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

Calculations for Projects outside USA

Hi! How is that projects outside USA may use the Excel (in the pr and cr resources) or the WaterSense tool if the Zip Code must be introduced?. We have our own Eto Data and as we see we are not able to use de WaterSense Tool as it is only set for locations in USA and it does not work with International System which is as I remember well one of the exciting news about the globalization of LEED. Thanks so much for any help provided.

The "International Tips" section of the LEEDv4 Reference Guide indicates that projects outside the U.S. should be able to input their ETo data directly into the tool. I downloaded the latest version of the tool from EPA's website (http://www.epa.gov/watersense/water_budget/) and Step 1B on the first tab asks for the average monthly reference ETo - you should be able to enter your value there regardless of your project's location.

Hello, I wonder if there is any updated guidance on this. I realised the comment above is 8 years old. I downloaded the WaterSense tool but it's not possible to enter the ETo value on the first tab or any tab. I searched through alternative compliance paths but there is none on this topic. Thanks for your help.

Hi Lidia, The calculator for international use is not the WaterSense tool. It is simply called the Outdoor Water Use Reduction calculator and is the first download option on the Resource tab of the online reference guide. You can enter your ETo values directly in that one.
