Hello! The calculation of savings due to alternative water sources seems to be missing from the calculator and online form. It seems to me that this must be documented under special circumstances. Am I missing something?

I ran into that same question. I think you're on the right track with documenting it under special circumstances with a narrative and supplemental calculations. And check the USGBC credit library for an updated calculator before you submit your project. They've been making changes and corrections to various templates and calculators as issues are uncovered.

I have the same difficulties with documenting evidence using alternative water sources for indoor water use reduction. The updated calculator was not found in the USGBC credit library. The only way to explain the reduction rate using alternative water sources seems to be through narratives on project's merit. Any update from USGBC on this matter yet?
