A part of the Federal Leadership in High Performance and Sustainable Buildings MOU, paragraph III of this January 2006 document requires that Federal facilities employ strategies that in aggregate use a minimum of 20 percent less potable water than the indoor water use baseline calculated for the building, after meeting the Energy Policy Act of 1992 fixture performance requirements. For outdoor water use it promotes the use of water efficient landscape and irrigation strategies, including water reuse and recycling, to reduce outdoor potable water consumption by a minimum of 50 percent over that consumed by conventional means (plant species and plant densities).
