Our Story
A group from Central Texas, led by Stephen Colley, decided to form the Earthen Construction Initiative after attending EarthUSA 2015 in Santa Fe, New Mexico. This group envisioned an organization that would be a resource to designers, builders, government agencies, and anyone interested in accurate, science-based information on a range of earthen construction technologies.

What's next?
ECI was established as a 501(c)(3) non-profit educational organization effective February 24, 2016. ECI is dedicated to advancing the appreciation and science of earthen construction through monthly presentations/ demos, guest lectures, workshops, and research. Our recent successes and current initiatives include:
  • City of San Antonio code amendments to address earthen construction;
  • Development of testing standards and best practices;
  • Research on hygrothermal effects on interior air quality.
We also sponsor and support the following organizations and events:
  • EarthUSA biennial conference, Santa Fe, New Mexico.
  • Solar Fest, San Antonio, Texas
  • The Earthbuilders Guild, NM

Moving forward, ECI is working on workshops geared both to families and to construction professionals, and accelerating our research program.
