Feasibility of translating earthships in Africa and future design considerations

Abstract

Earthships are passive solar buildings with renewable power, water harvesting, and sewage systems, designed to be off grid with minimal reliance on public utilities, and use recycled and natural materials. Due to high initial capital cost and resources needed, earthships have primarily been implemented in developed countries. However, the self-sufficiency earthships offer through their subsystems presents an opportunity for resource-constrained environments. Three earthship projects have been developed in Africa, each serving a unique purpose and overcoming different obstacles. Through earthship design principles, technical reports, and lessons learned from each project, this paper aims to outline design considerations for those who are interested in implementing an earthship in Africa.
