Durisol ICF lowers the embodied energy of a dwelling.

Stuart Staniford at the Early Warning blogspot discusses the reduction in Embodied Energy a Durisol Foundaiton represents in a low embodied energy dwelling.  In his case study, the use of a Durisol ICF foundation over a conventional concrete foundation improved the "net carbon emissions" by 100%.

His analysis showed the the original carbon emissions associated with the foundation in the dwelling he modeled dropped from aprox 7.5 tons with no opportunity for sequestered carbon to just under 7 tons but now with the ability to also sequester close to 1.75 Tons.
