Are Other So Called "Green Building Sytems" truly "Built Green"?

I see local builders claiming that their homes are "Green" homes, or that they use "Green Building Technology", but are they really "Built Green"? When you study their building techniques you find that they are only building homes that are more energy efficient, not really "built green"! In virtually all cases they still use lumber (trees), and actually use more lumber since most claim 2x6 wall studs, and they also use Low E glass and high R-value insulation. Yes, they are providing more energy efficiency, but by using these materials the homes are not truly "Built Green"! To be truly "Built Green", a building technology must strive to build with products that do not require the destruction of the very thing (trees) that is required to reduce greenhouse gases. In fact, many cities are now requiring that all builders utilize green building designs. Shouldn't they also require the builders to actually "Green Build" new homes as well? Superior Green Building Systems does make homes "Built Green", by utilizing recycled materials and agricultural by-products, in addition to creating extremely energy efficient and less expensive homes in the process. SGBS - the ONLY system that's truly "Built Green" and the best alternative for the future.
