Hi,
does anyone know if it is possible to claim water savings whenever real irrigation systems have distribution uniformity (DU) higher than the LEED default (e.g. Rotor with DU=80%, default=70%)?
I'm not sure if this is possible since Outdoor Water Use Calculator has these cells locked. Shall this be classified as "Additional reduction calculations" in form?

Hi Ricardo,
If your irrigation design meets the requirements of Step 6 you can claim additional savings by following Equation 4:
Step 6. Calculate additional reduction from baseline for smart irrigation controls
Count only irrigation controls whose smart-sensor technology meets the WaterSense criteria. These controls result in an additional 15% reduction that project teams can take from the baseline.
Equation 4.
Adjusted monthly landscape water requirement (LWR) Final LWR = (Prerequisite LWR or adjusted LWR) − (.15 × Prerequisite LWR)
