G’Day, GSBN —

John Glassford wrote to me asking for some technical reports, in particular the thermal study done at Oak Ridge National Laboratories about 15 years ago.  I can’t find an electronic copy on my hard drive, but hope that one of you do and will load it up on the BuildWell Source here: http://buildwelllibrary.org/building-materials/fibers/straw/strawbale <http://buildwelllibrary.org/building-materials/fibers/straw/strawbale>

We’ve all been in John’s position, and will again:  when the technical stuff you mostly don’t care about or need you suddenly do, and in those moments we all need an easy, accessible place to find it.  That’s why we have the Source <http://buildwelllibrary.org/>   But it is a user based, user-reviewed resource; we count on you to take a moment and upload whatever useful documents you may have so that everybody forevermore all have benefit of them.

Please do take a moment to share whatever geeky jewells you may have — on straw, straw-clay, earthen building, bamboo, or any other part of natural building.  Someone someday will be very grateful that you did, but you can enjoy the warm satisfaction of your own selfless generosity right away!
