The credit is pretty vague about defining the "maximum number of cycles without exceeding any filtration levels". Does this need to be exact (to the gallon over a year)? For example, one of my current projects would be limited by Cl- at 6.25 cycles of concentration before reaching the 250 ppm limit. If they're at 6.0 is that good enough? There doesn't seem to be any quantification of "maximum". Within 10%? 1%? Has anybody gotten feedback on this one? Hopefully LEED 4.1 addresses this credit a bit or at least expands the reference guide because it currently leaves a lot undefined.
