FAQs about WEc1 :

Do the 30% and 40% reductions need to be achieved prior to the application of alternative water sources in order to earn the credit?

When pursuing Option 2 do I have to use the EPA WasterSense Water Budget Tool or USGBC’s Outdoor Water Use Reduction Calculator?

Does the project site need to have a minimum amount of vegetation in order to pursue the credit?

EBOM-v4 WEc1:Outdoor water use reduction

Option 2 for submetered irrigation

If we install subsystem metering for the irrigation systems to comply with WE credit Water Metering can we still select Option 2 (No irrigation meter installed: Calculated water budget). Alternatively, we cannot select Option 3 (Irrigation meter installed) because historical data are not available since the subsystem metering was installed only prior to commencement of the performance period. Any thoughts?

If you do not have the historical meter data for the required three years, then you can pursue Option 2. The calculated water budget would be utilized for the initial certification and Option 3 would be utilized for recertification. You can find this in the reference guide under Step 4 of the step-by-step guidance.
