Proposed Standard 189P (USA)

"Being developed by a partnership between the USGBC, ASHRAE, and IESNA ... say the baseline standard, which will apply to new commercial construction and major renovations, will be fleshed out by 2007.

The new standard will be largely based on LEED, with prescriptive measures for environmental performance drawn from its five categories.

code agencies could adopt Standard 189P as a baseline, while mandating additional sustainability measures as they see fit. This would relieve states and municipalities from needing to draft special legislation to mandate green buildings by, for instance, referencing LEED or other voluntary rating systems."

"Currently the standard is open for public comment and comments will be accepted through July 9, 2007 at www.ashrae.org/publicreviews. The committee plans to release the standard by late 2007. Upon completion, Standard 189 will be an ANSI-accredited standard that can be incorporated into building codes...(just as Standard 90.1... has been almost universally adopted as a baseline standard for energy efficiency)"
