Schools-2009 WEc1:Water Efficient Landscaping

Reference Evapotranspiration Rate

When LEED ask for the reference evapotranspiration rate (ETo) for the month of July in the WEc1 form, does it mean I should provide the daily ETo for the month of July (ETo rate per day), or should I provide the monthly ETo rate on July, i.e. (daily ETo) X 31(days in July)? Thanks :)

It's the Et0 for the month, which you will need to fill in there. Her are the national and international resources for it: http://bit.ly/sp275F http://bit.ly/ySBA2T

The IWMI website no longer has the IWMI Online Climate Summary Service Portal with the ETo values, what is the new source you are using?

Try this link for ETo data worldwide: https://aquastat.fao.org/climate-information-tool/ (There's a map you can click on to get the data about your selected location.  Or you can enter your Lat./Long.)
