Earthships are primarily designed to work as autonomous buildings using thermal mass construction and natural cross ventilation assisted by thermal draught (Stack effect) to regulate indoor temperature. These are generally off-the-grid homes, minimizing their reliance on public utilities and fossil fuels. Earthships are built to utilize the available local resources, especially energy from the sun. In this age of increased garbage accumulation, it is essential to reduce the waste clutter and earthships are an ideal option. This paper discusses the construction aspects, merits and demerits of earthships.
