CRI at Work

In the past three years, CRI has accomplished much towards our goal of a cob building code.

We have

  • grown our website
  • developed a library of cob information
  • published our first newsletter
  • attended Terra2016 in France
  • presented an EarthUSA white paper
  • collaborated with TEG
  • in-line tested four cob walls
  • out-of-plane tested a cob wall
  • R-value tested a cob wall panel
  • learned to function as a non-profit
  • written and submitted an IRC Cob Construction Appendix Building Code

To support this work, we have held a successful crowdfunding.
With the support of more than 100 donors over the past half year, CRI has raised more than $10,000.
This has brought CRI 1/5 of the way to our $50,000 goal.

This funding is needed to

  • cover the costs of writing the IRC Appendix and Commentary
  • attend and shepherd the code through ICC hearings in May and October of this year
  • complete additional research, development, structural and R-value testing of low-density cob mixes, wall reinforcing, and other code improvements

If you want to build with cob where a building permit is required, then CRI is working for you!
