurposing it into construction materials. The process of utilizing reclaimed materials not only minimizes landfill use but also provides a unique aesthetic, with walls often featuring exposed cross-sections of colorful glass bottles.
Natural Building Techniques
Beyond recycled goods, Earthships leverage local natural resources such as adobe, cement, stucco, and wood in their construction. This diversity in materials allows for the adaptation of one's own Earthship home designs to various environmental conditions and landscapes.
Following natural building techniques, these materials are selected for their inherent properties, such as thermal mass or insulation, as well as their availability.
Tire Walls and Insulation
Tire walls serve a dual purpose in Earthships. Firstly, the densely packed earth within provides exceptional insulation, essential for the passive solar heating design that they are known for without the need for conventional heating. Secondly, the tire walls constitute a significant portion of the structural support for these homes. Due to the mass and arrangement of the earth-packed tires, these walls naturally regulate indoor temperature, keeping it warm in winter and cool in summer.
Energy and Utilities
With your own Earthship home, you can integrate sustainable solutions for water, electricity, and waste management, reflecting the commitment to living off the grid and minimizing environmental impact.
Water Collection and Management
Earthships employ a Water Organization Module (WOM), which is central to their design. Rainwater is harvested from the roof, funneled into cisterns, and becomes the primary water source. This system often incorporates a multi-layer filtration process that includes a water pump and filters to ensure water quality.
After initial usage, the water becomes 'greywater' and is channeled into indoor gardens, which provide food and also treat the water. This treated greywater can then be reused for toilet flushing.
Rainwater harvest: Captured from the roof and stored in cisterns.
Greywater treatment: Indoor botanical cells purify greywater for reuse.
Own Electricity Generation
Electricity in an Earthship is typically generated through renewable sources like solar panels and wind turbines. These are part of the Earthship's Power Organizing Module (POM), which manages and distributes electricity.
The electricity is stored in deep-cycle batteries, ensuring a continuous power supply even without immediate sunlight or wind. This approach allows them to generate and operate their own electricity with greater independence from conventional power grids.
Solar power: Provided by solar panels installed on the Earthship.
Wind power: Augmented by wind turbines when available.
Waste Treatment Systems
Waste management in Earthships incorporates a Contained Sewage Treatment system, where solid waste is contained and managed on-site. Liquid waste is typically separated and treated through botanical plant cells, contributing to the water treatment process. These systems are designed to reduce pollutants and recycle waste effectively within the Earthship's closed environment, reinforcing the sustainability of the living space.
Sewage treatment: Through botanical cells and on-site systems.
Solid waste management: Environmentally contained and processed.
