Integrative Process Credit

For BD+C: What do they mean by "cascading" in the phrase - "demonstrate how at least one on-site non-potable water supply source was utilized in cascading ways to reduce the burden on municipal supply"? For ID+C: The BD+C Integrative Process credit has been re-worked very awkwardly/problematically into the ID+C Integrative Process credit. The ID+C credit needs a rehaul specific to ID+C. After many in depth read-throughs, it appears that what the ID+C credit is asking for is: 1.) Show an analysis of how the project "site/building" was chosen. ONCE THIS SITE HAS BEEN CHOSEN [this crucial line is missing] 2.) Analyze 2 separate sets of energy-related systems for the space that has been chosen. [NOTE - they should delete the section on Basic Envelope Attributes and "elimination/down-sizing of building systems because CI projects typically have no control over these items] THEN COMPLETE ONE OF THE FOLLOWING OPTIONS TO OBTAIN ONE POINT, OR BOTH OF THE FOLLOWING OPTIONS TO OBTAIN 2 POINTS. [this important language is also missing] 3.)Analyze and document Option 1 / Option 2 An overall comment for this credit is that the separation of Discovery / Implementation is confusing. The language should be simplified. A possible way to simplify is to say - "analyze and document the following outlined process:" ....and then list what they want the team to do. I hope this "translation" helps out other readers! I find it very frustrating the amount of time we're spending "translating" what on earth this stuff means because it's so poorly written.
