Pilot-Credits WEpc115:Whole Project Water Use Reduction

Required documentation for submission

Hello.

We are targeting this pilot credit while having no irrigation requirements for the outdoor water use credit (full points gained) and having achieved all the points for the indoor water use credit as well. We are planning to submit the following for the pilot credit: credit survey submission, annual outdoor water use reduction calculator, whole project water use reduction calculator, water balance model and rainwater harvesting system drawings and specs. Is there anything else that should be submitted for this?

Thank you very much in advance.

In addition to the information you’ve provided, we also need supplemental documentation for all uses of process water, including ice machines, laundry systems, and any other applicable equipment. We also need to include participation in the LEED forum.

Is it necessary to upload the documentation already provided within the Indoor Water Use Reduction Prerequisite and Outdoor Water Use Reduction Prerequisites? Such as the Indoor and Outdoor Water Use Reduction Calculators, Plumbing Schedules/Cutsheets, and Landscape Irrigation Plans? Or have others been successful simply pointing the reviewer to these resources within the Whole Project Water Use Narrative? It seems redundant to re-upload these documents for the purposes of documenting WEpc115?

We don't upload the Prerequisite calculators but we have started to upload a process water document/calculator that we have created to show how we came up with the process water numbers.
