Haiti Communitere earthship living space
The earthship living space was built at Haiti Communitere as a response to the 2010 earthquake. It serves as a demonstration for how homes can be built from waste material like tires, plastic bottles, and rubble from the earthquake. The base of the earthship is made with tires stacked seven high within the walls. Above the tires are the plastic bottle walls. The dome roof was made with steel bars along with with shredded cardboard and styrofoam in rice bags and plastic bags for insulation. The earthship incorporates concepts like temperature regulation, solar energy, sewage treatment, upcycled materials, water harvesting, and food production. A solar panel charges a battery, which provides the necessary energy for the earthship living space. The other mentioned concepts are discussed under the images in the gallery. For an animated explanation of the process please see the #Videos below. The total project cost was about USD$4000, and it took around 20 people 10 days to construct the entire structure with pre-prepared materials. The structure used about 10,000 plastic bottles, and just under 100 tires that would have otherwise remained in the waste stream.
The earthship design incorporates passive rainwater catchment. All of the water that falls on the roof of the main room, the archway, or the restroom is guided to a water storage tank by the contours of the roof. That water can then be collected from a spigot and be used for toilet flushing, showering, or any other necessary task.
The toilet is flushed with water from the shower greywater basin. The flushed water enters a blackwater tank and overflows into a different garden basin where it provides nutrients and water to plants. If that basin fills there is a third garden bed that serves as an overflow basin for the blackwater.
The first video explains the design and some of the construction process for the earthship structure. The second video provides a view of the wall from inside the Earthship structure. The wind blowing through the trees outside causes the light to flicker through the bottles.
