A new course for urban de-creasing earthship as a g-local pattern of land "en-velope and conservation"

"Earthship" can be considered an alternative dwelling approach based on passive houses made of earth and poor materials - mostly recovered. Its shape is strongly characterized and recognizable by some invariants (location, exposure, the conservatory) that give it a specific cultural and formal identity. It can be implemented in urban and land policies as a way for reducing the environmental pressures, spreading an earth/sun-based building culture, integrating ecological issues in economy. This experimentation aims at verifying the integration of an earthship-based settlement pattern in a possible urban de-colonization process within a neighborhood of Comiso (RG) - Italy. It envisages some different layouts composed by three dwelling types, and combines a cost-revenues analysis with some environmental indicators.
