My background is extensive in natural building over the last 3 decades. I have been a natural building contractor in Colorado and Texas, In charge of R&D department and setting up Education programs for American Clay Enterprises (before the recession in 08). Have published research papers on how earthen building materials control humidity and Temperature in building envelopes. The past 4 years i have been building with Hemp-Lime (hempcrete), now that we can get the base materials sourced in the USA. This is a resent podcase I was interviewed for and is a good over view of where I started this journey and what we need to do to Build Resilience in Housing, I hope y'all enjoy it. https://alexhippenhammer.substack.com/p/beyond-green-natural-building-with
