A few weeks ago, the USGBC, ASHRAE, and IESNA announced that they had collaborated and released Proposed Standard 189P, Design of High-Performance Green Buildings Except Low-Rise Residential Buildings, for public review and comment. Note that this is not a green building rating system but rather a set of criteria that is designed for municipalities to incorporate into their local building codes in order for officials to grant certificates of occupancy (a vastly different scheme than incorporating LEED by reference into those same codes).
The energy requirement for 189P is a minimum thirty percent reduction (in energy cost and CO2 equivalent) over ANSI/ASHRAE/IESNA Standard 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings. 189P also requires on-site power generation- the standard will demand that buildings produce a certain minimum percentage of peak electrical demand through photovoltaics or other similar systems.
189P will only be available for your review and comment until the public period ends on July 9. You can access the document (note that it’s over 200 pages in .pdf) here.
