Guiding Principles for Sustainable Federal Buildings

The Guiding Principles for Sustainable Federal Buildings were updated by the Council on Environmental Quality on February 26, 2016.

  • Existing Buildings: Twelve out of 18 metrics are required—eight that are specified as required plus four additional. Any metric determined to be “not applicable” cannot be counted toward the 12 required.
  • New Construction or Modernization: For new construction, metrics one through 20 are required. For modernization, metrics one through 18 and 21 are required, as specified, below.

For more information, read Guiding Principles for Sustainable Federal Buildings and Associated Instructions, Determining Compliance with the Guiding Principles for Sustainable Federal Buildings, and the 2016 Guiding Principles for Sustainable Federal Buildings Updates Crosswalks: Existing Buildings and New Construction and Modernization.

Existing - GP III: Protect and Conserve Water
Guiding Principle Full Text
07. Indoor Water Use

A. Install building-level water meters, reduce water use 20% below FY 2007 baseline, and use water efficient products, or

B. Install building-level meters, conduct an analysis of water use, identify and repair leaks, eliminate single pass cooling, optimize cooling tower operations, and use water-efficient products. [Required]

08. Outdoor Water Use

A. Install water meters for irrigation systems serving more than 25,000 square feet of landscape, and

B.  Either:

i. Use water efficient landscaping, or

ii. Limit potable water use for irrigation to 50% or more below conventional practices using methodologies from (but not the numeric requirements contained in) ASHRAE standard 189.1-2014 section 6.5.1, or current comparable standard, to calculate water use of conventional practices.

09. Alternative Water

Consider alternative sources of water where cost effective and permitted by local laws and regulations.

10. Stormwater Management

Employ strategies that reduce stormwater runoff and discharges of polluted water off-site to protect the natural hydrology and watershed health.
