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

<BR>
Is this the best use of this material?<BR>
Are we diverting/consuming a material from some other more important use?<BR>
<BR>
This is sort of the flip side of recycling- removing things from the market that have other uses. The poster child for this kind of dilemma is crude oil. Oil pundits like to say it has a million different uses, from pharmaceuticals to fertilizers to building materials. Instead, we burn 99% of it, getting the lowest possible use from an amazing material.<BR>
<BR>
Right now, I look on ethanol this way. To produce a marginal (perhaps negative) energy source, we have impacted food supply and general wealth and health in Mexico among other places.<BR>
<BR>
I don't have an example in mind for this kind of misuse of a material as it relates to the building industry. Perhaps others can suggest one.<BR>

significance as life-cycle energy use, I would suggest that any<BR>
materials or forms of construction be evaluated on at least these<BR>
areas:<BR>
<BR>
<BR>
? Does the material contribute structurally<BR>
? Does the material contribute thermally (insulation)<BR>
? Does the material provide thermal storage (mass)<BR>
? Does the material provide fire safety<BR>
? Does the material contribute to the local economy<BR>
? What are the manufacturing environmental costs<BR>
? What are the transportation and wastage environmental costs<BR>
? Is the material a by-product, waste-product, or recycled<BR>
? Is the material bio-degradable, recyclable or land-fill<BR>
? Is the material toxic in manufacture, use or disposal<BR>
? What is the expected life-span of the system (resistance to<BR>
environmental damage)<BR>
Feel free to add.<BR>
