Dear all,
I am performing the calculation for the Water Outdoor Prerequisite, with both excel for a Project located in Italy (Rome):
1. Water budget tool (downloaded from EPA)
2. v4_Outdoor Water Use Reduction Calculator
I get a negative value for LWR, I suppose that for this reason I don't need any irrigation, is it true? Does anyone have experience on that?
Thanks!

A negative value for LWR likely indicates an error in data entry to the calculator. The values for both LWA and LWR should both be 0 or higher. With additional information, we may be able to help you pinpoint the source of the error.
