LEED ® -NC 2009 Recycled Content Value of Steel Building Products

The following is required by LEED-NC: Credit 4 (1 or 2 points) "Use materials with recycled content such that the sum of postconsumer recycled content plus one-half of the pre-consumer content constitutes at least 10% or 20% (based on cost) of the total value of the materials in the project."

ICF and LEED Certification

Materials & Resources Credit 4 – Recycled Content (2 Points) The polypropylene webs in most ICFs are typically made of 100% post-industrial recycled materials and often make up approximately 60% of the product by weight. In addition, Portland cement used in the form cavity can contain a significant amount of fly ash (recycled).

LEED and Masonry

Concrete masonry that incorporates recycled concrete masonry, glass, slag or other recycled materials as aggregate qualify as post-consumer. (TEK 6-9A) Clay brick often incorporate recycled brick ground and used as grog. If reclaimed from a job site, this material can qualify as post-consumer recycled content.

Concrete Masonry & the LEED® Recycled Content Credit REPORT

“Recycled Content” is one of the key LEED credits for concrete products. The two opportunities for concrete masonry under this credit are the use of recycled materials as aggregate replacements and as cement alternatives.

Concrete Recycled Content

If you only use the cementitious value of the concrete mix, we are using between 20 % and 50% of the cementitious material being fly ash/slag. I understand that LEED wants to encourage the use of fly ash/slag and is allowing the project teams to use this higher value for recycled content. My confusion is whether I use this percentage against the total cost of the concrete mix or if I need to break out the cementitious material cost of the concrete.

Ready-Mix Concrete

The amount of these materials used within a product, such as concrete, contributes to the total recycled materials content of the building and therefore more points may be available. AS&G’s LEED concrete mix designs contain: LEED 1 – LEED 5, 8 and 9 – 20% Recycled Concrete Aggregate (RCA) by weight.

Navigating the Complexities of LEED v4 with Concrete Masonry

May 06, 2016 · The recycled content credit is calculated in the same way as it was in LEED 2009 - that is, the sum of post consumer recycled content. The credit states products meeting the recycled content criteria are valued at 100 percent of their cost in credit calculations.

LEED and Precast (Q&A / Checklist)

7. Do recycled materials in PRECAST concrete (STEEl content, Etc.) contribute to LEED points? Yes, under the recycled content credit MR 4.1 and 4.2. 8. Is the 500-mile-radius requirement for local-material content limited to the finished precast concrete product, or does it also apply to the raw materials?

Asphalt LEED Points - Eco-Agg Concrete Recycling

LEED® Project Certification: Hot Mix Asphalt. Asphalt pavements can help divert waste from landfills, use regionally produced and recycled materials, reduce heat island effect and help manage stormwater. Projects can potentially earn additional credits by using asphalt with high recycled content or warm-mix asphalt.

Leadership in Energy and Environmental Design (LEED®)

Concrete is very durable, lasting much longer than most building materials in similar conditions. Credits for building reuse, recycled content, and regionally available materials are supported by concrete applications. For more in-depth information, see the NRMCA Concrete Use and Sustainability Report, Concrete's Contribution to LEED 2009.

Regional and Recycled Credits in LEED v4

Like with previous versions of LEED, the supplementary cementitious materials used in concrete, such as fly ash, silica fume, and slag cement, are considered post-industrial recycled content. And concrete and its constituents are typically sourced very close to the project site and can add to the material valuation of this credit.
