<DIV>Dear all</DIV>
<DIV><BR></DIV>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
<DIV><BR></DIV>
<DIV>In addition it will save me forwarding on loads of emails to him, and his
replies to you</DIV>
<DIV><BR></DIV>
<DIV><BR></DIV>
<DIV>cheers</DIV>
