Website about ‘Arcology’
Arcosanti is designed according to the concept of arcology (architecture + ecology), developed by Italian architect Paolo Soleri. In an arcology, the built and the living interact as organs would in a highly evolved being. This means many systems work together, with efficient circulation of people and resources, multi-use buildings, and solar orientation for lighting, heating and cooling.
