Hi everyone! We are working on the certificacion of a major renovation building. We are willing to get this IP credit but have some doubts. 1) What are the differences between v4 and v4.1 version of this credit?

2) What documentation is required to achieve v4.1? Since, there are no resources on USGBC website.

3) Does anyone have some samples on v4 worksheet?

4) What happens if, for example, in the discovery phase we have identified 2 water demand reductions and later, during construction, we could only achieve 1? Is this valid? 

Thank you for your time!
