Earth USA 2019 was our 10th International Conference on Architecture & Construction with Earthen Materials. The formal conference took place from Friday, October 25 to Sunday, October 27, 2019 at the Scottish Rite Center's Alhambra Theater in Santa Fe, New Mexico. Earth USA 2019 indicated a wider field of interest than previous conferences and included adobe, rammed earth, compressed earth block (CEB) and monolithic adobe (cob). Any material or method that uses clay as a binder was considered. Activities included:

  • Three days of podium presentations and poster sessions on topics related to the current state of architecture and construction with earthen materials.

  • Friday evening Speaker Meet & Greet for all conference attendees sponsored by The Earthbuilders' Guild.

  • Tours to local earthbuilding sites of interest in and around Santa Fe, New Mexico.
