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?

Irrigated areas and vegetated non-irrigated areas - How to include in calculator?

The reference guide's step-by-step language says:

If only part of the lot is irrigated, complete the calculation twice—once for the irrigated section, and again for the unirrigated area—and sum the results.

What exactly is meant here -- do we complete 2 separate calculators (one for irrigated areas, one for non-irrigated), then a summay table of the info?  Do we use a weighted average of the percentage?  When we enter the non-irrigated area in the calculator, do we enter it as irrigated?  Can someone please clarify?  Thanks!
