Water Calculator

Hi Joan - The Total Water Use calculator can be found within the Homes workbook: http://www.usgbc.org/resources/leed-v4-homes-and-multifamily-workbook-sample. This calculator will be updated with improvements for multifamily projects on October 1, 2014.

Sorry if I am posting in the wrong place - but I have a Midrise V4 Water Reduction Calculator Question: It appears as though the Water Reduction Calculator penalizes a smaller landscape area. For example, I entered in a 50% savings on a 1000sq.ft landscape area and a 50% savings on a 20,000 sq.ft. landscape area and the total building water savings % was lower with the smaller landscape area. Perhaps this because v4 combines indoor and outdoor water use reduction - where v2009 did not? Or because it assumes there will be more non-permeable area? If that is the case, does anyone have any experience with a zero lot line project in high density locations being given an exception or relaxation? Thank you! Andriana
