Plumbing Fixtures

Design Guidance

Overall Strategies

Water consumption may be reduced by installing or retrofitting fixtures that are more efficient than code. New technology has resulted in reliable low-flow fixtures. However, always ensure the building pressure is adjusted and in compliance with the plumbing fixture manufacturer's recommendations in order for fixtures to work optimally.

Green Tips

  • Install new plumbing fixtures that are durable, effective, and water-efficient.
  • Retrofit existing plumbing fixtures with equipment to maintain functionality but reduce water use.
  • Provide water-efficient showers for staff that bicycle or run to work.

Guiding Principles

  • Environmentally Preferable Product ( Guiding Principles, Executive Order 13693 [EB, NC])
    Section: V. Reduce Environmental Impact of Materials

    Use products that have a lesser or reduced effect on human health and the environment over their lifecycle when compared with competing products or services that serve the same purpose. A number of standards and ecolabels are available in the marketplace to assist specifiers in making environmentally preferable decisions. For recommendations, consult the Federal Green Construction Guide for Specifiers.

  • Water-Efficient Products ( Guiding Principles, Executive Order 13693 [EB, NC])
    Section: III. Protect and Conserve Water

    Specify EPA's WaterSense-labeled products or other water conserving products, where available. Choose irrigation contractors who are certified through a WaterSense labeled program. http://www.epa.gov/WaterSense /http://www.epa.gov/WaterSense/products/

  • Measurement of Water Use ( Guiding Principles, Executive Order 13693 [EB])
    Section: III. Protect and Conserve Water

    The installation of water meters for building sites with significant indoor and outdoor water use is encouraged. If only one meter is installed, reduce potable water use (indoor and outdoor combined) by at least 20% compared to building water use in 2003 or a year thereafter with quality water data. Employ strategies that reduce storm water runoff and discharges of polluted water offsite. Per EISA Section 438, where redevelopment affects site hydrology, use site planning, design, construction, and maintenance strategies to maintain hydrologic conditions during development, or to restore hydrologic conditions following development, to the maximum extent that is technically feasible.

  • Indoor Water Use ( Guiding Principles, Executive Order <span>13693</span> [EB])
    Section: <span>III. Protect and Conserve Water</span>

    Guiding Principles for EB: “Employ strategies that measure and minimize water usage, including:
    (i) Conduct an analysis and take action to monitor facility water use and identify and implement conservation opportunities.
    (ii) Purchase water conserving products, including WaterSense and FEMP-designated products, as required by statute.
    (iii) Install building level water meters to allow for the management of water use during occupancy, including detection of leaks.
    (iv) Optimize cooling tower operations.
    (v) Eliminate single pass cooling.”
    Determining Compliance: “Install building level water meters, reduce water use 20% below FY 2007 baseline, and use water efficient products, or 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.”

    Guiding Principles for NC: “Employ strategies that minimize water use and waste, including:
    (i) Purchase water conserving products, including WaterSense and FEMP-designated products, as required by statute.
    (ii) Install building level water meters to allow for the management of water use during occupancy, including detection of leaks.
    (iii) Optimize cooling tower operations.

  • Material Content and Performance ( Guiding Principles, Executive Order <span>13693</span>&nbsp;[EB])
    Section: V. Reduce the Environmental Impact of Materials

    From the Guiding Principles for EB: Procure construction materials, products, and supplies that have a “lesser or reduced effect on human health and the environment over their life cycle when compared with competing products or services that serve the same purpose”, including:
    (i) “Use Resource Conservation and Recovery Act (RCRA) section 6002 compliant products that meet or exceed EPA’s recycled content recommendations for building construction, modifications, operations, and maintenance.”
    (ii) “Per section 9002 of the Farm Security and Rural Investment Act (FSRIA), for USDA-designated products, use products with the highest content level per USDA’s biobased content recommendations.”
    (iii) “Purchase products that meet Federally Recommended Specifications, Standards and Ecolabels or are on the Federal Green Procurement Compilation.”
    (iv) Eliminate, to the maximum extent practicable, “ozone depleting compounds and high global warming potential (GWP) chemicals where EPA’s SNAP has identified acceptable substitutes or where other environmentally preferable products are available” during construction, repair, or replacement at the end of life.
    Determining Compliance: “Procure products that meet the following requirements where applicable: (A) RCRA section 6002, and (B) FSRIA section 9002, and (C) Federally Recommended Specifications, Standards and Ecolabels or are on the Federal Green Procurement Compilation for other green products, as appropriate, and (D) Avoid ozone depleting compounds and high GWP chemicals.”
