We're in the middle of our response to the reviewer's comments on our initial submission (so our performance periods ended a few months ago).
Let's say we decide now that we should change out some shower heads and faucets in old fixtures, and do that. Further, let's say that when we enter those new flow values in the form on line, and it shows we reduce by a % that gets us the more points. If we describe this in a narrative, then re-submit, will GBCI give us the extra points now eventhough we didn't have the new fixture trim until after the Performance Period? The lead in paragraph for WEc2 says "during the performance period", however, one could argue that the intent of a performance period is to know it works, and, perhaps, document it works. With new trim for lavatories and showers, there's nothing to prove, once it's in the flow will be what it is designed by the manufacturer to be, not otherwise (reduction is assured).
Thank you
