Does the storage of rain water contribute to achieve this prerequisite?
The project will irrigate the outdoor vegetation only with rain water. Nevertheless, the water reduction in term of water volume, in comparison with the baseline, is only 16%.
Is it acceptable?

Hi Francesco,
Unfortunately, the v4 reference guide states, "Additional savings gained by using alternative water sources and smart sensor technologies are addressed in the WE Credit Outdoor Water Use Reduction. No credit is given for alternative water sources in this prerequisite." You will need to meet the 30% reduction using the EPA WaterSense tool and then the alternative water sources can be used to demonstrate compliance with the WE Credit Outdoor Water Use Reduction.
Hope that helps!
