It seems like the value of each credit has yet to be determined. I thought there would be some sort of value comparison released with all future versions of LEED, similar to the 2009 version. Does that mean point values will just be slipped in without public comments?

Keep in mind there is at least one more public comment period, and possibly more.I haven't heard USGBC explain this, but my guess was that it was considered a lower priority to assign points at such an early stage, when credits could still come and go. It seems like something for later in the process, when the credits are set and it's time to haggle over what's worth more. Also, in the back of my mind I recall hearing that USGBC is developing its own weighting method (which I'm sure will be shared with the public, hopefully for comment). The weighting for LEED 2009 was based on an EPA method.

Each rating system will go through a weightings process similar to LEED 2009. In LEED 2009, the U.S. Environmental Protection Agency’s Tool for the Reduction and Assessment of Chemi-cal and Other Environmental Impacts (TRACI) categories were used to determine a relative weight of each credit as compared with the others within a given rating system. For the update to LEED, USGBC has developed a number of impact categories more closely aligned with our mission that will inform the point allocation across the rating system. This process will take place between the first and second public comment periods.
