• Rating System Overview - The National Green Building Standard (ICC 700-2008) is the first residential green building rating system to undergo the full consensus process and receive American National Standards Institute (ANSI)  approval. The four threshold levels - Bronze, Silver, Gold, and Emerald - allow builders to achieve entry-level green building, or the highest level of sustainable "green" building incorporating energy savings of 60% or more.  Single-family & multi-unit homes, residential remodeling projects, and site developments are all covered in the Standard.  The standard covers seven areas: lot design and preparation; resource efficiency; energy efficiency; water efficiency; indoor environmental quality and comfort; operation, maintenance, and homeowner education; and global impact.  Note: the predecessor voluntary Green Building "Guidelines" will be phased out in late 2010, to be entirely replaced with the National Green Building Standard.
