On Wednesday, I posited that codifying the LEED rating system, or any other third party green building rating system, is not a viable option for an entire state.  

Why?  Here are three primary considerations:  

1.  There are troubling antitrust issues associated with the LEED rating system.  These antitrust issues are significantly exacerbated by the incorporation of LEED into regulations or building codes.

2.  The LEED rating system was never intended to be codified.  In fact, the LEED rating system is meant to apply to only 25 percent of new construction starts

3.  I believe the USGBC has recognized the problems associated with codification of the LEED rating system.  In response, the USGBC, along with other groups, is quickly pushing along publication of ASHRAE 189.1P, which codifies many of the elements of the LEED rating system.  This is just a hunch, but I anticipate that the USGBC will start urging jurisdictions to adopt ASHRAE 189.1P instead of the LEED rating system.

Can you think of any other reasons?
