[GSBN] Fwd: Embodied energy comparisons: SB vs Stick-built

 Small houses seem to work out best in the long run when heating & cooling
is conventional, even though their relative initial cost may be greater.
It's hard to imagine a larger building sequestering more CO2 than a small
house with an adjacent grove of trees.

A green roof, besides contributing significantly to summer cooling,
sequesters some CO2.  Do you have a idea of the percentage of CO2 that is
sequestered in a typical garden?  Since the plants usually end up rotting,
albeit for reuse,  this seems a different case from trees.

*(As a complete aside, does anyone have a**guess if/how much people would be
prepared to pay for such a gadget -*
*that calculated the CO2 impact of a particular house design?)*

Energy 10 software includes a calculation of the annual emissions of a
building, and they might be interested in incorporating such impacts into a
"life cycle *environmental* cost" calculation.
