Re: GSBN:Re: A question about quantification of carbon sequestration in a bale and bale structures bale and bale structures

If Robert Wimmer is not yet a member of GSBN I would like to propose
him as a member. He is most probably the strongest advocate for SB
building In Austria and his institute GrAT is doing invaluable work for
the International SB community. They have doen extensive testing and I
am sure they can give quite accurate numbers regarding the ecological
footprint of SB.

developed the concept of the factor 10 house. A building that uses 10
times less resources then conventional building technology. A recent
project completed in 2005 is the S-house a zero energy house it uses
less energy then it creates. In this case sequestration becomes quite
important as building becomes the main negative ecological impact the
building has on the environment.

My thoughts are in harmony with all who have commented so far.  This
discussion is helping me think about the question in more depth.  I
with David that we can't ignore the little things.  Although cases
vary, little things can sometimes add up rapidly.  For example, while
argued that the amount of carbon in the bales is fairly small, David
pointed out that we might compare that to burning the same straw.
mentioned comparing SB to the carbon used when employing other

When we compare building with steel or brick and burning several tons
straw, to building with straw and (hopefully) not burning that straw,
the carbon sequestration embodied in the building materials choice is
multiplied.  Using Andre's figures, choosing to build with straw locks
more than ten times the carbon that is simply contained in the bales.

All of which makes David's job harder, because he now has to figure
out the
relative carbon impacts of building with SB versus each alternative.
