I am pretty intrigued by how the first two IP credits have evolved to require setting of performance areas for consideration and then setting up tracking of that performance (in the Implementing Synergies credit). The most intriguing part to me, is that attention is given to environmental performance beyond energy and water, and that there is an assumption that such things as habitat health, soil health, and human performance are trackable.
This is very exciting, and could lead to creation of some real knowledge about extended environmental and human impact of our built environment.
My only concern is that it is unclear, as of yet, how this sort of tracking can be aggregated to be more useful to practitioners.
