I think you have ASTM E2392 / E2392M – Standard Guide for Design of Earthen Wall Building Systems (that David Eisenberg initiated around 2001, and Bruce King lead the revision of in 2010)<BR>
<BR>
I also have 12 US Straw Bale codes (State, County or City), the Belarus SB Code, the New Zealand SB BRANZ Bulletin, the Denmark Halmhuse document (mostly in Danish) which I understand is a de facto code<BR>
<BR>
I also have a few codes or code related documents on bamboo.<BR>
<BR>
As far as I know, most if not all of the above codes or official guidelines are in effect (or in the case of the first three are, or will soon be, in the “International” model codes)<BR>
<BR>
So I will e-mail you the bullet point items, and if requested I can do the same for any other item I mentioned (except possibly the ASTM Standard which strictly speaking is not transferable).<BR>
<BR>
If anyone else is interested in any of the above, please let me know.<BR>
<BR>
<BR>
Note that today is Mother’s Day (at least in the US) (Happy Mother’s Day everyone!) and Bruce may have a full day planned with his lovely wife Sarah, which could affect his ability to respond before your meeting tomorrow. I have a full day planned for my lovely wife, . . . but she’s not awake yet (!).<BR>
<BR>
Best of luck with your meeting.<BR>

Sorry to push you, but please will you send that survey of earthen building standards and codes that you said you did about 6 years ago.<BR>
<BR>
I am busy agitating the powers that be – and meet with a group of stakeholders tomorrow including our Standards Bureau - and so really need as much info as I can get my hands on.<BR>
<BR>
Thanks Graeme for your update about the New Zealand codes and their technical committee. <BR>
<BR>
Any other inputs are most welcome.<BR>

I did a complete survey and review, about 6 years ago, of earthen building standards and codes around the world. Be glad to share it, but am super-swamped for the next week and It will take a bit of digging to find. Since then, I know of several efforts to develop cob standards, not to mention Martin Hammer et al recently bringing straw bale into the International Building Code.<BR>
