FAQs about WEp1 :

The EPA WaterSense methodology and calculator allows only certain types of irrigation to be assigned to certain vegetation types. Why is this and won’t it skew results?

What if we just have a little green area on our rooftop? Is there a minimum amount of landscaped area to earn the prerequisite and credit?

Hi Jose, There is no minimum landscaped area required to comply with the Outdoor Water Use prerequisite or credit. If the site does not require irrigation the project will automatically earn the prerequisite and points for the credit. Ensure you choose the right option within the prerequisite/credit that fits the irrigation needs of your project. Option 1 is better for projects that do not need permanent irrigation beyond an establishment period, and Option 2 should be chosen if there are irrigation needs on site outside of an establishment period. I hope this helps!
