LEED   view pdf

Administered by the United States Green Building Council® (USGBC), LEED® (Leadership in Energy and Environmental Design) is an internationally recognized third-party certification for high-performance sustainable buildings. LEED awards building projects varying designations of certified, silver, gold or platinum based on the points earned using green strategies and technologies.

Across all versions of LEED, T&S products contribute to initiatives found in the three main LEED rating systems:

  • Building Design + Construction (BD+C)
  • Interior Design + Construction (ID+C)
  • Existing Buildings Operations + Maintenance (O+M)

Specific credit numbers vary based on LEED rating system and associated project type, but in general, T&S products, such as faucets and pre-rinse spray valves, can help contribute to the following categories' prerequisites and credits:

LEED v3

Water Efficiency

WE Prerequisite: Indoor Water Use Reduction (meet or exceed baseline requirements)

WE Credit: Indoor Water Use Reduction (exceed baseline requirements by a designated percentage)

Materials and Resources

Not applicable: Mechanical, Electrical and Plumbing (MEP) products excluded from contributing to points

Innovation in Design

ID Credit: Innovation in Design (multiple options for obtaining points within credit, typically via Path 2 Exemplary Performance.)

Regional Priority

RP Credit: Regional Priority (options for obtaining credit vary by region)

LEED v4

Water Efficiency

WE Prerequisite: Indoor Water Use Reduction (meet or exceed baseline requirements)

WE Credit: Indoor Water Use Reduction (exceed baseline requirements by a designated percentage)

Materials and Resources

Mechanical, Electrical and Plumbing (MEP) products are optional to include in LEED v4. If the project does use this option the following applies:

MR Credit: Building Product Disclosure and Optimization – Sourcing of Raw Materials – Option 2 Leadership Extraction Practices – Recycled Content

Innovation

IN Credit: Innovation (multiple options for obtaining points within credit, typically via Option 3 Additional Strategies/Exemplary Performance.)

Regional Priority

RP Credit: Regional Priority (options for obtaining credit vary by region)

Water Efficiency

Both LEED v3 and LEED v4 continue the required prerequisite of 20% less water than the baseline calculation. Many T&S products meet or exceed these requirements, ensuring certain projects are eligible for contributing toward 1 to 12 LEED points within the Indoor Water Use Reduction credit, depending on the rating system and based on the percentage of water savings for the project. Though other plumbing fixtures like showers and toilets must also pull their weight, T&S products can help earn maximum points in this category.
Current Baseline
Commercial lavatory (restroom) faucets 2.2 gallons per minute (gpm) at 60 pounds per square inch (psi), private applications only (hotel or motel guest rooms, hospital patient rooms) 0.5 (gpm) at 60 (psi) all others except private applications 0.25 gallons per cycle for metering faucets
Commercial pre-rinse spray valves (for foodservice applications) Flow rate ≤ 1.6 GPM (v3)
Flow rate ≤ 1.3 GPM (v4) (no pressure specified; no performance requirement)

Materials and Resources

While plumbing products are excluded from earning points in this category in LEED v3, it is an option in LEED v4 within Building Product Disclosure and Optimization credits: Sourcing of Raw Materials. T&S Brass products do contain 90% post-consumer recycled content material, and we recycle all of our brass chips from machining, buffing and polishing to reduce our demand for virgin mined materials.

Innovation in Design/Innovation

Innovation in Design (v3), or simply Innovation (v4), is a category that encourages creative strategies for conservation. One to five points can be earned through sustainable choices that go beyond the scope of the other point categories. T&S products can contribute in this area, due to significant water conservation features that go “above and beyond” in the Water Efficiency category.

Regional Priority

The environmental needs of Michigan vary significantly from those of Arizona. LEED takes this into account through the Regional Priority category, which is worth from one to four points. Selected by the USGBC’s regional councils, area-specific concerns are identified and plugged into the criteria for the Regional Priority category. Corresponding point values are available for buildings that address particular water zone needs. Water conservation frequently qualifies as a priority, since freshwater has become of great concern in specific locales.
