FREQUENTLY ASKED QUESTIONS

FAQs for Applicability of Plastic Piping Systems to Green Rating Systems

Do your products have to meet LEED requirements, and are they certified to meet LEED requirements?

LEED does not specifically require certification of products. LEED does not rate plumbing products. Therefore, piping and similar products are not eligible to be certified to LEED compliance. If anyone tells you a piping system is “LEED-certified”, the statement is not accurate.

Do USGBC LEED rating systems give credits to buildings for use of certain types of piping material?

No. LEED rating systems do not prefer one piping material over another. LEED NC 2009 contains this language, similar to LEED NC 2.2, in the materials resource (MR) section;

“Mechanical, electrical and plumbing components and specialty items such as elevators and equipment cannot be included in this calculation.”

The calculations in these sections do provide credits for such factors as a product’s recycled content, reused materials, or regional materials.

Since, LEED rating systems exclude piping from the materials credit section which includes Materials Reuse, Recycled Content, and Regional Materials, you should choose the most appropriate piping material for the application.

However, points for your building can be obtained by installing one or more of the sustainable systems listed below that substantially rely on plastic pipe.

How can plastic pipe help achieve credits in LEED or other sustainable building standards or rating systems?

The following sustainable systems provide credits in LEED New Construction (NC) and in LEED for Homes. Most of these systems are empowered by the use of plastic piping;

Gray water reuse and irrigation systems, Water Efficiency 1, 2 (New Construction (NC) / Homes)
Geothermal ground loops for heating and cooling, Energy Efficiency 1 (NC) Energy Efficiency 6 (Homes)
Efficient hot water distribution systems, Energy & Atmosphere 7.1 (Homes)
Rainwater harvesting, Water Efficiency 1, 2 (NC)
Radon venting, Indoor Environmental Quality 9 (Homes)
Central vacuum systems, Indoor Environmental Quality 8.2 (Homes)
Waste water treatment, Water Efficiency 1, 2 (NC)
Efficient irrigation, Water Efficiency 1 (NC)
Foundation drainage, Water Efficiency 1 (NC)
Radiant floor heating, Indoor Environmental Quality 7 (Homes)

Can I use solvent cements in “green” and “sustainable” building rating systems, like LEED?

Yes. LEED V 2.2 and LEED 2009 both require the use of low VOC solvent cements in Environmental Quality credit 4.1 in order to obtain the credit point. Low-VOC solvent cements complying with SCAQMD Rule 1168 are commercially available. Solvent cemented piping systems, like ABS, PVC and CPVC each find uses in sustainable piping systems such as gray water, subsurface irrigation, radon venting, rain water catchment, and higher efficiency hot water distribution.
