The HPSB Guiding Principles for New Construction and Major Renovations
The Guiding Principles for New Construction, as mandated by Executive Orders 13514 and 13423, address water with a number of key directives. As per EISA 2007, thirty percent of the hot water demand should be met using the installation of solar hot water heaters when lifecycle cost-effective. Section III of the Guiding Principles addresses the need to "Protect and Conserve Water" in the facility’s indoors, outdoors, and processes. Guidance sets an aggregate goal at a minimum of twenty percent and at a fifty percent reduction in potable water use for inside and outside the facility, respectively. The implementation of water-efficient products containing EPA’s WaterSense label are encouraged.

The HPSB Guiding Principles for Existing Buildings
For existing facilities, the Guiding Principles requires a twenty percent reduction in indoor potable water use compared to 120 percent of the Uniform Plumbing Code (UPC) 2006 baseline or the specific buildings water use data in 2003. Potable water for irrigation must be reduced by at least fifty percent of the 2003 baseline. The installation of water meters for building sites with significant indoor and outdoor water use is further encouraged. Deploying lifecycle cost effective water conservation measures and water-efficient products with EPA’s WaterSense or similar label is explicit.

Executive Order 13514 (2009)
Executive Order 13514 expands the water efficiency requirements of EO13423 and EISA 2007 by requiring Federal agencies to reduce potable water consumption intensity two percent annually through fiscal year 2020, or 26 percent relative to a FY 2007 baseline. EO 13514 further requires a reduction in agency industrial, landscaping, and agricultural water consumption by two percent annually or twenty percent by the end of FY2020 relative to a 2010 baseline. Agencies are also encouraged to identify, promote, and implement water reuse strategies consistent with state law that limits the need to consume potable water.

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.

Executive Order 13423 (2007)
Executive Order 13423 requires Federal agencies to reduce water consumption intensity (measured in gallons per square foot) by two percent annually through the end of FY2015, which is equivalent to a sixteen percent overall reduction from the defined 2007 baseline. Federal facilities are further directed to conduct annual water audits of at least ten percent of facility square footage and to conduct these audits at least every ten years. EO1314 also promotes the purchasing of water efficient products and services as well as WaterSense labeled products.
