Entities pursuing green building standards include USGBC, ASHRAE and IESNA, which [announced that they will co-sponsor development] of "ASHRAE/USGBC/IESNA Standard 189P: Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings. The three organizations will develop the new standard through ASHRAE’s ANSI-accredited process, creating a standard that could be incorporated into building codes, including other ASHRAE/ANSI standards. The standard, which is on the fast track to be rolled out in 2007, will apply to new commercial buildings and major renovations. It is expected to be modeled after the LEED Rating system, including prescriptive measures drawn from all five LEED categories: sustainable sites, water efficiency, energy and atmosphere, materials and resources, and indoor environmental quality.".
Standard 189 is intended to be incorporated into US building codes.
