Hi, I am working on a project in Argentina. I've loaded the ET0 and rainfall data from official sources and I get a total water savings over 101% in the LEED Water Savings Calculator, as my project is outside the US and can not use the Water Sense tool . Reviewer comments that this can not be possible.
The site is comprised of a set of intensive green roofs and terraces only and we only irrigate a small portion because in this climate, with the correct planting selection (all hardy groundcovers with a value of 2 in the Landscape Coefficient)
I have tried separating the irrigated and non-irrigated areas in two different calculators and still get the over 101% in the irrigated area (drip irrigation from rainwater harvesting set there just because is the garden of the head of the company and we wanted to have a safe for plants looking great all year-round)
Has anyone ever encountered this problem?
Thanks!!
