Hello, It seems to me I read at some point in time that the CaGBC wanted to see a minimum measurable benefit for Innovative Strategies. (Note: I'm not asking about Exemplary Performance where you are achieving the next incremental threshold.) I'm thinking, for example if you were incorporating an innovative waste heat recovery system then they may require (or at least suggest) that it achieve at least the equivalent of one EAc1 point in energy savings. This is a LEED 2009 project. The Reference Guide simply says that strategies are to have "significant, measurable environmental benefits...".
Hi Aaron,
I am not aware of any written guidance on what comprises a "significant measurable environmental benefit".
Speaking as an applicant, and not a reviewer, my understanding is similar to yours that demonstrating equivalence with an existing credit is useful. It should also be for a measure that is not accounted for in the system - in the case of your waste heat recovery example, if your energy model is already rewarding you for that measure, then the ID is not likely to be awarded.
The CaGBC did issue an ID credit catalogue for version 1.0.

These might not apply to version 2009, but give a reasonable idea of precedent ID credits.
