Guiding Principles for Sustainable Federal Buildings

  • Guiding Principle 3 addresses the need to "Protect and Conserve Water" in facilities indoors and outdoors as well as using alternative water sources.
  • Guidance requires utilizing best practices for water efficient landscaping and water-efficient irrigation strategies to track and reduce outdoor potable water use. Outdoor water meters are also recommended when irrigation systems are greater than 25,000 square feet.
  • Water meters are required inside the facility, as are the use of water-efficient products.

Relation to Water: hot water energy, water harvesting, water protection and conservation, graywater, efficient plumbing fixtures, efficient landscaping, water metering

Energy Independence and Security Act (2007)

The Energy Independence and Security Act (EISA) requires facility managers, as defined by the act, to complete comprehensive water evaluations through retro-commissioning of 25 percent of covered facilities each year, so that each facility is completed at least once every four years. Water efficiency measures were specified, with the promotion of bundling measures into combined projects as a cost-effective strategy to reduce overall energy consumption per square foot by thirty percent by FY2015. Measuring and verifying water savings through metering is also made explicit.
