Inquiry

Our project involves 7 buildings around a university quadrangle site. In order to reduce irrigation water consumption, our design strategy is to reduce the area of irrigation by only irrigating the turf grass areas that will be exposed to high foot traffic. In all other landscape areas, we are using low-maitenance native plants and providing no irrigation.\n\nOur calculations will show that total irrigation water consumption has been reduced by more than 50% versus a Baseline Scenario that irrigates all landscape areas on the site.\n\nWE 1.1 states that the goal of this credit is to reduce potable water used for landscape by 50%. But the criteria only lists two methods for achieving this goal - high efficiency irrigation technology or recycled rain/site water. Our design strategy achieves the 50% reduction goal by limiting the quantity of area irrigated. Is there any reason this strategy would not count for this LEED credit?
