California Institute of Earth Art and Architecture

The California Institute of Earth Art and Architecture (Cal-Earth) is a non-profit educational organization that focuses on teaching sustainable building techniques using natural and local materials, primarily earth. Founded by Nader Khalili, it emphasizes creating affordable, eco-friendly homes through innovative methods like "superadobe" architecture, which involves filling long bags with soil to form durable structures. Cal-Earth promotes environmentally conscious design and provides training, workshops, and research to help individuals and communities build resilient, low-impact dwellings that harmonize with the landscape.
