The currently mostly inefficient resource management neglects valuable existing stocks, and grey
energy and emissions contribute to a building sector misaligned with climate goals. Amid these
challenges, rammed earth, an ancient material, is experiencing a sustainable construction resurgence by transforming under-utilized non-hazardous soil excavations into a building material. However, traditional on-site fabrication is expensive and labor-intensive. The investigation of four already existing methods of prefabrication combined with requirements in sub-urban residential housing generates a strategy of how the use of the material can be scaled up considering aspects of efficiency, circularity, and aesthetics.
