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?

NC-v4 WEp1:Outdoor water use reduction

Monthly Evapotranspiration Rate

Hi

Our project is located outside the US and so we're applying the  FAO ETo calculator: http://www.fao.org/land-water/databases-and-software/eto-calculator/en/.

I found the ETo calculator provides results as daily ETo (mm/day) and not as monthly ETo (mm/month) as per the LEED 'Baseline Calculation' tab in the LEED v4 Outdoor Water Use Reduction Calculator. How did you convert this to monthly rates? Is it as straight forward as multiplying by number of days per month?

Thanks

Dear Senna,     You can also use IWMI (International Water  Management Institute) to get the ETo data in mm/day. Following is the link for the website : http://wcatlas.iwmi.org/   You have to make an account first, and then after log in you can input the longitude and latitude of your project to get the ETo data (mm/day).   Thanks and regards.
