Dear all

I suggest that Andrew Alcorn be added to this list - he has been  
involved in earth and strawbale building research and design for many  
years and is one of the few researchers I know of who is delving  
deeply into this embodied and related  energy stuff in buildings

In addition it will save me forwarding on loads of emails to him, and  
his replies to you


cheers
